The invention relates to the technical field of automobile parts, in particular to an automobile heat dissipation air door and an automobile heat dissipation fan. The multiple air doors are arranged on the periphery of the fan in a scattered mode, and the air outlet direction of the fan is consistent with that of the air doors. The air door comprises a door frame and a door plate, the upper portion of the door plate is pivoted to the upper portion of the door frame, and when the door plate naturally droops, the edge of the door plate is matched with the door frame in an abutting mode; a flexible layer is arranged on the edge of the door plate and matched with the door frame in a sealed mode. The flexible layer is arranged on the edge of the door plate, and when the air door is closed, the flexible layer on the edge of the door plate is in closed fit with the door frame, so that the damping and buffering functions are provided, noise generated by collision in the closing process of the air door can be reduced, and the sealing performance of the air door in the closed state can be enhanced; and when the vehicle runs at a low speed and only the fan provides cooling air, air leakage is prevented, and the energy efficiency of the fan is improved.

    本发明涉及汽车配件技术领域,具体涉及一种车用散热风门及车用散热风扇。多个风门分散布置于风扇的外周,所述风扇与风门的出风方向一致。该风门包括门框和门板,所述门板的上部与所述门框的上部枢接,当所述门板自然下垂时,所述门板的边沿与所述门框抵接配合;所述门板的边沿设有柔性层,所述柔性层与所述门框密闭配合。本发明在门板的边沿设置柔性层,当风门进行关闭时,门板边沿的柔性层与所述门框密闭配合,一是提供减震缓冲功能,可以降低风门关闭过程中撞击产生的噪音,二是可以增强风门关闭状态的密封性,在车辆低速行驶仅由风扇提供冷却风时,防止风量外泄,提升了风扇的能效。
