锂电池蜂窝形叉状流道冷板散热研究
Research on heat dissipation of cold plates with honeycomb and fork channels of lithium batteries
摘要
Abstract
To effectively enhance the temperature uniformity of cylindrical lithium-ion batteries,this study proposes an innovative honeycomb-branching channel cold plate.A numerical simulation method was used to develop a cooling model for cylindrical lithium-ion battery packs,incorporating this unique cold plate design.The study focused on two critical factors affecting cooling performance:coolant temperature and channel branch angle.Performance comparisons were also made with two other designs,the honeycomb-serpentine channel cold plate and the planar serpentine channel cold plate,for a comprehensive evaluation.Results demonstrated that the honeycomb-branching channel cold plate effectively minimized the maximum temperature difference within the battery pack,especially under high coolant temperature conditions.The branch angle of the channels was found to weakly affect the peak temperature of the battery pack,offering flexibility in design options.Furthermore,compared to the honeycomb-serpentine and planar serpentine channel cold plates,the honeycomb-branching channel cold plate significantly lowered both the peak temperature and the maximum temperature difference of the battery pack,all while reducing energy consumption.This design proved especially effective in cooling high heat generation regions within the battery electrodes,making it a promising solution for thermal management systems seeking improved cooling performance and energy performance.关键词
