电动赛车电池箱通风冷却结构设计方法及应用

Design Method for the Forced-air Cooling Structure of Battery Box and Its Application on Electric Power-driven Racing Car

为解决严重影响电动赛车性能的电池箱通风冷却结构复杂、质量重及散热速度缓慢等问题,采用以空气为介质的电池箱通风冷却结构先确定散热器的性能参数,并结合流体仿真分析软件(Fluent)模拟电动赛车的行驶工况,从而有效地优化电池箱通风冷却结构。采用该结构的电动赛车参加了2013年首届中国大学生方程式电车大赛(简称FSEC),顺利完成所有比赛项目并获得全国总成绩第2名。结果表明,此结构仿真分析与实际运用基本吻合。

In order to solve the problems such as the complicated forced-air cooling structure, the huge weight and tile low heat dissipation speed of the battery box that severely impact the performance of power-driven electric car, the forced-air cooling structure of the battery box taking air as the medium is employed. Attention is paid to figuring out the performance parameter of the radiator and then to simulating the driving condition of the electric car in combination with the Fluent software so as to optimize the forced-air cooling structure of the battery box. The electric car equipped with this structure has accomplished all competition events to achieve the second highest total score in the first Formula Student Electric China （FSEC） in 2013. It is proved that the simulation analysis on this structure is basically consistent with the actual condition.
