Test platform of water-cooling plate

Abstract

The invention discloses a test platform of a water-cooling plate. The test platform of the water-cooling plate comprises a main circulation pump, the water-cooling plate to be tested, a first ball valve, a water-water heat exchanger, and a liquid storage tank, wherein the main circulation pump, the water-cooling plate to be tested, the first ball valve, the water-water heat exchanger, and the liquid storage tank are connected in sequence to form a main circuit, a water inlet pressure transmitter is arranged on a water inlet of the water-cooling plate to be tested, and a water outlet pressure transmitter is arranged on a water outlet of the water-cooling plate to be tested. The test platform of the water-cooling plate further comprises a control and protection system based on programming of a programmable logic controller (PLC). The test platform of the water-cooling plate is capable of testing heat dissipation capacity of the water-cooling plate, measuring differential pressure and flow resistance at different flow rates and different temperatures, carrying out pressure testing on the water-cooling plate to be tested, and testing tightness of the water-cooling plate to be tested.

Description

technical field [0001] The invention relates to a water cooling plate, in particular to a performance testing platform of the water cooling plate. Background technique [0002] As the power density of power electronic devices increases, the cooling of power electronic devices is the biggest problem. The cooling method is also developing from air cooling to heat pipe and water cooling. At present, water cooling is the most mature cooling method for high-power power electronic devices. The water-cooled plate is the most commonly used water-cooled radiator. Before the application, it is necessary to test the pressure difference and water resistance of the internal pipes of the water-cooled plate to confirm whether it meets the design requirements. Chinese patent 202256224U discloses a water-cooled test device for IGBT modules. The test device includes a constant temperature water tank, a water pump, a filter, a water cooling plate, a module for simulating the heating conditio...

AI Technical Summary

Problems solved by technology

This device can only simply test the pressure difference of the water-cooled plate under the condition of a single flow rate and temperature, and there is no pressure test device, so it is impossible to perform a leak test on the water-cooled plate. In addition, the test device does not include a control system, and the degree of automation is low
