Abstract
A heat exchanger, in particular exhaust-gas cooler, is described herein. The heat exchanger includes tubes of unipartite form or formed from two plates. The tubes form a first and a second fluid duct, and the respective fluid ducts are arranged adjacent to one another. The first fluid duct is designed to be open at at least one of its ends for the inflow and/or outflow of a first fluid. The second fluid ducts are closed at an end side of the tubes by way of an inward or outward step. The step has a greater extent T in the tube longitudinal direction in the corner regions of the tube than between the corner regions. Several non-limiting descriptive embodiments are disclosed herein.
