[0054] In order for those skilled in the art to better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.
[0055] The embodiments of the present application provide a server, which is described in detail in combination with the structure and working principle of the server (the technical terms involved must be explained).
[0056] As Figures 1 to 8As shown, the server includes a mainboard module 10, a liquid cooling baseplate 20, a first heat dissipation pipeline 30, and a second heat dissipation pipeline 40. The mainboard body 11 of the mainboard module 10 is provided with a plurality of different heat generating modules, and the plurality of heat generating modules are arranged at intervals along the first direction. The liquid cooling baseplate 20 is arranged on the mainboard body 11, and the outer peripheral contour line of the liquid cooling baseplate 20 is located outside the outer peripheral contour line of the mainboard body 11. The first heat dissipation pipeline 30 is embedded on the surface of the liquid cooling baseplate 20 away from the mainboard body 11 and is in communication with the first sub-liquid cooling plate 51 of the heat generating module with the largest heat generation among the plurality of heat generating modules. The second heat dissipation pipeline 40 is embedded on the surface of the liquid cooling baseplate 20 away from the mainboard body 11 and extends in a curved shape along the first direction. The part of the surface of the liquid cooling baseplate 20 towards the mainboard body 11 is arranged in close contact with at least part of the heat generating modules other than the heat generating module with the largest heat generation, so as to remove heat through the second heat dissipation pipeline 40.
[0057] The liquid cooling baseplate 20 provided by the application can comprehensively cover the heat generating modules on the mainboard body 11, and effectively distribute the cooling liquid through the first heat dissipation pipeline 30 and the second heat dissipation pipeline 40, so as to ensure that the heat is uniformly and effectively removed. By using the heat exchange characteristics of the cooling liquid, the first heat dissipation pipeline 30 preferentially cools the high-power consumption area, while the second heat dissipation pipeline 40 is responsible for other areas, forming a complementary heat dissipation network, which significantly improves the heat dissipation efficiency of the server, ensures that each heat generating module can work normally in a reasonable temperature environment, greatly reduces the operating temperature of the server, and prolongs the service life of the server.
[0058] Further, the second heat dissipation pipeline 40 extends in a curved shape from the front window to the rear window of the server. The design of the curved pipeline takes into account the space layout inside the server, avoids interference with other hardware, and also increases the liquid flow path, which is conducive to the uniform distribution of heat. The second heat dissipation pipeline 40 changes the flow direction of the cooling liquid, which helps to eliminate local hot spots and improve the thermal stability of the server. The technical solution in the embodiment not only optimizes the thermal management inside the server, but also improves the overall reliability and performance of the system.
[0059] It should be noted that in other embodiments, the shape and material of the curved pipeline can be optimized to further improve the heat exchange efficiency and solve the heat dissipation challenge in the complex environment inside the server.
[0060] It should be noted that in other embodiments, the layout and diameter of the first heat dissipation pipeline 30 and the second heat dissipation pipeline 40 can be adjusted to optimize the cooling liquid flow and solve the heat dissipation demand under different server architectures.
[0061] It should be noted that in this application, at least some of the heat-generating modules, except those generating the most heat, have thermally conductive structures to adhere to the surface of the liquid-cooled substrate 20 facing the motherboard body 11. This thermally conductive structure enhances the thermal coupling between the heat-generating modules and the liquid-cooled substrate 20, improving heat conduction efficiency. Furthermore, the thermally conductive structure fills the tiny gaps between the heat-generating modules and the liquid-cooled substrate 20, reducing thermal resistance and promoting rapid heat transfer. The technical solution in this embodiment allows even heat-generating modules that are not in direct contact to be effectively cooled, further optimizing the overall heat dissipation performance of the server. In other embodiments, the efficiency of the thermally conductive structure can be improved by using materials with higher thermal conductivity, solving the heat dissipation problem of high-density servers.
[0062] Optionally, the thermally conductive structure includes at least one of a thermal pad and thermal paste.
