Abstract

Un échangeur de chaleur interne pour un circuit d'agent réfrigérant d'un dispositif de climatisation comprend plusieurs tubes d'échangeur de chaleur disposés parallèlement, traversés par l'agent réfrigérant et chacun une tête de distribution (50) entourant les extrémités des tubes d'échangeur de chaleur en formant au moins une chambre de distribution (48, 54) pour l'agent réfrigérant. La tête de distribution (50) présente une paroi périphérique (56) ayant la forme d'un tube profilé ouvert.
