Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to an electronic product having an airflow-guiding device, and more particularly, to the electronic product effective using airflow for heat dissipation by preventing most of the airflow from being carried away by power supplies.  
       BACKGROUND OF THE INVENTION  
       [0002]     It is a common technique to use fans in various industrial equipments for heat dissipation, especially in widely used electronic products. With the increase of various applications, the number of electronic modules installed in one single electronic product also increases. Based on the design consideration of space, the electronic modules are usually stacked vertically in a housing of an electronic product. For example, there are quite many electronic modules (such as storage controllers) existing in an industrial computer or server. For the considerations of providing sufficient power to the electronic modules and providing backup power source, the electronic product such as an industrial computer or a server frequently needs installing two or more power supplies so as to satisfy the specific requirements of the aforementioned electronic products.  
         [0003]     On the other hand, since the number of the electronic modules is quite a few, a plurality of fan modules (such as four fan modules) have to be installed in the electronic product, thereby effectively resolving the heat-dissipation problem of the electronic modules. Generally speaking, the system fan modules in the electronic product are exposed to the ambiance so as to dissipate the heat to the ambiance, and each of the power supplies has a fan for dissipating its own heat, wherein the power supplies are located behind the system fan modules. When the fans of the power supplies and the system fan modules are working at the same time, the air pressures in the areas of power supplies are usually lower than those in the areas of other electronic modules, so that most of the airflow flows naturally into the power supplies after entering the housing of the electronic product from the ambiance, resulting in the other electronic modules lacking of airflow passing through. Thus, the heat-dissipation efficiency of the system fan modules decreases and the over-heat problem is seriously in the electronic modules. In other words, the fans of the power supplies carry away most of the airflow in the housing, thus resulting in the electronic modules failing to have effective heat-dissipation.  
         [0004]     Commonly, a conventional technique uses a wind-shielding partition designed with a plastic member to prevent airflow from flowing into the power supplies. However, the conventional plastic wind-shielding partition costs quite a lot of molding expense, and has the difficulty of design modification. Additionally, the mechanism for assembling the conventional wind-shielding partition with the housing of the electronic product is quite complicated, so that the disassembling and assembling steps cannot be briefly done, and also the wind-shielding partition is frequently damaged thereby. Moreover, the power supplies and the electronic modules all need proper amounts of airflow flowing therein, but it is very difficult to distribute airflow flexibly with the conventional plastic wind-shielding partition, i.e. the conventional plastic wind-shielding partition has poor airflow-guiding effect.  
         [0005]     Hence, there is a need to develop a housing of an electronic product having an air-flow guiding device, thereby promoting heat-dissipation efficiency; lowering the cost for fabricating partitions; lowering the difficulty level of processing a design change; flexibly distributing airflow to increase airflow-guiding effect; and simplifying the mechanism for assembling a metal plate partition with the housing of the electronic product, thus briefly disassembling and assembling the metal plate partition.  
       SUMMARY OF THE INVENTION  
       [0006]     It is an object of the present invention to provide an electronic product having an airflow-guiding device for lowering the cost for fabricating partitions and lowering the difficulty level of processing a design change.  
         [0007]     It is another object of the present invention to provide an electronic product having an airflow-guiding device for flexibly distributing airflow so as to increase airflow-guiding effect.  
         [0008]     It is another object of the present invention to provide an electronic product having an airflow-guiding device for simplifying the mechanism for assembling a metal plate partition with the housing of the electronic product, so as to briefly disassemble and assemble the metal plate partition.  
         [0009]     According to the aforementioned objects of the present invention, the present invention provides an electronic product having an airflow-guiding device.  
         [0010]     According to a preferred embodiment of the present invention, the electronic product having the airflow-guiding device comprises: a housing body, an electronic module group located in the housing body; at least one power supply, at least one system fan module, and at least one metal plate partition. The power supply is located in at least one passage between the electronic module group and the housing body. The system fan module is located on one end of the housing body and exposed to the ambience, and is used for introducing the ambient airflow into the housing body, thereby providing the heat-dissipation function for the electronic module group. The metal plate partition is installed on an air inlet of the passage facing towards the system fan module, thereby reducing the air flowing from the system fan module into the power supply.  
         [0011]     Further, the metal plate partition comprises: a partition main body, a first folded plate and a second folded plate. The partition main body has a first side and a second side opposite to each other, and has a first main surface and a second main surface opposite to each other. The first folded side and the second folded side are connected to the first side and the second side respectively, wherein the first folded plate is fixed to a module sidewall of the electronic module group, and the second folded plate is fixed to a housing sidewall of the housing body. There is a first folded plate angle between the first folded plate and the first main surface, and there is a second folded plate angle between the second folded plate and the second main surface, wherein the first folded plate angle and the second folded plate angle are greater than 0 degrees and smaller than 180 degrees.  
