摘　　要：为解决传统通道型液冷板功耗高、散热效率低等问题,提出了用于电动车的一种异形化的水轮形扰流翅片组耦合均温板电池热管理系统。水轮组的组合方式、布置位置和数量等因素确定基础模型后,使用多目标优化方法,分析了翅片长度、翅片倾角、中心距离出口边距离和两出口间距离。为了进一步提升液冷板均温性,在液冷板外侧添加均温板,以温度为目标函数对其进行拓扑优化。结果表明:与初始模型相比平均温度和标准差分别降低了1.83℃和0.45,综合评价指标—热性能因子(TPF)提升77.8%。翅片长度、倾角、出口位置及其附件扰流对液冷板各项性能有着显著影响。在流体通道所占体积分数为0.8时,液冷板的平均温度进一步下降2.6℃,温度标准差下降0.206,TPF相较添加前继续提升18.9%。A special-shaped thermal management system of hydrothermal chamber batteries coupled with spoiler fin groups was proposed for electric vehicles(EV)to solve the problems of the high-power consumption and the low heat dissipation efficiency of traditional channel-type liquid cold plates.A multi-objective optimization method was used to analyze the fin length,the fin inclination,the distance between the center and the exit edge,and the distance between the two outlets after a basic model was determined by discussing the combination mode,arrangement position,and number of water wheel sets.the average temperature decreases 1.83℃with a standard deviation of 0.45 compared with the initial model.The comprehensive evaluation index,thermal performance factor(TPF),increases 77.8%.The results show that the fin length,the angle,the outlet arrangement,and its accessory turbulence have significant effects on the liquid cooling-plate performances.The liquid cooling-plate average-temperature further decreases 2.64℃with a temperature standard-deviation decreasing 0.206,and a TPF increasing18.9%compared with the cooling-plate without the temperature homogenization plate when the fluid-passage volume-fraction is 0.8.