[0063] It should be noted that in this application, the first heat dissipation pipe 30 and the second heat dissipation pipe 40 are connected in parallel. This ensures that the coolant can flow simultaneously through the high-power area (the heat-generating module with the largest heat output) and the second-highest heat-generating module (the low-power area), balancing the cooling needs of the entire server. Through parallel pipes, even if the heat dissipation demand in one area increases, it does not affect the cooling effect in another area, ensuring the stability and reliability of the system. The technical solution in this embodiment improves the utilization rate of the coolant, reduces energy consumption, and lowers maintenance costs. In other embodiments, the coolant flow rate in the pipes can be dynamically adjusted to address the heat dissipation needs under different load conditions, solving the heat dissipation problem of the server under different operating states.
[0064] like Figure 1 and Figure 2As shown, multiple heat dissipation modules include a processor module 50, which has a first sub-liquid cooling plate 51; the first heat dissipation pipe 30 includes a first sub-liquid inlet pipe 31 and a first sub-liquid outlet pipe 32, wherein the two ends of the first sub-liquid inlet pipe 31 are respectively connected to the liquid inlet connector 100 of the server and the inlet of the first sub-liquid cooling plate 51, and the two ends of the first sub-liquid outlet pipe 32 are respectively connected to the liquid outlet connector 200 of the server and the outlet of the first sub-liquid cooling plate 51; wherein the first sub-liquid inlet pipe 31 and the first sub-liquid outlet pipe 32 both extend in a straight line in a first direction. In this way, the processor module 50 is the heat-generating module with the highest power consumption and the highest heat generation. By setting the first heat dissipation pipe 30 to include a first sub-inlet pipe 31 and a first sub-outlet pipe 32, and making the two ends of the first sub-inlet pipe 31 connected to the server's inlet connector 100 and the inlet of the first sub-liquid cooling plate 51 respectively, and the two ends of the first sub-outlet pipe 32 connected to the server's outlet connector 200 and the outlet of the first sub-liquid cooling plate 51 respectively, it is beneficial to achieve effective heat dissipation of the CPU chip of the processor module 50, thereby ensuring that the CPU chip can operate normally under suitable ambient temperature.
[0065] It should be noted that in this application, the processor module 50 mentioned above can be a central processing unit module (i.e., a CPU module), an XPU module, or of course, a GPU module.
[0066] like Figure 3 As shown, a first clearance via 24 is provided at the position opposite to the processor module 50 on the liquid cooling substrate 20. Part of the periphery of the first clearance via 24 is used to support the processor module 50. The first clearance via 24 can cool the CPU chip of the processor module 50 by direct contact with the air.
[0067] like Figure 5As shown, the first sub-liquid cooling plate 51 has a first sub-flow channel 511 and a second sub-flow channel 512. The first sub-flow channel 511 and the second sub-flow channel 512 are connected in series, with the end of the first sub-flow channel 511 away from the second sub-flow channel 512 forming the inlet of the first sub-liquid cooling plate 51, and the end of the second sub-flow channel 512 away from the first sub-flow channel 511 forming the outlet of the first sub-liquid cooling plate 51. Multiple first fin structures 5111 are spaced apart within the first sub-flow channel 511, and multiple second fin structures 5121 are spaced apart within the second sub-flow channel 512. This series-connected first sub-flow channel 511 and second sub-flow channel 512, with each sub-flow channel 511 and second sub-flow channel 512 respectively equipped with multiple first fin structures 5111 and multiple second fin structures 5121, optimizes the flow path of the coolant, increases the heat exchange area, and thus improves heat dissipation efficiency. The introduction of multiple first fin structures 5111 and multiple second fin structures 5121 increases the contact area between the fluid and the solid, accelerating heat diffusion; significantly improving the heat dissipation effect of the processor module 50, reducing the operating temperature, and extending its service life.