         [0012]     Further, the metal plate partition comprises: a fin plate connected to one side of the second folded plate opposite to the second side. There is a fin plat angle between the fin plate and a folded plate surface of the second folded plate facing towards the partition main body, wherein the fin plate angle is greater than 0 degrees and smaller than 180 degrees.  
         [0013]     Further, the metal plate partition comprises: at least one buffer element (such as a sponge pad), wherein the buffer element covers portions of two opposite sides of the partition main body adjacent to the first side and the second side, thereby allowing a proper amount of air to flow into the power supply.  
         [0014]     Further, the aforementioned first folded plate has: an opening located in the first folded plate, and a pair of shallow concaved portions. The opening is used to engage with a clipping structure located on the module sidewall. The shallow concaved portions are located respectively on two sides of the first folded plate adjacent to the partition main body, wherein one of the shallow concaved portions is used to kook up with another clipping structure located on the module sidewall.  
         [0015]     Further, the aforementioned second folded plate has a pair of deep concaved portions. The deep concaved portions are located on two sides of the second folded plate adjacent to the partition main body, wherein one of the deep concaved portions is used to engage with at least one guiding pillar located on the housing sidewall.  
         [0016]     Hence, with the application of the present invention, the fabrication cost of partitions and the difficulty level of processing a design change can be lowered; the airflow can distributed flexibly, thus enhancing the airflow-guiding effect; and the mechanism for assembling the metal plate partitions and the housing can be simplified, thereby briefly disassembling and assembling the metal plate partitions.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0022]     Referring to  FIG. 1 ,  FIG. 1  is a 3-D schematic diagram showing the assembly of system fan modules and an electronic product having an airflow-guiding device, according to a preferred embodiment of the present invention. The electronic product (such as an industrial computer or a server) of the present invention has a housing body  200 , and in the housing body  200 , there are an electronic module group  230 , at least one power supply (not shown; such as two power supplies), a plurality of system fan modules  300  (such as four system fan modules), and at least one metal plate partition (such as two metal plate partitions; metal plate partitions  100  and  400 ), wherein the electronic module group  230  is composed of a plurality of electronic modules (such as storage controllers; hard disk drives), and the electronic modules are generally installed in the central position of the housing body  200  with a vertically stacking pattern. A module partition  220   a  and a module partition  220   b  are installed between the power supplies and both sides of the electronic module group  230 , and the module partitions  220   a  and  220   b  are used for securing the electronic module group  230 . One power supply is located in a passage (not labeled) between the electronic module group  230  (or the module partition  220   a ) and a housing sidewall  210   a , and the other power supply is located in a passage (not labeled) between the electronic module group  230  (or the module partition  220   b ) and a housing sidewall  210   b , wherein each of the power supplies has a fan installed for dissipating the heat generated therefrom. The system fan modules  300  are located in one end of the housing body  200 , and are exposed to the ambience for dissipating the heat generated from the electronic product (ex: electronic module group  230 ) of the present invention. The metal plate partition  100  and the metal plate partition  400  are identical to each other in shape, size and structure, and are installed on air inlets of the aforementioned passages facing towards the system fan modules  300 , whereby the airflow coming from the system fan modules  300  can be prevented from entirely entering the power supplies, wherein the number of the metal plate partitions is the same as that of the power supplies, such as two. The aforementioned numbers of the metal plate partitions and the power supplies are merely stated as an example for explanation, and can be changed in accordance with actual needs, so that the present invention is not limited thereto.  
         [0023]     Since the metal plate partition  100  of the present invention are the same as the metal plate partition  400  thereof in shape, size and structure, and the method for combining the metal plate partition  100  with the housing sidewall  210   a  and the module partition  220   a  is also the same as that for combining the metal plate partition  400  with the housing sidewall  210   b  and the module partition  220   b . Therefore, only the metal plate partition  100  is used hereinafter for describing the present invention in detail.  
