摘要： An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.

摘要： A fan includes a base, a motor and an impeller, and the motor includes a sleeve, a rotor, a position limiting element and a composite elastic element. The sleeve is disposed on the base, and the sleeve has a bottom portion and a side wall, which constitute an accommodation space. The rotor has a rotating shaft disposed within the accommodation space, and the rotating shaft has an outer wall. An annular groove is formed on the outer wall and has a surface. The position limiting element is disposed on the sleeve and extended from the side wall toward the rotating shaft, and the position limiting element has a bottom surface. The bottom surface faces toward the bottom portion, and the bottom surface is interfered with the surface, thereby eliminating the gap between the bottom surface and the surface. Therefore, noise of the up and down vibration is avoided from generating.

摘要： A centrifugal fan with dual outlets in the same direction includes a fan frame, an impeller, and a motor. The fan frame includes an upper cover, a base plate and a first air deflector. The base plate and the upper cover are connected to form an accommodating space and an air outlet plane. The first air deflector is arranged near the air outlet plane and divides the air outlet plane into a first air outlet and a second air outlet. The impeller is disposed in the accommodating space. The impeller and the side wall of the fan frame form a flow channel therebetween. The motor is connected to the impeller and drives it to rotate. The first air deflector extends inward of the flow channel from the air outlet plane and the end of the first air deflector has a first guide portion, which is a slanted surface.

摘要： A centrifugal fan includes a frame and an impeller. The impeller is disposed within the frame. The impeller includes a hub, a first blade group and a second blade group. The hub includes a center part, an inclined part and a connection part. The first blade group is connected with the connection part of the hub. The second blade group is disposed on the inclined part of the hub. There is a first distance between the second blade group and the first blade group. There is a second distance between the second blade group and the center part of the hub.
