Technical Field

[0001] This utility model relates to the field of server technology, specifically to a server heat dissipation device. Background Technology

[0002] The rapid development of internet, cloud computing, big data, and artificial intelligence (AI) technologies has led to a significant increase in demand for data centers and large-scale AI computing servers. As core infrastructure for storing and processing massive amounts of data, data centers require the deployment of numerous servers, storage devices, and network equipment. Existing liquid-cooled servers all have separate liquid supply systems. If multiple liquid-cooled servers are set up, the heat generated still needs to be cooled by conventional cabinets to achieve heat exchange and dissipation. For the needs of setting up a large number of servers, it is impossible to effectively dissipate the accumulated heat, which can easily lead to a decrease in server or host performance and thus affect the overall lifespan. Therefore, it is urgent to develop a technical solution to solve the above-mentioned technical problems. Utility Model Content

During operation, the pump draws the heat transfer fluid from the storage tank and passes it through the fluid exchange assembly and the server, where it absorbs the heat generated by the server. Then, the heated heat transfer fluid enters the cooling assembly, which dissipates the heat. Finally, the heat transfer fluid flows back into the storage tank, thus circulating and dissipating heat. The pump body is connected to the storage tank, and the pump body is connected to the drain and exchange assembly via an outlet pipe. The drain and exchange assembly is connected to the cooling assembly via a hot liquid pipe group, and the cooling assembly is connected to the storage tank via a cold liquid pipe.

During operation, the heat-conducting liquid carrying heat enters the heat exchanger, and the cooling fan cools the heat exchanger to reduce the temperature of the heat-conducting liquid. After heat dissipation, the heat-conducting liquid collects in the heat dissipation return pipe and flows back to the storage tank.

[0006] Furthermore, the crossbeam is an L-shaped plate, with one side connected to the mounting frame and the other side used to mount the server.

[0007] Furthermore, the cooling liquid branch pipe includes a main branch pipe valve port and multiple branch pipe branch ports; During operation, the heat transfer fluid flows from the outlet pipe into the cold liquid branch pipe through the main valve port of the branch pipe, and then flows into the server through the branch pipe branch port.

[0008] Furthermore, the hydrothermal branch pipe includes a hydrothermal manifold and a hydrothermal main valve port; During operation, the heat-conducting fluid from the server flows into the heat-conducting branch pipe through the heat-conducting manifold, and the heat-conducting branch pipe uses the heat-conducting main valve to collect the heat-conducting fluid into the heat-conducting pipe assembly.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] refer to Figure 1 - Figure 7 As shown, this utility model provides a server heat dissipation device, including a rack 1, the rack 1 including a cabinet compartment 11 and a heat dissipation compartment 12; the cabinet compartment 11 is provided with a pump body 4, a liquid storage tank 3 and a plurality of liquid draining and replacement components 5, and the heat dissipation compartment 12 is provided with a plurality of cooling components 2; the liquid draining and replacement components 5 are equipped with a server and are connected to the server. During operation, the pump body 4 draws the heat transfer fluid from the storage tank 3 and passes it through the fluid exchange assembly 5 and the server. The heat transfer fluid absorbs the heat generated by the server. Then, the heat-laden heat transfer fluid enters the cooling assembly 2. After the cooling assembly 2 dissipates the heat transfer fluid, the heat transfer fluid finally flows back into the storage tank 3, thus performing a circulating heat dissipation process.

[0014] In this embodiment, the pump body 4 is connected to the liquid storage tank 3, the pump body 4 is connected to the liquid draining and replacement assembly 5 via the liquid outlet pipe 61, the liquid draining and replacement assembly 5 is connected to the cooling assembly 2 via the hot liquid pipe group 62, and the cooling assembly 2 is connected to the liquid storage tank 3 via the cold liquid pipe 63.

[0015] Specifically, the preferred fluid exchange assembly 5 is set in six groups. The storage tank 3 uses the outlet pipe 61 and multiple fluid exchange assemblies 5 to divert the heat transfer fluid, and the heat transfer fluid 62 after heat exchange is collected through the hot liquid pipe group 62, which reduces the pipe group pipeline stroke, reduces hydraulic loss, and improves heat dissipation efficiency.

[0016] In this embodiment, the fluid exchange assembly 5 includes a mounting frame 51, a crossbeam 52, a cold liquid branch pipe 54, and a hot liquid branch pipe 53; a set of mounting frames 51 and multiple crossbeams 52 are assembled to form a side frame structure, and the server 7 is installed between the side frame structures; the cold liquid branch pipe 54 is connected to the server 7 to introduce the heat transfer fluid in the outlet pipe 61 into the server 7, and the server 7 is connected to the hot liquid branch pipe 53 to introduce the heat transfer fluid after heat exchange into the hot liquid pipe assembly 62.

[0017] Specifically, the mounting frame 51 and the horizontal frame 52 form a side frame structure. Preferably, there are a total of 12 side frames, which are combined in pairs to form a total of six groups for installing the server 7. The mounting frame 51 can be equipped with multiple layers of horizontal frames 52 to realize the vertical stacking installation of the server 7 in the vertical space and make full use of the space. The server 7 is a liquid-cooled server, which is connected to the liquid storage pipe 61 and the heat pipe group 62 so that the heat transfer liquid can perform unified liquid cooling circulation for multiple groups of servers 7, avoiding the accumulation of heat dissipation hot air from multiple servers caused by independent liquid cooling circulation of liquid-cooled servers.

