Abstract:
A cooler fan assembly for an air compressor comprising:a shroud, said shroud having an air inlet portal and an air discharge portal;a means to produce an air flow, said means to produce an air flow disposed within said shroud;an air passageway defined by said shroud, said air passageway guiding said air flow in a path having a direction into said inlet portal and out of said discharge portal;a compressed-air heat exchanger at a first end of said shroud, said compressed-air heat exchanger in the path of said air flow;a coolant heat exchanger at a second end of said shroud, said coolant heat exchanger in the path of said air flow;and wherein said coolant heat exchanger has a coolant exchanger inlet and a coolant exchanger outlet;said compressed air heat exchanger has a compressed air exchanger inlet and a compressed air exchanger outlet, said compressed air exchanger inlet is fluidly coupled to a separator;said separator provides means to separate coolant from compressed air, both discharged into said separator from an air end;said compressed air exchanger inlet defines a portion of a first pathway which receives said separated compressed air from said separator, said coolant exchanger inlet defines a portion of a second pathway which receives said separated coolant from said separator; said first pathway receives the compressed air at a location from the separator different from where the second pathway receives the separated coolant.
