Description

L'invention concerne les boîtes collectrices pour les échangeurs de chaleur.The invention relates to manifolds for heat exchangers.

De nombreux échangeurs de chaleur du type radiateur de chauffage ou de refroidissement ainsi que les refroidisseurs d'air de suralimentation sont construits avec une boîte collectrice qui comprend une plaque collectrice métallique surmontée d'un couvercle en plastique.Many heat exchangers of the heating or cooling radiator type as well as the charge air coolers are constructed with a manifold which includes a metallic manifold plate surmounted by a plastic cover.

Dans ces échangeurs, le couvercle est maintenu contre la plaque collectrice par des pattes de celle-ci qui sont rabattues au-dessus d'un pied du couvercle, un joint étant disposé entre le pied du couvercle et la plaque collectrice pour assurer l'étanchéité de la boîte collectrice.In these exchangers, the cover is held against the collector plate by lugs thereof which are folded over a foot of the cover, a seal being disposed between the base of the cover and the collector plate to ensure sealing of the manifold.

Lorsque ces échangeurs sont utilisés dans des véhicules automobiles, la pression à l'intérieur de la boîte exerce une contrainte sur le couvercle et la plaque collectrice. En réaction, la plaque collectrice a tendance à se déformer jusqu'à la rupture de la boîte collectrice.When these exchangers are used in motor vehicles, the pressure inside the box exerts a stress on the cover and the collector plate. In reaction, the collector plate tends to deform until the collector box ruptures.

De nombreuses solutions ont été proposées pour traiter ce problème, notamment par l'ajout de nervures pour renforcer la plaque collectrice. Cependant, ces solutions ne sont pas satisfaisantes.Many solutions have been proposed to deal with this problem, in particular by adding ribs to reinforce the collector plate. However, these solutions are not satisfactory.

L'invention vient améliorer la situation.The invention improves the situation.

À cet effet, l'invention propose une boîte collectrice, comprenant les caractéristiques de la revendication 1.To this end, the invention provides a manifold, comprising the features of claim 1.

Un échangeur de chaleur équipé d'une telle plaque collectrice est particulièrement avantageux car il permet des résultats excellents en termes de résistance à la pression de fonctionnement.A heat exchanger equipped with such a header plate is particularly advantageous because it allows excellent results in terms of resistance to operating pressure.

Selon différents modes de réalisation :

  • les nervures présentent un bord, dit interne, et la tangente passant par le milieu du bord interne de chaque nervure présente un angle compris entre 30° et 60° avec le fond de la plaque,

  • the bottom of said plate is flat and said plate is provided without a groove.

Par bord interne, on entend le bord de la nervure tournée vers l'intérieur de la boîte, c'est-à-dire le bord de la nervure la plus proche de l'extrémité du bord relevé opposée à celle reliée audit fond.By internal edge is meant the edge of the rib facing the inside of the box, that is to say the edge of the rib closest to the end of the raised edge opposite to that connected to said bottom.

Selon différents modes de réalisation :

  • ledit joint présente une section ronde lorsqu'il est non comprimé,
  • chaque nervure est éloignée des ouvertures de la plaque d'une distance (L) supérieure ou égale à deux tiers de la dimension latérale du joint, lorsqu'il est non comprimé.
According to different embodiments:
  • said seal has a round section when it is uncompressed,
  • each rib is spaced from the openings of the plate by a distance (L) greater than or equal to two thirds of the lateral dimension of the joint, when it is uncompressed.

L'invention concerne encore un échangeur de chaleur comprenant un faisceau de tubes dont les extrémités sont reçues dans les ouvertures de boîtes collectrices telles que définies plus haut.The invention also relates to a heat exchanger comprising a bundle of tubes, the ends of which are received in the openings of manifolds as defined above.

Les dessins et la description ci-après contiennent, pour l'essentiel, des éléments de caractère certain. Ils pourront donc non seulement servir à mieux faire comprendre la présente invention, mais aussi contribuer à sa définition, le cas échéant.The drawings and the description below essentially contain elements of a certain nature. They can therefore not only serve to better understand the present invention, but also contribute to its definition, if necessary.