[0068] It should be noted that in other embodiments, the shape and density of the fin structure can be adjusted to adapt to the heat dissipation requirements of different heat-generating modules, thus solving the heat dissipation problem of diverse heat-generating modules inside the server.
[0069] It should be noted that in this application, the first spacing between any two adjacent first fin structures 5111 in the plurality of first fin structures 5111 is equal; the second spacing between any two adjacent second fin structures 5121 in the plurality of second fin structures 5121 is equal; wherein, the first spacing and the second spacing are different.
[0070] Preferably, the first spacing is greater than the second spacing. This differentiated channel design takes into account the heat distribution in different heat-generating areas. By adjusting the first spacing between two adjacent first fin structures 5111 within the first sub-channel 511, and adjusting the second spacing between two adjacent second fin structures 5121 within the second sub-channel 512, more precise heat management is achieved. The larger first spacing is suitable for areas with concentrated heat, while the smaller second spacing is suitable for areas with dispersed heat. This design helps improve the heat exchange efficiency of the coolant. The technical solution in this embodiment enables the server's cooling system to better adapt to various heat generation modes, improving the overall heat dissipation capacity of the system.
[0071] It should be noted that in other embodiments, the problem of insufficient adaptability of the heat dissipation system can also be solved by dynamically adjusting the channel spacing to respond to changes in the server's operating status.
[0072] It should be noted that, in this application, considering that the power consumption of the hard drive chip in the first hard drive module 60 is second only to the CPU chip, in order to ensure the heat dissipation reliability of the hard drive chip, such as Figure 4 As shown, the multiple heat-generating modules include a first hard disk module 60, which has a second sub-liquid cooling plate 61; the second heat dissipation pipe 40 includes a second sub-liquid inlet pipe 41 and a second sub-liquid outlet pipe 42, wherein the two ends of the second sub-liquid inlet pipe 41 are respectively connected to the inlet of the inlet connector 100 and the inlet of the second sub-liquid cooling plate 61, and the two ends of the second sub-liquid outlet pipe 42 are respectively connected to the outlet of the drain connector 200 and the outlet of the second sub-liquid cooling plate 61; wherein, in a second direction perpendicular to the first direction, the second sub-liquid inlet pipe 41 and the second sub-liquid outlet pipe 42 are located on both sides of the first sub-liquid inlet pipe 31 and the first sub-liquid outlet pipe 32, and both the second sub-liquid inlet pipe 41 and the second sub-liquid outlet pipe 42 extend in a curved shape. In this way, the second sub-liquid cooling plate 61 effectively removes heat generated by the hard disk chip, thereby ensuring the reliable operation of the hard disk chip. Furthermore, by positioning the second sub-inlet pipe 41 and the second sub-outlet pipe 42 on opposite sides of the first sub-inlet pipe 31 and the first sub-outlet pipe 32, respectively, and by having both sub-inlet pipes 41 and 42 extend in a curved manner, the internal space of the server is fully utilized, cross-interference between pipes is avoided, and the system structure is simplified. Separating the second sub-inlet pipe 41 and the second sub-outlet pipe 42 reduces pressure loss during coolant flow and improves coolant circulation efficiency. The technical solution in this embodiment makes the server's cooling system more compact, reducing manufacturing costs and installation difficulty.
[0073] It should be noted that in other embodiments, the space utilization can be further optimized by introducing a three-dimensional pipeline design, thus solving the problem of heat dissipation layout with limited internal space of the server.
[0074] It should be noted that in this application, the second sub-liquid cooling plate 61 has a third sub-flow channel, which is U-shaped, and the openings at both ends of the U-shape form the inlet and outlet of the second sub-liquid cooling plate 61, respectively.
[0075] like Figure 2 and Figure 3 As shown, the second clearance through-hole 25 is used to avoid the second sub-liquid cooling plate 61. Specifically, as... Figure 3 As shown, a second clearance through hole 25 is provided at the position opposite to the first hard disk module 60 on the liquid-cooled substrate 20. Part of the periphery of the second clearance through hole 25 is used to support the first hard disk module 60. The second clearance through hole 25 can cool the second sub-liquid cooling plate 61 of the first hard disk module 60 by direct contact with the air.
