A machine cabinet level server cooling system

Abstract

The invention discloses a cabinet-level server cooling system, comprising a compressor, an evaporator and a condenser, wherein the compressor is connected with a condenser through an electromagnetic valve, the condenser is connected with an evaporator through an expansion valve, the evaporator is connected with an input end of the compressor through a gas-liquid separator, and a liquid reservoir is arranged between the condenser and the expansion valve. The compressor sucks the low-pressure steam from the evaporator into the compressor, and the refrigerant enters the condenser with higher pressure and temperature through the compression work of the compressor. In the condenser, the high-temperature and high-pressure refrigerant vapor condenses into low-temperature and high-pressure liquid;The refrigerant enters the evaporator and absorbs heat and vaporizes to reduce the heat generated by the server equipment after passing through the expansion valve and turning into a low temperatureand low pressure vapor-liquid mixture. Through evaporation temperature control technology and air-conditioning bypass technology, the purpose of improving the cooling reliability of the server is achieved, through the different height of the cabinet evaporator with different degrees of refrigeration, that all the servers in the cabinet temperature is the same is ensured.

Description

technical field [0001] The invention relates to the field of server heat dissipation, in particular to an efficient rack-level server cooling system. Background technique [0002] With the rapid development of mobile data, cloud computing and big data services, the scale of data center construction is getting larger and larger, the density of single cabinets is increasing, and the heat generated by server equipment chips is also increasing. Traditional micro-module data centers only have a single closed cooling system Aisles or closed hot aisles, especially in the case of only closed cold aisle air conditioner bottom air supply, the temperature of the airflow will continue to rise in the direction of the height of the cabinet after the air is blown out of the porous floor, resulting in poor cooling effect of servers at high places in the cabinet. Uniformity of server cooling within a rack requires a rack-level server cooling system. Contents of the invention [0003] The ...
