Description

EQUIPEMENT DE VÉHICULE AUTOMOBILE CONNECTE A UN MOTEUR A COMBUSTION  MOTOR VEHICLE EQUIPMENT CONNECTED TO A COMBUSTION ENGINE
INTERNE  INTERNAL
La présente invention concerne un équipement de véhicule automobile, notamment agencé pour être connecté à un moteur à combustion interne du véhicule automobile. The present invention relates to a motor vehicle equipment, in particular arranged to be connected to an internal combustion engine of the motor vehicle.
La demande de brevet EP 2 769 074 décrit une vanne EGR utilisée pour transporter un gaz chaud recirculé, provenant de l'échappement du véhicule automobile. Ce type de vanne EGR est placé dans l'environnement immédiat du moteur à combustion.  The patent application EP 2 769 074 describes an EGR valve used to transport a hot recirculated gas from the exhaust of the motor vehicle. This type of EGR valve is placed in the immediate environment of the combustion engine.
Comme ce type de vannes, un certain nombre d'équipements périphériques aux moteurs à combustion interne sont soumis à des contraintes thermiques de plus en plus élevées tandis que les contraintes d'encombrement et de poids nécessitent de développer des équipements refroidis par un liquide de refroidissement.  Like this type of valve, a number of devices peripheral to internal combustion engines are subjected to increasing thermal stresses while space and weight constraints require the development of equipment cooled by a coolant. .
De manière standard, le principe est de créer une canalisation d'eau dans l'équipement considéré et d'y faire circuler le liquide de refroidissement disponible sur véhicule  Normally, the principle is to create a water pipe in the equipment and circulate the coolant available on vehicle
L'équipement est donc muni d'un raccord (ou spigot en anglais) d'entrée et d'un raccord de sortie qui permettent d'amener et de récupérer le liquide de refroidissement qui aura entre les deux absorbé les calories de la pièce que l'on cherche a refroidir.  The equipment is thus provided with a connection (or spigot in English) input and an outlet connection which allow to bring and recover the coolant which will have between the two absorbed the calories of the room that we try to cool.
L'inconvénient d'une telle architecture est la multiplication des durites (métallique, plastique ou caoutchoucs) qui posent des problèmes d'intégration et de fiabilité (fuite au niveau des durites ou des colliers).  The disadvantage of such an architecture is the multiplication of hoses (metal, plastic or rubbers) which pose problems of integration and reliability (leakage at the hoses or collars).
L'invention vise à résoudre ces inconvénients. The invention aims to solve these disadvantages.
L'invention a ainsi notamment pour objet un équipement de véhicule automobile, notamment agencé pour être connecté à un moteur à combustion interne du véhicule automobile, cet équipement comprenant :  The invention thus particularly relates to a motor vehicle equipment, in particular arranged to be connected to an internal combustion engine of the motor vehicle, this equipment comprising:
- un composant à refroidir, - un organe de refroidissement comportant au moins un conduit d'amenée agencé pour amener vers le composant à refroidir, un fluide de refroidissement d'un circuit de refroidissement du véhicule automobile, cet organe de refroidissement étant assemblé avec le composant à refroidir, en appui l'un contre l'autre, de sorte que le fluide de refroidissement provenant du conduit d'amenée puisse refroidir le composant à refroidir. Grâce à l'invention, il est possible d'assurer un refroidissement sans nécessité de tuyauterie entre les différentes pièces. L'invention permet ainsi d'avoir un équipement compact et de simplifier la réalisation de la circulation de liquide de refroidissement dans le composant à refroidir. a component to be cooled, a cooling member comprising at least one supply duct arranged to supply a cooling fluid of a cooling circuit of the motor vehicle to the component to be cooled, this cooling member being assembled with the component to be cooled, in support of against each other, so that the cooling fluid from the supply line can cool the component to be cooled. Thanks to the invention, it is possible to provide cooling without the need for piping between the different parts. The invention thus makes it possible to have compact equipment and to simplify the production of the coolant circulation in the component to be cooled.
