Abstract
In response to the challenges associated with uneven temperature distribution in square lithium ion batteries,this paper proposes a parallel serpentine liquid cooling channel structure and evaluates its heat dissipation performance in comparison with traditional serpentine channel struc-tures and conventional parallel channel structures.By analyzing the effects of three factors—namely,the mass flow rate of the coolant at the inlet,the inlet temperature,and the thickness of the liquid cooling plate—on the heat dissipation performance of the parallel serpentine channel structure,and employing orthogonal experiments and range analysis,this study ranks the significance of these three influencing factors to ascertain the optimal parameter combination.The research findings indicate that the heat dissipation performance of the optimized parallel serpentine channel structure is signifi-cantly enhanced,with the maximum temperature difference of the battery pack reduced by 63.9％and the pressure drop decreased by 7.7％in comparison to the original model.This study serves as a reference for the development of thermal management systems that offer improved heat dissipation performance and reduced energy consumption.关键词
