Hydrostatic testing system and method for water-cooling converter

Abstract

The invention discloses a hydrostatic testing system and method for a water-cooling converter. The system comprises a water circulation cooling device, a water supply pipe, a return pipe, a tested device and an exhaust valve; the water supply end of the water circulation cooling device is connected with the water supply end of the tested device through the water supply pipe, the water outlet end of the tested device is connected with the return end of the water circulation cooling device through the return pipe, the exhaust valve is installed on the return pipe, a main water inlet valve is arranged at the end, close to the water circulation cooling device, of the water supply pipe, and a main water outlet valve is arranged at the end, close to the water circulation cooing device, of the return pipe; a pressure testing pump is arranged on the side, far away from the water circulation cooling device, of the main water inlet valve arranged on the water supply pipe. The hydrostatic testing system and method have the advantages that pressure testing can be conducted rapidly and efficiently by utilizing existing devices and pipelines of an existing water circulation cooling system, all the devices are controlled through valves, pipe burst and water spray phenomena caused by excessive pressure can be effectively prevented, and test conversion between a hydrostatic test and a water circulation temperature-rise test can be conducted conveniently.

Description

technical field [0001] The invention relates to the field of testing and testing of water-cooled variable-flow devices, in particular to a hydraulic test system and method of a water-cooled variable-flow device. Background technique [0002] In recent years, power electronic technology has developed rapidly, especially high-power power electronic equipment has developed rapidly in recent years. The technology and structure of the device itself have new requirements for the cooling system, so more and more water-cooled heat dissipation methods are applied to the cooling system of the power converter device. Considering the requirements of voltage level and safety insulation, pure water or deionized water circulating cooling system is generally selected as the heat dissipation cooling system of the power electronic converter. [0003] The pressure test of the water system is a necessary condition and step to ensure the normal operation of the water cooling system of the conve...

AI Technical Summary

Problems solved by technology

The rated pressure of the circulating deionized water cooling equipment used in general tests is 0.2-0.45Mpa. If the pressure test is only carried out with the aid of the deionized water circulation system, the test pressure cannot meet the requirements.

If other water system equipment with higher pressure is used, not only the original circulating water system cannot be used, but also the experimental equipment and test costs will increase significantly
