DESCRIPTION OF EMBODIMENTS

Other features and advantages of the invention will be further understood from the further technological features disclosed by the embodiments of the invention wherein there are shown and described embodiments of this invention, simply by way of illustration of best modes to carry out the invention.

FIG. 1is a schematic view illustrating the solar power system according to one embodiment of the present invention. Referring toFIG. 1, the solar power system1of the present embodiment is suitable for converting sunlight to an electric power. The solar power system includes a heat exchanger10, a heat-focusing device20, a power-generating device30, a power-transforming device40, and a power storage50. The heat exchanger10is set with a first guiding channel C1and a second guiding channel C2mainly. The first guiding channel C1and other channel communicated therewith are capable of flowing for a first heat-exchange fluid F1with higher temperature, for example. The second guiding channel C2and other channel communicated therewith are capable of flowing for a second heat-exchange fluid F2with lower temperature, for example. The first heat-exchange fluid F1is, for example, oil or other appropriate fluids with higher boiling point. The second heat-exchange fluid F2is, for example, water or other appropriate fluids with lower boiling point. The heat-focusing device20is, for example, a heat-focusing mirror. The power-generating device30is, for example, a steam driving device. The power-generating device30and the power-transforming device40constitute a power generation module.

In the present embodiment, heat-focusing device20is suitable for receiving sunlight. Sunlight is focused to the first heat-exchange fluid F1in the first guiding channel C1. Since the first heat-exchange fluid F1is, for example, appropriate fluid with higher boiling point, like oil, the temperature of the first heat-exchange fluid F1rises substantially (approximately 800 degrees Celsius) when the first heat-exchange fluid F1be heated by sunlight. Besides, since the second heat-exchange fluid F2is, for example, appropriate fluid with lower boiling point, like water, the temperature of the second heat-exchange fluid F2in the second guiding channel C2is normal (approximately 20 degrees Celsius). Therefore, the heat exchanger of the invention10has a good heat-exchange efficiency when the first heat-exchange fluid F1and the second heat-exchange fluid F2flows into the heat exchanger10. In other words, the second heat-exchange fluid F2is, for example, liquid. The second heat-exchange fluid F2be heated and vaporized to a steam. The design of the heat exchanger10of the present embodiment will be hereinafter described in detail.

From the above, one end of the power-generating device30is communicated with the outlet O2of the second guiding channel C2(the other end of the power-generating device30is communicated with the inlet I2of the second guiding channel C2). The vaporization of the second heat-exchange fluid F2is suitable for driving the power-generating device30to produces a mechanical energy. The power-transforming device40is connected to the power-generating device30, and transforms the mechanical energy to be an electric power. The power storage50is connected to the power-transforming device40, and used to store the electric power. In addition, in the present embodiment, the other end of the power-generating device30is communicated with the inlet I2of the second guiding channel C2. The vaporization of the second heat-exchange fluid F2will be condensed into liquid again after driving the power-generating device30. The liquid state of the second heat-exchange fluid F2is driven to flow toward the inlet I2of the second guiding channel C2, and performs the heat-exchange process again cyclically.

In addition, the solar power system1of the present embodiment further includes a first heat-exchange fluid tank60, wherein the first heat-exchange fluid tank60has a first heat-exchange fluid tank-inlet62and a first heat-exchange fluid tank-outlet64. The first heat-exchange fluid tank-inlet62is communicated with the outlet O1of the first guiding channel C1. The first heat-exchange fluid tank-outlet64is communicated with the inlet I1of the first guiding channel C1. The first heat-exchange fluid F1completed the heat-exchange process of the heat exchanger10is stored to the first heat-exchange fluid tank60through the first heat-exchange fluid tank-inlet62. The temperature of the first heat-exchange fluid F1completed the heat-exchange process is, for example, about 500 degrees Celsius. The solar power system1further includes a control valve70disposed between the outlet O1of the first guiding channel C1and the first heat-exchange fluid tank60. This provides an appropriate method to control an open state and a close state of the control valve70by the power-generating device30, and further controls the flow of the first heat-exchange fluid F1.

Worth mentioning is that the solar power system1of the present embodiment not only perform the power generation process under sunlight, but also can perform the power generation process without sunlight. In detail, the temperature of the first heat-exchange fluid F1is, for example, about 500 degrees Celsius when the heat-exchange process is completed. The temperature of the first heat-exchange fluid F1still keeps in a high temperature state (higher than 200 degrees Celsius) when the he first heat-exchange fluid F1is stored in the first heat-exchange fluid tank60for sometime. Without sunlight, the present embodiment can apply the first heat-exchange fluid F1to keep in the high temperature state to perform the heat-exchange process. The high temperature state of the first heat-exchange fluid F1makes the second heat-exchange fluid F2steam to produce the above mechanical energy. That is, the solar power system1of the invention can operate in any weather, and has not influence in a cloudy day or at night.