De plus l'invention permet de conserver une zone d'échange thermique équivalente à l'existant à proximité de la zone moteur.  In addition, the invention makes it possible to maintain a heat exchange zone equivalent to the existing one near the motor zone.
Avantageusement le composant à refroidir est en appui contre l'organe de refroidissement avec interposition d'un organe d'étanchéité entre le composant à refroidir et l'organe de refroidissement.  Advantageously, the component to be cooled bears against the cooling member with the interposition of a sealing member between the component to be cooled and the cooling member.
L'organe d'étanchéité est de préférence un joint.  The sealing member is preferably a seal.
Par exemple le joint est réalisé en FKM, HNBR, EPDM, ACM, acier.  For example the seal is made of FKM, HNBR, EPDM, ACM, steel.
Le joint peut présenter une forme plate et/ou une forme annulaire.  The seal may have a flat shape and / or an annular shape.
De préférence, le joint est comprimé lorsqu'il est en place entre le composant à refroidir et l'organe de refroidissement.  Preferably, the seal is compressed when in place between the component to be cooled and the cooling member.
Notamment le joint est entièrement disposé entre le composant à refroidir et l'organe de refroidissement.  In particular, the gasket is entirely arranged between the component to be cooled and the cooling member.
Le joint présente une épaisseur comprise entre 0.25 mm et 8 mm. Le joint comporte notamment au moins un orifice, notamment réalisé dans son épaisseur, disposé en regard d'une extrémité du conduit d'amenée de l'organe de refroidissement. The seal has a thickness of between 0.25 mm and 8 mm. The seal comprises in particular at least one orifice, in particular made in its thickness, arranged facing one end of the supply duct of the cooling member.
Le composant à refroidir est, si on le souhaite, assemblé avec l'organe de refroidissement par au moins un organe de fixation rapporté, notamment une vis, un goujon ou un organe d'encliquetage.  The component to be cooled is, if desired, assembled with the cooling member by at least one attachment member, including a screw, a pin or a detent member.
Avantageusement le composant à refroidir comporte une paroi d'échange thermique au contact de laquelle circule le fluide de refroidissement provenant du conduit d'amenée de l'organe de refroidissement.  Advantageously, the component to be cooled comprises a heat exchange wall in contact with which circulates the cooling fluid from the supply duct of the cooling member.
Dans un exemple de mise en œuvre de l'invention, le composant à refroidir comporte un corps, notamment réalisé par moulage, et la paroi d'échange thermique est formée sur ce corps.  In an exemplary implementation of the invention, the component to be cooled comprises a body, in particular made by molding, and the heat exchange wall is formed on this body.
De préférence, la paroi d'échange thermique est issue du moulage du corps.  Preferably, the heat exchange wall is derived from the molding of the body.
Dans un exemple de mise en œuvre de l'invention, la paroi d'échange thermique du corps à refroidir est agencée en regard d'une paroi complémentaire de l'organe de refroidissement de sorte que les parois en regard forment un conduit de refroidissement pour refroidir le composant à refroidir, et ce conduit de refroidissement est connecté de manière fluidique au conduit d'amenée de l'organe de refroidissement.  In an exemplary implementation of the invention, the heat exchange wall of the body to be cooled is arranged facing a complementary wall of the cooling member so that the facing walls form a cooling duct for cool the component to be cooled, and the cooling duct is fluidly connected to the supply duct of the cooling member.
Dans ce cas, la paroi d'échange thermique du composant à refroidir forme une paroi extérieure de ce composant.  In this case, the heat exchange wall of the component to be cooled forms an outer wall of this component.
Notamment la paroi complémentaire de l'organe de refroidissement est adjacente au conduit d'amenée.  In particular, the complementary wall of the cooling member is adjacent to the supply duct.
Le composant à refroidir peut comporter au moins un conduit de refroidissement comprenant une entrée agencée pour être connectée de manière fluidique au conduit d'amenée de l'organe de refroidissement.  The component to be cooled may comprise at least one cooling duct comprising an inlet arranged to be connected fluidically to the supply duct of the cooling member.
