并行风冷的方形动力锂电池组温度仿真分析
|
摘要
依据锂电池发热机理,建立方形动力锂电池两种排列组合的三维模型,并使用ICEM软件对两个模型进行了网格划分。基于CFD理论,运用FLUENT仿真软件进行了热场数值计算。计算结果显示:单体的温差与排列方式相关;行排列最高温度比列排列高;风冷流场设计以列排列方式为宜。
On the basis of analyzing the heat generating mechanism of lithium-ion power battery, the three-dimensional models of two kinds of arrangements of square lithium-ion power cells for column and row was established, and the two models were meshed in grid with ICEM software. The numerical calculation was carried out by using FLUENT simulation software based on the CFD theory. The analysis results highlight the maximum,minimum temperature of column arrangement is lower than those of row arrangement. And temperature range of each cell in column arrangement is also lower than that in row arrangement. In other words, the column arrangement is superior to the row arrangement in the parallel air-cooling of the square lithium-ion power battery.
