Description

Echangeur de chaleur comprenant un faisceau d'échange thermique inséré dans un boîtier et au moins une boîte collectrice servant à l'admission ou à l'évacuation d'un fluide caloporteur L'invention se rapporte au domaine des échangeurs de chaleur comprenant un faisceau d'échange thermique inséré dans un boîtier et au moins une boîte collectrice servant à l'admission et/ou à l'évacuation d'un fluide caloporteur.  The invention relates to the field of heat exchangers comprising a heat exchange bundle inserted into a housing and at least one manifold for the admission or discharge of a heat transfer fluid. heat exchange inserted into a housing and at least one manifold for the admission and / or discharge of a coolant.
Un échangeur de chaleur, comme par exemple un refroidisseur d'air de suralimentation, comporte généralement un faisceau d'échange thermique comprenant des tubes ou des plaques, à l'intérieur desquels circule un premier fluide caloporteur. Le faisceau d'échange thermique est inséré dans un boîtier comprenant quatres parois. L'échangeur de chaleur comprend également des boîtes collectrices servant à l'entrée et à la sortie d'un second fluide caloporteur. Les boîtes collectrices sont fixées aux parois du boîtier où est inséré le faisceau d'échange thermique de sorte que le second fluide caloporteur puisse échanger de l'énergie calorifique avec le premier fluide caloporteur. A heat exchanger, such as for example a charge air cooler, generally comprises a heat exchange bundle comprising tubes or plates, inside which circulates a first heat transfer fluid. The heat exchange bundle is inserted in a housing comprising four walls. The heat exchanger also comprises collecting boxes for entering and leaving a second heat transfer fluid. The collector boxes are fixed to the walls of the housing where the heat exchange bundle is inserted so that the second heat transfer fluid can exchange heat energy with the first heat transfer fluid.
Lors du procédé de fabrication de l'échangeur de chaleur, les boîtes collectrices sont fixées au boîtier au moyen d'un dispositif de fixation. Le dispositif de fixation actuellement employé en industrie correspond à une lamelle métallique brasée sur la périphérie des parois du boîtier, qui est rabattue par des outils de sertissage par dessus la boîte collectrice et le boîtier afin d'assujettir ces deux éléments ensemble et d'empêcher toute fuite des fluides caloporteurs. In the manufacturing process of the heat exchanger, the manifolds are attached to the housing by means of a fixing device. The fixing device currently used in industry corresponds to a metal strip brazed on the periphery of the walls of the housing, which is folded by crimping tools over the header and the housing in order to fasten these two elements together and prevent any leakage of heat transfer fluids.
Cependant, dans le cas où les boîtes collectrices ont une conformation particulière, il est possible que les outils de sertissage, permettant la fixation de ladite boîte collectrice sur le boîtier contenant le faisceau d'échange thermique, ne puissent atteindre le dispositif de fixation. Il en résulte que le dispositif de fixation ne peut fixer les boîtes collectrices sur l'ensemble du contour du boîtier ce qui compromet l'étanchéité ainsi que la solidité de l'échangeur de chaleur. However, in the case where the manifolds have a particular conformation, it is possible that the crimping tools, allowing the attachment of said manifold on the housing containing the heat exchange bundle, can not reach the fastener. As a result, the fixing device can not fix the manifolds on the entire contour of the housing which compromises the sealing and the strength of the heat exchanger.
Ainsi, un des buts de la présente invention est de remédier au moins partiellement aux inconvénients de l'art antérieur et de proposer un échangeur de chaleur comprenant un dispositif de fixation du et/ou des boîtes collectrices sur le boîtier où est inséré le faisceau d'échange thermique, qui soit apte à fixer la boîte collectrice sur l'ensemble dudit boîtier. La présente invention concerne donc un échangeur de chaleur comprenant un faisceau d'échange thermique inséré dans un boîtier et au moins une boîte collectrice, ledit échangeur comprend un dispositif de fixation de la boîte collectrice sur le boîtier, ledit dispositif de fixation étant une pièce distincte du boîtier et de la boîte collectrice et entourant au moins partiellement ledit boîtier et/ou ladite boîte collectrice. Thus, one of the aims of the present invention is to remedy at least partially the disadvantages of the prior art and to propose a heat exchanger comprising a device for fixing the and / or collector boxes on the housing where is inserted the heat exchange bundle, which is adapted to fix the header on the assembly of said housing. The present invention therefore relates to a heat exchanger comprising a heat exchange bundle inserted in a housing and at least one header, said exchanger comprises a device for fixing the header on the housing, said fastening device being a separate part of the housing and the header and at least partially surrounding said housing and / or said manifold.
