| 摘 要： | 采用数值方法对电动汽车快充模式下的液冷板散热特性进行模拟,设计四种水力半径相同、截面形状不同的弓形冷板槽道,研究不同流动特征下液冷板槽道截面特性对电动汽车快充模块散热的影响,结果表明:在相同水力半径条件下,弓形通道液冷板截面特征对冷板散热特性影响很大,且散热强弱顺序随Re增大发生转变,Re<265时,矩形(4×12mm)截面散热最好;Re>265时,方形通道截面散热最好。此外,各工况下圆形通道散热效果均表现为最差。

| Abstract: | The heat dissipation characteristics of the cold plate for the fast charging module of electric vehicle were investigated by using numerical methods.Four kinds of cold plates with the same hydraulic radius were designed.The effects of cross-section characteristics of the cold plate on the heat dissipation for the fast charging module of electric vehicle were studied.The results show that the cross-section characteristics of cold plates have a great influence on the heat dissipation of the fast charging modulebased on the same hydraulic radius.The heat dissipation intensity changes with the increasing of Re.When Re<265,the heat dissipation of the rectangular channel(4×12mm)is the best,otherwise the square channel is the best.In addition,the heat dissipation effect of circular-section channel is the worst under all conditions. |
