Abstract
Abstract 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
170 words
An apparatus for cooling a vehicle engine and for air conditioning the vehicle, which comprises: a planar liquid-coolant radiator mounted in the vehicle and operatively connected with the vehicle engine; a planar condenser with the air conditioning unit of the vehicle, said radiator and said condenser being in substantially parallel, spaced apart relation; a fan blade; mounting means for mounting said fan blade between said radiator and said condenser and rotatable in a plane substantially parallel with said radiator and said condenser, said mounting means further being for mounting said fan blade such that rotation of said fan blade in a first direction draws air directly from and through one of said radiator and said condensor and pushes air directly to and through the other of said radiator and said condensor; and rotation means for rotating said fan blade in the first direction to draw air directly from and through one of said radiator and condensor and to push air directly through the other of said radiator and said condenser.
Claim 2
Independent Claim
170 words
An apparatus for cooling a vehicle engine and for air conditioning the vehicle, which comprises: a planar liquid-coolant radiator mounted in the vehicle and operatively connected with the vehicle engine; a planar condenser with the air conditioning unit of the vehicle, said radiator and said condenser being in substantially parallel, spaced apart relation; a fan blade; mounting means for mounting said fan blade between said radiator and said condenser and rotatable in a plane substantially parallel with said radiator and said condenser, said mounting means further being for mounting said fan blade such that rotation of said fan blade in a first direction draws air directly from and through one of said radiator and said condensor and pushes air directly to and through the other of said radiator and said condensor; and rotation means for rotating said fan blade in the first direction to draw air directly from and through one of said radiator and condensor and to push air directly through the other of said radiator and said condenser.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 in which said radiator and said condenser are spaced apart a distance of at most about twice the thickness of said radiator.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 and which includes a shroud surrounding said fan blade.
Claim 5
Dependent Claim
24 words
The apparatus of claim 3 in which said shroud is supported by and integral with said fan blade and rotate with said fan blade.
Claim 6
Dependent Claim
14 words
The apparatus of claim 1 in which said rotation means comprises an electric motor.
Claim 7
Dependent Claim
33 words
The apparatus of claim 5 in which said fan blade includes an interior hub and the electric motor is a pancake motor mounted within the interior hub and integral with said fan blade.
Claim 8
Dependent Claim
26 words
The apparatus of claim 1 in which said fan blade has an axial depth greater than about one-half the distance between said radiator and said condenser.
Claim 9
Dependent Claim
27 words
The apparatus of claim 7 in which the axial depth of said fan blade is greater than about three-fourths the distance between said radiator and said condenser.
Claim 10
Dependent Claim
14 words
The apparatus of claim 7 in which said rotation means comprises an electric motor.
Claim 11
Dependent Claim
18 words
The apparatus of claim 9 in which the electric motor is substantially contained interiorly of said fan blade.
Claim 12
Dependent Claim
33 words
The apparatus of claim 10 in which said fan blade includes an interior hub and the electric motor is a pancake motor mounted within the interior hub and integral with said fan blade.
Claim 13
Dependent Claim
24 words
The apparatus of claim 11 in which said mounting means is for mounting the pancake motor to one of said radiator and said condenser.
Claim 14
Dependent Claim
14 words
The apparatus of claim 12 and which includes a shroud surrounding said fan blade.
Claim 15
Dependent Claim
24 words
The apparatus of claim 13 in which said shroud is supported by and integral with said fan blade and rotates with said fan blade.