In addition, the solar power system1of the present embodiment also includes a second heat-exchange fluid tank80and a control module90adapted to detect the flow of the second heat-exchange fluid F2. The second heat-exchange fluid tank80is used to store the second heat-exchange fluid F2, and disposed between the power-generating device30and the inlet I2of the second guiding channel C2. Since the second heat-exchange fluid F2is prone to consume in the process of vaporization or in the process of driving the power-generating device30to produce the mechanical energy, the present embodiment applies the control module90to monitor the flow of the second heat-exchange fluid F2and performs a follow-up supplement. In detail, the control module90controls the second heat-exchange fluid tank80to be the open state to process a supplement when the flow of the second heat-exchange fluid F2is lower than a default value. The control module90is constituted of a control unit92and a flow control valve94, for example. The control unit92is used to control the second heat-exchange fluid tank80to be an open state or a close state. In addition, about the flow of the first heat-exchange fluid F1and the second heat-exchange fluid F2, the present embodiment can apply a pump to drive the first heat-exchange fluid F1and the second heat-exchange fluid F2to flow, and make the first heat-exchange fluid F1and the second heat-exchange fluid F2circulate in the solar power system1constantly.

Above description is for the connection between the various components of the solar power system1of the invention. Next, the design of the heat exchanger in the solar power system1of the invention will be illustrated, and the description of how to own a good heat-exchange efficiency to make the solar power system1of the invention has a good photo-electric conversion efficiency is also illustrated.

Referring toFIG. 2AandFIG. 2B, the heat exchanger10inFIG. 2Aincludes a first fin100, a second fin200, a third fin300, a fourth fin400, and a fifth fin500. The first fin100, the second fin200, the third fin300, the fourth fin400, and the fifth fin500are, for example, rectangular sheets, and are contacted along an assembly axis L1. The third fin300and the fourth fin400are, for example, disposed in the two sides of the assembly of the first fin100and the second fin200along the assembly axis L1respectively. Each fifth fin500is, for example, disposed between the first fin100and the second fin200along the assembly axis L1. In the present embodiment, the second fin200is, for example, an inverted state of the first fin100. The inverted state is, for example, the state of the rotating 180 degrees of the first fin100along the assembly axis L1. The second fin200also be other inverted state of the first fin100, including but not limited to this type. In addition, the fourth fin400also is, for example, the inverted state of the third fin300.

The heat exchanger10of the present embodiment is constituted of at least a first fin100and at least a second fin200mainly, and the first fin100and the second fin200will be illustrated in detail as follow. The first fin100has a first body110, a first communicating-groove structure120, a second communicating-groove structure130, and a first connecting-groove structure140. The first communicating-groove structure120, the second communicating-groove structure130, and the first connecting-groove structure140are disposed in first body110, and the first communicating-groove structure120and the second communicating-groove structure130are disposed in the two sides of first body110respectively. The first connecting-groove structure140is disposed in the first body110along a connecting axis L2. The connecting axis L2is, for example, vertical to the assembly axis L1.

In addition, the second fin200has a second body210, a third communicating-groove structure220, a fourth communicating-groove structure230, and a second connecting-groove structure240, and the third communicating-groove structure220, the fourth communicating-groove structure230, and the second connecting-groove structure240are disposed in the second body210. The third communicating-groove structure220and the fourth communicating-groove structure230are disposed in the two sides of the second body210respectively, and the second connecting-groove structure240is disposed in the second body210along the connecting axis L2. The first connecting-groove structure140and the second connecting-groove structure240of the present embodiment are, for example, wavy type structures. The heat-exchange fluid flowed into the heat exchanger1will be collided to have a turbulence constantly by the wavy type structures of the first connecting-groove structure140and the second connecting-groove structure240. This upgrades the heat-exchange efficiency of the fins. The first connecting-groove structure and the second connecting-groove structure in other embodiments are, for example, jagged type structures or appropriate structures capable of increasing the turbulence of the heat-exchange fluid, and the present invention does not have any limitation.

From the above, when the first fin100, the second fin200, the third fin300, the fourth fin400, and the fifth fin500are contacted with each other along the assembly axis L1, the second connecting-groove structure240is communicated with the first communicating-groove structure120and the second communicating-groove structure130, and the first connecting-groove structure140is communicated with the third communicating-groove structure220and the fourth communicating-groove structure230. In detail, in the present embodiment, the projection area of the first communicating-groove structure120and the second communicating-groove structure130of the first fin100in the second body210is overlapped with the second connecting-groove structure240respectively. The projection area of the third communicating-groove structure220and the fourth communicating-groove structure230of the second fin200in the first body110is overlapped with the first connecting-groove structure140respectively. Thus, the first communicating-groove structure120, the second connecting-groove structure240, and the second communicating-groove structure130constitute the first guiding channel C1, and the third communicating-groove structure220, the first connecting-groove structure140, and the fourth communicating-groove structure230constitute the second guiding channel C2.

