Definitions

  • the relationship between the length L1 of the radially inward edge of the guide vane and the length L2 of the guide vane at the level of the concaveness meets the condition: 1,8 ⁇ L1/L2 ⁇ 2,3 and the concaveness level is given by the condition: 0,4 ⁇ H1/H2 ⁇ 0,9 preferably 0,5 ⁇ H1/H2 ⁇ 0,8 where H denotes the height for the concaveness position from the radially inward edge and H2 the total height of the guide vane.
  • Figure 4 illustrates the guide vane of Figure 3 with constant curvature
  • Figure 5 illustrates an alternative embodiment of the guide vane in accordance with the invention, also extended in a plane.
  • the lengths L1 and L2 meet the condition: 1,8 ⁇ L1/L2 ⁇ 2,3.
  • the vane will thus be useful for practically all axial fans used in practice.