Par exemple ce conduit de refroidissement comporte une sortie agencée pour être connectée à un conduit d'évacuation du fluide de refroidissement formé sur l'organe de refroidissement. Le cas échéant, le conduit de refroidissement est formé par la paroi d'échange thermique du composant à refroidir. For example, this cooling duct has an outlet arranged to be connected to a conduit for discharging the cooling fluid formed on the cooling member. Where appropriate, the cooling duct is formed by the heat exchange wall of the component to be cooled.
En d'autres termes, ce conduit de refroidissement du composant à refroidir est formé de manière distincte de l'organe de refroidissement.  In other words, this cooling duct of the component to be cooled is formed separately from the cooling member.
Dans un exemple de mise en œuvre de l'invention, le conduit de refroidissement du composant à refroidir comporte un tronçon d'entrée et un tronçon de sortie.  In an exemplary implementation of the invention, the cooling duct of the component to be cooled comprises an inlet section and an outlet section.
Les tronçons d'entrée et de sortie peuvent être sensiblement parallèles.  The inlet and outlet sections may be substantially parallel.
Les tronçons d'entrée et de sortie sont reliés entre eux par un tronçon intermédiaire, lequel peut être sensiblement d'orientation différente de l'un des tronçons d'entrée et de sortie.  The inlet and outlet sections are interconnected by an intermediate section, which may be substantially of different orientation to one of the inlet and outlet sections.
Le tronçon intermédiaire est notamment obturé à l'une de ses extrémités par un obturateur rapporté, par exemple un bouchon, l'autre extrémité étant obturée par une portion du corps dans lequel le tronçon intermédiaire est réalisé.  The intermediate section is in particular closed at one of its ends by an attached shutter, for example a plug, the other end being closed by a portion of the body in which the intermediate section is formed.
Dans un exemple de mise en œuvre de l'invention, le conduit de refroidissement du composant à refroidir est formé entièrement sur un corps, notamment moulé, du composant à refroidir.  In an exemplary implementation of the invention, the cooling duct of the component to be cooled is formed entirely on a body, in particular molded, of the component to be cooled.
Dans ce cas, le composant à refroidir peut nécessiter la réalisation soit d'un noyau (fonderie sable) soit d'un tiroir (fonderie sous pression) dans le cas où le composant à refroidir est réalisé par moulage.  In this case, the component to be cooled may require the realization of either a core (sand casting) or a drawer (die casting) in the case where the component to be cooled is made by molding.
En variante, le conduit de refroidissement du composant à refroidir est formé au moins partiellement sur un corps, notamment moulé, du composant à refroidir, et au moins partiellement par un obturateur fixé au corps.  Alternatively, the cooling duct of the component to be cooled is formed at least partially on a body, in particular molded, the component to be cooled, and at least partially by a shutter attached to the body.
Par exemple le conduit de refroidissement comporte au moins un tronçon, notamment un tronçon intermédiaire, formé entre le corps et l'obturateur. Dans ce cas, le conduit de refroidissement du composant à refroidir a pour avantage d'être moulable sans noyau (fonderie sable) ni tiroir particulier (fonderie sous pression). For example, the cooling duct comprises at least one section, in particular an intermediate section, formed between the body and the shutter. In this case, the cooling duct of the component to be cooled has the advantage of being moldable without core (sand casting) or particular drawer (die casting).
Avantageusement l'obturateur est fixé de manière étanche sur le corps notamment par sertissage, bouterollage, soudage, brasage ou collage.  Advantageously, the shutter is sealingly attached to the body in particular by crimping, basting, welding, brazing or gluing.
Par exemple, l'obturateur est réalisé en acier, inox, laiton, aluminium.  For example, the shutter is made of steel, stainless steel, brass, aluminum.
Avantageusement le conduit de refroidissement du composant à refroidir comporte au moins un déflecteur agencé pour ménager un chemin d'écoulement du fluide de refroidissement entre une sortie de ce conduit et une sortie de ce conduit.  Advantageously, the cooling duct of the component to be cooled comprises at least one deflector arranged to provide a cooling fluid flow path between an outlet of this duct and an outlet of this duct.
