The invention discloses a condensate water drainage structure, an air conditioning unit and a railway vehicle. The condensate water drainage structure comprises a water receiving device and a drainage connector connected to the water receiving device. The water receiving device is provided with an inner cavity used for receiving condensate water of the air conditioning unit. The drainage joint is provided with a water inlet port communicated with the inner cavity and a drainage port communicated with the water inlet port; the drainage port is arranged on the outer side of the water receiving device, and the section of the inner wall of the drainage port is polygonal; the sectional area of the drainage connector is gradually reduced from the first position of the drainage connector to the drainage port, and the first position is equal to or lower than the preset position of the water inlet port. According to the condensate water drainage structure, due to the arrangement of the drainage connector, when water flows to the drainage port from top to bottom, the water is full, the content of air in accumulated water is reduced when the water is drained, the tension of the water is destroyed through the polygonal inner wall section, and therefore the resistance of water drainage is reduced, the drainage speed is increased, and the water is drained smoothly in time.

    本发明公开了一种冷凝水排水结构、空调机组及轨道车辆,该冷凝水排水结构包括接水装置和连接在接水装置上的排水接头;接水装置具有内腔,用于接收空调机组的冷凝水;排水接头具有连通内腔的进水端口以及与进水端口连通的排水端口;排水端口设置于接水装置的外侧,且其内壁截面为多边形;从排水接头的第一位置至排水端口处,所述排水接头的截面积逐渐减小,第一位置为等于或低于进水端口的预设位置。上述冷凝水排水结构,通过设置排水接头,当水流从上到下流至排水端口时水流充盈,减少水流排出时积水中空气的含量,通过具有多边形形状的内壁截面破坏水流的张力,从而减小水流排出的阻力,加大排水速度,使水流及时流畅地排出。
