Abstract

Titre de l’invention : Échangeur de chaleur pour boucle de fluide réfrigérant L’invention vise un échangeur de chaleur (1) comprenant une surface d’échange de chaleur (2), un collecteur d’entrée de fluide (3) et un collecteur de sortie de fluide (4), une première boîte collectrice (6) et une deuxième boîte collectrice (7), cette surface d’échange de chaleur (2) comprenant un premier ensemble de tubes (5A) et un deuxième ensemble de tubes (5B). Selon l’invention, l’échangeur de chaleur (1) comporte un conduit (8) et un canal (9). L’échangeur de chaleur (2) comprend au moins un premier circuit de fluide réfrigérant constitué du collecteur d’entrée (3), du conduit (8), de la première boîte collectrice (6), des tubes du premier ensemble (5A) et du collecteur de sortie (4), et au moins un deuxième circuit de fluide réfrigérant constitué du collecteur d’entrée (3), des tubes du deuxième ensemble (5B), de la deuxième boîte collectrice (7), du canal (9) et du collecteur de sortie (4). Figure de l’abrégé : Figure 1Title of the invention: Heat exchanger for refrigerant loop The invention relates to a heat exchanger (1) comprising a heat exchange surface (2), a fluid inlet collector (3) and a fluid outlet (4), a first manifold (6) and a second manifold (7), this heat exchange surface (2) comprising a first set of tubes (5A) and a second set of tubes ( 5B). According to the invention, the heat exchanger (1) comprises a conduit (8) and a channel (9). The heat exchanger (2) comprises at least a first refrigerant circuit consisting of the inlet manifold (3), the duct (8), the first manifold (6), the tubes of the first set (5A) and the outlet manifold (4), and at least one second refrigerant circuit consisting of the inlet manifold (3), the tubes of the second set (5B), the second manifold (7), the channel (9 ) and the outlet collector (4).
