Abstract

Abstract

A novel symmetric serpentine channel structure was proposed for battery module thermal management. Numerical simulations were performed to investigate the bottom heat dissipation performance of a 1×6 series-connected prismatic battery module, compared against a straight-channel liquid cooling plate. The effects of the symmetric serpentine flow channel were investigated by adjusting structural parameters such as the number of channels, branch channel width, and secondary flow structure. Results show that increasing the channel numbers can enhance heat dissipation, but significantly increase the pressure drop in the inlet and outlet. Increasing the branch channel width can effectively improve the heat dissipation performance. The shortened secondary flow structure yields superior performance among the tested configurations. Specifically, the design with five channels, 24 mm branch width, and a shortened secondary flow structure reduces the maximum temperature difference and pressure drop by 23.84% and 59.02%, respectively. The proposed design outperforms the straight-channel plate in both temperature uniformity and pressure drop characteristics.
