Abstract
Description
La présente invention concerne un procédé de fabrication d'un réservoir destiné à être intégré dans un échangeur thermique.The present invention relates to a method of manufacturing a tank intended to be integrated in a heat exchanger.
Dans l'automobile, les échangeurs thermiques tels que les climatiseurs utilisent un réservoir qui est raccordé au tube collecteur, lui-même raccordé aux ailettes de refroidissement.In the automobile, heat exchangers such as air conditioners use a tank that is connected to the collector pipe, itself connected to the cooling fins.
La fabrication préalable du réservoir telle qu'elle est faite actuellement consiste essentiellement à extruder une pièce sous la forme d'une pièce tubulaire et à rapporter à l'une des extrémités ouvertes une pièce formant rondelle que l'on vient fixer ultérieurement par brasage avec fluxage.The prior manufacture of the tank as it is currently done essentially consists in extruding a piece in the form of a tubular piece and in bringing back to one of the open ends a piece forming a washer which is subsequently fixed by brazing with fluxing.
Ce procédé permet globalement d'obtenir un réservoir fiable et étanche. Cependant, de par la nature de fabrication du tube par extrusion et plus particulièrement de la rondelle stop insérée au milieu du tube, il s'avère que le positionnement du filtre logé dans le réservoir n'est pas satisfaisant à coup sûr. En outre, le temps et le coût de fabrication d'un tel réservoir peuvent s'avérer élevés.This process generally makes it possible to obtain a reliable and watertight tank. However, by the extrusion tube manufacturing nature and more particularly the stop washer inserted in the middle of the tube, it turns out that the positioning of the filter housed in the tank is not satisfactory for sure. In addition, the time and cost of manufacturing such a tank can be high.
Le brevet
Ainsi, la présente invention a pour objectif de résoudre les inconvénients précités à l'aide de moyens simples, faciles à mettre en oeuvre et peu onéreux.Thus, the present invention aims to solve the aforementioned drawbacks using simple means, easy to implement and inexpensive.
A cet effet, l'invention concerne un procédé de fabrication d'un réservoir destiné à être intégré dans un échangeur thermique du type consistant dans une étape à rouler une feuille de métal sur elle-même puis à souder entre eux les bords roulés afin de constituer un tube puis dans une étape ultérieure à placer, à l'une des extrémités du tube, un bouchon et à l'autre des extrémités un embout destiné à loger un filtre puis enfin à fixer et étancher par brasage le bouchon et l'embout au tube, caractérisé en ce qu'au préalable, on réalise un plaquage de la face du tube constituant la paroi intérieure d'un métal de brasage, en ce qu'on réalise l'étape de placement du bouchon et d'une bague, destinée à loger intérieurement l'embout, par emmanchement à l'intérieur du tube, l'étape de fixation et étanchéification du bouchon et de la bague étant réalisée par brasage du métal plaqué sur la paroi intérieure du tube tandis que celle de l'embout est réalisée par emmanchement dans la bague avec interposition d'un joint entre eux puis fixation de l'embout au tube.To this end, the invention relates to a method of manufacturing a reservoir intended to be integrated in a heat exchanger of the type consisting in a step of rolling a sheet of metal on itself and then welding the rolled edges together in order to constitute a tube and in a subsequent step to place, at one end of the tube, a plug and at the other end a nozzle for housing a filter and finally to fix and seal by soldering the plug and the tip to the tube, characterized in that beforehand, it carries out a plating of the face of the tube constituting the inner wall of a solder metal, in that the step of placing the stopper and a ring is carried out, intended to house the tip internally, by fitting inside the tube, the fixing and sealing step of the plug and the ring being performed by brazing the plated metal on the inner wall of the tube while that of the tip is performed by fitting into the ring with interposition of a seal between them and then fixing the tip to the tube.
Par « plaquage », il faut comprendre ici et dans le cadre de l'invention une opération de dépôt d'un revêtement de métal destiné à fournir le métal de brasage ultérieurement, tel que de l'aluminium.By "plating" is understood here and in the context of the invention a deposit operation of a metal coating for providing the subsequent solder metal, such as aluminum.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings which are given by way of non-limiting examples.
