Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and in particular, to a heat dissipation device and a server. Background Art

[0002] In the related art, it is pointed out that with the continuous progress of AI technology, the computing power and power consumption of a single GPU card continue to increase, making it particularly important to effectively dissipate heat from the GPU card in its server. In the design of an AI all-in-one cabinet, considering the development and changes of computing nodes (mainly GPU cards), the design of the all-in-one cabinet must also be adjusted accordingly to meet new requirements. The current practice is to integrate the power supply unit, the GPU server, and the cooling distribution unit (CDU) in the same cabinet, and usually use the cold plate liquid cooling method for heat dissipation.

[0003] Specifically, two liquid cooling pipelines are configured at the rear of the cabinet to provide channels for the incoming and outgoing coolant respectively. All server computing nodes are connected to the CDU located at the bottom of the cabinet through these two pipelines, and the CDU is responsible for providing secondary-side heat dissipation processing for the server. However, with the replacement of each generation of computing nodes, this design often requires re-designing and adapting to a new cabinet, resulting in increased costs and wasted resources. Because the development speed of computing nodes is significantly faster than the evolution speed of the cabinet, in most cases, the modification of the cabinet is only a passive adjustment made to meet the needs of new computing nodes. This situation not only increases the cost of designing a new cabinet but also consumes a large amount of human resources. Summary of the Invention

[0046] As pointed out in the related art, with the continuous progress of AI technology, the computing power and power consumption of a single GPU card continue to increase, making it particularly important to effectively dissipate heat from the GPU cards in its servers. Currently, AI servers mainly use two cooling methods, air cooling and cold plate liquid cooling, to address this challenge. Since different models of GPU cards have different heat dissipation requirements, the design of the internal cooling system of its servers will also vary.

[0047] In the design of the AI full cabinet, considering the development and changes of computing nodes (mainly GPU cards), the design of the full cabinet must also be adjusted accordingly to meet new requirements. The current approach is to integrate the power supply unit, GPU servers, and the cooling distribution unit (CDU) within the same cabinet, and usually use cold plate liquid cooling for heat dissipation. Specifically, two liquid cooling pipelines are configured at the rear of the cabinet to provide channels for the incoming and outgoing coolant. All server computing nodes are connected to the CDU located at the bottom of the cabinet through these two pipelines, and the CDU is responsible for providing secondary side heat dissipation for the servers.

[0048] However, with the update of each generation of computing nodes, this design often requires re-designing and adapting to a new cabinet, resulting in increased costs and wasted resources. Because the development speed of computing nodes is significantly faster than the evolution speed of the cabinet, in most cases, the changes to the cabinet are only passive adjustments made to meet the requirements of new computing nodes. This current situation not only increases the cost of designing a new cabinet but also consumes a large amount of human resources. Therefore, how to reduce the production cost of the cabinet has become an urgent issue to be solved.

[0049] Based on the above considerations, in order to reduce the production cost of the cabinet, the applicant has designed a heat dissipation device through in-depth research. The following refers to Figures 1-7 Describe the heat dissipation device 100 according to the embodiment of the first aspect of the present application.

[0050] As Figures 1-7 shown, Figure 1 is a schematic diagram of a heat dissipation device provided according to an embodiment of the present application; Figure 2 is a partial enlarged schematic diagram of the heat dissipation device of the embodiment of the present application; Figure 3 is a schematic diagram of a computing node in an embodiment of the present application; Figure 4 is a schematic diagram of a computing node in another embodiment of the present application; Figure 5 is a schematic diagram of a computing node in yet another embodiment of the present application; Figure 6 is a schematic diagram of a computing node in still another embodiment of the present application; Figure 7 is a schematic diagram of a computing node in yet another embodiment of the present application.

[0051] The heat dissipation device 100 according to the embodiment of the first aspect of the present application is used to dissipate heat from the computing node 200. The heat dissipation device 100 includes: a cabinet 1, a cold quantity distribution unit 2, a water inlet assembly 3, and a water outlet assembly 4.

