Abstract

La présente invention concerne un échangeur de chaleur (1) permettant un échange de chaleur indirect entre un premier milieu (F1) et un second milieu (F2), et comportant une enveloppe (2) comportant un espace (3) servant à recevoir le premier milieu (F1), un bloc d'échange de chaleur (4) situé dans l'espace d'enveloppe (3), qui est entouré par le premier milieu (F1) lors d'un fonctionnement conforme. Le bloc d'échange de chaleur (4) est conçu de manière à refroidir le second milieu (F2) par rapport au premier milieu (F1), de telle sorte qu'une phase gazeuse (G1) du premier milieu se forme dans l'espace d'enveloppe (3). Selon l'invention, un canal collecteur (5) situé dans l'espace d'enveloppe (3) sert à retirer, de l'espace d'enveloppe (3), la phase gazeuse (G1) du premier milieu.
