摘要
针对水下航行器的锂电池组发热问题,利用ANSYS Icepak软件对不同散热条件下的电池舱段内温度气流分布情况进行了仿真分析。结果表明:相比于舱内空气自然对流冷却,使用风冷散热可大幅降低电池组平均温度,并改善电芯之间的温差,有利于提高电池组的环境适应性和放电功率,进而提升水下航行器的安全性和可靠性。
Aiming at the heating problem of lithium battery pack of underwater vehicle,the ANSYS Icepak software is used to simulate and analyze the temperature and airflow distribution in the battery compartment under different heat dissipation conditions.Results shows that compared with the natural convection cooling of the cabin air,the wind-cooling can greatly reduce the average temperature of battery pack and improve the temperature difference between the cells,which is conducive to improving the environmental adaptability and discharge power of lithium battery pack,thereby enhancing the safety and reliability of underwater vehicle.
