摘要

Heat exchanger for a motor vehicle comprises sealing caps (13) for sealing lateral openings in collecting tanks (6). The sealing caps have fixing elements (40) for fixing the walls (7, 8) of the collecting tanks during insertion into the lateral openings. Assembly aids (30) are arranged on the connecting edges (5) of the tube bases (3) and/or on the ends (16) of the side parts (9, 10) to facilitate assembly of the collecting tanks with the already inserted sealing caps on the tube bases. Preferred Features: Each sealing cap has at least one step (20) that corresponds with at least one protrusion (21) in the longitudinal walls of the collecting tanks.