La figure 1 représente un échangeur de chaleur 2 selon l'invention. L'échangeur de chaleur 2 comprend deux boîtes collectrices 4 et 6 qui reçoivent dans des ouvertures qu'elles comportent un faisceau 8 de tubes 10.The figure 1 represents a heat exchanger 2 according to the invention. The heat exchanger 2 comprises two manifolds 4 and 6 which receive in openings that they comprise a bundle 8 of tubes 10.

La boîte collectrice 4 présente une entrée de fluide 12 à partir de laquelle le fluide circule dans le faisceau 8 de tubes 10, entre les boîtes collectrices 4 et 6, jusqu'à une sortie de fluide 14 de la boîte collectrice 4.The manifold 4 has a fluid inlet 12 from which the fluid circulates in the bundle 8 of tubes 10, between the manifolds 4 and 6, up to a fluid outlet 14 from the manifold 4.

D'autres réalisations sont possibles pour l'échangeur de chaleur 2, par exemple l'utilisation d'une seule boîte collectrice, ou une répartition différente de l'entrée de fluide 12 et de la sortie de fluide 14.Other embodiments are possible for the heat exchanger 2, for example the use of a single manifold, or a different distribution of the fluid inlet 12 and the fluid outlet 14.

Comme on peut le voir sur cette figure, les boîtes collectrices 4 et 6 sont réalisées de manière similaire, c'est-à-dire avec un couvercle 16 qui vient recouvrir une plaque collectrice 18.As can be seen in this figure, the manifolds 4 and 6 are produced in a similar manner, that is to say with a cover 16 which covers a manifold plate 18.

Le couvercle 16 a une forme convexe et délimite avec la plaque 18 un réservoir de fluide pour la boîte collectrice. La plaque 18 est sensiblement plate et comporte des ouvertures 17 de réception des tubes 10 du faisceau 8.The cover 16 has a convex shape and defines with the plate 18 a fluid reservoir for the manifold. The plate 18 is substantially flat and has openings 17 for receiving the tubes 10 of the bundle 8.

Le couvercle 16 présente un rebord périphérique 19 dans sa partie inférieure qui vient en contact avec la plaque 18, par l'intermédiaire d'un joint 34, pour fermer la boîte collectrice. Le rebord périphérique 19 forme un pied qui est reçu au niveau de la plaque 18 et maintenu en place une fois la boîte collectrice fermée comme cela apparaîtra dans ce qui suit.The cover 16 has a peripheral flange 19 in its lower part which comes into contact with the plate 18, by means of a seal 34, to close the manifold. The peripheral rim 19 forms a foot which is received at the level of the plate 18 and held in place once the collector box closed as will appear in the following.

Dans l'exemple décrit ici, le couvercle 16 est réalisé en plastique ou en métal, par exemple en aluminium ou en alliage d'aluminium, et la plaque collectrice 18 est réalisée en métal, par exemple en aluminium, en alliage d'aluminium ou en acier ou en alliage d'acier.In the example described here, the cover 16 is made of plastic or metal, for example aluminum or aluminum alloy, and the collector plate 18 is made made of metal, for example aluminum, aluminum alloy or steel or steel alloy.

Comme on peut le voir sur la figure 2 et suivantes, la plaque collectrice 18 présente un rebord périphérique 20 qui sert d'une part à recevoir le couvercle 16, et d'autre part à sertir celui-ci une fois qu'il est reçu. Pour cela, le rebord périphérique 20 comprend une portion de réception 22 et une portion de maintien 24.As we can see on the figure 2 and following, the collector plate 18 has a peripheral rim 20 which serves on the one hand to receive the cover 16, and on the other hand to crimp the latter once it is received. For this, the peripheral rim 20 includes a receiving portion 22 and a holding portion 24.

Le joint 34 est prévu entre le pied 19 du couvercle 16 et le fond 32 de la portion de réception 22 de la plaque 18.The seal 34 is provided between the base 19 of the cover 16 and the bottom 32 of the receiving portion 22 of the plate 18.

