Optimization of structure of cold plate with corrugated flow channel for power battery
In response to the cooling issue of power batteries,a cold plate with the corrugated flow channel is designed by considering the layout and heat dissipation requirements of the battery module.It can regulate the temperature of the heat exchange surface while ensuring the energy consumption is kept in check,and it has good thermal uniformity.The characteristic structure of cold plate is analyzed,the impacts of peaks and troughs height,channel inlet angle and channel width on performance of the cold plate are discussed respectively.Adjusting the channel inlet angle can better control the variation in internal pressure drop through flow distribution,while the setting of channel width and peaks and troughs can improve the thermal uniformity issue of the cold plate.The corrugated flow channel cold plate,designed based on optimal parameters,exhibits an 8.4%increase in heat exchange performance compared to traditional straight channels,with only a 1.7%increase in energy consumption within the plate.
