Abstract
Description
La présente invention concerne les échangeurs de chaleur dont les plaques collectrices sont réalisées en matière synthétique et dont les tubes de circulation sont collés aux plaques collectrices. The present invention relates to heat exchangers whose collector plates are made of synthetic material and whose circulation tubes are glued to the collector plates.
Il a été proposé, par exemple dans leBE 0 000 189, de réaliser des échangeurs du type rappelé ci-dessus. It has been proposed, for example in BE 0 000 189, to produce exchangers of the type mentioned above.
Pour permettre d'assurer avec certitude l'étanchéité entre les extrémités des tubes et les plaques collectrices, la publication ci-dessus prévoit de former sur le côté extérieur des fonds des plaques collectrices des embouts tubulaires qui sont entourés par des nervures également annulaires afin de délimiter des rainures dans lesquelles la colle est mise en place avant que les tubes de circulation soient eux-mêmes enfilés sur les embouts tubulaires en butant contre le fond des plaques collectrices. To allow ensuring with certainty the seal between the ends of the tubes and the collector plates, the above publication provides for forming on the outside of the bases of the collector plates tubular end pieces which are surrounded by ribs also annular in order to delimit grooves in which the glue is put in place before the circulation tubes are themselves threaded onto the tubular ends by abutting against the bottom of the collector plates.
Cette disposition qui apparait satisfaisante pour réaliser une bonne étanchéité entre les tubes et les plaques collectrices nécessite cependant de gonfler au préalable les extrémités des tubes pour ne pas réduire, de façon néfaste, leur section de passage étant donné que les tubes coiffent les embouts tubulaires. This arrangement, which appears satisfactory for achieving a good seal between the tubes and the collector plates, however, requires that the ends of the tubes be inflated beforehand so as not to adversely reduce their cross-section, given that the tubes cover the tubular ends.
La disposition selon la publication ci-dessus n'élimine pas le risque de coulures de colle à l'intérieur des tubes ce qui peut conduire à une obstruction au moins partielle de certains tubes. The arrangement according to the above publication does not eliminate the risk of glue dripping inside the tubes, which can lead to at least partial obstruction of certain tubes.
L'invention remédie aux inconvénients ci-dessus. The invention overcomes the above drawbacks.
Conformément à l'invention, le procédé pour la liaison entre les tubes et les plaques collectrices d'un échangeur de chaleur dans lequel les plaques collectrices sont fabriquées en résine synthétique et les tubes de circulation devant être reliés à au moins une plaque collectrice sont fabriqués en métal, est caractérisé en ce qu'on forme dans la plaque collectrice pour chaque tube un logement délimitant un segment d'entrée prolongé par un segment élargi, ledit segment d'entrée formant guide pour le tube dont la paroi délimite avec le segment élargi une chambre annulaire qui est remplie au moins partiellement d'une colle. According to the invention, the method for the connection between the tubes and the collector plates of a heat exchanger in which the collector plates are made of synthetic resin and the circulation tubes to be connected to at least one collector plate are manufactured made of metal, is characterized in that a housing is defined in the collecting plate for each tube delimiting an inlet segment extended by an enlarged segment, said inlet segment forming a guide for the tube, the wall of which delimits with the enlarged segment an annular chamber which is at least partially filled with an adhesive.
L'invention s'étend en outre à un échangeur de chaleur. The invention further extends to a heat exchanger.
Conformément à cette seconde disposition de l'invention, l'échangeur de chaleur obtenu par la mise en oeuvre du procédé est caractérisé en ce que les tubes de circulation sont engagés dans des logements de plaques collectrices par un segment d'entrée et de guidage en délimitant avec la plaque collectrice, à chaque fois, une chambre annulaire remplie de colle durcie. According to this second arrangement of the invention, the heat exchanger obtained by the implementation of the method is characterized in that the circulation tubes are engaged in housings of manifold plates by an inlet and guide segment in each time, delimiting with the collecting plate an annular chamber filled with hardened glue.
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'exemples non limitatifs, au dessin annexé. Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.

La fig. 3 est une coupe-élévation partielle et schématique d'un échangeur de chaleur réalisé selon l'invention. Fig. 3 is a partial and schematic sectional elevation of a heat exchanger produced according to the invention.
