A high output fan assembly for cooling the radiator of a motor vehicle. The fan assembly comprises a shaft, first and second fans, and a motor. The first fan includes a plurality of first blades, each of which has an inner portion attached to the shaft, while an outer hub is attached to an outer portion of at least one of the first blades. The second fan includes a plurality of second blades, each of which has an inner portion attached to the outer hub. The motor is drivingly connected to the shaft to drive the first and second fans at the same number of revolutions per minute. The fan assembly is situated either for pulling or for pushing air across the radiator and an air conditioning condenser of the motor vehicle.

A combined motor cooler and air aspirator for use in a motor vehicle climate control system comprises a forced air ventilation blower motor having an inlet port for admitting a flow of cooling air and a plurality of housing apertures for allowing the cooling air to exit the motor, a conduit for communicating air from the motor vehicle passenger compartment to the motor inlet port, and means for aspirating air through the conduit and the motor.

Combination motor cooler and air aspirator for climate control system

An interior air temperature sensing system is provided for use with a vehicle interior compartment air temperature regulating system including an ambient air inlet duct, a blower housing connected to an air inlet duct and an air temperature modifier and a blower situated within the blower housing. The blower draws air from the air inlet duct under negative pressure and conveys the air at positive pressure past the air temperature modifier to the interior compartment. The air temperature sensing system includes an air temperature sensor and a venturi valve coupled to the negative pressure area of the blower. The valve includes an inlet port, and outlet port and a venturi section extending therebetween defining a point of minimum flow area, or valve seat. The valve also includes a diverter channel having a first port in communication with the inlet port and a second port in communication with the outlet port and a plug member situated between the inlet port and the outlet port and having a diameter greater than the valve seat. As the blower draws ambient air from the inlet duct, interior compartment air is drawn by the sensor and through the venturi valve and across the valve seat and out the outlet port. If the ambient air pressure exceeds the blower output pressure, the plug member is forced onto the valve seat to divert the oncoming air through the diverter channel creating a secondary venturi and continuing to draw air from the sensor, through the diverter channel to discharge elsewhere within the interior compartment.
