Abstract
A heat exchanger, particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid and second and third fluids that have different temperatures includes a block for separately conducting the first and second and third fluids in a heat transferring manner. The block encompasses a number of ducts through which the first fluid can flow, a first chamber of a high-temperature part through which the second fluid can flow and which accommodates the ducts, a second chamber of a low-temperature part through which the third fluid flows and which accommodates the ducts, and a housing in which the first and second chamber as well as the ducts are arranged. The first chamber and the second chamber are separated from one another by a separation area that is mounted in a groove.