La pièce distincte du boîtier et de la boîte collectrice permet au dispositif de fixation d'accéder à des zones auxquels les outils de sertissage n'ont pas normalement accès et de garantir ainsi la fixation de la boîte collectrice sur l'ensemble du contour du boîtier où est inséré le faisceau d'échange thermique. Les boîtes collectrices sont ainsi assujetties et fixées sur l'ensemble du contour du boîtier garantissant l'étanchéité et la solidité de l'échangeur de chaleur. The separate housing and header box allows the fastener to access areas to which crimping tools do not normally have access, thus ensuring that the manifold is secured to the entire housing contour. where is inserted the heat exchange bundle. The collector boxes are thus secured and fixed on the entire contour of the housing ensuring the tightness and strength of the heat exchanger.

L'échangeur de chaleur 1 comprend un faisceau d'échange thermique non représenté autour duquel est disposé un boîtier 2 ici composé de quatre parois 1 3 qui définissent un espace pour guider un premier fluide caloporteur, tel que de l'eau, au sein du faisceau d'échange thermique. Une tubulure d'entrée 15 de fluide et une tubulure de sortie 17 de fluide, ici agencées sur l'une des parois 13, permettent de relier le faisceau d'échange thermique au reste du circuit du fluide caloporteur. L'échangeur de chaleur comprend aussi une boîte collectrice 4 servant à l'admission d'un second fluide caloporteur, ici de l'air de suralimentation, et une boîte collectrice 6 servant à l'évacuation du second fluide caloporteur. Les boîtes collectrices 4 et 6 sont fixées sur les parois 13 du boîtier 2 par un moyen de fixation 8, ici une lamelle sertie sur la paroi 13 du boîtier 2 et sur le pied d'une boîte collectrice 4 et 6. La figure 2 illustre une représentation en perspective partielle d'un échangeur de chaleur 1 , ici un refroidisseur d'air de suralimentation, selon une vue éclatée. Les parois 13 du boîtier 2 comprennent une gorge 1 0 en forme de U qui court sur l'ensemble du pourtour du boîtier 2. La gorge 1 0 est adaptée pour recevoir une extrémité, appelée pied, de la boîte collectrice 6 servant ici à l'évacuation du second fluide caloporteur. Un joint d'étanchéité 12 peut avantageusement être disposé au sein de la gorge 1 0 de manière à être agencé entre la gorge 1 0 du boîtier 2 et la boîte collectrice 6 garantissant ainsi l'étanchéité de l'échangeur de chaleur dans une zone 1 1 dite de contact. L'échangeur de chaleur comprend également une zone de fixation 40, ici réalisé sous la forme d'une excroissance de la paroi 1 3 présentant deux trous, de manière à pouvoir solidariser l'échangeur de chaleur 1 à la structure existante du véhicule. FIG. 1 illustrates a perspective representation of a heat exchanger, here a charge air cooler, according to the invention. The heat exchanger 1 comprises a heat exchange beam not shown around which is disposed a housing 2 here composed of four walls 1 3 which define a space for guiding a first coolant, such as water, within the heat exchange beam. A fluid inlet pipe 15 and a fluid outlet pipe 17, here arranged on one of the walls 13, make it possible to connect the heat exchange bundle to the remainder of the heat transfer fluid circuit. The heat exchanger also comprises a manifold 4 for the admission of a second heat transfer fluid, here of the supercharging air, and a manifold 6 for discharging the second heat transfer fluid. The manifolds 4 and 6 are fixed on the walls 13 of the housing 2 by a fixing means 8, here a lamella crimped on the wall 13 of the housing 2 and on the base of a manifold 4 and 6. FIG. 2 illustrates a partial perspective representation of a heat exchanger 1, here a charge air cooler, according to an exploded view. The walls 13 of the casing 2 comprise a U-shaped groove 10 which runs over the entire periphery of the casing 2. The groove 10 is adapted to receive an end, called a foot, of the manifold 6 used here for the purpose. evacuation of the second heat transfer fluid. A seal 12 may advantageously be arranged in the groove 1 0 so as to be arranged between the groove 1 0 of the housing 2 and the manifold 6 thus ensuring the sealing of the heat exchanger in a zone 1 1 called contact. The heat exchanger also comprises a fixing zone 40, here made in the form of an outgrowth of the wall 1 3 having two holes, so as to be able to join the heat exchanger 1 to the existing structure of the vehicle.
