摘　　要：通过CFD分析软件进行仿真分析,研究了电池组风冷结构对流场与温度场分布的影响,并由温度实验验证了该风冷结构的冷却效果。此种结构提高了电池组内部温度场均匀性。电池组在1 C充放电条件下,电池组内部测量点温度在294～296.8 K,同一时刻测量点温差在2 K以内。The effect of the air cooling structure on distribution of flow field and temperature field was studied through simulation by CFD software. The effect of air cooling structure was proved by the temperature experiment. The structure improves the temperature uniformity of the battery pack.At 1 C charge-discharge rate, the inner temperature of metrical points ranged from 294 K to 296.8 K, and the temperature difference was less than 2 K at the same time.
