风冷冲击射流与相变耦合的电池热管理数值分析OA
Numerical analysis of battery thermal management coupling with ACIJ and PCM
针对圆柱型锂电池在应用中散热均匀性差的问题,提出了一种风冷冲击射流与相变材料(PCM)耦合的热管理系统.通过数值仿真分析了喷孔排列方式、喷孔直径及风速对电池最高温度和温度均匀性的影响,并对风冷冲击射流、相变材料和风冷耦合相变系统的冷却性能进行了对比.结果表明:在风速为2 m/s、喷孔直径为4 mm,且采用case2冲击板的工况下,电池最高温度降至40.06℃,最大温差控制在1.52℃;与常规风冷耦合PCM方案相比,风冷冲击射流与PCM耦合方案的最高温度降低了1.4℃,最大温差减少了2.03℃.
In allusion to the problem of poor thermal uniformity in cylindrical lithium-ion batteries,a thermal management system coupling air-cooled impinging jet(ACIJ)and phase change material(PCM)is proposed.Numerical simulations were conducted to investigate the effects of jet hole arrangement,hole diameter,and airflow velocity on the maximum temperature and temperature uniformity of the battery.The ACIJ and PCM are compared with the performance of cooling of air-cooled coupled phase change system.The results show that under the conditions of airflow velocity of 2 m/s,jet hole diameter of 4 mm,and the use of case2 jet plate configuration,the maximum temperature of the battery was reduced to 40.06℃with the maximum temperature difference of 1.52℃.In comparison with the conventional air-cooling coupled PCM scheme,the maximum temperature of the scheme coupling ACIJ and PCM is decreased by 1.4℃,and the maximum temperature difference is reduced by 2.03℃.
