摘要
介绍了高速动车主变流器冷却器工作原理,研究了其热管式空气冷却器的传热特性,掌握机车IGBT功率模块冷却器在正常运行过程中的散热量和基板温度的工作范围,为散热器的选型和设计提供了科学依据。
Operation principle of high-speed EMUs main converter cooling device was introduced.Heat-transfer character of heat-pipe air-cooling device was studied,and heat dissipating capacity and base-plate temperature range of IGBT cooling device in normal operation were obtained,which provided basis for radiator selection and design.
