An auxiliary heat dissipation device for precision air conditioners in a computer room

Abstract

The invention provides a precise air-conditioning auxiliary heat dissipation device for a machine room. The precise air-conditioning auxiliary heat dissipation device for the machine room comprises a heat exchanger, a circulation water tank, a water storage tank, a water pump I, a water pump II, a magnetic valve Y, a three-way valve Y1, a three-way valve Y2 and a controller. The heat exchanger comprises a tank body and multiple spiral refrigerant pipes, spiral fins are arranged on the tank body inner side wall in a second cavity, the refrigerant pipes are arranged in the second cavity, and a liquid level sensor and a temperature sensor are arranged in the circulation water tank; the circulation water tank, the water pumps and the water storage tank are communicated with one another through the three-way valve Y1, and the circulation water tank, the heat exchanger and the water storage tank are communicated with one another through the three-way valve Y2. According to the precise air-conditioning auxiliary heat dissipation device for the machine room, the functions of auxiliary heat dissipation in summer and auxiliary heating in winter can be achieved; the heat exchange effect is significantly improved through the spiral fins in the tank body and arc-shaped fins on the refrigerant pipes; warm water in the circulation water tank can be conveyed to the water storage tank for domestic water in summer.

Description

technical field [0001] The invention relates to a cooling device for an air conditioner, in particular to an auxiliary cooling device for a precision air conditioner in a machine room. Background technique [0002] The precision air conditioning system of the computer room is an important guarantee for the safe and stable operation of the computer room of the data center. With the advent of high temperature in summer, the outdoor unit of the air conditioner is in a high temperature environment. An alarm will cause the air conditioning system to stop cooling, which will bring great hidden dangers to the safe operation of the data center computer room. At present, the measures to solve the high-voltage alarm of air conditioners at home and abroad are mostly to increase the contact area between the condenser of the outdoor unit of the air conditioner and the air, thereby improving the heat exchange capacity of the outdoor unit of the air conditioner. However, due to the space l...
