Description

L'invention concerne un dispositif de refroidissement et d'amenée d'air deThe invention relates to a device for cooling and supplying air from

combustion au moteur d'un véhicule automobile, comprenant un radiateur de refroidissement qui comporte un faisceau de radiateur et des boîtes à eau pourvues de raccords d'eau de refroidissement, ainsi qu'un conduit d'aspiration pour l'air de combustion, qui est pourvu d'un orifice d'admission. Des radiateurs de ce type sont généralement connus. L'espace avant ou zone frontale d'un véhicule automobile est fréquemment étanchéité à l'égard de l'entrée de vent relatif. Seul le radiateur est exposé au courant d'air. Un orifice d'aspiration est en outre laissé libre pour l'amenée d'air de combustion au moteur à combustion interne. Une manche d'air de refroidissement ou un canal d'aspiration mène au moteur à partir de cet orifice d'aspiration (voir DE 41 23 038 A1 et DE 39 076 C1). Le canal d'aspiration se trouve à côté du radiateur et possède une  engine combustion of a motor vehicle, comprising a cooling radiator comprising a radiator bundle and water boxes with cooling water connections, and a combustion air suction pipe, which is provided with an intake port. Radiators of this type are generally known. The front space or frontal area of a motor vehicle is frequently sealed with respect to the relative wind inlet. Only the radiator is exposed to the air current. A suction port is further left free for the supply of combustion air to the internal combustion engine. A cooling air sleeve or a suction channel leads to the engine from this suction port (see DE 41 23 038 A1 and DE 39 076 C1). The suction channel is next to the radiator and has a

fixation séparée.separate fixation.

En raison de la disposition du canal ou des canaux d'aspiration latéralement à côté du radiateur, on ne dispose que d'une place restreinte pour leur fixation. Cette limitation de la place disponible a également un effet négatif sur la grandeur des boîtes à eau. En outre, en raison des fixations séparées du radiateur et du canal d'aspiration, le montage et la dépose en cas de réparation demandent un  Due to the arrangement of the channel or suction channels laterally adjacent to the radiator, there is only a limited place for their attachment. This limitation of the available space also has a negative effect on the size of the water boxes. In addition, because of the separate fastenings of the radiator and the suction channel, assembly and removal in case of repair require a

temps de travail non négligeable.not negligible working time.

La présente invention a donc pour but de créer un dispositif, du type mentionné au début, dont la structure et le montage soient simples et qui ne pose  The present invention therefore aims to create a device, of the type mentioned at the beginning, whose structure and assembly are simple and not pose

pas de problèmes de place.no problems of place.

Conformément à l'invention, on obtient ce résultat par le fait que l'une au moins des boîtes à eau est dotée d'un évidement servant d'orifice d'admission  According to the invention, this result is achieved by the fact that at least one of the water boxes is provided with a recess serving as an inlet

pour le conduit d'aspiration.for the suction duct.

Selon l'invention, l'orifice d'admission pour le conduit d'aspiration est intégré dans l'une ou dans les deux boîtes à eau, lesquelles sont placées généralement à côté du faisceau de radiateur. Il suffit à cet effet de doter la ou les boîtes à eau d'un évidement adéquat, par exemple sous la forme d'une ouverture ronde ou ovale. A cette ouverture, pouvant être munie d'une tubulure de raccordement sur le côté arrière de la boîte à eau, se raccorde alors de manière simple le conduit d'aspiration pour l'air de combustion. Cela signifie non seulement que la solution selon l'invention demande moins de pièces - c'est ainsi que la manche et le matériel pour sa fixation sont supprimés -, mais que le travail de  According to the invention, the intake port for the suction duct is integrated in one or both water boxes, which are placed generally next to the radiator bundle. It suffices for this purpose to provide the water box or boxes with a suitable recess, for example in the form of a round or oval opening. At this opening, which can be provided with a connecting pipe on the rear side of the water box, then simply connects the suction duct for combustion air. This means not only that the solution according to the invention requires fewer pieces - thus the sleeve and the material for its attachment are removed - but that the work of

montage et de dépose est également moindre.  mounting and removal is also lesser.

