摘要 针对汽车动力电池在工作过程中的散热效率低下和散热不均的问题,文章对电池排布方式和散热风道进行了优化,并基于Fluent流体分析软件对方形电池和圆柱形电池的工作过程进行风冷散热仿真。仿真结果表明,方形电池采用纵向摆放散热更均匀;对于方形电池,局部风道与整体风道散热效果差别不显著,对于圆柱形电池,整体风道散热效果优于局部风道;进风口电池组在中心位置时的散热效果优于进风口在侧边位置。文章得到的不同电池排布方式和风道对电池散热的影响可为电池散热相关研究提供一定的帮助。 Aiming at the problems of low and uneven heat dissipation efficiency of automotive power battery in the working process, this paper optimized the battery layout and heat dissipation air channel. Based on Fluent software, the air cooling heat dissipation simulation of square battery and cylindrical battery was carried out. The simulation results show that the heat dissipation of the square battery is more uniform by longitudinal arrangement. For square batteries, there is little difference between the heat dissipation effect of local air channel and that of the whole air channel. For cylindrical batteries, the heat dissipation effect of the whole air channel is better than that of the local air channel. The heat dissipation effect of the air inlet battery string in the center position is better than that of the air inlet in the side position. The influence of different battery arrangement and air channel on battery heat dissipation obtained in this paper can provide some help for the research of battery heat dissipation.
