FIG. 1 shows an air conditioning module 900 . The air conditioning module 900 is a part of the automobile air conditioning system. The air conditioning module includes an air inlet, an air outlet, an air duct and a plurality of dampers 90 . The air duct communicates with the air inlet and the air outlet. A plurality of dampers 90 are provided in the air duct for controlling and regulating the airflow in the air duct.

Figures 2A, 2B, 3, and 4 show a damper 90 in one embodiment, which is plate-like in shape. The damper 90 includes a wall surface 1 for guiding the airflow F and a plurality of protruding ribs 2 arranged on the wall surface 1 and arranged along the first direction D1, wherein two adjacent protruding ribs 2 define a channel 3 on the wall surface 1; the channel 3. Allowing the airflow F to flow; the convex rib 2 extends along the second direction D2 on the wall surface 1, and the convex rib D2 includes a plurality of protrusions 4 separately arranged on the wall surface 1; wherein, in the same convex rib 2, adjacent ones The two protrusions 4 define a gap 5 on the wall 1 ; the gap 5 communicates with the channel 3 .

2B, 4 and 6, since the gap 5 is in communication with the channel 3, when the airflow F in the channel 3 flows to the gap 5, a part f of the airflow F (for example, the airflow flowing near the side wall of the protrusion 4) ) will flow into the gap 5, and generate a vortex 6 in the gap 5, thereby reducing the flow rate of the airflow F, thus reducing the noise generated by the friction between the airflow F and the wall surface 1 of the damper 90, therefore, the air conditioning module provided by the present utility model The damper 90 has the advantage of generating low noise.

In the embodiment not shown in the drawings, the protruding ribs 2 can be provided on the wall surfaces 1 on both sides of the plate-shaped damper 90 . The plate-shaped damper 90 is generally used as a mixing damper or a mode damper in the air conditioning module 900 .

Another damper 90 is shown in FIGS. 5A and 5B. Compared with the plate-shaped damper, the damper 90 has a more complicated spatial configuration. In the air-conditioning module 900 , it is usually used to switch the airflow F entering the air-conditioning module 900 between fresh air and return air. The damper 90 may be provided with the rib 2 only on the wall surface 1 located on the inner side thereof.
