A high-speed motor train unit aluminum alloy car with a condensate water drainage structure comprises a bottom frame (1), a car roof (2), side walls (3), and end walls (4). Water drainage notches (6) are formed in four corners of an air conditioner frame (5) of the car roof, and used for draining condensate water in a cavity in the car roof. Water drainage holes (8) are formed in joints between the side walls and side beams (9) of the bottom frame, and used for draining condensate water gathered into cavities of the side walls by profiles into an interlayer of a floor. Water drainage grooves (10) communicated with the cavities are formed in the bottoms of end wall plates. Water drainage holes (11) are formed in the end walls. A plurality of water drainage holes (12) is formed in the floor of the bottom frame, and used for draining the condensate water in the interlayer of the floor. The drainage structure ensures that the condensate water in the cavities of the car and the condensate water in the interlayer of the floor in the car can be drained out of the car in time, snow can be prevented from entering the cavities of the car, frost cracks can be effectively prevented from being caused by the condensate water to aluminum profiles of the car, and meanwhile interior decoration and cables of the car are prevented from being damaged by the condensate water. |
