The invention provides an external exhaust duct of a railway vehicle. An air duct of a cooling device is arranged at the bottom of an equipment compartment of the railway vehicle, a mounting hole is formed in a bottom plate of the equipment compartment, the external exhaust duct extends into the equipment compartment through the mounting hole, and the external exhaust duct extends into a set position to be in elastic sealing connection with an exhaust outlet of the air duct. The external exhaust duct can be elastically and hermetically connected to the exhaust outlet of the air duct when reaching the set position, so that the external exhaust duct can be connected to the exhaust outlet of the air duct only by moving for a set short distance in the equipment compartment, and the installation of the external exhaust duct can be suitable for the condition that the distance between the air duct and the bottom plate of the equipment compartment is limited. The invention further provides aninstallation method of the external exhaust duct of the railway vehicle, and the external exhaust duct is convenient to install.
本发明提供了一种轨道车辆的外接排风道,轨道车辆的设备舱底部设置冷却装置的风道,设备舱的底板上设置安装孔,外接排风道由安装孔伸入设备舱内,外接排风道伸入到设定的位置与风道的排风口弹性密封连接。外接排风道到达设定位置便可与风道的排风口弹性密封连接,使得外接风道只需在设备舱内移动设定的较短的距离便可实现与风道的排风口的连接,进而使外接排风道的安装可适用于风道与设备舱底板之间距离有限的情况。本发明还提供了一种轨道车辆的外接排风道的安装方法,便于安装外接排风道。
