针对动力电池模组工作过程中易出现高温且单体间温差较大的问题，设计了3种内部不同构造孔的液冷板及2种液冷板放置方式进行电池模组数值计算，考察模组电芯的温度分布情况，并通过实验验证了热仿真模型的准确性。研究发现：在相同入口截面积及流量条件下，内部长圆形孔的液冷板冷却作用要略优于圆形和椭圆形孔的液冷板；模组底部及两侧冷却方式要远优于单纯底部冷却，模组整体温度分布低且均匀性更高。
Abstract：Aiming at the problem of high temperature and large temperature difference in the operating of power battery module, three kinds of liquid cooling plate with different internal structure and two kinds of liquid cooling plate layout were designed by numerical simulation,in order to study the temperature distribution of battery module. The accuracy of thermal simulation model was verified by experiments. The results show under the same inlet cross-sectional area and flow rate, the cooling effect of the liquid cooling plate with inner long circular hole is slightly?better than that of the liquid cooling plate with circular and oval hole. The cooling mode at the bottom and both sides is much better than that at the bottom of the single module, and the temperature distribution of the module is lower and the uniformity is higher.
