Description

Technical Field

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

[0002] Related technologies point out that with the continuous advancement of AI technology, the computing power and power consumption of single GPU cards continue to grow, making effective cooling of GPU cards in servers particularly important. In terms of AI cabinet design, considering the development and changes in computing nodes (primarily GPU cards), the entire cabinet design must also be adjusted to meet new requirements. The current practice is to integrate the power supply unit, GPU server, and cooling distribution unit (CDU) into the same cabinet, and typically use cold plate liquid cooling for heat dissipation.

[0003] Specifically, two liquid cooling pipes are configured at the rear of the cabinet, providing channels for the incoming and outgoing cooling liquid respectively. All server computing nodes are connected to the CDU located at the bottom of the cabinet through these two pipes. The CDU is responsible for providing secondary-side heat dissipation for the servers. However, with the upgrade of each generation of computing nodes, this design often requires redesigning and adapting to new cabinets, resulting in increased costs and waste of resources. Because the development speed of computing nodes is significantly faster than the evolution speed of cabinets, in most cases, changes to cabinets are passive adjustments made only to adapt to the needs of new computing nodes. This situation not only increases the cost of designing new cabinets, but also consumes a lot of human resources. Summary of the Invention

[0062] In the description of the embodiments of the present application, the term "plurality" refers to more than two (including two).

[0063] Related technologies point out that with the continuous advancement of AI technology, the computing power and power consumption of single GPU cards continue to grow, making effective cooling of GPU cards in servers even more critical. Currently, AI servers primarily use air cooling and cold plate liquid cooling to address this challenge. Because different GPU models have different cooling requirements, the cooling system design within each server also varies.

[0064] In terms of AI cabinet design, considering the development and changes in computing nodes (primarily GPU cards), the design of the entire cabinet must also be adjusted accordingly to adapt to new requirements. The current practice is to integrate the power supply unit, GPU server, and cooling distribution unit (CDU) into the same cabinet, and usually use cold plate liquid cooling for heat dissipation. Specifically, two liquid cooling pipes 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 at the bottom of the cabinet through these two pipes. The CDU is responsible for providing secondary side heat dissipation for the server.

[0065] However, with each new generation of compute nodes, this design often requires a complete redesign of the cabinets to accommodate them, resulting in increased costs and wasted resources. Because compute nodes are evolving significantly faster than cabinets, cabinet modifications are often made passively to accommodate the demands of new compute nodes. This situation not only increases the cost of designing new cabinets but also consumes significant human resources. Therefore, reducing cabinet production costs has become an urgent issue.

[0066] Based on the above considerations, in order to reduce the production cost of the cabinet, the applicant has designed a heat dissipation device after in-depth research. Figure 1-Figure 7 A heat dissipation device 100 according to an embodiment of the first aspect of the present application is described.

[0067] like Figure 1-Figure 7 As shown, Figure 1 A schematic diagram of a heat dissipation device provided according to an embodiment of the present application; Figure 2 A partially enlarged schematic diagram of a heat dissipation device according to an embodiment of the present application; Figure 3 A schematic diagram of a computing node in one embodiment of the present application; Figure 4 A schematic diagram of a computing node in another embodiment of the present application; Figure 5 This is a schematic diagram of a computing node in yet another embodiment of the present application; Figure 6 This is a schematic diagram of a computing node in yet another embodiment of the present application; Figure 7 This is a schematic diagram of a computing node in yet another embodiment of the present application.

[0068] According to the heat dissipation device 100 of the embodiment of the first aspect of the present application, the heat dissipation device 100 is used to dissipate heat from the computing node 200, and the heat dissipation device 100 includes: a cabinet 1, a cold distribution unit 2, a water inlet component 3 and a water outlet component 4.

[0069] Specifically, the computing node 200 is arranged in the cabinet 1, and each computing node 200 has a water inlet 201 and a water outlet 202. The cold distribution unit 2 is arranged in the cabinet 1, and the water inlet component 3 is arranged on the cabinet 1. The water inlet component 3 is connected between the cold distribution unit 2 and each computing node 200. The water inlet component 3 includes a plurality of water inlet pipes 31, and the plurality of water inlet pipes 31 extend in the vertical direction and are arranged at intervals in the first direction. The water inlet 201 of each computing node 200 is connected to at least one of the plurality of water inlet pipes 31. The water outlet component 4 is arranged on the cabinet 1, and the water outlet component 4 is connected between the cold distribution unit 2 and each computing node 200. The water outlet component 4 includes a plurality of water outlet pipes 41, and the plurality of water outlet pipes 41 extend in the vertical direction and are arranged at intervals in the first direction. The water outlet 202 of each computing node 200 is connected to at least one of the plurality of water outlet pipes 41.