[0052] Specifically, the computing node 200 is disposed within the cabinet 1. Each computing node 200 has a water inlet 201 and a water outlet 202. The cooling capacity distribution unit 2 is disposed within the cabinet 1. The water inlet assembly 3 is disposed on the cabinet 1. The water inlet assembly 3 is connected between the cooling capacity distribution unit 2 and each computing node 200. The water inlet assembly 3 includes a plurality of water inlet pipes 31. The plurality of water inlet pipes 31 all extend in the vertical direction and are spaced apart in the first direction. The water inlet 201 of each computing node 200 is communicated with at least one of the plurality of water inlet pipes 31. The water outlet assembly 4 is disposed on the cabinet 1. The water outlet assembly 4 is connected between the cooling capacity distribution unit 2 and each computing node 200. The water outlet assembly 4 includes a plurality of water outlet pipes 41. The plurality of water outlet pipes 41 all extend in the vertical direction and are spaced apart in the first direction. The water outlet 202 of each computing node 200 is communicated with at least one of the plurality of water outlet pipes 41.

[0053] It can be understood that the cabinet 1, as the basic structure of the entire heat dissipation device 100, is used to accommodate the computing node 200, the cooling capacity distribution unit 2 (CDU), the water inlet assembly 3, the water outlet assembly 4, etc. The computing node 200 is installed within the cabinet 1, and each computing node 200 has a water inlet 201 and a water outlet 202. In this way, each computing node 200 can be connected and communicated with the cooling capacity distribution unit 2 through its own water inlet 201 and water outlet 202, thereby reducing the connection difficulty between the computing node 200 and the cooling capacity distribution unit 2.

[0054] The cooling capacity distribution unit 2 is located within the cabinet 1. The cooling capacity distribution unit 2 is used to provide power for the circulation of the refrigerant and regulate the temperature of the computing node 200. In this way, the cooling capacity distribution unit 2 conveys the refrigerant to the computing node 200. The refrigerant exchanges heat with the computing node 200. The refrigerant carrying heat after heat exchange flows back from the computing node 200 to the cooling capacity distribution unit 2, and the refrigerant is heat-exchanged again within the cooling capacity distribution unit 2 to reduce the temperature of the refrigerant.

[0055] The water inlet assembly 3 is located on the cabinet 1. The water inlet assembly 3 is used to distribute the refrigerant to the water inlets 201 of the respective computing nodes 200. The water inlet assembly 3 includes a plurality of water inlet pipes 31. Each water inlet pipe 31 extends in the vertical direction. The water inlet pipes 31 are spaced apart in the first direction (such as Figure 1 the first direction shown). Each water inlet 201 of the computing node 200 is communicated with at least one water inlet pipe 31. In this way, each computing node 200 can be connected to the water inlet assembly 3 and communicated with the cooling capacity distribution unit 2, ensuring that each computing node 200 can receive sufficient and uniform refrigerant supply. Thus, the water inlet assembly 3 can adapt to different numbers and layouts of computing nodes 200, which helps to reduce the cost of re-designing the cabinet 1 due to the replacement of the computing nodes 200.

[0056] The water outlet assembly 4 is located on the cabinet 1. The water outlet assembly 4 is used to collect the refrigerant flowing out from each computing node 200 and transport the refrigerant collected by each computing node 200 back into the cooling capacity distribution unit. The water outlet assembly 4 includes a plurality of water outlet pipes 41, and each water outlet pipe 41 extends in the vertical direction. The water inlet pipes 31 are arranged at intervals in the first direction (such as Figure 1 the first direction shown). The water outlet 202 of each computing node 200 is connected to at least one water outlet pipe 41. In this way, each computing node 200 can be connected to the water outlet assembly 4 and communicate with the cooling capacity distribution unit 2, ensuring that the refrigerant in each computing node 200 flows back to the cooling capacity distribution unit 2. Therefore, the water outlet assembly 4 can adapt to different numbers and layouts of computing nodes 200. The water outlet assembly 4 and the water inlet assembly 3 cooperate with each other, which helps to reduce the cost of updating the design of the cabinet 1 caused by the replacement of the computing nodes 200.