La fig. 4 est un plan montrant un mode d'exécution d'une opération du procédé de l'invention. Fig. 4 is a plan showing an embodiment of an operation of the method of the invention.
Au dessin, 1 désigne une plaque collectrice pour des tubes 2 d'un échangeur de chaleur. Les plaques collectrices sont fabriquées en matière synthétique et présentent une épaisseur notable tandis que les tubes 2 sont métalliques. In the drawing, 1 denotes a collecting plate for tubes 2 of a heat exchanger. The collector plates are made of synthetic material and have a significant thickness while the tubes 2 are metallic.
Au dessin, les tubes sont de section oblongue mais l'invention s'applique de la même manière quelle que soit la forme en section desdits tubes. In the drawing, the tubes are of oblong section but the invention applies in the same way regardless of the sectional shape of said tubes.
Les plaques collectrices 1 sont réalisées par moulage et délimitent, dans leur épaisseur, des logements 3 correspondant à chaque tube 2, ces logements présentant un segment d'entrée 4 de forme et dimension correspondant à celles d'un tube 2 de manière que ledit tube 2 puisse être engagé dans le segment d'entrée 4 à frottement doux, ce qui assure son guidage et son centrage dans le logement. The collector plates 1 are produced by molding and delimit, in their thickness, housings 3 corresponding to each tube 2, these housings having an inlet segment 4 of shape and dimension corresponding to those of a tube 2 so that said tube 2 can be engaged in the entry segment 4 with gentle friction, which ensures its guiding and centering in the housing.
Le logement 3 présente au-dessus du segment 4 un segment élargi 5 destiné à délimiter une chambre annulaire 6 avec le tube 2. Finalement, bien que cela ne soit pas nécessaire, il est avantageux que le segment élargi 5 soit prolongé par un segment évasé 7. The housing 3 has above the segment 4 an enlarged segment 5 intended to delimit an annular chamber 6 with the tube 2. Finally, although this is not necessary, it is advantageous that the enlarged segment 5 is extended by a flared segment 7.
Les tubes 2 présentent avantageusement une-extrémité restreinte 2a pour faciliter leur engagement dans le logement 3 correspondant. The tubes 2 advantageously have a restricted end 2a to facilitate their engagement in the corresponding housing 3.
Pour réaliser un échangeur de chaleur on procède comme suit. On engage les tubes 2 dans des dissipateurs 8, par exemple des ailettes, et les tubes sont soit gonflés dans les ailettes, soit brasés dans celles-ci pour constituer un faisceau tubulaires Les extrémités des tubes sont ensuite engagées par le segment d'entrée 4 à l'intérieur du logement 3 pour faire saillie au-dessus de la plaque collectrice 1, comme le montre la fig. 2. To make a heat exchanger, proceed as follows. The tubes 2 are engaged in dissipators 8, for example fins, and the tubes are either inflated in the fins, or brazed therein to form a tube bundle The ends of the tubes are then engaged by the inlet segment 4 inside the housing 3 to project above the collecting plate 1, as shown in fig. 2.
Une matière plastique durcissable, par exemple une colle liquide fabriquée à partir de résine synthétique, est ensuite versée ou injectée dans la chambre 6 en l'introduisant par exemple par le segment évasé 7. Des résines époxydes peuvent avantageusement être utilisées à cette fin. A curable plastic material, for example a liquid adhesive made from synthetic resin, is then poured or injected into the chamber 6 by introducing it, for example, through the flared segment 7. Epoxy resins can advantageously be used for this purpose.
Lorsque toutes les chambres 6 et tous les segments évasés 7 sont convenablement remplis, l'échangeur est étuvé pour tout d'abord fluidifier la colle afin que celle-ci mouille complètement la paroi de la chambre 6 et la paroi correspondante de chaque tube 2 puis l'opération d'étuvage provoque le durcissement de la résine qui adhère fortement tant à la plaque collectrice qu'au tube en assurant, par conséquent, à la fois la jonction mécanique entre la plaque collectrice et les tubes et l'éwar.chéité qui est nécessaire au bon fonctionnement de l'échangeur. When all the chambers 6 and all the flared segments 7 are suitably filled, the exchanger is steamed to first fluidize the adhesive so that it completely wets the wall of the chamber 6 and the corresponding wall of each tube 2 then the steaming operation causes the resin to harden, which adheres strongly to both the collector plate and the tube, thereby ensuring both the mechanical junction between the collector plate and the tubes and the sealing which is necessary for the proper functioning of the exchanger.
