Abstract
Description
L'invention concerne un échangeur de chaleur, notamment pour véhicule automobile, du type à faisceau de tubes et à collecteur métallique, dans lequel les extrémités des tubes du faisceau sont montées à étanchéité dans les trous du collecteur, sur lequel est fixée une boîte à eau.The invention relates to a heat exchanger, in particular for a motor vehicle, of the tube bundle and metal manifold type, in which the ends of the bundle tubes are sealingly mounted in the holes of the manifold, on which is fixed a water.
Ces échangeurs de chaleur sont destinés particulièrement à former des radiateurs de refroidissement pour les moteurs thermiques de véhicules automobiles.These heat exchangers are intended in particular to form cooling radiators for the thermal engines of motor vehicles.
Un tel échangeur de chaleur est assemblé sans soudure, l'étanchéité des tubes du faisceau avec le collecteur étant assurée par un joint en élastomère.Such a heat exchanger is assembled without welding, the sealing of the bundle tubes with the collector being ensured by an elastomer seal.
Lorsqu'un tel échangeur de chaleur est manipulé avant ou pendant son montage dans un véhicule, ou lorsqu'il a été monté dans le véhicule, il peut se produire, dans certains cas, des mouvements relatifs, en particulier par pivotement ou par torsion, du faisceau de tubes par rapport à l'ensemble collecteur-boîte à eau.When such a heat exchanger is manipulated before or during its mounting in a vehicle, or when it has been mounted in the vehicle, there may be, in certain cases, relative movements, in particular by pivoting or by twisting, of the tube bundle with respect to the manifold-water box assembly.
De tels mouvements relatifs peuvent être occasionnés notamment sous l'effet de la pression et des contraintes mécaniques transmises aux boîtes à eau par les points de fixation de l'échangeur de chaleur.Such relative movements can be caused in particular under the effect of pressure and mechanical stresses transmitted to the water boxes by the fixing points of the heat exchanger.
Ce phénomène de pivotement ou de torsion est particulièrement critique lorsque le faisceau ne comporte qu'une seule rangée de tubes.This pivoting or torsion phenomenon is particularly critical when the bundle has only one row of tubes.
Pour éviter cet inconvénient, il est connu de relier les deux boîtes à eau d'un échangeur de chaleur par des traverses permettant de rigidifier l'ensemble. Cette solution a toutefois pour inconvénient de nécessiter des pièces supplémentaires et d'impliquer une forme de boîte et une machine spécifique pour sertir les traverses.To avoid this drawback, it is known to connect the two water boxes of a heat exchanger by crosspieces making it possible to stiffen the assembly. However, this solution has the disadvantage of requiring additional parts and to involve a box form and a specific machine for crimping the crosspieces.
D'autres solutions ont également été mises au point pour assurer une liaison rigide entre un faisceau de tubes et un ensemble collecteur-boîte à eau.Other solutions have also been developed to provide a rigid connection between a bundle of tubes and a collector-water box assembly.
Ainsi, le Brevet français No 84 02964, publié sous le No 2 560 368, décrit un échangeur de chaleur qui comprend des moyens d'immobilisation coopérant avec des ailettes ou analogues portés par les tubes du faisceau pour s'opposer à un déplacement relatif, en particulier par pivotement ou torsion, du faisceau par rapport à l'ensemble collecteurboîte à eau.Thus, French Patent No 84 02964, published under No 2 560 368, describes a heat exchanger which comprises immobilization means cooperating with fins or the like carried by the tubes of the bundle to oppose relative displacement, in particular by pivoting or twisting, of the beam relative to the manifold-water box assembly.
Dans cet échangeur de chaleur connu, ces moyens d'immobilisation sont constitués par des pattes venues de moulage avec la boîte à eau, ce qui oblige à prévoir des boîtes à eau spécifiques.In this known heat exchanger, these immobilization means are constituted by tabs molded with the water box, which requires to provide specific water boxes.
L'invention vient apporter une autre solution.The invention provides another solution.
Elle propose à cet effet un échangeur de chaleur du type défini précédemment, dans lequel les moyens d'immobilisation comprennent des pattes d'immobilisation, repliées et formées d'une seule pièce avec le collecteur métallique et s'étendant parallèlement à la direction des tubes de manière à prendre appui contre les bords d'un certain nombre d'ailettes du faisceau.To this end, it offers a heat exchanger of the type defined above, in which the immobilization means comprise immobilization tabs, folded and formed in one piece with the metal manifold and extending parallel to the direction of the tubes so as to bear against the edges of a certain number of fins of the beam.
Ces pattes d'immobilisation sont donc réalisées monobloc avec le collecteur, l'ensemble pouvant être fabriqué facilement par des opérations classiques de découpage, d'emboutissage et de pliage d'une tôle métallique.These immobilization tabs are therefore produced in one piece with the collector, the assembly being able to be easily manufactured by conventional operations of cutting, stamping and bending of a metal sheet.
Il n'est alors plus nécessaire de prévoir des boîtes à eau spécifiques.It is then no longer necessary to provide specific water boxes.
