Title:
CENTRIFUGAL FAN, AND AC GENERATOR FOR MOUNTING ON VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/215785
Kind Code:
A1
Abstract:
This centrifugal fan is provided with an annularly formed main plate, a plurality of arm-like plates extending radially outward from the outer periphery of the main plate, and a blade extending from each of the plurality of arm-like plates. At least one of the main plate and each of the arm-like plates is provided with an axially extending opening. Forming the opening through which air is allowed to flow axially can increase the amount of axially flowing air without increasing noise. Consequently, the cooling performance of an AC generator for mounting on a vehicle can be increased.
