Description

La présente invention concerne un groupe motoventilateur utilisé pour le refroidissement d'un véhicule automobile.The present invention relates to a fan unit used for cooling a motor vehicle.

L'invention concerne plus particulièrement un groupe motoventilateur du type axial dont le moteur électrique d'entraînement est logé dans le moyeu de l'hélice. Ce groupe motoventilateur est monté sur un panneau muni d'une ouverture également appelée buse dans laquelle est fixé un support à plusieurs bras dont la partie centrale reçoit le moteur.The invention relates more particularly to a fan unit of the axial type, the electric drive motor of which is housed in the hub of the propeller. This fan unit is mounted on a panel provided with an opening also called a nozzle in which is fixed a support with several arms, the central part of which receives the motor.

Pour chaque véhicule, et pour chaque moteur thermique susceptible d'équiper ce véhicule, il est nécessaire d'adapter la puissance du moteur d'entraînement et la forme ainsi que la dimension extérieure de l'hélice. Cette adaptation est également rendue nécessaire, pour un même véhicule et pour un même moteur, en fonction de l'utilisation du véhicule, de la présence ou non d'une installation de climatisation, ainsi que pour permettre son adaptation au climat du pays d'utilisation.For each vehicle, and for each heat engine capable of equipping this vehicle, it is necessary to adapt the power of the drive motor and the shape as well as the external dimension of the propeller. This adaptation is also made necessary, for the same vehicle and for the same engine, depending on the use of the vehicle, the presence or not of an air conditioning installation, as well as to allow its adaptation to the climate of the country of use.

L'optimisation des caractéristiques aérodynamiques et donc du rendement du ventilateur nécessite en outre que le profil et le diamètre intérieur de la buse soient adaptés à l'hélice qui est utilisée. Il est donc nécessaire de multiplier le nombre des buses et des supports ce qui provoque un accroissement des coûts de fabrication et des difficultés d'assemblage et de montage.Optimizing the aerodynamic characteristics and therefore the efficiency of the fan further requires that the profile and the internal diameter of the nozzle are adapted to the propeller which is used. It is therefore necessary to increase the number of nozzles and supports, which causes an increase in manufacturing costs and difficulties in assembly and mounting.

Une première solution à ce problème a été décrite et représentée dans le document FR-U-2.329.851 qui propose de prévoir des éléments profilés, détachables par rupture, qui sont placés initialement dans la buse et qui sont enlevés en fonction du diamètre de l'hélice que l'on désire utiliser.A first solution to this problem has been described and represented in document FR-U-2,329,851 which proposes to provide profiled elements, detachable by rupture, which are initially placed in the nozzle and which are removed according to the diameter of the propeller that we want to use.

On constate toutefois que le dispositif de ventilation décrit et représenté dans ce document n'est pas un motoventilateur. L'hélice y est entraînée par le moteur du véhicule et la buse est solidaire du radiateur. Les deux composants du ventilateur qui doivent être positionnés précisément sont ici indépendants et il subsiste donc obligatoirement un jeu radial important entre les pales de l'hélice et le contour intérieur de la buse pour s'adapter en fonction des débattements du moteur.However, it can be seen that the ventilation device described and shown in this document is not a fan motor. The propeller is driven by the vehicle engine and the nozzle is integral with the radiator. The two components of the fan which must be precisely positioned are independent here and there must therefore necessarily be a large radial clearance between the blades of the propeller and the inner contour of the nozzle to adapt according to the deflections of the engine.

De ce fait il n'est pas possible d'adapter de manière optimale le profil de la buse et ses caractéristiques aérodynamiques et l'on doit se contenter de la solution simple qui est décrite dans ce document et qui consiste à réduire la canalisation de l'air autour des pales à une simple couronne annulaire de quelques millimètres d'épaisseur. La solution décrite et représentée dans ce document ne trouve donc à s'appliquer que pour les véhicules équipés de moteurs qui ne nécessitent pas un refroidissement performant tels que les moteurs fixes de groupes électrogènes ou, comme cela est indiqué dans le document, les moteurs équipant les tracteurs agricoles.Therefore it is not possible to optimally adapt the profile of the nozzle and its aerodynamic characteristics and one must be content with the simple solution which is described in this document and which consists in reducing the channeling of the air around the blades with a simple annular crown a few millimeters thick. The solution described and represented in this document therefore only applies to vehicles equipped with engines which do not require efficient cooling such as fixed engines of generator sets or, as indicated in the document, the engines fitted agricultural tractors.