Dans une forme de réalisation préférée de l'invention, l'échangeur de chaleur comprend deux pattes repliées prévues aux extrémités longitudinales du collecteur de manière à recevoir les extrémités longitudinales d'un certain nombre d'ailettes du faisceau.In a preferred embodiment of the invention, the heat exchanger comprises two folded tabs provided at the longitudinal ends of the manifold so as to receive the longitudinal ends of a certain number of fins of the bundle.
Selon une autre caractéristique de l'invention, les pattes repliées ont, en section, sensiblement la forme d'un U.According to another characteristic of the invention, the folded tabs have, in section, substantially the shape of a U.
De préférence, chacune des pattes comprend une âme de forme générale rectangulaire reliée au collecteur par une languette et deux ailes repliées à angle droit par rapport à l'âme, l'âme venant prendre appui contre une face d'extrémité du faisceau et les deux ailes venant prendre appui contre deux faces longitudinales du faisceau.Preferably, each of the legs comprises a generally rectangular core connected to the collector by a tongue and two wings folded at right angles to the core, the core coming to bear against an end face of the bundle and the two wings coming to bear against two longitudinal faces of the beam.
Les deux pattes en forme de U viennent ainsi coiffer le faisceau à ses deux extrémités longitudinales.The two U-shaped legs thus cover the bundle at its two longitudinal ends.
Selon une autre caractéristique de l'invention, les pattes repliées ont des bords légèrement ouverts afin de faciliter le montage du faisceau et de ne pas blesser les ailettes.According to another characteristic of the invention, the folded legs have slightly open edges in order to facilitate the mounting of the bundle and not to injure the fins.
De façon avantageuse, le collecteur et les pattes d'immobilisation sont formés à partir d'un flan de tôle préalablement découpé et embouti.Advantageously, the collector and the immobilization tabs are formed from a sheet blank previously cut and stamped.
Ainsi, les pattes sont formées initialement dans le plan du flan de tôle puis repliées.Thus, the tabs are formed initially in the plane of the sheet blank and then folded.
Dans la description qui suit, faite seulement à titre d'exemple, on se réfère au dessin annexé, sur lequel :
- la figure 1 est une vue partielle en élévation, avec une coupe partielle, d'un échangeur de chaleur selon l'invention;
- la figure 2 est une vue partielle de côté correspondante;
- la figure 3 est une vue partielle de dessus du même échangeur de chaleur; et
- la figure 4 est une vue partielle de côté montrant le collecteur selon l'invention.
- Figure 1 is a partial elevational view, with a partial section, of a heat exchanger according to the invention;
- Figure 2 is a partial side view corresponding;
- Figure 3 is a partial top view of the same heat exchanger; and
- Figure 4 is a partial side view showing the collector according to the invention.
L'échangeur de chaleur représenté partiellement aux figures 1 à 3 comprend un faisceau 10 formé d'une seule rangée de tubes 12 alignés traversant une multiplicité d'ailettes planes 14 parallèles entre elles et s'étendant perpendiculairement à la direction des tubes 12.The heat exchanger partially shown in FIGS. 1 to 3 comprises a
Les extrémités de ces tubes sont montées à étanchéité dans les trous 16 (figure 3) d'un collecteur 18 (encore appelé "plaque à tubes" ou "plaque à trous") comprenant à sa périphérie des pattes de sertissage 20 qui sont rabattues sur le rebord périphérique 22 d'une boîte à eau 24 de type classique.The ends of these tubes are mounted in a sealed manner in the holes 16 (FIG. 3) of a manifold 18 (also called "tube plate" or "plate with holes") comprising at its
Dans l'exemple, les trous 16 du collecteur 18 (figure 3) ont sensiblement la forme d'ellipses dont les petits axes sont alignés et dirigés dans la direction de la rangée R des tubes. Chacun des trous 16 est entouré d'un collet 26 (figures 1 et 3).In the example, the
L'étanchéité au niveau des extrémités 25 des tubes 12 est assurée par une feuille d'élastomère 27 (figure 1) qui recouvre une face du collecteur 18 et qui comprend des collets (non représentés) serrés entre les extrémités des tubes 12 et les collets 26, et cela d'une manière en ellemême connue.Sealing at the
Le collecteur 18 est formé à partir d'un flan d'une tôle métallique. Le collecteur 18 proprement dit a une forme générale rectangulaire et comporte deux bords longitudinaux 30 qui forment les grands côtés du rectangle et s'étendent parallèlement à un axe XX correspondant à la direction de la rangée R et constituant en même temps un axe de symétrie.The
Par ailleurs, le collecteur 18 comprend deux extrémités longitudinales 32 qui constituent les petits côtés du rectangle. Les pattes de sertissage 20 sont formées essentiellement le long de chacun des bords longitudinaux 30.Furthermore, the
Le collecteur 18 comprend en outre une patte de sertissage 34 formée par un crevé de la tôle au niveau de chacune des extrémités longitudinales 32 (figures 1 à 3).The
Les pattes de sertissage 20 et les pattes de sertissage 34 sont propres à être rabattues contre le bord périphérique 22 de la boîte à eau 24, et cela d'une manière en soi connue.The
