Definitions

  • the invention has the object of providing the generic method in such a way that vanes of different diameters can be produced inexpensively.
  • the ratio of the axial height of at least one flow element, preferably all flow elements, to the axial thickness of the fan blade in the region of the flow element in the region of the leading edge and / or the trailing edge decreases from.
  • the height of the flow element can decrease to 0 in the area between the front and rear edge of the fan blade.
  • the fan blades 3 are distributed unevenly over the circumference of the hub 1.
  • the impeller can also be designed in this way be that the fan blades 3 are arranged distributed uniformly over the circumference of the hub 1.
  • the fan blades 3 each have a leading edge 2 in the direction of rotation 2 and a trailing edge 7 in the direction of rotation 2.
  • the leading edge 6 is sickle-shaped, as viewed in the axial direction of the impeller, i. she has a concave course.
  • the leading edge 6 extends from the hub 1 to the outer edge 8, which extends in the circumferential direction of the impeller.
  • This outer edge 8 has a radial distance from the shell inner side of the fan housing. This distance is set so that the leakage flow is minimized and only a small noise occurs when the air flows from the pressure side 4 through the flow gap formed by the distance to the suction side 5.
  • each fan blade 3 is provided with a transversely projecting flow element 12, which advantageously extends over the entire length of the outer edge 8 between the front edge 6 and the trailing edge 7.
  • the flow elements 12 extend to the suction side 5 of the fan blade 3.
