To solve the problem of power modules local overheating a water cooling system of the power modules for electric vehicles(EVs) was developed in this paper. Three-dimensional model of a cold plate and power modules for a motor controller was built and the power losses of the power modules were calculated. The temperature field of the cold plate and the power modules are analyzed by using the engineering software of computational fluid dynamics (CFD). According to the results of the analysis we improve the structure of the cold plate. CFD simulation results show that the problem of the power module overheating to be solved by using improved the structure of the cold plate. And the overall temperature rising of the power module is also reduced, which provide a strong guarantee of the stability and the lifetime of the motor controller.
