| Abstract: | The heat dissipation performance of IGBT has increasingly become an important factor affecting for the safety,reliability and power performance of high-speed EMUs during driving.In this paper,the traction converter box of an export articulated vehicle is used as the experimental research carrier,and a special air cooling test bench is developed.At the same time,the simulation calculation is carried out by using the simulation software Flotherm,and the feasibility of the simulation calculation is verified through the comparative study of the physical experiment and the simulation calculation. |
