摘要

针对研制的30 t 大轴重货运机车辅助变流柜中，风冷大功率模块的功率器件IGBT 在开关过程中产生大量的热量，采用合适的冷却系统将产生的热量有效散发出去，保证产品和系统可靠、稳定地工作。通过理论计算，采用Fluent 软件对功率模块散热器全域温度场分析相结合的方式，对散热器性能加以验证和调整，使散热效果达到最佳，满足系统要求，同时大大缩短开发周期，并能有效降低研发成本。

Abstract

Cooling system was designed for 30 t heavy-axle freight locomotive auxiliary converter cabinet air-cooling high-power IGBTmodule to insure product operation stable and reliable. By combination of theoretical calculation and global temperature field analysis forpower module with Fluent, radiator performance was verified and regulated for optimal effect to satisfy system requirement, shortendevelopment cycle and reduce cost.
