BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a current stabilization and pressure boosting device for evaporator; in particular, it relates to a heat-sinking structure which is capable of internally performing liquid-to-gas conversions on liquid water in order to achieve the heat dissipation function and is suitable for various electronic components with respect to heat dissipation purpose.

2. Description of Related Art

In recent years, the heat generation of electronic components has been increasing rapidly with the precision improvements of semiconductor processes. Therefore, how to enhance the heat-sinking capability of electronic components in order to maintain the normal operations of components has become a very important engineering issue. Direct air cooling technology, which has been comprehensively utilized in various fields at present, is no longer appropriate for fulfilling heat dissipation requirements of many electronic components featuring high heat flux, indicating that other solutions need to be sought.

Among the existing technologies, in addition to the aforementioned air-cooling technology, there is also another type of technology which applies liquid-to-gas conversion of water to achieve the heat dissipation effect. This technology provides two sets of heat spreaders and two sets of connected pipes, in which one set of heat spreaders is used to evaporate in order to remove the heat absorbed by water, while the other set of heat spreaders used to condense so as to cool down to bring back the outputted water for subsequent cooling processes to achieve the heat dissipation effect. It can be seen that the pressures in such two sets of heat spreaders are different, so the water can be automatically transported back and forth during operations thus forming a cycling loop. However, since there will be a large amount of water circulating inside the heat spreaders, in case the water circulation path is not restricted, the internal water is prone to leakage problems, and the pressure cannot be properly maintained therein, thus probably disturbing the internal water circulation condition and adversely affecting the usage efficiency thereof.

Therefore, to address the above-said issues, a heat-sinking module has been designed which can block the water inside the heat-sinking module from directly contacting the outer case in order to eliminate leakage problems, and also restrict the water flow direction so as to effectively retain the water heated and evaporated within the heat-sinking module thereby quickly raising the internal pressure such that water can be stably and quickly discharged in order to improve the stability of the water flow; accordingly, the present invention provides a current stabilization and pressure boosting device for evaporator as the optimal solution.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Other technical contents, aspects and effects in relation to the present invention can be clearly appreciated through the detailed descriptions concerning the preferred embodiments of the present invention in conjunction with the appended drawings.

Refer first toFIGS. 1˜2, wherein a stereo view and an internally structural cross-sectioned view of a current stabilization and pressure boosting device for evaporator according to the present invention are respectively shown. As shown in these Figures, the first embodiment of the current stabilization and pressure boosting device for evaporator according to the present invention comprises a heat-sinking module1and an outer case2.

Herein heat-sinking module1is assembled by successively stacking a large number of heat-sinking components11, with each of the heat-sinking components11having a first board surface111, a second board surface112and a third board surface113, in which the first board surface111, second board surface112and third board surface113are integrally formed or fixedly attached with each other, such that the insides of such heat-sinking components11form a semi-open inner flow channel114; besides, a fourth board surface115is further respectively provided at the two ends of the heat-sinking components11opposite to the inner flow channel114, and the heat-sinking module1is respectively configured with a water injection channel12and an air exhausting channel13(i.e., part of the heat-sinking components11are provided with the water injection channel12, and part of the heat-sinking components11are provided with the air exhausting channel13), and the heat-sinking module1can be openly configured with at least one channel14penetrating through each of the heat-sinking components11.

Meanwhile, the outer case2is internally configured with a chamber21for placing the heat-sinking module1, with the two sides of the heat-sinking components11being closely attached to the inside of the chamber21, and the outer case2also includes an outer lid11for covering in fit the chamber21; in addition, and the outer case2is further respectively configured with a water inlet23and an air outlet24, in which the water inlet23corresponds to the position of the water injection channel12, and the air outlet24corresponds to the position of the air exhausting channel13.

Refer next toFIGS. 3˜6, and it can be seen that an electronic component4can be locked onto the bottom surface of the outer case2; also, heat-sinking fins5and a connection tube6can be conjunctively installed on the outer lid22, and the connection tube6is connected to a condenser7.