La figure 3 illustre l'échangeur de chaleur de la figure 2 avant la mise en place du dispositif de fixation uniquement pour l'une des deux boîtes collectrices, ici la boîte collectrice 6. Un dispositif de fixation 14 distinct du boîtier 2 et de la boîte collectrice 6 est alors disposé sur l'échangeur de chaleur 1 . FIG. 3 illustrates the heat exchanger of FIG. 2 before setting up the fastening device only for one of the two manifolds, here the manifold 6. An attachment device 14 separate from the case 2 and the manifold 6 is then disposed on the heat exchanger 1.
Le dispositif de fixation 14 peut comprendre par exemple deux pièces 1 6 chacune présentant trois segments 1 8, 20, 22 donnant aux pièces 1 6 la forme d'un U avec deux segments latéraux 1 8, 22 et un segment central 20. Les segments latéraux 1 8 et 22 sont ici destinés à fixer la boîte collectrice 6 sur le boîtier 2 sur la largeur I de l'échangeur de chaleur 1 , tandis que le segment central 20 est représenté ici comme étant destiné à fixer la boîte collectrice 6 sur boîtier 2 sur la longueur L de l'échangeur de chaleur 1 . La conformation de la boîte collectrice 6 ici est telle que le sertissage d'une lamelle est impossible sur une des largueurs I de l'échangeur de chaleur. Afin d'assurer une fixation uniforme du couvercle 6 sur l'ensemble du boîtier 2, les segments latéraux 1 8, 22 du dispositif de fixation 14 sont de type cerclage. Ici, les segments latéraux 1 8, 22 de chaque pièce 1 6 du dispositif de fixation 14 sont glissés sur les largeurs du boîtier 2 et de la boîte collectrice 6 selon les directions respectives indiquées par les flèches sur la figure 3. Les segments 1 8 et 22 sont adaptés aux contours de la boîte collectrice 6 et du boîtier 2. Les pièces 1 6 sont glissées jusqu'à ce que les segments 20 viennent en butée contre les longueurs du boîtier 2 et de la boîte collectrice 6. The fixing device 14 may for example comprise two parts 1 6 each having three segments 1 8, 20, 22 giving the parts 1 6 the shape of a U with two lateral segments 1 8, 22 and a central segment 20. The segments side 1 8 and 22 are here intended to fix the manifold 6 on the housing 2 on the width I of the heat exchanger 1, while the central segment 20 is shown here as being intended to fix the manifold 6 on housing 2 on the length L of the heat exchanger 1. The shape of the manifold 6 here is such that the crimping of a slat is impossible on one of the widths I of the heat exchanger. In order to ensure uniform attachment of the cover 6 to the entire housing 2, the side segments 1 8, 22 of the fixing device 14 are of strapping type. Here, the lateral segments 1 8, 22 of each piece 1 6 of the fixing device 14 are slid over the widths of the housing 2 and the manifold 6 according to the respective directions indicated by the arrows in FIG. and 22 are adapted to the contours of the manifold 6 and the housing 2. The parts 1 6 are slid until the segments 20 abut against the lengths of the housing 2 and the manifold 6.
