摘要
为优化电池热管理系统热力性能,基于新型吹胀式液冷板设计了三种流道结构。利用实验和CFD仿真模拟分析对比了三种流道结构在不同入口流量、温度下液冷板的传热特性、流动特性和阻力特性,选定合适的流道形式并进一步结构优化。结果表明:优化后的吹胀式液冷板均温性得到了显著改善,与原流道结构液冷板相比,模组顶部截面温差和最大温差分别降低了0.7331和0.5634 K,电池最高温度和压降仅升高0.15 K和2.206 kPa。
In order to optimize the thermal performance of the battery thermal management system,three types of runner structures were designed based on the new roll-bond liquid cooling plate.Experiments and CFD simulations were used to compare the heat transfer characteristics,flow characteristics and resistance characteristics of the three runner structures at different inlet mass flow rates and temperatures of the liquid cooling plate,and the most suitable runner form was selected and further optimized.The results show that the liquid-cooled plate has significantly improved the temperature uniformity,and compared with the original runner structure liquid-cooled plate,the temperature difference in the top section of the module and the maximum temperature difference are reduced by 0.7331 and 0.5634 K,respectively,and the maximum temperature of the cell and the flow resistance are only increased by 0.15 K and 2.206 kPa.
