Description

TECHNICAL FIELD

[0001] The utility model relates to the field of liquid cooling heat dissipation, especially a liquid cooling plate. BACKGROUND

[0002] With the vigorous development of electronic technology, various electronic devices and electronic equipment develop towards high efficiency and thinness, thereby generating a large amount of heat energy when operating, so that the traditional air cooling (gas cooling) or only relying on fin group to dissipate heat cannot meet the heat dissipation demand, therefore, the liquid cooling radiator such as liquid cooling head, liquid cooling plate or liquid cooling row gradually becomes the mainstream as the main heat dissipation means.

[0003] However, the existing liquid cooling plate is limited by its volume, so the flow path of the cooling liquid therein is short, that is, the residence time of the cooling liquid in the liquid cooling plate is short, so that the heat energy that the cooling liquid can absorb is limited and does not affect the heat dissipation effect of the liquid cooling plate. In addition, when the cooling liquid is heated to reach the saturation temperature, the cooling liquid will vaporize to generate bubbles, thereby reducing the heat transfer number and affecting the flow of the remaining liquid cooling liquid.

[0004] In view of this, the present inventors have made great efforts to solve the above problems by means of careful research and application of theories, which is the improvement goal of the present inventors. SUMMARY

[0008] In an embodiment of the utility model, the retaining wall and each side wall extend from the second plane to abut against the first plane.

[0009] In an embodiment of the utility model, the cover shell further has a low wall, the low wall extends from the second plane and does not contact the first plane, the low wall connects each side wall and is oppositely arranged with the retaining wall so that the main heat source is correspondingly located between the retaining wall, the low wall and each side wall.

[0012] In an embodiment of the utility model, the cover shell further has a low wall, the low wall connects each side wall and is oppositely arranged with the retaining wall so that the main heat source is correspondingly located between the retaining wall, the low wall and each side wall, each second turbulence support column extends from the second plane to abut against part of the first turbulence support columns, and the retaining wall, the low wall and each side wall extend from the second plane to abut against the remaining first turbulence support columns.

[0013] In an embodiment of the utility model, the cover shell further has a pair of connecting walls, each connecting wall extends from the second plane and is connected between each side wall and the second surrounding wall.

[0014] In an embodiment of the utility model, the bottom shell has a plurality of first turbulence support columns, the cover shell has a plurality of second turbulence support columns, each first turbulence support column extends from the first plane, each second turbulence support column extends from the second plane to abut against part of the first turbulence support columns, and the retaining wall and each side wall extend from the second plane to abut against the remaining first turbulence support columns.

[0015] In an embodiment of the utility model, the bottom shell has a plurality of first turbulence support columns, each first turbulence support column extends from the first plane to abut against the second plane.

[0016] In an embodiment of the utility model, the cover shell has a plurality of second turbulence support columns, each second turbulence support column extends from the second plane to abut against the first plane.

[0019] In an embodiment of the present application, the bottom shell has a porous layer, which is located in the first container groove corresponding to the position of the main heat source and surrounded by the baffle wall and the side walls.

[0020] In an embodiment of the present application, the porous layer is a mesh structure and has a plurality of perforations.

[0021] In an embodiment of the present application, the porous layer is composed of a plurality of fin structures or a plurality of columnar structures.

[0022] In an embodiment of the present application, the length of each side wall is less than or equal to the length of the porous layer.

[0023] In an embodiment of the present application, the number of liquid inlets and the number of liquid outlets are both multiple and are arranged in pairs.

[0024] The liquid cooling plate of the present application, since the baffle wall is located between the liquid inlet and the liquid outlet, and the connecting line between the liquid inlet and the liquid outlet intersects the baffle wall, the baffle wall can block the cooling liquid from flowing directly from the liquid inlet to the liquid outlet. In addition, each side wall is connected to the baffle wall and extends away from the liquid inlet, so that each side wall can extend the flow path of the cooling liquid, thereby increasing the time for the cooling liquid to absorb heat energy, thereby effectively increasing the average temperature of the cooling liquid to improve the heat dissipation efficiency of the main heat source and each auxiliary heat source. Furthermore, when the cooling liquid absorbs the heat energy of the main heat source and each auxiliary heat source, it will evaporate into bubbles, so the baffle wall and each side wall located in the shell can also limit the bubbles above the main heat source, thereby avoiding the bubbles affecting the flow of the cooling liquid.

