Abstract

Echangeur thermique à tubes parallèles à ailettes. A partir du plan de chaque ailette 2, dans la région de celle-ci avoisinant la paroi extérieure du tube 1, est formé de chaque côté du tube, par rapport à la direction d'écoulement S du fluide extérieur, un canal de guidage 3a, 3b de section semi-circulaire, destiné à guider l'écoulement de fluide pour l'amener dans la région périphérique du tube, dans l'ombre portée par celui-ci par rapport à l'écoulement, tous ces canaux de guidage de toutes les ailettes étant formés dans le même sens à partir des plans des ailettes. Applications courantes.
