Abstract
Description
L'invention se rapporte aux échangeurs de chaleur, notamment pour véhicule automobile.The invention relates to heat exchangers, in particular for motor vehicle.
Elle concerne tout particulièrement un échangeur de chaleur du type comprenant un faisceau de tubes à ailettes et un collecteur qui présente une âme centrale, dans laquelle est aménagée au moins une rangée de trous bordés par des collets pour la réception des tubes du faisceau, et une gorge périphérique raccordée à l'âme centrale par un bord replié.It particularly relates to a heat exchanger of the type comprising a bundle of finned tubes and a collector which has a central core, in which is fitted with at least one row of holes bordered by collars for receiving beam tubes, and a groove peripheral connected to the central core by a folded edge.
Les échangeurs de chaleur de ce type sont utilisés dans les véhicules automobiles, notamment pour constituer un radiateur de refroidissement du moteur ou un radiateur du chauffage de l'habitacle.Heat exchangers of this type are used in motor vehicles, in particular for constituting a radiator engine cooling or heating radiator the passenger compartment.
De tels échangeurs de chaleur peuvent être réalisés sous la forme de deux types principaux que l'on appelle respectivement échangeurs du type à assemblage mécanique et échangeurs du type brasé.Such heat exchangers can be produced under the form of two main types called respectively heat exchangers of the mechanical assembly type and heat exchangers of the brazed type.
Dans les échangeurs à assemblage mécanique, les extrémités des tubes sont reçus dans les collets de la plaque collectrice avec insertion de manchons correspondants faisant partie d'un joint d'étanchéité. Ces manchons du joint d'étanchéité sont comprimés par évasement des tubes, ce qui procure une étanchéité.In mechanically assembled exchangers, the ends tubes are received in the collars of the collector plate with insertion of corresponding sleeves making part of a seal. These seal sleeves are compressed by flaring the tubes, which provides a seal.
Dans les échangeurs de chaleur brasés, les extrémités des tubes sont reçues directement dans les collets de la plaque collectrice et sont brasés à cette dernière.In brazed heat exchangers, the ends of the tubes are received directly in the plate collars collector and are soldered to the latter.
La gorge périphérique qui entoure l'âme centrale du collecteur est raccordée à cette âme centrale par un bord replié qui est généralement réalisé sous la forme d'un bord sensiblement droit qui se raccorde perpendiculairement à l'âme centrale.The peripheral groove which surrounds the central core of the collector is connected to this central core by a folded edge which is generally made in the form of a substantially edge straight which connects perpendicular to the core central.
La gorge périphérique est destinée à recevoir le pourtour, encore appelé pied, d'une boíte collectrice. Cette dernière délimite avec le collecteur un volume qui est en communication avec les tubes du faisceau.The peripheral groove is intended to receive the periphery, also called foot, from a manifold. This last delimits with the collector a volume which is in communication with the bundle tubes.
Dans le cas des échangeurs de chaleur à assemblage mécanique, le pied de la boíte collectrice assure la compression d'une région périphérique du joint d'étanchéité qui est reçue dans la gorge périphérique. Cette compression est obtenue habituellement par des moyens de sertissage, ce qui garantit une étanchéité.In the case of mechanically assembled heat exchangers, the base of the manifold ensures compression of a peripheral region of the seal which is received in the peripheral throat. This compression is usually obtained by crimping means, which guarantees a sealing.
Dans le cas des échangeurs de chaleur brasés, la gorge périphérique reçoit également le pourtour de la boíte collectrice pour assurer une liaison par brasage.In the case of brazed heat exchangers, the groove device also receives the periphery of the box collector to ensure a connection by brazing.
Dans la plupart des collecteurs connus de ce genre, le bord replié ainsi que les collets s'étendent généralement d'un même côté de l'âme centrale et, jusqu'à présent, la région des collets, qui se trouve la plus proche du bord replié, est à une distance qui, habituellement, ne peut descendre en dessous d'une valeur de l'ordre de 1mm.In most known collectors of this kind, the edge folded back so that the collars generally extend from a same side of the central soul and, so far, the region collars, which is closest to the folded edge, is at a distance which usually cannot go down below a value of the order of 1mm.
