[0001] The utility model relates to a water cooling plate, in particular to a water cooling plate with two heat-conducting square tubes connected. BACKGROUND

[0002] The operation of an electronic device is accompanied by the generation of a large amount of heat energy. If the heat energy cannot be effectively removed, the internal electronic components will overheat, resulting in problems such as functional failure or shutdown. Therefore, the electronic device usually has a corresponding heat dissipation system to ensure that the operation of the components does not exceed the default operating temperature range. Especially for high-performance electronic devices, a liquid cooling heat dissipation system such as a water cooling plate is usually used to provide better heat dissipation effect.

However, the water cooling plate made by CNC machining has high manufacturing cost, and the volume of the heat exchange flow channel is small and difficult to meet the demand for heat dissipation efficiency. Therefore, how to reduce the manufacturing cost of the water cooling plate and improve the heat dissipation efficiency is one of the problems that researchers should solve. SUMMARY

[0053] The water-cooled plate 10 of this embodiment includes two cold plate bodies 11, two elastic fasteners 12, two flow dividers 13, an inlet pipe 14, an outlet pipe 15, and a connecting pipe 16. Each cold plate body 11 includes a first heat-conducting square tube 111, a second heat-conducting square tube 112, a top plate 113, and a bottom plate 114.

[0054] The first and second heat-conductive square tubes 111 and 112 are, for example, copper tubes. In detail, the material of the first heat-conductive square tube 111 and the material of the second heat-conductive square tube 112 are, for example, phosphorus deoxidized copper (TP2). The first heat-conductive square tube 111 and the second heat-conductive square tube 112 are, for example, arranged side by side and thermally coupled. In this way, heat conduction between the first heat-conductive square tube 111 and the second heat-conductive square tube 112 can be achieved. The so-called thermal coupling means thermal contact or connection through other heat-conductive medium. The first heat-conductive square tube 111 and the second heat-conductive square tube 112 are used to contain a cooling liquid (not shown). The cooling liquid is, for example, water or refrigerant.

[0055] The first heat-conductive square tube 111 has a first flow channel 1111, a fluid inlet 1112, and a first fluid communication port 1113. The fluid inlet 1112 and the first fluid communication port 1113 communicate with the first flow channel 1111. The second heat-conductive square tube 112 is connected to the first heat-conductive square tube 111. For example, the second heat-conductive square tube 112 is connected to the first heat-conductive square tube 111 by brazing, but is not limited thereto. The second heat-conductive square tube 112 has a second flow channel 1121, a second fluid communication port 1122, and a fluid outlet 1123. The fluid outlet 1123 and the second fluid communication port 1122 communicate with the second flow channel 1121. The first flow channel 1111 and the second flow channel 1121 are communicated through the first fluid communication port 1113 and the second fluid communication port 1122.

[0056] In the present embodiment, the cross section of the first flow channel 1111 parallel to the fluid inlet 1112 and the cross section of the second flow channel 1121 parallel to the fluid outlet 1123 are, for example, rectangular. In addition, the first heat-conductive square tube 111 and the second heat-conductive square tube 112 are at least partially sandwiched between the top plate 113 and the bottom plate 114. The material of the top plate 113 is, for example, cold-rolled steel plate (SPCC), and the material of the bottom plate 114 is, for example, copper (such as Cu1100). In addition, the top plate 113 is connected to the first heat-conductive square tube 111 and the second heat-conductive square tube 112 by, for example, soft soldering, and the bottom plate 114 is connected to the first heat-conductive square tube 111 and the second heat-conductive square tube 112 by, for example, hard soldering.

[0057] Two elastic buckle members 12 are respectively arranged on the two top plates 113 to press against the two cold plate bodies 11, and are used to buckle on a plate body (not shown) provided with a heat source (not shown), so that the two cold plate bodies 11 are thermally coupled to the heat source. In detail, each elastic buckle member 12 includes a pressing portion 121 and two buckle portions 122. The two buckle portions 122 are connected to the opposite sides of the pressing portion 121. The pressing portion 121 presses against the top plate 113, so that the two cold plate bodies 11 are more tightly thermally coupled to the heat source. The two buckle portions 122 are used to buckle on the plate body to fix the two cold plate bodies 11. The material of the elastic buckle member 12 is, for example, stainless steel (such as SUS301 1 / 2H).

[0058] The diverter 13 is disposed on one side of the first heat-conducting square tube 111 and the second heat-conducting square tube 112. The diverter 13 is made of copper (e.g., Cu1100), for example, and is connected to the first heat-conducting square tube 111 and the second heat-conducting square tube 112 by, for example, brazing. The diverter 13 has a diverter inlet 131 and a diverter outlet 132. The fluid inlet 1112 of one of the two cold plate bodies 11 is connected to the liquid inlet pipe 14 via the diverter inlet 131. The fluid outlet 1123 of the other of the two cold plate bodies 11 is connected to the liquid outlet pipe 15 via the diverter outlet 132. The fluid outlet 1123 of one of the two cold plate bodies 11 and the fluid inlet 1112 of the other of the two cold plate bodies 11 are located between the fluid inlet 1112 of one of the two cold plate bodies 11 and the fluid outlet 1123 of the other of the two cold plate bodies 11, and are respectively connected via the connecting flow pipe 16. The material of the liquid inlet pipe 14 and the liquid outlet pipe 15 is, for example, stainless steel (such as SUS316L).

