Description

La présente invention concerne un nouveau dispositif de liaison entre une plaque collectrice et une boîte à eau d'un échangeur de chaleur.The present invention relates to a new connecting device between a header plate and a water box of a heat exchanger.

L'invention s'applique à ceux des échangeurs de chaleur dans lesquels la plaque collectrice est recouverte par une boîte à eau qui est maintenue en place par des agrafes qui comportent des pattes prenant appui sur une portée périphérique de la boîte à eau.The invention applies to those of heat exchangers in which the collector plate is covered by a water box which is held in place by staples which have lugs bearing on a peripheral surface of the water box.

Il est bien connu dans la technique de prévoir des agrafes qui sont mises en place après l'assemblage de la boite à eau et dont des pattes saillantes sont repliées ou serties à la presse sur la portée d'appui de la boîte à eau, la pression exercée par la presse de sertissage faisant que le joint interposé entre la boîte à eau et la plaque collectrice est comprimé pour assurer l'étanchéité entre ces deux pièces.It is well known in the art to provide staples which are put in place after assembly of the water box and whose projecting tabs are folded or crimped with the press on the bearing surface of the water box, the pressure exerted by the crimping press causing the seal interposed between the water box and the collector plate to be compressed to seal between these two parts.

Il a été constaté que le pliage ou sertissage des pattes des agrafes n'est pas réalisé dans la pratique d'une façon uniforme de sorte que lesdites pattes exercent des pressions non uniformes sur la boîte à eau. Cet inconvénient est encore augmenté par le fait que le pliage ou sertissage des pattes de l'agrafe a souvent pour effet de déformer le dos de l'agrafe, ce qui est dû aux contraintes développées à partir de la partie pliée desdites pattes.It has been found that the folding or crimping of the tabs of the staples is not carried out in practice in a uniform manner so that said tabs exert non-uniform pressures on the water box. This drawback is further increased by the fact that the folding or crimping of the tabs of the clip often has the effect of deforming the back of the clip, which is due to the stresses developed from the folded part of said tabs.

Il résulte des facteurs énoncés ci-dessus que des défauts d'étanchéité peuvent se produire entre la plaque collectrice et la boîte à eau qui la recouvre.As a result of the factors set out above, leaks can occur between the collector plate and the water box which covers it.

La présente invention remédie à cet inconvénient.Conformément à l'invention, le dispositif de liaison entre une plaque collectrice et une boîte à eau d'un échangeur de chaleur comportant au moins une agrafe prenant appui en dessous du fond d'une gorge périphérique de la plaque collectrice, et sur le dessus d'une portée d'appui périphérique de la boîte à eau au moyen de pattes séparées par des encoches est caractérisé en ce que l'agrafe est pré-formée pour délimiter des pattes supérieures et inférieures, distantes d'une mesure pour laquelle un joint d'étanchéité interposé entre la plaque collectrice et la boîte à eau est déformé d'une manière régulière, ladite agrafe présentant au moins une patte inférieure de longueur supérieure à la largeur du fond de la gorge de la plaque collectrice et étant repliée au-delà de celui-ci.The present invention overcomes this drawback. In accordance with the invention, the connection device between a collector plate and a water box of a heat exchanger comprising at least one clip resting below the bottom of a peripheral groove of the collector plate, and on the top of a peripheral bearing surface of the water box by means of legs separated by notches is characterized in that the clip is pre-formed to delimit upper and lower legs, distant of a measure for which a seal interposed between the collector plate and the water box is deformed in a regular manner, said clip having at least one lower tab of length greater than the width of the bottom of the groove of the collector plate and being folded back beyond it.

L'invention s'étend également à un procédé pour la mise en oeuvre du dispositif ci-dessus.The invention also extends to a method for implementing the above device.

Conformément à cette seconde disposition de l'invention, le procédé pour la liaison entre une plaque collectrice et une boîte à eau d'un échangeur de chaleur dans lequel ladite liaison est assurée par une agrafe prenant appui,en dessous d'une gorge périphérique de la plaque collectrice et au-dessus d'une portée d'appui périphérique d'une boîte à eau recouvrant la plaque collectrice et serrant contre celle-ci un joint d'étanchéité est caractérisé en ce qu'on met en forme une agrafe présentant des parties d'appui supérieure et inférieure, séparées d'une distance régulière, en ce qu'on exerce un effort de compression entre la plaque collectrice et la boîte à eau pour déformer le joint d'étanchéité qui les sépare et en ce qu'on met en place l'agrafe par coulissement pour qu'elle prenne appui d'une part, sur la portée d'appui de la boîte à eau et, d'autre part, contre le fond de la gorge périphérique de la plaque collectrice. Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.According to this second arrangement of the invention, the method for the connection between a collector plate and a water box of a heat exchanger in which said connection is provided by a staple bearing, below a peripheral groove of the collector plate and above a peripheral bearing surface of a water box covering the collector plate and pressing a seal against it is characterized in that a staple is formed having upper and lower support parts, separated by a regular distance, in that a compressive force is exerted between the collecting plate and the water box to deform the seal which separates them and in that sets up the clip by sliding so that it takes support on the one hand, on the bearing surface of the water box and, on the other hand, against the bottom of the peripheral groove of the collector plate. Various other characteristics of the invention will also emerge from the detailed description which follows.

