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.

Exhaust heat exchanger

A heat exchanger assembly and method of making same are disclosed. A plurality of thin walled aluminum tubes are connected to a tube bottom. The tubes are first inserted into the tube support openings in the tube bottom with tube ends flush with a collecting space side of the tube bottom. The tube ends are then welded by a laser beam guided around the circumference of the respective tube ends.
