Zusammenfassung: | To provide a centrifugal fan capable of suppressing the generation of noise, and an electronic apparatus provided with the same.SOLUTION: A centrifugal fan includes: a fan having a motor that rotates around a central axis, and a plurality of blades provided on an outer periphery of the motor; and a casing which accommodates the fan, and has an intake port provided in the axial direction of the central axis, and an exhaust port provided in a direction orthogonal to the central axis. An end surface of each of the blades that faces the intake port is provided with a recess-shaped portion that inclines to be recessed toward the motor, and the blades include a plurality of blade groups having different start point positions at which the recess-shaped portions start to incline in a direction from the tips of the blades toward the motor.SELECTED DRAWING: Figure 4
【課題】ノイズの発生を抑制することができる遠心ファン及びこれを備える電子機器を提供する。【解決手段】遠心ファンは、中心軸周りに回転するモータ部と、該モータ部の外周に設けられた複数のブレードとを有するファンと、前記ファンを収容すると共に、前記中心軸の軸方向に吸気口が設けられ、前記中心軸と直交する方向に排気口が設けられたケーシングと、を備え、前記複数のブレードの前記吸気口に対向する端面には、前記モータ部に向かって切り欠かれるように傾斜した切欠形状部がそれぞれ設けられ、前記複数のブレードは、該ブレードの先端から前記モータ部に向かう方向で、前記切欠形状部が傾斜を開始する始点の位置が異なる複数のブレード群を含む。【選択図】図4 |
