Abstract: A fan impeller includes a hub, a shaft, a metal housing and a plurality of blades. The outer periphery of the hub has a curved surface. The shaft is disposed in the hub and connected to the hub. The metal housing has an annular shape and is disposed in the hub. A magnetic ring is disposed at the inner side of the metal housing. The blades are disposed around the outer periphery of the hub. The blades are projected along an extension direction toward the shaft to define projection areas thereof, and the projection area of a top and a bottom of any one of the blades is partially overlapped with other two adjacent blades. A distance between an outer edge of each blade and a rotational axis of the fan decreases proximate the top of the blade and then increases towards the bottom of the blade.

Abstract: The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

Abstract: A centrifugal fan is provided and includes an impeller, a motor, a first case and a second case. The motor is connected with the impeller to drive the impeller to rotate. The first case and the second case are assembled to form an accommodation space for accommodating the impeller and the motor. The first case includes a first side, a first guiding wall, a flow inlet and a flow outlet. The flow inlet is disposed on the first side, the first guiding wall is connected with the first side, and the flow outlet and the flow inlet are located at a same side of the centrifugal fan. The second case includes a second side and a second guiding wall connected with the second side. The first guiding wall and the second guiding wall are assembled to form a flow guiding channel, which has cross-sectional areas with different sizes.

Abstract: A fan includes a frame and an impeller including a hub, a plurality of first blades, a first ring-shaped structure, and a plurality of second blades. The first blades are disposed around the hub. The hub and the first blades are surrounded by the first ring-shaped structure connected with the ends of the first blades, and a central area is structured therebetween. The second blades are connected with an outer rim of the first ring-shaped structure. The frame includes a base, an axle tube portion disposed on the base, and a receiving portion. The impeller is disposed on the axle tube portion. The receiving portion includes plural third blades disposed around the base corresponding to the central area. The first and third blades are matched to each other to be assembled for transforming a tangent velocity into a static pressure to increase the pressure generated by the central area.
