The train equipment compartment ventilation and heat dissipation device comprises a ventilation opening formed in an end plate of an equipment compartment, a filter screen and a tray, the filter screen and the tray are arranged between a bottom plate and a top plate of the equipment compartment, a plurality of ventilation blades are installed at the ventilation opening, and each ventilation blade rotates in the ventilation opening when subjected to wind pressure; limiting rods used for limiting the rotation amplitude of the ventilation blades are further arranged at the ventilation openings. The device has the advantages that the ventilation efficiency of the equipment cabin and an external flow field is greatly improved, and the aerodynamic resistance of a train is reduced.
本发明公开了一种列车设备舱通风散热装置,包括开设在设备舱端板上的通风口和设置在设备舱底板与顶板之间的滤网及托盘,通风口处安装有若干通风叶片,各通风叶片受风压时在通风口内转动,通风口处还设置有用于限制通风叶片转动幅度的限位杆。具有大幅增加了设备舱与外流场的通风效率,低列车的气动阻力的优点。
