摘要
以某款畅销电动汽车所搭载的软包锂电池为对象,优化设计了一种夹持式液冷板散热器。在确定内部流道走向布置基础上,基于正交试验设计方法,借助相关CFD软件研究分析了冷却液流速V,流道数N,流道宽度W,流道高度H对液冷板散热性能和压降表现的影响。根据正交试验设计和仿真计算结果确定了液冷板优化结构,并检验相关性能。结果表明,在优化结构的散热工作下,该电池处于合理的温度区间内,且温度梯度优异,所以优化完成。基于上述优化结果对交替流向布置方案进行了研究,分析了流向对于液冷板工作性能的影响。经过对比发现,采用交替流向方案能够使电池获得更为优良的工作温度环境,这为工作温度范围和梯度要求更高的电池的液冷板设计提供了参考。
A kind of clamped liquid cooling plate was designed and optimized for a pouch battery used in a popular electric vehicle.Based on the fixed layout,the influence of coolant flow velocity V,channel number N,channel width W,channel height H on the heat dissipation and pressure drop performance of the liquid cooling plate was analyzed with the help of CFD software based on the orthogonal test design method.According to the results of orthogonal experiment design and simulation calculation,the structure of liquid cooling plate was determined and its relative performance was tested.Results showed that the battery was in a reasonable temperature range and the temperature gradient was excellent with the optimized structure,so the optimized design was completed.Furthermore,the alternate flow direction scheme was studied and the influence of the flow direction on the working performance of the liquid cooling plate was analyzed.By comparison,it was found that the alternate flow scheme could make the battery obtain a better operating temperature environment,which provides a reference for the design scheme of the liquid cooling plate for the battery with higher operating temperature range and gradient requirements.
