Description

Domaine techniqueTechnical area

La présente invention concerne le domaine technique des équipements de véhicules automobiles, notamment les équipements d'alimentation en air des moteurs de véhicules automobiles et plus particulièrement aux moteurs dont l'air d'alimentation provient d'un compresseur ou d'un turbocompresseur.The present invention relates to the technical field of motor vehicle equipment, in particular air supply equipment for motor vehicle engines and more particularly to engines whose supply air comes from a compressor or a turbocharger.

État de la techniqueState of the art

L'air d'alimentation provenant d'un compresseur ou d'un turbocompresseur est aussi appelé « air de suralimentation ».Supply air from a compressor or turbocharger is also called "charge air".

Afin d'augmenter la densité de l'air d'admission d'un moteur turbocompressé, il est connu de refroidir l'air de suralimentation sortant du compresseur au moyen d'un échangeur de chaleur qui est aussi appelé refroidisseur d'air de suralimentation (en abrégé : RAS).In order to increase the density of the intake air of a turbocharged engine, it is known to cool the charge air leaving the compressor by means of a heat exchanger which is also called a charge air cooler. (abbreviated: RAS).

Un RAS comporte généralement un faisceau d'échange de chaleur. Ce faisceau d'échange de chaleur comporte un empilement de plaques ou de tubes formant alternativement des canaux de circulation pour l'air suralimenté à refroidir et des canaux pour la circulation de fluide caloporteur, notamment du liquide de refroidissement moteur. L'échange de chaleur entre les plaques ou les tubes et l'air de suralimentation est réalisé en partie par l'intermédiaire de turbulateurs. Le faisceau est enfermé dans un réceptacle qui de manière générale a la forme d'un cylindre droit et creux, le plus souvent à base rectangulaire, relié à l'une de ses extrémités ouvertes à une boite à air d'entrée et à l'autre à une boite à air de sortie (configuration en I, c'est-à-dire que l'air à refroidir suit un chemin en ligne droite) ; ou à une de ses extrémités ouvertes à une boite à air d'entrée et de sortie et à l'autre à une boite à air de déflexion (configuration en U, c'est-à-dire que l'air à refroidir suit un chemin coudé afin de ressortir sensiblement colinéairement à sa direction d'entrée).A RAS generally has a heat exchange bundle. This heat exchange bundle comprises a stack of plates or tubes alternately forming circulation channels for the supercharged air to be cooled and channels for the circulation of heat transfer fluid, in particular engine coolant. The heat exchange between the plates or tubes and the charge air is carried out in part by means of turbulators. The bundle is enclosed in a receptacle which generally has the shape of a straight, hollow cylinder, most often with a rectangular base, connected at one of its open ends to an inlet air box and to the another to an outlet air box (I-configuration, that is to say that the air to be cooled follows a path in a straight line); or at one of its open ends to an inlet and outlet air box and at the other to a deflection air box (U-shaped configuration, i.e. the air to be cooled follows a bent path in order to emerge substantially collinearly with its direction of entry).