Further, the projection area of the first communicating-groove structure120and the second communicating-groove structure130of the first fin100in the second body210is overlapped with the two ends of the second connecting-groove structure240respectively. The projection area of the third communicating-groove structure220and the fourth communicating-groove structure230of the second fin200in the first body110is overlapped with the two ends of the first connecting-groove structure140respectively. The projection area of the two ends of the first connecting-groove structure140in the second body210is greater or equal to the area of the third communicating-groove structure220and the fourth communicating-groove structure230respectively. The projection area of the two ends of the second connecting-groove structure240in first body110is greater or equal to the area of the first communicating-groove structure120and the second communicating-groove structure130respectively. Therefore, the second heat-exchange fluid F2can flow to the first connecting-groove structure140from the third communicating-groove structure220smoothly, and then flow to the fourth communicating-groove structure230from the first connecting-groove structure140. The first heat-exchange fluid F1can flow to the second connecting-groove structure240from the first communicating-groove structure120smoothly, and then flow to the second communicating-groove structure130from the second connecting-groove structure240.

In addition, in the present embodiment, the projection area of the first communicating-groove structure120and the second communicating-groove structure130of the first fin100in the second body210is not overlapped with the third communicating-groove structure220and the fourth communicating-groove structure230. The projection area of the first connecting-groove structure140of the first fin100in the second body210is not overlapped with the second connecting-groove structure240. That is, the first guiding channel C1and the second guiding channel C2are not communicated with each other when the first fin100and the second fin200are contacted along the assembly axis L1.

In the present embodiment, the first guiding channel C1is, for example, atype guiding channel. The second guiding channel C2is, for example, atype guiding channel. The across area of the first guiding channel C1is, for example, across the cross-section of the heat exchanger10. Similarly, the across area of the second guiding channel C2also is, for example, across the cross-section of the heat exchanger10. That is, the across area of the first guiding channel C1and the across area of the second guiding channel C2are similar substantially. Therefore, the first heat-exchange fluid F1and the second heat-exchange fluid F2can perform the heat-exchange process effectively by flowing across the heat exchanger10completely. The guiding direction of the fluid in the first guiding channel C1and the guiding direction of the fluid in the second guiding channel C2are, for example, clockwise or counterclockwise simultaneously.

Next, other fins of the present embodiment will be illustrated as follow. The third fin300of the present embodiment has a first inlet structure310and a first outlet structure320, and the fourth fin400has a second inlet structure410and a second the outlet structure420. The third fin300and the fourth fin400are, for example, disposed in the two sides of the assembly of the first fin100and the second fin200along the assembly axis L1respectively. The fifth fin500has a first through hole510, a second through hole520, a third through hole530, and a fourth through hole540. The fifth fin500is, for example, disposed between the first fin100and the second fin200along the assembly axis L1. One side of the first through hole510and one side of the second through hole520are, for example, communicated with the first communicating-groove structure120and the second communicating-groove structure130respectively. Another side of the first through hole510and another side of the second through hole520are, for example, communicated with the two ends of the second connecting-groove structure240respectively. One side of the third through hole530and one side of the fourth through hole540are communicated with the third communicating-groove structure220and the fourth communicating-groove structure230respectively. Another side of the third through hole530and another side of the fourth through hole540are, for example, of communicated with the two ends of the first connecting-groove structure140respectively.

From the above, the first inlet structure310and the first outlet structure320of the third fin300are, for example, connected to the two ends of the first guiding channel C1. The second inlet structure410and the second the outlet structure420of the fourth fin400are, for example, connected to the two ends of the second guiding channel C2. The first inlet structure310of the third fin300is communicated with the first communicating-groove structure120of the first fin100. The first outlet structure320of the third fin300is communicated with the second communicating-groove structure130of the first fin100. The second inlet structure410of the fourth fin400is communicated with the third communicating-groove structure220of the second fin200. The second the outlet structure420of the fourth fin400is communicated with the fourth communicating-groove structure230of the second fin200. Since the first guiding channel C1and the second guiding channel C2are not communicated with each other, the projection area of the first inlet structure310and the first outlet structure320of the third fin300in the fourth fin400is not overlapped with the second inlet structure410and the second the outlet structure420.

Besides, the first through hole510and the second through hole520of the fifth fin500are communicated with the first guiding channel C1, and the third through hole530and the fourth through hole540of the fifth fin500are communicated with the second guiding channel C2. The fifth fin500disposed between the first fin100and the second fin200is provided for the first heat-exchange fluid F1with higher temperature and the second heat-exchange fluid F2with lower temperature to flow simultaneously, and increases the heat-exchange process between the first heat-exchange fluid F1and the second heat-exchange fluid F2.

In addition to the capability of providing the first heat-exchange fluid F1with higher temperature and the second heat-exchange fluid F2with lower temperature to flow in the fifth fin500simultaneously, since the first guiding channel C1for the first heat-exchange fluid F1with higher temperature includes the first communicating-groove structure120of the first fin100, the second communicating-groove structure130of the first fin100, and the second connecting-groove structure240of the second fin200, and the second guiding channel C2for the second heat-exchange fluid F2with lower temperature includes the first connecting-groove structure140of the first fin100, the third communicating-groove structure220of the second fin200, and the fourth communicating-groove structure230of the second fin200, the first fin100and the second fin200are also capable of flowing of the first heat-exchange fluid F1with higher temperature and the second heat-exchange fluid F2with lower temperature. Therefore, the design of the first fin100and the second fin200can increases the heat-exchange process between the first heat-exchange fluid F1and the second heat-exchange fluid F2. The first connecting-groove structure140like the wavy type structure in the first fin100and the second connecting-groove structure240like the wavy type structure in the second fin200like the wavy type structure further have the capability of making a constant turbulence of the first heat-exchange fluid F1and the second heat-exchange fluid F2to upgrade the heat-exchange efficiency. Thus, the heat exchanger10of the present embodiment has better heat-exchange performance.

