RING FAN AND SHROUD AIR GUIDE SYSTEM |
摘要 |
A ring fan and shroud guide system which includes a rotating fan member with a conical outer ring and a cylindrical shroud member overlapping at least a portion of the outer ring. A plurality of guide vanes are provided in the shroud which minimize the tangential velocity component of the air flow entering the tip-gap region and provide improved air flow through the system. The guide vanes can have a curved configuration. |

1. A ring fan and shroud air guide system comprising:
a fan member having a hub and a plurality of blades extending outwardly from the hub; a ring member attached to the blades, said ring member having a conical axially extending shape; a shroud member positioned around said fan member and ring member, said shroud member having a portion axially overlapping and radially inward of a first portion said ring member and forming a tip gap with a second portion of said ring member; and a plurality of guide vanes positioned in said shroud member, said guide vanes having a configuration to minimize the tangential component of the recirculation air flow through said tip gap. |
