Air conditioner air outlet channel of railway vehicle

Abstract

The invention discloses an air conditioner air outlet channel of a railway vehicle. The air conditioner air outlet channel of the railway vehicle comprises a branch air channel with two ends respectively connected with a main air channel and the air outlet channel. A mounting seat horizontally stretching out is welded on a stand pillar of a side wall. The air outlet channel is placed above the mounting seat. A plurality of air outlets are evenly and lengthways formed on the side wall of the air outlet channel away from the stand pillar of the side wall. The inside and the outside of the air outlet channel are respectively provided with a first limiting piece and a second limiting piece which are fixed on the mounting seat. The upper portion of the second limiting piece is provided with an inserting groove used for mounting an internally-mounted side top plate, the lower portion of the second limiting piece is provided with a bend which is inserted in the inserting groove at the upper end of an internally-mounted side wall plate, and an air supply corresponding to the air outlet is lengthways formed in the middle of the second limiting piece. Because the side top plate, the side wall plate and the air outlet channel are organically combined and are reasonably connected and arranged, the air conditioner air outlet channel of the railway vehicle guarantees space maximization inside passenger rooms and improves vehicle-taking comfort of passengers. The air conditioner air outlet channel of the railway vehicle can guarantee that airflow inside the passenger rooms is well organized, and meanwhile temperature fields and airflow velocity fields inside the passenger rooms reach standard requirements, can satisfy uniformity of air support airflow inside the passenger rooms, and avoid dead space.

Description

technical field [0001] The invention relates to an air outlet duct for an air conditioner of a rail vehicle, belonging to the technical field of rail vehicles. Background technique [0002] With the vigorous development of rail transit in recent years, the user's requirements for ride comfort have gradually increased, which has brought a lot of challenges to the design of passenger cars. [0003] Existing passenger car air conditioners mostly use the air supply mode on the roof side, and the wind is sent from the main air duct to the secondary air duct, and then enters the interior of the passenger compartment. The secondary air duct of the air conditioner is hoisted under the roof frame, occupying a large space in the car, affecting the appearance of the car and ride comfort, and the air supply outlet is close to the middle of the vehicle, so the uniformity of the air supply air flow is not good, and there are dead air supply angles. Contents of the invention [0004] Th...