FIG. 3Ais a schematic view illustrating the heat exchanger according to another embodiment of the present invention.FIG. 3Bis an exploded view illustrating the heat exchanger depicted inFIG. 3A.FIG. 3Cis an enlarged schematic view illustrating a region of R depicted inFIG. 3B.FIG. 3Dis a plane schematic view illustrating the heat exchanger depicted inFIG. 3B.FIG. 3Eis an enlarged schematic view illustrating the first fin depicted inFIG. 3D.FIG. 3Fis an enlarged schematic view illustrating the second fin depicted inFIG. 3D. Referring toFIG. 3A,FIG. 3B,FIG. 3C,FIG. 3D,FIG. 3E, andFIG. 3F, the heat exchanger10′ of the present embodiment includes a first fin100′, a second fin200′, a third fin300′, a fourth fin400′, a fifth fin500′, and a sixth fin600′. The first fin100′, the second fin200′, the third fin300′, the fourth fin400′, the fifth fin500′, and sixth fin600′ are, for example, rectangular sheets, and are contacted along an assembly axis L1.

The third fin300′ and the fourth fin400′ are disposed in the two sides of the assembly of the first fin100′ and the second fin200′ along the assembly axis L1respectively. The fifth fin500′ and sixth fin600′ are disposed in the two sides of the assembly of the first fin100′, the second fin200′, the third fin300′, and the fourth fin400′ along the assembly axis L1respectively. In the present embodiment, the second fin200′ is, for example, an inverted state of the first fin100′. The inverted state is, for example, the state of the rotating 180 degrees of the first fin100′ along the assembly axis L1. The second fin200′ also be other inverted states of the first fin100′, including but not limited to this type. In addition, the fourth fin400′ is, for example, an inverted state of the third fin300′, and the sixth fin600′ is, for example, an inverted state of the fifth fin500′.

The heat exchanger10′ of the present embodiment is constituted of at least a first fin100′ and at least a second fin200′ mainly, and the first fin100′ and the second fin200′ will be illustrated in detail as follow. The first fin100′ has a first body110′, a first communicating-groove structure120′, a second communicating-groove structure130′, and a first connecting-groove structure140′, wherein the first communicating-groove structure120′, the second communicating-groove structure130′, and the first connecting-groove structure140′ are disposed in first body110′. In addition, the second fin200′ has a second body210′, a third communicating-groove structure220′, a fourth communicating-groove structure230′, and a second connecting-groove structure240′, wherein the third communicating-groove structure220′, the fourth communicating-groove structure230′, and the second connecting-groove structure240′ are disposed in the second body210′.

When the first fin100′, the second fin200′, the third fin300′, the fourth fin400′, the fifth fin500′, and sixth fin600′ are contacted along the assembly axis L1, the second connecting-groove structure240′ is communicated with the first communicating-groove structure120′ and the second communicating-groove structure130′. The first connecting-groove structure140′ is communicated with the third communicating-groove structure220′ and the fourth communicating-groove structure230′. In detail, the first connecting-groove structure140′ is constituted of multiple first connecting-groove assemblies142′ arranged in the first body110′ along a disposing axis L3in the present embodiment. The second connecting-groove structure240′ is constituted of multiple second connecting-groove assemblies242′ arranged in the second body210′ along the disposing axis L3. The disposing axis L3is, for example, vertical to the assembly axis L1. One end of each second connecting-groove assembly242′ of the second fin200′ is overlapped with the first communicating-groove structure120′ of the adjacent first fin100′ along a connecting axis L2. The other end of the second connecting-groove assembly242′ is overlapped with the second communicating-groove structure130′ of the first fin100′. One end of each first connecting-groove assembly142′ of the first fin100′ is overlapped with the third communicating-groove structure220′ of the adjacent second fin200′ along the connecting axis L2. The other end of the first connecting-groove assembly142′ is overlapped with the fourth communicating-groove structure230′ of the second fin200′. Therefore, the first communicating-groove structure120′, the second connecting-groove structure240′, and the second communicating-groove structure130′ constitute the first guiding channel C1′, and the third communicating-groove structure220′, the first connecting-groove structure140′, and the fourth communicating-groove structure230′ constitute the second guiding channel C2′. The assembly axis L1, the disposing axis L3, and the connecting axis L2are, for example, vertical to each other.

