Title (EN) HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR
Abstract:
(EN) A heat exchanger comprises a plurality of flat tubes (1) for heat exchange between a first fluidum flowing inside said tubes (1) and a second fluidum flowing outside of said tubes (1). A pair of hollow headers (3, 4) is connected to the end of the flat tubes (1) an inlet (6) and an outlet (7) being provided in the headers (3, 4) for introducing the first fluidum into the flat tubes and discharging it therefrom. Each header (3, 4) is composed of at least two parallel tubes (16, 17, 18, 19) with substantially circular cross section, two adjacent tubes having integrated wall portions (20, 21, 22), thereby providing a substantially flat header (3, 4).
(FR) L'invention concerne un échangeur de chaleur comprenant une pluralité de tubes plats (1) permettant l'échange de chaleur entre un premier fluide s'écoulant à l'intérieur desdits tubes (1) et un second fluide s'écoulant à l'extérieur desdits tubes (1). Une paire de collecteurs creux (3, 4) est reliée à l'extrémité des tubes plats (1), lesdits collecteurs présentant une entrée (6) et une sortie (7) permettant d'introduire le premier fluide dans les tubes plats et de l'évacuer. Chaque collecteur (3, 4) est formé d'au moins deux tubes parallèles (16, 17, 18, 19) avec une section transversale sensiblement circulaire, deux tubes adjacents présentant des parties (20, 21, 22) de paroi solidaires, ce qui permet d'obtenir un collecteur (3, 4) sensiblement plat.
