研究了平板热管应用到电池热管理系统的可行性,将平板热管与冷夜结合构建了动力电池热管冷却系统,利用CATIA建立了冷却系统三维模型,利用Fluent对电池组进行热仿真。在不同环境温度、放电倍率、冷却液流速条件下,分析了电池组的温度变化以及电池温度分布情况。结果表明:使用平板热管的电池组在2。5C放电倍率下,电池最高温度在40℃以下、最大温差5℃以下;在1C放电倍率下,与不含平板热管的模块相比,电池热管冷却系统最高温度和最大温差分别降低了8。19℃和7。46℃。
Research on Heat Dissipation Performance of Power Batteries Based on Flat Heat Pipes
The feasibility of applying flat heat pipes to thermal management systems of batteries was studied,and a heat pipe cooling system of power batteries was constructed by combining flat heat pipes with cooling liquid.A three-dimensional model of the cooling system was established using CATIA,and a thermal simulation of the battery pack was conducted using Fluent.The temperature changes and temperature distribution of the battery pack were analyzed under different environmental temperatures,discharge rates,and cooling liquid flow rates.The experimental results show that the battery pack using flat heat pipes has a maximum temperature below 40℃and a maximum temperature difference below 5℃at a discharge rate of 2.5 C.At a discharge rate of 1 C,compared with those of modules without flat heat pipes,the maximum temperature and maximum temperature difference of the heat pipe cooling sys-tem of the battery are reduced by 8.19℃and 7.46℃,respectively.