Le segment 20 est réalisé sous la forme d'une bande métallique et vient en butée contre le boîtier 2 et la boîte collectrice 6. Le segment 20 peut alors être serti sur l'échangeur de chaleur 1 . The segment 20 is made in the form of a metal strip and abuts against the housing 2 and the manifold 6. The segment 20 can then be crimped on the heat exchanger 1.
Il est à noter que, le dispositif de fixation 14 présente une zone de transition 14, réalisée sous la forme d'un coin, reliant les segments latéraux 18 ou 22 au segment central 20. Ces coins 24 présentent une conformation particulière avec un bord arrondi permettant la transition d'un segment de type bande (segment 20) à un segment de type cerclage (segment 18, 22) tout en étant adapté aux contours de l'échangeur de chaleur. La figure 4 illustre l'échangeur de chaleur de la figure 2 après la mise en place du dispositif de fixation 14. Après l'introduction du dispositif de fixation 14, les parois centrales 20 sont serties afin de garantir l'étanchéité de l'échangeur de chaleur 1 . Les segments 20, selon un mode de réalisation non représenté, peuvent être de type bande métallique entièrement plate de manière à ce que les outils de sertissage déforment la bande au niveau de la zone de contact 1 1 c'est-à-dire pardessus la gorge 10 du boîtier 2 et pardessus le pied de la boîte collectrice 6. It should be noted that, the fixing device 14 has a transition zone 14, made in the form of a wedge, connecting the lateral segments 18 or 22 to the central segment 20. These corners 24 have a particular conformation with a rounded edge allowing the transition from a band-type segment (segment 20) to a strapping-type segment (segment 18, 22) while being adapted to the contours of the heat exchanger. FIG. 4 illustrates the heat exchanger of FIG. 2 after the fixing device 14 has been put in place. After the introduction of the fixing device 14, the central walls 20 are crimped in order to guarantee the tightness of the exchanger. heat 1. The segments 20, according to an embodiment not shown, can be of completely flat metal strip type so that the crimping tools deform the strip at the contact zone 1 1 that is to say above the groove 10 of the housing 2 and over the foot of the manifold 6.
Selon le mode de réalisation représenté à la figure 3, le segment 20 est une bande métallique avec une première extrémité plate 39 et l'autre extrémité repliée 41 en direction de l'échangeur de chaleur au regard de la direction de glissement indiquée par la flèche. L'extrémité plate 39 est disposée pour entrer en butée contre la gorge 10 du boîtier 2 tandis que l'extrémité repliée 41 est agencée pour entrer en butée contre la paroi 13 du boîtier 2 lors de l'insertion du dispositif de fixation 14. Seule l'extrémité plate 39 sera déformée lors du sertissage pour être ramenée pardessus le pied de la boîte collectrice 6 de manière à assujettir la boîte collectrice 6 au boîtier 2. According to the embodiment shown in Figure 3, the segment 20 is a metal strip with a first flat end 39 and the other end folded 41 towards the heat exchanger with respect to the sliding direction indicated by the arrow . The flat end 39 is disposed to abut against the groove 10 of the housing 2 while the folded end 41 is arranged to abut against the wall 13 of the housing 2 during the insertion of the fixing device 14. Only the flat end 39 will be deformed during crimping to be brought over the foot of the manifold 6 so as to secure the manifold 6 to the housing 2.
