CPCM/液冷式锂电池组散热系统优化设计

Optimization design of heat dissipation system for CPCM/liquid cooled lithium battery pack

笔者基于相同结构特征的圆形带翅片冷却流道,以流道整体厚度、翅片数量、圆形带翅片冷却流道横截面积为因素,电池组最高温度和最大温差为优化目标,进行正交试验、数值模拟。结论认为:铝制冷却流道的横截面积是对电池组散热影响最大的因素。

In this paper,based on the circular cooling channel with fins with the same structural characteristics,taking the overall thickness of the channel,the number of fins and the cross-sectional area of the circular cooling channel with fins as the factors,and the maximum temperature and maximum temperature difference of the battery pack as the optimization objectives,the orthogonal experimental numerical simulation is carried out.The conclusion is that the cross-sectional area of the aluminum cooling channel is the most important factor affecting the heat dissipation of the battery pack.