Dans ces conditions, il existe un espace mort entre les collets et le bord replié.Under these conditions, there is a dead space between the collars and the folded edge.
Habituellement, ce bord replié présente un contour de forme générale rectangulaire et il présente notamment deux tronçons longitudinaux qui s'étendent parallèlement aux grands côtés du collecteur et également parallèlement à la (aux) rangée(s) des tubes.Usually this folded edge has a contoured shape general rectangular and in particular it has two sections longitudinal which extend parallel to the long sides of the collector and also parallel to the row (s) tubes.
Ainsi, dans le cas d'un échangeur de chaleur à une seule rangée de tubes, encore appelé échangeur mono-rang, les deux tronçons du bord replié sont toujours à une distance non négligeable des collets, ce qui augmente indûment la distance entre les deux tronçons et, par conséquent, la largeur du collecteur.So, in the case of a single heat exchanger row of tubes, also called single-row exchanger, both sections of the folded edge are always at a distance not negligible snares, which unduly increases the distance between the two sections and, therefore, the width of the collector.
L'invention a notamment pour but de surmonter cet inconvénient.The object of the invention is in particular to overcome this drawback.
Elle propose à cet effet un échangeur de chaleur du type défini précédemment, dans lequel chaque collet est sensiblement au contact dudit bord replié de manière à définir entre eux un jeu d'une valeur minimale.To this end, it offers a heat exchanger of the type defined above, in which each collar is substantially in contact with said folded edge so as to define between them a game of minimal value.
La Demanderesse a constaté que, moyennant un procédé de fabrication particulier, qui peut par exemple utiliser des poinçons de matriçage, il est possible de faire en sorte que chaque collet vienne sensiblement au contact du bord replié, ce qui permet de définir un jeu d'une valeur minimale, voire nulle.The Applicant has found that, by means of a process of particular manufacturing, which can for example use stamping punches it is possible to make that each collar comes substantially into contact with the folded edge, which makes it possible to define a set of a minimum value, even nothing.
Ainsi, la valeur de ce jeu est avantageusement comprise entre 0 et 1mm.Thus, the value of this game is advantageously between 0 and 1mm.
Il en résulte que la gorge périphérique entoure plus étroitement l'âme centrale du collecteur, ce qui permet de diminuer notablement l'encombrement.As a result, the peripheral throat surrounds more tightly the central core of the collector, which reduces notably the size.
Ceci constitue un avantage conséquent lorsque l'on sait que la place dévolue aux équipements des véhicules automobiles, en particulier dans le compartiment moteur, est de plus en plus réduite.This is a significant advantage when you know that the space allocated to motor vehicle equipment, especially in the engine compartment, is increasingly more reduced.
Les collets sont avantageusement réalisés au moyen de poinçons de matriçage.The collars are advantageously made by means of stamping punches.
Selon l'invention, les extrémités des tubes peuvent être soit reçues dans les collets avec interposition d'un joint d'étanchéité, soit être brasées dans les collets.According to the invention, the ends of the tubes can be either received in the collars with interposition of a seal, either be brazed in the collars.
L'invention s'applique pour différentes formes de collets et d'extrémités des tubes. The invention applies to different forms of collars and tube ends.
Ainsi, les collets et les extrémités des tubes peuvent notamment avoir une forme générale circulaire, ou encore une forme générale oblongue, en particulier ovale ou elliptique.Thus, the collars and the ends of the tubes can in particular have a generally circular shape, or else a generally oblong shape, in particular oval or elliptical.
Selon une autre caractéristique de l'invention, une ailette est en contact avec le collecteur dans la région de la gorge périphérique. Ceci permet de réaliser une fonction de protection vis-à-vis de la corrosion.According to another characteristic of the invention, a fin is in contact with the collector in the throat region peripheral. This makes it possible to carry out a function of protection against corrosion.