La figure 5 est une vue plus en détail de la zone de contact 1 1 . La gorge 10 est en forme de U et adaptée à recevoir un pied de la boîte collectrice 6. En outre, un joint d'étanchéité 1 2 peut être agencé entre le fond de la gorge 1 0 et le pied de la boîte collectrice 6. La gorge 1 0 court sur tout le pourtour du boîtier 2 afin de garantir l'étanchéité de l'échangeur de chaleur 1 . Les segments 1 8 et 22 de type cerclage présentent trois parois, une base 23 venant ici perpendiculairement au contact de la paroi 1 3 du boîtier 2, une paroi latérale 25 perpendiculaire à la base 23 et un rebord 27 orienté vers l'intérieur du cerclage en direction du boîtier 2. La paroi latérale 25 et le rebord 27 du cerclage définissent un angle a inférieur ou égale à 90°. Les segments 1 8, 22 fixe nt le pied de la boîte collectrice 6 au sein de la zone de contact 1 1 sur le boîtier 2 en exerçant une pression sur ces éléments afin de maintenir l'échangeur de chaleur 1 assemblé. Figure 5 is a more detailed view of the contact area January 1. The groove 10 is U-shaped and adapted to receive a foot of the manifold 6. In addition, a seal 1 2 sealing can be arranged between the bottom of the groove 1 0 and the base of the manifold 6. The groove 1 0 short all around the housing 2 to ensure the sealing of the heat exchanger 1 . The ring-type segments 18 and 22 have three walls, a base 23 coming here perpendicular to the contact of the wall 1 3 of the casing 2, a side wall 25 perpendicular to the base 23 and a flange 27 facing towards the inside of the strapping. towards the housing 2. The side wall 25 and the rim 27 of the strapping define an angle a less than or equal to 90 °. The segments 1 8, 22 fixed the foot of the manifold 6 within the contact area January 1 on the housing 2 by exerting pressure on these elements to maintain the heat exchanger 1 assembled.
Les segments 1 8 et 22 présentent des zones rigides ou peu déformable sur au moins un des côtés du dispositif de fixation 14. Il est plus avantageux que la zone rigide soit agencée du côté de l'échangeur de chaleur où les outils de sertissage n'ont pas accès au dispositif de fixation. The segments 1 8 and 22 have rigid areas or little deformable on at least one side of the fixing device 14. It is more advantageous that the rigid zone is arranged on the side of the heat exchanger where the crimping tools n ' have no access to the fixture.
Les figures 6 et 7 illustrent un échangeur de chaleur 1 avec un dispositif de réalisation selon un deuxième mode de réalisation. Ici, le dispositif de fixation 14 est réalisé en une seule pièce 30 avec deux demi-pièces 43 assemblées par une zone charnière 32. Chaque demi-pièce 43 comprend les mêmes segments que vu précédemment avec les segments 45 et 47 de type cerclage adaptés pour la largeur de l'échangeur de chaleur, et les segments 49 de type bande métallique adaptés pour la longueur de l'échangeur de chaleur, avec la zone charnière 32 reliant par exemple les deux segments 47. Figures 6 and 7 illustrate a heat exchanger 1 with an embodiment according to a second embodiment. Here, the fixing device 14 is made in one piece 30 with two half-pieces 43 assembled by a hinge zone 32. Each half-piece 43 comprises the same segments as previously seen with the segments 45 and 47 of strapping type adapted to the width of the heat exchanger, and the metal band segments 49 adapted for the length of the heat exchanger, with the hinge zone 32 connecting for example the two segments 47.
La boîte collectrice 6 est introduite sur le boîtier 2 au niveau de la zone de contact 1 1 . Le dispositif de fixation 14 est alors refermé en reliant les deux segments 45 ensemble par un mouvement de pivotement de la zone charnière 32. Les segments 49 sont ensuite sertis sur le boîtier 2 et sur le pied de la boîte collectrice 6 afin de garantir la fermeture du dispositif de fixation. The manifold 6 is introduced on the housing 2 at the contact zone January 1. The fixing device 14 is then closed by connecting the two segments 45 together by a pivoting movement of the hinge zone 32. The segments 49 are then crimped on the housing 2 and on the base of the manifold 6 in order to guarantee the closure of the fixing device.