Dans un exemple de mise en œuvre de l'invention, le déflecteur est formé par une pièce distincte d'un corps du composant à refroidir.  In an exemplary implementation of the invention, the deflector is formed by a separate part of a body of the component to be cooled.
Le conduit de refroidissement du composant à refroidir comporte notamment au moins une cavité dans laquelle s'étend au moins partiellement le déflecteur de manière à former au moins partiellement le conduit de refroidissement.  The cooling duct of the component to be cooled comprises in particular at least one cavity in which at least partially extends the deflector so as to form at least partially the cooling duct.
Ceci permet d'assurer que le fluide de refroidissement soit en mouvement afin de mieux refroidir la pièce à refroidir.  This ensures that the coolant is moving to better cool the room to cool.
Par exemple le déflecteur est réalisé en polymère thermoplastique, thermodurcissable ou en tôle métallique.  For example the deflector is made of thermoplastic polymer, thermosetting or sheet metal.
Si on le souhaite, le déflecteur est réalisé d'un seul tenant.  If desired, the deflector is made in one piece.
Le déflecteur peut être fixé sur le composant à refroidir. Le déflecteur est notamment monté sur l'organe de refroidissement.  The baffle can be attached to the component to be cooled. The deflector is in particular mounted on the cooling member.
Dans un exemple de mise en œuvre de l'invention, le déflecteur est encliqueté ou monté en force sur le composant à refroidir, ou en variante sur l'organe de refroidissement.  In an exemplary implementation of the invention, the baffle is snapped or mounted in force on the component to be cooled, or alternatively on the cooling member.
Le déflecteur présente au moins un coude. Le déflecteur a un contour extérieur épousant la cavité où circule le liquide de refroidissement. Le déflecteur possède une forme garantissant sa bonne mise en position dans le produit. L'avantage du déflecteur rapporté est la gestion possible de la perte de charge du flux entre les zones amont et aval où circule le liquide de refroidissement. The deflector has at least one elbow. The deflector has an outer contour conforming to the cavity in which the coolant circulates. The deflector has a shape ensuring its good positioning in the product. The advantage of the reported deflector is the possible management of the pressure drop of the flow between the upstream and downstream zones where the coolant circulates.
Ceci permet d'allonger le chemin du fluide refroidissement au sein du composant à refroidir et donc d'augmenter les échanges thermiques.  This makes it possible to lengthen the path of the cooling fluid within the component to be cooled and thus to increase the heat exchange.
Par exemple l'organe de refroidissement est réalisé en plastique, ou en métal.  For example, the cooling member is made of plastic or metal.
Par exemple, le composant à refroidir comporte une machine électrique, notamment un moteur électrique ou un alternateur, par exemple un alterno-démarreur.  For example, the component to be cooled comprises an electric machine, in particular an electric motor or an alternator, for example an alternator-starter.
Le composant à refroidir peut être monté dans un compresseur électrique, par exemple de suralimentation.  The component to be cooled can be mounted in an electric compressor, for example supercharging.
Le composant à refroidir peut être une vanne, par exemple une vanne EGR, un boîtier papillon essence, un doseur diesel, un volet by- pass, un volet de swirl.  The component to be cooled can be a valve, for example an EGR valve, a gasoline throttle body, a diesel metering device, a bypass flap, a swirl flap.
Par exemple, le composant à refroidir comporte un canal pour le passage de gaz chauds, et le composant comporte un moteur électrique à refroidir par le conduit de refroidissement.  For example, the component to be cooled comprises a channel for the passage of hot gases, and the component comprises an electric motor to be cooled by the cooling duct.
Dans un exemple de mise en œuvre de l'invention, le moteur électrique est logé dans un logement réalisé sur un corps du composant à refroidir.  In an exemplary implementation of the invention, the electric motor is housed in a housing made on a body of the component to be cooled.

