Heat exchanger e.g. cooler, for cooling charge air of diesel engine of car, has complementary holding units formed on exceeding end of envelope and side wall of fluid inlet and outlet collecting box delimiting groove associated with end

摘要

The exchanger (1) has a heat exchange bundle (3) for exchanging heat between two fluid. An envelope (5) houses the bundle and comprises opposite ends (25, 27) exceeding on two sides of the bundle. A fluid inlet and outlet collecting box (7) comprises a groove (35) for receiving one of the ends of the envelope and an adhesive to assemble the bundle to the box by bonding. Complementary holding units formed by undulations (43) and openings (45) are formed on one of the exceeding ends and a side wall of the box delimiting the reception groove associated with the exceeding end.
