Abstract

L'invention concerne des têtes multiples pour un échangeur de chaleur. Au moins deux tuyaux sont disposés de manière parallèle tandis qu'un fluide frigorigène peut se déplacer entre les tuyaux respectifs à travers des trous de communication dans des surfaces latérales étroitement ajustées ensemble. Une pluralité de trous de couplage pour connecter un tube irradiant de la chaleur est disposée sur une surface de la partie supérieure ou la partie inférieure de chaque tuyau, et un trou de couplage de déflecteur pour l'insertion en couplage d'un déflecteur est disposé sur l'autre surface. De manière plus spécifique, chacun des tuyaux possède des fentes à chacune de ses extrémités de façon à aligner les tuyaux les uns aux autres quand les trous de communication sont dans un état aligné, et l'invention comporte des pièces de finition qui sont formées de manière solidaire de façon à s'insérer dans les fentes alignées et ainsi fixer les surfaces latérales de chaque tuyau pour qu'ils s'adaptent étroitement tout en effectuant la finition des extrémités de chaque tuyau, constituant ainsi des têtes multiples pour un échangeur de chaleur selon l'invention. Au moins deux tuyaux peuvent être simplement brasés en alignant précisément les trous de communication à l'aide de la pièce de finition.