Further, in the present embodiment, the projection area of the first communicating-groove structure120′ and the second communicating-groove structure130′ of the first fin100′ in the second body210′ is not overlapped with the third communicating-groove structure220′ and the fourth communicating-groove structure230′. The projection area of the first connecting-groove structure140′ of the first fin100′ in the second body210′ is not overlapped with the second connecting-groove structure240′. That is, when the first fin100′ and the second fin200′ are contacted along the assembly axis L1, the first guiding channel C1′ and the second guiding channel C2′ are not communicated with each other. Therefore, the second heat-exchange fluid F2can flow to the first connecting-groove structure140′ from the third communicating-groove structure220′ smoothly, and flow to the fourth communicating-groove structure230′ from the first connecting-groove structure140′ smoothly. The first heat-exchange fluid F1can flow to the second connecting-groove structure240′ from the first communicating-groove structure120′ smoothly, and flow to the second communicating-groove structure130′ from the second connecting-groove structure240′ smoothly.

Worth mentioning is that, the first connecting-groove structure140′ and the second connecting-groove structure240′ are constituted of multiple first connecting-groove assemblies142′ and multiple second connecting-groove assemblies242′ respectively, the first heat-exchange fluid F1flowed into the first guiding channel C1′ and the second heat-exchange fluid F2flow into the second guiding channel C2′ can be separated by the first connecting-groove assemblies142′ and the second connecting-groove assembly242′ respectively. Therefore, the heat-exchange efficiency between the heat-exchange fluid and fins is upgraded by the separations of the first heat-exchange fluid F1flowed into the first guiding channel C1′ and the second heat-exchange fluid F2flowed into the second guiding channel C2′. The above separation further makes a heat-exchange efficiency between the first heat-exchange fluid F1in the first guiding channel C1′ and the second heat-exchange fluid F2in the second guiding channel C2′.

In the present embodiment, the first guiding channel C1′ is, for example, capable of flowing for the first heat-exchange fluid F1with higher temperature, and the second guiding channel C2′ is, for example, capable of flowing for the second heat-exchange fluid F2with lower temperature. The first guiding channel C1′ is, for example, atype guiding channel. The second guiding channel C2′ is, for example, atype guiding channel. The across area of the first guiding channel C1′ is, for example, across the cross-section of the heat exchanger10′. Similarly, the across area of the second guiding channel C2′ also is, for example, across the cross-section of the heat exchanger10′. That is, the across area of the first guiding channel C1′ and the across area of the second guiding channel C2′ are similar substantially. Therefore, the first heat-exchange fluid F1and the second heat-exchange fluid F2can perform the heat-exchange process effectively by flowing across the heat exchanger10′ completely. The guiding direction of the fluid in the first guiding channel C1′ and the guiding direction of the fluid in the second guiding channel C2′ are, for example, clockwise or counterclockwise simultaneously.

From the above, in order to have a better heat-exchange efficiency by frequent separations, the first communicating-groove structure120′ is also constituted of multiple first communicating-groove assemblies122′ arranged in the first body110′ along the disposing axis L3, and the third communicating-groove structure220′ is constituted of multiple third communicating-groove assemblies222′ arranged in the second body210′ along the disposing axis L3in the present embodiment. One end of each second connecting-groove assembly242′ of the second fin200′ is overlapped with the first communicating-groove assembly122′ of the adjacent first fin100′ along the connecting axis L2, and the other end of the second connecting-groove assembly242′ is overlapped with the second communicating-groove structure130′ in the connecting axis L2when the first fin100′ and the second fin200′ are contacted. Similarly, one end of each first connecting-groove assembly142′ of the first fin100′ is overlapped with the third communicating-groove assembly222′ of the adjacent second fin200′ along the connecting axis L2, and the other end of the first connecting-groove assembly142′ is overlapped with the fourth communicating-groove structure230′ along the connecting axis L2.

Especially, in order to increase the heat-exchange area between the heat-exchange fluid and the fin, each first communicating-groove assembly122′ of the present embodiment has at least a first communicating-groove unit122a′ arranged in the first body110′ along the connecting axis L2, each first connecting-groove assembly142′ has at least a first connecting-groove unit142a′ arranged in the first body110′ along the connecting axis L2, each third communicating-groove assembly222′ has at least a third communicating-groove unit222a′ arranged in the second body210′ along the connecting axis L2, and each second connecting-groove assembly242′ has at least a second connecting-groove unit242a′ arranged in the second body210′ along the connecting axis L2. The connecting-groove unit or the communicating-groove unit is, for example, a strip type structure or other appropriate structure.

One end of the second connecting-groove unit242a′ of the second fin200′ is overlapped with one end of the first communicating-groove unit122a′ of the adjacent first fin100′, and the other end of the second connecting-groove unit242a′ is overlapped with one end of another first communicating-groove unit122a′ of the first fin100′ or the second communicating-groove structure130′ of the first fin100′. One end of the first connecting-groove unit142a′ of the first fin100′ is overlapped with one end of the third communicating-groove unit222a′ of the adjacent e second fin200′, and the other end of the first connecting-groove unit142a′ is overlapped with one end of another third communicating-groove unit222a′ of the second fin200′ or the fourth communicating-groove structure230′ of the second fin200′. The two first communicating-groove units122a′ overlapped with the second connecting-groove unit242a′ are arranged in the first body110′ along the connecting axis L2adjacently, and the two third communicating-groove units222a′ overlapped with the first connecting-groove unit142a′ are arranged in the second body210′ along the connecting axis L2adjacently. It increases the heat-exchange area between the heat-exchange fluid and the fin substantially by the design of each groove assembly having at least a groove unit, and further upgrades the heat-exchange efficiency of the heat exchanger10′. In the present embodiment, the first communicating-groove assembly122′ is, for example, constituted of two first communicating-groove units122a′. The first connecting-groove assembly142′ is, for example, constituted of two first connecting-groove units142a′. The third communicating-groove assembly222′ is, for example, constituted of two third communicating-groove units222a′. The second connecting-groove assembly242′ is, for example, constituted of two second connecting-groove units242a′. About the groove assembly is, for example, constituted of two groove units, the present invention does not have any limitation.

