Abstract: A fan includes a fan frame, an impeller, and at least a supporting member. The fan frame includes a bottom plate and a cover plate spaced from the bottom plate. The bottom plate and the cover plate together define a first accommodating space. The cover plate has an air inlet disposed in an axial direction. A side of the fan frame is provided with at least an air outlet. The impeller is disposed in the first accommodating space and includes a hub and a plurality of blades. A cross-sectional area of the hub increases gradually along a direction from the cover plate to the bottom plate. The blades are disposed around the periphery of the hub. The supporting member is disposed between the bottom plate and the cover plate for supporting the cover plate.

Abstract: A mixed flow fan includes a bottom base, an outer cover disposed on the bottom base, a motor disposed on the base, and a hub located between the outer case and the motor. The hub includes a first outer surface and a second outer surface connected to the first outer surface and inclined relative to the first outer surface. The slope of the first outer surface relative to the central axis is greater than the slope of the second outer surface relative to the central axis. The base includes a side surface adjacent to the second outer surface. The slope of the side surface relative to the central axis is equal to the slope of the second outer surface relative to the central axis.

Abstract: A mixed-flow fan includes a base including a bottom channel, an outer cover disposed on the base, a motor disposed on the base, a hub located between the outer case and the motor, and a blade connected to the hub. A main channel is formed between the outer cover and the hub, and is connected to the bottom channel. The main channel extends in the first direction, and the bottom channel extends in the second direction.
