The invention discloses an air exchange structure capable of opening and closing an air outlet automatically. The air exchange structure is composed of a top cover (1), a water blocking ring (2), a middle ring assembly (3), a rotating cover assembly (4), a fan assembly (5) and an air outlet opening and closing assembly (6). The water blocking ring (2) and the middle ring assembly (3) are arranged between the top cover (1) and the rotating cover assembly (4). The top cover (1) and the rotating cover assembly (4) are closely combined through sealing glue and a screw. The fan assembly (5) is fixed in the middle ring assembly (3). The air exchange structure is characterized in that the air outlet opening and closing assembly (6) is fixed to the top cover (1) and located on the lower side of the fan assembly (5) and corresponds to the outer edge of a blade on the fan assembly (5). According to the air exchange structure, the position of the air outlet is greatly heightened, the area of the air outlet is great, and use under various working conditions can be met. When a vehicle stops running, the air outlet is automatically closed through electronic control, and key parts in the vehicle can be well protected.
