Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and further to a liquid cooling module and liquid cooling system. Background Technology

[0002] In existing technologies, liquid cooling systems are widely used in high-power electronic devices or server equipment. They typically involve circulating coolant in pipes and sequentially flowing through multiple water cooling heads to remove heat generated by various heat-generating components. Generally, liquid cooling systems with multiple water cooling heads mostly adopt a series flow channel design, allowing the coolant to pass through each water cooling head sequentially from the front to the back to achieve overall heat dissipation.

[0003] However, in a series liquid cooling architecture, the coolant absorbs a significant amount of heat as it flows through the front water block, resulting in a substantial temperature increase by the time it reaches the rear water block. This reduces the heat dissipation efficiency of the rear water block and causes uneven overall heat dissipation. Furthermore, in terms of fluid distribution, after flowing through multiple water blocks, the coolant may experience insufficient flow to the rear water block due to pressure loss or increased flow resistance, further affecting its cooling effect and potentially causing localized overheating. Summary of the Invention

[0010] In some embodiments, the first chamber is provided with a first cold inlet and a first hot inlet, the first cold inlet being connected to the first cold water channel, and the first hot inlet being connected to the first hot water channel and the first water pump chamber.

[0011] In some embodiments, the first body has a first annular groove on the periphery of the first chamber, and the first annular groove is connected to the first cold port.

[0025] In one embodiment, refer to the appendix to the specification. Figure 1This is a three-dimensional schematic diagram of the liquid cooling module of this application. This application provides a liquid cooling module 1, including a first water-cooling head 10, a second water-cooling head 20, a water storage tank assembly 30, and multiple connecting pipes 40. The water storage tank assembly 30 is disposed between the first water-cooling head 10 and the second water-cooling head 20 through the connecting pipes 40, thereby forming a cooling circulation structure with fluid buffering and redistribution functions. Furthermore, the first water-cooling head 10 and the second water-cooling head 20 are used to contact and exchange heat with the heat-generating elements. The coolant is water or other liquids with thermal conductivity, such as ethylene glycol mixtures, but is not limited thereto. The liquid cooling module 1 is described in more detail below.

[0026] Please refer to another source. Figures 2 to 5 These figures represent an exploded perspective view of the first water-cooling head of this application, a perspective view of the first body from two sides, and a usage diagram of the liquid-cooling module. The first water-cooling head 10 of this application includes a first body 11, a water inlet pipe 12, and a water outlet pipe 13. The first body 11 internally forms a first cold inlet 111, a first cold outlet 112, a first hot inlet 113, and a first hot outlet 114. One end of the water inlet pipe 12 is supplied with coolant 2, and the other end is connected to the first cold inlet 111, thereby guiding the coolant 2 into the liquid-cooling module 1 to cool the heating element. Furthermore, one end of the water outlet pipe 13 is supplied with coolant 3 to be cooled, and the other end is connected to the first hot outlet 114, so that the coolant 3 is discharged to the outside for cooling. In actual use, the water inlet pipe 12 and the water outlet pipe 13 can be flexible or rigid pipes; their materials and connection methods (e.g., threads, quick-connect fittings, or welding) are common techniques in the art and will not be described in detail here.

[0027] Specifically, the first water-cooling head 10 further includes a first heat-conducting plate 14, a first water pump 15, a first water collecting plate 16, and a first water-cooling fin assembly 17. The first heat-conducting plate 14 is disposed on one side of the first body 11 for attaching a heating element (not shown), such as a central processing unit or a graphics processing unit. The first heat-conducting plate 14 may be made of a high thermal conductivity metal material (such as copper or aluminum) and may be combined with a thermal interface material (TIM) to improve contact heat transfer efficiency, so as to quickly transfer the heat of the heating element into the first body 11.

[0028] Furthermore, the first body 11 forms a first pump chamber 115 and a first cavity 116, which are separated from each other. The first pump 15 is disposed in the first pump chamber 115 and communicates with the first cavity 116 to drive the flow of coolant 2. In addition, the first water collecting plate 16 and the first water-cooling fin assembly 17 are disposed in the first cavity 116. The first water-cooling fin assembly 17 can increase the fluid contact area to improve heat exchange efficiency. In the art, the first water-cooling fin assembly 17 can be configured as straight fins, wavy fins, or microchannel structures, etc.

