Problems solved by technology

Once the heat exchanger is put into operation again, there will be a high conductivity alarm, which will affect the operation of the closed circulating water cooling device and the cooled components
In addition, if the shutdown time is too long, the water in the air-water heat exchanger will dry up, resulting in damage to the fins

Abstract

The invention discloses a sealed circulation water cooling device with a conductivity protection function. The device comprises a main circulation loop and a deionization branch. The main circulation loop comprises a main circulation pipe, an electric three-way valve, an air-water heat exchanger and an apparatus to be cooled. The deionization branch comprises an ion tank and a buffer tank. The deionization branch and the main circulation loop interflow at an inlet of the main circulation loop, a bypass is arranged on the main circulation loop, and a normally-open ball valve is installed on the bypass, so that cooling media still exist in the main circulation loop to flow through the normally-open ball valve and the air-water heat exchanger when the electric three-way valve is closed, cooling water in an outer tube of the air-water heat exchanger and in the air-water heat exchanger can be maintained in a flow circulation state during the sealed circulation water cooling device operation for purification, and ultrahigh conductivity alarming caused by stopping of the air-water heat exchanger due to the closing of the electric three-way valve is prevented effectively.

Description

technical field [0001] The invention relates to a closed circulating water cooling device, in particular to a closed circulating water cooling device with conductivity protection function. Background technique [0002] With the development of electronic technology, the performance of electronic equipment has improved rapidly, and the power dissipation of the entire system has also increased sharply. The increase of power dissipation and the requirement of miniaturization lead to the increasingly prominent problem of heat dissipation. If this problem cannot be solved well, it will not only affect the performance of the equipment, but also shorten the life of the equipment. Research has shown that among the many factors that affect the reliability of electronic devices, heat dissipation is critical. The heat generated by the operation of high-power semiconductor devices will cause the temperature of the chip to rise. If there are no proper heat dissipation measures, the tempe...