[0076] It should be noted that, in this application, the first direction mentioned above refers to the direction from the front window to the rear window of the server, and the second direction mentioned above refers to the direction perpendicular to the direction from the front window to the rear window of the server.
[0077] like Figure 2 and Figure 4 As shown, the first hard drive module 60 also includes a hard drive chip and a heat spreader 62. The heat spreader 62 wraps around at least a portion of the outer periphery of the hard drive chip. At least a portion of the sidewall of the heat spreader 62 is attached to a second sub-liquid cooling plate 61, and the surface of the heat spreader 62 facing away from the motherboard body 11 is attached to the surface of the liquid cooling substrate 20 facing the motherboard body 11. In this way, the addition of the heat spreader 62 ensures that the heat generated by the hard drive chip is evenly distributed, avoiding localized overheating. The heat spreader 62, through its excellent thermal conductivity, rapidly diffuses the heat from the hard drive chip onto a larger surface area, improving heat dissipation efficiency. Furthermore, by attaching at least a portion of the sidewall of the heat spreader 62 to the second sub-liquid cooling plate 61, and by attaching the surface of the heat spreader 62 facing away from the motherboard body 11 to the surface of the liquid cooling substrate 20 facing the motherboard body 11, the hard drive temperature is effectively controlled, ensuring reliable heat dissipation for the hard drive chip and guaranteeing the stability and security of data storage.
[0078] It should be noted that, in other embodiments of this application, the heat conduction performance can be further improved by increasing the thickness of the heat spreader 62 or by using composite materials, thereby solving the heat dissipation problem of high-density hard disk arrays.
[0079] like Figure 6 As shown, the motherboard body 11 is also provided with multiple connectors 111, which are spaced apart. Multiple heat dissipation modules include board components 70, which include multiple stacked chip particles 71. Each chip particle 71 corresponds one-to-one with a connector 111, and each chip particle 71 is connected to the motherboard body 11 through its corresponding connector 111. At least the topmost chip particle 71 is directly attached to the liquid cooling substrate 20. This direct contact between the topmost chip particle 71 and the liquid cooling substrate 20 ensures efficient heat dissipation of the board component 70 while also accommodating the layout of the multiple chip particles 71.
[0080] like Figure 6As shown, the plurality of chip particles 71 include at least two layers of chip particles 71 stacked in a staggered manner. The number of connectors 111 is the same as the number of chip particles 71, and the height of each connector 111 is different to accommodate different layers of chip particles 71. The uppermost chip particle 71 is directly attached to the liquid-cooled substrate 20. A first heat-conducting block 72 is disposed between the lower chip particle 71 and the liquid-cooled substrate 20 to transfer heat to the liquid-cooled substrate 20. In this way, the first heat-conducting block 72, with its good thermal conductivity, transfers the heat from the lower chip particle 71 to the liquid-cooled substrate 20, realizing vertical heat conduction. The technical solution in this embodiment effectively controls the temperature of the chip particles 71, avoiding data errors and system instability caused by overheating.
[0081] It should be noted that in this application, the aforementioned board component 70 can be a memory module, and the corresponding chip 71 can be the memory itself.
[0082] It should be noted that in other embodiments, the heat conduction efficiency can be improved and the problem of uneven heat dissipation in multi-layer memory can be solved by optimizing the material and shape of the first heat-conducting block.
[0083] It should be noted that in this application, the spacing between the two layers of chip particles 71 is not less than 0.5 mm; the thickness of the first heat-conducting block 72 ranges from 0 to 1.2 mm. Thus, by setting the thickness range of the first heat-conducting block 72 to be greater than the spacing range between adjacent layers of chip particles 71, the thickness of the first heat-conducting block 72 is ensured to be sufficiently large, thereby ensuring that the lower chip particle in the two staggered stacked layers of chip particles 71 can achieve effective heat dissipation through the corresponding first heat-conducting block 72.
