Abstract

Echangeur de chaleur comportant des tubes 1 débouchant dans des plaques collectrices 3 délimitant un rebord pérpiphérique 4 pour un joint d'étanchéité 9 contre lequel est appliqué le rebord 7 d'une boîte à eau 6 au moyen de pattes repliées 13 et par l'intermédiaire d'une barrette 10.Heat exchanger comprising tubes 1 opening into collecting plates 3 delimiting a peripheral edge 4 for a seal 9 against which the edge 7 of a water box 6 is applied by means of folded tabs 13 and by means of a bar 10.

Description

La présente invention concerne les échangeurs de chaleur comportant un faisceau de tubes engagé dans des plaques collectrices qui sont destinées à être recou- vertes par des boîtes à eau assemblées de façon démontable, c'est-à-dire fixées sur la périphérie de chaque plaque collectrice avec interposition d'un joint déformable.The present invention relates to heat exchangers comprising a bundle of tubes engaged in header plates which are intended to be covered by water boxes assembled in a removable manner, that is to say fixed on the periphery of each plate. collector with interposition of a deformable joint.

Jusqu'à présent, dans ce type d'échangeurs de chaleur, on est amené à réaliser les boites à eau en matière synthétique moulée de façon qu'elles présentent, à leur partie inférieure, un talon ou rebord épais et saillant sur lequel sont serties des pattes ou saillies formées soit par la plaque collectrice elle-même, soit par une pince rapportée.Up to now, in this type of heat exchangers, it has been necessary to produce water boxes of molded synthetic material so that they have, at their lower part, a thick and protruding heel or rim on which are crimped. tabs or projections formed either by the collecting plate itself, or by an attached clamp.

Il n'était cependant pas possible d'utiliser la même technique en mettant en oeuvre des boites à eau métalliques, car ces boîtes présentent nécessairement une faible épaisseur de parois et, par conséquent, il n'est pas possible de former, de façon économique, un talon épais permettant un sertissage efficace.However, it was not possible to use the same technique when using metal water boxes, because these boxes necessarily have a small wall thickness and, therefore, it is not possible to form economically , a thick heel allowing effective crimping.

Pour tenter d'apporter une solution à ce problème, le brevet britannique 699.032 a décrit des réalisations dans lesquelles le bord périphérique de la boite à eau est serti sur un joint souple en formant une nervure creuse qui est destinée à augmenter la rigidité du bord serti. Cette disposition apparemment satisfaisante nécessite la mise en oeuvre d'un outillage complexe pour former la nervure creuse à l'intérieur de laquelle est placé le joint souple.In an attempt to provide a solution to this problem, British patent 699,032 has described embodiments in which the peripheral edge of the water box is crimped onto a flexible joint by forming a hollow rib which is intended to increase the rigidity of the crimped edge. . This apparently satisfactory arrangement requires the implementation of a complex tool to form the hollow rib inside which is placed the flexible joint.

La Demanderesse a elle-même décrit dans son brevet français 74 16284 une réalisation dans laquelle le bord périphérique de la boîte à eau présente une conformation arrondie pour augmenter sa rigidité et, dans ce cas, le bord de la plaque collectrice est serti sur l'extrémité relevée du bord périphérique de la boite à eau.The Applicant has itself described in its French patent 74 16284 an embodiment in which the peripheral edge of the water box has a rounded conformation to increase its rigidity and, in this case, the edge of the collector plate is crimped on the raised end of the peripheral edge of the water box.

Des difficultés sont apparues dans la réalisation pratique car les dispositifs de sertissage des pattes de la plaque collectrice à l'intérieur de la partie courbe du bord périphérique de la boîte à eau ont souvent pour effet de déformer ce bord périphérique et, par conséquent, de gauchir la partie du bord périphérique qui prend normalement appui sur le joint souple d'étanchéité.Difficulties have arisen in practical implementation since the devices for crimping the tabs of the collector plate inside the curved part of the peripheral edge of the water box often have the effect of deforming this peripheral edge and, consequently, of warp the part of the peripheral edge which normally rests on the flexible seal.

Conformément à l'invention, l'échangeur de chaleur comportant un faisceau de tubes débouchant dans des plaques collectrices délimitant, à leur périphérie, une gorge bordée extérieurement par un bord montant, un joint d'étanchéité étant disposé dans le fond de la gorge pour être serré par le dessous d'un rebord que forme une boîte à eau maintenue soit par des parties de sertissage prolongeant le bord montant de la plaque collectrice, soit par une pince rapportée est caractérisé en ce que la boîte à eau est à paroi mince et en ce qu'une barrette est interposée entre le dessus du rebord de cette boîte à eau et les parties de sertissage de la plaque collectrice ou de la pince rapportée.According to the invention, the heat exchanger comprising a bundle of tubes opening into collector plates delimiting, at their periphery, a groove externally bordered by a rising edge, a seal being arranged in the bottom of the groove for be clamped by the underside of a rim formed by a water box maintained either by crimping parts extending the rising edge of the collecting plate, or by an attached pliers is characterized in that the water box is thin-walled and in that a bar is interposed between the top of the edge of this water box and the crimping parts of the collector plate or of the attached pliers.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemplesnon limitatifs, au dessin annexé.Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.