Un autre moyen de fermeture complémentaire au sertissage des segments 20 est de solidariser les deux segments 45 par une soudure 34 comme illustrée à la figure 7. La soudure 34 peut par exemple être une soudure de type TIG (pour l'anglais Tungsten Inert Gas) ou une soudure par points. Cette soudure 34 est compatible avec les deux modes de réalisation illustrés aux figures 1 à 7. On peut voir sur la figure 6 que l'échangeur de chaleur 1 présente une largeur avec un bord droit 38 et l'autre largeur avec un bord arrondi 36. Le dispositif de fixation, ayant une forme complémentaire au boîtier 2 et à la boîte collectrice 6, présente les segments latéraux 22 reliés par la charnière 32 adaptés aux bords droits 38 et les segments latéraux 1 8 adaptés aux bords arrondis 36. La conformation arrondie facilite le glissement des cerclages tout du long de la largeur de l'échangeur de chaleur et est plus adapté pour un mouvement de pivotement qu'un mouvement de glissement, la forme arrondie étant le résultat du mouvement de rotation autour de la charnière 32. Bien entendu l'invention ne se limite pas au positionnement et à l'agencement des parois de type bande et de type cerclage. Le dispositif de fixation 14 ne se limite pas qu'à la boîte collectrice 6 servant à l'évacuation du second fluide caloporteur mais peut être utilisé pour fixer la boîte collectrice 4, servant à l'admission du second fluide caloporteur, au boîtier 2. Selon un mode de réalisation non illustré, si la boîte collectrice 6 est dans une conformation où les outils de sertissage n'ont pas accès à plusieurs côtés, il est envisageable d'agencer des segments de type cerclage sur plusieurs côtés que ce soit dans la largeur et/ou dans la longueur. Il est aussi possible d'envisager selon un mode non représenté des segments avec des parties de type cerclage et des parties de type bande avec des zones de transition adaptées entre les deux parties. Il est aussi envisageable d'utiliser d'autre moyens pour fixer les zones non rigides à l'échangeur de chaleur comme par exemples des agrafes ou des dents. Another means of closing complementary crimping segments 20 is to secure the two segments 45 by a weld 34 as shown in Figure 7. The weld 34 may for example be a type of welding TIG (Tungsten Inert Gas) or spot welding. This weld 34 is compatible with both embodiments illustrated in Figures 1 to 7. It can be seen in Figure 6 that the heat exchanger 1 has a width with a straight edge 38 and the other width with a rounded edge 36 The fixing device, having a shape complementary to the housing 2 and to the manifold 6, has the lateral segments 22 connected by the hinge 32 adapted to the straight edges 38 and the lateral segments 1 8 adapted to the rounded edges 36. The rounded conformation facilitates the sliding of the straps all along the width of the heat exchanger and is more suitable for a pivoting movement than a sliding movement, the rounded shape being the result of the rotational movement around the hinge 32. Well It is understood that the invention is not limited to the positioning and arrangement of strip-type and strapping-type walls. The fastening device 14 is not limited only to the manifold 6 used for the evacuation of the second heat transfer fluid but can be used to fix the manifold 4 for the admission of the second heat transfer fluid to the housing 2. According to a non-illustrated embodiment, if the manifold 6 is in a conformation where the crimping tools do not have access to several sides, it is conceivable to arrange strapping-type segments on several sides whether in the width and / or in length. It is also possible to envisage, in a mode that is not represented, segments with strapping-type portions and band-like portions with transition zones adapted between the two parts. It is also conceivable to use other means for fixing the non-rigid areas to the heat exchanger, for example staples or teeth.
L'invention ne se limite pas non plus à la nature de l'échangeur de chaleur 1 . L'échangeur de chaleur peut être un refroidisseur d'air de suralimentation ou WCAC (de l'anglais Watercooled Charge Air Coolers), ou un condenseur ou tout autre échangeur thermique. Il doit être bien entendu toutefois que ces exemples de réalisation sont donnés à titre d'illustration de l'objet de l'invention. L'invention n'est pas limitée à ces modes de réalisation décrits précédemment et fournis uniquement à titre d'exemple. Elle englobe diverses modifications, formes alternatives et autres variantes que pourra envisager l'homme du métier dans le cadre de la présente invention et notamment toutes combinaison des différents modes de réalisation décrits précédemment. The invention is not limited to the nature of the heat exchanger 1. The heat exchanger may be a charge air cooler or WCAC (English Watercooled Charge Air Coolers), or a condenser or other heat exchanger. It should be understood, however, that these exemplary embodiments are given by way of illustration of the object of the invention. The invention is not limited to these embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that may be considered by those skilled in the art within the scope of the present invention and in particular any combination of the various embodiments described above.
