An apparatus for cooling a vehicle engine and for air conditioning the vehicle is disclosed herein which includes a planar, liquid-coolant radiator parallel with and spaced apart from a planar condenser. A fan blade is mounted between and rotatable in a plane parallel with the radiator and the condenser, and an electric, pancake motor is mounted in the interior of and integral with the fan blade to rotate the fan blade to move air through the radiator and condenser.

Apparatus for engine cooling and vehicle air conditioning

A sheet metal construction for a fan spider. The spider arms each carry an integral rib running centrally along the arm and each rib is flat on its upper surface to mount a fan blade. The novelty of the invention resides in canting forwardly the spider arms. Such canting reduces certain stresses in the fan, thereby reducing cost of manufacture.

Fan spider with rake angle

A flexible fan blade construction of the type wherein a decamber limiter is carried by each spider arm and bears against one side of its associated fan blade to thereby limit flexing (decamber) thereof. According to this invention, the decamber limiter terminates short of the heel of each fan blade. High stress concentrations due to contact between the heel edge of each fan blade and its associated decamber limiter are avoided by this novel construction.

Flexible bladed fan construction

A sheet metal fan blade of improved performance and efficiency has a varying camber angle and chord angle along radial positions of the blade, such that the angle of attack along at least 70% of the length of the blade is not less than 2.degree. or more than 10.degree.. The fan blade construction exhibits utility in an automotive radiator cooling system.

Sheet metal fan

A fan blade mounting employing two integral workpieces formed of sheet metal, each having a central hub portion and radially extending arms, the sheet metal arms of each are centrally bulged or ribbed in the region where they join the hub, the ribs facing in opposite directions to form a cavity in each two-part arm. The central hub portion of each workpiece is depressed from the plane of its arms, the hub portions being nested. Each spider arm is thus stiffened by the compressive loading within one rib when a transverse force is applied on the opposite arm.
