A control method for heat pipe secondary refrigerant loop server cabinet heat dissipation system

Abstract

The invention discloses a control method for a heat pipe secondary refrigerant loop server cabinet cooling system. The system comprises one or more heat pipe radiators, a server cabinet, a water supply branch pipe, a water return branch pipe, a machine room water supply main pipe, a machine room water return main pipe, an automatic water replenishing constant pressure device, a circulating water pump, a standby water pump, a heat exchange device, an outdoor refrigerant return connecting pipe, an outdoor air outflow connecting pipe, a refrigerant valve, an air valve, an air-cooled condenser and a control system. Natural cooling energy-saving measures are adopted in the air-cooled condenser. By the adoption of the control method, a server can be directly cooled, and the problems that a server cabinet is partially too hot and hot spots exist are solved; meanwhile, the natural cooling measures are utilized, the heat exchange temperature difference is large, efficiency is high, and the system has the advantages of being simple, reliable and low in power consumption and noise and meets the ideas of energy saving and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for Internet data center cabinet services, in particular to a control method for a heat pipe secondary refrigerant loop server cabinet heat dissipation system. Background technique [0002] With the continuous increase of high-density cabinets in the IDC Internet data center computer room, the integration of equipment is getting higher and higher, and the processing capacity is gradually increasing, but the power consumption of the equipment is also increasing, resulting in more heat generated by the equipment in the cabinet. According to statistics, at present, the cabinet servers in large-scale IDC computer rooms in China generate a lot of heat, and basically run 8760h throughout the year. It accounts for about 40%~50% of the overall energy consumption of the data center. [0003] Traditional data room air supply methods include floor air duct air supply, hot and cold aisle isolation a...