Des exemples d'un tel faisceau sont décrits par les documents DE 102009053884 , FR 2822532 et DE102005008409 . Le réceptacle est relié aux boites à air par l'intermédiaire d'un collecteur, dont la forme générale est un cylindre droit à base rectangulaire à coins arrondis. Le collecteur présente une première extrémité de couplage à la boite à air et une deuxième extrémité de couplage au réceptacle du faisceau. La deuxième extrémité de couplage entoure entièrement le faisceau et est fixée à celui-ci par soudage et/ou brasage. La première extrémité de couplage comprend quatre rabats correspondant à chacun des côtés du réceptacle du faisceau ; les arrondis au niveau des coins étant laissés dénués de rabats. Lors de la fixation du faisceau aux boites à eau, les rabats de la première extrémité du collecteur sont sertis sur une surface extérieure de la boite à air correspondante. Ainsi, la fixation est réalisée le long des rabats à l'exception des coins. Cette fixation en combinaison avec un joint assure l'étanchéité du RAS aux interfaces entre collecteurs et boites à eau.Examples of such a beam are described by documents FROM 102009053884 , FR 2822532 and DE102005008409 . The receptacle is connected to the air boxes by means of a manifold, the general shape of which is a straight cylinder with a rectangular base with rounded corners. The collector has a first end of coupling to the airbox and a second coupling end to the harness receptacle. The second coupling end completely surrounds the bundle and is attached to it by welding and / or brazing. The first coupling end includes four flaps corresponding to each of the sides of the harness receptacle; the rounded corners being left devoid of flaps. When attaching the harness to the water boxes, the flaps of the first end of the manifold are crimped onto an outer surface of the corresponding air box. Thus, the fixing is carried out along the flaps except for the corners. This fixing in combination with a seal ensures the tightness of the RAS at the interfaces between manifolds and water boxes.

Les boites à eau du RAS subissent des contraintes dues à la force exercée par les liquides qui traversent le faisceau jusqu'aux boites. Cette force est dirigée suivant une direction colinéaire à la génératrice du cylindre droit formé par le réceptacle et la bride de sertissage.The RAS water boxes are subjected to stresses due to the force exerted by the liquids which pass through the beam to the boxes. This force is directed in a direction collinear with the generatrix of the right cylinder formed by the receptacle and the crimping flange.

Lors de tests, il a été observé un décollement de la boite à air du collecteur au niveau des coins. Ce décollement tend à se propager le long des rabats jouxtant le coin en question par dessertissage de ceux-ci et aboutit in fine à la perte d'étanchéité du RAS à ces interfaces.During tests, it was observed a detachment of the air box from the manifold at the corners. This detachment tends to propagate along the flaps adjoining the corner in question by unscrewing them and ultimately results in the loss of tightness of the RAS at these interfaces.

Le document EP 0 054 815 A1 divulgue un article serti selon le pröambule de la revendication 1.The document EP 0 054 815 A1 discloses a crimped article according to the preamble of claim 1.

Présentation de l'inventionPresentation of the invention

Ainsi, un objectif de la présente invention est de palier un des inconvénients de l'état de la technique décrite ci-dessus, et notamment garantir la fixation entre le collecteur et la boite à air.Thus, an objective of the present invention is to overcome one of the drawbacks of the state of the art described above, and in particular to guarantee the attachment between the manifold and the air box.

Pour cela, la présente invention propose un article serti comprenant :

  • un couvercle présentant un coin ;
  • une bride de sertissage présentant au moins une encoignure dont la forme correspond à celle du coin du couvercle ; et
dans lequel une partie de l'encoignure de la bride de sertissage est sertie sur une surface du coin du couvercle; et dans lequel la surface du coin est creuse.For this, the present invention provides a crimped article comprising:
  • a cover having a corner;
  • a crimping flange having at least one corner whose shape corresponds to that of the corner of the cover; and
wherein a portion of the corner of the crimping flange is crimped on a surface of the corner of the cover; and in which the surface of the wedge is hollow.

Ainsi, grâce au sertissage des coins, l'amorce du décollement est évité ; il ne peut donc se propager par la suite aux portions serties jouxtant les coins.Thus, thanks to the crimping of the corners, the onset of detachment is avoided; it cannot therefore propagate subsequently to the crimped portions adjoining the corners.

D'autres caractéristiques optionnelles et non limitatives sont présentées ci-dessous.Other optional and non-limiting characteristics are presented below.

The shape of the concave hollow surface is advantageously chosen so that a line on the concave hollow surface marked by a free edge of the crimped portion of the notch on the corner has a length equal to ± 20% of the length of the 'arc of a circle of radius R1 forming the periphery of the corner.

