Abstract
Disclosed herein is a fan and shroud assembly comprising: a fan having a hub rotating on a shaft and a plurality of blades extending outward from the hub; and a shroud surrounding the fan for controlling air blast by rotation of the fan, wherein the shroud comprises: a guide ring part spaced apart at a predetermined interval from the periphery of the fan which connects ends of the blades; and swirl preventing means formed on the guide ring part for preventing swirling airflow along the periphery of the fan connecting the ends of the blades. The fan and shroud assembly can minimize generation of swirling airflow and backflow and provide improved noise-reduction effect.
