Abstract:
1. A method for cooling fluids used in an engine of a motor vehicle, comprising: providing a heat exchanger assembly comprising: flowing the engine coolant through the radiator from the upper end to the lower end thereof; flowing the charge air in sequence in through the upper manifold of the upper charge air cooler portion, the tubes of the upper charge air cooler portion, the lower manifold of the upper charge air cooler portion, the conduit extending from the lower manifold of the upper charge air cooler portion and around a side of the radiator intermediate the radiator ends to the upper manifold of the lower charge air cooler portion, the upper manifold of the lower charge air cooler portion, the tubes of the lower charge air cooler portion, the lower manifold of the lower charge air cooler portion, and to an air intake manifold of the engine; and flowing cooling air through the heat exchanger assembly such that the cooling air flows sequentially first through the upper end of the radiator and subsequently through the upper charge air cooler portion, and the cooling air also flows sequentially first through the lower charge air cooler portion and subsequently through the lower end of the radiator, to cool the engine coolant in the radiator and the charge air in the charge air cooler portions.
