Cooling system of data center machine room

Abstract

The invention provides a heat dissipation system of a data center machine room. The heat dissipation system comprises heat collection modules, a gas-liquid separator, a liquid storage tank, a heat dissipation device and a fluid working medium, wherein the heat collection module, the gas-liquid separator, the liquid storage tank and the heat dissipation device form a heat dissipation circulating pipeline, the fluid working medium flows in the heat dissipation circulating pipeline, and the collection module comprises an evaporation section, a fluid inlet pipeline, a fluid outlet pipeline, a control mechanism, an induction mechanism and a steam branch pipeline. According to the invention, the data center machine room automatically switches the heat dissipation mode and the working mode to take away the heat generated by the evaporation end of the heat collection module according to the outdoor temperature condition and the thermal load condition of the machine room by taking energy consumption minimization as a target during operating; the flow is automatically adjusted through the flow self-strain mechanism of the heat collection module so as to solve the problem of heat production difference between the heat collection modules in the cabinet; and the refrigeration cycle, the gravity-driven self-cycle and the pump-driven two-phase flow cycle share a radiator array.

Description

technical field [0001] The invention patent relates to the field of thermal management. More specifically, the patent of the present invention relates to a heat dissipation system for a data center computer room. Background technique [0002] The integration density of cabinet servers in the data center computer room is getting higher and higher, and the calorific value is also increasing accordingly. The PUE (Power Usage Effectiveness, power usage efficiency) value has become a relatively popular measure of data center power usage efficiency in the world. The PUE value refers to the ratio of all energy consumed by the data center to the energy consumed by the IT load. The closer the PUE value is to 1, the higher the greenness of a data center. At present, the PUE value of foreign advanced data center computer rooms is usually less than 2, while the PUE value of most data centers in my country is between 2-3. Therefore, the 1W power consumption of the chip-level main equi...
