Abstract

L'invention se rapporte à un échangeur de chaleur de type coaxial pour transfert entre deux fluides. L'échangeur de chaleur comprend un tube externe 1 et un tube interne 2 dont la paroi présente des ondulations 3 s'étendant transversalement par rapport à l'axe longitudinal du tube. Une enceinte cylindrique 10 est placée à l'intérieur du tube interne 2, coaxialement par rapport à celui-ci sur toute la longueur dudit échangeur. Application aux condenseurs de fluide frigorigène pour pompes à chaleur.