La fig. 6 est une coupe vue suivant la ligne VI-VI de la fig. 5.Fig. 6 is a section taken along line VI-VI of FIG. 5.

Au dessin, 1 désigne les tubes de circulation d'un échangeur de chaleur, notamment d'un échangeur refroidisseur du genre de ceux utilisés dans les véhicules automobiles. Ces tubes sont reliés entre eux de façon habituelle par des dissipateurs 2 constitués, par exemple, par des bandes ondulées ou par des ailettes.In the drawing, 1 denotes the circulation tubes of a heat exchanger, in particular of a cooling exchanger of the kind used in motor vehicles. These tubes are connected together in the usual way by dissipators 2 constituted, for example, by corrugated strips or by fins.

Les extrémités des tubes 1 sont engagées dans des plaques collectrices 3 qui présentent, à leur périphérie, une gorge 4 et un bord montant externe 5. Les plaques collectrices 3 que comporte l'échangeur sont fabriquées en un métal ou en un alliage compatible avec le métal ou alliage des tubes 1 et des dissipateurs 2 et l'ensemble de ces pièces est réuni par brasage ou par un autre moyen.The ends of the tubes 1 are engaged in collecting plates 3 which have, at their periphery, a groove 4 and an external rising edge 5. The collecting plates 3 which the exchanger comprises are made of a metal or an alloy compatible with the metal or alloy of the tubes 1 and of the dissipators 2 and all of these parts are joined together by brazing or by another means.

Suivant l'invention, on utilise pour recouvrir les collecteurs 3 une boite à eau 6 à paroi mince qui est avantageusement fabriquée en métal, notamment par emboutissage. Bien que cela ne soit pas représenté, la boite à eau comporte de façon connue des tubulures, embases et autres conduits habituels à la technique.According to the invention, there is used to cover the collectors 3 a water box 6 with a thin wall which is advantageously made of metal, in particular by stamping. Although not shown, the water box comprises, in a known manner, pipes, bases and other conduits usual in the art.

A la fig. 1, la boite à eau présente à sa base un rebord périphérique 7 de largeur correspondant à celle de la gorge 4 de la plaque collectrice 3 et ce rebord est prolongé, notamment pour le rigidifier, par un bord montant 8.In fig. 1, the water box has at its base a peripheral rim 7 of width corresponding to that of the groove 4 of the collector plate 3 and this rim is extended, in particular to stiffen it, by a rising edge 8.

Pour mettre en place la boite à eau 6 et assurer l'étanchéité avec la plaque collectrice on procède comme suit :

  • On dispose, tout d'abord, un joint d'étanchéité déformable 9 dans le fond de la gorge 4, puis on pose la boite à eau 6 sur le joint. Une opération suivante consiste à mettre en place, entre le bord montant 8 et la paroi périphérique de la boite à eau 6, une barrette 10 qui peut être fabriquée en différentes matières mais qui doit être, de préférence, rigide et peu ou pas déformable compte tenu des efforts qu'elle doit supporter. Des résines synthétiques du genre polyamide peuvent être utilisées pour constituer la barrette qui pourrait, d'ailleurs, être métallique.
To set up the water box 6 and seal it with the collecting plate, proceed as follows:
  • First, there is a deformable seal 9 in the bottom of the groove 4, then the water box 6 is placed on the seal. A next operation consists in putting in place, between the rising edge 8 and the peripheral wall of the water box 6, a bar 10 which can be made of different materials but which should preferably be rigid and little or not deformable. held efforts that she has to endure. Synthetic polyamide-type resins can be used to form the strip which could, moreover, be metallic.

Il est avantageux, comme l'illustre le dessin, que la barrette 10 forme un bourrelet 11 recouvrant le dessus du bord montant 8 de la boîte.It is advantageous, as illustrated in the drawing, for the bar 10 to form a bead 11 covering the top of the rising edge 8 of the box.

Une opération suivante consiste à mettre en place une pince 12, bien connue en elle-même, qui em- boite le dessous de la partie de la plaque collectrice formant la gorge 4 et qui s'étend le long du bord montant 5 et dont des pattes 13 sont serties sur le dessus de la barrette 10.A next operation consists in putting in place a clamp 12, well known in itself, which wraps the underside of the part of the collecting plate forming the groove 4 and which extends along the rising edge 5 and of which tabs 13 are crimped onto the top of the bar 10.

Il est avantageux que la barrette s'étende sur les quatre côtés de la plaque collectrice. En outre, le dessus lOa de la barrette est de préférence situé au-dessus du bord du collecteur pour que la pliure 13a des pattes n'engendre pas une ligne de fatigue.It is advantageous that the strip extends over the four sides of the collector plate. In addition, the top 10a of the bar is preferably located above the edge of the collector so that the fold 13a of the legs does not generate a line of fatigue.

