Thermal behavior of supercapacitor modules based on top cover angle
A continuous high temperature will cause a performance attenuation of the supercapacitor module(SCM),thus affecting the service life of the supercapacitor;an air cooling strategy for managing the heat of SCM was proposed by changing the angle of the top cover of the module.Based on the princi-ples of fluid-solid coupling heat transfer,the temperature of SCM under natural convection was simulat-ed by Fluent simulation software,and the reliability of the simulations verified through experiments.The influence of different angles of the top cover of SCM on its cooling effect was studied,with the re-sults showing that designing a certain angle for the top cover of SCM could effectively reduce the highest temperature and maximum temperature difference of the supercapacitor.When the cover plate angle θ=2°,compared with the horizontal cover plate,the highest temperature and maximum temperature differ-ence of SCM decreased by 2.07 and 2.68 ℃ respectively.As the angle of the top cover plate increased,the highest temperature and maximum temperature difference of SCM first decreased and then increased.
