Definitions

  • the axial fan is a blower fan in which gas flow is generated in parallel with a rotary shaft.
  • the centrifugal fan is a blower fan in which gas flow at an inlet of each blade is generated in a direction of a rotary shaft but gas flow at an outlet of the blade is generated in a radial direction perpendicular to the rotary shaft.
  • the shape or material of the noise reduction portion is not limited to the above-mentioned embodiment. That is, the noise reduction portion may be formed in various shapes having a predetermined thickness as long as reducing a vortex.
  • FIG. 2 is a plan view illustrating the example of the conventional centrifugal fan
  • FIG. 5 is a graph illustrating reduction in noise of the centrifugal fan according to the exemplary embodiment of the present invention.
  • the noise reduction portion 125 for preventing vibration and noise from being caused due to the vortex generated by the fluid preferably has a width of at least 1 mm or more.
  • the thickness/width of the noise reduction portion 125 may be adjusted in consideration of effectiveness and convenience for manufacturing.
