CENTRIFUGAL FAN

摘要

A centrifugal fan includes: a housing; an impeller which is mounted in the housing; a hub which is provided in the impeller and is rotated by a driving force of a motor; and a plurality of blades which radially extend at the hub. Each of the plurality of blades is formed to have a shape curved from a leading edge to a trailing edge in a rotational direction of the impeller in each of the plurality of blades. A farthest point from a plane connecting the leading edge and the trailing edge is defined as a peak portion. The peak portion is placed closer to the leading edge than the trailing edge.

1. A centrifugal fan comprising:
a housing; an impeller mounted inside the housing; a hub provided inside the impeller, the hub being rotated by a driving force of a motor; and a plurality of blades attached to the hub, each of the blades radially extending from the hub and having a leading edge and a trailing edge; wherein each of the plurality of blades has a curved shape from the leading edge to the trailing edge in a rotational direction of the impeller, wherein a peak point of each of the plurality of blades is located closer to the leading edge than the trailing edge, whereby the peak point is a point that is farthest from a plane connecting the leading edge and the trailing edge.
