Embodiment Construction
[0029] The present invention will be further described below in conjunction with specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0030] For the convenience of description, the relative positional relationship of each component, such as: the description of up, down, left, right, etc., is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.
[0031] Such as Figure 1-Figure 4 As shown, an embodiment of the air-conditioning air duct for rail transit vehicles of the present invention includes a driver's cab ventilation unit 1, a soft air duct 2, a first air duct 3, a distribution box 4, a transition air duct 5, and a second air duct 6. An air-conditioning unit is installed above the second air duct 6, and the air-conditioning unit supplies air from the transition air duct 5 to the distribution box 4. After the air passes through the distribution...

The invention discloses an air conditioner air duct for a rail traffic vehicle. The air conditioner air duct for the rail traffic vehicle comprises a first air duct (3) and a second air duct (6) whichare sequentially installed on the top of a passenger compartment of the vehicle. The first air duct and the second air duct are connected with an air supply opening of an air conditioner unit througha distributing box (4). The inner cavity of the first air duct is divided by a first partition plate (34) into a first dynamic pressure cavity (35) and a first static pressure cavity (31). The innercavity of the second air duct is divided by a second partition plate (66) into a second dynamic pressure cavity (65) and a second static pressure cavity (63). The cross section areas of the first dynamic pressure cavity and the second dynamic pressure cavity are gradually reduced in the airflow direction. The cross section areas of the first static pressure cavity and the second static pressure cavity are gradually increased in the airflow direction. The air conditioner air duct for the rail traffic vehicle improves the uniformity of air distribution of the passenger chamber and meanwhile lowers noise in the passenger chamber, and the riding comfort of the passengers in the passenger chamber is improved as a whole.
Description
technical field [0001] The invention relates to a rail passenger car ventilation device, in particular to an air-conditioning air duct for a rail transit vehicle. Background technique [0002] The air-conditioning duct is an indispensable connecting part between the air-conditioning unit and the passenger compartment of rail transit vehicles. How to reduce the airflow noise in the air-conditioning duct and use the air-conditioning duct to reduce the noise of the air-conditioning unit entering the passenger room, and at the same time improve the air-conditioning duct outlet. The uniformity of the air supply puts forward higher requirements for the structural design of the air conditioning duct. [0003] Due to the limited internal space of rail vehicles currently in use, the distance between the air-conditioning duct and the air outlet roof of the passenger compartment is very close, and the noise in the passenger compartment is relatively large; in addition, there are uneven...
