为了强化动力电池热管理系统的性能,提高电池组的散热能力和温度一致性,提出了一种基于对角双向流道结构的液冷板新设计方案。以多排布置的方形锂离子电池组为研究对象,借鉴Bernardi生热速率模型,运用Flotherm有限元分析软件建立液冷式锂离子电池组热管理系统的CFD仿真模型,通过调节该液冷板的结构参数,对冷板结构进行优化,满足系统的散热能力和温度一致性要求。研究结果表明:该液冷板在满足散热能力的同时能够很好地控制电池组的温度一致性,电池组的最大温差为2.4℃,相较于其他两种结构形式的液冷板,其温度一致性优势明显;通过调节该液冷板中矩形流道的宽度、相关流道的间距和冷却液流动速度,散...

In order to enhance the performance of the thermal management system of power batteries,improve the heat dissipation capacity and temperature consistency of the battery pack,a new design idea(scheme)of the liquid cooling plate based on the diagonal two-way passage structure was proposed.Taking the square lithium-ion battery pack with multi row arrangement as the research object,the Bernardi heat generation rate model was used for reference,and the CFD simulation model of the thermal management system of the liquid cooling lithium-ion battery pa...