Dans l'exemple décrit ici, la plaque collectrice 18 est plane et/ou réalisée sans gorge, c'est-à-dire que le fond 40 de la plaque collectrice est plat et le pied 19 du couvercle vient en appui latéralement contre les extrémités des tubes. La portion de réception 22 présente donc en conséquence une forme générale sensiblement en "L". Autrement dit le plan d'appui du joint contre la plaque, c'est-à-dire le fond 32 de la portion de réception 22, est confondu avec le plan des ouvertures 17 de passage des tubes.In the example described here, the collector plate 18 is flat and / or produced without a groove, that is to say that the bottom 40 of the collector plate is flat and the foot 19 of the cover bears laterally against the ends tubes. The receiving portion 22 therefore has therefore a generally substantially "L" shape. In other words, the support plane of the seal against the plate, that is to say the bottom 32 of the receiving portion 22, coincides with the plane of the openings 17 for passage of the tubes.

Ladite plaque collectrice plane pourra être munie de collets 23 au niveau des ouvertures 17 pour le passage des tubes. Lesdits collets sont orientés vers l'intérieur, comme illustré à la figure 2, ou l'extérieur de la boîte. Ils entourent les tubes et facilitent l'insertion et/ou le brasage des tubes sur la plaque collectrice. Dans un tel cas de figure, c'est-à-dire dans le cas d'une plaque plane avec collets, lesdits collets 23 s'étendent depuis le plan d'appui du joint contre la plaque et le pied du couvercle prend latéralement appui soit contre les collets, pour des collets orientés vers l'intérieur de la boîte, soit contre les tubes, pour des collets orientés vers l'extérieur de la boîte.Said flat collecting plate may be provided with collars 23 at the openings 17 for the passage of the tubes. Said collars are oriented inwards, as illustrated in the figure 2 , or the outside of the box. They surround the tubes and facilitate the insertion and / or brazing of the tubes on the collector plate. In such a case, that is to say in the case of a flat plate with collars, said collars 23 extend from the bearing plane of the seal against the plate and the foot of the cover takes lateral support. either against the collars, for collars oriented towards the inside of the box, or against the tubes, for collars oriented towards the outside of the box.

Dans d'autres modes de réalisation, la plaque collectrice 18 peut être réalisée avec une gorge, prévue à la périphérie du fond de plaque collectrice, pour le logement du joint. Dans ce cas, la portion de réception présente une forme générale sensiblement en "U".In other embodiments, the manifold plate 18 can be made with a groove, provided at the periphery of the bottom of the manifold plate, for housing the seal. In this case, the receiving portion has a general shape substantially in a "U" shape.

Dans l'exemple décrit ici, la portion de maintien 24 est réalisée au moyen d'une pluralité de dents 26 qui sont réalisées dans le prolongement de la branche relevé 21 du L de la portion de réception 22, et qui sont séparées les unes des autres par des évidements 28. En variante, les dents 26 pourraient être reliées pour former un bord.In the example described here, the holding portion 24 is produced by means of a plurality of teeth 26 which are produced in the extension of the raised branch 21 of the L of the receiving portion 22, and which are separated from one another others by recesses 28. Alternatively, the teeth 26 could be connected to form an edge.

Lorsque la boîte collectrice 4 est fermée, les dents 26 sont rabattues sur le pied 19 qui est reçu dans la portion de réception 22, comme cela apparaît mieux sur la figure 4, ce qui réalise un sertissage de couvercle 16 sur la plaque 18.When the manifold 4 is closed, the teeth 26 are folded down on the foot 19 which is received in the receiving portion 22, as appears better on the figure 4 , which achieves a cover crimp 16 on the plate 18.

Comme on peut le voir sur la figure 2, la portion de réception 22 comporte une pluralité de nervures de renforcement 30 qui sont réalisées régulièrement le long de la portion de réception 22, entre les ouvertures pour les tubes 10 dans l'exemple décrit ici.As we can see on the figure 2 , the receiving portion 22 comprises a plurality of reinforcing ribs 30 which are produced regularly along the receiving portion 22, between the openings for the tubes 10 in the example described here.

En variante, les nervures 30 pourraient être réalisées de manière non régulière, et/ou en face des ouvertures pour les tubes 10 et/ou à un pas différent de celui des tubes.Alternatively, the ribs 30 could be produced in an irregular manner, and / or opposite the openings for the tubes 10 and / or at a different pitch from that of the tubes.

