Abstract:
In a vehicular cooling system the combination ofan inlet for receipt of ambient air; first and second heat exchangers in proximity to said inlet to receive ambient air therefrom and respectively adapted to receive first and second heat exchange fluids to be cooled by the ambient air; said first and second heat exchangers being in side by side, substantially non superimposed relation to define first and second air flow paths extending in fluid flow parallel through a respective one of said heat exchangers from said inlet to one or more points of discharge; one or more fans for flowing air from said inlet through said first and second flow paths: a shutter in one of said flow paths and movable between a first position relatively restricting air flow through said one flow path and a second position allowing relatively unrestricted air flow through said one flow path and additional positions intermediate said first and second positions; an actuator for moving said shutter between said positions; and a control for said actuator, said control including a fan drive controller for said fan(s) operative to a) control the speed of said fan(s) and b) provide a position control signal for said actuator.