On the other hand, because of partial overlap between the end of the second connecting-groove unit242a′ and the end of the first communicating-groove unit122a′, partial overlap between the end of second connecting-groove unit242a′ and the end of the second communicating-groove structure130′, partial overlap between the end of the first connecting-groove unit142a′ and the end of the third communicating-groove unit222a′, and partial overlap between the end of the first connecting-groove unit142a′ and the end of the fourth communicating-groove structure230′, the heat-exchange fluid flowed to any connecting-groove unit or any communicating-groove unit be separated into two communicating-groove units with partial overlap or two connecting-groove units with partial overlap. The above heat-exchange fluid separated into two communicating-groove units or two connecting-groove units will be confluent to the connecting-groove unit overlapped with the two communicating-groove units simultaneously or the communicating-groove unit overlapped with the two communicating-groove units simultaneously. That is, the heat-exchange fluid will be separated and confluent in the process of flowing through each groove unit constantly. Therefore, there being have a maximum contact area between each fin and the heat-exchange fluid in the process of the heat-exchange fluid flowing through the heat exchanger10′. The heat-exchange process will be performed between the heat-exchange fluids flowing through each connecting-groove unit or communicating-groove unit and the heat exchanger10′, further make the heat exchanger10′ have a good heat-exchange efficiency.

Furthermore, in order to have a shorter and direct heat-exchange path between the first heat-exchange fluid F1with higher temperature in the first guiding channel C1′ and the second heat-exchange fluid F2with lower temperature in the second guiding channel C2′ in the present embodiment, the first communicating-groove assemblies122′ and the first connecting-groove assemblies142′ arranged in the first body110′ are staggered along the disposing axis L3, and the third communicating-groove assemblies222′ and the second connecting-groove assemblies242′ arranged in the second body210′ are staggered along the disposing axis L3similarly.

Therefore, there will be a shorter and direct heat-exchange path between the first heat-exchange fluid F1with higher temperature in the first guiding channel C1′ and the second heat-exchange fluid F2with lower temperature in the second guiding channel C2′, thereby allowing the heat-exchange process of the heat exchanger10′ efficiently.

When the first fin100″, the second fin200″, the third fin300″, the fourth fin400″, the fifth fin500″, and the sixth fin600″ are contacted along the assembly axis L1, the projection area of the second connecting-groove structure240″ in first body110″ is overlapped with the first communicating-groove structure120″ and the second communicating-groove structure130″, and the projection area of the first connecting-groove structure140″ in the second body210″ is overlapped with the third communicating-groove structure220″ and the fourth communicating-groove structure230″.

The other end of the second connecting-groove unit242a″ is overlapped with one end of another first communicating-groove unit122a″ of the first fin100″ or the second communicating-groove structure130″ of the first fin100″.

Similarly, because of the third communicating-groove structure220″ having multiple third communicating-groove assemblies222″ arranged in the second body210″ along the disposing axis L3and each third communicating-groove assembly222″ having multiple third communicating-groove units222a″ arranged in the second body210″ along the connecting axis L2, one end of the first connecting-groove unit142a″ of the first fin100″ is overlapped with one end of the third communicating-groove unit222a″ of the adjacent second fin200″. The other end of the first connecting-groove unit142a″ is overlapped with one end of another third communicating-groove unit222a″ of the second fin200″ or the fourth communicating-groove structure230″ of the second fin200″.

The two third communicating-groove units222a″ overlapped with the first connecting-groove unit142a″ are arranged in the second body210″ along the connecting axis L2adjacently.

As a result, the first guiding channel C1″ is constituted of the first communicating-groove structure120″, the second connecting-groove structure240″, and the second communicating-groove structure130″, and the second guiding channel C2″ is constituted of the third communicating-groove structure220″, the first connecting-groove structure140″, and the fourth communicating-groove structure230″. The assembly axis L1, the disposing axis L3, and the connecting axis L2are, for example, vertical to each other.

In addition, in the present embodiment, the first guiding channel C1″ is, for example, capable of flowing for the first heat-exchange fluid F1with higher temperature, and the second guiding channel C2″ is, for example, capable of flowing for the second heat-exchange fluid F2with lower temperature. The first guiding channel C1″ is, for example, atype guiding channel. The second guiding channel C2″ is, for example, atype guiding channel. The across area of the first guiding channel C1″ is, for example, across the cross-section of the heat exchanger10″. Similarly, the across area of the second guiding channel C2″ also is, for example, across the cross-section of the heat exchanger10″. That is, the across area of the first guiding channel C1″ and the across area of the second guiding channel C2″ are similar substantially. Therefore, the first heat-exchange fluid F1and the second heat-exchange fluid F2can perform the heat-exchange process effectively by flowing across the heat exchanger10″ completely.

