Abstract

L'invention concerne un échangeur (1) de chaleur pour gaz, notamment pour les gaz d'échappement d'un moteur, comprenant une pluralité de conduits parallèles disposés à l'intérieur d'une carcasse (2), dans lesquels circulent les gaz à refroidir par échange thermique avec un fluide de refroidissement ; des moyens de raccord (3) à un conduit de la ligne de recirculation des gaz ; et un conduit de dérivation (6) intégré auxdits moyens de raccord (3) et destiné à faire circuler le fluide de refroidissement jusqu'à une soupape EGR régulant le passage des gaz à travers l'échangeur, caractérisé en ce que lesdits moyens de raccord (3) intégrés audit conduit de dérivation (6) comprennent au moins deux pièces (4,5) fabriquées par estampage.