[0057] The working process of the heat dissipation device 100 of the present application will be described below: First, the refrigerant flows out from the cooling capacity distribution unit 2 and flows into the water inlet assembly 3. Then, the refrigerant flows from the water inlet assembly 3 into the computing node 200 through the water inlet 201. The refrigerant exchanges heat in the computing node 200. After heat exchange, the refrigerant carrying heat flows out from the computing node 200 and flows into the water outlet pipe 41 through the water outlet 202. Finally, the refrigerant carrying heat after heat exchange flows out from the water outlet pipe 41 and flows back to the cooling capacity distribution unit 2, thus ensuring the heat dissipation effect of the computing node 200.

[0058] In a specific embodiment, referring to Figure 1 as shown, both the computing node 200 and the cooling capacity distribution unit 2 are located in the cabinet 1. The water inlet assembly 3 and the water outlet assembly 4 are both located on the cabinet 1. The water inlet assembly 3 includes three water inlet pipes 31, and the water outlet assembly 4 includes three water outlet pipes 41. The water inlet pipes 31 and the water outlet pipes 41 both extend in the up and down direction. There are a first position P1, a second position P2, and a third position P3 on the cabinet 1. One water inlet pipe 31 and one water outlet pipe 41 are provided in the first position P1, and the water inlet pipe 31 and the water outlet pipe 41 are arranged adjacent to each other. One water inlet pipe 31 and one water outlet pipe 41 are provided in the second position P2, and the water inlet pipe 31 and the water outlet pipe 41 are arranged adjacent to each other. One water inlet pipe 31 and one water outlet pipe 41 are provided in the third position P3, and the water inlet pipe 31 and the water outlet pipe 41 are arranged adjacent to each other. In this way, even if different computing nodes 200 are replaced, there is no need to replace the heat dissipation device 100. The water inlet assembly 3 and the water outlet assembly 4 are suitable for being connected and communicating with different computing nodes 200, and there is no need to use long pipes for connection, ensuring that the structure of the heat dissipation device 100 is simple, facilitating assembly and maintenance, and reducing the assembly difficulty and maintenance difficulty.

[0059] That is to say, when the water inlet 201 of the computing node 200 is located at the first position P1, the water inlet 201 of the computing node 200 is connected to the water inlet pipe 31 within the first position P1. When the water outlet 202 of the computing node 200 is located at the first position P1, the water outlet 202 of the computing node 200 is connected to the water outlet pipe 41 within the first position P1; When the water inlet 201 of the computing node 200 is located at the first position P1, the water inlet 201 of the computing node 200 is connected to the water inlet pipe 31 within the first position P1.

[0062] In some other embodiments of the present application, according to actual needs, the number of water inlet pipes and the number of water outlet pipes 41 may not be equal, that is, the number of water inlet pipes may be less than the number of water outlet pipes 41, or the number of water inlet pipes may be more than the number of water outlet pipes 41, and the positions of the water inlet pipes and the water outlet pipes 41 can be arranged according to actual needs to be applicable to more improved computing nodes 200.

[0063] In any embodiment of the present application, a truss 5 is provided on the cabinet body 1, and a plurality of adjusting parts are provided on the truss 5. The upper ends of each water inlet pipe 31 and the upper ends of the corresponding water outlet pipes 41 are both connected to the corresponding adjusting parts.

The water inlet pipe 31 and the water outlet pipe 41 adjust their positions through the corresponding adjusting parts, ensuring that all the computing nodes 200 can be connected to the water inlet pipe 31 and the water outlet pipe 41 through the truss 5.

[0064] It can be understood that each water inlet pipe 31 and the corresponding water outlet pipe 41 are connected to the truss 5 through the adjusting parts. In this way, the water inlet pipe 31 and / or the water outlet pipe 41 in each installation position can be adjusted accordingly according to the positions of the water inlet 201 and / or the water outlet 202 on the computing node 200.

A fixing rod 6 is provided between each water inlet pipe 31 and the cabinet body 1 and between each water outlet pipe 41 and the cabinet body 1. The fixing rod 6 is along a second direction perpendicular to the first direction (such as Figure 2extends in the second direction shown and passes through the adjustment hole 51, and the position of the fixing rod 6 in the adjustment hole 51 in the first direction is adjustable.

