Embodiments of the present invention are described in detail below with reference to figures 1-7:

an air-conditioning duct structure of a multi-compartment type track tourist car comprises a first car duct and a rear car duct, wherein the first car duct and the rear car duct are shown in figures 1-3 and 5 and 6 respectively, each of the first car duct and the rear car duct comprises a wind guide duct 1 and a plurality of blowing ducts, each blowing duct is a reducing duct with the inner diameter gradually reduced along the wind flow direction M from the wind guide duct 1, the wind guide duct 1 and a first blowing duct 201 communicated with the wind guide duct 1 are provided with a return duct 3, each return duct 3 comprises a rectangular groove located at the wind guide duct 1 and a triangular groove 4 located at the first blowing duct 201, and compared with a flat groove, each triangular groove 4 can reduce wind resistance and improve return efficiency; an oblique rectangular air return pipe is arranged in the rectangular groove, the rectangular groove is set to be of an oblique rectangular structure, the space occupied by the air return pipe can be saved, the air return area is increased, and meanwhile, the integral length of the air return pipe can be adjusted according to the size of the installation space and the air return length by adjusting the angle between the inclined plane in the oblique rectangular air return pipe and the horizontal line L; as shown in fig. 7, an included angle α between the inclined surface of the first inclined rectangular return air duct 5 on the primary vehicle and the horizontal line L is larger than an included angle β between the inclined surface of the second inclined rectangular return air duct 6 on the secondary vehicle and the horizontal line L, and the return air length of the first inclined rectangular return air duct 5 on the primary vehicle is larger than the return air length of the second inclined rectangular return air duct 6 on the secondary vehicle.

As shown in fig. 1-3, the primary vehicle air duct further includes an air supply duct 7 located between the air guide duct 1 and the first air blowing duct 201, the air supply duct 7 is provided with a second rectangular groove 302 communicated with the rectangular groove, and the first oblique rectangular return duct 5 extends from the inside of the first rectangular groove 301 to the inside of the second rectangular groove 302. Because the head car comprises a driver area A and a passenger area B, the length of the first inclined rectangular return air pipe 5 can be increased by arranging the air supply duct 7, so that the first inclined rectangular return air pipe 5 extends from the driver area A to the passenger area B, air return can be carried out above the passenger area B by arranging an air conditioner in the driver area A of the head car lane, air is pumped back to the air conditioner in the driver area A by the first inclined rectangular return air pipe 5, and the air blowing requirements of the driver and the passengers can be met only by arranging the air conditioner in the driver area A; if the air supply duct 7 is not arranged, because a certain distance exists between the driver area A and the passenger area B, when one air conditioner is arranged in the driver area A, the return air duct of the driver area A is difficult to draw the air at the passenger area B back into the air conditioner of the driver area A, and the air conditioning effect in the passenger area B is poor, then one air conditioner is required to be arranged in the passenger area B to meet the air blowing requirement of passengers in the head car; this scheme need not alone again to install the air conditioner in passenger district B, has reduced the limitation to air conditioner mounted position, has saved the cost, can improve the air conditioning effect in first car lane, and driver and passenger all can enjoy better air conditioner effect of blowing. Meanwhile, the included angle alpha between the inclined plane of the first inclined rectangular air return pipe 5 and the horizontal line L is larger, and the occupied space of the first inclined rectangular air return pipe 5 can be reduced while the air return length is longer.

The air duct structure of the rear vehicle is shown in fig. 6 and 7, the inclined plane of the second inclined rectangular air return duct 6 has a smaller included angle beta with the horizontal line L, the air return length of the second inclined rectangular air return duct 6 is shorter, and the air conditioner air blowing requirement of all passengers in the whole carriage can be met by occupying a smaller space.

As shown in fig. 1-4, the first oblique rectangular return air duct 5 on the head car further includes a first air inlet duct 8, which is located on the first oblique rectangular return air duct 5 and has a downward opening close to the triangular trough 4, and a second air inlet duct 9, which is located above the first air inlet duct 8 and has an upward opening far from the triangular trough 4, and the return air area is increased by the first air inlet duct 8 and the second air inlet duct 9. The first air inlet pipe 8 and the second air inlet pipe 9 are both rectangular air inlet pipes, and the height H1 of the first air inlet pipe 8 is greater than the height H2 of the second air inlet pipe 9; when the first oblique rectangular air return pipe 5 returns air, air in the closed space is sucked into the air conditioner through the first air inlet pipe 8, the height H1 of the first air inlet pipe 8 is set to be larger than the height H2 of the second air inlet pipe 9, so that the cavity in the first air inlet pipe 8 is large in volume, the air return area is large, and the air return efficiency can be improved.

As shown in fig. 1 and 5, the angle γ of a side angle of the triangular groove 4 opposite to the return air groove 3 is 30 ° to 50 °. When gamma is too large, such as more than 50 degrees, the wind resistance is large, and the air return efficiency is poor; when γ is too small, e.g., less than 30 °, the return air efficiency will also be affected due to too much wind velocity in the duct. Therefore, when the gamma is set to be 30-50 degrees, the air return efficiency can be improved while the small wind resistance is ensured. In order to ensure the best air return effect, the present embodiment preferably sets γ to 40 °.
