摘要

SiC器件凭借高开关频率和低损耗的性能优势，在新一代地铁变流器中日益受到重视，并逐步得到推广应用。针对基于SiC器件的地铁变流器模块，对其走行风冷散热系统进行设计，搭建了大风道试验平台模拟走行风冷，并通过对地铁车辆底部实物建模仿真，对比验证大风道试验的可行性和准确性，同时分析了车体布局对散热性能的影响，为地铁走行风冷散热系统的设计提供指导性建议。

Abstract

With the advantages of high switching frequency and low loss, SiC devices have been paid more and more attention in the new generation of metro converters, and have been gradually popularized and applied. Aiming at SiC-device-based metro converter module, the running air-cooling system was designed, and the wind tunnel test platform was built to simulate the running air cooling. Through the modeling and simulation of the subway vehicle bottom objects, the feasibility and accuracy of the wind tunnel test were compared and verified. At the same time, the influence of the car body layout on the heat dissipation performance was analyzed, which provided guidance for the design of the subway running air cooling system.