[0084] Furthermore, precisely controlling the spacing between the chip particles 71 and the thickness of the first heat-conducting block 72 helps balance heat conduction and airflow, optimizing heat dissipation. A reasonable spacing and thickness of the first heat-conducting block 72 ensure effective heat transfer while preventing airflow obstruction, creating a good heat dissipation environment. The technical solution in this embodiment ensures the stability and reliability of the board assembly 70 under high load operation, extending the server's lifespan.
[0085] It should be noted that in other embodiments, the dynamic adjustment problem of memory heat dissipation can also be solved by dynamically adjusting the interval distance and the thickness of the first heat-conducting block 72 in response to changes in the internal temperature of the server.
[0086] Preferably, the thickness of the first heat-conducting block 72 is 1 mm.
[0087] like Figures 1 to 4As shown, the multiple heat-generating modules also include a second hard disk module 80. The second hard disk module 80 includes a second hard disk body 81 and a second heat-conducting block 82. The second hard disk body 81 is connected to the motherboard body 11 via a plug-in connection, and the liquid cooling substrate 20 has a clearance notch 21 at a position opposite to the second hard disk body 81. The second heat-conducting block 82 is located at the clearance notch 21 and connected to the liquid cooling substrate 20, with the surface of the second heat-conducting block 82 facing the motherboard body 11 in contact with the second hard disk body 81. Thus, the design of the clearance notch 21 avoids direct contact between the liquid cooling substrate 20 and the second hard disk body 81, ensuring normal plugging and unplugging and maintenance of the second hard disk body 81. The existence of the clearance notch 21 does not affect the overall performance of the liquid cooling system, while providing necessary operating space for the second hard disk body 81. The technical solution in this embodiment simplifies the replacement process of the second hard disk body 81 and improves the maintainability and scalability of the server.
[0088] Furthermore, a second heat-conducting block 82 is provided at the clearance notch 21 and connected to the liquid-cooled substrate 20 to transfer the heat generated by the second hard disk drive body 81. The introduction of the second heat-conducting block 82 compensates for the heat conduction loss caused by the clearance notch 21, ensuring the effective removal of heat from the second hard disk drive body 81; the second heat-conducting block 82, through its excellent thermal conductivity, transfers the heat generated by the second hard disk drive body 81 to the liquid-cooled substrate 20, realizing indirect heat conduction. The technical solution in this embodiment ensures temperature control of the hard disk drive during high-load operation and avoids the risk of data corruption.
[0089] It should be noted that in other embodiments, the heat dissipation efficiency of the hard disk can be improved by enhancing the thermal conductivity of the second heat-conducting block 82, thereby solving the temperature control problem of the high-density hard disk array.
[0090] It should be noted that in other embodiments, the size and position of the clearance notch 21 can be optimized to better accommodate hard drives of different specifications, thus solving the compatibility problem of hard drive replacement in the server.
[0091] It should be noted that in this application, the second hard disk module 80 mentioned above usually refers to an M.2 solid-state drive.
[0092] In one exemplary embodiment, the second heat-conducting block 82 is detachably connected to the liquid-cooled substrate 20. This ensures that after the second heat-conducting block 82 is removed, operational space is provided for the insertion and removal of the second hard disk body 81.
