摘要

为了维持动力电池的性能、延长其使用寿命，应使电池模块工作过程中的温度和温差维持在适宜的范围之内。为此，提出一种新型蜂巢式液冷动力电池模块，该结构内部设有进/出口导流板且电池呈蜂巢式分布，冷却液体与电池呈360°间接接触，极大强化了换热效果。在单体电池热特性数值模拟与试验验证的基础上，通过计算流体力学平台建立新型蜂巢式液冷电池模块模型，研究了电池模块的热行为，分析了冷却液流量、冷却液温度对电池模块传热性能的影响。结果表明：（1）增加冷却液流量可显著降低电池模块最高温度，改善温度均匀性，当冷却液流量增加到1.5 L/min之后，电池模块最高温度及最大温差趋于稳定；（2）冷却液温度的降低可显著降低电池模块中最高温度，但在一定程度上恶化了模块中的温度均匀性；（3）冷却液流量和温度对电池模块的加热特性影响显著。因此，采用液冷方式是必要的。

Abstract

To maintain the performance of the power battery and prolong its service life

the temperature and temperature difference during the operation of the battery module should be maintained within an appropriate range. Thus

a new type of honeycomb liquid-cooled power battery module is proposed. The structure has an inlet/outlet guide plate inside and the battery is honeycomb-like distribution. The cooling liquid contacts with the battery indirectly at 360°

which greatly strengthens the heat transfer effect. On the basis of the numerical simulation and experimental validation of the thermal characteristics of single battery

a new model of honeycomb liquid-cooled battery module was established by computational fluid dynamics(CFD) platform

the thermal behavior of the battery module was studied

and the effects of the coolant flow rate

the coolant temperature of battery on the heat dissipation performance of the battery module were studied. The results show that: (1) Increasing the flow rate of coolant can significantly reduce the maximum temperature of the battery module and improve the temperature uniformity

when the flow rate of coolant increases to 1.5 L/min

the maximum temperature and the maximum temperature difference of the battery module tend to be stable; (2) Decreasing the temperature of coolant can significantly reduce the highest temperature of the battery module

but to a certain extent

the temperature uniformity in the battery module is deteriorated; (3) The coolant flow rate and the coolant temperature have significant influence on the heating characteristics of the battery module. Therefore

liquid cooling is necessary.
