Abstract

A multi-chamber tube for a heat exchanger arrangement of a motor vehicle has at least two chamber sections which extend parallel to each other and side-by-side. Different liquid or gaseous heat transfer media are used in the chamber sections which have widths significantly greater than their heights. At least one chamber section has a greater height than at least one other chamber section. The multi-chamber tube is used in a coolant radiator and charge air cooler combination.
