Abstract
Description
<U>Ventilateur, en particulier pour souffler de l'air,</U> <U>associé à un radiateur de véhicule automobile</U> La présente invention concerne un ventilateur en particulier pour souffler de l'air, associé à un échangeur de chaleur, tel qu'un radiateur, pour véhicule automobile. A ventilator, in particular for blowing air, associated with a motor vehicle radiator. The present invention relates to a ventilator, in particular for blowing air, associated with a ventilator. heat exchanger, such as a radiator, for a motor vehicle.
Plus spécifiquement l'invention a comme objet un ventilateur comprenant un moyeu central d'où s'étendent une pluralité de pales, dont les extrémités radialement les plus à l'extérieur sont raccordées à un anneau qui, en utilisation, s'étend à proximité de la paroi définissant le conduit de soufflage de l'air. More specifically, the invention relates to a fan comprising a central hub from which a plurality of blades extend, whose radially outermost ends are connected to a ring which, in use, extends in proximity of the wall defining the air blowing duct.
Le but de la présente invention est de réaliser un ventilateur du type indiqué ci-dessus, qui soit susceptible de s'opposer à la formation de phénomènes de recirculation d'air dans l'interstice annulaire défini entre le ventilateur et la paroi du conduit de soufflage de l'air, éliminant ou au moins réduisant sensiblement le reflux d'air dans cet interstice annulaire, vers le côté d'entrée du ventilateur. The object of the present invention is to provide a fan of the type indicated above, which is likely to oppose the formation of air recirculation phenomena in the annular gap defined between the fan and the wall of the duct. blowing the air, eliminating or at least substantially reducing the backflow of air in this annular gap to the inlet side of the blower.
Ce but et d'autres buts sont atteints selon l'invention par un ventilateur axial caractérisé par le fait que, de la surface radialement extérieure dudit anneau, s'étendent une pluralité d'ailettes externes, susceptibles de générer en fonctionnement un flux d'air centrifuge. This and other objects are achieved according to the invention by an axial fan characterized in that, from the radially outer surface of said ring, extend a plurality of external fins, capable of generating in operation a flow of centrifugal air.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée allant suivre, donnée à pur type d'exemple non limitatif, en référence aux dessins annexés, dans lesquels la figure 1 est une vue partielle, en coupe axiale, d'un ventilateur selon l'invention et de parties du conduit de soufflage associées ; et la figure 2 est une vue partielle représentant une variante de réalisation d'un ventilateur selon l'invention. Other features and advantages of the invention will appear on reading the following detailed description, given in a purely nonlimiting example, with reference to the appended drawings, in which FIG. 1 is a partial view, in axial section. , a fan according to the invention and parts of the associated blowing duct; and Figure 2 is a partial view showing an alternative embodiment of a fan according to the invention.
Sur la figure 1 on a désigné globalement par 1 un ventilateur selon l'invention. Ce ventilateur comprend un moyeu central 2, de la surface duquel s'étend une pluralité de pales profilées 3. In Figure 1 is designated generally by 1 a fan according to the invention. This fan comprises a central hub 2, the surface of which extends a plurality of profiled blades 3.
Les extrémités radialement les plus à l'extérieur des pales 2 sont raccordées à un anneau 4 qui, dans les conditions d'utilisation, s'étend à proximité de la paroi 5 d'un conduit de soufflage d'air<B>6.</B> The radially outermost ends of the blades 2 are connected to a ring 4 which, under the conditions of use, extends close to the wall 5 of an air blast duct <B> 6. </ B>
Dans le but de s'opposer à la formation de recirculations d'air dans l'interstice annulaire 7, constitué entre le ventilateur 1 et la paroi 5 du conduit de soufflage 6, depuis la surface radialement extérieure de l'anneau 4 s'étendent une pluralité d'ailettes 8 qui peuvent être angulairement équidistantes. In order to oppose the formation of air recirculation in the annular gap 7, formed between the fan 1 and the wall 5 of the blowing duct 6, from the radially outer surface of the ring 4 extend a plurality of fins 8 which can be angularly equidistant.
Les ailettes 8 sont profilées et sont disposées de manière à ce qu'en fonctionnement elles génèrent un flux d'air centrifuge dans l'interstice annulaire 7. The fins 8 are profiled and are arranged so that in operation they generate a centrifugal air flow in the annular gap 7.
Dans le mode de réalisation représenté sur la figure 1, l'anneau 4 représente une forme sensiblement tubulaire avec un bord circonférenciel de sortie 4a incurvé radialement vers l'extérieur, essentiellement selon une direction Y formant un angle par rapport à l'axe X du ventilateur. Les palettes radiales externes 8 de l'anneau 4 peuvent, de manière appropriée, présenter un bord radialement externe 8a, dont la distance à l'axe X du ventilateur va en augmentant en évoluant dans la direction F du flux d'air principal généré par les pales 3 du ventilateur. Sur la figure 2, on a illustré une variante de réalisation, dans laquelle l'anneau 4 présente une section axiale sensiblement en forme de L, et ses ailettes externes 8 présentent de manière correspondante une forme sensiblement du genre d'un L. In the embodiment shown in FIG. 1, the ring 4 represents a substantially tubular shape with a radially outwardly curved circumferential exit edge 4a, essentially in a direction Y forming an angle with respect to the axis X of the fan. The outer radial vanes 8 of the ring 4 may suitably have a radially outer edge 8a, whose distance to the X axis of the fan is increasing while moving in the direction F of the main air flow generated by blades 3 of the fan. In Figure 2, there is illustrated an alternative embodiment, wherein the ring 4 has a substantially L-shaped axial section, and its outer fins 8 correspondingly have a shape substantially like an L.
Naturellement, tout en restant dans le principe de l'invention, les formes de réalisation et les détails de réalisation peuvent êtres grandement modifiés par rapport à ce qui a été décrit et illustré à pur titre d'exemple non limitatif, sans pour cela quitter le champ de l'invention, tel que défini.Naturally, while remaining in the principle of the invention, the embodiments and details of embodiment can be greatly modified with respect to what has been described and illustrated by way of non-limiting example, without leaving the scope of the invention, as defined.