On a représenté sur la figure 1 un équipement de véhicule automobilel selon un exemple de réalisation de l'invention, cet équipement étant agencé pour être connecté à un moteur à combustion interne 2 d'un véhicule automobile, cet équipement 1 comprenant : FIG. 1 shows a motor vehicle equipment according to an embodiment of the invention, this equipment being arranged to be connected to an internal combustion engine 2 of a motor vehicle, this equipment 1 comprising:
- un composant à refroidir 3,  a component to be cooled 3,
- un organe de refroidissement 4 comportant un conduit d'amenée 5 agencé pour amener vers le composant à refroidir 3, un fluide de refroidissement 6 d'un circuit de refroidissement 7 du véhicule automobile, cet organe de refroidissement 5 étant assemblé avec le composant à refroidir 3, en appui l'un contre l'autre, de sorte que le fluide de refroidissement 6 provenant du conduit d'amenée 5 puisse refroidir le composant à refroidir 3.  - A cooling member 4 comprising a supply duct 5 arranged to convey to the component to be cooled 3, a cooling fluid 6 of a cooling circuit 7 of the motor vehicle, this cooling member 5 being assembled with the component to cool 3, against each other, so that the cooling fluid 6 from the supply duct 5 can cool the component to be cooled 3.
Le composant à refroidir 3 est en appui contre l'organe de refroidissement 4 avec interposition d'un organe d'étanchéité 9 entre le composant à refroidir 3 et l'organe de refroidissement 4. L'organe d'étanchéité 9 est un joint réalisé en FKM, HNBR, EPDM, ACM, acier. The component to be cooled 3 bears against the cooling member 4 with the interposition of a sealing member 9 between the component to be cooled 3 and the cooling member 4. The sealing member 9 is a seal made of FKM, HNBR, EPDM, ACM, steel.
Le joint 9 présente une forme annulaire plate, et est comprimé lorsqu'il est en place entre le composant à refroidir 3 et l'organe de refroidissement 4.  The seal 9 has a flat annular shape, and is compressed when it is in place between the component to be cooled 3 and the cooling member 4.
Dans l'exemple décrit, le joint 9 est entièrement disposé entre le composant à refroidir 3 et l'organe de refroidissement 4.  In the example described, the seal 9 is entirely arranged between the component to be cooled 3 and the cooling member 4.
Le joint présente une épaisseur comprise entre 0.25 mm et 8 mm.  The seal has a thickness of between 0.25 mm and 8 mm.
Ce joint 9 comporte un orifice 10 réalisé dans son épaisseur, disposé en regard d'une extrémité 1 1 du conduit d'amenée 5 de l'organe de refroidissement 4.  This seal 9 comprises an orifice 10 made in its thickness, disposed opposite one end 1 1 of the supply duct 5 of the cooling member 4.
Le composant à refroidir 3 est assemblé avec l'organe de refroidissement 4 par des goujons 14.  The component to be cooled 3 is assembled with the cooling member 4 by studs 14.
Le composant à refroidir 3 comporte une paroi d'échange thermique 15 au contact de laquelle circule le fluide de refroidissement 6 provenant du conduit d'amenée 5 de l'organe de refroidissement 4.  The component to be cooled 3 comprises a heat exchange wall 15 in contact with which the cooling fluid 6 flows from the supply duct 5 of the cooling member 4.
Le composant à refroidir 3 comporte un corps 17 réalisé par moulage, et la paroi d'échange thermique 15 est formée sur ce corps 17.  The component to be cooled 3 comprises a body 17 made by molding, and the heat exchange wall 15 is formed on this body 17.
La paroi d'échange thermique 15 est issue du moulage du corps The heat exchange wall 15 is derived from the molding of the body
17. 17.
Cette paroi d'échange thermique 15 est agencée en regard d'une paroi complémentaire 18 de l'organe de refroidissement 4 de sorte que les parois 17 et 18 en regard forment un conduit de refroidissement 20 pour refroidir le composant à refroidir 3, et ce conduit de refroidissement 20 est connecté de manière fluidique au conduit d'amenée 5 de l'organe de refroidissement 4.  This heat exchange wall 15 is arranged facing a complementary wall 18 of the cooling member 4 so that the facing walls 17 and 18 form a cooling duct 20 for cooling the component to be cooled 3, and this cooling duct 20 is fluidly connected to the supply duct 5 of the cooling member 4.
