Definitions

  • the invention relates to a blade of a fan wheel, a fan wheel of an axial fan and an axial fan with such a fan wheel.
  • the invention is therefore based on the object to provide a blade construction, a fan wheel for an axial fan and an axial fan, which show improved noise behavior, especially in the upper pressure range at the same time higher efficiency and are less susceptible to Albertanströmungen.
  • This object is achieved by the combination of features according to claims 1-3 and 12.
  • a blade according to claims 1 or 2 is proposed for achieving the object.
  • a fan wheel according to claim 3 is proposed to solve the problem.
  • the radially outer edge portion is defined as a radially outer portion of the respective blade lying portion in the extension of which the projection is formed in the circumferential direction. In the radial direction, the radial outer edge portion is bounded on the outside by the radial outer edge of the respective blade.
  • the blade edge width is defined as the blade width in the circumferential direction at an imaginary edge before, seen in the radial direction, the radial outer edge portion having the projection begins. The blade leading edges extend radially outwardly to the radially outward edge portion before passing into the projection located in the radially outer edge portion.
  • the projection on the individual blades is each nose-shaped as an extension of the radial outer edge portion and projects in the direction of rotation of the blade relative to the respective adjacent, radially outwardly extending, pressure-side blade leading edges in the circumferential direction.
  • the projection is the element which introduces the air engagement and the flow to the blade. The flow along the blade and in particular along the radially outer edge portion is significantly influenced by the projection.
  • the shape of the projection is also advantageous that it is oval in cross-section, more preferably elliptical.
  • the wider section of the oval or elliptical cross section in this case preferably points in the direction of Axialradkarmays, ie along the blade leading edges to the center.
  • the projection tapers in the circumferential direction and is substantially hemispherical in shape, so that the hemisphere head ensures the foremost flow engagement of the respective blade.
  • the projection protrudes in the circumferential direction over a length of 1-20%, in particular 1-10%, more preferably 5-10% of the blade edge width from the adjacent blade leading edge.
  • the blade edge width is measured as described above at the imaginary edge to the radially outer, the projection having region.
  • the length of the projection can then be determined in dependence thereon.
  • the noise generation and efficiency increase are further promoted by the fact that the blades are formed in the respective radial outer edge portion in the front portion adjacent to the blade leading edges with a thickening, that are formed thicker in the axial direction.
  • the thickening is the rear portion of the blades, which adjoins the blade trailing edges and has an unchanged standard thickness.
  • the blade in the front portion has an axial thickness which is greater than an axial thickness in the rear portion adjacent to the blade trailing edges.
  • the transition of the change in thickness from front section to rear section is flowing.
  • the radial outer edge portion of the fan wheel in the radial direction has a length of 5%, more preferably of 2.5% of the radius of the fan wheel. It follows that only the radial outermost region of the blades is geometrically adjusted with the thickening and the projection. The extent of the thickening in the circumferential direction is also defined geometrically.
  • the axially thickened front portion has a width in the circumferential direction, which corresponds to 50%, more preferably up to 70% of the blade edge width.
  • the thickening decreases substantially steadily from the front section towards the rear section.
  • the rear portion itself can be formed just with constant thickness.
  • a winglet bent in the axial direction at a predetermined angle of attack is formed along the radial outer edge of the respective blade, the course of which passes in the circumferential direction into the projection.
  • the winglet acts by a one-piece design with the projection and the thickening together and promotes noise reduction and efficiency.
  • the angle of attack of the winglet with respect to an adjacent plane determined by the blade surface is lower in the front section or in the region of the projection than in the rear section.
  • the invention also includes an axial fan having a stationary wall ring within which a fan wheel described above rotates.
  • the embodiments of the fan wheel according to the invention are particularly effective Positive when used with wall ring, since particularly strong turbulence occur in the gap area between wall ring and fan wheel.
  • FIG. 1 1 shows a plan view of a fan wheel 1 of an axial fan, which has a plurality of blades 2 extending radially outward from a central hub region, with respective pressure side, radially outwardly extending, curved blade leading edges 3 and blade trailing edges 10 and arcuate radial outer edges 4.
  • Each of the blades 2 is identical, so that the description for one blade is identical for all the rest.
  • transition 5 from the radial outer edges 4 to the blade leading edges 3 is formed in each case with a circumferentially extending projection 6 with respect to the adjacent, radially outwardly extending blade leading edges 3.
  • the projection 5 protrudes beyond an imaginary connecting line K of the outermost radial edge points of the geometrically unchanged blade leading edge 3.
  • FIG. 2 shows a detail view X from FIG. 1 ,
  • the radial outer edge section 7 is marked adjacent to the radial outer edge 4 of the blade 2, in the extension thereof in the circumferential direction of the projection 6 is formed.
  • the blade edge width Sb is defined as the blade width in the circumferential direction at an imaginary edge, before seen in the radial direction of the radially outer edge portion 7 having the projection 6 begins.
  • the radial outer edge portion 7 has a length L in the radial direction of 2.5% of the radius of the fan wheel.
  • the blade leading edges 3 extend radially outward to the radially outer edge portion 7 before they pass into the lying in the radially outer edge portion 7 projection 6.
  • the protruding length 6 of the projection 6 protruding beyond the adjacent blade leading edge 3 corresponds approximately to 6.5% of the blade edge width Sb.
  • the projection 6 is designed as a nose-shaped protruding extension of the radial outer edge portion 7 with a substantially hemispherical end. In the circumferential direction are in FIG.
  • FIGS. 3a-3e several sections AA to EE marked in the FIGS. 3a-3e are playing. Furthermore, an in FIG. 2 marked section in the circumferential direction GG in FIG. 3g shown.
  • the cuts of FIGS. 3a-3g let recognize the geometric shape of the blade 2 in the radial outer edge portion 7.
  • the projection 6 has according to FIG. 3a an elliptical cross section, which merges into the shape of the radially and circumferentially adjacent blade 2. In a region adjoining the blade leading edges 3, a front section 8 is determined; in a region adjoining the blade trailing edges 10, a rear section 9 is determined.
  • the areas 8, 9 merge into one another, but the axial thickness D1 in the front section 8 is greater than the axial thickness D2 in the rear section 9 Figures 3c and 3f reproduced with a thickness difference of over 20%.
  • the thickening extends circumferentially over a width Bu of 70% of the blade edge width Sb measured from the front blade edge 3.
  • a thickening in the region of the projection 6 and the adjacent portion As in FIG. 3g also shown in the radial direction is a thickening in the region of the projection 6 and the adjacent portion.
  • a winglet 11 bent in the axial direction at a predetermined angle of attack is integrally formed on the blade 2, as shown for example in FIG FIG. 3f can be seen. The course of the winglet 11 merges into the projection 6 in the front section 8.
  • FIGS. 4 and 5 Figure 12 shows graphs for demonstrating the improved noise and efficiency of the fan wheel 1 over a prior art comparative fan wheel without the features of the present invention. It is in FIG. 4 the comparison of the generated pressure difference, in FIG. 5 the comparison of the difference of the sound power level of the fan wheel according to the invention (line P) over the prior art (line O) shown. It turns out that with the inventive design of the blades 2 according to a FIG. 4 uniform pressure curve is reached, which is in accordance with FIG. 5 reflected in a reduced sound level.
  • FIG. 6 shows an example of the application of the fan wheel 1 from FIG.
