摘　　要：为减缓超级电容器模组(SCM)因高温引起的性能衰减,提升超级电容器的使用寿命,提出一种改变模组顶端盖板角度的SCM热管理系统的空气冷却策略.基于流-固耦合的传热原理,用Fluent仿真软件模拟了自然空气对流下SCM的温度,并通过实验验证仿真结果的可靠性.研究SCM顶端盖板不同角度对模组冷却效果的影响.结果表明,SCM顶端盖板呈一定角度设计时,能够有效降低超级电容器的最高温度和最大温差.当盖板角度θ=2°时,相较于水平盖板,SCM的最高温度及最大温差分别下降2.07和2.68℃.随着θ由小变大,SCM的最高温度和最大温差先变小,后变大.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 principles of fluid-solid coupling heat transfer,the temperature of SCM under natural convection was simulated 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 results 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 angleθ=2°,compared with the horizontal cover plate,the highest temperature and maximum temperature difference 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.
