Abstract

ROTOR GENERATORA SA ZATVORENIM AKSIJALNIM KANALOM ZA RADIJALNO VENTILISANJE. Pronalazak se odnosi na aksijalni ventilacioni kanal 30 za instaliranje u žljebu za namotaj rotora generatora, pri čemu kanal 30 ima oblik izdužene zatvorene cevi poligonalnog preseka, koja obuhvata uzdužni prolaz 32 i pri čemu je cev tako formirana da ima zatvoreni donji zid i suprotni, bitno zatvoren, gornji zid sa više radijalnih ventilacionih proreza razmaknuto postavljenih duž uzdužnog prolaza 32, dok je kanal konfigurisan tako da bude instaliran u žljebu za namotaj rotora sa prolazom 32 koji se pruža paralelno sa osovinom rotora, a donji zid je okrenut prema osovini rotora, a gornji zid postavljen dalje od osovine rotora.
