Title
(EN) DUMBBELL SHAPED PLATE FIN
(FR) AILETTE EN FORME D'HALTÈRE
Abstract
(EN) A heat exchanger element for use in a heat exchanger includes an outer wall formed into a tubular shape including a first portion and a second portion. The first portion is arranged parallel to and is spaced apart from the second portion. A plurality of fin structures extends between the first portion and the second portion of the outer wall. Each of the fin structures defines a flow channel configured to provide fluid communication between an outer surface of the first portion of the outer wall and an outer surface of the second portion of the outer wall. An interior of the outer wall is configured to receive a first fluid while an exterior of the outer wall and each of the flow channels defined by the fin structures are configured to receive a second fluid in heat exchange relationship with the first fluid.
(FR) Élément d'échangeur de chaleur destiné à être utilisé dans un échangeur de chaleur comprenant une paroi extérieure de forme tubulaire comprenant une première partie et une seconde partie. La première partie est disposée parallèlement à la seconde partie et est espacée de celle-ci. Une pluralité de structures d'ailette s'étend entre la première partie et la seconde partie de la paroi extérieure. Chacune des structures d'ailette définit un canal d'écoulement configuré pour assurer une communication fluidique entre une surface extérieure de la première partie de la paroi extérieure et une surface extérieure de la seconde partie de la paroi extérieure. Un intérieur de la paroi extérieure est configuré pour recevoir un premier fluide tandis qu'un extérieur de la paroi extérieure et tous les canaux d'écoulement définis par les structures d'ailette sont configurés pour recevoir un second fluide en relation d'échange de chaleur avec le premier fluide.
