Liquid cooling system of server

Abstract

The invention discloses a liquid cooling system of a server. The system comprises a sealed housing, wherein a server mainboard and a cooling liquid immersing the server mainboard are accommodated at the lower part of the sealed housing; a first cooling apparatus used for cooling the cooling liquid from the lower part of the sealed housing is arranged at the upper part of the sealed housing; a first pressure sensor is further arranged at the upper part of the sealed housing; a second pressure sensor in communication connection with the first pressure sensor and a controller in communication connection with the second pressure sensor are arranged outside the sealed housing; and the controller is in communication connection with a first valve and a second valve, and is used for controlling the opening and closing of the first valve and the second valve so as to control the internal pressure of the sealed housing to be within a predetermined pressure range. According to the liquid cooling system, the pressure sensors and the controller are arranged in and outside the sealed housing, so that the internal pressure of the liquid cooling system can be automatically maintained, the server can be effectively refrigerated, and the sealing reliability of the housing is protected.

Description

technical field [0001] The present invention relates to the field of liquid cooling systems, in particular to a liquid cooling system for servers. Background technique [0002] Most of the computers currently in use rely on cold air to cool down the machine, but in data centers, air cooling alone is not enough to meet the heat dissipation requirements of high heat flux density servers. Water cooling or liquid cooling has two major advantages: first, it directs the coolant directly to the heat source, rather than indirect cooling like air cooling; second, compared with air cooling, the heat transfer efficiency per unit volume is as high as 3500 times. Water-cooled radiators appeared in the market around 2008. Server giants such as HP and IBM and other companies focusing on data center technology have successively launched water-cooled heat dissipation products. [0003] At present, most of the refrigerants used in liquid-cooled servers on the market are water. Water with im...

Problems solved by technology

In a general liquid cooling system, once the server motherboard starts running and the liquid cooling system starts to work, as the refrigerant boils and the temperature rises, the internal pressure of the liquid cooling system will rise accordingly, which cannot be maintained at normal pressure all the time. state

Moreover, once there is a pressure difference between the inside and outside of the shell of the fully submerged liquid-cooled server, it will bring challenges and adverse effects on the sealing of the shell.

[0006] For the above-mentioned problems in related technologies, no effective solution has been proposed yet
