Description
VTM1577.FRD Echangeur de chaleur à collecteur amélioréVTM1577.FRD Enhanced Collector Heat Exchanger
L'invention concerne un échangeur de chaleur, en particulier pour des véhicules automobiles. The invention relates to a heat exchanger, in particular for motor vehicles.
Les échangeurs de chaleur comportent généralement un collecteur relié à un faisceau de tubes. Classiquement, ce collec- teur peut-être formé par une plaque collectrice recouverte d'un couvercle. Heat exchangers generally include a collector connected to a bundle of tubes. Conventionally, this collector may be formed by a collector plate covered with a lid.
L'invention concerne plus particulièrement un échangeur de chaleur comportant une plaque collectrice ayant une âme percée de trous pour recevoir les tubes d'un faisceau, les trous étant entourés chacun d'un collet présentant deux paires de côtés opposées, et dans lequel la plaque collectrice comporte un bord relevé à sa périphérie. The invention more particularly relates to a heat exchanger comprising a header plate having a core pierced with holes for receiving the tubes of a bundle, the holes being each surrounded by a collar having two pairs of opposite sides, and in which the plate collector has a raised edge at its periphery.
De tels échangeurs de chaleur sont réalisés de manières diverses. Ainsi, le bord relevé de la plaque collectrice peut former une gorge pour recevoir un couvercle en matière plastique serti dans celle-ci. Such heat exchangers are made in various ways. Thus, the raised edge of the header plate can form a groove for receiving a plastic cover crimped therein.
Un tel échangeur de chaleur peut également recevoir un couvercle en métal, par exemple en aluminium, brasé sur le bord périphérique de la plaque collectrice. Such a heat exchanger can also receive a metal cover, for example aluminum, brazed to the peripheral edge of the collector plate.
D'une manière classique, les plaques collectrices de ces échangeurs de chaleur présentent des collets qui sont en général formés par poinçonnage et relevage ou crevage de la plaque. Les tubes sont insérés dans ces collets et l'ensemble brasé pour former l'échangeur de chaleur. In a conventional manner, the collector plates of these heat exchangers have collars which are generally formed by punching and lifting or puncturing the plate. The tubes are inserted into these collars and the brazed assembly to form the heat exchanger.
L'utilisation de tels collets peut constituer un inconvénient dans certains cas. En effet, afin de réduire l'encombrement, la largeur de la plaque collectrice est souvent définie par la largeur des tubes ajoutée de l'épaisseur des collets. Ces derniers représentent un encombrement non négligeable. The use of such collars may be a disadvantage in some cases. Indeed, to reduce clutter, the width of the header plate is often defined by the width of the tubes added to the thickness of the collars. These last represent a not insignificant bulk.
D'autre part, il est classique d'utiliser des tubes présentant une épaisseur relativement limitée, dits "plats". La tenue mécanique des échangeurs les comportant est celle de l'ensemble formé par le tube et le collet du trou qui le reçoit, une fois le brasage réalisé. La faible épaisseur de ces tubes constitue donc une faiblesse de l'ensemble. On the other hand, it is conventional to use tubes having a relatively limited thickness, called "flat". The mechanical strength of the exchangers comprising them is that of the assembly formed by the tube and the collar of the hole which receives it, once the brazing is done. The small thickness of these tubes is therefore a weakness of the whole.
L'invention se propose d'améliorer la situation. The invention proposes to improve the situation.
A cet effet, il est proposé un échangeur de chaleur comportant une plaque collectrice ayant une âme percée de trous pour recevoir des tubes d'un faisceau, les trous étant entourés chacun d'un collet présentant deux paires de côtés opposés, et dans lequel la plaque collectrice comporte un bord relevé à sa périphérie. Dans cet échangeur de chaleur, au moins un premier côté d'un collet est formé directement par le bord relevé, tandis qu'au moins un second côté dudit collet est issu de l'âme de la plaque collectrice. For this purpose, there is provided a heat exchanger comprising a header plate having a core pierced with holes for receiving tubes from a bundle, the holes being each surrounded by a collar having two pairs of opposite sides, and in which the collector plate has a raised edge at its periphery. In this heat exchanger, at least one first side of a collar is formed directly by the raised edge, while at least one second side of said collar is derived from the core of the header plate.
