Des échangeurs de chaleur de ce type sont utilisés notamment dans les véhicules automobiles à moteur thermique pour constituer soit un radiateur de refroidissement du moteur, Heat exchangers of this type are used in particular in motor vehicles with an internal combustion engine to constitute either an engine cooling radiator,
soit un radiateur de chauffage de l'habitacle. or a radiator for heating the passenger compartment.
Les deux compartiments ménagés à l'intérieur de la boîte à eau servent, l'un à l'entrée, et l'autre à la sortie d'un fluide de refroidissement, généralement de l'eau additionnée d'un antigel, qui circule en circuit fermé et qui est refroidi par échange thermique avec un flux d'air balayant The two compartments inside the water box are used, one at the inlet, and the other at the outlet of a cooling fluid, generally water with antifreeze, which circulates in a closed circuit and which is cooled by heat exchange with a sweeping air flow

Les tubes sont reliés entre eux, à l'autre extrémité du faisceau, soit par une boîte à eau analogue, soit par des The tubes are connected to each other, at the other end of the bundle, either by a similar water box, or by
coudes.elbows.
Du fait de cet agencement, on réalise un faisceau à deux nappes ou deux passes, le fluide circulant dans un sens dans Due to this arrangement, a bundle with two layers or two passes is produced, the fluid flowing in one direction in
l'une des nappes et en sens opposé dans l'autre nappe. one of the layers and in the opposite direction in the other layer.
Habituellement, les tubes du faisceau ont une section transversale circulaire constante, tant au niveau du corps Usually the bundle tubes have a constant circular cross-section, both at body level
que de l'extrémité.that from the end.
Il est connu aussi, pour optimiser les performances de l'échangeur de chaleur, d'utiliser des tubes dont le corps possède une section transversale non circulaire de forme oblongue et dont l'extrémité possède une section transversale de forme moins oblongue, voire circulaire. Quelle que soit la forme des tubes utilisés, leurs extrémités sont reçues individuellement dans des trous qui doivent ménager entre eux un espace suffisant pour permettre le passage de la cloison longitudinale et pour conférer une It is also known, to optimize the performance of the heat exchanger, to use tubes whose body has a non-circular cross section of oblong shape and whose end has a cross section of less oblong shape, even circular. Whatever the shape of the tubes used, their ends are individually received in holes which must provide sufficient space between them to allow the passage of the longitudinal partition and to impart a
résistance mécanique élevée à la plaque collectrice. high mechanical resistance to the collector plate.
Il est donc nécessaire de prévoir un entraxe minimal entre deux trous adjacents destinés à recevoir les extrémités respectives de deux tubes adjacents appartenant à deux It is therefore necessary to provide a minimum spacing between two adjacent holes intended to receive the respective ends of two adjacent tubes belonging to two

Ceci contribue à augmenter la largeur de la plaque collec- This contributes to increasing the width of the collecting plate

Elle propose en conséquence un échangeur de chaleur du type défini en introduction, dans lequel les extrémités des tubes sont déformées et décalées par rapport au corps des tubes, en sorte que les extrémités de deux tubes adjacents appartenant à deux rangées différentes ménagent entre elles un espace pour le passage de la cloison longitudinale et que ces extrémités aient un entraxe différent de celui des corps des deny. It therefore proposes a heat exchanger of the type defined in the introduction, in which the ends of the tubes are deformed and offset relative to the body of the tubes, so that the ends of two adjacent tubes belonging to two different rows provide space between them. for the passage of the longitudinal partition and that these ends have a different center distance from that of the bodies of

Ainsi, pour un entraxe donné des corps des tubes, on peut augmenter l'espace compris entre les extrémités des tubes Thus, for a given distance between the bodies of the tubes, the space between the ends of the tubes can be increased.

