Abstract
The utility model provides a heat dissipation system of a data center, and relates to the technical field of cooling. The heat dissipation system comprises an air cooling circulation loop, hot airflow generated by the data center is sucked into an evaporator through an air return opening and forms cold air through heat exchange of a liquid refrigerant in the evaporator, and the cold air is guided to a cold channel of the data center through an air supply opening; according to the liquid cooling circulation loop, a gaseous refrigerant flowing out of the evaporator is transmitted to the plate heat exchanger through a refrigerant inlet, the plate heat exchanger conducts heat exchange on the gaseous refrigerant flowing in through cooling liquid flowing through the plate heat exchanger, a liquid refrigerant is formed, and the liquid refrigerant is transmitted to the evaporator through a refrigerant outlet. The cooling liquid branch comprises a cooling liquid input pipeline and a cooling liquid output pipeline, the cooling liquid input pipeline is communicated with the cooling liquid inlet of the plate heat exchanger, and the cooling liquid output pipeline is communicated with the cooling liquid outlet of the plate heat exchanger. The heat dissipation system is used for reducing heat dissipation energy consumption of the data center.
