The invention relates to a motor train unit window air returning structure. The motor train unit window air returning structure comprises an air returning way located on a train roof, branch air returning ways are formed at intervals in the upper portion of the side wall in a train longitudinal direction, air returning branch pipes extending out towards the two sides are arranged on the portions, on the branch air returning ways, of the air returning way, the upper ends of the branch air returning ways are connected with the air returning branch pipes of the air returning way through flanges or clamping hoops, and the lower ends of the branch air returning ways are installed below a side top steel structure in a suspended mode through connecting pieces. According to the motor train unit window air returning structure, the branch air returning ways are arranged on side wall windows of passenger rooms of a motor train unit. The branch air returning ways are arranged on the side wall windows of the passenger rooms of the motor train unit, air after treated by an air conditioning unit is sent out from a top plate, part of the air is exhausted out of the train from a waste exhausting device of an electrical cabinet, the other part of the air returns into the unit from the air returning way on the windows, and the airflow organization of the whole passenger rooms is more complete.
Description
technical field [0001] The invention relates to an air return structure on the window of an EMU, and belongs to the technical field of return air inside rail vehicles. Background technique [0002] At present, the EMUs are all equipped with air return ducts on the roof, but the return air outlets of the air return ducts are all arranged at the end of the vehicle. The air can only be returned at the end. If the air volume is large, the wind speed will exceed the standard and the noise will be large, which affects the comfort of the ride. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a return air structure on the window of the EMU. [0004] In order to solve the above technical problems, the air return structure on the window of the EMU provided by the present invention consists of: an air return duct located on the roof, which is characterized in th...