La paroi d'échange thermique 15 du composant à refroidir 3 forme une paroi extérieure du corps 17.  The heat exchange wall 15 of the component to be cooled 3 forms an outer wall of the body 17.
La paroi complémentaire 18 de l'organe de refroidissement 4 est adjacente au conduit d'amenée 5. Le conduit de refroidissement 20 du composant à refroidir 3 comprend une entrée 21 agencée pour être connectée de manière fluidique au conduit d'amenée 5 de l'organe de refroidissement 4. The complementary wall 18 of the cooling member 4 is adjacent to the supply duct 5. The cooling duct 20 of the component to be cooled 3 comprises an inlet 21 arranged to be connected in fluidic manner to the supply duct 5 of the cooling member 4.
Ce conduit de refroidissement 20 comporte une sortie 22 agencée pour être connectée à un conduit d'évacuation 23 du fluide de refroidissement formé sur l'organe de refroidissement 4.  This cooling duct 20 comprises an outlet 22 arranged to be connected to a discharge duct 23 of the cooling fluid formed on the cooling member 4.
Ce conduit de refroidissement 20 est formé pour partie par la paroi d'échange thermique 15 du composant à refroidir 3.  This cooling duct 20 is formed partly by the heat exchange wall 15 of the component to be cooled 3.
Dans l'exemple décrit, ce conduit de refroidissement 20 du composant à refroidir 3 est formé de manière distincte de l'organe de refroidissement 4.  In the example described, this cooling duct 20 of the component to be cooled 3 is formed separately from the cooling member 4.
On a représenté sur la figure 2 un autre exemple de réalisation de l'invention.  FIG. 2 shows another embodiment of the invention.
L'équipement de la figure 2 diffère de celui de la figure 1 en ce que le conduit de refroidissement 20 du composant à refroidir 3 comporte un tronçon d'entrée 30 et un tronçon de sortie 31 .  The equipment of FIG. 2 differs from that of FIG. 1 in that the cooling duct 20 of the component to be cooled 3 comprises an inlet section 30 and an outlet section 31.
Les tronçons d'entrée 30 et de sortie 31 peuvent être sensiblement parallèles.  The inlet 30 and outlet 31 sections may be substantially parallel.
Les tronçons d'entrée 30 et de sortie 31 sont reliés entre eux par un tronçon intermédiaire 32, lequel est d'orientation différente de l'un des tronçons d'entrée 30 et de sortie 31 .  The inlet and outlet sections 31 and 31 are interconnected by an intermediate section 32, which is of different orientation to one of the inlet and outlet sections 30 and 31.
Le tronçon intermédiaire 32 est obturé à l'une de ses extrémités 33 par un obturateur rapporté 34 formé par un bouchon, l'autre extrémité 35 étant obturée par une portion 36 du corps 17 dans lequel le tronçon intermédiaire 32 est réalisé.  The intermediate section 32 is closed at one of its ends 33 by an attached shutter 34 formed by a plug, the other end 35 being closed by a portion 36 of the body 17 in which the intermediate section 32 is formed.
Dans l'exemple de la figure 2, le conduit de refroidissement 20 du composant à refroidir 3 est formé entièrement sur le corps 17, qui est moulé, du composant à refroidir 3.  In the example of FIG. 2, the cooling duct 20 of the component to be cooled 3 is entirely formed on the body 17, which is molded, of the component to be cooled 3.
La fabrication du corps 17 nécessite, lors du moulage, un noyau (fonderie sable) soit d'un tiroir (fonderie sous pression) compte tenu de la forme du conduit 20. Le corps 17 est réalisé en aluminium. The manufacture of the body 17 requires, during molding, a core (sand casting) or a slide (die casting) taking into account the shape of the pipe 20. The body 17 is made of aluminum.
