Abstract

L'objectif de cette invention est d'empêcher la corrosion d'une canalisation par une évacuation rapide, vers l'extérieur de cette canalisation, d'un liquide condensé à l'intérieur de celle-ci. A cet effet, l'échangeur de chaleur selon l'invention comporte des parties de retour de fluide coudées (21) d'un côté ou de part et d'autre d'une conduite (20), et présente une forme en U ou en zigzag dans la direction verticale. La partie de canalisation rectiligne supérieure (23) et la partie de canalisation rectiligne inférieure (25), qui sont orientées de manière horizontale à partir de la partie de retour de fluide (21) et disposées du côté supérieur et du côté inférieur de celle-ci, sont inclinées de manière à se séparer progressivement l'une de l'autre en s'éloignant de la partie de retour de fluide (21).