         [0024]     The metal plate partition  100  is composed of a partition main body  110 , and folded plates  120  and  130  connected to the partition main body  110 . While the metal plate partition  100  blocks an air inlet in front of the power supply, the airflow coming from the system fan modules  300  can be guided into the electronic module group  230 . However, the power supply still needs a proper amount of airflow passing through for heat dissipation. Hence, the present invention installs buffer elements  140   a  and  140   b  (such as sponge pads) on portions of two opposite sides of the partition main body  110  adjacent to the folded plates  120  and  130 , wherein the area of the buffer elements  140   a  and  140   b  covering the aforementioned opposite sides determines the gaps between the partition main body  110  and the top/bottom surfaces of the housing body  200 , after the upper cover of the housing is placed in position. If the area covered by the buffer elements  140   a  and  140   b  is larger, then the aforementioned gaps are smaller, and the amount of airflow entering the power supply is less accordingly. If the area covered by the buffer elements  140   a  and  140   b  is smaller, then the aforementioned gaps are bigger, and the amount of airflow entering the power supply is larger accordingly. The folded plate  120  is fixed to the module partition  220   a , and the folded plate  130  is fixed to the housing sidewall  210   a.    
         [0025]     Referring to  FIG. 2 ,  FIG. 2  is a 3-D schematic diagram showing the structure of a metal plate partition used in the preferred embodiment of the present invention. In the metal plate partition  100 , the partition main body  110  has two opposite sides  112  and  114 , and a lower main surface  116  and an upper main surface  118  that are opposite to each other. The folded plate  120  is connected to the side  112 , and there is a folded plate angle A between the folded plate  120  and the lower main surface  116 , wherein the folded plate angle A is greater than 0 degrees and smaller than 180 degrees. The folded plate  130  is connected to the side  114 , and there is a folded plate angle B between the folded plate  130  and the lower main surface  118 , wherein the folded plate angle. B is greater than 0 degrees and smaller than 180 degrees. The folding direction of the folded plate  120  is opposite to that of the folded plate  130 . A fin plate  136  is connected to one side of the folded plate  130  opposite to the side  114 , and the fin plate  136  is used for conveniently disassembling the folded plate  130 , wherein there is a fin plate angle C between the fin plate  136  and a folded plate surface  138  of the folded plate  130  facing towards the partition main body  110 , and the fin plate angle C is greater than 0 degrees and smaller than 180 degrees.  
         [0026]     Referring to  FIG. 2  and  FIG. 3A  continuously,  FIG. 3A  is a 3-D locally-enlarged schematic view showing the metal plate partition combined with a module sidewall, according to the preferred embodiment of the present invention. Such as shown in detail A, the folded plate  120  has an opening  122  and a pair of shallow concaved portions  124   a  and  124   b , wherein the opening  122  is located in the folded plate  120  for engaging with a clipping structure  222  located on the module partition  220   a , and the shallow concaved portions  124   a  and  124   b  are located on two sides of the folded plate  120  adjacent to the partition main body  110 , wherein one of the shallow concaved portions  124   a  and  124   b  is used to engage with a clipping structure  224  located on the module partition  220   a.    
         [0027]     Referring to  FIG. 2  and  FIG. 3B  continuously,  FIG. 3B  is a 3-D locally-enlarged schematic view showing the metal plate partition combined with a sidewall of the housing body, according to the preferred embodiment of the present invention. Such as shown in detail B, the folded plate  130  has a pair of deep concaved portions  134   a  and  134   b . The deep concaved portions  134   a  and  134   b  are located respectively on two sides of the folded plate  130  adjacent to the partition main body  110 , wherein one of the deep concaved portions  134   a  and  134   b  (such as the deep concaved portion  134   b ) is used to engage with at least one guiding pillar  212  located in the housing sidewall  210   a . The number of the guiding pillars  212  can be such as two, and the structure thereof can be similar to a screw.  
         [0028]     One of the features of the present invention is to use metal plate material for fabricating an airflow-guiding device (the metal plate partitions  100  and  400 ). Using the metal plate material has the advantages of no molding expense needed and easy processing, and only a pressing method is needed for processing the metal plate material, so as to complete the fabrication of the airflow-guiding device for the present invention. In comparison to the conventional plastic wind-shielding partition, the airflow-guiding device of the present invention can be easily processed with a design change. Further, since the present invention uses the guiding pillars, the clipping structures, the concaved portions and the openings to fix the metal plate partitions to the housing body and the module partitions, the metal plate partitions can be disassembled or assembled easily and only by moving the fin plates of the metal plate partitions without using other screw elements.  
         [0029]     It can be known from the aforementioned preferred embodiment of the present invention, the advantages of applying the present invention are: greatly reducing the fabrication cost of partitions, and lowering the difficulty level of processing a design change; effectively and flexibly distributing airflow, thus greatly enhancing the airflow-guiding effect; and greatly simplifying the mechanism for assembling the metal plate partitions and the housing, thereby briefly disassembling and assembling the metal plate partitions.  
         [0030]     As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrated of the present invention rather than limiting of the present invention. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure.