Un mode de réalisation de l'invention est représenté, à titre d'exemple non limitatif, au dessin annexé.An embodiment of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

La fig. 1 est une perspective d'une agrafe pour la réalisation du dispositif de liaison, plaque collectrice-boîte à eau, objet de l'invention.Fig. 1 is a perspective of a staple for producing the connection device, manifold-water box, object of the invention.

La fig. 2 est un plan vu de dessus, à plus petite échelle, correspondant à la fig. 1 d'une agrafe.Fig. 2 is a plan seen from above, on a smaller scale, corresponding to FIG. 1 of a staple.

La fig. 3 illustre en élévation, et en coupe sensiblement suivant la ligne III-III de la fig. 4, un outillage de mise en place du dispositif de liaison sur un ensemble plaque collectrice-boîte à eau.Fig. 3 illustrates in elevation, and in section substantially along line III-III of FIG. 4, a tool for installing the connection device on a collector plate-water box assembly.

La fig. 4 est une élévation latérale vue sensiblement suivant la ligne IV-IV de la fig. 3.Fig. 4 is a side elevation seen substantially along line IV-IV of FIG. 3.

La fig. 5 est une coupe-élévation très agrandie du dispositif de liaison et d'un détail de l'outillage pour sa mise en place.Fig. 5 is a greatly enlarged sectional elevation of the connection device and of a detail of the tools for its installation.

Au dessin, 1 désigne une plaque collectrice pour des tubes de circulation 2 d'un échangeur de chaleur. Chaque plaque collectrice 1 délimite de façon connue une gorge périphérique 3 dans laquelle est disposé un joint déformable 4, par exemple en élastomère. La plaque collectrice 1 est recouverte par une boîte à eau 5 dont le bord 5a qui est engagé dans la gorge 3 présente une portée d'appui périphérique 6.In the drawing, 1 designates a header plate for circulation tubes 2 of a heat exchanger. Each collector plate 1 delimits in a known manner a peripheral groove 3 in which is disposed a deformable seal 4, for example made of elastomer. The collecting plate 1 is covered by a water box 5, the edge 5a of which is engaged in the groove 3 has a peripheral bearing surface 6.

La liaison entre la boîte à eau 5 et la plaque collectrice 1 est assurée par des agrafes désignées dans leur ensemble par 7. Chaque agrafe comporte un dos 8 à partir duquel font saillie des pattes supérieures 9 et inférieures 10.The connection between the water box 5 and the collector plate 1 is ensured by staples designated as a whole by 7. Each clip has a back 8 from which project upper legs 9 and lower legs 10.

Les pattes supérieures 9 présentent une longueur qui est choisie pour qu'elles s'étendent sur la majeure partie de la portée d'appui périphérique 6 de la boite à eau. Les pattes inférieures 10 sont légèrement plus grandes pour s'étendre sur la majeure partie du fond 1 a de la partie de la plaque collectrice qui délimite la gorge 3 sans cependant faire saillie jusqu'au bord montant 1b de la plaque collectrice. Des pattes inférieures, dites longues, désignées par 11, sont également prévues. Il existe par exemple une patte longue 11 pour cinq pattes inférieures.The upper legs 9 have a length which is chosen so that they extend over the major part of the peripheral bearing surface 6 of the water box. The lower legs 10 are slightly larger to extend over the major part of the bottom 1a of the part of the collecting plate which delimits the groove 3 without however projecting up to the rising edge 1b of the collecting plate. Lower legs, called long, designated by 11, are also provided. There is for example a long leg 11 for five lower legs.

Le dessin, et en particulier les fig. 3 et 5, montrent que les pattes inférieures 11 font saillis, notamment au-delà du fond 1a de la gorge de la plaque collectrice.The drawing, and in particular figs. 3 and 5 show that the lower lugs 11 are BRED, in particular beyond the bottom 1a of the groove of the header plate.

L'agrafe décrite ci-dessus est fabriquée par découpage et pliage et/ou emboutissage. Il est avantageux que la hauteur h de son dos fasse que celui-ci soit parfaitement plan, c'est-à-dire que les encoches 12, respectivement 13, qui coincident et qui séparent les pattes supérieures, d'une part, et inférieures, d'autre part, s'étendent jusqu'à l'extrémité des parties arrondies 13, 14, 15 de l'agrafe.The clip described above is manufactured by cutting and folding and / or stamping. It is advantageous that the height h of its back makes it perfectly flat, that is to say that the notches 12, respectively 13, which coincide and which separate the upper legs, on the one hand, and lower , on the other hand, extend to the end of the rounded parts 13, 14, 15 of the clip.

