| Summary: | 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. |