[0061] The detailed description and technical content of this utility model will be explained below with reference to the accompanying drawings. However, the drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0062] The utility model provides a liquid cooling plate for attaching on at least one main heat source (not shown in the figure) and a plurality of auxiliary heat sources (not shown in the figure), and the liquid cooling plate can be used for flowing through a cooling liquid (not shown in the figure), so as to cool and radiate the main heat source and each auxiliary heat source. It should be noted that the main heat source refers to an object that generates more heat energy than each auxiliary heat source. For example, the main heat source can be a chip, and each auxiliary heat source is a general electronic component or electronic component, but the utility model is not limited thereto. In addition, the arrows in each figure are used to briefly show the flow direction of the cooling liquid, but it is not completely limited that the cooling liquid can only flow according to the arrows shown in each figure, and this is stated. Please refer to Figures 1 to 4 The first embodiment of the liquid cooling plate of the utility model includes a bottom shell 10 and a cover shell 20. In this embodiment, the number of the main heat source is one, but the utility model is not limited thereto.

[0063] In this embodiment, the bottom shell 10 is made of copper or aluminum or other metal with good thermal conductivity, but the utility model is not limited thereto. The bottom shell 10 has a first plane 11, a first surrounding wall 12 and a first container groove 13. The first surrounding wall 12 surrounds the periphery of the first plane 11 and cooperates with the first plane 11 to form the first container groove 13. Specifically, the bottom shell 10 in this embodiment is a rectangular shell, so the first plane 11 is rectangular, and the first surrounding wall 12 is a hollow rectangular frame, so that the first container groove 13 is a rectangular groove, but the shapes of the first plane 11, the first surrounding wall 12 and the first container groove 13 can be adjusted accordingly according to different requirements.

[0064] In the present embodiment, the cover 20 is made of metal with good thermal conductivity such as copper or aluminum, but the present application is not limited thereto. The cover 20 has a second plane 21, a second surrounding wall 22, a second container groove 23, an inlet 201, an outlet 202, a barrier wall 24, and a pair of side walls 25. The second surrounding wall 22 surrounds the periphery of the second plane 21 to form the second container groove 23 together with the second plane 21. Specifically, the cover 20 in the present embodiment is also a rectangular shell, so the second plane 21 is rectangular, and the second surrounding wall 22 is a hollow rectangular frame, so that the second container groove 23 is a rectangular groove, but the shapes of the second plane 21, the second surrounding wall 22, and the second container groove 23 can be adjusted accordingly according to different needs. The cover 20 is connected and fixed to the bottom shell 10, so that the first container groove 13 and the second container groove 23 form a chamber together (not labeled in the figure). Specifically, the first container groove 13 of the bottom shell 10 and the second container groove 23 of the cover 20 are oppositely arranged and communicate with each other to form a chamber together, and the bottom shell 10 and the cover 20 are fixed by welding, but the present application is not limited thereto. In the present embodiment, the inlet 201 corresponds to one side of the main heat source, and the outlet 202 corresponds to the upper side of the main heat source, i.e. the outlet 202 corresponds to the position between the barrier wall 24 and the side walls 25. The barrier wall 24 and the side walls 25 extend from the second plane 21. The barrier wall 24 is located between the inlet 201 and the outlet 202. Specifically, the connecting line between the inlet 201 and the outlet 202 intersects the barrier wall 24, i.e. the barrier wall 24 can block the cooling liquid from flowing directly from the inlet 201 to the outlet 202 in a straight line. Each side wall 25 is connected to the barrier wall 24 and extends away from the inlet 201, so that the main heat source corresponds to the position between the barrier wall 24 and the side walls 25.

[0065] Therefore, since the barrier wall 24 is located between the inlet 201 and the outlet 202 and the connecting line between the inlet 201 and the outlet 202 intersects the barrier wall 24, the barrier wall 24 can block the cooling liquid from flowing directly from the inlet 201 to the outlet 202 in a straight line, as shown in Figure 3 In addition, by connecting each side wall 25 to the barrier wall 24 and extending away from the inlet 201, each side wall 25 can extend the flow path of the cooling liquid, so that the cooling liquid increases the time of absorbing heat energy, thereby effectively increasing the average temperature of the cooling liquid to improve the heat dissipation efficiency of the main heat source and each auxiliary heat source, as shown in Figure 3 Furthermore, when the cooling liquid absorbs the heat energy of the main heat source and each auxiliary heat source, it will evaporate into bubbles, so the barrier wall 24 and the side walls 25 of the cover 20 can also limit the bubbles above the main heat source, thereby avoiding the influence of the bubbles on the flow of the cooling liquid.