When the electronic component4generates heat, the thermal energy generated by the electronic component4can be introduced into the interior of the outer case2and conducted to the heat-sinking module1, so the heat dissipated by the heat-sinking module1causes the internal liquid water to evaporate into gaseous water which then passes upward through the air exhausting channel13and the air outlet24and sequentially enters the connection tube6to the condenser7; herein the gaseous water entering the condenser7will become liquid water after cooling, thus passing through the connection tube6and returning back into the heat-sinking module1.

The backflow of liquid water will sequentially pass through the water inlet23and the water injection channel12into each of the inner flow channels114, and then circulate through each of the channels14to all parts of each of the heat-sinking module1; therefore, repeatedly, it evaporates into gaseous water and can be continuously circulated to achieve the purpose of circulating heat dissipation.

Next, refer toFIGS. 5 and 7, wherein the fourth board surface115is installed at the two ends of each of the inner flow channels114so that liquid water or gaseous water in each of the inner flow channels114will not be able to directly contact the chamber21and the outer lid22from the two ends of the inner flow channel114, thereby preventing the overflow or leakage issues at the joints; at the same time, a large amount of liquid water or gaseous water is retained in each of the inner flow channels114, and the liquid water is stably heated and evaporated to allow gaseous water, especially the gaseous water blocked at both ends of each of the inner flow channels114, to rapidly increase the internal pressure in order to create a high pressure therein which then quickly forces the gaseous water to be discharged from the air exhausting channel13such that the internal water flow can be stabilized.

Subsequently,FIG. 2shows a first embodiment for the heat-sinking component11of the current stabilization and pressure boosting device for evaporator according to the present invention. It can be seen that the fourth board surface115of the heat-sinking component11is formed by the two ends of the first board surface111extending in the direction of the inner flow channel114, and the extension length of the fourth board surface115is the same as that of the second board surface112and the third board surface113, and the fourth board surface115is completely blocked at the two ends of each of the inner flow channels114. Besides, refer toFIG. 8A, which illustrates a second embodiment of the heat-sinking component11, wherein this fourth board surface115is formed by the two ends of the first board surface111extending towards the upside in the direction of the inner flow channel114, and the extension length of the fourth board surface115is the same as that of the second board surface112and the third board surface113, and the fourth board surface115is blocked only at the upside on the two ends of each of the inner flow channels114.

Also, refer toFIG. 8C, which illustrates a fourth embodiment of the heat-sinking component11, wherein the fourth board surface115is formed by the two ends of the first board surface111extending towards the direction of the inner flow channel114, and the extension length of the fourth board surface115is shorter than that of the second board surface112and the third board surface113, and the fourth board surface115is incompletely blocked on the two ends of each of the inner flow channels114. Moreover, refer toFIG. 8D, which illustrates a fifth embodiment of the heat-sinking component11, wherein the fourth board surface115is formed by the two ends of the first board surface111extending towards the upside in the direction of the inner flow channel114, while the downside of the two ends of the first board surface111extends towards outside to form a protrusion section116, and the extension length of the fourth board surface115is the same as that of the second board surface112and the third board surface113, and the fourth board surface115is blocked only at the upside on the two ends of each of the inner flow channels114.

It should be understood that the first embodiment is in the form of full blocking, while the second to sixth embodiments are in the form of half blocking, so that the user may select one type of the above-mentioned heat-sinking components11in the intended configuration. That is, If the heat-sinking component11in the full-blocking type is used, then the heat-sinking module1must be configured with at least one channel14penetrating each of the heat-sinking components11; in contrast, if the heat-sinking component11in the half-blocking type is used, then the heat-sinking module1can be selectively configured with or without the channel14.