[0059] In this embodiment, the water-cooled plate 10 may further include two first shielding members 17. The first heat-conducting square tube 111 has a first opening 1114 on a side away from the fluid inlet 1112. The first opening 1114 is connected to the first flow channel 1111. The second heat-conducting square tube 112 has a second opening 1124 on a side away from the fluid outlet 1123. The second opening 1124 is connected to the second flow channel 1121. The first shielding member 17 shields the first opening 1114 and the second opening 1124. The material of the first shielding member 17 is, for example, copper (such as Cu1100), and the first shielding member 17 is connected to the first heat-conducting square tube 111 and the second heat-conducting square tube 112 by, for example, brazing.

[0060] In this embodiment, the water-cooled plate 10 may further include a second shielding member 18. The second heat-conducting square tube 112 has a third opening 1125 on one side away from the second fluid connection port 1122. The third opening 1125 is connected to the second flow channel 1121. The second shielding member 18 shields the third opening 1125. The material of the second shielding member 18 is, for example, copper (such as Cu1100), and the second shielding member 18 is connected to the second heat-conducting square tube 112, for example, by welding. In addition, the top plate 113 may further have a notch 1131. The notch 1131 is used to make way for the third opening 1125 and the second shielding member 18. By providing the first shielding member 17 and the second shielding member 18, the first flow channel 1111 and the second flow channel 1121 can be closed so that the first flow channel 1111 and the second flow channel 1121 are in a closed state.

[0061] In this embodiment, the water-cooling plate 10 is provided with a first heat-conducting square tube 111 and a second heat-conducting square tube 112 in the form of a square column, and the first heat-conducting square tube 111 and the second heat-conducting square tube 112 are connected by welding. Compared to water-cooling plates manufactured using CNC machining, this not only reduces manufacturing costs but also increases the volume of the first flow channel 1111 and the second flow channel 1121 used for heat exchange. This improves the heat dissipation efficiency of the water-cooling plate 10.

[0062] Furthermore, when the manufacturer wishes to produce water cooling plates 10 of different sizes, they only need to adjust the width and height of the first heat conducting square tube 111 and the second heat conducting square tube 112. In other words, the structural design of the water cooling plate 10 of this embodiment is highly flexible.

[0063] In this embodiment, the number of cold plate bodies 11, the number of elastic fasteners 12, and the number of diverter members 13 is two, and the number of connecting flow tubes 16 is only one, but this is not limiting. In other embodiments, the number of cold plate bodies, the number of elastic fasteners, and the number of diverter members may also be only one, and no connecting flow tubes may be provided. In other words, within a single cold plate body, the fluid inlet communicates with the liquid inlet flow tube via the diverter inlet, and the fluid outlet communicates with the diverter outlet via the liquid outlet flow tube.

[0064] Alternatively, the number of cold plate bodies, the number of elastic fasteners, and the number of flow diverters may be three or more, and the number of connecting flow tubes may be two or more. Specifically, the fluid inlet of one of the outermost two cold plate bodies is connected to the liquid inlet flow tube via the diverter inlet, the fluid outlet of the other of the outermost two cold plate bodies is connected to the liquid outlet flow tube via the diverter outlet, and the remaining fluid outlets are connected to the fluid inlets via the connecting flow tubes.

[0065] See also Figure 5 In this embodiment, when coolant flows from the liquid inlet pipe 14 into the first heat-conducting square tube 111 of one of the two cold plate bodies 11, the coolant first flows along direction A from the diversion inlet 131 through the fluid inlet 1112 into the first flow channel 1111. The coolant then flows along direction B within the first flow channel 1111. The coolant then flows from the first heat-conducting square tube 111 into the second heat-conducting square tube 112. Specifically, the coolant flows along direction C from the first flow channel 1111 through the first fluid communication port 1113 and the second fluid communication port 1122 into the second flow channel 1121.

[0066] Next, the coolant flows in direction D within the second flow channel 1121. The coolant then flows in direction E from the fluid outlet 1123 through the diverter outlet 132 into the connecting flow pipe 16. The coolant then flows through the connecting flow pipe 16 into the other side of the second cold plate body 11. After flowing through the first and second heat-conducting square tubes 111 and 112 as described above, the coolant flows through the fluid outlet 1123 and diverter outlet 132 of the second heat-conducting square tube 112 and out to the liquid outlet flow pipe 15. At this point, the coolant absorbs and removes heat from the heat source, and the next cooling cycle begins.

[0067] According to the above embodiment, the water-cooling plate is provided with a first heat-conducting square tube and a second heat-conducting square tube in the shape of a square column, and the first heat-conducting square tube and the second heat-conducting square tube are connected by welding. Therefore, compared with water-cooling plates manufactured by CNC machining, the manufacturing cost is lower and the volume of the first and second flow channels used for heat exchange can be increased. In this way, the heat dissipation efficiency of the water-cooling plate can be improved.

[0068] Furthermore, when manufacturers want to produce water cooling plates of different sizes, they only need to adjust the width and height of the first and second heat conducting square tubes. In other words, the structural design of the water cooling plate of this embodiment is highly flexible.

[0069] Although the present invention is disclosed above with reference to the aforementioned embodiments, they are not intended to limit the present invention. Any person skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the claims attached to this specification.
