Definitions
- An air conditioner adjusts temperature and humidity of the air, and generally comprises an air-cooler, an air-heater, a humidifier, a fan and an air-filter.
- the present invention addresses the problems discussed above and aims to provide a fan's impeller having less noise and greater static pressure.
- the impeller of the present invention is less noisy by 2 dB than the conventional impeller. Further, the impeller of the present invention remains less noisy up to point Q2 where 68% of open-air volume is blown. Regarding the static pressure, the impeller of the present invention gains 32% increase compared with the conventional impeller at point Q3 where 60% of open-air volume is blown.
- Passage centerline B-B is drawn between the midpoints of the leading and trailing edges of blade 12 on a revolution locus.
- the cross sectional view of blade 12 in the radial direction shows a valley in the upper half and shows a peak in the lower half, with regard to windward.
- the upper half is defined as a portion between around the centerline B-B and tip 14, and the lower half is defined as a portion between around the centerline B-B and hub 13.

Claims (5)
- Roue d'un ventilateur, ladite roue comprenant un moyeu (3) monté avec une pluralité d'ailettes (2), et agencée pour faire tourner les ailettes (2), en soufflant ainsi de l'air :dans laquelle une vue en coupe transversale de l'ailette (2) dans une direction radiale représente un pic dans une partie entre une partie centrale de l'ailette et le moyeu (3) par rapport au côté au vent,ladite vue en coupe transversale de l'ailette (2) représente un creux dans une partie entre la partie centrale et l'extrémité (8), etun lieu géométrique de rotation d'un bord d'attaque (6) de l'ailette (2) représente un creux dans une partie entre l'extrémité (8) et la partie centrale de l'ailette (2), et représente un creux dans une partie entre la partie centrale et le moyeu (3), par rapport au côté au vent.
- Roue d'un ventilateur selon la revendication 1, dans laquelle l'épaisseur de l'ailette (2) est constante.
- Roue d'un ventilateur selon la revendication 1, dans laquelle une vue en coupe transversale de l'ailette (12) prise sur un centre de passage allant du bord d'attaque (6) à un bord de fuite (7) est formée pour avoir un rapport d'une épaisseur maximum au niveau du centre de passage sur une distance entre le bord d'attaque (6) et le bord de fuite (7) allant de 5 % à 12 %, incluant les deux valeurs.
- Roue d'un ventilateur selon la revendication 1, dans laquelle la vue en coupe transversale de l'ailette (12) prise sur un axe central de passage reliant le bord d'attaque (6) et le bord de fuite (7) de l'ailette (12) est formée pour être de 5 % ≤ t/c ≤ 12 %, où : t = l'épaisseur maximum de l'ailette (12) et c = l'écartement en profondeur de l'ailette entre les points centraux des bords d'attaque et de fuite.
