Abstract: A fan includes a frame, an impeller and a motor. The impeller includes a hub, a plurality of blades, first air-guiding plates and second air-guiding plates. The hub has a tapered shape. A width of the hub gradually increases along a direction from a top portion of the hub to a bottom portion of the hub. The hub has at least an air vent. The blades are disposed around an outer periphery of the hub. The first air-guiding plates and the second air-guiding plates are disposed around an inner periphery of the hub. The first air-guiding plates are arranged between two of the second air-guiding plates in staggered. The second air-guiding plates are arranged between two of the first air-guiding plates in staggered. The first air-guiding plates and the second air-guiding plates have different thicknesses, heights or shapes.

Abstract: A combination structure of a fan guard and static blades is disclosed. The fan guard includes an annular plate, multiple radial ribs, and multiple circumferential ribs. The annular plate is fixed on a motor base. The radial ribs arranged around the annular plate extend radially. The circumferential ribs are arranged concentrically and spacedly and connected with radial ribs in series. Each of the static blades includes a blade body, an inner and an outer coupling plate. The inner coupling plate and the outer coupling plate are arranged on two ends of the blade body respectively. The blade body is fixed on one side of the fan guard through the inner coupling plate being combined with one end of the radial rib and through the outer coupling plate being combined with another end of the radial rib to make the static blades be combined on the fan guard.

Abstract: A centrifugal fan is disclosed and includes a lower case, an impeller and an upper case. The lower case includes a bottom plate and a sidewall. The impeller is disposed on the bottom plate. The upper case is assembled with the sidewall to form an outlet. The upper case is formed by stamping and includes a first plane, an inlet and a grille. When the impeller is rotated, an airflow flowing from the inlet to the outlet is formed. The grille is protruded outwardly from the first plane, and includes a connecting frame and plural ribs. A spacing height is formed between the connecting frame and the inlet. Each rib has a first end connected to the connecting frame and a second end connected to the first plane. A pair of notches are disposed adjacent to two opposite lateral edges of the second end of the corresponding rib, respectively.

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.
