Abstract

The invention provides a function-integrated air duct structure for rail vehicles and rail vehicles. The air duct structure includes an air duct main body and several ventilation supports; wherein, the top of the air duct main body is provided with two The air inlets arranged at intervals in the length direction of the main body, the two air inlets are used to communicate with the air-conditioning unit of the rail vehicle; the ventilation bracket has a side opening and communicates with the inner cavity of the air duct main body, and the ventilation bracket is set On the top of the air duct main body, it is used to offset against the heat preservation structure in the vehicle body and form a ventilation gap for the airflow in the vehicle to pass through. The air duct structure of the present invention can solve the problem of high noise at the bottom of the existing return air duct, and can avoid the phenomenon of excessively high local wind speed.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, in particular to a function-integrated air duct structure for rail vehicles and a rail vehicle. Background technique [0002] Due to the large number of subway vehicles and small limits, the load power and air volume requirements of the air-conditioning system are large, usually two air-conditioning units are installed at 1 / 4 and 3 / 4 of the subway vehicle, and the same cross-section air-conditioning unit is installed along the entire length of the vehicle. road. In addition, the inner surface of the car body is usually provided with a body cold-proof structure to protect the vehicle from cold and heat, and the space between the car body and the top of the air duct is basically occupied by the cold-proof structure. [0003] The air conditioning unit generally adopts the structure of returning air in the middle and supplying air on both sides. The air supply duct is generally installed...