Selon une autre caractéristique de l'invention, l'entraxe des extrémités des tubes adjacents est supérieur à l'entraxe des According to another characteristic of the invention, the distance between the ends of the adjacent tubes is greater than the distance between the
corps des tubes.body of the tubes.
Avantageusement, les corps des tubes ont une section trans- versale généralement aplatie, tandis que leurs extrémités ont Advantageously, the bodies of the tubes have a generally flat cross section, while their ends have

Dans une première forme de réalisation de l'invention, les extrémités respectives de deux tubes adjacents sont reçues In a first embodiment of the invention, the respective ends of two adjacent tubes are received

Dans cette forme de réalisation, l'espace ménagé entre les extrémités respectives de deux tubes adjacents est supérieur In this embodiment, the space provided between the respective ends of two adjacent tubes is greater
à l'épaisseur de la cloison.to the thickness of the partition.
De façon avantageuse, la plaque collectrice, les extrémités des tubes et la cloison sont assemblées entre elles par brasage. Il est possible également de réaliser un assemblage dit "mécanique" avec interposition d'un joint d'étanchéité entre la plaque collectrice et la cloison et entre des collets de la plaque collectrice et les tubes, bien que cet assemblage mécanique nécessite une largeur globale plus élevée que dans Advantageously, the collector plate, the ends of the tubes and the partition are joined together by brazing. It is also possible to produce a so-called "mechanical" assembly with the interposition of a seal between the manifold plate and the partition and between collars of the manifold plate and the tubes, although this mechanical assembly requires an overall width more high than in
le cas d'un assemblage par brasage.the case of an assembly by brazing.
Dans une seconde forme de réalisation de l'invention, les extrémités respectives de deux tubes adjacents sont reçues dans un même trou de la plaque collectrice, cette dernière possédant autant de trous que de paires d'extrémités de tubes. Selon une autre particularité de l'invention, les extrémités des tubes comportent deux côtés plats parallèles qui ménagent In a second embodiment of the invention, the respective ends of two adjacent tubes are received in the same hole of the collector plate, the latter having as many holes as pairs of tube ends. According to another feature of the invention, the ends of the tubes have two parallel flat sides which provide
entre eux un intervalle correspondant sensiblement à l'épais- between them an interval corresponding substantially to the thick-
seur de la cloison.sister of the partition.
Avantageusement, la cloison présente un côté longitudinal muni de dents espacées propres à venir chacune s'insérer dans un des trous de la plaque collectrice et entre les deux Advantageously, the partition has a longitudinal side provided with spaced teeth suitable for each coming to fit into one of the holes of the collector plate and between the two
extrémités des tubes, reçues dans le trou. ends of the tubes, received in the hole.
On réalise ainsi un agencement particulièrement compact en largeur. Dans cette seconde forme de réalisation de l'invention, la plaque collectrice, les extrémités des tubes et la cloison This produces a particularly compact arrangement in width. In this second embodiment of the invention, the collector plate, the ends of the tubes and the partition
longitudinale sont avantageusement assemblées par brasage. longitudinal are advantageously assembled by brazing.

The heat exchanger shown in Figures 1 to 4 comprises a plurality of tubes 10 each having a body 12 of section flattened transverse and one end 14 of section
transversale oblongue de forme sensiblement ovale (figure 3). oblong cross section of substantially oval shape (Figure 3).
Les tubes 10 sont disposés de manière à former un faisceau 16 comprenant deux rangées R1 et R2 composées, dans l'exemple, The tubes 10 are arranged so as to form a bundle 16 comprising two rows R1 and R2 composed, in the example,
de quinze tubes chacune.of fifteen tubes each.
Entre les tubes 10 sont disposées des ailettes 18 qui, dans l'exemple, ont une forme généralement ondulée. Le faisceau 16 est encadré, à ses deux extrémités, par deux traverses 20 (figure 1) qui s'étendent parallèlement à la direction des Between the tubes 10 are arranged fins 18 which, in the example, have a generally wavy shape.

