Abstract

L'invention porte sur un échangeur de chaleur hybride qui comprend un noyau hybride pourvu d'un premier noyau formé d'un premier élément d'échange de chaleur et d'un second noyau disposé adjacent au premier noyau et formé d'un second élément d'échange de chaleur, une paire de collecteurs disposés sur des côtés opposés du noyau hybride commune aux premier et second noyaux, et une paire de réservoirs commune aux premier et second noyaux. Chaque collecteur est pourvu de première et seconde fentes destinées à recevoir respectivement de premier et second éléments d'échange de chaleur. Chaque réservoir est serti sur le collecteur correspondant et est divisé en une première chambre qui, conjointement avec les premières fentes, facilite la distribution du premier fluide d'échange de chaleur vers le premier noyau correspondant et la collecte du premier fluide d'échange de chaleur depuis ce dernier, et en une seconde chambre qui, conjointement avec le second ensemble de fentes, facilite la distribution du second fluide d'échange de chaleur vers le second noyau correspondant et la collecte du second fluide d'échange de chaleur depuis ce dernier.