[0067] It can be understood that when the structures and sizes between different models or configurations of the computing nodes 200 are different, by adjusting the position of the fixing rod 6 in the adjustment hole 51, the positions of each water inlet pipe 31 and each water outlet pipe 41 relative to the cabinet body 1 can be accurately adjusted. When it is necessary to replace or upgrade the computing node 200, the heat dissipation device 100 can be reconfigured by simply adjusting the position of the fixing rod 6, without the need for large-scale modification of the entire heat dissipation device 100 or re-designing the structure of the heat dissipation device 100, reducing the production cost. Moreover, this can achieve an optimized pipeline layout within an effective space, avoid unnecessary space waste, help reduce the intersection and interference between different pipes, ensure the smooth operation of the heat dissipation device 100, and reduce the failure rate of the heat dissipation device 100.

[0068] For example, referring to Figure 1 and Figure 2 as shown, the adjustment hole 51 is formed as a long through hole extending in the first direction.

[0070] Referring to Figure 1 and Figure 2As shown, an adjusting member 7 is provided between the water inlet pipe 31 and the water outlet pipe 41 in the first position P1. One end of the fixing rod 6 in the first position P1 is connected to the adjusting member 7, and the other end of the fixing rod 6 in the first position P1 is connected to the cabinet body 1.

One water inlet pipe 31 and the corresponding water outlet pipe 41 are respectively arranged in the two adjusting grooves 73, and the distance between the two adjusting grooves 73 is adjustable. Thus, by forming two adjusting grooves 73 arranged back to back on the adjusting member 7 and the distance between the two adjusting grooves 73 being adjustable, the adjustment flexibility of the water inlet assembly 3 and / or the water outlet assembly 4 is improved. The water inlet pipe 31 and / or the water outlet pipe 41 are arranged in the adjusting grooves 73, which not only plays a role in fixing the water inlet pipe 31 and / or the water outlet pipe 41, but also facilitates adjusting the distance between the water inlet pipe 31 and / or the water outlet pipe 41, or facilitating adjusting the relative position between the water inlet pipe 31 and / or the water outlet pipe 41 and the cabinet body 1, and is suitable for assembling with computing nodes 200 of different structures and models, thereby reducing the design cost and production cost of the heat dissipation device 100.

[0072] For example, referring to Figure 1 and Figure 2As shown, two adjusting grooves 73 are formed on the adjusting member 7 within the first position P1. The two adjusting grooves 73 are arranged at intervals in the first direction and have openings facing away from each other. The water inlet pipe 31 within the first position P1 is fixed within one adjusting groove 73, and the water outlet pipe 41 within the first position P1 is fixed within the other adjusting groove 73.

One adjusting groove 73 is formed on each adjusting block 72, and a first adjusting portion is formed on each adjusting block 72. A second adjusting portion is formed on the adjusting base 71. The distance between each adjusting block 72 and the adjusting base 71 is adjusted by the cooperation of the first adjusting portion and the second adjusting portion. Thus, by providing the adjusting groove 73 on each adjusting block 72 and fixing the water inlet pipe 31 and / or the water outlet pipe 41 within the adjusting groove 73, through the cooperation between the first adjusting portion and the second adjusting portion, the position of each adjusting block 72 relative to the adjusting base 71 can be precisely adjusted, thereby achieving precise adjustment of the water inlet pipe 31 and the water outlet pipe 41, and reducing the installation difficulty and maintenance difficulty of the heat dissipation device 100.

[0074] For example, referring to Figure 1 and Figure 2As shown, the adjusting member 7 in the first position P1 has an adjusting base 71 and two adjusting blocks 72. The two adjusting blocks 72 are arranged adjacent to each other in the first direction on both sides of the adjusting base 71. Each adjusting block 72 is formed with an adjusting groove 73, and each adjusting block 72 is formed with a first adjusting portion. The adjusting base 71 is formed with a second adjusting portion.

The water inlet pipe 31 and / or the water outlet pipe 41 in the second position P2 adjusts the relative position with respect to the cabinet body 1 through the cooperation of the first adjusting portion and the second adjusting portion. Alternatively, the distance between the water inlet pipe 31 and the water outlet pipe 41 in the second position P2 is adjusted by the cooperation of the first adjusting portion and the second adjusting portion; The adjusting member 7 in the third position P3 has an adjusting base 71 and two adjusting blocks 72.

