Claims (12)

  1. Ventilateur à pales axiales, en particulier pour des radiateurs de véhicules automobiles, où les pales axiales (2) sont fixées sur un moyeu de ventilateur (3), caractérisé en ce que des éléments de guidage de l'air sont disposés dans la zone du moyeu et, essentiellement, sur le côté aspiration (9) des pales axiales (2), où les éléments de guidage de l'air sont configurés comme des stabilisateurs (5, 5a), en forme d'ailerons, dont l'étendue s, dans la direction circonférentielle, est dans la plage de 0,01 t ≤ s ≤ 0,40 t, où t est la distance comprise entre le bord d'attaque d'une pale axiale et le bord d'attaque d'une pale axiale voisine.
  2. Ventilateur selon la revendication 1, caractérisé en ce que l'étendue s, vue dans la direction axiale ou dans la direction d'écoulement de l'air, augmente.
  3. Ventilateur selon la revendication 2, caractérisé en ce que l'étendue s dans la zone (13), côté soufflage de l'air, est comprise entre 0,01 t et 0,05 t et, dans la zone (14), côté évacuation de l'air, va jusqu'à 0,40 t.
  4. Ventilateur selon la revendication 1 ou 2 ou 3, caractérisé en ce que la longueur 1 des stabilisateurs (5) correspond à peu près à la longueur L des pales axiales (2).
  5. Ventilateur selon la revendication 4, caractérisé en ce que le bord d'attaque (13) des stabilisateurs (5) est décalé, dans la direction d'écoulement de l'air, par rapport au bord d'attaque (7) des pales (2).
  6. Ventilateur selon la revendication 4, caractérisé en ce que le bord de fuite (14) des stabilisateurs (5) se termine par le bord de fuite (8) des pales (2).
  7. Ventilateur selon l'une quelconque des revendications précédentes 1 à 6, caractérisé en ce que les stabilisateurs (5, 5a) sont disposés dans une zone radiale r de 0 ≤ r ≤ 0,40 H, où H est l'étendue radiale (hauteur) des pales (2).
  8. Ventilateur selon l'une quelconque des revendications précédentes, caractérisé en ce qu'un embrayage à frottement visqueux (4), comprenant des ailettes de refroidissement (4') s'étendant dans le sens radial, est disposé à l'intérieur du moyeu (3).
  9. Ventilateur selon la revendication 8, caractérisé en ce qu'un élément radial (6) de la pale est associé à chaque stabilisateur (5), lequel élément radial est disposé, dans la direction de rotation A du ventilateur (1), derrière le stabilisateur (5) et, dans la direction radiale, à l'intérieur du stabilisateur (5).
  10. Ventilateur selon la revendication 9, caractérisé en ce que la surface extérieure de l'élément radial (6) de la pale passe, dans la rampe de moyeu (16), sur l'intrados (10) de la pale (2).
  11. Ventilateur selon la revendication 9 ou 10, caractérisé en ce que les surfaces (5a, 6a) du stabilisateur (5) et de l'élément radial (6) de la pale s'interpénètrent et présentent un bord d'attaque continu (17).
  12. Ventilateur selon l'une quelconque des revendications précédentes, caractérisé en ce qu'il est prévu, sur l'intrados des pales axiales, une rampe de moyeu ascendante dans le sens inverse de la direction de rotation, rampe de moyeu en amont de laquelle sont disposés les éléments de guidage de l'air, vus dans la direction d'écoulement de l'air.
