を特徴とする熱交換器のタンク構造。 A heat exchanger tank structure in which the periphery of a relatively thick tube plate 1, in which the ends of a large number of tubes are penetrated and joined, and the opening of a cast tank body 2 with one end open are welded by inert gas shield arc welding. An annular thick-walled portion 3 is integrally formed on the outer circumferential surface of the main body 2 slightly inside the opening end thereof to protrude, and the depth thereof is shallower than the thickness of the tube plate 1 at the inner circumferential edge of the opening. The tube plate 1 has a stepped fitting part 4 formed therein, and a stepped part 5 aligned with the fitting part 4 is formed on the inner peripheral edge.
is fitted into the fitting portion 4 so that the outer circumferential surfaces near the contact portion of both are on the same plane, and when the contact portion of the outer circumferential surface is inert gas shield arc welded, the ejected shielding gas is attached to the thick wall. A shielding gas guide surface 6 is formed on the end surface of the thick portion in a curved or inclined surface shape for guiding the shielding gas in a direction in which it is diffused from the contact portion without being reflected toward the contact portion at the end surface of the thick portion. The tank structure of the heat exchanger.
