To provide an exhaust air passage structure of a power converter which can reduce the temperature rise in a passenger compartment.SOLUTION: An exhaust air passage structure of a power converter is the exhaust air passage structure of the power converter that is configured in such a way that the exhaust air after cooling the power converter installed in a passenger compartment by an air cooling device is discharged into the passenger compartment through a duct connected to the air cooling device. With respect to at least a portion of an exhaust air passage formed on the downstream side in the flow direction of the exhaust air relative to an outlet part of the duct, a member with the high heat insulation property is provided on the passenger compartment inner side, and a member with the high heat transfer property is provided on the passenger compartment outer side. The exhaust air passage is sandwiched by the member with the high heat insulation property and the member with the high heat transfer property.SELECTED DRAWING: Figure 2
【課題】車室内の温度上昇を低減させることができる電力変換器の排風経路構造を提供すること。【解決手段】本発明の電力変換器の排風経路構造は、車室内に設けられた電力変換器を空冷装置によって冷却した後の排風が、前記空冷装置に接続されたダクトを通って前記車室内に排出されるように構成された、電力変換器の排風経路構造であって、前記ダクトの出口部よりも前記排風の流れ方向で下流側に形成された排風経路の少なくとも一部に対して、断熱性の高い部材を車室内側に設け、伝熱性の高い部材を車室外側に設けて、前記断熱性の高い部材と前記伝熱性の高い部材とによって前記排風経路を挟み込むように構成した。【選択図】図2