Alternatively, the distance between the water inlet pipe 31 and the water outlet pipe 41 in the third position P3 is adjusted by the cooperation of the first adjusting portion and the second adjusting portion.

[0075] For example, the first adjusting portion and the second adjusting portion can adopt meshing teeth for meshing connection to facilitate the adjustment of the distance between the adjusting block 72 and the adjusting base 71. The connection manner of the first adjusting portion and the second adjusting portion includes but is not limited to this.

[0076] In any embodiment of the present application, the heat dissipation device 100 further includes: a flow splitting plate 8, which is disposed on the cabinet 1 and is communicated with the cold quantity distribution unit 2. It can be understood that the flow splitting plate 8 is arranged between the water inlet assembly 3 and the cold quantity distribution unit 2 and between the water outlet assembly 4 and the cold quantity distribution unit 2. In this way, even if the position of the water inlet pipe 31 of the water inlet assembly 3 changes and / or the position of the water outlet pipe 41 of the water outlet assembly 4 changes, the flow splitting plate 8 can still be communicated with the cold quantity distribution unit 2. The water inlet assembly 3 and the water outlet assembly 4 are adapted to be connected to different computing nodes 200, and there is no need to use long pipelines for connection, ensuring that the structure of the heat dissipation device 100 is simple, facilitating assembly and maintenance, reducing the assembly difficulty and maintenance difficulty, and enhancing the adaptability and expandability of the heat dissipation device 100.

[0077] Furthermore, setting the flow splitting plate 8 also plays a role in regulating the refrigerant flow rate, ensuring that the refrigerant can be evenly distributed to each computing node 200, reducing the pressure loss of the refrigerant during transmission, and ensuring that the heat dissipation device 100 can operate efficiently at a relatively low pressure. The flow splitting plate 8 becomes a centralized interface point for centrally managing all pipeline connections to and from the cold quantity distribution unit 2, reducing potential leakage points, and improving the sealing performance and safety of the heat dissipation device 100.

[0078] Describe the working principle of the heat dissipation device 100 provided with the flow splitting plate 8: First, the refrigerant flows out from the cold quantity distribution unit 2 and flows into the flow splitting plate 8. The flow splitting plate 8 distributes the refrigerant to each water inlet pipe 31 according to a preset path, and the water inlet pipe 31 then guides the refrigerant to the corresponding computing node 200. Then, the refrigerant that has absorbed heat in the computing node 200 flows into the corresponding water outlet pipe 41 through the water outlet 202, returns to the flow splitting plate 8 through the water outlet pipe 41, and is then collected by the flow splitting plate 8 and guided back to the cold quantity distribution unit 2 for re-cooling to prepare for re-circulation into the computing node 200 for heat exchange.

[0079] In any embodiment of the present application, the water inlet assembly 3 includes: a water inlet distributor 32, which is connected between the cold quantity distribution unit 2 and each water inlet pipe 31. Each water inlet pipe 31 is communicated with the water inlet distributor 32, and the water inlet distributor 32 is communicated with the cold quantity distribution unit 2 and / or the flow splitting plate 8. It can be understood that the water inlet distributor 32 is arranged between the cold quantity distribution unit 2 and the water inlet pipe 31, so that the refrigerant can be evenly distributed from the cold quantity distribution unit 2 to each water inlet pipe 31, ensuring that each computing node 200 can obtain the same or adjusted refrigerant flow rate according to requirements. By centrally managing the distribution of the refrigerant through the water inlet distributor 32, the complex pipeline layout is reduced, making the structure of the water inlet assembly 3 simple and clear, facilitating assembly, daily maintenance, and troubleshooting.

[0080] For example, referring to Figure 1 and Figure 2 As shown, the water inlet diverter 32 is connected between the flow splitting plate 8 and each water inlet pipe 31. The lower ends of the three water inlet pipes 31 are all connected to the water inlet diverter 32, and the water inlet diverter 32 is in communication with the flow splitting plate 8. In this way, the refrigerant flows from the cooling capacity distribution unit 2 into the flow splitting plate 8, then flows from the flow splitting plate 8 into the water inlet diverter 32. Then, the refrigerant flows from the water inlet diverter 32 into each water inlet pipe 31, and finally flows into the computing node 200 through the water inlet 201 of the water inlet pipe 31 for heat exchange.

