Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling servers, in particular to an emergency device for a liquid cooling server cabinet. Background Art

[0002] A liquid-cooled server is a server system that uses liquid cooling technology to reduce the server temperature.

[0003] Compared with traditional air cooling systems, liquid cooling servers have many advantages:

[0004] 1. High heat dissipation efficiency. Liquid-cooled servers use liquid cooling technology to directly transfer heat from server components to the coolant, and then dissipate the heat through the radiator, which is more efficient than air cooling systems.

[0005] 2. Low energy consumption. Since liquid-cooled servers can dissipate heat more effectively, they can lower the operating temperature of the server, reduce the load on the fan, and have lower energy consumption.

[0006] 3. Low noise. Compared with the traditional air cooling system, the liquid cooling server has lower noise.

[0007] 4. High performance. By lowering the server operating temperature, liquid-cooled servers can improve server performance and stability, reducing performance degradation or failures caused by overheating.

[0008] 5. Small space. Liquid-cooled servers are more compact in design and do not require a large number of cooling fans, which can save rack space.

[0009] In a liquid-cooled data center, multiple liquid-cooled servers in each liquid-cooled server cabinet are connected in parallel to a branch pipe. When the branch pipe needs to be repaired or replaced, all liquid-cooled servers on the branch pipe need to be shut down, which not only seriously reduces the working efficiency of the liquid-cooled servers, but also frequently starts and shuts down and shortens the service life of the liquid-cooled servers.

[0062] Within a preset time period, the liquid-cooled servers in the emergency liquid-cooled server cabinet are connected to the branch pipes of the liquid-cooled server cabinet emergency device.

[0063] Since the liquid-cooled server has a hot-swappable function, the liquid-cooled server only needs to be connected to the branch pipe of the water supply module within a preset time period.

[0064] In the embodiment of the present specification, the preset time period may be 3 seconds to 5 seconds.

[0065] The emergency method for the liquid cooling server cabinet provided in the embodiment of this specification is further described as follows:

[0066] When the branch pipes of multiple liquid-cooled servers in parallel in the liquid-cooled server cabinet need to be repaired or replaced, the liquid-cooled server cabinet emergency device is placed near the liquid-cooled server cabinet with the branch pipe that needs to be replaced; the circulating water pump 7 in the liquid-cooled server cabinet emergency device is started, and the pressure and flow displayed by the pressure changer 13 and the flow transmitter 14 are observed to see whether they are within the preset range; if the pressure and flow displayed by the pressure changer 13 and the flow transmitter 14 are within the preset range, the workload of the emergency liquid-cooled server cabinet is determined, and then the expected temperature control rate of the emergency liquid-cooled server cabinet is determined according to the workload; according to the expected temperature control rate of the emergency liquid-cooled server cabinet, it is determined that the refrigeration capacity of the liquid-cooled server cabinet emergency device is larger. Observe whether the pressure displayed by the first pressure detector 15 and the second pressure detector 17 is within the preset range. If the pressure displayed by the first pressure detector 15 and the second pressure detector 17 is within the preset range, disconnect the branch pipe connected to the liquid-cooled server and the branch pipe 8 of the liquid-cooled server cabinet emergency device; when the original branch pipe is repaired or a new branch pipe is obtained, disconnect the connection between the liquid-cooled server and the branch pipe 8 of the liquid-cooled server cabinet emergency device, and connect the liquid-cooled server to the repaired or new branch pipe; finally, close the water outlet pipe of the water supply module of the liquid-cooled server cabinet emergency device and the refrigeration module.

[0067] The liquid-cooled server cabinet emergency device provided in the embodiment of this specification can ensure that the liquid-cooled server does not need to be shut down when the branch pipe connected to the liquid-cooled server fails or needs to be replaced, which not only improves the working efficiency of the liquid-cooled server, but also ensures the service life of the liquid-cooled server.

[0068] The liquid-cooled server cabinet emergency device of the embodiment of the present specification includes two refrigeration modules with different cooling capacities. The two refrigeration modules can be used separately or together, thereby being able to cope with liquid-cooled server cabinets with different workloads.