Dans un mode particulier de réalisation, la surface creuse concave correspond à la surface d'une sphère de rayon R2 égal à ± 20 %, préférentiellement à ± 10 %, encore préférentiellement à ± 5 %, du rayon R1, toujours préférentiellement à environ R1. Avantageusement, un pôle de la sphère de rayon R2 correspond au milieu de l'arc de cercle de rayon R1.In a particular embodiment, the concave hollow surface corresponds to the surface of a sphere with radius R2 equal to ± 20%, preferentially to ± 10%, more preferably to ± 5%, of the radius R1, always preferentially around R1. . Advantageously, a pole of the sphere of radius R2 corresponds to the middle of the arc of a circle of radius R1.

La partie sertie de l'encoignure présente préférentiellement une épaisseur constante.The crimped part of the corner preferably has a constant thickness.

L'article serti peut en outre comprendre un réceptacle présentant un bord présentant une surface extérieure et une surface intérieure, la surface intérieure du bord délimitant un espace intérieur recouvert par le couvercle, le bord dessinant une forme correspondant à celle du couvercle, dans lequel la surface extérieure est en contact avec la bride de sertissage.The crimped article may further comprise a receptacle having an edge having an exterior surface and an interior surface, the interior surface of the edge defining an interior space covered by the lid, the edge forming a shape corresponding to that of the lid, in which the outer surface is in contact with the crimp flange.

L'article est en particulier un article susceptible d'être soumis à une pression dont une composante exerce une force sur le couvercle sur une surface opposée à la surface du coin sur laquelle est sertie la partie de l'encoignure, cette partie de l'encoignure exerçant alors une force opposée à celle exercée par la composante de la pression.The article is in particular an article capable of being subjected to a pressure, a component of which exerts a force on the cover on a surface opposite to the surface of the corner on which the part of the corner is crimped, that part of the corner. corner then exerting a force opposite to that exerted by the pressure component.

Un article serti selon la présente invention est décrite ci-après en référence aux figures 1 à 7.A crimped article according to the present invention is hereinafter described with reference to figures 1 to 7 .

L'article serti 1 comprend un couvercle 2, une bride de sertissage 3 et éventuellement un réceptacle 4. The crimped article 1 comprises a cover 2, a crimping flange 3 and optionally a receptacle 4.

Le couvercle 2 (comprenant généralement des parois latérales et une surface) présente un coin 21. Le coin 21 présente généralement deux parois latérales 25 (faisant notamment partie de deux parois latérales adjacentes du couvercle 2) et une surface 22 (faisant notamment partie de la surface du couvercle 2). Vu de dessus (c'est-à-dire dans une direction normale à la surface du coin 21), les deux parois latérales 25 du coin 21 forment un angle de moins de 180°. Le coin peut être arrondi ou chanfreiné, i.e. la transition entre les deux parois, vue de dessus, est un arc de cercle de préférence ayant un rayon de 4±2 mm (formant le pourtour 23 du coin), ou un chanfrein de préférence ayant une longueur de 4±2 mm. Le couvercle 2 est préférentiellement en plastique ou métal, par exemple en aluminium ou en acier.The cover 2 (generally comprising side walls and a surface) has a corner 21. The corner 21 generally has two side walls 25 (in particular forming part of two adjacent side walls of the cover 2) and a surface 22 (in particular forming part of the cover surface 2). Seen from above (i.e. in a direction normal to the surface of wedge 21), the two side walls 25 of wedge 21 form an angle of less than 180 °. The corner can be rounded or chamfered, i.e. the transition between the two walls, seen from above, is an arc of a circle preferably having a radius of 4 ± 2 mm (forming the periphery 23 of the corner), or a chamfer preferably having a length of 4 ± 2 mm. The cover 2 is preferably made of plastic or metal, for example aluminum or steel.

Selon l'invention, la surface du coin 2 est creuse, de préférence concave, sur laquelle est sertie la partie sertie de l'encoignure 311. According to the invention, the surface of the corner 2 is hollow, preferably concave, onto which the crimped part of the corner 311 is crimped.

