Research on Cooling Performance of Liquid Cooling Plate Based on a Battery Pack

文章基于STAR CCM+软件对挤压铝型材液冷板冷却性能进行分析,以分析结果为依据进行液冷板的优化设计。通过改变流道宽度和流道形状,模组的最高温度由34.1℃降低到33.1℃,最低温度由26.3℃降低到25.9℃,分别降低1℃和0.4℃;模组温差由7.8℃降到7.2℃,显著提升液冷板的冷却性能,有效降低模组的温度差异,为提高动力电池的安全性,延长使用寿命以及挤压铝型材液冷板结构优化提供参考。

This study analyzes the cooling performance of extruded aluminum profile water-cooled plates based on the STAR CCM+software and optimizes the design of liquid cooled plates based on the analysis results.By changing the width and shape of the flow channel,the highest temperature of the module decreased from 34.1℃to 33.1℃,and the lowest temperature decreased from 26.3℃to 25.9℃,a decrease of 1℃and 0.4℃respectively.The temperature difference of the module has decreased from 7.8℃to 7.2℃.The cooling performance of the liquid cooling plate has been significantly improved,effectively reducing the temperature difference of the module.This provides a reference for improving the safety of power batteries,extending their service life,and optimizing the structure of extruded aluminum liquid cooling plates.
