In the present study, the thermal behavior of a power battery cooling structure employing copper rods, and heat pipes was compared. The influences of flow rate and inlet temperature of coolant, as well as input power were discussed by numerical methods. The numerical computation results showed that heat pipe could significantly augment the heat transfer 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 temperature ratios on the battery surface, together with the heat flux as soon as streamlines around the heat pipe condenser was also illustrated.