[0066] In the present embodiment, the barrier wall 24 and the side walls 25 extend from the second plane 21 to abut the first plane 11, that is, the barrier wall 24 and the side walls 25 both extend from the second container 23 to the first container 13. In this way, the barrier wall 24 and the side walls 25 can completely block the cooling liquid, so that the cooling liquid can only pass through the gaps between the side walls 25 and the first or second surrounding wall 12 or 22, thereby avoiding the cooling liquid flowing directly from the liquid inlet 201 to the liquid outlet 202 in a straight line, and effectively extending the flow path of the cooling liquid to improve the heat dissipation efficiency, as shown in Figure 4

[0067] Further, the cover 20 in the present embodiment also has a low wall 26. The low wall 26 is connected to the side walls 25, and the low wall 26 is arranged opposite to the barrier wall 24 so that the main heat source is located between the barrier wall 24, the low wall 26 and the side walls 25. Specifically, the barrier wall 24, the low wall 26 and the side walls 25 collectively form a rectangle so that the main heat source is located in the rectangle. The low wall 26 extends from the second plane 21 and does not contact the first plane 11. In other words, there is a gap between the low wall 26 and the first plane 11 for the cooling liquid to flow through. In the present embodiment, the extension height of the low wall 26 is approximately the same as the extension height of the second surrounding wall 22, but the present application is not limited thereto. In this way, the cooling liquid can only flow through the gaps between the side walls 25 and the first or second surrounding wall 12 or 22 due to the blocking of the barrier wall 24 and the side walls 25, and because of the blocking of the low wall 26, the cooling liquid can only enter between the barrier wall 24, the low wall 26 and the side walls 25 from the bottom of the chamber (i.e. at the first container 13), and after cooling the main heat source, it exits from the liquid outlet 202, and the arrangement of the low wall 26 can further limit the gas bubbles formed after the cooling liquid vaporizes, thereby facilitating the smooth flow of the cooling liquid, as shown in Figure 4

[0068] In addition, the bottom shell 10 has a plurality of first turbulence support columns 14, and the cover 20 has a plurality of second turbulence support columns 27. In the present embodiment, each first turbulence support column 14 extends from the first plane 11 and is arranged in a matrix, and each second turbulence support column 27 extends from the second plane 21 to abut each first turbulence support column 14. In this way, each first turbulence support column 14 and each second turbulence support column 27 not only can support the bottom shell 10 and the cover 20 and increase the structural strength, but also can form a turbulence effect on the cooling liquid to ensure that the cooling liquid can flow uniformly through the chamber to improve the heat dissipation efficiency. However, the present application is not limited thereto. For example, as shown in Figure 14 ​​As shown, the bottom shell 10 has a plurality of first spoiler support columns 14, and each first spoiler support column 14 extends from the first plane 11 to abut the second plane 21, so the cover shell 20 does not need to have a plurality of second spoiler support columns 27, which can also play the role of supporting, increasing structural strength and improving the spoiler effect. In addition, as shown in Figure 15 As shown, the cover shell 20 has a plurality of second spoiler support columns 27, and each second spoiler support column 27 extends from the second plane 21 to abut the first plane 11, so the bottom shell 10 does not need to have a plurality of first spoiler support columns 14, which can also play the role of supporting, increasing structural strength and improving the spoiler effect.

