The invention provides a natural ventilator and a railway vehicle. The natural ventilator comprises an air guide barrel, an outer cover and an inner cover. The air duct is connected to a connecting flange arranged around a roof waste discharge hole in a sealed mode. The outer cover surrounds the periphery of the air duct and is connected with the air duct or/and the car roof, the bottom end of the outer cover is open, a first ventilation gap is formed between the bottom end of the outer cover and the car roof, and an air hole vertically aligned with the air duct is formed in the center of the top wall of the outer cover; the inner cover is arranged over the air guide barrel in a covering mode and connected with the air guide barrel or/and the outer cover, the circumferential edge of the inner cover extends into the outer cover from the air holes and extends to the periphery of the top end of the air guide barrel, a second ventilation gap is formed between the inner cover and the outer cover, and a third ventilation gap is formed between the inner cover and the top end of the air guide barrel. According to the natural ventilator and the railway vehicle, two ventilation paths are provided for natural ventilation towards the outside of the vehicle, so that the ventilation quantity can be multiplied, the natural ventilator is more reliable and durable in structure, vibration noise can be avoided, and the riding experience is improved.
本发明提供了一种自然通风器及轨道车辆,包括导风筒、外罩和内罩;其中,导风筒密封连接在环绕车顶废排孔设置的连接法兰上;外罩环绕于导风筒外围并与导风筒或/和车顶连接,外罩的底端开放并与车顶之间形成第一通风间隙,外罩的顶壁中心设有与导风筒上下对齐的风孔;内罩罩设于导风筒的正上方并与导风筒或/和外罩连接,内罩的周向边缘于风孔伸入外罩并延伸至导风筒的顶端外围,且内罩与外罩之间形成第二通风间隙,内罩与导风筒的顶端之间形成第三通风间隙。本发明提供的自然通风器及轨道车辆,存在两条通风路径向车外自然通风,因此能够成倍提高通风量,不仅在结构上更加可靠耐用,而且能够避免产生振动噪音,从而提升乘车体验。
