Abstract:
1. A combined radiator and charge air cooler package comprising: a radiator for cooling engine coolant having opposite front and rear core faces through which ambient air flows, and opposite upper and lower ends adjacent the faces; and a charge air cooler for cooling charge air having upper and lower units, each charge air cooler unit having opposite front and rear core faces through which ambient air flows, and opposite upper and lower ends adjacent the faces; the upper charge air cooler unit being disposed in overlapping relationship and adjacent to the upper end of the radiator with the upper and lower ends of the upper charge air cooler unit being oriented in the same direction as the upper and lower ends of the radiator, wherein one face at the upper end of the radiator is disposed adjacent one face of the upper charge air cooler unit, such that the ambient air flows in series through the upper end of the radiator and the upper charge air cooler unit; and the lower charge air cooler unit being disposed in overlapping relationship and adjacent to the lower end of the radiator with the upper and lower ends of the lower charge air cooler unit being oriented in the same direction as the upper and lower ends of the radiator, wherein the other face at the lower end of the radiator is disposed adjacent one face of the lower charge air cooler unit, such that the ambient air flows in series through the lower charge air cooler unit and the lower end of the radiator, each charge air cooler unit having a different core style from the other, the core style being selected from the group consisting of core depth, type of fins, fin spacing, fin count, tube spacing and tube count; and the charge air cooler units being operatively connected such that the charge air flows therebetween.
