Abstract

A heat exchanger includes a primary chamber for a primary medium and a secondary chamber for a secondary medium. A gas-tight heat-conducting wall separates the chambers from one another. An outer jacket sheet is disposed at a distance from the wall and defines the secondary chamber along with the wall. A profiled sheet is disposed between the wall and the outer jacket sheet and subdivides the secondary chamber into an inner partial chamber and an outer partial chamber.
