摘要
根据充电机功率模块的热流密度及温升确定了充电机的冷却方式,并提出了充电机的散热设计方案。通过散热仿真计算,计算了充电机各关键元器件温升,计算结果表明该散热设计方案满足散热需求。同时,通过温升试验对充电机整机进行了温升测试及内循环优化设计,试验结果显示增加内循环风道可有效降低充电机功率模块各元器件表面温度。
The cooling method of charger is determined according to heat flux and temperature rise of power module of charger,and the thermal design scheme for charger is provided.Via thermal simulation calculation,the temperature rise of key components and parts on charger is calculated,and the calculation result shows the thermal design scheme meets its demand of thermal.Meanwhile,the temperature rise test is conducted for the complete charge via temperature rise test and the optimization design of internal circulation is carried out.The test result shows adding internal circulation air duct can effectively reduce the surface temperature of each component and part of power module of charger.