L'invention a pour but de proposer une structure permettant de résoudre le problème de l'installation, dans une buse unique, d'hélices de diamètres et de profils différents.The object of the invention is to propose a structure making it possible to solve the problem of installing, in a single nozzle, propellers of different diameters and profiles.

Dans ce but l'invention propose un groupe motoventilateur du type axial comportant un moteur dont l'arbre de sortie du rotor porte une hélice qui est reçue dans une buse d'un panneau sur lequel est fixé le moteur, caractérisé en ce que les dimensions de la buse sont adaptées aux diamètres extérieurs et aux caractéristiques aérodynamiques d'une première hélice et qu'il est prévu au moins une virole intermédiaire susceptible d'être montée dans la buse pour permettre son adaptation aux caractéristiques d'au moins une deuxième hélice de plus petites dimensions.To this end, the invention provides an axial type fan unit comprising a motor, the rotor output shaft of which carries a propeller which is received in a nozzle of a panel on which the motor is fixed, characterized in that the dimensions of the nozzle are adapted to the outside diameters and to the aerodynamic characteristics of a first propeller and that at least one intermediate ferrule capable of being mounted in the nozzle is provided to allow its adaptation to the characteristics of at least one second propeller of smaller dimensions.

Selon d'autres caractéristiques de l'invention :

  • la virole intermédiaire comporte un anneau cylindrique extérieur qui est monté dans la buse et un anneau cylindrique coaxial dont les dimensions sont adaptées au diamètre extérieur et aux caractéristiques aérodynamiques de la deuxième hélice ;

  • le moteur est fixé au panneau par des bras radiaux de liaison qui sont alignés angulairement avec les ponts de liaison de la virole ; et

According to other characteristics of the invention:
  • the intermediate ferrule comprises an external cylindrical ring which is mounted in the nozzle and a coaxial cylindrical ring whose dimensions are adapted to the external diameter and to the aerodynamic characteristics of the second propeller;
  • the two rings of the ferrule are connected together by a veil which extends in a plane perpendicular to the axis of the ferrule;
  • the connecting veil has openings for the flow of air;

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :

Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is a schematic front view of a panel equipped with a fan unit produced in accordance with the teachings of the invention and in the nozzle of which is mounted the first propeller of larger diameter;
  • Figure 2 is a simplified view in partial section along line 2-2 of Figure 1;
  • Figure 3 is a view similar to that of Figure 2 which shows on an enlarged scale the nozzle equipped with a smaller propeller and an intermediate ferrule; and
  • FIG. 4 is a front view of the intermediate shell illustrated in FIG. 3.

On a illustré aux figures 1 et 2 un panneau 10 qui comporte une ouverture 12 également appelée buse, d'axe de révolution X-X.Illustrated in Figures 1 and 2 a panel 10 which has an opening 12 also called nozzle, of axis of revolution X-X.

La buse 12 permet le montage d'un motoventilateur 14 qui est constitué par un moteur électrique 16 dont l'axe du rotor (non représenté) entraîne en rotation une hélice 18.The nozzle 12 allows the mounting of a fan motor 14 which is constituted by an electric motor 16 whose axis of the rotor (not shown) rotates a propeller 18.

L'hélice 18 comporte des pales 20.The propeller 18 has blades 20.

Le moteur 16 est fixé au panneau 10 par des bras radiaux de liaison 22 qui sont ici représentés au nombre de quatre et qui sont répartis régulièrement de manière angulaire autour de l'axe X-X.The motor 16 is fixed to the panel 10 by radial connecting arms 22 which are here represented four in number and which are regularly distributed angularly around the axis X-X.

Le panneau comporte également des évidements 23 qui permettent un refroidissement dynamique du compartiment moteur du véhicule équipé du panneau 10.The panel also includes recesses 23 which allow dynamic cooling of the engine compartment of the vehicle equipped with the panel 10.

Dans l'agencement illustré aux figures 1 et 2, la buse 12 est équipée de l'hélice 18 de plus grand diamètre et le contour et le diamètre intérieur de la buse 12 sont adaptés au profil extérieur et au diamètre extérieur de cette hélice 18 de plus grand diamètre.In the arrangement illustrated in FIGS. 1 and 2, the nozzle 12 is equipped with the propeller 18 of larger diameter and the outline and the internal diameter of the nozzle 12 are adapted to the outside profile and to the outside diameter of this propeller 18 of larger diameter.