Dans la description qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :
- la figure 1 est une vue en coupe transversale d'un collecteur d'un échangeur de chaleur selon l'invention;
- la figure 2 est une vue partielle de dessus correspondant à la figure 1;
- la figure 3 est un détail à échelle agrandie de la figure 1; et
- la figure 4 est une vue en coupe analogue à la figure 1 après assemblage d'un faisceau de tubes et d'une boíte collectrice pour former un échangeur de chaleur.
- Figure 1 is a cross-sectional view of a manifold of a heat exchanger according to the invention;
- Figure 2 is a partial top view corresponding to Figure 1;
- Figure 3 is an enlarged detail of Figure 1; and
- Figure 4 is a sectional view similar to Figure 1 after assembly of a bundle of tubes and a manifold to form a heat exchanger.
On se réfère d'abord aux figures 1 et 2 qui montrent un
collecteur 10 propre à faire partie d'un échangeur de
chaleur, notamment pour un véhicule automobile. Cet échangeur
de chaleur peut constituer, par exemple, un radiateur de
refroidissement du moteur ou un radiateur de chauffage de
l'habitacle.We first refer to Figures 1 and 2 which show a
Le collecteur 10 est réalisé par emboutissage et matriçage
d'une plaque métallique qui est avantageusement à base
d'aluminium. Ce collecteur comprend une âme centrale plane
12, de forme générale rectangulaire, dans laquelle est
aménagée une série de trous 14 de forme oblongue, ici de
forme sensiblement elliptique, qui sont disposés suivant une
rangée R d'axe XX. Dans l'exemple, la plus grande dimension
des collets (qui correspond au grand axe AA de l'ellipse)
s'étend perpendiculairement à la direction XX précitée
(figure 2).The
Chacun des trous 14 est entouré par un collet 16 qui a la
forme générale d'un cylindre de section elliptique.Each of the
L'âme 12 est entourée par une gorge périphérique 18 qui se
raccorde à l'âme centrale par un bord replié 20. Ce bord
replié se raccorde perpendiculairement à l'âme centrale 12
puis il se raccorde ensuite, par un arrondi, à une paroi de
fond 22, laquelle s'étend parallèlement à l'âme 12. Cette
paroi de fond 22 est reliée perpendiculairement à un bord
externe 24 qui constitue, à son extrémité libre, un bord
crénelé définissant une série de dents ou pattes de sertissage
26.The
Comme on peut le voir plus particulièrement sur le détail de
la figure 3, le bord replié 20 se raccorde au collet 16 par
un pliage 28 en U qui est réalisé de telle sorte qu'une
région d'extrémité du collet 16 est pratiquement au contact
du bord replié 20. Il existe entre eux un jeu d'une valeur d
qui est minimale. Grâce à des opérations utilisant des
poinçons de matriçage, on peut s'arranger pour que le collet
16 et le bord replié 20 viennent au contact l'un de l'autre
ou sensiblement au contact l'un de l'autre. I1 en résulte
que, de manière habituelle, cette valeur d peut atteindre une
valeur très faible qui est typiquement comprise entre 0 et
1mm.As we can see more specifically on the detail of
Figure 3, the folded
Comme on peut le voir en particulier sur la figure 2, le bord
replié 20 comprend deux tronçons principaux 20a et 20b qui
sont parallèles entre eux et qui sont également parallèles à
la direction XX de la rangée. Ces deux bords viennent ainsi
en contact respectivement avec des régions d'extrémités 16a
et 16b de chacun des collets 16.As can be seen in particular in Figure 2, the edge
folded 20 comprises two
De ce fait, il est possible de faire en sorte que la largeur
L (figure 1) entre les deux tronçons 20a et 20b soit aussi
faible que possible. En effet, cette valeur L est sensiblement
égale à la dimension intérieure (grand axe AA) du collet
(figure 2) plus quatre fois l'épaisseur de la feuille
métallique dont est formé le collecteur.Therefore, it is possible to make the width
L (Figure 1) between the two
Cela permet ainsi de réaliser un collecteur dont la largeur globale est nettement plus faible que dans la technique antérieure.This thus makes it possible to produce a collector whose width overall is significantly lower than in the technique anterior.
