ABSTRACT:
A heat exchanger module, a cooling fan module, a pump/fan module, and an electronics system control module are joined together in assembly to form a total cooling assembly for an automotive vehicle that is powered by an internal combustion engine. The cooling fan module is disposed directly behind the rear face of the radiator, and contains an electric motor-driven fan that draws ambient air across the radiator. At time of installation in a vehicle, the assembly is "dropped into" the vehicle engine compartment and secured in place. An electric motor-driven coolant pump module that pumps engine coolant through the engine and radiator, and an electronics system control module that controls the operation of the fan and pump motors also mount on the cooling fan module. When the vehicle has an air conditioning system, and/or turbo-charged engine, one and/or two additional heat exchangers form part of the heat exchanger module. The cooling fan module may comprise an axial flow fan or a ducted radial flow fan.
