摘　　要：为了研究动力电池液冷板的散热效果,借助数值模拟的方法,针对实际工况,设置了电池放电倍率、冷却液入口温度和流速为变量,分析了液冷式电池组的散热效果。并在原有的液冷板基础上,通过改变其结构进行优化。结果显示,优化后的液冷板电池组内的温度差下降,电池组保持在一个理想状态下进行散热。In order to study the heat dissipation effect of the power battery liquid-cooled plate,this paper,by means of numerical simulation,set the battery discharge rate,coolant inlet temperature and flow rate as variables for the actual working condition,and analyzed the heat dissipation effect of the liquid-cooled battery pack.And on the basis of the original liquid cooling plate,optimize through changing its structure.The results show that the temperature difference in the optimized liquid-cooled battery group decreases,and the battery group maintains an ideal state for heat dissipation.