Different from the heat exchanger10′ of the above embodiment, in the present embodiment, multiple groove units arranged along the connecting axis L2can be defined to a groove unit arrangement, and each groove assembly is constituted of multiple groove unit arrangements A. One groove assembly is constituted of the adjacent groove unit arrangements A staggered with each other. That is, the first communicating-groove unit122a″ of each first communicating-groove assembly122″ is staggered with the adjacent first communicating-groove unit122a″, the first connecting-groove unit142a″ of each first connecting-groove assembly142″ is staggered with the adjacent first connecting-groove unit142a″, the third communicating-groove unit222a″ of each third communicating-groove assembly222″ is staggered with the adjacent third communicating-groove unit222a″, and the second connecting-groove unit242a″ of each second connecting-groove assembly242″ is staggered with the adjacent second connecting-groove unit242a″.

Therefore, when the first fin100″ and the second fin200″ are contacted along the assembly axis L1, the second connecting-groove unit242a″ of the second fin200″ is communicated with the two adjacent first communicating-groove units122a″ arranged along the disposing axis L3and the two adjacent first communicating-groove units122a″ arranged along the connecting axis L2in the first fin100″, the first connecting-groove unit142a″ of the first fin100″ is communicated with the two adjacent third communicating-groove units222a″ arranged along the disposing axis L3and the two adjacent third communicating-groove units222a″ arranged along the connecting axis L2in the second fin200″. That is, one second connecting-groove unit242a″ is communicated with four adjacent first communicating-groove units122a″ of the first fin100″, and one first connecting-groove unit142a″ is communicated with four adjacent third communicating-groove units222a″ of the second fin200″. Although the above illustration take one connecting-groove unit communicated with adjacent four communicating-groove units for example, but the design of one connecting-groove unit communicated with adjacent four communicating-groove units are all within the spirit and scope of this invention, including but not limited to this type.

From the above, the present embodiment also has better heat-exchange efficiency by the design of one connecting-groove unit communicated with multiple adjacent communicating-groove units and frequent flow separation. The design of each groove assembly constituted of multiple groove units further increases the heat-exchange area between the heat-exchange fluid and the fin substantially, and upgrades the heat-exchange efficiency of the heat exchanger10″. In addition, because of one end of the two connected groove units overlapped with each other partially in the present embodiment, the heat-exchange fluid flowed to the connecting-groove unit or the communicating-groove unit will be separated or confluent continuously by the groove wall as described in above embodiment. Therefore, in the process of the heat-exchange fluid flowing through the heat exchanger10″, there will be a largest contact area between each fin and the heat-exchange fluid, and the heat exchanger10″ can perform the heat-exchange process in each connecting-groove unit or communicating-groove unit with the heat-exchange fluid, and make the heat exchanger10″ have a good heat-exchange efficiency.

Worth mentioning is that the groove units of the present embodiment are, for example, a diamond type structure. The inner wall of the groove unit has at least a slope structure, so that the heat-exchange fluid will separated toward multiple directions after the heat-exchange fluid colliding with the end of the groove unit. There will be produced a serious turbulence to make the heat-exchange fluid in one section perform the heat-exchange stably.

Afterwards, other fins of the present embodiment will be illustrated as follow. The third fin300″ of the present embodiment has a first inlet structure310″ and a first outlet structure320″, and the fourth fin400″ has a second inlet structure410″ and a second the outlet structure420″. The first inlet structure310″ and the first outlet structure320″ are connected to the two ends of the first guiding channel C1″, and the second inlet structure410″ and the second the outlet structure420″ are connected to the two ends of the second guiding channel C2″. The first outlet structure320″ of the third fin300″ is, for example, constituted of multiple first the outlet units322″ arranged along the disposing axis L3. The second the outlet structure420″ is, for example, constituted of multiple second the outlet unit422″ arranged along the disposing axis L3.

Therefore, when the third fin300″ and the fourth fin400″ are disposed in the two sides of the assembly of the first fin100″ and the second fin200″ along the assembly axis L1respectively, the first the outlet units322″ and the second communicating-groove structure130″ are communicated with each other, and the second the outlet units422″ and the fourth communicating-groove structure220″ are communicated with each other. That is, the first outlet structure320″ is communicated with the second communicating-groove structure130″, and the second the outlet structure420″ is communicated with the fourth communicating-groove structure230″. In addition, in the present embodiment, the first inlet structure310″ is communicated with the first communicating-groove structure120″, and the second inlet structure410″ is communicated with the third communicating-groove structure220″. The first outlet structure320″ of the third fin300″ is, for example, constituted of multiple first the outlet units322″ arranged along the disposing axis L3. The second outlet structure410″ is, for example, constituted of multiple second outlet units422″ arranged along the disposing axis L3. The design can increase the heat-exchange area between the heat-exchange fluid and the fin.

