Description

Technical Field

[0001] The present invention belongs to the technical field of server liquid cooling, and in particular relates to a liquid cooling server system. Background Art

[0002] Data center servers have high requirements for heat dissipation. Traditional heat dissipation methods mainly include air-cooled computer room air conditioners, fans, and other power-consuming methods to achieve the corresponding heat dissipation requirements. First, the power consumption is high, and second, the corresponding noise is large. For servers with increasingly higher density, traditional server casings or cabinets combined with air cooling can no longer meet the server heat dissipation needs; therefore, liquid cooling server technology came into being. Its basic principle is to remove the heat generated by the heating elements in the server through a cooling medium. Compared with traditional air cooling, it has the advantages of high heat exchange density, good energy saving effect, reduced noise, and heat recovery.

[0003] Existing liquid-cooled servers, such as a liquid-cooled server cabinet, are specifically a cabinet-type structure, which adopts upper spraying and is circulated by a liquid pump in conjunction with a circulation pipeline to achieve liquid cooling. Spraying requires additional electricity and once the spraying stops, it will cause the temperature inside the cabinet to be unstable; another example is an immersion liquid-cooled server, which specifically adopts the method of directly immersing the server motherboard in the refrigerant. This method will cause the server motherboard to be oxidized by the refrigerant over a long period of time, resulting in a shortened lifespan. In addition, all servers and heating components in the liquid-cooled server are concentrated on one motherboard, and are not independent. When the motherboard is partially damaged, it will cause all servers to The server is damaged; another example is an immersed phase change rack-mounted liquid-cooled server with an upper refrigeration module, which specifically fills multiple servers with liquid separately, and the liquid refrigerant absorbs heat and then turns into gaseous refrigerant for output, and a unified refrigeration module and branch pipelines are used for liquid circulation. This technical solution is for a fixed space and size, and cannot achieve the increase or decrease of servers and the adaptability of the number of servers, and the refrigerant pipeline is complicated and has poor practicality; and the existing liquid-cooled server refrigerant uses special refrigerant or chemical liquid as the refrigerant, which is expensive and pollutes the environment.
