Abstract

A heat exchange arrangement for a vehicle has at least two heat exchangers exposed to the action of ambient air. One of the heat exchanger is coolant cooler and the other one is a charge-air coolant. Each of these coolers has tubes through which liquid or gas flows and heat dissipating ribs connected to the tubes. The coolant cooler is positioned upstream of the charge-air cooler in the air-flow direction. The charge-air cooler has an overlapping region in which the coolant cooler and the charge-air cooler overlap one another and a non-overlapping region in which the coolant cooler projects substantially perpendicularly to the cooling air flow direction. The non-overlapping region is formed at least in the charge-air outlet region and is cooled directly by ambient cooling air. The overlapping region is cooled by the ambient cooling air that has passed through the coolant cooler, which is positioned immediately upstream of the overlapping region of the charge-air cooler.
