BLADE FOR CENTRIFUGAL FAN DEVICE, CENTRIFUGAL FAN DEVICE, AND ELECTRONIC DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a blade for a centrifugal fan device capable of increasing a cooling performance without increasing a rotational speed of a centrifugal fan by efficiently sucking outside air into the centrifugal fan and capable of cooling a wide range by dividing distal ends of blades of the centrifugal fan to divide the airflow directions, and to provide the centrifugal fan device and the electronic device including the same.

SOLUTION: This blade for a centrifugal fan device including a blade 22 having a plurality of blades extending in a radial direction from a hub part as a center and a ring-like flow straightening plate 30 extending outward from the hub part 21 and reinforcing the blades. The blade 22 has a first region integrated in a thickness direction of the blades in a radial direction inner side and a plurality of divided second regions divided in the thickness direction of the blades in a radial direction outer side. A division point of the blade is outside the outer diameter of the flow straightening plate 30 in the radial direction.