Le coin 2 est de préférence arrondi par un arc de cercle de rayon R1. Dans ce cas, la surface creuse concave présente avantageusement une forme choisie de sorte qu'une ligne sur la surface creuse 22 concave marquée par un bord libre de la partie sertie de l'encoignure 311 sur celle-ci présente une longueur égale à ± 20 % de la longueur de l'arc de cercle de rayon R1 formant l'arrondi du coin. En d'autres termes, le matériau de la partie sertie de l'encoignure 311 présente un allongement ou une compression de ± 20% à ce niveau. De préférence, la surface creuse 22 est telle qu'elle présente un point de plus bas niveau 211 sur l'arrondi du coin 21 et un point de plus haut niveau 212, et que quelle que soit la hauteur à laquelle une coupe est réalisée entre le point de plus bas niveau 211 et le point de plus haut niveau 212, parallèlement à un plan moyen du couvercle 2 passant par ses parois latérales, la distance L2 du pourtour 23 du coin 2 à cette hauteur est :
L2 = L1 ±20 %, de préférence L2 = L1 ± 10%, toujours de préférence L2 = L1 ± 5%, encore de préférence L2 = L1 ;
avec L1 la longueur du pourtour du coin à la hauteur du point de plus bas niveau.The corner 2 is preferably rounded by an arc of a circle of radius R1. In this case, the concave hollow surface advantageously has a shape chosen so that a line on the concave hollow surface 22 marked by a free edge of the crimped part of the corner 311 thereon has a length equal to ± 20 % of the length of the circular arc of radius R1 forming the rounding of the corner. In other words, the material of the crimped portion of the corner 311 exhibits an elongation or compression of ± 20% at this level. Preferably, the hollow surface 22 is such that it has a point of lowest level 211 on the rounding of the corner 21 and a point of highest level 212, and that regardless of the height at which a cut is made between the lowest level point 211 and the highest level point 212, parallel to a mean plane of the cover 2 passing through its side walls, the distance L 2 from the periphery 23 of the corner 2 at this height is:
L 2 = L 1 ± 20%, preferably L 2 = L 1 ± 10%, always preferably L 2 = L 1 ± 5%, more preferably L 2 = L 1 ;
with L 1 the length of the perimeter of the corner at the height of the lowest level point.

Un exemple d'une telle forme est illustré par la figure 6. Celui-ci est obtenu lorsque la surface creuse concave correspond à la surface d'une sphère de rayon R2 égal à ± 20 %, préférentiellement à ± 10 %, encore préférentiellement à ± 5 %, du rayon R1, toujours préférentiellement à environ R1. Avantageusement, le point de plus bas niveau est situé au milieu de l'arc de cercle de rayon R1.An example of such a shape is illustrated by the figure 6 . This is obtained when the concave hollow surface corresponds to the surface of a sphere with a radius R2 equal to ± 20%, preferably to ± 10%, more preferably to ± 5%, of the radius R1, always preferably to approximately R1. Advantageously, the point of lowest level is located in the middle of the arc of a circle of radius R1.

Le couvercle 2 peut présenter un contour 24 dont fait partie le coin 21. The cover 2 may have a contour 24 of which the corner 21 forms part.

