Abstract

L'invention concerne un échangeur de chaleur (36) qui comprend une pluralité de tubes d'échangeur de chaleur conçus pour être parcourus par un liquide de refroidissement et au moins deux boîtiers d'échangeur de chaleur (40, 42) raccordés à l'échangeur de chaleur au niveau d'extrémités opposées. Au moins un des boîtiers d'échangeur de chaleur (42) forme une ouverture de raccordement (52) qui est intégrée dans une interface de raccordement (50) pour la connexion à un élément de raccordement. L'échangeur de chaleur peut être combiné à plusieurs éléments de raccordement fonctionnellement différents pouvant être raccordés alternativement à l'ouverture de raccordement (52) en communication fluidique au niveau de l'interface de raccordement (50). Cette solution permet de configurer l'échangeur de chaleur (36) sous la forme d'un module de base à modifier le moins possible qui peut, en fonction d'une variante à réaliser, être combiné à un parmi plusieurs éléments de raccordement intégrant les différences définissant les variantes.
