Simulation Analysis And Research on Heat Dissipation of Li-ion Power Battery
The heat dissipation performance of the power battery is very important for the normal operation of electric vehicles.In order to find a better heat dissipation method and improve the heat dissipation effect of the power battery,the maximum temperature and temperature difference of the power battery are taken as evaluation indexes,and the influence of different types of cold pipes and different numbers of pipes on the heat dissipation performance of the power battery is analyzed by CFD(Computational Fluid Dynamics)method.The results of orthogonal test with 4 factors and 4 levels show that the type of cold pipe and the flow rate of pipe coolant have significant effects on the results,and the best cooling scheme is selected.