[0093] like Figure 4As shown, the multiple heat dissipation modules also include a network card module 90. The network card module 90 includes a support carrier 91, a network card body, and an optical module 93. The support carrier 91 is connected to the motherboard body 11 via a plug-in connection. The support carrier 91 has a receiving slot and a deformable insertion slot. The opening of the receiving slot faces the liquid-cooled substrate 20, and the opening of the insertion slot faces the front window of the server. The network card body is disposed in the receiving slot, and a third heat-conducting block 92 is attached to the surface of the network card body facing away from the receiving slot. The third heat-conducting block 92 is attached to the liquid-cooled substrate 20. At least a portion of the optical module 93 is inserted into the insertion slot to support the slot wall and to make the heat sink 94 located on the outer surface of the insertion slot attached to the liquid-cooled substrate 20. In this way, a deformable insertion slot is provided, and a third heat-conducting block 92 is provided between the network card body and the liquid-cooled substrate 20. The deformable design of the connector slot ensures flexible installation of the network card module 90, while the third heat-conducting block 92 ensures good thermal contact between the network card body and the liquid-cooled substrate 20. The third heat-conducting block 92 fills the gap between the network card body and the liquid-cooled substrate 20, reducing thermal resistance and improving heat conduction efficiency. The technical solution in this embodiment effectively controls the network card temperature, ensuring the stability and speed of network communication. Of course, in other embodiments, adaptive thermal conductive materials can be introduced to automatically adjust the heat conduction performance and solve the heat dissipation problem of the server's network card module 90 under different operating conditions.
[0094] Furthermore, the optical module 93 inserted into the slot supports the slot wall, allowing the heat sink 94 to adhere to the liquid-cooled substrate 20. This combination of the optical module 93 and the heat sink 94 ensures that the heat generated by the optical module 93 can be rapidly transferred to the liquid-cooled substrate 20, achieving efficient heat exchange. The heat from the optical module 93 is directly conducted to the liquid-cooled substrate 20 through the heat sink 94, reducing the heat conduction path and improving heat dissipation efficiency. The technical solution in this embodiment effectively controls the temperature of the optical module 93, ensuring the stability and reliability of high-speed data transmission. Of course, in other embodiments, the heat conduction performance can be further improved by optimizing the material and structure of the heat sink 94, solving the heat dissipation problem of the server optical module 93 under high load.
[0095] like Figure 4 As shown, there are two optical modules 93 and two plug slots. The two plug slots correspond one-to-one with the two optical modules 93, and each plug slot has a heat sink 94 on its outer surface.
[0096] like Figure 3As shown, the liquid-cooled substrate 20 has a first guide groove 22 and a second guide groove 23 on the surface of the side opposite to the motherboard body 11. The first guide groove 22 and the second guide groove 23 are independently provided. The first guide groove 22 extends in a straight line in the first direction, and the second guide groove 23 is curved and compressed in the first direction. The first heat dissipation pipe 30 is located in the first guide groove 22, and the second heat dissipation pipe 40 is located in the second guide groove 23.
[0097] like Figure 1 and Figure 4 As shown, the server also includes a leakage detection structure 110, which is attached to the surface of the liquid-cooled substrate 20 on the side opposite to the motherboard body 11, and the leakage detection structure 110 at least covers the leakage risk area. In this way, the setting of the leakage detection structure 110 enables real-time and effective detection of the leakage risk area, thereby ensuring that measures are taken immediately to resolve the leakage problem after leakage information is detected.
[0098] It should be noted that, in this application, the aforementioned leakage detection structure 110 can be a leakage detection membrane, or of course, a leakage detection line.
[0099] like Figure 1 and Figure 4 As shown, the leakage risk area includes at least the locations where both ends of the first sub-inlet pipe 31 are connected to the inlet connector 100 and the inlet of the first sub-liquid cooling plate 51, respectively; and / or, the locations where both ends of the first sub-outlet pipe 32 are connected to the outlet of the drain connector 200 and the outlet of the first sub-liquid cooling plate 51, respectively; and / or, the locations where both ends of the second sub-inlet pipe 41 are connected to the inlet of the inlet connector 100 and the inlet of the second sub-liquid cooling plate 61, respectively; and / or, the locations where both ends of the second sub-outlet pipe 42 are connected to the outlet of the drain connector 200 and the outlet of the second sub-liquid cooling plate 61, respectively. This ensures that the leakage risk area in this application can be effectively detected in real time by the leakage detection structure 110.
