Abstract

La présente invention concerne un échangeur thermique unitaire jumelé assemblé sans utilisation d'ailettes communes. Les ailettes dont les configurations conviennent particulièrement aux différents types d'échangeurs thermiques, sont soudées dans la masse par brasure sans leur réserver d'intervalles. Les hauteurs des tubes et analogues sont identiques pour les différents modèles d'échangeurs thermiques. En l'occurrence, deux échangeurs thermiques dont les principes de fonctionnement sont différents sont montés, l'un en entrée et l'autre en sortie du flux d'air. L'un et l'autre échangeurs thermiques sont formés en prenant une tôle latérale équipant l'un des échangeurs thermiques et en la réunissant par brasure à un réservoir équipant l'autre échangeur thermique.