Selon l'invention, le collecteur 18 est formé d'une seule pièce avec deux pattes d'immobilisation 36 formées dans le flan de tôle et rattachées au collecteur 18 proprement dit au niveau de ses deux extrémités longitudinales 32.According to the invention, the
Chacune des pattes d'immobilisation 36 a une forme générale rectangulaire et est rattachée à l'extrémité 32 correspondante par une languette 38 de forme générale rectangulaire, qui est limitée par deux côtés 40 (figure 2) s'étendant parallèlement à l'axe XX.Each of the immobilizing
La patte 36 (figure 1) est limitée par un grand côté 42 rattaché à la languette 38 et un autre grand côté 44, et par deux petits côtés 46 situés symétriquement de part et d'autre de l'axe XX.The tab 36 (Figure 1) is limited by a
Dans le côté 44 sont formées deux échancrures 48 situées symétriquement de part et d'autre de l'axe XX et dans le prolongement des côtés 40 de la languette 38 (figures 1, 2 et 4).In the
La patte 36 comporte une âme centrale 52 située dans le prolongement de la languette 38 et deux ailes latérales 54 reliées à l'âme 52.The
Les échancrures 48 permettent de faciliter le pliage de la patte 36 suivant un axe de pliage 56 perpendiculaire à l'axe XX, ce qui permet de former un bord 58 légèrement ouvert rattaché à l'âme 52 et deux bords 60 légèrement ouverts et rattachés respectivement aux deux ailes 54, comme montré aux figures 1 à 4.The
Pour assurer la fabrication d'un échangeur de chaleur selon l'invention, on part d'au moins un collecteur 18 formé par découpe d'une tôle métallique. Cette dernière est ensuite emboutie de manière à constituer une gorge périphérique (non représenée) propre à recevoir ultérieurement le rebord périphérique 22 de la boîte à eau 24. On procède également au pliage à angle droit des deux ailes 54 par rapport à l'âme 52, ce qui permet de fournir une patte repliée à section en U comme représenté aux figures 1 et 2.To ensure the manufacture of a heat exchanger according to the invention, one starts from at least one
Il est à noter que le bord 58 et les deux bords 60 ont avantageusement été pliés le long de l'axe 56 préalablement au pliage des deux ailes 54.It should be noted that the
Comme on le voit sur la figure 4, la languette 38 comprend un décrochement formé par deux lignes de pliage adjacentes 62 qui s'étendent parallèlement entre elles et perpendiculairement à la direction XX.As seen in Figure 4, the
Ce décrochement permet à la languette 38 et à l'âme 52 de contourner l'extrémité longitudinale 32 du collecteur 18 de manière à venir au plus près des ailettes 14.This recess allows the
Il suffit ensuite de replier chacune des pattes 36 autour d'un axe 64 qui s'étend perpendiculairement à l'axe XX et qui constitue la liaison entre l'extrémité 32 du collecteur et la languette 38 correspondante.It then suffices to fold each of the
On fait alors pivoter la patte d'immobilisation 36 d'environ 90°. Ensuite, le collecteur 18 est assemblé de façon classique au faisceau 10 puis à la boîte à eau 34.The
La position ainsi obtenue correspond à celle qui est montrée aux figures 1 à 3 et dans laquelle chacune des pattes d'immobilisation 36 s'étend parallèlement à la direction des tubes 12 de manière à prendre appui contre les bords d'un certain nombre d'ailettes 14 du faisceau.The position thus obtained corresponds to that which is shown in FIGS. 1 to 3 and in which each of the immobilizing
Dans la position ainsi représentée, la patte repliée 36, par sa forme en U, vient coiffer une extrémité longitudinale du faisceau, l'âme 52 venant prendre appui contre une face d'extrémité dudit faisceau et les deux ailes 54 venant prendre appui contre deux faces longitudinales du faisceau.In the position thus represented, the folded
Il en résulte que le faisceau de tubes est parfaitement immobilisé à l'égard de tous mouvements de pivotement ou de torsion par rapport à l'ensemble collecteur-boîte à eau.As a result, the bundle of tubes is perfectly immobilized with respect to any pivoting or torsional movements relative to the manifold-water box assembly.
Les différentes opérations de fabrication d'un échangeur de chaleur selon l'invention sont sensiblement identiques à celles d'un échangeur de chaleur de la technique antérieure.The various manufacturing operations of a heat exchanger according to the invention are substantially identical to those of a heat exchanger of the prior art.
Il suffit simplement de prévoir un collecteur spécifique formé à partir d'un flan de tôle métallique auquel on fait subir un certain nombre d'opérations mécaniques de découpage, emboutissage et pliage.It suffices simply to provide a specific collector formed from a sheet of metal sheet which is subjected to a certain number of mechanical cutting, stamping and folding operations.
Du fait que le faisceau est parfaitement immobilisé par rapport à l'ensemble collecteur-boîte à eau, on garantit ainsi un maintien d'une étanchéité parfaite au niveau des extrémités des tubes engagées dans les trous du collecteur.Because the beam is perfectly immobilized relative to the collector-water box assembly, this guarantees a perfect seal is maintained at the ends of the tubes engaged in the holes in the collector.
