<p>[PROBLEMS] To provide a tank structure of a heat exchanger capable of preventing a tank from being deformed by a thermal shock caused when each tube of the heat exchanger is thermally expanded or contracted in the longitudinal direction. [MEANS FOR SOLVING THE PROBLEMS] In the tank structure of the heat exchanger (1) wherein the ends of tubes (8) are inserted into and fixed to the tube plates (5, 6) of aluminum tanks (3, 4), a bead (12a) extending in the direction orthogonal to the longitudinal direction of the tube (8) is provided on the wall parts (11a, 11b) of the tanks (3, 4) at a position nearer to the tube (8) side than the half position of the height H1 of the wall parts.</p> |
