Abstract

L'invention concerne un échangeur de chaleur (1) pour assurer le transfert indirect de chaleur entre un premier fluide (F1) et un deuxième fluide (F2), qui comprend : une enveloppe (2), laquelle entoure un espace (3) pour recevoir le premier fluide (F1) et au moins un échangeur de chaleur à plaques (4) pour assurer le transfert indirect de chaleur entre les deux fluides (F1, F2), ledit au moins un échangeur de chaleur à plaques (4) étant disposé dans l'espace (3) d'enveloppe de manière à pouvoir être entouré par une phase liquide (L1) du premier fluide (F1), et pour introduire le premier fluide (F1) dans l'espace de l'enveloppe, un dispositif de distribution (6) et/ou un canal de distribution (6) étant disposé(s) dans l'espace (3) d'enveloppe, au-dessus de l'échangeur de chaleur à plaques (4), le dispositif de distribution (6) et/ou le canal de distribution (6) présentant au moins une ouverture de sortie (6b) dirigée vers le bas, apr laquelle la phase liquide (L1) du premier fluide (F1) peut passer pour sortir du dispositif de distribution (6) et/ou du canal de distribution (6) dans l'espace (3) d'enveloppe. Selon l'invention, l'échangeur de chaleur (1) présente un dispositif de guidage (10) disposé en-dessous du dispositif de distribution (6) ou en-dessous du canal de distribution (6), qui est conçu pour guider la phase liquide (L1) du premier milieu (F1) sortant par la au moins une ouverture de sortie (6b).
