摘要： The invention relates to a heat exchanger for motor vehicles, comprising: a core (2) comprising a tube bundle of open ends stacked tubes (3) and comprising a top and a bottom extreme tubes (3a,3b); headers (4,5), each having a shaped flange (4a,5a) with corners (4b,5b) and being connected with open ends of the tubes (3,3a,3b); and side housing parts (6, 7) situated on opposite sides of the core (2) and extending at least partly between the extreme tubes (3a,3b) and between the header (4,5). At least one of the side housing parts (6,7) have at least one protrusion (10) projecting from the side housing part (6,7) in a corner thereof and bent to contact the side surface of the tube bundle; the at least one protrusion (10) has an external surface (10′) opposite to the tube bundle and formed into a shape matching the profile shape of the flange (4a,5a) of the header (4,5) in its corner (4b,5b); wherein the said external surface (10′) of the at least one protrusion (10) abuts the flange (4a,5a) of the said header (4,5) to ensure a liquid-tight connection of the header (4, 5) with the flange (4a, 5a) at the corner (4b,5b) thereof.
