Abstract: A centrifugal fan includes a centrifugal impeller, a first housing, a second housing, an annular guide ring and a driving device. The centrifugal impeller has a hub and blades connected to and disposed around the hub. The first housing and the second housing cooperatively define a hollow chamber and an air outlet. An air inlet is formed in a central section of the second housing. A first arc structure is located on an inner surface around the air inlet of the second housing. Support brackets respectively extend from an end close to a tongue of the second housing and an end away from the tongue of the second housing. The support brackets are perpendicular to the second housing. The annular guide ring has a second arc structure close to an outermost margin of inner surfaces of the blades. The driving device is used for rotating the centrifugal impeller.

Abstract: A centrifugal fan is provided. The centrifugal fan includes a housing, a driving device, and blades. The housing includes a circular base and at least two struts. Each of the struts physically connects the circular base and the remainder of the housing, and each of the struts includes two peripheral edges. The driving device is placed on the circular base. Each of the blades has an arc shape and the blades are located in the housing. The driving device rotates the blades. The two peripheral edges of each of the struts form orthogonal curves with the blades.

Abstract: A centrifugal fan includes a housing, a driving device, and a fan impeller. The housing has a hollow chamber which has a central axis. The driving device is located at the central axis of the hollow chamber. The fan impeller is disposed in the hollow chamber and includes a hub, several blades, and several fins. The hub is connected with the driving device. The blades are disposed around the hub. Each blade has a windward surface and a leeward surface. Each fin extends from the windward surface of one of the blades, outward by an arc surface from the windward surface starting from a location near the central axis, and further extends to the leeward surface of an adjacent blade.

Abstract: A centrifugal fan includes a spiral housing, a driving mechanism and multiple internally mounted impellers. The driving mechanism and the centrifugal impeller, rotated by the driving mechanism, are installed in the spiral housing. A spiral flow channel is defined between the centrifugal impeller and the spiral housing. When the centrifugal impeller rotates, airflow is sucked axially into the spiral housing through an inlet opening and moves along each blade of the centrifugal impeller into the spiral flow channel. The centrifugal impeller includes a hub and multiple blades. Each blade is secured to the hub at one end and has at least one vertical convex strip or vertical concave strip at an opposite end, wherein the vertical convex strip or vertical concave strip on each of blade disturbs the airflow across thereof and reduces narrow-band noise.
