摘要

在这项研究中，使用波纹冷却通道和 Al2O3-Cu/water 混合纳米流体的冷却系统被用作棱柱形锂离子电池的电池热管理系统 (BTMS)。基于有限元方法建立的计算模型在不同雷诺数下使用固体体积分数从 0% 到 2% 不等的混合纳米流体。冷板呈波纹状，在棱柱形锂离子电池单元之间有各种方形凹槽。随着固体纳米粒子体积分数和波纹冷却通道数量的增加，最高温度也随之降低。在比较冷却通道数量最少和最多的情况下，发现使用水时最高温度降低了 3.07 K，而使用 Al2O3-Cu/ 水混合纳米流体时（固体体积分数最大时）最高温度降低了 1.86 K。在使用固体体积分数最高的纳米流体时，冷却通道中的方形凹槽数量对温度下降没有显著影响。

THERMAL MANAGEMENT OF LITHIUM-ION BATTERY PACKS BY USING CORRUGATED CHANNELS WITH NANO-ENHANCED COOLING

In this study, a cooling system using corrugated cooling channels and Al₂O₃−Cu/water hybrid nanofluid is offered as the battery thermal management system (BTMS) for prismatic Li-ion batteries. A computational model built based on the finite element approach uses hybrid nanofluid at solid volume fractions ranging from 0 to 2% at various Reynolds numbers. The cold plates are corrugated and have a variety of square grooves positioned between prismatic Li-ion battery cells. The maximum temperature decreases as the volume fraction of solid nanoparticles and the number of corrugated cooling channels increases. When cases of using lowest and highest number of cooling channels are compared, maximum temperature reduction is found as 3.07 K when using water and 1.86 K when using Al₂O₃−Cu/water hybrid nanofluid (at the largest solid volume fraction). The number of square grooves in the cooling channels does not have any significant impact on the temperature drop when using nanofluid at the highest solid volume fraction.
