Rock wool 15 is arranged inside each of the plurality of punching plates 10. An exhaust component is arranged at one end of the air duct body 1 for dissipating heat inside the vehicle body. A flipping component is arranged inside one end of the air duct body 1 for assisting the exhaust component to exhaust and preventing liquid and other objects from entering the inside of the air duct body 1. The plurality of punching plates 10 are stably installed inside the air duct body 1 through the connecting brackets 11, and rock wool 15 is installed inside each of the plurality of punching plates 10, so that the noise is absorbed into the inside through the rock wool 15, thereby achieving noise reduction. Since two portions are installed inside the air duct body 1, the range of noise treatment and absorption is increased, and the noise is greatly reduced.
[0035] Refer to Figure 1 , Figure 2 and Figure 6 , the exhaust component includes a fan housing 5. The fan housing 5 is fixedly connected to the inside of the air duct body 1. A driving motor two 20 is fixedly connected to the side of the fan housing 5. An impeller 21 is rotatably connected to the inside of the fan housing 5. The output end of the driving motor two 20 is fixedly connected to the side of the impeller 21. An air inlet 7 is opened on one side of the fan housing 5. An air outlet pipe 8 is fixedly connected to the inside of the fan housing 5. A sieve plate 6 is fixedly connected to the inside of the fan housing 5 for preventing dust and small objects from entering the fan housing 5. By running the driving motor two 20 to drive the impeller 21 to rotate, the heat energy inside the vehicle can enter from the air inlet 7 and be discharged into the inside of the air duct body 1 from the air outlet pipe 8 under the drive of the wind generated by the rotation of the impeller 21. Under the operation of the exhaust component, the wind carrying heat energy is discharged outside the air duct body 1.
[0036] Refer to Figure 2 , Figure 3 and Figure 5, the flipping component includes a driving motor 13. The driving motor 13 is fixedly connected to the inner side of the air duct body 1. The output end of the driving motor 13 is fixedly connected with a round wheel rod assembly 18. A second connecting rod 19 is slidably connected to the outside of the round wheel rod assembly 18.

Concave plates 4 are fixedly connected to the outer sides of both ends of each of the plurality of third connecting rods 23. A louver 3 is fixedly connected to the inside of each of the plurality of concave plates 4. While driving the round wheel rod assembly 18 to rotate through the operation of the driving motor 13, the second connecting rod 19 drives the first fixing block 17 to move up and down. While the first fixing block 17 moves up and down, it drives a plurality of connecting blocks 16 to rotate. Since one end of each of the plurality of connecting blocks 16 is fixed to the side of the third connecting rod 23, the third connecting rod 23 drives the concave plate 4 and the louver 3 to rotate, thereby assisting the exhaust component to discharge the wind carrying heat energy outside the air duct body 1. The louver 3 is fixedly connected to the inside of the third connecting rod 23 to prevent liquid and small objects from entering the inside of the air duct body 1. A baffle 2 is fixedly connected to the outer side of one end of the air duct body 1 to prevent sunlight and rainwater from damaging the louver 3.

Drain ports 14 are provided at both ends of the water accumulation tank 9 to discharge the rainwater collected inside the water accumulation tank 9 outside the air duct body 1.
[0037] Working principle: By operating the driving motor 20 to drive the impeller 21 to rotate, the heat energy in the vehicle is led to enter from the air inlet 7 and be discharged into the air duct body 1 through the air outlet pipe 8 under the wind force generated by the rotation of the impeller 21. Under the operation of the exhaust component, the wind carrying heat energy is discharged outside the air duct body 1. The plurality of punching plates 10 are stably installed inside the air duct body 1 through the connecting bracket 11. Rock wool 15 is installed inside each of the plurality of punching plates 10, so that the noise is absorbed into the inside through the rock wool 15, thereby achieving noise reduction. Since two portions are installed inside the air duct body 1, the range of noise treatment and absorption is increased, and the noise is greatly reduced. While driving the round wheel rod assembly 18 to rotate through the operation of the driving motor 13, the second connecting rod 19 drives the first fixing block 17 to move up and down. While the first fixing block 17 moves up and down, it drives a plurality of connecting blocks 16 to rotate. Since one end of each of the plurality of connecting blocks 16 is fixed to the side of the third connecting rod 23, the third connecting rod 23 drives the concave plate 4 and the louver 3 to rotate, thereby assisting the exhaust component to discharge the wind carrying heat energy outside the air duct body 1.
