摘要

对HXD1C电力机车辅助变流器用理论计算确定散热器尺寸，通过经验公式计算散热系统所需风量，用CFD软件FLUENT对风道散热系统进行了三维数值模拟分析，求解散热系统的温度场分布。通过与试验结果进行对比研究，表明计算结果满足工程运用所需的精度要求，可应用于类似系统的热分析中。

Abstract

This paper determined the size of the heat sink of auxiliary converter of HXD1C locomotive. The required cooling air volume was calculated through experience formula. Three-dimensional calculation model for duct cooling systems numerical simulation had been set up by using CFD software FLUENT, which was used to solve the temperature distribution in the cooling system. Test results compared with the study results show that the required accuracy meets the requirements of engineering application and the heat analysis can be applied to similar systems.