[0081] In some other embodiments, the water inlet diverter 32 is connected between the cooling capacity distribution unit 2 and each water inlet pipe 31. The lower ends of the three water inlet pipes 31 are all connected to the water inlet diverter 32, and the water inlet diverter 32 is in communication with the cooling capacity distribution unit 2. In this way, the refrigerant flows from the cooling capacity distribution unit 2 into the water inlet diverter 32. Then, the refrigerant flows from the water inlet diverter 32 into each water inlet pipe 31, and finally flows into the computing node 200 through the water inlet 201 of the water inlet pipe 31 for heat exchange. That is, in this embodiment, the flow splitting plate 8 is not provided, and the water inlet diverter 32 is directly connected to the cooling capacity distribution unit 2.

It can be understood that the water inlet diverter 32 is in communication with each water inlet pipe 31 through the first connecting pipe 9. The first connecting pipe 9 connects the water inlet diverter 32 and the water inlet pipe 31, ensuring that the refrigerant can be accurately distributed to each computing node 200. Even if the position of the water inlet pipe 31 is adjusted, it does not affect the connection between the water inlet pipe 31 and the water inlet diverter 32. Even if different computing nodes 200 are replaced, the water inlet assembly 3 can still be connected to the computing node 200, improving the flexibility and convenience of the heat dissipation device 100. The water inlet diverter 32 is connected to the cooling capacity distribution unit 2 and / or the flow splitting plate 8 through the second connecting pipe 10. The second connecting pipe 10 connects the water inlet diverter 32 and the cooling capacity distribution unit 2 and / or the flow splitting plate 8, ensuring that the refrigerant can flow from the cooling capacity distribution unit 2 and / or the flow splitting plate 8 into the second connecting pipe 10, which is convenient for assembly and maintenance.

[0083] For example, referring to Figure 1 and Figure 2As shown in the figure, the first connecting pipe 9 is connected between the water inlet distributor 32 and the water inlet pipe 31. The first connecting pipe 9 is connected to the lower end of the water inlet pipe 31. The second connecting pipe 10 is connected between the water inlet distributor 32 and the flow dividing plate 8. In this way, the refrigerant flows from the cooling capacity distribution unit 2 into the flow dividing plate 8, then flows from the flow dividing plate 8 into the water inlet distributor 32 through the second connecting pipe 10, then the refrigerant flows from the water inlet distributor 32 into the water inlet pipe 31 through the first connecting pipe 9, and finally flows from the water inlet pipe 31 into the computing node 200 through the water inlet 201 for heat exchange.

[0084] In some other embodiments, the first connecting pipe 9 is connected between the water inlet distributor 32 and the water inlet pipe 31. The first connecting pipe 9 is connected to the lower end of the water inlet pipe 31. The second connecting pipe 10 is connected between the water inlet distributor 32 and the cooling capacity distribution unit 2. In this way, the refrigerant flows from the cooling capacity distribution unit 2 into the water inlet distributor 32 through the second connecting pipe 10, then the refrigerant flows from the water inlet distributor 32 into the water inlet pipe 31 through the first connecting pipe 9, and finally flows from the water inlet pipe 31 into the computing node 200 through the water inlet 201 for heat exchange.

[0085] In any embodiment of the present application, the water outlet assembly 4 includes: a water outlet distributor 42, the water outlet distributor 42 is connected between the cooling capacity distribution unit 2 and each water outlet pipe 41, each water outlet pipe 41 communicates with the water outlet distributor 42, and the water outlet distributor 42 communicates with the cooling capacity distribution unit 2 and / or the flow dividing plate 8. It can be understood that a water outlet distributor 42 is arranged between the cooling capacity distribution unit 2 and the water outlet pipe 41, so that the heated refrigerant from each computing node 200 can be centrally recovered, and the refrigerant is guided back to the cooling capacity distribution unit 2 or the flow dividing plate 8 for re-cooling, ensuring that the refrigerant can be evenly and efficiently recovered. By centrally managing the recovery of the refrigerant through the water outlet distributor 42, the complex pipeline layout is reduced, making the structure of the water outlet assembly 4 simple and clear, facilitating assembly, daily maintenance and troubleshooting.

