Abstract

VENTILATEUR HELICOIDE DE DIAMETRE SUPERIEUR A DIX METRES POUR ASSURER LE PASSAGE DE TRES GRANDS DEBITS D'AIR A TRAVERS DES REFRIGERANTS OU DES TOURS DE REFRIGERATION SECHES OU HUMIDES. ON A CHOISI UN TYPE DE VENTILATEUR A GRAND MOYEU POUR POUVOIR PLACER A SA PERIPHERIE UNE COURONNE FORMANT INDUIT, EN FACE D'UN INDUCTEUR EN ARC DE CERCLE FIXE DANS LE CAS D'UN ETAGE UNIQUE OU LUI-MEME MOBILE SI LE VENTILATEUR COMPORTE DEUX ETAGES TOURNANT EN SENS INVERSE L'UN DE L'AUTRE, CE QUI CONDUIT A UN MEILLEUR RENDEMENT DE L'ENSEMBLE, LE MOTEUR LINEAIRE COURBE POURRA ALORS AVOIR UN EXCELLENT RENDEMENT ETANT DONNE L'IMPORTANCE DES VITESSES RELATIVES. DE TELLES MACHINES TROUVENT LEUR APPLICATION DANS L'INDUSTRIE PETROLIERE, L'INDUSTRIE CHIMIQUE, LES CENTRALES DE PRODUCTION D'ENERGIE ETC.