In addition, the fifth fin500″ has a first through hole510″ and a second through hole520″, the sixth fin600″ has a third through hole610″ and a fourth through hole620″, one side of the first inlet structure310″ is communicated with the first communicating-groove structure120″, another side of the first inlet structure310″ is communicated with the first through hole510″, one side of the first outlet structure320″ is communicated with the second communicating-groove structure130″, another side of the first outlet structure320″ is communicated with the second through hole520″, one side of the second inlet structure410″ is communicated with the third communicating-groove structure220″, another side of the second inlet structure410″ is communicated with the third through hole610″, one side of the second the outlet structure420″ is communicated with the fourth communicating-groove structure230″, another side of the second the outlet structure420″ is communicated with the fourth through hole620″.

As a result, the first heat-exchange fluid F1with higher temperature can flow into the first guiding channel C1′ through the first through hole510″ and the first inlet structure310″, and flow out of the heat exchanger10″ through the first outlet structure320″ and the second through hole520″ after flowing out of the first guiding channel C1″. On the other hand, the second heat-exchange fluid F2with lower temperature can flow into the second guiding channel C2″ through the third through hole610″ and the second inlet structure410″, and flow out of the heat exchanger10″ through the second the outlet structure420″ and fourth through hole620″ after flowing out of the second guiding channel C2″. By the above connection, the heat-exchange process can be performed between the first heat-exchange fluid F1with higher temperature and the second heat-exchange fluid F2with lower temperature of the heat exchanger10′. Similar to the heat exchanger10′ of the above embodiment, the heat exchanger10″ of the present embodiment further includes a seventh fin700″ and a eighth fin800″. The seventh fin700″ and the eighth fin800″ are disposed in the two sides of the assembly of the first fin100″, the second fin200″, the third fin300″, the fourth fin400″, the fifth fin500″, and sixth fin600″ along the assembly axis L1, and the heat-exchange fluids can flow into or out of the heat exchanger10″ through a opening disposed in the seventh fin700″ or the eighth fin800″.

The present embodiment takes the stagger of a first fin100″ and a second fin200″ along the assembly axis L1mainly. In other embodiments, multiple first fins100″ can be assembled in advance, and multiple second fins200″ can be assembled in advance. And then, the assembly of the first fins100″ and the assembly of the second fins200″ can be staggered to constitute another heat exchanger. About the staggered method of the assembly of the first fins100″ and the second fins200″, the present invention does not have any limitation. In addition, the present embodiment is constituted of at least a first fin100″ and at least a second fin200″ mainly, the assembled type of the third fin300″, the fourth fin400″, the fifth fin500″, the sixth fin600″, the seventh fin700″, and the eighth fin800″ opposite to the location of the first fin100″ and the second fin200″ as described in above is one of various embodiments. It is within the scope and spirit of the present invention as long as the appropriate disposing type for the first guiding channel C1″ and the second guiding channel C2″ flowing smoothly, and the present invention does not have any limitation.

Whether the heat exchanger10, the heat exchanger10′, or the heat exchanger10″ also has a good heat-exchange efficiency, and make the solar power system1of the invention upgrade the photo-electric conversion efficiency of the solar power system1efficiently and substantially.

To sum up, in the solar power system of the invention, at least two fins are set with multiple communicating-groove structures and connecting-groove structure in the heat exchanger respectively. In each fin, a communicating-groove structure is not communicated with a connecting-groove structure, and one communicating-groove structure is not communicated with another communicating-groove structure. When the fins are assembled, a communicating-groove structure of one fin is communicated with the adjacent communicating-groove structure through a connecting-groove structure of another fin. The communicating-groove structures are disposed in heat exchanger densely by various arrangements, further have a guiding channel with a good heat-exchange efficiency. Thus, the heat exchanger of the invention has two guiding channels to perform the heat-exchange process for the fluids with different temperatures.

In addition, since the heat exchanger of the invention is assembled by at least two types of fins staggered with each other and each fin has multiple communicating-groove structures and a connecting-groove structure, the heat-exchange fluid is forced to be confluent or separated constantly when The heat-exchange fluid flows into the heat exchanger. This increases the contact area between the heat-exchange fluid and heat exchanger substantially, and increases the rate of the heat-exchange process of heat-exchange fluids to achieve good heat-exchange performance. Therefore, the second heat-exchange fluid is, for example, water. The first heat-exchange fluid is, for example, oil. The second heat-exchange fluid can be vaporized into steam rapidly and efficiently when the first heat-exchange fluid is heated via sunlight by the heat exchanger of the invention. The steam is applied to drive the power-generating device to produce a mechanical energy. The mechanical energy is transformed to an electric power, and the photo-electric conversion efficiency of the solar power system is upgraded substantially.

Furthermore, the solar power system of the invention not only performs the power generation process under sunlight, but also can perform the power generation process without sunlight. Without sunlight, the invention can apply the first heat-exchange fluid to keep in the high temperature state to perform the heat-exchange process. The high temperature state of the first heat-exchange fluid makes the second heat-exchange fluid steam to produce the above mechanical energy.

Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiments may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims rather than by the above detailed descriptions.