[0086] For example, referring to Figure 1 and Figure 2 As shown in the figure, the water outlet distributor 42 is connected between the flow dividing plate 8 and each water outlet pipe 41. The lower ends of the three water outlet pipes 41 are all connected to the water outlet distributor 42, and the water outlet distributor 42 communicates with the flow dividing plate 8. In this way, after heat exchange, the computing node 200 carrying heat flows into the water outlet pipe 41 through the water outlet 202, then the refrigerant carrying heat flows from the water outlet pipe 41 into the water outlet distributor 42, then flows from the water outlet distributor 42 into the flow dividing plate 8, and finally the refrigerant carrying heat flows from the flow dividing plate 8 into the cooling capacity distribution unit 2 for cooling to prepare for the next cycle.

[0087] In some other embodiments, the water outlet water distributor 42 is connected between the flow splitting plate 8 and each water outlet pipe 41. The lower ends of the three water outlet pipes 41 are all connected to the water outlet water distributor 42, and the water outlet water distributor 42 communicates with the cooling capacity distribution unit 2. In this way, the computing node 200 carrying heat after heat exchange flows into the water outlet pipe 41 through the water outlet 202, and then the refrigerant carrying heat flows from the water outlet pipe 41 into the water outlet water distributor 42.

It can be understood that the water outlet water distributor 42 is communicated with each water outlet pipe 41 through the first connecting pipe 9. The first connecting pipe 9 connects the water outlet water distributor 42 and the water outlet pipe 41, ensuring that the refrigerant can be accurately and efficiently concentrated. Even if the position of the water outlet pipe 41 is adjusted, it does not affect the connection between the water outlet pipe 41 and the water outlet water distributor 42. Even if different computing nodes 200 are replaced, the water outlet assembly 4 can still be connected to the computing node 200, improving the flexibility and convenience of the heat dissipation device 100; the water outlet water distributor 42 is connected to the cooling capacity distribution unit 2 and / or the flow splitting plate 8 through the second connecting pipe 10.

Then, the refrigerant carrying heat flows from the water outlet water distributor 42 into the flow splitting plate 8 through the second connecting pipe 10. Finally, the refrigerant carrying heat flows from the flow splitting plate 8 into the cooling capacity distribution unit 2.

[0090] In some other embodiments, the first connecting pipe 9 is connected between the water outlet water distributor 42 and the water outlet pipe 41. The first connecting pipe 9 is connected to the lower end of the water outlet pipe 41.

Finally, the refrigerant carrying heat flows from the water outlet water distributor 42 into the cooling capacity distribution unit 2 through the second connecting pipe 10.

[0091] In any one of the embodiments of the present application, a third connecting pipe 11 is connected between the water inlet pipe 31 and the water inlet 201 of the computing node 200, and between the water outlet pipe 41 and the water outlet 202 of the computing node 200. It can be understood that the third connecting pipe 11 is used to accurately connect the water inlet pipe 31 and the water inlet 201 of the computing node 200, and the water outlet pipe 41 and the water outlet 202 of the computing node 200, ensuring that the refrigerant can enter and leave each computing node 200 accurately. The third connecting pipe 11 can flexibly adjust the length and angle to meet different installation requirements, improving the flexibility, cooling efficiency and maintenance convenience of the heat dissipation device 100. It not only meets the current heat dissipation requirements, but also provides convenience for the future upgrade of the computing node 200, simplifies the installation and maintenance process of the heat dissipation device 100, and reduces the production cost.

[0092] For example, as shown in Figure 1 and Figure 2 A third connecting pipe 11 is connected between each water inlet pipe 31 and the water inlet 201 of each computing node 200, and a third connecting pipe 11 is connected between each water outlet pipe 41 and the water outlet 202 of each computing node 200. The refrigerant flows from the cooling capacity distribution unit 2 to the flow splitting disc 8, and then from the flow splitting disc 8 into the water inlet water distributor 32 through the second connecting pipe 10. Then the refrigerant flows from the water inlet water distributor 32 into the water inlet pipe 31 through the first connecting pipe 9. Finally, the refrigerant flows from the water inlet pipe 31 into the computing node 200 through the third connecting pipe 11 from the water inlet 201 for heat exchange.