[0069] Further, the bottom shell 10 has a porous layer 15. The porous layer 15 is arranged in the first container 13 corresponding to the position and area of the main heat source, and is surrounded by the retaining wall 24, the side walls 25 and the dwarf wall 26. The porous layer 15 has a plurality of flow channels (not shown), a plurality of perforations (see Figure 14 ) or a plurality of gaps (see Figure 15 ), which can be formed by various structures such as a capillary structure by powder sintering, a micro-fin group formed by shoveling, a plurality of fin structures by welding (such as Figure 4 ), a plurality of columnar structures (such as Figure 15 ) or a metal mesh structure (such as Figure 14 ), as long as the cooling liquid can be divided into smaller liquid beads through the flow channels, perforations or gaps. In this way, by cutting the cooling liquid into smaller liquid beads, the heat capacity ratio can be effectively reduced, and the liquid beads can be more easily vaporized, thereby effectively improving the heat dissipation efficiency. Through the inventor's experiments, the thickness of the porous layer 15 is less than or equal to 200 microns (µm), thereby achieving the best liquid bead cutting effect. In this embodiment, the length of each side wall 25 is greater than the length of the porous layer 15, that is, the porous layer 15 is located within the surrounding range of the retaining wall 24, the side walls 25 and the dwarf wall 26, but the present application is not limited thereto.

[0070] Please continue to refer to Figures 5 to 7 As shown, the second embodiment of the liquid cooling plate of the present application is different from the first embodiment in the number of first spoiler support columns 14 and the extension height of the retaining wall 24 and the side walls 25, which will be described in detail as follows.

[0071] In this embodiment, the base shell 10 also has a plurality of first turbulence support columns 14, and the cover shell 20 also has a plurality of second turbulence support columns 27, but the number of the first turbulence support columns 14 is greater than the number of the second turbulence support columns 27. Each first turbulence support column 14 extends from the first plane 11 and is arranged in a matrix. Each second turbulence support column 27 extends from the second plane 21 to abut part of the first turbulence support columns 14. The remaining first turbulence support columns 14 are arranged around the main heat source and the porous layer 15. The barrier wall 24, the side walls 25, and the dwarf walls 26 all extend from the second plane 21 to abut the remaining first turbulence support columns 14. Therefore, the barrier wall 24 and the side walls 25 in this embodiment do not completely block the passage of the cooling liquid through the chamber, that is, the cooling liquid can flow through the space below the barrier wall 24 and the side walls 25 (i.e., the bottom of the chamber), as well as the space between the side walls 25 and the first surrounding wall 12 or the second surrounding wall 22, as shown in Figure 6 and Figure 7 .

[0072] Please also refer to Figures 8 to 10 , the third embodiment of the liquid cooling plate of the present application, the main difference between the second embodiment is that the number of the first turbulence support columns 14, the length of the side walls 25, the configuration of the pair of connecting walls 28 instead of the dwarf walls 26, and the position of the outlet 202, as follows.

[0073] In this embodiment, the cover shell 20 has a pair of connecting walls 28 instead of the dwarf walls 26. Each connecting wall 28 extends from the second plane 21 and is connected between the side wall 25 and the second surrounding wall 22. In other words, the barrier wall 24, the side walls 25, and the connecting walls 28 collectively approximately form an inverted "Ω" shape. And the barrier wall 24, the side walls 25, and the connecting walls 28 in this embodiment are all located between the inlet 201 and the outlet 202, that is, the outlet 202 in this embodiment is not located above the main heat source and the porous layer 15.

[0074] In the present embodiment, the bottom shell 10 also has a plurality of first turbulence support columns 14, and the cover shell 20 also has a plurality of second turbulence support columns 27, but the number of the first turbulence support columns 14 is greater than the number of the second turbulence support columns 27. Each first turbulence support column 14 extends from the first plane 11 and is arranged in a matrix, and the rest of the first turbulence support columns 14 are arranged around a part of the main heat source and a part of the porous layer 15 corresponding to the barrier wall 24 and each side wall 25. The barrier wall 24 and each side wall 25 are extended from the second plane 21 to abut the rest of the first turbulence support columns 14. Therefore, the barrier wall 24 and each side wall 25 in the present embodiment also do not completely block the passage of the cooling liquid through the chamber, but because each connecting wall 28 is connected between each side wall 25 and the second surrounding wall 22, the cooling liquid can only flow through from below the barrier wall 24, each side wall 25 and each connecting wall 28 (i.e. the bottom of the chamber), and then exit from the liquid outlet 202 after passing completely above the main heat source and the porous layer 15, as shown in Figure 9 and Figure 10 .

[0075] Further, the length of each side wall 25 in the present embodiment is less than or equal to the length of the porous layer 15, so that the cooling liquid can spread towards the top of the chamber after flowing through below each side wall and each connecting wall 28, thereby increasing the flow rate of the cooling liquid and improving the heat dissipation efficiency. In addition, because the barrier wall 24, each side wall 25 and each connecting wall 28 in the present embodiment are located between the liquid inlet 201 and the liquid outlet 202, it can also avoid some of the cooling liquid remaining above the main heat source and the porous layer 15.