[0018] This server cooling system divides the rack 1 into a cabinet compartment 11 and a heat dissipation chamber 12. The heat from the drain and exchange components 5 in the cabinet compartment 11 is carried to the heat dissipation chamber 12 by the liquid cooling circulation driven by the pump 4. The overall integrated layout reduces the space occupied by the equipment, effectively reduces site costs, and avoids heat accumulation caused by a single air-cooled layout. The internal drain and exchange components 5 can be combined and spliced ​​as needed to realize the unified installation and heat exchange of multiple cluster servers 7, improve the heat dissipation efficiency, and further reduce the overall installation and debugging difficulty of the equipment.

[0019] In this embodiment, the features of pipe assemblies, pipe valves, and pipe ports used later can be installed with pipe valve accessories, valve assemblies, and specific pressure regulating settings as needed. These are not part of the technical solutions of this application and embodiment, and therefore will not be described in detail.

[0020] In this embodiment, the cooling assembly 2 includes a heat exchanger 22 and a cooling fan 21 for dissipating heat from the heat exchanger 22; the inlet of the heat exchanger 22 is connected to the hot liquid delivery pipe 621, and the outlet of the heat exchanger 22 is connected to the heat dissipation return pipe 623; during operation, the heat-conducting liquid carrying heat enters the heat exchanger 22, and the cooling fan 21 cools the heat exchange to reduce the temperature of the heat-conducting liquid. After heat dissipation, the heat-conducting liquid collects in the heat dissipation return pipe 623 and flows back to the storage tank 3.

[0021] Specifically, the heat exchanger 22 is a plate-fin type radiator. After the heat-conducting liquid carrying heat enters the heat exchanger 22, the radiator 22 is cooled by the cooling fan 21. After cooling, the heat-conducting liquid flows from multiple heat exchangers 22 into the cooling manifold 623, thus completing the heat dissipation cycle.

[0022] like Figure 7As shown, preferably, the fluid exchange assembly 5 and the cooling assembly 2 can also be configured as a dual-unit system, which further reduces the overall volume and floor space, making it applicable to a wider range of scenarios.

[0023] In this embodiment, the crossbeam 52 is an L-shaped plate. One side of the crossbeam 52 is connected to the mounting frame 51, and the other side of the crossbeam 52 is used to mount the server 7. Specifically, the L-shaped plate facilitates the horizontal installation of the server 7, effectively utilizing vertical space while preventing heat buildup due to prolonged contact between the bottom and the server 7, thus further improving the heat dissipation efficiency of the server 7.

[0024] In this embodiment, the cold liquid branch pipe 54 includes a main branch pipe valve port 541 and multiple branch pipe branch ports 542. During operation, the heat transfer fluid flows from the outlet pipe 61 into the cold liquid branch pipe 54 through the main branch pipe valve port 541, and then flows into the server 7 through the branch pipe branch ports 542.

[0025] Specifically, a single coolant branch pipe 54 can supply liquid to multiple groups of servers 7 through multiple branch pipe outlets 542, thereby achieving rapid distribution of the heat transfer fluid and improving the overall heat dissipation and heat conduction efficiency.

[0026] In this embodiment, the hydrothermal branch pipe 53 includes a hydrothermal manifold 532 and a hydrothermal main valve 531. During operation, the heat-conducting fluid of the server 7 flows into the hydrothermal branch pipe 53 through the hydrothermal manifold 532, and the hydrothermal branch pipe 53 uses the hydrothermal main valve 531 to collect the heat-conducting fluid into the hydrothermal pipe group 62.

[0027] Specifically, the hydrothermal branch pipe 53 is connected to the server 7 through multiple hydrothermal manifolds 532, which collect and concentrate the heat-conducting liquid, and then the heat-conducting liquid is fed into the hydrothermal pipe group 62 through the main hydrothermal valve 531, thereby improving the heat exchange efficiency.

[0028] In this embodiment, the hydrothermal pipe assembly 62 includes a hydrothermal delivery pipe 621 and a heat dissipation return pipe 623. The hydrothermal delivery pipe 621 connects the fluid exchange assembly 5 and the cooling assembly 2 so as to introduce the heat-conducting fluid with heat into the cooling assembly 2. The cooling assembly 2 is connected to the heat dissipation return pipe 623. After heat dissipation, the heat-conducting fluid is collected by the heat dissipation return pipe 623 into the cold liquid pipe 63 and sent into the storage tank 3 to complete the circulation.

[0029] Specifically, the cooling components 2 are preferably configured in multiple groups. The heat transfer pipe 621 can be used to uniformly deliver the heat transfer fluid to the cooling components 2, thereby reducing heat pressure and improving heat dissipation efficiency. The heat transfer fluid after heat dissipation of multiple cooling components 2 is collected into the heat dissipation return pipe 623 for ongoing heat transfer fluid recovery, so that the heat transfer fluid can be sent back to the storage tank 3.

[0030] In this embodiment, the hydrothermal transport pipe 621 is also provided with a replacement section 622; during operation, the replacement section 622 is removed and the external pipeline is connected to the hydrothermal transport pipe 621 to realize the recycling of the heat-conducting fluid with heat.

[0031] Specifically, the replacement section 622 is a detachable pipeline. After disassembly, the hot liquid delivery pipe 621 is connected to the external pipeline to export the heat transfer fluid with heat for recycling or recovery. It can be used in scenarios including but not limited to underfloor heating, industrial heating, and agricultural greenhouses.
