Abstract

La présente invention concerne un segment coulé destiné à un échangeur de chaleur sectionnel d'une cellule thermique à condensation et comprenant deux parois coulées, une chambre de combustion pour la génération de gaz de combustion, et un canal d'écoulement d'eau délimité par les deux parois coulées. Le canal d'écoulement d'eau est prévu pour l'écoulement d'eau à chauffer par un gaz de combustion par transfert de chaleur à travers au moins une des deux parois coulées. Le canal d'écoulement d'eau comprend, le long de sa longueur, une première section, une deuxième section et une troisième section. Dans la première section, des parois intermédiaires sont disposées entre les deux parois coulées de telle sorte qu'un canal d'écoulement sinueux est prévu dans la première section. La troisième section entoure la chambre de combustion sur au moins 330°. La deuxième section raccorde la première section à la troisième section. La deuxième section est parallèle à au moins une partie de la troisième section et s'étend le long de ladite partie. La distance moyenne entre les deux parois coulées dans la deuxième section est supérieure à la distance moyenne entre les deux parois coulées dans la troisième section. La distance moyenne entre les deux parois coulées dans la deuxième section est supérieure à la distance moyenne entre les deux parois coulées dans la première section.