On relèvera que, dans la technique antérieure, l'espace
compris entre le collet et le bord replié 20 était habituellement
d'au moins 1mm.It will be noted that, in the prior art, the space
between the collar and the folded
Ce collecteur est destiné à constituer un échangeur de chaleur représenté partiellement sur la figure 4.This collector is intended to constitute a heat exchanger heat partially shown in Figure 4.
Dans chacun des collets 16 est introduite l'extrémité 30 d'un
tube 32 qui fait partie d'un faisceau de tubes et d'ailettes
planes 34, lesquelles sont traversées par les tubes.In each of the
Dans l'exemple de la figure 4, les extrémités des tubes sont
rassemblées mécaniquement au collecteur par l'intermédiaire
d'un joint d'étanchéité 36 qui s'applique sur le dessus du
collecteur et qui comprend une série de manchons 38 dont
chacun est comprimé entre un collet et une extrémité 30 d'un
tube. Ce joint 36 se poursuit par une bordure périphérique 40
qui se loge dans la gorge périphérique 18. Ce pourtour est
comprimé par le pied 42 d'une boíte collectrice 44. Les
pattes 26 sont destinées à être repliées pour assurer la
compression du joint d'étanchéité dans la région de la gorge
18.In the example of Figure 4, the ends of the tubes are
mechanically collected at the collector via
a
Il s'agit ici d'un assemblage du type mécanique dont la technique de réalisation est largement connue dans le domaine.This is a mechanical type assembly whose realization technique is widely known in the field.
En variante, il est possible aussi de réaliser un assemblage
brasé dans lequel les extrémités 30 des tubes sont brasées
directement dans les collets 16. As a variant, it is also possible to carry out an assembly
brazed in which the
En ce cas, la gorge périphérique 18 peut avoir une forme
différente et reçoit généralement le pied de la boíte
collectrice et ce dernier est alors solidarisé par brasage.In this case, the
Il est à noter qu'une des ailettes 34 du faisceau vient
directement en contact avec la paroi de fond 22 du collecteur
10 dans la région de la gorge périphérique 18, ce qui
contribue à la résistance à la corrosion de l'échangeur de
chaleur.It should be noted that one of the
Bien entendu, l'invention n'est pas limitée à la forme de réalisation décrite précédemment à titre d'exemple.Of course, the invention is not limited to the form of embodiment described previously by way of example.
En particulier, l'invention peut s'appliquer à des échangeurs de chaleur comportant une ou plusieurs rangées de tubes. En outre, les extrémités des tubes, ainsi que les collets correspondants, peuvent avoir différentes formes, en particulier une forme circulaire, une forme oblongue, telle qu'une forme ovale ou elliptique, etc.In particular, the invention can be applied to exchangers heat comprising one or more rows of tubes. In in addition, the ends of the tubes, as well as the collars correspondents, can have different forms, in particular a circular shape, an oblong shape, such as a oval or elliptical shape, etc.
Egalement, il est possible de faire en sorte que le collet s'étende de l'autre côté de l'âme centrale, c'est-à-dire du côté où se situe la boíte collectrice.Also, it is possible to have the collar extends on the other side of the central core, i.e. side where the manifold is located.
L'invention trouve une application particulière aux échangeurs de chaleur pour les véhicules automobiles. Elle permet de réaliser des échangeurs de chaleur dont le collecteur possède un encombrement réduit, toutes choses égales par ailleurs, par rapport aux échangeurs de la technique antérieure, ce qui facilite leur implantation dans les véhicules automobiles.The invention finds particular application to exchangers heat for motor vehicles. She permits to produce heat exchangers including the collector has a small footprint, all other things being equal elsewhere, compared to the exchangers of the prior art, which facilitates their installation in vehicles automobiles.