Dans l'exemple, la plaque collectrice 22 comporte quinze paires de trous 26 en trice 22 having a multiplicity of collars 24 each delimiting a hole 26 of substantially oval shape serving for the passage of one end 14 of a tube 10. In the example, the collector plate 22 comprises fifteen pairs of holes 26 in

Entre la plaque collectrice 22 et la paroi 32 est disposée Between the collecting plate 22 and the wall 32 is disposed

ments: un compartiment d'entrée 36 communiquant avec les tubes de la rangée R1 et un compartiment de sortie 38 communiquant avec les tubes de la rangée R2 (figure 2). Sur la paroi 32 est montée une embase 40 comportant une tubulure d'entrée 42 et une tubulure de sortie 44 communiquant elements: an inlet compartment 36 communicating with the tubes of row R1 and an outlet compartment 38 communicating with the tubes of row R2 (Figure 2). On the wall 32 is mounted a base 40 comprising an inlet pipe 42 and an outlet pipe 44 communicating
respectivement avec les compartiments 36 et 38. respectively with compartments 36 and 38.
A leur autre extrémité, les tubes 10 du faisceau communiquent entre eux par des moyens (non représentés) pouvant consister, At their other end, the tubes 10 of the bundle communicate with each other by means (not shown) which may consist,
soit en une boîte à eau similaire, soit en des coudes. either in a similar water box or in elbows.
L'échangeur de chaleur peut être ainsi traversé par un fluide, par exemple de l'eau additionnée d'un antigel, qui pénètre dans le compartiment 36 par l'entrée 42, parcourt ensuite une première nappe constituée par les tubes de la rangée R1, puis une seconde nappe constituée par les tubes de la rangée R2 pour gagner le compartiment 38 et quitter The heat exchanger can thus be traversed by a fluid, for example water added with an antifreeze, which enters the compartment 36 through the inlet 42, then travels through a first layer constituted by the tubes of row R1 , then a second layer made up of the tubes of row R2 to reach compartment 38 and leave
l'échangeur de chaleur par la tubulure 44. the heat exchanger through the pipe 44.
Comme on peut le voir plus particulièrement sur les figures 2 et 3, les extrémités 14 des tubes 10 sont déformées et décalées par rapport au corps 12 des tubes, en sorte que les extrémités 14 de deux tubes adjacents appartenant aux deux As can be seen more particularly in FIGS. 2 and 3, the ends 14 of the tubes 10 are deformed and offset relative to the body 12 of the tubes, so that the ends 14 of two adjacent tubes belonging to the two
rangées différentes R1 et R2 ménagent entre elles un inter- different rows R1 and R2 provide an inter-
valle de passage P pour la cloison longitudinale 34. passage valleys P for the longitudinal partition 34.
En outre, les extrémités 14 ont un entraxe terminal El In addition, the ends 14 have a terminal center distance El
différent de l'entraxe central E2 des corps 12 des tubes. different from the central distance E2 of the bodies 12 of the tubes.
Dans l'exemple, l'entraxe terminal El est supérieur à In the example, the terminal spacing El is greater than
l'entraxe central E2.the center distance E2.
Il est à remarquer que les corps respectifs 12 de deux tubes adjacents (appartenant à deux rangées différentes) sont sensiblement en contact entre eux, tandis que l'intervalle de passage P ménagé entre les extrémités 14 de deux tubes It should be noted that the respective bodies 12 of two adjacent tubes (belonging to two different rows) are substantially in contact with each other, while the passage interval P formed between the ends 14 of two tubes
adjacents est supérieur à l'épaisseur de la cloison 34. adjacent is greater than the thickness of the partition 34.
Ceci permet de minimiser l'encombrement en largeur de l'échangeur de chaleur tout en ménageant un intervalle de passage P suffisant pour la mise en place de la cloison et pour conférer une résistance mécanique élevée à la plaque This makes it possible to minimize the space requirement in width of the heat exchanger while providing a passage interval P sufficient for the installation of the partition and to impart high mechanical resistance to the plate.

Dans la forme de réalisation des figures 1 à 4, la plaque collectrice 22, les extrémités 14 des tubes et la cloison 34 In the embodiment of Figures 1 to 4, the header plate 22, the ends 14 of the tubes and the partition 34
sont de préférence assemblées entre elles par brasage. are preferably joined together by brazing.