[0100] It should be noted that, in this application, due to the presence of the liquid-cooled substrate 20, and the fact that the first heat dissipation pipe 30 is located in the first guide groove 22 and the second heat dissipation pipe 40 is located in the second guide groove 23, even if leakage occurs in the leakage risk area, the liquid-cooled substrate 20 itself has a certain barrier effect, preventing the leakage from directly contacting the motherboard body 11.
[0101] like Figure 7 and Figure 8As shown, the inlet of the first sub-inlet pipe 31 is connected to the inlet of the first sub-liquid cooling plate 51 via a detachable first locking structure; the outlet of the first sub-outlet pipe 32 is connected to the outlet of the first sub-liquid cooling plate 51 via a detachable second locking structure, for the purpose of replacing the first sub-liquid cooling plate 51. Thus, the detachable first and second locking structures facilitate the maintenance and upgrading of the first sub-liquid cooling plate 51, allowing replacement without completely disassembling the server. Furthermore, the design of the first and second locking structures considers the sealing and maintainability of the liquid cooling system, ensuring no coolant leakage and facilitating on-site maintenance. The technical solution in this embodiment simplifies the server maintenance process and reduces downtime caused by heat dissipation system failures.
[0102] Furthermore, the second locking structure complements the first locking structure, jointly maintaining the integrity and effectiveness of the liquid cooling system. The technical solution in this embodiment ensures the stability of the server during long-term operation and reduces failures caused by improper maintenance of the heat dissipation system.
[0103] Specifically, in this application, reference is made to Figure 7 and Figure 8 As can be seen, the first and second locking structures in this application are integrally formed, that is, the locking assembly 300 includes the first and second locking structures. Further, the locking assembly 300 includes a locking base 301 and a locking cover plate 302, and the locking base 301 and the locking cover plate 302 are connected by fasteners to ensure convenient installation and disassembly of both. The surface of the locking base 301 facing the locking cover plate 302 has two first arc-shaped grooves for locking... The surface of the cover plate 302 facing the locking base 301 has two second arc-shaped grooves. The two first arc-shaped grooves correspond one-to-one with the two second arc-shaped grooves and form two circular limiting holes. The two circular limiting holes are used to limit the connection between the first sub-inlet pipe 31 of the first heat dissipation pipe 30 and the inlet of the first sub-liquid cooling plate 51, and the connection between the first sub-outlet pipe 32 of the first heat dissipation pipe 30 and the outlet of the first sub-liquid cooling plate 51, so as to ensure the convenience of replacing the first sub-liquid cooling plate 51.
[0104] It should be noted that in other embodiments, the sealing performance of the locking structure can be enhanced to prevent coolant leakage and solve the security issues of the server operating environment.
[0105] It should be noted that in other embodiments, the maintenance time can be further reduced and the problem of server maintenance efficiency can be solved by introducing fast connection technology.
[0106] The heat dissipation process of the server in this application is as follows: When the server starts up, coolant enters the first heat dissipation pipe 30 and the second heat dissipation pipe 40 from the inlet connector 100. The coolant first flows through the first sub-inlet pipe 31 and enters the first sub-channel 511 of the first sub-liquid cooling plate 51, where it exchanges heat with the CPU chip of the processor module 50 through the first fin structure 5111. Then, it flows through the second sub-channel 512 and further absorbs heat through the second fin structure 5121. Finally, it returns to the drain connector 200 through the first sub-drain pipe 32. At the same time, the coolant also flows through the second sub-inlet pipe 41 and enters the second sub-liquid cooling plate 61, where it exchanges heat with the hard disk chip of the first hard disk module 60. Then, it returns to the drain connector 200 through the second sub-drain pipe 42. During this process, the coolant also exchanges heat with the board assembly 70 and the network card module 90 through the liquid cooling substrate 20, ensuring that the temperature of each heat-generating module inside the server is effectively controlled, thereby ensuring the stable operation and data processing capabilities of the server.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