Etant donné que l'agrafe est découpée et préformée avant sa mise en place, sa réalisation peut être très précise notamment en ce qui concerne la mesure de l'intervalle séparant les faces en regard des pattes supérieures 9 et inférieures 10.Since the staple is cut and preformed before being put in place, its production can be very precise, in particular as regards the measurement of the interval separating the facing faces of the upper legs 9 and lower legs 10.

Pour la mise en place des agrafes décrites dans ce qui précède, on procède comme suit : on fait supporter la plaque collectrice au niveau du fond 1a qu'elle délimite par des dents 16 d'un peigne 17, la largeur des dents 16 étant inférieure ou au plus égale à la largeur des encoches 13.For the installation of the staples described in the foregoing, the procedure is as follows: the collecting plate is made to support at the bottom 1 a which it delimits by teeth 16 of a comb 17, the width of the teeth 16 being less than or at most equal to the width of the notches 13.

Après mise en place du joint 4 et de la boîte à eau 5, on fait exercer sur la portée d'appui périphérique 6 de cette boîte à eau un effort de compression par des dents 18 d'un second peigne 19, lesdites dents 18 étant de largeur inférieure ou au plus égale à la largeur des encoches 12.After fitting the seal 4 and the water box 5, a compression force is exerted on the peripheral bearing surface 6 of this water box by teeth 18 of a second comb 19, said teeth 18 being of width less than or at most equal to the width of the notches 12.

La pression exercée par les peignes 17 et 19 comprime le joint 4 légèrement plus qu'il n'est nécessaire pour permettre la mise en place des agrafes 7 par coulissement et à frottement doux, comme illustré par la flèche f1 de la fig.3.The pressure exerted by the combs 17 and 19 compresses the seal 4 slightly more than is necessary to allow the staples 7 to be put in place by sliding and with gentle friction, as illustrated by the arrow f 1 in FIG. 3 .

La pression de compression peut ensuite être légèrement abaissée pour que le fond 1a de la plaque collectrice, d'une part, et la portée d'appui périphérique 6 de la boîte à eau 5, d'autre part, viennent en contact serré avec les parois correspondantes de l'agrafe.The compression pressure can then be slightly lowered so that the bottom 1a of the collector plate, on the one hand, and the peripheral bearing surface 6 of the water box 5, on the other hand, come into close contact with the corresponding walls of the clip.

Avant le retrait des peignes 17 et 19, on déplace un peigne de sertissage 20 (fig. 5) qui présente un bord continu 21 destiné à venir prendre appui sur toute la longueur du dos 8 de chaque agrafe. Le peigne 20 présente, par ailleurs, des pattes 22 correspondant aux pattes inférieures longues 11.Before the removal of the combs 17 and 19, a crimping comb 20 (fig. 5) is moved which has a continuous edge 21 intended to come to bear over the entire length of the back 8 of each clip. The comb 20 also has legs 22 corresponding to the long lower legs 11.

Le déplacement vers le haut du peigne 20, lorsqu'on considère la fig. 5, a pour effet tout d'abord d'amener le bord continu 21 contre le dos 8 de l'agrafe et donc de maintenir ce dos sur toute sa longueur avant que les pattes 22 commencent à agir sur la partie saillante des pattes inférieures longues 11.The upward movement of the comb 20, when considering FIG. 5, has the effect first of all of bringing the continuous edge 21 against the back 8 of the clip and therefore of maintaining this back over its entire length before the legs 22 begin to act on the projecting part of the long lower legs 11.

Le peigne 20 continuant son mouvement de montée, les pattes 22 provoquent le pliage de la partie saillante des pattes inférieures longues 11, ce qui est illustré en traits interrompus à la fig.5. Ce pliage assure le verrouillage de l'agrafe par rapport à l'ensemble plaque collectrice-boîte à eau sans que ce pliage ait aucun effet quant à la mesure de la distance séparant les pattes supérieures 9 des pattes inférieures 10 ou 11, de sorte que la pression de déformation du joint 4 est parfaitement uniforme tout au long de l'agrafe.The comb 20 continuing its upward movement, the legs 22 cause the projection of the protruding part of the long lower legs 11, which is illustrated in inter lines. broken in fig. 5. This folding ensures the locking of the clip relative to the manifold plate-water box assembly without this folding having any effect as to the measurement of the distance separating the upper legs 9 from the lower legs 10 or 11, so that the deformation pressure of the seal 4 is perfectly uniform throughout the staple.

L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiment shown and described in detail, since various modifications can be made without departing from its scope.
