Definitions

  • the present invention has been made in view of the above points, and suppresses the generation and growth of a tip vortex in a portion of the outer periphery of the blade that is not surrounded by a bell mouth, thereby providing a tip vortex on the propeller fan blowing side.
  • the purpose of the present invention is to reduce the noise (ie, driving noise) generated by the collision between the fan guard and the fan guard.
  • a plurality of blades 13 having a thick wall shape represented by an airfoil blade are provided on an outer peripheral surface of a hap 14 serving as a rotation center.
  • the axial height H 2 of the cylindrical portion 5 c is too small in comparison with the axial height H 0 of the outer peripheral portion P of the blade 1 3 (i.e., H 2 / H 0 to 0.25), the growth area of the tip vortex E (i.e., the portion of the outer periphery P of the blade 3 that is not surrounded by the bell mouth cylindrical portion 5c) becomes too large.
  • the effect of suppressing the growth of the tip vortex E by the cylindrical portion 5 c becomes insufficient, so that the interference sound between the tip vortex E and the fan guard 6 increases, and the axial height H 2 of the cylindrical portion 5 c Is the axial height H at the outer peripheral portion P of the blade 13.
  • the start position of the arc of the blow-side arc portion 5b of the bell mouth 5 is set at the rear edge B of each of the blades 13.
  • the distance between the trailing edge B of the blade 3 and the fan guard 6 is equal to the radius corresponding to the radius of the blow-side arc portion 5b of the bell mouth 5, so that the blowing wind speed is reduced and the blade 3
  • the airflow W blown out from the trailing edge B of the bell mouth 5 is smoothly expanded outward without peeling off from the blow-side arc 5b of the bell mouth 5, and does not disturb before reaching the fan guard 6.
  • the interference sound with the fan guard 6 can be reduced.

Abstract

Selon l'invention, le fait de supprimer la formation et la poussée d'un tourbillon d'extrémité de pale au niveau d'une partie de la circonférence extérieure d'une pale, qui n'est pas entourée d'un pavillon d'entrée d'air, permet de réduire le bruit (c.-à-d. le bruit de fonctionnement) qui serait sinon produit si le tourbillon d'extrémité de pale et une grille de protection entraient en contact. La configuration se présente de manière que H1/H0 = 0,40 à 0,65, où H1 désigne la hauteur de la partie chevauchant la partie de circonférence extérieure (P) d'une pale (13) en dehors des hauteurs axiales du pavillon d'entrée d'air (5) et H0 désigne la partie de circonférence extérieure (P) de la pale (13). Cette configuration permet de supprimer la poussée du courant de fuite (c.-à-d. le tourbillon d'extrémité de pale) entre la face de pression positive et la face de pression négative de la pale (13), au niveau de la partie de circonférence extérieure (P) de la pale (13), qui n'est pas entourée par le pavillon d'entrée d'air (5), tout en conservant le courant d'aspiration provenant de la partie de circonférence extérieure (P) de la pale (13).
