ABSTRACT:
A radiator fan of an internal combustion engine in a motor vehicle is provided in the form of a one piece injection molded combination of radial fan blades and axial fan blades supported on a conical annulus for increasing air pressure flow across the radiator. The conical annulus has the same axis as that of the hub of the fan. The radial blades connect the interior face of the conical annulus to the hub of the fan. The axial blades are connected to the exterior surface of the conical annulus and extend radially outward. The fan is coupled to the engine through a fluid friction clutch. An air guide ring is positioned upstream of the fan for deflecting axial incoming air flow to help improving efficiency of the fan.