[0029] In this embodiment, the first water cooling head 10 includes a first cover plate 18 and a first sealing ring 19. The first cover plate 18 covers the first water pump chamber 115. The first sealing ring 19 is clamped between the first cover plate 18 and the first body 11 to ensure the sealing of the first water pump chamber 115.

[0030] The first body 11 is provided with a first cold water channel 117 and a first hot water channel 118 surrounding the first pump chamber 115. The first cold water channel 117 connects the first cold inlet 111 and the first cold outlet 112. The first hot water channel 118 connects the first hot inlet 113 and the first hot outlet 114. Furthermore, the first body 11 is provided with a first connecting groove 110 connecting the first pump chamber 115 and the first chamber 116. The first water collecting plate 16 is provided with a first opening 160 and a first water collecting trough 161 connecting the first opening 160 at the position corresponding to the first connecting groove 110. The first water collecting trough 161 extends from one side of the first water collecting plate 16 to the opposite side. Additionally, the first chamber 116 is provided with a first cold outlet 1161 and a first hot outlet 1162. The first cold outlet 1161 connects to the first cold water channel 117. The first hot water inlet 1162 connects the first hot water channel 118 and the first water pump chamber 115. In addition, the first body 11 is provided with a first annular groove 1163 around the periphery of the first chamber 116.

[0031] Furthermore, the second water-cooling head 20 includes a second body 21 and a second water pump 22. The second body 21 is provided with a second cold inlet 211, a second hot outlet 212, a second cold port 213, and a second hot port 214. The second water pump 22 is disposed in the second body 21, and the second body 21 is located on one side of the first body 11. The second cold port 213 is connected to the second cold inlet 211, and the second hot port 214 is connected to the second hot outlet 212.

[0032] The water storage tank assembly 30 is disposed between the first water-cooling head 10 and the second water-cooling head 20. The water storage tank assembly 30 includes a water storage tank 31 and a water storage pipe 32. The water storage tank 31 is provided with a water storage inlet 311 and a water storage outlet 312. One end of the water storage pipe 32 is connected to the water storage outlet 312, and the other end is connected to the second cold inlet 211. In this embodiment, a plurality of support columns 313 are spaced apart inside the water storage tank 31. These support columns 313 each have a smooth outer surface to reduce fluid resistance and also serve a structural support function.

[0033] The connecting pipes 40 include a first cold water pipe 41 and a first hot water pipe 42. One end of the first cold water pipe 41 is connected to the first cold outlet 112 and the other end is connected to the water storage inlet 311. One end of the first hot water pipe 42 is connected to the second hot outlet 212 and the other end is connected to the first hot inlet 113.

[0034] Therefore, after the coolant 2 flows into the first body 11 from the inlet pipe 12, a portion of the coolant 2 flows through the first cold water pipe 41 and the first cold water channel 117 before flowing into the water storage tank 31, while the other portion of the coolant 2 flows into the first chamber 116 through the first cold inlet 1161, thereby dissipating heat from the heat-generating element attached to the first heat-conducting plate 14. Additionally, after flowing into the water storage tank 31 from the first cold water pipe 41, the coolant 2 flows out from the water storage pipe 32 and subsequently flows into the second body 21 from the second cold inlet 213, thereby dissipating heat from another heat-generating element. A more detailed description of how the coolant 2 dissipates heat from the heat-generating element follows.

[0035] Please continue reading. Figures 6 to 9 The figures show cross-sectional views of the first water-cooling head, the water inlet pipe, the first annular groove, and the liquid-cooling module at the water-cooling fin assembly. The first water pump 15 is mounted on the first body 11. The first cold inlet 111 and the first cold outlet 112 are located on opposite sides of the first body 11. The first cold water channel 117 connects the first cold inlet 111 and the first cold outlet 112. The water inlet pipe 12 passes through the first cold inlet 111, and the first cold water pipe 41 passes through the first cold outlet 112. The water inlet pipe 12 and the first cold water pipe 41 are located on opposite sides of the first body 11. Furthermore, after the coolant 2 flows into the first chamber 116 from the first cold inlet 1161, the coolant 2 flows along the first annular groove 1163 and into the first water-cooling fin assembly 17.

