TURBO FAN

PURPOSE: A turbo fan is provided to keep enough blast performance without enlarging an outer diameter of the fan and to reduce noise. CONSTITUTION: A turbo fan comprises a hub(50); multiple blades(70); and a shroud(60). The blades are formed to have negative camber angles to rotating direction of th...

Zusammenfassung:	PURPOSE: A turbo fan is provided to keep enough blast performance without enlarging an outer diameter of the fan and to reduce noise. CONSTITUTION: A turbo fan comprises a hub(50); multiple blades(70); and a shroud(60). The blades are formed to have negative camber angles to rotating direction of the fan. Ratio(d1/d2) of an inner diameter(d1) and an outer diameter(d2) is 0.75-8.85 where the inner diameter connects inner ends of the blades and the outer diameter connects outer ends of the blades. An intake diameter(d0) formed by an inner circumferential surface of the shroud is formed larger than the inner diameter of the blades. Ratio of the intake diameter and the inner diameter of the blades is 0.88-0.95.
