Abstract
The utility model discloses a passenger car and an air-conditioning air return channel structure of the passenger car. Air returning ports (namely an upper air returning port and a lower air returning port) used for returning air to an air-conditioner are formed in the inner walls of an upper layer and a lower layer of the tail portion of a coach of the passenger car. Baffle plates are vertically arranged on the inner wall of the upper air returning port and the inner wall of the lower air returning port. Adjacent baffle plates are distributed oppositely at intervals. When the air-conditioning air return channel structure of the passenger car is used, the design of the upper air returning port and the lower air returning port can improve the sizes of the air returning ports on the inner walls of the coach, air in the coach is prevented from stacking at the positions of the coach air returning ports, resistance of the coach before air returning ports return the air to a channel is reduced, and therefore the goal of reducing noise in the car is achieved through enlargement the coach air returning ports. The baffle plates can enable noise generated in the channel to change direction, and therefore the noise can not be directly spread to the inner space of the coach through the channel. Namely, spread distance of the noise in the channel is added to weaken intensity when the noise reaches the inner space of the coach, and volume of the noise in the channel is further reduced.