[0076] It should be noted that the liquid cooling plate of the present application is not limited to cooling and dissipating heat for a single main heat source, but can also simultaneously cool and dissipate heat for multiple main heat sources according to different needs.

[0077] For example, referring to Figure 11 , the fourth embodiment of the liquid cooling plate of the present application, the main difference between the first embodiment is that the number of barrier walls 24, each side wall 25, each low wall 26, the porous layer 15, the liquid outlet 202 and the main heat source is twice that of the first embodiment. Specifically, each of the main heat sources in the present embodiment is arranged in a transverse direction, and the liquid inlet 201 and each liquid outlet 202 are also arranged in a transverse direction. Each barrier wall 24, each side wall 25, each low wall 26 and each porous layer 15 is divided into two groups on average, and is configured in the manner of the first embodiment corresponding to each main heat source. In this way, multiple main heat sources can be cooled and dissipated simultaneously under the technical concept of the present application.

[0078] Again, please continue to refer to Figure 12As shown, the main difference between the fifth embodiment of the liquid cooling plate of the utility model and the fourth embodiment is that the number of the retaining walls 24, the side walls 25 and the low walls 26 is the same as that of the first embodiment. Specifically, the number of the liquid outlets 202 in the embodiment is still two and each corresponds to a main heat source arranged in the transverse direction, but each side wall 25 is connected to the retaining wall 24 and extends in the transverse direction beyond each main heat source, that is, each main heat source and each porous layer 15 are completely located between the surrounding ranges of the retaining wall 24, the side wall 25 and the low wall 26. In this way, multiple main heat sources can be cooled and radiated at the same time under the technical concept of the utility model, and the structure is relatively simple compared with the fourth embodiment.

[0079] In addition, the utility model is not limited to a single liquid inlet 201, that is, the number of the liquid inlet 201 and the number of the liquid outlet 202 can be multiple and matched with each other. For example, please refer to Figure 13 As shown, the sixth embodiment of the utility model, the main difference between the fourth embodiment is that the number of the liquid inlet 201 and the arrangement of each retaining wall 24, each side wall 25 and each low wall 26. Specifically, the retaining wall 24, the side wall 25 and the low wall 26 corresponding to each main heat source in the embodiment are arranged opposite to each other, and each liquid inlet 201 is located on the side of the corresponding retaining wall 24 away from each main heat source. Therefore, the cooling liquid flowing from each liquid inlet 201 will sequentially bypass the corresponding retaining wall 24, the side wall 25 and the low wall 26 to the corresponding porous layer 15 and then leave from the corresponding liquid outlet 202. In this way, multiple liquid inlets 201 can be used to cool and radiate each main heat source at the same time, and compared with the fourth embodiment, it can be applied to radiate each main heat source that generates more heat.

[0080] The liquid cooling plate of the utility model, because the retaining wall 24 is located between the liquid inlet 201 and the liquid outlet 202, and the connecting line between the liquid inlet 201 and the liquid outlet 202 intersects the retaining wall 24, so the retaining wall 24 can block the cooling liquid from flowing directly from the liquid inlet 201 to the liquid outlet 202. In addition, each side wall 25 is connected to the retaining wall 24 and extends away from the liquid inlet 201, so each side wall 25 can extend the flow path of the cooling liquid, so that the cooling liquid increases the time of absorbing heat energy, thereby effectively increasing the average temperature of the cooling liquid to improve the heat dissipation efficiency of the main heat source and each auxiliary heat source. Furthermore, when the cooling liquid absorbs the heat energy of the main heat source and each auxiliary heat source, it will evaporate into bubbles, so the retaining wall 24 and each side wall 25 located in the cover 20 can limit the bubbles above the main heat source, thereby avoiding the bubbles affecting the flow of the cooling liquid.

[0081] To sum up, the foregoing disclosed content of the utility model is for letting the technical personnel of the field can clearly understand the technical content of the utility model and is according to implementation, and is not intended to limit the patent protection scope of the utility model. In addition, the utility model can of course have other unlisted various embodiments, and the skilled person in the art should evolve various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and deformations should all belong to the protection scope of the patent applied by the utility model.
