Title (EN) A FLAT TUBE FOR A HEAT EXCHANGER AND A HEAT EXCHANGER
(FR) TUBE PLAT DESTINÉ À UN ÉCHANGEUR DE CHALEUR ET ÉCHANGEUR DE CHALEUR
Abstract:
(EN) A flat tube for a heat exchanger, with two open ends defining its longitudinal direction, comprising a first wall and a second wall which are flat and parallel to each other, thereby delimiting the inner space of the tube, and further comprising an inner fin located between the first and the second walls, wherein one of the lateral sides of the first wall comprises a main fold running along the longitudinal direction, wherein arms of the main fold form a slit facing the inner space of the tube, and the lateral side of the second wall is bent to cover the main fold.
(FR) La présente invention porte sur un tube plat destiné à un échangeur de chaleur, ayant deux extrémités ouvertes délimitant sa direction longitudinale, qui comprend une première paroi et une seconde paroi qui sont plates et parallèles l'une à l'autre, délimitant ainsi l'espace interne du tube, et comprenant en outre une ailette interne située entre les première et seconde parois, l'un des côtés latéraux de la première paroi comprenant un pli principal s'étendant le long de la direction longitudinale, les bras du pli principal formant une fente faisant face à l'espace intérieur du tube, et le côté latéral de la seconde paroi étant plié pour recouvrir le pli principal.
