An air cooling strategy for the supercapacitor thermal management system with an oblique inlet was proposed.Based on the heat transfer principle of fluid-solid coupling,the temperature of the module under natural convection was simulated by Comsol simulation software,and the authenticity and reli-ability of the simulation verified by experiments.The influence of the inlet angle of the structure on the cooling effect of the supercapacitor module was simulated and analyzed,and the conclusions drawn.The results showed that an appropriate angle could significantly reduce the maximum temperature and maxi-mum temperature difference of the supercapacitor module.When the inlet angle was 45°,the maximum temperature and maximum temperature difference of the supercapacitor were reduced by 7％and 26％,compared with the right-angle air inlet.The change trend of the maximum temperature and maximum temperature difference of the supercapacitor was of"M"type,as the inlet angle increased from small to large.