On se réfère maintenant aux figures 5 à 9 qui représentent une autre forme de réalisation de l'invention s'apparentant à celle des figures 1 à 4. Les éléments similaires ou Reference is now made to FIGS. 5 to 9 which represent another embodiment of the invention similar to that of FIGS. 1 to 4. Similar elements or
identiques sont désignés par les mêmes références numériques. identical are designated by the same reference numerals.
L'échangeur de chaleur comprend une multiplicité de tubes 10 présentant chacun un corps 12 de section transversale aplatie et une extrémité 14 de section oblongue et disposés pour fermer un faisceau 16 à deux rangées R1 et R2. Des ailettes The heat exchanger comprises a multiplicity of tubes 10 each having a body 12 of flattened cross section and one end 14 of oblong section and arranged to close a bundle 16 with two rows R1 and R2. Fins
18 de forme ondulée sont disposées entre les tubes 10. 18 of corrugated shape are arranged between the tubes 10.
L'échangeur de chaleur comprend en outre une plaque collec- The heat exchanger further includes a collecting plate
trice 22 munie d'une seule rangée de trous 26 de forme générale allongée (figure 7), chaque trou étant destiné à recevoir en même temps les extrémités respectives 14 de deux trice 22 provided with a single row of holes 26 of generally elongated shape (Figure 7), each hole being intended to receive at the same time the respective ends 14 of two
tubes adjacents 10.adjacent tubes 10.
Chacun des trous 26 est bordé par un collet 24 et délimité par deux bords longitudinaux parallèles 50 et par deux bords Each of the holes 26 is bordered by a collar 24 and delimited by two parallel longitudinal edges 50 and by two edges
semi-circulaires 52 (figure 7).semicircular 52 (Figure 7).
Chacune des extrémités 14 est délimitée par deux côtés longitudinaux parallèles 54, un côté semi-circulaire 56 et un côté transversal droit et plat 58. Les deux côtés 58 sont disposés parallèlement en vis-à-vis (figure 8) et ménagent Each of the ends 14 is delimited by two parallel longitudinal sides 54, a semi-circular side 56 and a straight and flat transverse side 58. The two sides 58 are arranged parallel opposite (FIG. 8) and provide
entre eux un intervalle de passage P' correspondant sensible- between them a corresponding corresponding passage interval P '
ment à l'épaisseur de la cloison 34. Lorsque les deux extrémités 14 adjacentes sont introduites dans le trou 26, les côtés 44 viennent coopérer avec les côtés 50 du trou, tandis que les côtés 56 viennent coopérer avec les côtés 52 du trou. On peut alors placer la cloison longitudinale 34 dans chacun des espaces P' ménagés par chacune des paires de tubes. Comme dans la forme de réalisation précédente, les extrémités 14 présentent un entraxe El supérieur à l'entraxe E2 des corps 12, lesquels viennent sensiblement en contact entre eux. (Figures 5 et 6 à modifier) La cloison 34 a sensiblement la forme d'un peigne possédant un côté longitudinal 60 (figure 9) muni de dents espacées 62 propres à venir chacune s'insérer dans un trou 26 de la plaque collectrice 22 et dans l'intervalle P' compris entre ment to the thickness of the partition 34. When the two adjacent ends 14 are introduced into the hole 26, the sides 44 come to cooperate with the sides 50 of the hole, while the sides 56 come to cooperate with the sides 52 of the hole. One can then place the longitudinal partition 34 in each of the spaces P 'formed by each of the pairs of tubes. As in the previous embodiment, the ends 14 have a center distance El greater than the center distance E2 of the bodies 12, which come substantially into contact with one another. (Figures 5 and 6 to be modified) The partition 34 has substantially the shape of a comb having a longitudinal side 60 (Figure 9) provided with spaced teeth 62 suitable for each coming to be inserted in a hole 26 of the collector plate 22 and in the interval P 'between
les deux extrémités 14 reçues dans le trou 26. the two ends 14 received in the hole 26.
