Abstract

L'invention concerne un échangeur de chaleur (1), destiné à la transmission de chaleur indirecte entre un premier fluide (M1) et un deuxième fluide (M2), comprenant : une enveloppe (2) qui possède un espace d'enveloppe (3) destiné à recevoir une phase liquide (F1) du premier fluide (M1), et au moins un bloc de transfert thermique (4) qui possède des premiers passages de transfert thermique destinés à recevoir le premier fluide (M1) ainsi que des deuxièmes passages de transfert thermique destinés à recevoir le deuxième fluide (M2), de manière à pouvoir réaliser une transmission de chaleur indirecte entre les deux fluides (M1, M2). Ledit bloc de transfert thermique (4, 5) est disposé dans l'espace d'enveloppe (3) de telle sorte qu'il peut être entouré par une phase liquide (F1) du premier fluide (M1) qui se trouve dans l'espace d'enveloppe (3). Conformément à l'invention, une pluralité de conduits (10) cylindriques parallèles les uns aux autres, destinés à conduire la phase liquide du premier fluide (M1), sont disposés dans l'espace d'enveloppe (3) latéralement audit bloc de transfert thermique (4).