[0036] like Figure 10 and Figure 11 The image shown is a cross-sectional view of the first water pump location from both sides. The coolant 2 flows into the first chamber 116 and is guided by the first water collection plate 16 and conducted by the first water-cooling fin assembly 17, thereby dissipating heat from the heat-generating element attached to the first heat-conducting plate 14. Additionally, the coolant 2 flowing through the first water-cooling fin assembly 17 exchanges heat with it, carrying away its heat and forming the coolant to be cooled 3. Furthermore, under the operation of the first water pump 15, the coolant to be cooled 3 flows into the first water pump 15 from the first annular groove 1163, the first water collection trough 161 of the first water collection plate 16, and the first opening 160, and finally flows out from the first heat outlet 1162 (see reference). Figure 8 and Figure 5Finally, the coolant 3 will be discharged from the outlet pipe 13.

[0037] In addition, such as Figure 6 and Figure 10 As shown, the first hot inlet 113 and the first hot outlet 114 are located on opposite sides of the first body 11, and the first hot water passage 118 connects the first hot inlet 113 and the first hot outlet 114. The first hot water pipe 42 passes through the first hot inlet 113. The water outlet pipe 13 passes through the first hot outlet 114. The first hot water pipe 42 and the water outlet pipe 13 are located on opposite sides of the first body 11.

[0038] Please refer to Figure 12 This is a cross-sectional view of the second water-cooling head of this application. In addition to the second body 21 and the second water pump 22, the second water-cooling head 20 of this application also includes a second heat-conducting plate 23, a second water-collecting plate 24, and a second water-cooling fin assembly 25. The aforementioned coolant 2 flows into the water storage tank 31, then flows into the second body 21 through the water storage pipe 32, and then into the second body 21 through the second cold inlet 213, thereby dissipating heat from another heat-generating element.

[0039] Specifically, after the coolant 2 flows into the second body 21, it is guided by the second water collection plate 24 and conducted by the second water-cooling fin assembly 25, thereby dissipating heat from the heat-generating elements attached to the second heat-conducting plate 23. Then, the coolant 2 flowing through the second water-cooling fin assembly 25 exchanges heat with the second water-cooling fin assembly 25 and carries away the heat from the second water-cooling fin assembly 25, thus forming the coolant to be cooled 3. In addition, under the operation of the second water pump 22, the coolant to be cooled 3 flows into the second water pump 22 from the second opening 260 of the second water collection plate 24, and finally flows out from the second heat outlet 214 (see...). Figure 8 and Figure 5 The coolant 3 is then sent into the first hot water pipe 42.

[0040] Please refer to Figure 13 This is a cross-sectional view of the present application at the location of the water outlet pipe. After the coolant 3 flows back to the first body 11 from the first hot water pipe 42, a portion of the coolant 3 flows through the first hot water channel 118 and flows out of the first body 11 from the water outlet pipe 13, while the other portion of the coolant 3 flows into the first water pump 15 and flows out of the first body 11 from the water outlet pipe 13 under the action of the first water pump 15.

[0041] In summary, the coolant 2 of this application flows into the first body 11 from the inlet pipe 12, and flows out of the first body 11 and into the water storage tank 31 through the first cold water pipe 41. Then, it flows out of the water storage tank 31 and into the second body 21 through the water storage pipe 32. Subsequently, it flows out of the second body 21 and back into the first body 11 through the first hot water pipe 42, and finally flows out of the first body 11 through the outlet pipe 13.

[0042] According to another aspect of this application, please refer to... Figure 14 This is a three-dimensional schematic diagram of the liquid cooling system of this application. This application also provides a liquid cooling system 100. The liquid cooling system 100 includes a manifold assembly 50, a water-cooling radiator 60, and multiple liquid cooling modules 1. The manifold assembly 50 includes a manifold plate 51, multiple manifolds 52 disposed on the manifold plate 51, a main water inlet pipe 53, and a main water outlet pipe 54. The multiple liquid cooling modules 1 are arranged in parallel on one side of the manifold plate 51, and the water outlet pipe 13 and water inlet pipe 12 of each liquid cooling module 1 are respectively connected to the corresponding manifold 52. Furthermore, the water-cooling radiator 60 is disposed on one side of the manifold assembly 50 and connected to the main water inlet pipe 53 and the main water outlet pipe 54. Thus, the coolant flowing from the water outlet pipes 13 of the liquid cooling modules 1 will flow through the manifolds 52 and into the main water outlet pipe 54. The coolant enters the water radiator 60 from the main outlet pipe 54 and exchanges heat with the water radiator 60 to remove the heat from the coolant, thereby reducing the temperature of the coolant. Then, it flows back to the inlet pipe 12 of each liquid cooling module 1 through the main inlet pipe 53 to complete the coolant circulation operation.

[0043] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
