For the vehicle thermal management system requirement of electric vehicle, a thermal storage exchanger by using phase change materials （PCM） was studied by CFD. The numerical calculation was made through a three-dimensional PCM model in randomly packed. The characteristics of fluid flow and heat storage was analyzed. The results show that the process of phase change can be analyzed by thermal storage exchanger model with PCM ball in randomly packed.
