The invention relates to an exhaust gas heat exchanger for motor vehicles, comprising a cluster of exhaust pipes () which are soldered on the front surface thereof to pipe bottoms, and a housing jacket () which is welded to the pipe bottoms (). According to the invention, the pipe bottoms are welded to the housing jacket () by means of peripheral welds ().

Exhaust gas heat exchanger and method for the production thereof

In a heat exchanger used especially as an exhaust heat exchanger, provision is made for tube sheets, the tubes of a tube bundle, and a housing to be shaped from stainless steel sheets. The tube sheets are formed as deep-drawn and stamped parts, each of which has a circumferential wall that projects outward beyond the ends of the tubes in the tube bundle. The walls are welded to the housing, and each of the walls is abutted by a diffuser.
