Abstract

PURPOSE: To reduce the entire deformation of a fan having specific vane ratio area, by guiding a ring-shaped reinforcing rib into a vane fixing drum while distributing the tensile stress applied at the root of vane entirely to the bass section.
CONSTITUTION: In a direct-couple radiator cooling fan where the rotation of fan will increase with the rotation of engine and equipped with a fan having vane ratio area of 0.14W0.20 for cooling a car engine, a ring type reinforcing rib 6 is guided into a drum 3 and the boss section 2 is constructed of another rib 7 which connects said rib 6 with a drum 3. Consequently unique tensile stress produced by large vanes can be distributed to the drum 3, ring type reinforcing rib 6 and the coupling rib 7 thereby the deformation of the vane height can be reduced even during high temperature high speed rotation.
