Abstract

LE TUBE DE TRANSFERT THERMIQUE COMPORTE UN CERTAIN NOMBRE DE CANNELURES HELICOIDALES PRESENTANT UN ANGLE D'HELICE SPECIFIQUE ET UN RAPPORT ENTRE LA HAUTEUR DE CANNELURE ET LE DIAMETRE DU TUBE DE MANIERE A ETABLIR UN RAPPORT ENTRE LE POUVOIR DE DIFFUSION THERMIQUE ET LE POUVOIR DE DIFFUSION DE LA VITESSE ACQUISE SUPERIEUR A 1. LE TUBE PEUT ETRE FAIT EN PARTANT D'UNE BANDE PLATE DE MATERIAU DE BASE DONT LES FACES OPPOSEES SONT ETIREES, PAR LAMINAGE OU AUTREMENT, POUR FORMER DES CANNELURES LONGITUDINALES DE CONTOUR SPECIFIQUE, APRES QUOI LA BANDE EST ENROULEE EN HELICE AUTOUR D'UN MANDRIN ET LES BORDS EN ABOUT SONT ASSEMBLES DE MANIERE A CE QUE LES PLISSEMENTS DE SURFACE FORMENT DES FACES A CANNELURES HELICOIDALES CONTINUES MULTIPLES, A LA FOIS SUR L'INTERIEUR ET L'EXTERIEUR DU TUBE.
