电动汽车动力电池组相变材料冷却的数值模拟
|
摘要
为了进一步优化动力电池组相变冷却方式的冷却效果,设计了一种相变材料耦合冷却结构。在利用实验数据验证数值模拟模型准确可靠的基础上,对相变材料冷却结构与相变材料耦合冷却结构的冷却效果进行了稳态与非稳态数值模拟。模拟结果表明:相变材料耦合冷却结构比相变材料冷却结构有更强的冷却能力,其冷却效果好,电池温度均匀性更好,在高放电倍率下表现得更明显。
In order to further optimize the cooling effect of the power battery pack phase change material cooling method, a phase change material coupling cooling structure is designed. Based on the accuracy and reliability of numerical simulation model validated by the experimental data, the steady-state and unsteady-state numerical simulation of the cooling effect of the phase change material cooling structure and phase change material coupling cooling structure are carried out. The simulation results show that the phase change material coupling cooling structure has a stronger cooling capacity than the phase change material cooling structure, the cooling effect and the cell temperature uniformity are improved, furthermore, the performance is more obvious at high discharge rate.
