Abstract

L'invention concerne un échangeur de chaleur permettant d'éviter de manière simple et fiable la corrosion des couches métalliques de transfert de chaleur.　La présente invention concerne un échangeur de chaleur pourvu : d'une calandre externe (1) à l'intérieur de laquelle circule un agent de transfert de chaleur ; et d'ailettes internes (2) qui sont logées dans la calandre externe (1) dans un état où une partie des ailettes internes est en contact avec la surface interne de la calandre externe (1). L'échangeur de chaleur de l'invention est configuré de telle sorte que : la calandre externe (1) est constituée d'un matériau stratifié d'extérieur de calandre (L1) dans lequel, sur au moins un côté d'une couche métallique, une couche de résine polymère est stratifiée ; et les ailettes internes (2) sont constituées d'un matériau stratifié d'intérieur de calandre (L2) dans lequel, sur les deux côtés d'une couche métallique de transfert de chaleur (61), des couches de résine adhésive thermofusible (62) sont respectivement stratifiées. Sur un bord latéral (7a) du matériau stratifié d'intérieur de calandre (L2), une section de bord mince (7) est formée, et la section de bord mince (7) comprend : un bord latéral (6a) de la couche de transfert thermique (61) ; des sections stratifiées de bord latéral de couche de transfert thermique (72) qui sont faites d'une résine et qui sont stratifiées sur les deux côtés du bord latéral (6a) ; et une section de couverture de surface d'extrémité de couche de transfert thermique (73) qui est faite d'une résine et qui couvre une surface d'extrémité (6b) de la couche de transfert thermique (61).
