Definitions

  • the invention relates to a cross-flow fan consisting of a fan roller with blade edges running parallel to the axis of rotation, a guide plate partially encompassing the fan roller, a vortex former and the side parts wholly or partially surrounding the fan roller ends.
  • the cross-flow fan can produce a siren-like sound that clearly stands out from the usual noise.
  • This siren-like sound is known to the experts under the name "SchaufeL frequency peak"; the height of this tone can be: are calculated, where n is the number of revolutions of the fan roller per minute and z is the number of blades of the fan roller.
  • the invention is therefore based on the object of specifying measures which reduce the siren-like sound with a cross-flow fan operated at low to medium counterpressures or completely prevent such that no changes occur in the stable operating behavior and the air performance.
  • the new solution should also be effective for any length of cross-flow fan.
  • this object is achieved in that the vortex generator is provided on the suction side with a sharp-edged interfering body which extends at least over half its length, close to its greatest approximation to the circumference of the ventilation roll.
  • a cross-flow fan consists of the guide plate 1, the side parts 2, the fan roller 3 and the vortex former 4. If the fan roller 3 is rotated in the direction of the arrow 5 by a motor, not shown, then air becomes air sucked in from the space above the vortex former and blown out from the pressure chamber below the vortex former 4 in the direction of the arrow 6.
  • the fan roller should have diameter D.
  • the fan roller 4 which is rotated in the direction of the arrow 5, causes an intake flow in the space C above the vortex image 3.
  • the vortex flow 7 with the vortex center 8 is present in the fan roller 3 and below the vortex former 4 in space A is the flow on the pressure side.
  • the blades on their way from room A to room C cross room B, in which there is a strongly turbulent flow.
  • This strong turbulent flow has its cause in the disturbing body 9 on the vortex generator 4. It has the consequence that the blade does not come abruptly from the pressure into the suction zone, but that the transition takes place gradually.
  • room B can R.Hopfensperger-K.Täschner 11-4
  • the interfering body 9 can be a web which is stamped out of the vortex former 4 and which extends continuously or in sections over the entire length of the vortex former 4. It is not absolutely necessary for the interfering body 9 to have the same length as the vortex former, but it should be at least half the length of the vortex former.
  • the interference body can also be put on.
  • FIGS. 4 to 6 show three different embodiments of the interfering body 9.
  • the interfering body 9 is a web which is inclined in the direction of the direction of rotation of the fan roller (arrow 5).
  • the web is inclined counter to the direction of rotation of the fan roller and in the embodiment according to FIG. 6, the web is at right angles to the vortex forming surface.
  • the distance a between the ends of the webs and the vortex forming surface should be 0.01 to 0.08 times the fan roller diameter D.