La réalisation des nervures 30 apparaît mieux sur la figure 3.The production of the ribs 30 appears better on the figure 3 .

Comme on peut le voir sur cette figure, les nervures 30 sont formées dans une partie incurvée 31 de la portion de réception 22, et s'étendent de manière sensiblement symétrique sur les deux branches du L de la portion de réception 22, en saillant vers l'intérieur de celle-ci.As can be seen in this figure, the ribs 30 are formed in a curved part 31 of the receiving portion 22, and extend substantially symmetrically on the two branches of the L of the receiving portion 22, projecting towards inside of it.

Les nervures 30 sont réalisées par emboutissage avec formation d'une nervure à bord droit. Cela permet d'augmenter la résistance des nervures à l'effort en utilisation.The ribs 30 are produced by stamping with the formation of a rib with a straight edge. This increases the resistance of the ribs to the effort in use.

L'emboutissage est réalisé de telle sorte que le bord interne de la nervure forme un angle de 45° avec le fond 32 de la portion de réception 22. En variante, cet angle est compris entre 30° et 60°.The stamping is carried out so that the internal edge of the rib forms an angle of 45 ° with the bottom 32 of the receiving portion 22. As a variant, this angle is between 30 ° and 60 °.

La figure 4 vient compléter la figure 3 pour montrer l'intérêt des nervures particulières de l'invention.The figure 4 completes the figure 3 to show the interest of the particular ribs of the invention.

En effet, les nervures des solutions antérieures présentent des dimensions très importantes, qui viennent augmenter la taille de la boîte collectrice et donc l'encombrement de l'échangeur de chaleur 2, ce qui est particulièrement gênant dans les véhicules automobiles modernes.Indeed, the ribs of the previous solutions have very large dimensions, which increase the size of the manifold and therefore the size of the heat exchanger 2, which is particularly troublesome in modern motor vehicles.

Le Demanderesse a établi que les dimensions de la boîte collectrice peuvent être réduites sans sacrifier la fiabilité de l'échangeur 2 lorsque les nervures 30 sont réalisées d'une manière spécifique.The Applicant has established that the dimensions of the manifold can be reduced without sacrificing the reliability of the exchanger 2 when the ribs 30 are produced in a specific manner.

Pour cela, l'encombrement des nervures 30 est contrôlé. Afin de réduire de manière optimale les dimensions de la boîte collectrice, les nervures 30 sont réalisées avec une hauteur H.For this, the size of the ribs 30 is controlled. In order to optimally reduce the dimensions of the manifold, the ribs 30 are produced with a height H.

La hauteur H est prévue pour être inférieure à la distance entre la partie du pied 19 qui est la plus proche du fond 32 et la paroi de réception 22. Cette hauteur H est donc inférieure à la hauteur du joint 34 compressé lorsque la boîte collectrice est fermée.The height H is intended to be less than the distance between the part of the leg 19 which is closest to the bottom 32 and the receiving wall 22. This height H is therefore less than the height of the compressed joint 34 when the manifold is closed.

Dans l'exemple décrit ici la hauteur H est de 2 mm. Dans les échangeurs de chaleurs visés par l'invention, la hauteur H est généralement comprise entre 1 mm et 5 mm.In the example described here, the height H is 2 mm. In the heat exchangers targeted by the invention, the height H is generally between 1 mm and 5 mm.

Ainsi, les nervures 30 sont réalisées "sous" le pied 19, et il n'est donc plus nécessaire de dégager un volume latéral pour les contenir.Thus, the ribs 30 are made "under" the foot 19, and it is therefore no longer necessary to release a lateral volume to contain them.

Cela est notamment possible grâce à la déformation du joint 34 localement sur chacune des nervures 30.This is in particular possible thanks to the deformation of the seal 34 locally on each of the ribs 30.

Dès lors, le joint 34 n'est plus totalement agencé linéairement le long du fond 32 de la paroi de réception 22, mais forme une sorte de serpentin qui épouse les nervures 30. Pour garantir la bonne étanchéité de la boîte collectrice dans ces conditions, les nervures 30 sont réalisées de sorte qu'elles s'étendent jusqu'à une distance L par rapport à l'extrémité des ouvertures pour les tubes 10.Consequently, the seal 34 is no longer completely arranged linearly along the bottom 32 of the receiving wall 22, but forms a sort of serpentine which follows the ribs 30. To guarantee the proper tightness of the manifold under these conditions, the ribs 30 are made so that they extend up to a distance L from the end of the openings for the tubes 10.