[0070] It can be understood that the cabinet 1 serves as the basic structure of the entire heat dissipation device 100, and is used to accommodate the computing node 200, the cold distribution unit 2 (CDU), the water inlet component 3 and the water outlet component 4, etc. The computing node 200 is installed in 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 cold distribution unit 2 through its own water inlet 201 and water outlet 202, thereby reducing the difficulty of connecting the computing node 200 with the cold distribution unit 2.

[0071] The cold distribution unit 2 is located in the cabinet 1. The cold distribution unit 2 is used to provide power for the circulation of the refrigerant and adjust the temperature of the computing node 200. In this way, the cold distribution unit 2 transports the refrigerant to the computing node 200, and the refrigerant exchanges heat with the computing node 200. After the heat exchange, the refrigerant carrying heat flows back from the computing node 200 to the cold distribution unit 2, and the refrigerant exchanges heat again in the cold distribution unit 2 to reduce the refrigerant temperature.

[0072] The water inlet assembly 3 is located on the cabinet 1 and is used to distribute the refrigerant to the water inlet 201 of each computing node 200. The water inlet assembly 3 includes a plurality of water inlet pipes 31, each of which extends in a vertical direction. The water inlet pipes 31 extend in a first direction (such as Figure 1 The water inlet 201 of each computing node 200 is connected to at least one water inlet pipe 31. In this way, each computing node 200 can be connected to the water inlet component 3 and connected to the cold distribution unit 2, ensuring that each computing node 200 can receive a sufficient and uniform supply of refrigerant. The water inlet component 3 can adapt to computing nodes 200 of different numbers and layouts, which helps to reduce the cost of redesigning the cabinet 1 due to the replacement of computing nodes 200.

[0073] The water outlet assembly 4 is located on the cabinet 1. The water outlet assembly 4 is used to collect the refrigerant flowing out of each computing node 200 and transport the refrigerant collected by each computing node 200 back to the cooling distribution unit. The water outlet assembly 4 includes a plurality of water outlet pipes 41. Each water outlet pipe 41 extends in a vertical direction. The water inlet pipe 31 is in a first direction (such as Figure 1 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 component 4 and connected to the cold distribution unit 2, ensuring that the refrigerant in each computing node 200 flows back to the cold distribution unit 2. Therefore, the water outlet component 4 can adapt to computing nodes 200 of different numbers and layouts. The water outlet component 4 cooperates with the water inlet component 3, which helps to reduce the cost of updating the design of the cabinet 1 due to the replacement of computing nodes 200.

[0074] The working process of the heat dissipation device 100 of the present application is described below:

[0075] First, the refrigerant flows out of the cold distribution unit 2 and flows into the water inlet component 3, and then the refrigerant flows from the water inlet component 3 into the computing node 200 through the water inlet 201. The refrigerant exchanges heat in the computing node 200. After the heat exchange, the refrigerant carrying heat flows out of the computing node 200 and flows into the water outlet pipe 41 through the water outlet 202. Finally, after the heat exchange, the refrigerant carrying heat flows out of the water outlet pipe 41 and flows back to the cold distribution unit 2, thereby ensuring the heat dissipation effect of the computing node 200.

[0076] In a specific embodiment, referring to Figure 1 As shown, the computing node 200 and the cooling distribution unit 2 are both 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, the water outlet assembly 4 includes three water outlet pipes 41, the water inlet pipes 31 and the water outlet pipes 41 extend in the up and down directions, and the cabinet 1 has a first position P1, a second position P2 and a third position P3. The first position P1 is provided with an inlet pipe 31 and an outlet pipe 41, and the inlet pipe 31 and the outlet pipe 41 are arranged adjacent to each other. The second position P2 is provided with an inlet pipe 31 and a water outlet pipe 41, the water inlet pipe 31 and the water outlet pipe 41 are arranged adjacent to each other, and a water inlet pipe 31 and a 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 a different computing node 200 is 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 communicated with different computing nodes 200, and there is no need to use a longer pipe for connection, thereby ensuring that the structure of the heat dissipation device 100 is simple, easy to assemble and maintain, and reducing the difficulty of assembly and maintenance.

[0077] That is, 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 in 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 in the first position P1;

Even if the position of the water inlet pipe 31 is adjusted, it will not affect the connection between the water inlet pipe 31 and the water inlet manifold 32.

The refrigerant flows from the cold distribution unit 2 to the diverter plate 8, and then flows from the diverter plate 8 through the second connecting pipe 10 into the water inlet manifold 32. Then the refrigerant flows from the water inlet manifold 32 through the first connecting pipe 9 into the water inlet pipe 31, and finally flows from the water inlet pipe 31 through the third connecting pipe 11 and into the computing node 200 from the water inlet 201 for heat exchange.