Avant sertissage, la bride de sertissage 3 présente au moins une encoignure 31 dont la forme correspond à celle combinée des deux parois latérales 25 du coin 21 du couvercle 2. L'encoignure 31 comprend deux parois internes formant un angle correspondant à celui formé par les parois latérales du coin 2. L'encoignure peut être arrondie quand le coin est arrondi, i.e. la transition entre les deux parois de l'encoignure forme un arc de cercle correspondant à celui du coin, de préférence de rayon 4±2 mm. L'encoignure peut encore être chanfreinée quand le coin est chanfreiné, i.e. la transition est un chanfrein correspondant à celui du coin, de préférence de largeur 4±2 mm. Une partie de l'encoignure de la bride de sertissage 3 est sertie sur la surface 22 du coin 21 du couvercle 2. Before crimping, the crimping flange 3 has at least one corner 31 , the shape of which corresponds to the combined shape of the two side walls 25 of the corner 21 of the cover 2. The corner 31 comprises two internal walls forming an angle corresponding to that formed by the side walls of corner 2. The corner can be rounded when the corner is rounded, ie the transition between the two walls of the corner forms an arc of circle corresponding to that of the corner, preferably of radius 4 ± 2 mm. The corner can still be chamfered when the corner is chamfered, ie the transition is a chamfer corresponding to that of the corner, preferably of width 4 ± 2 mm. A part of the corner of the crimping flange 3 is crimped on the surface 22 of the corner 21 of the cover 2.

Typiquement avant sertissage, la bride de sertissage 3 peut présenter une paroi cylindrique dont fait partie la partie de l'encoignure 311 destinée à être sertie et correspondant au contour 24 du couvercle et après sertissage une partie de la paroi cylindrique est sertie au moins en partie, de préférence en totalité, sur le contour 24 du couvercle.Typically before crimping, the crimping flange 3 can have a cylindrical wall of which the part of the corner 311 intended to be crimped and corresponding to the contour 24 of the cover forms part and after crimping a part of the cylindrical wall is at least partially crimped. , preferably in its entirety, on the contour 24 of the cover.

La bride de sertissage 3 peut comprendre une première extrémité de couplage 32 au couvercle 2, dont fait partie l'encoignure 31, et une deuxième extrémité de couplage 33 à un autre élément, tel que le réceptacle 4, afin de fixer le couvercle 2 à cet autre élément.The crimping flange 3 may include a first coupling end 32 to the cover 2, of which the corner 31 is a part, and a second coupling end 33 to another element, such as the receptacle 4, in order to secure the cover 2 to this other element.

La première extrémité de couplage 32 peut comprendre une partie rabattue 321 sur le couvercle 2 après sertissage et une partie de contact 322 en contact avec les parois latérales du couvercle 2. Avant sertissage, la limite entre la partie rabattue 321 et la partie de contact 322 est généralement parallèle au plan moyen de la première extrémité de couplage 32, cette limite marque le pliage de la partie rabattue 321 par rapport à la partie de contact 322. Après sertissage, la droite normale à la partie rabattue 321 et celle à la partie de contact 322 sont de préférence orthogonales entre elles, à l'exception éventuelle du ou des coins.The first coupling end 32 may include a folded portion 321 on the cover 2 after crimping and a contact portion 322 in contact with the side walls of the cover 2. Before crimping, the boundary between the folded portion 321 and the contact portion 322 is generally parallel to the mean plane of the first coupling end 32, this limit marks the bending of the folded part 321 with respect to the contact part 322. After crimping, the line normal to the folded part 321 and that to the part of contact 322 are preferably mutually orthogonal, with the possible exception of the corner or corners.

De préférence, l'encoignure 31 est conservée dans la partie de contact 322 pendant le sertissage et déformée seulement dans la partie rabattue 321.Preferably, the notch 31 is retained in the contact portion 322 during crimping and deformed only in the folded portion 321.

La bride de sertissage 3 est préférentiellement en métal, par exemple en aluminium ou acier.The crimping flange 3 is preferably made of metal, for example aluminum or steel.

Plus particulièrement, la partie rabattue 321 de la bride de sertissage 3 peut recouvrir le couvercle 2 sur tout ou partie de son contour 24. Ici « tout le contour » doit être compris comme tout le long du contour et « partie du contour » comme signifiant avec un ou des tronçons du contour qui ne sont pas concernés.More particularly, the folded-back part 321 of the crimping flange 3 can cover the cover 2 over all or part of its contour 24. Here “the entire contour” must be understood as all along the contour and “part of the contour” as meaning. with one or more sections of the contour which are not concerned.

