Abstract

Dans un generateur a courant alternatif ayant un ventilateur de refroidissement (1) monte adjacent a la surface extreme peripherique externe d'une potence frontale (2), il est prevu une pluralite d'events d'admission (22) formes sur la surface peripherique de la partie cylindrique (2a) de la potence frontale (2), une pluralite d'events d'admission (23) formes sur la surface de la potence frontale (2) au voisinage d'un redresseur (6), une pluralite d'events de refoulement (32) formes sur la partie cylindrique (3a) d'une potence arriere (3), et un ventilateur centrifuge (10) monte sur la surface laterale d'une potence arriere (5) d'un rotor. Ainsi, deux chemins de ventilation sont formes: l'un aspire par un event (31) dans la potence arriere (3) par le ventilateur centrifuge (10) et refoule au travers des events (32); l'autre aspire par les events (22, 23) et refoule au travers d'un event (21) dans la potence frontale (2), de sorte que la resistance de ventilation est suffisamment petite pour assurer la quantite necessaire d'air de ventilation.
