Air pressure stabilizing device applied to airtight circulation cooling system

Abstract

The invention relates to an air pressure stabilizing device applied to an airtight circulation cooling system. The device is characterized by comprising an air compressor, a first solenoid valve, a second solenoid valve, a check valve, a pressure transmitter, a manual vent valve, a safety valve, a liquidometer and a buffer tank, wherein an air outlet of the air compressor communicates with an inlet of the first solenoid valve and an inlet of the second solenoid valve simultaneously, an outlet of the second solenoid valve communicates with an inlet of the check valve, an outlet of the check valve, the pressure transmitter, the manual vent valve and the safety valve all communicates with the buffer tank, the liquidometer which communicates with the buffer tank is arranged on the buffer tank,and the buffer tank is provided with a water inlet and a water outlet. According to the device, the airtight circulation cooling system is subject to pressure stabilization through air, the problem that nitrogen is consumed in system running and requires frequent replacement is solved, the adaptability of the airtight circulation cooling system in a region, where nitrogen transport is difficult,is improved, and the application rang of the system is expanded.

Description

technical field [0001] The invention relates to an air pressure stabilizing device, in particular to an air stabilizing device used in a closed circulation cooling system. Background technique [0002] At present, the closed circulation cooling system using pure water as the cooling medium is becoming more and more widely used. This kind of equipment brings the cooling water into the electronic component radiator through the water pump for heat exchange and takes away the heat, and then passes through the external cooling water air heat exchanger. Heat exchange occurs with the environment to reduce the temperature of electronic components. However, the volume of cooling water will expand or contract with the change of temperature. If no pressure stabilization system is installed in the closed system, the pressure of the system will change drastically, which will greatly affect the stability of the closed circulation cooling system. And further affect the heat dissipation ef...
