Study on cold plate of high power electric drive controller

Abstract

With the rapid development of global electric transmission technology, the problem of the heat dissipation is becoming more and more prominent for vehicle high-power controllers, which seriously affects the normal work and the reliability and then becomes an inevitable bottleneck problem for the development of controllers. Based on the heat dissipation problem of high-power electric drive controllers, a cold plate of controller with high power and high heat flux is developed to meet vehicular environmental conditions through the structure design, performance optimization, simulation and experimental research method of combining. The error between performance test and simulation of cold plate is controlled at about 3%, which verifies the feasibility and effectiveness of the design, optimization method and the simulation calculation method of cold plate and also provides the corresponding technical support and technical reserves for electric vehicles.