En variante, comme illustré sur la figure 3, le conduit de refroidissement 20 du composant à refroidir 3 est formé partiellement sur le corps 17 du composant à refroidir 3, et partiellement par un obturateur 40 fixé au corps 17.  Alternatively, as illustrated in FIG. 3, the cooling duct 20 of the component to be cooled 3 is partially formed on the body 17 of the component to be cooled 3, and partially by a shutter 40 fixed to the body 17.
En effet le tronçon intermédiaire 32 est formé à l'aide du corps 17 et l'obturateur 40.  Indeed, the intermediate section 32 is formed using the body 17 and the shutter 40.
Dans ce cas, le conduit de refroidissement 20 du composant à refroidir a pour avantage d'être moulable sans noyau (fonderie sable) ni tiroir particulier (fonderie sous pression).  In this case, the cooling duct 20 of the component to be cooled has the advantage of being moldable without core (sand casting) or particular drawer (die casting).
L'obturateur 40 est fixé de manière étanche sur le corps 17 sertissage, bouterollage, soudage, brasage ou collage.  The shutter 40 is sealed to the body 17 crimping, basting, welding, soldering or gluing.
L'obturateur 40 est réalisé en acier, inox, laiton, ou aluminium et présente une partie centrale 41 en forme de plaque.  The shutter 40 is made of steel, stainless steel, brass, or aluminum and has a central part 41 in the form of a plate.
Dans l'exemple de la figure 4, le conduit de refroidissement 20 du composant à refroidir 3 comporte un déflecteur 45 agencé pour ménager un chemin d'écoulement du fluide de refroidissement entre une entrée 46 de ce conduit et une sortie 47 de ce conduit.  In the example of Figure 4, the cooling duct 20 of the component to be cooled 3 comprises a deflector 45 arranged to provide a coolant flow path between an inlet 46 of the duct and an outlet 47 of the duct.
Le déflecteur 45 est formé par une pièce distincte d'un corps 17 du composant à refroidir.  The deflector 45 is formed by a separate part of a body 17 of the component to be cooled.
Le conduit de refroidissement 20 du composant à refroidir comporte une cavité 49 dans laquelle s'étend le déflecteur 45 de manière à former le conduit de refroidissement 20.  The cooling duct 20 of the component to be cooled comprises a cavity 49 in which the deflector 45 extends so as to form the cooling duct 20.
Ceci permet d'assurer que le fluide de refroidissement soit en mouvement afin de mieux refroidir la pièce à refroidir.  This ensures that the coolant is moving to better cool the room to cool.
Le déflecteur 45 est réalisé en thermoplastique, thermodurcissable, en tole métallique, comme la tole inox, ou dans un autre matériau, d'un seul tenant.  The deflector 45 is made of thermoplastic, thermosetting, metal sheet, like the stainless steel sheet, or in another material, in one piece.
Le déflecteur 45 est fixé sur le composant à refroidir. Le déflecteur 45 est monté sur l'organe de refroidissement 3, en étant encliqueté ou monté à force sur le composant à refroidir, ou en variante sur l'organe de refroidissement. The deflector 45 is fixed on the component to be cooled. The deflector 45 is mounted on the cooling member 3, being snapped or force-fitted on the component to be cooled, or alternatively on the cooling member.
Le déflecteur 45 présente au moins un coude 50, et comporte des ailes 51 parallèles.  The deflector 45 has at least one elbow 50, and has parallel wings 51.
Le déflecteur a un contour extérieur épousant la cavité où circule le liquide de refroidissement. Le déflecteur est muni de forme garantissant sa bonne mise en position dans le produit. L'avantage du déflecteur rapporté est la gestion possible de la perte de charge du flux entre les zones amont et aval où circule le liquide de refroidissement.  The deflector has an outer contour conforming to the cavity in which the coolant circulates. The deflector is provided with a form ensuring its good positioning in the product. The advantage of the reported deflector is the possible management of the pressure drop of the flow between the upstream and downstream zones where the coolant circulates.
Ceci permet d'allonger le chemin du fluide refroidissement au sein du composant à refroidir et donc d'augmenter les échanges thermiques.  This makes it possible to lengthen the path of the cooling fluid within the component to be cooled and thus to increase the heat exchange.
