Abstract

A találmány axiális ventilátor (30), amelynek központi agyat (33),valamint legalább három lapátot (34) tartalmazó lapátkereke van.Minden lapátnak (34) lábrésze (35) és fejrésze (36) van. A lapátokat(34) első él (37) és második él (38) határolja, és aerodinamikusprofil-keresztmetszetekkel rendelkeznek, amelyeknek lapátszögefokozatosan és egyenletesen csökken a lapát (34) lábrészétől (35) afejrésze (36) irányábán. A lapátszöget a forgási sík és a lapátkeresztmetszetprofiljának belépő élét és hátsó élét összekötő egyenesvonal által bezárt szög határozza meg. A lapátok (34) egymástól eltérőszögtávolságban helyezkednek el. Lényege, hogy az eltérőszögtávolságok százalékos értéke 1,5% és 8,5% között változik azegyenlő szögtávolságú lapátelrendezéshez képest, ugyanazon lapátszámúventilátorok esetében, vagyis ez a százalékos érték 1,5% < q%<8,5%,ahol Ezáltal a ventilátor (30) természetes módon kiegyensúlyozott, asíkba benyúló konvex éle parabola-alakú szegmensként, a síkba benyúlókonkáv éle viszont másodfokú görbeként van kialakítva.
