The invention provides a waste discharge ventilator, a waste discharge ventilation system and a railway vehicle. The waste discharge ventilator comprises a ventilator body fixedly connected to the outer top wall of a carriage, and a waste discharge channel and a flow guide channel are formed in the ventilator body; the bottom wall of the ventilator body is provided with a waste discharge air inlet communicated with the waste discharge channel, and the waste discharge air inlet is communicated with a compartment waste discharge port in an aligned mode. The waste discharge channel extends to at least one side wall of the ventilator body in the middle of the ventilator body in the width direction of the carriage and forms a waste discharge air outlet. The flow guide channel forms a flow guide air inlet on the side wall of the ventilator body towards the advancing direction of the carriage, and forms a flow guide air outlet on the side of the waste exhaust air outlet; the flow guide channel is used for guiding airflow to pass through when the compartment advances and forming negative pressure around the flow guide air outlet. According to the waste discharge ventilator, the waste discharge ventilation system and the railway vehicle, the running wind resistance and wind noise of the carriage can be reduced, and the energy saving performance of the waste discharge ventilation system is improved.

    本发明提供了一种废排通风器、废排通风系统及轨道车辆,包括固定连接在车厢外顶壁的通风器本体,通风器本体内部具有废排通道和导流通道;其中,通风器本体的底壁设有与废排通道连通的废排进风口,废排进风口与车厢废排口对齐连通;废排通道于通风器本体的中部沿车厢宽度方向延伸至通风器本体的至少一个侧壁并形成废排出风口;导流通道在通风器本体朝向车厢前进方向的侧壁上形成导流进风口,导流通道于废排出风口的侧方形成导流出风口;导流通道用于在车厢前进时引导气流通过并在导流出风口周围形成负压。本发明提供的废排通风器、废排通风系统及轨道车辆,能够降低车厢行驶风阻和风噪,提高废排通风系统的节能性。
