Thermal Performance of Heat Pipe Array in Battery Thermal Management

In the present study, the thermal performance of a power battery cooling system using copper tubes and heat pipes was compared. The effects of coolant flow rate, coolant inlet temperature, and input power were discussed by numerical methods. The numerical computation results showed that heat pipe could more significantly enhance the heat transfer performance of the battery cooling system than the copper rod. Within the scope of this study, the heat pipe reduced the maximum temperature by 41,6% - 60,9%. The distributions of the temperature ratio of the battery surface, together with the heat flux and streamlines around the heat pipe condenser were also illustrated.