Il apparaît donc avantageux dans cette configuration de disposer les nervures 30 entre les ouvertures des tubes 10, comme cela a été décrit plus haut. Dans ce cas, les nervures sont espacées avec un pas qui est le même que celui des tubes, c'est-à-dire entre 5 mm et 10 mm, et préférablement entre 6 mm et 8 mm.It therefore appears advantageous in this configuration to arrange the ribs 30 between the openings of the tubes 10, as has been described above. In this case, the ribs are spaced with a pitch which is the same as that of the tubes, that is to say between 5 mm and 10 mm, and preferably between 6 mm and 8 mm.

En tout état de cause, la Demanderesse a établit que la distance L doit être supérieure à la moitié de la valeur d'une dimension latérale du joint 34, et de manière préférée supérieure à deux tiers de cette valeur.In any event, the Applicant has established that the distance L must be greater than half the value of a lateral dimension of the joint 34, and preferably greater than two thirds of this value.

Dans le cas où le joint 34 est un joint cylindrique, alors la dimension latérale est le diamètre du joint 34. Dans le cas où le joint 34 n'est pas cylindrique, c'est sa largeur qui est prise en compte.In the case where the joint 34 is a cylindrical joint, then the lateral dimension is the diameter of the joint 34. In the case where the joint 34 is not cylindrical, it is its width which is taken into account.

On notera que la dimension du joint 34 est entendue à l'état initial du joint 34, c'est-à-dire avant sa compression suite à la fermeture de la boîte collectrice.It will be noted that the dimension of the seal 34 is understood in the initial state of the seal 34, that is to say before its compression following the closing of the manifold.

Sur la figure 5, on a représenté une boîte collectrice en variante, dans laquelle les nervures 30 ne sont pas réalisées à bords droits, mais à bords incurvés. Les bords sont alors sensiblement en forme de calotte sphérique. Cela permet de simplifier l'opération d'emboutissage.On the figure 5 , there is shown a variant manifold, in which the ribs 30 are not made with straight edges, but with curved edges. The edges are then substantially in the form of a spherical cap. This simplifies the stamping operation.

Ici encore, les nervures 30 sont réalisées de sorte que la tangente au milieu du bord interne de la nervure 30 soit de 45°. De manière préférée, cet angle est compris entre 30° et 60°.Here again, the ribs 30 are produced so that the tangent in the middle of the internal edge of the rib 30 is 45 °. Preferably, this angle is between 30 ° and 60 °.

La présente invention a été décrite en référence à des modes de réalisations particuliers. Cependant, il va de soi que les caractéristiques décrites en rapport à un mode de réalisation particulier peuvent être transposées à un autre mode et que dans une variante de réalisation, la plaque comporte des nervures à bords droits et des nervures à bords convexes ou en calotte sphérique.The present invention has been described with reference to particular embodiments. However, it goes without saying that the characteristics described in relation to a particular embodiment can be transposed to another mode and that in a variant embodiment, the plate has ribs with straight edges and ribs with convex edges or in a spherical cap.

En outre, la présente invention a été décrite en rapport à des boîtes collectrices sans gorge, et à des échangeurs de chaleur assemblés par brasage. Cependant, elle est directement applicable à des échangeurs de chaleur comprenant des boîtes collectrices à gorge et/ou assemblés mécaniquement.In addition, the present invention has been described in relation to manifolds without grooves, and to heat exchangers assembled by brazing. However, it is directly applicable to heat exchangers comprising grooved manifold boxes and / or mechanically assembled.

Dans le cas d'échangeurs dont la ou les boîtes comprennent une plaque collectrice munie d'une gorge, les nervures conformes à l'invention seront prévues entre le bord externe de la gorge et le fond de celle-ci.In the case of exchangers in which the box or boxes comprise a collecting plate provided with a groove, the ribs according to the invention will be provided between the external edge of the groove and the bottom of the latter.