Conformément à l'invention, et afin de permettre le montage dans le panneau 10 d'une hélice 24 de plus petite dimension, il est prévu d'utiliser une virole intermédiaire 26 comme cela est illustré à la figure 3.In accordance with the invention, and in order to allow the mounting in the panel 10 of a smaller propeller 24, provision is made to use an intermediate ferrule 26 as illustrated in FIG. 3.

La virole 26 est par exemple une pièce en matière plastique constituée pour l'essentiel par un anneau cylindrique extérieur 28 et par un anneau cylindrique intérieur coaxial 30 qui sont reliés entre eux par un voile de liaison 32.The ferrule 26 is for example a plastic part consisting essentially of an external cylindrical ring 28 and a coaxial internal cylindrical ring 30 which are connected together by a connecting web 32.

Les dimensions et le profil de l'anneau cylindrique intérieur 30 de la virole intermédiaire 26 sont adaptés aux dimensions et aux caractéristiques de l'hélice de petite dimension 24.The dimensions and the profile of the inner cylindrical ring 30 of the intermediate shell 26 are adapted to the dimensions and characteristics of the small propeller 24.

L'anneau cylindrique intérieur 30 constitue donc la buse intermédiaire qui reçoit l'hélice 24.The internal cylindrical ring 30 therefore constitutes the intermediate nozzle which receives the propeller 24.

La virole intermédiaire 26 est montée dans la buse 12 par l'intermédiaire de son anneau cylindrique extérieur 28 qui est emboîté élastiquement dans la buse 12.The intermediate ferrule 26 is mounted in the nozzle 12 by means of its external cylindrical ring 28 which is resiliently fitted in the nozzle 12.

La virole intermédiaire 26 est ainsi emboîtée légèrement à force dans la buse 12 et elle est immobilisée axialement par l'intermédiaire de son bol axial d'extrémité 34 qui fait légèrement saillie radialement vers l'extérieur pour être reçu dans une gorge correspondante formée dans la buse 12.The intermediate ferrule 26 is thus slightly force-fitted into the nozzle 12 and it is immobilized axially by means of its axial end bowl 34 which projects slightly radially outward to be received in a corresponding groove formed in the nozzle 12.

Comme on peut le voir aux figures 3 et 4, le voile 32 comporte quatre ouvertures 36 pour l'écoulement de l'air qui délimitent entre elles quatre ponts de liaison 38 qui sont prévus pour être alignés angulairement avec les bras de liaison 22 du moteur 16.As can be seen in Figures 3 and 4, the web 32 has four openings 36 for the flow of air which delimit between them four connecting bridges 38 which are provided to be angularly aligned with the connecting arms 22 of the engine 16.

Il est donc ainsi possible de prévoir une série de viroles intermédiaires ayant toutes un anneau cylindrique extérieur 28 de même dimension adapté à celles de la buse 12 mais dont chacun des anneaux cylindriques intérieur 30 est de dimension et de profil adaptés à ceux de l'hélice de plus petit diamètre que l'on veut monter dans le panneau 10.It is therefore thus possible to provide a series of intermediate ferrules all having an outer cylindrical ring 28 of the same dimension adapted to those of the nozzle 12 but each of the inner cylindrical rings 30 of which are of dimension and profile adapted to those of the propeller. smaller diameter that we want to mount in the panel 10.

L'invention n'est pas limitée au mode de réalisation de la virole intermédiaire 26 qui est illustrée sur les figures, celui-ci pouvant être également assuré par exemple par rivetage, collage, etc.The invention is not limited to the embodiment of the intermediate ferrule 26 which is illustrated in the figures, which can also be provided for example by riveting, bonding, etc.

Afin de simplifier le montage des viroles intermédiaires dans la buse 12 tout en permettant un alignement angulaire correct des ponts 38 avec les bras 22, il est possible de prévoir une encoche de détrompage 40 formée à la périphérie de l'anneau extérieur 28 comme cela est illustré à la figure 4.In order to simplify the mounting of the intermediate ferrules in the nozzle 12 while allowing correct angular alignment of the bridges 38 with the arms 22, it is possible to provide a keying notch 40 formed at the periphery of the outer ring 28 as is illustrated in figure 4.
