Description
DESCRIZIONE dell'invenzione industriale dal titolo: "Ventilatore, particolarmente per un convogliatore d'aria associato ad un radiatore di un autoveicolo" DESCRIPTION of the industrial invention entitled: "Fan, particularly for an air conveyor associated with a motor vehicle radiator"
DESCRIZIONE DESCRIPTION
La presente invenzione riguarda un ventilatore,·particolarmente per un convogliatore d'aria associato ad uno scambiatore di calore, quale un radiatore, di un autoveicolo. The present invention relates to a fan, particularly for an air conveyor associated with a heat exchanger, such as a radiator, of a motor vehicle.
Più specificamente l'invenzione ha per oggetto un ventilatore comprendente un mozzo centrale da cui si estende una pluralità di pale, le cui estremità radialmente più esterne sono raccordate da un anello che nell'impiego si estende in prossimità della parete che definisce il condotto di convogliamento dell'aria. More specifically, the invention relates to a fan comprising a central hub from which a plurality of blades extends, the radially outermost ends of which are connected by a ring which in use extends near the wall that defines the conveyance duct. of the air.
Lo scopo della presente invenzione è di realizzare un ventilatore del tipo anzidetto, che sia atto a contrastare la formazione di ricircoli d'aria nell'interstizio anulare definito tra il ventilatore e la parete del convogliatore d'aria, eliminando o quantomeno sensibilmente riducendo il riflusso di aria in tale interstizio anulare verso il lato di ingresso del ventilatore. The object of the present invention is to provide a fan of the aforementioned type, which is able to counteract the formation of air recirculation in the annular interstice defined between the fan and the wall of the air conveyor, eliminating or at least significantly reducing the backflow of air in this annular gap towards the inlet side of the fan.
Questo ed altri scopi vengono realizzati secondo l'invenzione con un ventilatore assiale le cui caratteristiche salienti sono definite nell'annessa rivendicazione 1. This and other objects are achieved according to the invention with an axial fan whose salient characteristics are defined in the attached claim 1.
Ulteriori caratteristiche e vantaggi dell'invenzione appariranno dalla descrizione dettagliata che segue, effettuata a puro titolo di esempio non limitativo con riferimento ai disegni allegati, nei quali: Further characteristics and advantages of the invention will appear from the detailed description that follows, carried out purely by way of non-limiting example with reference to the attached drawings, in which:
la figura 1 è una vista parziale, in sezione assiale, di un ventilatore secondo l'invenzione e di parte dell'associato condotto di convogliamento; e Figure 1 is a partial view, in axial section, of a fan according to the invention and of part of the associated conveyance duct; And
la figura 2 è una vista parziale che mostra una variante di realizzazione di un ventilatore secondo 1'invenzione. Figure 2 is a partial view showing a variant embodiment of a fan according to the invention.
Nella figura 1 con è complessivamente indicato un ventilatore secondo l'invenzione. Tale ventilatore comprende un mozzo centrale 2, dalla cui superficie si estende una pluralità di pale sagomate 3. In figure 1 a fan according to the invention is generally indicated. This fan comprises a central hub 2, from the surface of which a plurality of shaped blades 3 extend.
Le estremità radialmente più esterne delle pale 2 sono raccordate da un anello 4 che nella condizione di impiego si estende in prossimità della parete 5 di un condotto convogliatore d’aria 6. The radially outermost ends of the blades 2 are connected by a ring 4 which in the condition of use extends near the wall 5 of an air conveyor duct 6.
Allo scopo di contrastare la formazione di ricircoli d'aria nell'interspazio anulare 7 compreso tra il ventilatore 1 e la parete 5 del convogliatore 6, dalla superficie radialmente esterna dell'anello 4 si estende una pluralità di alette 8 che possono essere angolarmente equidistanziate. In order to counteract the formation of air recirculation in the annular space 7 between the fan 1 and the wall 5 of the conveyor 6, a plurality of fins 8 extend from the radially external surface of the ring 4 which can be angularly equidistant.
Le alette 8 sono sagomate e disposte in modo tale per cui nel funzionamento generano un flusso d'aria centrifugo nell'interspazio anulare 7. The fins 8 are shaped and arranged in such a way that in operation they generate a centrifugal air flow in the annular space 7.
Nella realizzazione mostrata nella figura 1, 1'anello 4 presenta una forma essenzialmente tubolare, con un bordo circonferenziale di uscita 4a incurvato radialmente verso l'esterno, essenzialmente secondo una direzione Y che forma un angolo rispetto all'asse X del ventilatore. Le palette radiali esterne 8 dell'anello 4 possono convenientemente presentare un bordo radialmente esterno 8a la cui distanza dall'asse X del ventilatore cresce nella direzione F del flusso d'aria principale generato dalle pale 3 del ventilatore. In the embodiment shown in Figure 1, the ring 4 has an essentially tubular shape, with a circumferential outlet edge 4a curved radially outwards, essentially in a direction Y which forms an angle with respect to the X axis of the fan. The outer radial blades 8 of the ring 4 can conveniently have a radially outer edge 8a whose distance from the fan X axis increases in the direction F of the main air flow generated by the fan blades 3.
Nella figura 2 è mostrata una variante di realizzazione, in cui l'anello 4 presenta una sezione assiale sostanzialmente a forma di L, e le sue alette esterne 8 presentano corrispondentemente una forma sostanzialmente a guisa di L. Figure 2 shows a variant embodiment, in which the ring 4 has a substantially L-shaped axial section, and its external fins 8 correspondingly have a substantially L-shaped shape.
Naturalmente, fermo restando il principio del trovato, le forme di attuazione ed i particolari di realizzazione potranno essere ampiamente variati rispetto a quanto è stato descritto ed illustrato a puro titolo di esempio non limitativo, senza per questo uscire dall'ambito dell'invenzione come definito nelle annesse rivendicazioni. Naturally, the principle of the invention remaining the same, the embodiments and construction details may be widely varied with respect to what has been described and illustrated purely by way of non-limiting example, without thereby departing from the scope of the invention as defined. in the attached claims.