On a représenté sur la figure 5 un équipement selon un exemple de mise en œuvre de l'invention, utilisant un déflecteur 45 comme dans la figure 4.  FIG. 5 shows an equipment according to an exemplary embodiment of the invention, using a deflector 45 as in FIG. 4.
Dans l'exemple décrit, le composant à refroidir 3 est une vanne EGR de circulation de gaz d'échappement d'un moteur de véhicule automobile. La vanne permet l'écoulement des gaz d'échappement le long de la ligne d'échappement du moteur et une recirculation des gaz à l'admission du moteur.  In the example described, the component to be cooled 3 is an exhaust gas flow valve EGR of a motor vehicle engine. The valve allows the flow of exhaust gases along the exhaust line of the engine and a recirculation of the gases at the intake of the engine.
De manière connue, la vanne 3 comprend le corps 17 définissant un conduit principal et un conduit auxiliaire d'écoulement du gaz, débouchant dans ledit conduit principal. Le conduit principal est destiné à être raccordé à la ligne d'échappement du moteur et le conduit auxiliaire sert à la recirculation de gaz d'échappement.  In a known manner, the valve 3 comprises the body 17 defining a main duct and an auxiliary gas flow duct, opening into said main duct. The main duct is intended to be connected to the exhaust line of the engine and the auxiliary duct serves for the recirculation of exhaust gas.
Le corps 17 comprend en outre un logement 55 pour un moteur 56 d'actionnement d'un volet de la vanne.  The body 17 further comprises a housing 55 for a motor 56 for actuating a flap of the valve.
Ce volet est mobile entre deux positions, une première position de fermeture, empêchant la communication entre les deux conduits, et une seconde position de pleine recirculation, permettant la mise en communication desdits conduits. This flap is movable between two positions, a first closed position, preventing communication between the two ducts, and a second full recirculation position, allowing the communication of said conduits.
Dans l'exemple de la figure 5, le déflecteur est déposé par l'opérateur dans la cavité. Sa forme n'autorise qu'une seule et unique position dans le conduit. Une fois l'assemblage des pièces 3 et 4 effectué, le déflecteur est bloqué de manière isostatique. La forme est ainsi étudiée afin que le déflecteur ne bouge pas sous l'effet des variations de pression du flux du liquide de refroidissement.  In the example of Figure 5, the deflector is deposited by the operator in the cavity. Its shape allows only one and only position in the conduit. Once the parts 3 and 4 are assembled, the deflector is isostatically blocked. The shape is thus studied so that the baffle does not move under the effect of pressure variations of the flow of the coolant.
Le joint 9 est logé dans une rainure annulaire 57 formée sur le composant à refroidir 3. Ce joint 9 est en appui avec sur l'organe de refroidissement 4. Le joint 9 présente une forme annulaire ou peut être sous forme de tôle plane.  The seal 9 is housed in an annular groove 57 formed on the component to be cooled 3. This seal 9 bears with the cooling member 4. The seal 9 has an annular shape or may be in the form of a flat sheet.
Le conduit de refroidissement 20 formé avec le déflecteur 45 sert à refroidir le moteur 56 du fait de la proximité du logement 55 du moteur 56 avec ce conduit de refroidissement 20.  The cooling duct 20 formed with the deflector 45 serves to cool the motor 56 due to the proximity of the housing 55 of the motor 56 with this cooling duct 20.
Bien entendu, on ne sort pas du cadre de la présente invention lorsque le composant à refroidir est différent d'une vanne. Of course, it is not beyond the scope of the present invention when the component to be cooled is different from a valve.
Par exemple, le composant à refroidir comporte une machine électrique, notamment un moteur électrique ou un alternateur, par exemple un alterno-démarreur.  For example, the component to be cooled comprises an electric machine, in particular an electric motor or an alternator, for example an alternator-starter.
Le composant à refroidir peut être monté dans un compresseur électrique, par exemple de suralimentation.  The component to be cooled can be mounted in an electric compressor, for example supercharging.
