Abstract
The utility model is suitable fore the technical field of air conditioners and provides a wind wheel vane, a tubular wind wheel and an air conditioner. The cross section of the wind wheel vane is in a wing shape. The front edge of the wing shape is composed by connecting a plurality of curves in sequence. The wing-shaped front edge comprises a first curve section and a second curve section connected with the first curve section. The radius of curvature of the first curve section is shorter than that of the second curve section. According to the wind wheel vane, the tubular wind wheel and the air conditioner, the cross section of the wind wheel vane is designed to be a wing shape, so that contact points, with outer mediums, of the front edge of the wind wheel vane is multiple in number and contact area is large. When the wind wheel vane is in working or in a transportation process or drops down, stress on partial portions of the wind wheel vane is small, the wind wheel vane can not be damaged easily and reliability is high.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model embodiment is made as aerofoil profile with the wind wheel blade cross section, and the point of contact of its leading edge and outer medium is many like this, and area is large.This wind wheel blade is in work, in transportation process or when self falling, and its local suffered stress is little, cracky not, and reliability is high.
Below in conjunction with specific embodiment, realization of the present utility model is described in detail.
As shown in Fig. 1～3, the wind wheel blade cross section that the utility model embodiment provides is aerofoil profile, and the point of contact of its leading edge and outer medium is many like this, and area is large.This wind wheel blade 1 is in work, in transportation process or when self falling, and its local suffered stress is little, cracky not, and reliability is high.
Above-mentioned aerofoil profile leading edge sequentially is formed by connecting by many curves, so makes whole aerofoil profile leading edge more smoothly, during with outer medium contact, seems soft.Particularly, described aerofoil profile leading edge comprises the first curved section a1 and the second curved section a2 that is connected with described the first curved section a1, and the radius of curvature of described the first curved section a1 is short than the second curved section a2's.Mainly by curved surface and the outer medium contact at the second curved section a2 place, its surface of contact is comparatively mild herein, and suffered stress is less, and reliability is higher.Preferably, described the first curved section a1 and the second curved section a2 all intercept from circular arc.
Aerofoil profile thickness described in the utility model embodiment is positioned in the middle part of its center line.Described aerofoil profile front-end A is thick than its rear end B, has so improved the intensity of whole wind wheel blade 1, suppresses in transportation, work or the breakage of wind wheel blade 1 when falling.As preferably, described aerofoil profile thickness thickness is t
max, front and rear edges thickness is respectively t
1, t
2, 0.52t wherein
max≤ t
1≤ 0.57t
max, 0.5t
max≤ t
2≤ 0.52t