Etant donné que les plaques collectrices sont le plus souvent d'une largeur uniforme, il est avante- geux, comme l'illustre la fig. 3, de réaliser par moulage des barrettes 10 présentant la forme d'un cadre rectangulaire dont les dimensions correspondent à celles de la plus grande plaque collectrice pouvant être utilisée et ces barrettes en forme de cadre rectangulaire sont ensuite coupées à longueur, comme illustré par exemple par les traits de coupe 14 montrés à la fig. 3. Il est évidemment possible, si on le désire, de former des barrettes en forme de cadre rectangulaire pour chaque type d'échangeur, de même, on ne sortirait pas du cadre de l'invention en fabriquant des demi-cadres dont les côtés seraient ensuite coupés à longueur ou en utilisant des tronçons de barrettes qui seraient disposés dans les quatre côtés de la gorge de chaque plaque collectrice.Since the collector plates are most often of uniform width, it is advantageous, as illustrated in FIG. 3, to produce by molding bars 10 having the shape of a rectangular frame whose dimensions correspond to those of the largest collecting plate that can be used and these bars in the shape of rectangular frame are then cut to length, as illustrated for example by the section lines 14 shown in FIG. 3. It is obviously possible, if desired, to form bars in the form of a rectangular frame for each type of exchanger, similarly, it would not go beyond the scope of the invention to manufacture half-frames whose sides would then be cut to length or by using sections of bars which would be arranged in the four sides of the groove of each collector plate.

La fig. 2 illustre une légère variante suivant laquelle la pince 12 n'est pas utilisée. Dans ce cas, c'est le bord montant 5 de la plaque collectrice qui est pourvu de pattes 13 serties sur le dessus de la barrette 10. Dans cette réalisation, le bord lOb au moins de la barrette est arrondi pour que la pliure des pattes 13 soit effectuée dans de bonnes conditions.Fig. 2 illustrates a slight variant according to which the clamp 12 is not used. In this case, it is the rising edge 5 of the collecting plate which is provided with lugs 13 crimped on the top of the bar 10. In this embodiment, the edge lOb at least of the bar is rounded so that the bending of the legs 13 is carried out in good conditions.

La fig. 4 illustre une réalisation simplifiée selon laquelle la boite à eau 6 ne présente pas de bord montant 8 comme dans les réalisations précédentes, mais est seulement entourée par un rebord plan 7a. Dans ce cas, on place comme précédemment sur le dessus du rebord une barrette 10a dont la largeur correspond à celle du rebord 7a et les pattes 13a de la plaque collectrice 3 sont serties comme illustré à la fig. 2 sur le dessus de la barrette.Fig. 4 illustrates a simplified embodiment according to which the water box 6 does not have a rising edge 8 as in the previous embodiments, but is only surrounded by a flat rim 7a. In this case, place as above on the top of the rim a bar 10a whose width corresponds to that of the rim 7a and the lugs 13a of the collector plate 3 are crimped as illustrated in FIG. 2 on the top of the bar.

Dans cette réalisation, on pourrait, de la même façon, utiliser la pince 12 de la fig. 1.In this embodiment, one could, in the same way, use the clamp 12 of FIG. 1.

Les fig. 5 et 6 illustrent un développement de l'invention qui est mis en oeuvre dans la réalisation décrite ci-dessus en référence à la fig. 2 mais qui peut, évidemment, s'appliquer aux autres réalisations.Figs. 5 and 6 illustrate a development of the invention which is implemented in the embodiment described above with reference to FIG. 2 but which can obviously apply to other embodiments.

Suivant ce développement, des encoches à fond courbe, par exemple concave, sont formées dans les barrettes et les pattes 13 sont repliées dans les encoches et déformées de façon correspondant au fond, ce qui augmente considérablement la raideur des pattes.According to this development, notches with a curved bottom, for example concave, are formed in the bars and the tabs 13 are folded back in the notches and deformed corresponding to the bottom, which considerably increases the stiffness of the tabs.

Dans tous les cas, la barrette qui est en matière dure supporte les efforts dus au sertissage et répartit ces efforts sur le rebord 7 ou 7a de la boite à eau, rebord qui s'applique ainsi sous une pression uniforme sur le joint d'étanchéité 9.In all cases, the bar which is made of hard material supports the forces due to crimping and distributes these forces on the rim 7 or 7a of the water box, rim which is thus applied under uniform pressure on the seal. 9.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiments shown and described in detail, because various modifications can be made without departing from its scope.

En particulier, les boites à eau peuvent être fabriquées en matière synthétique tout en présentant une paroi mince normalement déformable sous l'influence de la force habituellement appliquée par les pattes 13 si les barrettes 10 n'étaient pas utilisées. On peut, ainsi, fabriquer des boîtes à eau d'un prix de revient bien plus faible que celui des boites en matière synthétique moulées dont l'épaisseur doit empêcher toute déformation de la partie appliquée sur le joint 9 par les pattes 13.In particular, the water boxes can be made of synthetic material while having a thin wall normally deformable under the influence of the force usually applied by the legs 13 if the bars 10 were not used. It is thus possible to manufacture water boxes at a much lower cost price than that of molded plastic boxes, the thickness of which must prevent any deformation of the part applied to the seal 9 by the tabs 13.
