Data center heat dissipation system with direct connection between loop heat pipe and refrigeration cycle pipe

Abstract

The invention relates to a data center heat dissipation system with direct connection between a loop heat pipe and a refrigeration cycle pipe. The system comprises a loop heat pipe unit, a circulatingworking-medium fast joint unit, and a refrigerant circulation unit. The loop heat pipe unit includes a gas pipe, a liquid pipe, an evaporation end and a condensation end; liquid generated by condensation in the condensation end flows through the liquid pipe to the evaporation end; the evaporation end is adhered to a chip in a server; and heat generated by the chip in the server heats the liquid to generate gas by evaporation and the gas returns to the condensation end along the gas pipe. The condensation end is connected to a refrigeration cycle pipe of the refrigerant circulation unit through the circulating working-medium fast joint unit; the circulating working medium transmits the heat generated by the condensation end of the loop heat pipe unit to a condenser of the refrigerant circulation unit; and the heat is exchanged to the outdoor space by the condenser. Because of direct connection between the heat pipe and the refrigeration cycle pipe, the heat exchange link and the temperature difference loss from the chip to the refrigeration circulation are reduced; and the energy consumption and noises caused by the traditional machine room heat dissipation technology are reduced.

Problems solved by technology

Traditional computer room heat dissipation systems mainly include air cooling and liquid cooling. The air-cooled computer room cooling system mainly relies on the computer room air conditioner to reduce the indoor air temperature in the computer room, and then organizes the airflow through the built-in fans and channels in the server cabinet to make the indoor cold air enter the cabinet. Heat exchange with the server, the heat dissipation technology is relatively mature, but it consumes a lot of energy to organize the airflow and increase the heat exchange temperature difference between the server and the cold air, the noise is large, and it is easy to cause local overheating and cause downtime; the development of liquid-cooled computer room heat dissipation system is relatively relatively At present, there are various forms such as water-cooled heat dissipation at the end of the organic room air conditioner combination, immersion heat dissipation, etc., but they all face technical problems such as liquid leakage that can easily cause circuit failures and corrode components.