La figure 1 est une vue en coupe transversale d'un réservoir selon l'état de l'art ;Figure 1 is a cross-sectional view of a tank according to the state of the art;
La figure 2 est une vue en coupe transversale d'un réservoir selon l'invention.Figure 2 is a cross-sectional view of a tank according to the invention.
Par souci de clarté, les références désignant les mêmes parties de pièces selon l'état de l'art et selon l'invention sont identiques. Les réservoirs selon l'état de l'art et selon l'invention (1) sont destinés à être intégré dans un échangeur thermique non représenté en totalité.For the sake of clarity, the references designating the same parts of parts according to the state of the art and according to the invention are identical. Tanks according to the state of the art and according to the invention (1) are intended to be integrated in a heat exchanger not shown in full.
Le réservoir (1) représenté à la figure 1 comprend selon l'état de l'art un tube (10) réalisé en une seule pièce par extrusion dont une extrémité (11) forme l'embout d'un filtre et qui présente intérieurement une collerette (12) formant rondelle d'arrêt pour la partie embout mâle du filtre non représentée. A l'autre extrémité du tube (13) est fixée par brasage avec fluxage une cloison formant bouchon (2). Le brasage avec fluxage est une soudure qui s'effectue de manière connue en soi en chauffant l'ensemble assemblé (10,2) pour faire fondre la couche d'aluminium qui recouvre uniquement le bouchon (2) et obtenir ainsi une liaison parfaitement étanche entre ces deux pièces (10,2).The tank (1) shown in FIG. 1 comprises, according to the state of the art, a tube (10) made in one piece by extrusion, one end of which (11) forms the end of a filter and which has the inside a flange (12) forming a locking washer for the male end portion of the not shown filter. At the other end of the tube (13) is attached by fluxing a plug wall (2). Brazing with fluxing is a welding which is carried out in a manner known per se by heating the assembled assembly (10,2) to melt the aluminum layer which covers only the plug (2) and thus obtain a perfectly sealed connection between these two pieces (10,2).
Le temps et coût de production pour réaliser ce tube collecteur (10) sont trop élevés.The time and cost of production to make this collector tube (10) are too high.
Pour résoudre ces inconvénients, selon le mode de réalisation illustré de l'invention, il est proposé un procédé de fabrication d'un réservoir (1) destiné à être intégré dans un échangeur thermique (1) du type consistant dans une étape à rouler une feuille de métal sur elle-même puis à souder entre eux les bords roulés afin de constituer un tube (10) puis dans une étape ultérieure à placer, à l'une des extrémités (13) du tube, un bouchon (2) et à l'autre des extrémités (11) un embout (3) destiné à loger un filtre puis enfin à fixer et étancher par brasage le bouchon (2) et l'embout (3) au tube (10).To solve these disadvantages, according to the illustrated embodiment of the invention, there is provided a method of manufacturing a tank (1) intended to be integrated in a heat exchanger (1) of the type consisting of a step to roll a sheet of metal on itself and then weld together the rolled edges to form a tube (10) and in a subsequent step to place, at one end (13) of the tube, a plug (2) and to the other end (11) a nozzle (3) for housing a filter and finally to fix and seal by sealing the plug (2) and the tip (3) to the tube (10).
Selon le mode de réalisation illustré, au préalable, on réalise un plaquage de la face du tube (10) constituant la paroi intérieure (100) d'un métal de brasage, en ce qu'on réalise l'étape de placement du bouchon (2) et d'une bague (4), destinée à loger intérieurement l'embout (3), par emmanchement à l'intérieur du tube (10), l'étape de fixation et étanchéification du bouchon (2) et de la bague (4) étant réalisée par brasage du métal plaqué sur la paroi intérieure (100) du tube (10) tandis que celle de l'embout (3) est réalisée par emmanchement dans la bague avec interposition d'un joint (5) entre eux puis fixation de l'embout au tube (10).According to the embodiment illustrated, beforehand, a plating of the face of the tube (10) constituting the inner wall (100) of a brazing metal is carried out, in that the cork placement step is carried out ( 2) and a ring (4), intended to house the end piece (3), by fitting inside the tube (10), the step of fixing and sealing the plug (2) and the ring (4) being made by brazing the plated metal on the inner wall (100) of the tube (10) while that of the tip (3) is formed by fitting into the ring with interposition of a seal (5) between them then attaching the tip to the tube (10).