Le segment d'entrée 4 étant de forme et dimension correspondant à celles du tube a pour fonction, outre le guidage déjà décrit, de retenir la colle dans la chambre 6 en empêchant que cette colle s'écoule le long de la paroi du tube lorsqu'elle passe par sa phase fluide. The inlet segment 4 being of shape and dimension corresponding to those of the tube has the function, in addition to the guidance already described, of retaining the glue in the chamber 6 by preventing this glue from flowing along the wall of the tube when 'it goes through its fluid phase.
Lorsque l'échangeur de chaleur comporte deux plaques collectrices 1,la, comme montré a la fig. 3, ces deux plaques collectrices peuvent être identiques et toutes deux disposées de la même manière, c'est-à-dire pour que le segment évasé 7 soit dirigé vers le haut lorsque les tubes 2 sont verticaux. Cette disposition se prête particulièrement bien à une fabrication entièrement mécanique de l'échangeur. When the heat exchanger comprises two manifold plates 1, la, as shown in FIG. 3, these two collector plates can be identical and both arranged in the same way, that is to say so that the flared segment 7 is directed upwards when the tubes 2 are vertical. This arrangement is particularly suitable for fully mechanical manufacture of the exchanger.
En effet, les tubes 2 peuvent être engagés dans une même opération à travers la plaque collectrice la à travers les dissipateurs 8 puis à travers la plaque collectrice 1, les passages de tubes des dissipateurs 8 étant légèrement déformés lors de l'introduction des tubes pour réaliser un bon accostage mécanique entre ces pièces. In fact, the tubes 2 can be engaged in the same operation through the collecting plate 1a through the dissipators 8 then through the collecting plate 1, the passages of the tubes of the dissipators 8 being slightly deformed during the introduction of the tubes for achieve good mechanical docking between these parts.
La colle est ensuite introduite dans les chambres 6 des deux plaques collectrices et l'ensemble de l'échangeur est étuvé en position verticale de sorte qu'il n'existe aucun risque d'écoulement accidentel lors du passage en phase fluide de la colle. The adhesive is then introduced into the chambers 6 of the two collecting plates and the whole of the exchanger is steamed in a vertical position so that there is no risk of accidental flow during the passage of the adhesive in the fluid phase.
Un autre mode de montage peut évidemment être utilisé au gré du fabricant En effet, l'enseble tube 2, dissipateur 8 peut entre fabriqué à l'avance et les extrémités des tubes engagées ultérieurement dans l'une et l'autre des deux plaques collectrices 1, la. Another mounting method can obviously be used at the discretion of the manufacturer. Indeed, the whole tube 2, dissipator 8 can between manufactured in advance and the ends of the tubes subsequently engaged in one and the other of the two collector plates. 1, the.
Les plaques collectrices 1, la peuvent être munies de boîtes à eau 9, 9a, soit avant , soit après l'engagement des tubes. Lorsque l'ensemble tube 2, dissipateur 8 est fabriqué à l'avance, il est même possible d'utiliser des plaques collectrices pré-assemblées à leurs boîtes à eau. The collecting plates 1, la can be provided with water boxes 9, 9a, either before or after the engagement of the tubes. When the tube 2, dissipator 8 assembly is manufactured in advance, it is even possible to use collector plates pre-assembled to their water boxes.
En effet, comme le montre la fig. 4, selon un développement de l'invention il est possible que les plaques collectrices présentent, à partir de leur côté, des canaux d'injection 10 permettant d'introduire une quantité mesurée de colle aprbsle montage des tubes. Indeed, as shown in fig. 4, according to a development of the invention, it is possible that the collector plates have, from their side, injection channels 10 making it possible to introduce a measured quantity of adhesive after mounting the tubes.
Les canaux d'injection servent au guidage de buses 11 qui damnent la colle dans la chambre 6,ladite colle assurant aussi la fermeture des canaux 10. The injection channels serve to guide nozzles 11 which damn the glue in the chamber 6, said glue also ensuring the closing of the channels 10.
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, since various modifications can be made thereto without departing from its scope.