De plus, l'étanchéité de la zone environnante, autour du dispositif, peut être réalisée bien plus simplement. En vue de la fixation du radiateur par l'intermédiaire des boîtes à eau, celles-ci peuvent également être rendues plus grandes, donc plus robustes, du fait que la surface de fixation est plus grande. Cela veut dire qu'une base nettement plus grande donc plus sûre est créée pour la fixation du dispositif Il s'y ajoute que pour le même encombrement en largeur, en raison de la suppression du conduit d'aspiration - placé à côté du radiateur selon l'état actuel de la technique - et de la distance de sécurité à prévoir entre le radiateur et la manche ou le conduit d'aspiration connu, on dispose d'une aire de section nettement plus grande pour l'aspiration. Il en va de même pour les dimensions des boîtes à eau. D'autres caractéristiques et avantages de l'invention ressortiront plus  In addition, the tightness of the surrounding area around the device can be achieved much more simply. In order to fix the radiator through the water boxes, these can also be made larger, and therefore more robust, because the fixing surface is larger. This means that a much larger and therefore safer base is created for the attachment of the device. In addition, it is necessary for the same overall width, due to the elimination of the suction pipe - placed next to the radiator according to the current state of the art - and the safety distance to be provided between the radiator and the sleeve or the known suction pipe, there is a much larger sectional area for suction. The same goes for the dimensions of the water boxes. Other features and advantages of the invention will emerge more

clairement de la description qui va suivre d'un exemple de réalisation non limitatif,  clearly from the following description of a nonlimiting exemplary embodiment,

ainsi que des dessins schématiques annexés, sur lesquels: * la figure 1 est une perspective partielle du dispositif selon l'invention, prise de l'avant; et + la figure 2 est une vue partielle semblable de ce dispositif, mais prise de l'arrière. Le dispositif de refroidissement et d'amenée d'air de combustion au moteur - non représenté - d'un véhicule automobile comprend un radiateur 1 avec un faisceau de radiateur 2 et deux boîtes à eau 3 accolées latéralement à ce faisceau et pourvues de raccords d'eau de refroidissement non représentés. Entre le faisceau de radiateur 2 et chacune des boîtes à eau 3 se trouve en outre une plaque à tubes 4, dans laquelle sont fixés les tubes du faisceau de radiateur et sur laquelle est bridée la boîte à eau 3 coordonnée. La partie supérieure d'une ou des deux boîtes à eau 3 présente un évidement sous la forme d'une ouverture ovale 5. Cette ouverture sert d'orifice d'admission d'air de combustion. L'ouverture 5 est réalisée comme un trou traversant et pourvue, sur son côté arrière, c'est-à-dire du côté dirigé vers le véhicule, d'une tubulure de raccordement 6 pour le branchement d'un conduit  and schematic drawings attached, in which: * Figure 1 is a partial perspective of the device according to the invention, taken from the front; and + Figure 2 is a similar partial view of this device, but taken from the rear. The device for cooling and supplying combustion air to the motor (not shown) of a motor vehicle comprises a radiator 1 with a radiator bundle 2 and two water boxes 3 contiguous laterally to this bundle and provided with couplings. cooling water not shown. Between the radiator bundle 2 and each of the water boxes 3 is furthermore a tube plate 4, in which the tubes of the radiator bundle are fixed and on which the coordinated water box 3 is clamped. The upper part of one or both water boxes 3 has a recess in the form of an oval opening 5. This opening serves as a combustion air inlet. The opening 5 is made as a through hole and provided, on its rear side, that is to say on the side facing the vehicle, a connecting pipe 6 for the connection of a conduit

d'aspiration non représenté servant à amener de l'air de combustion au moteur.  suction nozzle not shown for supplying combustion air to the engine.

Ainsi que cela ressort des deux figures, l'intégration de l'orifice d'admission dans la boîte à eau 3 apporte, comme avantage supplémentaire, une surface nettement plus grande dans la partie supérieure de la boîte pour la mise en place d'éléments de fixation 7 qui sont seulement indiqués schématiquement sur le dessin. Sur le côté arrière, la boîte à eau 3 est munie de raccords 8 pour le  As is apparent from the two figures, the integration of the inlet orifice in the water box 3 provides, as an additional advantage, a much larger area in the upper part of the box for the introduction of elements. 7 which are only indicated schematically in the drawing. On the back side, the water box 3 is provided with connectors 8 for the

refroidissement de l'huile de transmission et 9 pour la purge d'air du radiateur.  cooling of the transmission oil and 9 for the purge of air from the radiator.

Grâce à la possibilité de réaliser une fixation stable du radiateur 1 par les éléments de fixation 7, le dispositif peut servir en même temps aussi comme support pour le condenseur d'un système de climatisation, un refroidisseur d'air d'alimentation et/ou un ventilateur aspirant (non représentés).5 Comme on peut le voir sur les dessins, grâce à la forme du radiateur avec la manche à air froid ou l'orifice d'admission intégré, on peut également  Thanks to the possibility of achieving a stable fixation of the radiator 1 by the fastening elements 7, the device can be used at the same time also as a support for the condenser of an air conditioning system, a supply air cooler and / or a suction fan (not shown) .5 As can be seen in the drawings, thanks to the shape of the radiator with the cold windsock or the integrated intake port, it is also possible to

obtenir une étanchéification très simple de la zone environnante.  get a very simple sealing of the surrounding area.