Par ailleurs, le sertissage 322 peut être réalisé sur tout (partie basse de la figure 5) ou partie (partie haute de la figure 5) de la partie rabattue 321 de la bride de sertissage 3. Bien entendu, le sertissage 322 ne pouvant être réalisé sur toute la partie rabattue 321 que dans le cas où celle-ci recouvre le couvercle 2 sur tout son contour 24. Lorsque la partie rabattue 321 est sertie seulement en partie, le sertissage 322 est de préférence réalisé à intervalle régulier.In addition, the crimping 322 can be performed on everything (lower part of the figure 5 ) or part (upper part of the figure 5 ) of the folded part 321 of the crimping flange 3. Of course, the crimping 322 can not be performed over the entire folded part 321 unless the latter covers the cover 2 over its entire contour 24. When the folded part 321 is only partially crimped, the crimping 322 is of preferably carried out at regular intervals.

Le contour 24 du couvercle 2 est de préférence polygonal, par exemple régulièrement polygonal, de préférence rectangulaire. Il n'est pas pris en compte l'arrondi des coins pour la description de la forme générale du contour du couvercle, les coins arrondis étant assimilés aux angles de la forme générale. La partie rabattue 321 comprend autant de parties serties 311 d'encoignures que le contour 24 du couvercle présente de coins 21. The outline 24 of the cover 2 is preferably polygonal, for example regularly polygonal, preferably rectangular. The rounding of the corners is not taken into account for the description of the general shape of the contour of the cover, the rounded corners being assimilated to the angles of the general shape. The folded-down part 321 comprises as many crimped parts 311 with corners as the contour 24 of the cover has corners 21.

Lorsque la partie rabattue 321 de la bride de sertissage 3 recouvre en partie le couvercle 2 le long de son contour 24, celle-ci peut comprendre par exemple des tronçons sertis 3221 au contour 24 du couvercle et séparés les uns des autres par un espace, notamment lorsqu'avant sertissage, la première partie de couplage 32 de la bride de sertissage 3 présente une forme crènelée. Les tronçons séparés peuvent présenter des largeurs, i.e. la dimension prise dans le sens de la séparation, différentes ou égales, de préférence égales.When the folded-down part 321 of the crimping flange 3 partially covers the cover 2 along its contour 24, the latter may for example comprise crimped sections 3221 to the contour 24 of the cover and separated from each other by a space, in particular when, before crimping, the first coupling part 32 of the crimping flange 3 has a crimped shape. The separate sections can have widths, ie the dimension taken in the direction of separation, different or equal, preferably equal.

Autre exemple, lorsque le contour 24 du couvercle 2 est polygonal, la partie rabattue 321 de la bride de sertissage 3 comprend des tronçons correspondant aux côtés du polygone et dont les longueurs sont sensiblement égales à la longueur des côtés correspondant du polygone et séparés des parties serties d'encoignure 311 par un espace. Les tronçons peuvent être chacun serti sur toute ou partie de leur longueur. S'ils sont sertis sur une partie de leur longueur, le sertissage est de préférence réalisé par intervalle régulier.Another example, when the contour 24 of the cover 2 is polygonal, the folded part 321 of the crimping flange 3 comprises sections corresponding to the sides of the polygon and the lengths of which are substantially equal to the length of the corresponding sides of the polygon and separated from the parts. set with corner 311 by a space. The sections can each be crimped over all or part of their length. If they are crimped over part of their length, the crimping is preferably carried out at regular intervals.

Lorsque la partie rabattue 321 de la bride de sertissage 3 recouvre le couvercle 2 sur tout son contour 24, le sertissage peut être réalisé continument sur tout le contour 24 ou sur une partie seulement, notamment à intervalle régulier.When the folded-down portion 321 of the crimping flange 3 covers the cover 2 over its entire contour 24, the crimping can be carried out continuously over the entire contour 24 or over only a part, in particular at regular intervals.

