Definitions

  • Fig. 1 shows a three-dimensional view of a fan.
  • the outer edge region eg, 7 in FIG 4 and 5
  • a plane normal to the rotation axi an angle ⁇ , which is smaller than 35 °, and for example less than 25 °.
  • the angle ⁇ is 12 °.
  • the impeller shown is formed from a flat bottom disk 1, a blade ring consisting of a plurality of stator blades 2 and a cover disk 3.
  • Bottom and cover plate 1, 3 are arranged concentrically with respect to the axis of rotation 4 at a distance B and are connected to each other via the blade ring.
  • the cover plate 3 has an inlet opening 5 with the diameter DE, through which a flow medium is sucked during operation.
  • the fan In operation, the fan is in the drive direction R ( Fig. 3 ), and the vanes promote the flow fluid inside the fan wheel to the outside, where it exits substantially radially at the impeller outer diameter DSa. Due to the negative pressure caused in the inside of the rotor fluid is sucked from the outside through the inlet opening 5.
  • the flow direction thus extends coaxially through the inlet opening 5 in the interior of the impeller and is guided radially outwards, wherein the flow cross section is constantly expanding.
  • the flow initially leaves the diameter of the blades DSa the interspaces 15 in a diffusion space 16, the annular between the outer edges 12 of the vanes 2, the outer edge regions 7, 14 of the cover or the bottom plate 3, 1, and the outer diameter DN of the corresponding outer edges 8 is defined.
