Abstract (en)
A diagonal flow fan, comprising an airflow duct (8), a motor (6), an impeller (2), a blade (4), an airflow guide ring (1) and a hub (3); one end of the airflow guide ring (1) is connected to the airflow duct (8); the blade (4) and the hub (3) are located inside the impeller (2); one end of the blade (4) is connected to the hub (3), and the other end is connected to the impeller (2); the motor (6) is located inside and connected to the hub (3); the other end of the airflow guide ring (1) is located at an inner side of the impeller (2), and a gap exists between the airflow guide ring (1) and the impeller (2); a motor shaft matches the impeller (2), employing a concentric positioning configuration; and a balance component (9) is fixedly installed at a peripheral surface of the impeller (2), thereby achieving dynamic balancing. The diagonal flow fan has a compact structure and a dramatically improved overall efficiency.
