CENTRIFUGAL FAN

摘要

A centrifugal fan having improved efficiency and noise reduction includes a hub (110) configured to have a central part combined with a rotary shaft, a shroud (130) spaced apart from the hub, and a plurality of blades (120) provided between the hub and the shroud. The shroud includes outer circumferential parts (131) each connecting the trailing edges (122) of a plurality of respective adjacent blades. Each outer circumferential part is asymmetrically formed based on the center of the outer circumferential part.
