A heat pipe external circulation type secondary refrigerant loop server cabinet heat dissipation system

Abstract

The invention discloses a server cabinet heat dissipation system of a heat pipe external circulation type secondary refrigerant loop circuit, which comprises more than one heat pipe radiator, server cabinet, water supply branch pipe, return water branch pipe, machine room water supply main pipe, machine room return water main pipe, automatic water replenishment Pressure device, circulating water pump, standby water pump, heat exchange device, outdoor liquid return connecting pipe, outdoor air outlet connecting pipe, liquid valve, air valve, air-cooled condenser and control system; the air-cooled condenser adopts natural cooling energy-saving measures. The invention realizes the direct cooling of the server and solves the problems of local overheating and hot spots in the server cabinet; at the same time, the natural cooling measures are used, the heat exchange temperature difference is large, the efficiency is high, the characteristics are simple and reliable, low power consumption, and low noise, and the energy saving and environmental protection are met. idea.

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 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 isolat...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a heat pipe external circulation type secondary refrigerant loop server cabinet heat dissipation system, aiming to solve the problem that the existing computer room air-conditioning equipment uses outdoor air as the cold source, which makes it difficult to ensure the cleanliness and humidity of the indoor air and utilize heat exchange The cost of indirect heat exchange between the device and the outdoor cold air is high, and the maintenance workload is large
