Abstract
An ambient air-to-engine fluid heat exchanger, vehicle having independent ambient air modulators are provided for both the radiator and the charge air cooler in the form of an apertured plate mounted adjacent the face of the heat exchanger and controllably slidable to bring the plate apertures in registry with the ambient air openings of the heat exchanger. For the heat exchanger for engine coolant, the front face of the heat exchanger comprises a second plate having the heat exchanger ambient air openings therein. For the charge air cooler, a second plate is unnecessary because, in an air-to-air heat exchanger, the charge air tubes are about the same width as the ambient air passages and thus the tubes can block the air flow through the modulator apertures when the plate is positioned to do so. The modulator plate is further preferably provided with integral louver portions between the apertures for channelling and streamlining the ambient air flow into the apertures and heat exchanger.
