Claims

[Claims for Utility Model Registration] (1) A tank body 1 with one end open and the ends of a large number of tubes 2 pass through and the penetrating parts are fixed by brazing, and the peripheral edge is attached to the opening edge of the main body 1. A brazed structure of a radiator tank including a tube plate 3 that is liquid-tightly brazed and joined,
The opening end of the main body 1 is formed in a stepped shape protruding outward, and an annular groove 4 having a V-shaped cross section is formed on the periphery of the tube plate 3. A plurality of seat parts 5 are formed on the inner surface of the side wall on the tube side and project slightly independently from each other, and the stepped rising part 6 of the main body 1 is seated on the seat parts 5. A brazed structure for a radiator tank, characterized in that the groove 4 and the opening end of the main body 1 are fixed by brazing with most of the opening edges separated from both inner walls of the groove 4. (2) The angle θ between the opening edge of the main body 1 and the outer side wall of the groove portion 4 is 10° to 20°, and the gap between the opening edge and the inner surface of the side wall is 0.05 mm to 20°.
The structure according to claim 1 of the utility model registration claim in which the diameter is 0.2 mm.
