Cooling system of heat-pipe external-circulation type secondary coolant loop server cabinet

Abstract

The invention discloses a cooling system of a heat-pipe external-circulation type secondary coolant loop server cabinet. The cooling system comprises more than one heat-pipe cooler, the server cabinet, a water supply branch pipe, a water return branch pipe, a machine room water supply trunk pipe, a machine room water return trunk pipe, an automatic water replenishing and pressure fixing device, a circulating water pump, a reserve pump, heat exchange devices, an outdoor liquid return connecting pipe, an outdoor air outlet connecting pipe, a liquid valve, an air valve, an air cooling condenser and a control system. The air cooling condenser adopts natural-cooling and energy-saving measures. The servers can be directly cooled, and the problems of local overheat and heat points of the server cabinet are solved. Meanwhile, by means of the natural-cooling measures, heat-exchange temperature is high in difference and efficiency, and the cooling system has the advantages of simplicity, reliability and low power consumption and noise and meets the concept of energy conservation 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 heat pipe external circulation type secondary refrigerant loop server cabinet heat dissipation system. Background technique

[0002] With the continuous increase of high-density cabinets in the computer room of the IDC Internet data center, the integration of equipment is getting higher and higher, and the processing capacity is gradually increasing, but the power consumption of the equipment also increases, resulting in more heat generated by the equipment in the cabinet. According to statistics, at present, the cabinet servers in large IDC computer rooms in China generate a large amount of heat, and they basically run 8760 hours a year. For computer rooms that do not use fresh air, cooling is required throughout the year, resulting in huge energy consumption of the air conditioning system. It accounts for about 40% to 50% of ...
