Detailed Description

As shown in fig. 1 and fig. 2, the present embodiment is disposed on an HVAC assembly of an air conditioning unit, and in particular, an HVAC wind guiding structure 11 of an automobile air conditioner, including: first cold wind passageway to fourth cold wind passageway 1 ~ 4 and first warm braw passageway to fourth warm braw passageway 5 ~ 8, wherein: the cold air channel and the warm air channel are arranged adjacently, the first warm air channel 5 and the second warm air channel 6 are arranged on the shell 12 on the two sides of the air conditioning box respectively, the third warm air channel 7 and the fourth warm air channel 8 are arranged on the two sides of the middle partition plate 13 respectively, and the first cold air channel 1 to the fourth cold air channel 1 to 4 are arranged on the side of the first warm air channel 5 to the side of the fourth warm air channel 8 respectively in a corresponding mode.

As shown in fig. 3a, the first warm air passage 5 and the first cool air passage 1 are provided on the housing 12 at one side; as shown in fig. 3b and 3c, the third warm air passage 7, the fourth warm air passage 8, the third cool air passage 3 and the fourth cool air passage 4 are provided at both sides of the middle partition 13; as shown in fig. 3d, the second warm air passage 6 and the second cool air passage 2 are provided on the other side of the housing 12.

As shown in fig. 2, the first baffle plate 9a and the second baffle plate 9b are respectively disposed on the side surfaces of the first cold air channel 1 and the second cold air channel 2, and the first baffle plate 9a and the second baffle plate 9b are asymmetrically disposed, so that the ventilation width is adjusted by moving the first wall surface 1a of the first cold air channel 1 and the first wall surface 2a of the second cold air channel 2 to the middle or to the side surface, thereby enlarging or reducing the air intake area of the channels to precisely control the intake air volume of the channels.

The third cold air channel 3 and the fourth cold air channel 4 are of a tapered structure, the ventilation width is adjusted by moving the first wall surface 3a of the third cold air channel 3 and the first wall surface 4a of the fourth cold air channel 4 to the middle or the side surface, so that the air inlet area of the channels is enlarged or reduced to accurately control the air inlet amount of the channels, and in the running process of the temperature air door from full cooling to full heating, the cold air amount of the cold air channels changes in a nonlinear mode, namely the closer to the full heating position, the faster the cold air amount is reduced.

The tapered structure is as follows: the air outlet of the channel is in a trapezoid shape with a narrow top and a wide bottom.

As shown in fig. 2, 3a and 3d, the first warm air channel 5 and the second warm air channel 6 are respectively formed by the second wall surface 1b of the first cold air channel 1 and the second wall surface 2b of the second cold air channel 2 and the side casing, and the second wall surface 1b of the first cold air channel 1 and the second wall surface 2b of the second cold air channel 2 move towards the middle or the side to adjust the ventilation width, so that the air inlet area of the channels is enlarged or reduced to accurately control the air inlet amount of the channels.

The third warm air channel 7 and the fourth warm air channel 8 are in streamline structures, and the ventilation width is adjusted by moving the second wall surface 3b of the third cold air channel 3 and the second wall surface 4b of the fourth cold air channel 4 towards the middle or the side surface, so that the air inlet area of the channels is enlarged or reduced to accurately control the air inlet amount of the channels.

In the process that the temperature air door runs from full cold to full hot, the first baffle 9a and the second baffle 9b guide cold air and then shield warm air so as to control the temperature linear type.