De préférence, la partie sertie de l'encoignure 311, le cas échéant la partie rabattue 321 de la bride de sertissage 3, présente une épaisseur constante. Ainsi, la première extrémité de couplage 32 de la bride de sertissage présente de préférence une épaisseur constante. Cependant, il est également possible de prévoir que l'ensemble de la bride de sertissage 3 présente une épaisseur constante, i.e. y compris la deuxième partie de couplage. Dans le cadre du présent exposé, l'épaisseur de la bride de sertissage 3 est sa dimension la plus petite : c'est celle qui est perpendiculaire à la surface du couvercle lorsque une fois sertie, et éventuellement à celle du réceptacle 4, à laquelle la bride de sertissage 3 est couplé. De préférence, cette épaisseur constante est comprise entre 0,8 mm et 3 mm.Preferably, the crimped part of the corner 311, where appropriate the folded part 321 of the crimping flange 3, has a constant thickness. Thus, the first coupling end 32 of the crimping flange preferably has a constant thickness. However, it is also possible to provide that the assembly of the crimping flange 3 has a constant thickness, ie including the second part of coupling. In the context of the present disclosure, the thickness of the crimping flange 3 is its smallest dimension: it is that which is perpendicular to the surface of the cover when once crimped, and possibly to that of the receptacle 4, to which the crimping flange 3 is coupled. Preferably, this constant thickness is between 0.8 mm and 3 mm.

Le réceptacle 4 présente généralement un bord présentant une surface extérieure et une surface intérieure. La surface intérieure du bord délimite un espace intérieur recouvert par le couvercle 2. Le bord dessine une forme correspondant à celle du couvercle 2. La surface extérieure du bord est en contact avec la bride de sertissage 3, notamment avec sa deuxième extrémité de couplage 33. La bride de sertissage 3 enserre la surface extérieure et y est fixée préférentiellement par brasage et/ou soudage.The receptacle 4 generally has an edge having an exterior surface and an interior surface. The inner surface of the edge defines an inner space covered by the cover 2. The edge draws a shape corresponding to that of the cover 2. The outer surface of the edge is in contact with the crimping flange 3, in particular with its second coupling end 33 . the crimping flange 3 encloses the outer surface and is preferably secured thereto by brazing and / or welding.

De manière générale, l'article 1 est un article susceptible d'être soumis à une pression dont une composante exerce une force Ff sur une surface du couvercle opposée à la surface du coin 21 sur laquelle est sertie la partie sertie de l'encoignure 311, cette partie sertie de l'encoignure 311 exerçant alors une force Fe opposée à celle exercée par la composante de la pression.In general, article 1 is an article capable of being subjected to a pressure, one component of which exerts a force F f on a surface of the cover opposite to the surface of the corner 21 on which the crimped part of the corner is crimped. 311, this crimped part of the corner 311 then exerting a force F e opposite to that exerted by the component of the pressure.

Un tel article est par exemple un échangeur de chaleur 1 qui comprend de manière conventionnelle les éléments mentionnés dans l'introduction ci-dessus, dans la partie décrivant l'état de l'art. Ainsi, la bride de sertissage 3 correspond au collecteur, le couvercle 2 à une boite à air (comme sur la figure 7) ou une boite à eau et le cas échéant, le réceptacle 4 au carter du faisceau de l'échangeur de chaleur.Such an article is for example a heat exchanger 1 which conventionally comprises the elements mentioned in the introduction above, in the part describing the state of the art. Thus, the crimping flange 3 corresponds to the manifold, the cover 2 to an air box (as on the figure 7 ) or a water box and, if applicable, the receptacle 4 in the heat exchanger bundle casing.

Un tel échangeur est avantageusement utilisé pour un refroidisseur d'air de suralimentation ou un système de recirculation des gaz d'échappement.Such an exchanger is advantageously used for a charge air cooler or an exhaust gas recirculation system.