Meanwhile, a large amount of liquid water or gaseous water is retained in each of the inner flow channels114, and the liquid water is stably heated and evaporated to allow gaseous water, especially the gaseous water blocked at both ends of each of the inner flow channels114, to rapidly increase the internal pressure in order to create a high pressure therein which then quickly forces the gaseous water to be discharged from the air exhausting channel13such that the internal water flow can be stabilized. In addition, each of the heat-sinking components11applies the half-blocking configuration as illustrated in the above-said second to sixth embodiments (corresponding toFIGS. 8A, 8B, 8C, 8D and 8E, and herein the second embodiment is used in the Figure), and a notch31is openly provided on the impedance block3with respect to the two ends of each of the inner flow channels114in order to maintain a space for liquid water or gaseous water to flow through.

Refer next toFIG. 11, in which a third embodiment for the integral structure configuration of the current stabilization and pressure boosting device for evaporator according to the present invention is shown, which exhibits an extension of the second embodiment. In the present embodiment, a predetermined space is configured between the two ends of each of the heat-sinking components11and the inner lateral surface of the chamber21, and each of the impedance blocks3is disposed on a side of the outer cover22opposite to the chamber21, so that, when the outer lid22covers in fit the chamber21, each of the impedance blocks3can be inserted between the two ends of the heat-sinking components11and the inner surface of the chamber21; moreover, each of the heat-sinking components11uses a half-blocking configuration illustrated in the second to sixth embodiments (equivalent toFIGS. 8A, 8B, 8C, 8D and 8E, and the Figure uses the second embodiment), and a notch31is openly provided on the impedance block3with respect to the two ends of each of the inner flow channels114in order to maintain a space for liquid water or gaseous water to flow through.

In the present embodiment, a predetermined space is configured between the two ends of each of the heat-sinking components11and the inner lateral surface of the chamber21, with each of such heat-sinking components11provided with the respective air exhausting channel13being configured with a half-blocking form as illustrated in the fifth embodiment inFIG. 8D; in addition, the protrusion section116can be located between the two ends of the heat-sinking components11and the inner lateral surface of the chamber21, and each of the fourth board surfaces115is blocked at the upside of the two ends of each of the inner flow channels114such that the liquid water or gaseous water within the inner flow channel114can not directly contact the chamber21and the outer lid22from the two ends of each of the inner flow channels114, thereby eliminating the overflow and leakage issues at the joints; meanwhile, a large amount of liquid water or gaseous water can be retained in each of the inner flow channels114, and the liquid water is stably heated and evaporated in order to allow gaseous water to rapidly increase the internal pressure to achieve a high pressure.

Then, refer toFIGS. 14 and 15, in which a fifth embodiment for the integral structure configuration of the current stabilization and pressure boosting device for evaporator according to the present invention are shown. In the present embodiment, a predetermined space is configured between the two ends of each of the heat-sinking components11and the inner lateral surface of the chamber21, with each of such heat-sinking components11provided with the respective air exhausting channel13being configured with a half-blocking form as illustrated in the fifth embodiment inFIG. 8D; in addition, the protrusion section116can be located between the two ends of the heat-sinking components11and the inner lateral surface of the chamber21, and each of the fourth board surfaces115is blocked at the upside of the two ends of each of the inner flow channels114; also, the water injection channel12is disposed at the upside of each of the protrusion sections116, so that liquid water can sequentially pass through the water inlet23, the water injection channel12and the downside of each of the fourth board surfaces115into each of the inner flow channels114, and then circulate to the inside of the heat-sinking module1via each of the channels14such that the liquid water can be repeatedly evaporated into gaseous water after being heated. In this embodiment, the liquid water or gaseous water in each of the inner flow channels114will not directly contact the chamber21and the outer lid22from the two ends of each of the inner flow channels114, thus eliminating the overflow and leakage issues at the joints. At the same time, a large amount of liquid water or gaseous water can be retained in each of the inner flow channels114, in which the liquid water can be stably heated and evaporated to allow gaseous water to rapidly increase the internal pressure in order to form a high pressure; similarly, the liquid water can be stably heated and evaporated so that gaseous water can be quickly discharged by way of the air exhausting channel13thus stabilizing the internal water flow. Furthermore, refer toFIG. 16, in which a sixth embodiment for the integral structure configuration of the current stabilization and pressure boosting device for evaporator according to the present invention is shown.
