A novel closed phase-change liquid cooling server system

Abstract

The invention provides a novel closed phase-change liquid cooling server system. A compressor acquires the liquid refrigerant in the refrigerant storage tank. The liquid refrigerant is inputted to theliquid refrigerant storage area, and the liquid refrigerant in the liquid refrigerant storage area cools the immersed server; the output end of the condenser is connected with the input end of the refrigerant storage tank. The condenser converts the gaseous refrigerant into the liquid refrigerant and inputs the liquid refrigerant to the refrigerant storage tank for storage. Components inside theimmersed server will heat up during operation, and the heat causes the refrigerant liquid to boil. As the boiling proceeds, a large amount of gas is generated, a gaseous refrigerant storage area is left above the liquid level, and the gas is discharged to the condenser through the sealed space. The gas enters the condenser and condenses into liquid refrigerant through the condenser. The liquid refrigerant is fed into the refrigerant storage tank for storage, so that the cooling and pressure inside the server can be kept constant and explosion hazard can be avoided.

Description

technical field [0001] The invention relates to the field of server cooling, in particular to a novel closed phase change liquid cooling server system. Background technique [0002] The heat dissipation method of the server generally adopts the air cooling method to cool down the server. In the air-cooled mode, indirect contact cooling is adopted. Therefore, in the cooling system with complex heat transfer process, there are problems of large contact thermal resistance, large convective heat transfer thermal resistance, and large sum of thermal resistance, which leads to high heat transfer efficiency. At the same time, it is necessary to ensure a large temperature difference between the high and low temperature heat sources in the heat exchange process, so a lower outdoor low temperature heat source is required to guide the heat exchange process. However, for data centers, air cooling alone is not enough to meet the heat dissipation performance requirements of servers with ...

Problems solved by technology

When the gas reaches a certain amount, if the gas is not exhausted in time, the pressure in the sealed space will increase sharply, making the sealed space explosive.
