摘要
由于车用锂电池在使用过程中会产生大量的热,为了使电池更好地散热,保持正常工作温度和温度均匀性,目前广泛采用强制风冷系统散热。通过应用计算流体动力学方法和流固耦合传热分析方法,自行设计风冷系统,并且对锂电池组进行WLTC循环工况下的风冷散热仿真。结果表明,采用所设计的风冷散热系统可明显降低电池组的温升,同时使电池组保持良好的温度均匀性。
Due to a large amount of heat will be generated during the use of automotive lithium batteries,in order to make the battery better heat dissipation,maintain the normal working temperature and temperature uniformity,currently,forced air cooling system is widely used for heat dissipation.By applying the computational fluid dynamics method and the fluid-solid coupled heat transfer analysis method,the air cooling system was designed by ourselves,and the simulation of air cooling and heat dissipation under WLTC working condition was carried out for the lithium battery pack.The results show that the temperature rise of the battery pack can be significantly reduced and the temperature uniformity of the battery pack can be maintained.
