The invention discloses a two-way ventilation blower for an automobile air conditioner. The two-way ventilation blower for the automobile air conditioner comprises an impeller (1) and a motor (2) located on the axis of the impeller (1), and the motor (2) is installed on a motor mounting plate (3) located at the bottom of the impeller (1); the motor mounting plate (3) is fixed on a shell of the impeller (1), multiple ventilation openings (4) are formed in the motor mounting plate (3), a chamfer (7) is arranged on the edge of the side, near the impeller (1), of each ventilation opening (4), and impeller chamfers (6) are arranged on the edge of the side, near the ventilation openings (4) of the impeller (1); a partition plate (5) is arranged in the middle of the impeller (1), and the partition plate (5) divides the impeller (1) into an upper section and the lower section. By means of the two-way ventilation blower for the automobile air conditioner, noise produced by cutting a mounting plate opening through a blade can be effectively reduced, noise produced by air recirculation can be effectively reduced, and the efficiency of the impeller is improved.