La fixation mécanique ou autre entre l'embout (3) et le tube (10) intervenant après le brasage du métal plaqué, il est possible de choisir un embout (3) réalisé en matière plastique et de le fixer au tube par accrochage mécanique de type clippage comme décrit ci-après, solution simple et économique.The mechanical attachment or other between the endpiece (3) and the tube (10) occurring after the brazing of the plated metal, it is possible to choose a tip (3) made of plastic material and fix it to the tube by mechanical attachment of clipping type as described below, simple and economical solution.
Selon une variante avantageuse, on réalise le plaquage de la face (100) du tube (10) avant son roulage.According to an advantageous variant, the plating of the face (100) of the tube (10) is carried out before rolling.
Selon le mode de réalisation préféré et illustré, avant l'emmanchement de l'embout (3) à l'intérieur du tube (10), il comporte une étape intermédiaire d'emmanchement à l'intérieur du tube d'une rondelle (12) destinée à servir de butée au filtre lui-même destiné à être logé dans l'embout, l'étanchéification de la rondelle (12) avec le tube (10) étant réalisée par brasage du métal plaqué sur la paroi intérieure (100) du tube.According to the preferred embodiment and illustrated, before the fitting of the tip (3) inside the tube (10), it comprises an intermediate step of fitting inside the tube of a washer (12). ) intended to serve as a stop for the filter itself intended to be housed in the nozzle, the sealing of the washer (12) with the tube (10) being made by brazing the plated metal on the inner wall (100) of the tube.
Selon le mode de réalisation illustré, avant l'étape d'emmanchement de la rondelle (12), on déforme vers l'intérieur du tube (10) la paroi intérieure (100) de ce dernier afin de constituer une butée de positionnement longitudinale de la rondelle.According to the illustrated embodiment, before the step of fitting the washer (12), the inner wall (100) of the latter is deformed towards the inside of the tube (10) so as to constitute a longitudinal positioning stop of the puck.
De préférence, on réalise l'étape de brasage du métal plaqué intérieurement dans le tube (10) lors de l'étape de brasage avec fluxage globale de l'échangeur thermique.Preferably, the step of brazing the metal plated internally in the tube (10) during the soldering step with global fluxing of the heat exchanger.
Selon le mode de réalisation illustré et préféré, on réalise préalablement un plaquage de la face du tube (10) constituant la paroi extérieure (101) d'un métal de brasage, le brasage de ce dernier permettant la fixation et l'étanchéification entre le tube et les éléments de fixation de l'échangeur thermique.According to the illustrated and preferred embodiment, a plating of the face of the tube (10) constituting the outer wall (101) of a brazing metal is carried out beforehand, the brazing of the latter allowing the fixing and the sealing between the tube and the fastening elements of the heat exchanger.
De préférence, on réalise l'étape de brasage du métal plaqué extérieurement (101) au tube (10) lors de l'étape avec fluxage globale de l'échangeur thermique.Preferably, the step of soldering the externally plated metal (101) to the tube (10) during the step with global fluxing of the heat exchanger is carried out.
Selon le mode de réalisation illustré, la fixation de l'embout (3) emmanché dans la bague au tube (10) est réalisée par emboîtement d'ergots (30) élastiquement déformables, pratiqués à la périphérie de l'embout (3), dans des fentes (102) pratiquées à l'extrémité du tube (10).According to the illustrated embodiment, the attachment of the tip (3) fitted into the ring to the tube (10) is formed by interlocking pins (30) elastically deformable, formed at the periphery of the tip (3), in slots (102) formed at the end of the tube (10).
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the embodiments described and represented by way of examples, but it also includes all the technical equivalents as well as their combinations.
Ainsi, une fois le brasage du métal plaqué réalisé, il est tout à fait possible de réaliser la fixation de l'embout au tube par tous autres moyens que l'emboîtement élastique décrit précédemment.Thus, once the brazing of the plated metal made, it is quite possible to achieve the attachment of the tip to the tube by any other means than the elastic interlock described above.
