In order to improve the heat dissipation performance of IGBT module,a short groove and a flow limiting progressive cavity block are added to the conventional cooling tank.The software STAR-CCM+is used to establish a three-dimensional physical model,and the simulation calculation is conducted on IGBT module radiator before and af-ter optimization.The results show that the maximum temperature of heat source of IGBT module decreases from 39.90 ℃ to 35.96 ℃,and the average temperature decreases from 38.49 ℃ to 35.39 ℃,with a decrease of 9.9％and 8.6％,and the heat dissipation perform-ance is enhanced.With the increase of inlet mass flow rate of cooling water tank,the aver-age temperature,maximum temperature and pressure drop of cooling water tank of IGBT module heat source increase gradually.Therefore,the inlet mass flow rate of cooling water tank should be set at 0.10 kg/s for better heat dissipation effect and more economical operation of the heat dissipation system.