Ce type d'échangeur de chaleur est extrêmement avantageux en ce qu'il utilise le bord relevé de la plaque collectrice pour former un côté d'un collet entourant un trou recevant un tube. Ainsi, la place occupée normalement par ce collet est économisée. De ce fait, on peut soit diminuer l'encombrement de l'échangeur de chaleur, soit augmenter les performances de l'échangeur en augmentant les dimensions des tubes. This type of heat exchanger is extremely advantageous in that it uses the raised edge of the header plate to form a side of a collar surrounding a hole receiving a tube. Thus, the place normally occupied by this collar is saved. Therefore, one can either reduce the size of the heat exchanger, or increase the performance of the exchanger by increasing the dimensions of the tubes.
Avantageusement, une fois l'échangeur assemblé, le second côté est brasé au premier côté. Advantageously, once the heat exchanger is assembled, the second side is soldered to the first side.
Ce type d'échangeur de chaleur est extrêmement intéressant en ce qu'il offre une tenue mécanique améliorée. En effet, le brasage d'un côté du collet sur le bord relevé permet, une fois que l'échangeur a été brasé, de répartir les efforts exercés sur le tube non seulement sur le collet mais aussi sur l'ensemble de la plaque collectrice. This type of heat exchanger is extremely interesting in that it offers improved mechanical strength. Indeed, the brazing of one side of the collar on the raised edge allows, once the exchanger has been soldered, to distribute the forces exerted on the tube not only on the collar but also on the whole of the collector plate .
Dans un mode de réalisation le faisceau comporte une rangée de tubes, et chaque collet comporte une paire de premier côtés opposés l'un à l'autre. In one embodiment, the bundle includes a row of tubes, and each collar has a pair of opposite first sides to each other.
Dans un autre mode de réalisation le faisceau comporte deux rangées de tubes, et chaque collet comporte un premier côté et un second côté qui lui est opposé. In another embodiment, the bundle comprises two rows of tubes, and each collar has a first side and a second opposite side.
Les second côtés du collet, issus de l'âme, peuvent s'étendre 10 vers l'intérieur du collecteur ou vers l'extérieur du collecteur, c'est-à-dire vers le faisceau de tubes. The second sides of the collar, originating from the core, may extend inwardly of the manifold or outwardly of the manifold, that is, towards the bundle of tubes.
Le bord relevé de la plaque collectrice peut former une gorge propre à recevoir un joint d'étanchéité ainsi qu'un couvercle en plastique sertissable. Le bord relevé peut également être propre à recevoir un couvercle auquel il peut être brasé. The raised edge of the header plate can form a clean groove for receiving a seal and a crimpable plastic cover. The raised edge can also be adapted to receive a lid to which it can be brazed.
D'autres avantages et caractéristiques de l'invention apparaîtront mieux à la lecture de la description qui suit d'exemples donnés à titre illustratif et non limitatif issus des dessins sur lesquels: - la figure 1 représente une vue de dessus d'une plaque collectrice d'un échangeur de chaleur selon l'invention; - la figure 2 représente une vue en coupe selon l'axe II-II de la figure 1, dans laquelle un couvercle recouvre la plaque collectrice et un tube est reçu dans un trou qu'elle comporte; -la figure 3 représente une vue en coupe selon l'axe III-III de la figure 1, dans laquelle un couvercle recouvre la plaque collectrice et un tube est reçu dans un trou qu'elle comporte; - la figure 4 représente une vue de dessus d'un deuxième mode de réalisation dans lequel la plaque collectrice reçoit deux rangées de tubes; - la figure 5 représente une variante de la figure 4; et - la figure 6 représente une vue en coupe partielle d'un détail VI de la figure 4. Other advantages and features of the invention will appear better on reading the following description of examples given by way of non-limiting illustration from the drawings in which: - Figure 1 shows a top view of a header plate a heat exchanger according to the invention; - Figure 2 shows a sectional view along the axis II-II of Figure 1, wherein a cover covers the collector plate and a tube is received in a hole that it comprises; FIG 3 is a sectional view along the axis III-III of Figure 1, wherein a cover covers the collector plate and a tube is received in a hole that it comprises; FIG. 4 represents a view from above of a second embodiment in which the collector plate receives two rows of tubes; FIG. 5 represents a variant of FIG. 4; and FIG. 6 represents a partial sectional view of a detail VI of FIG. 4.
Comme représenté sur la figure 1, une plaque collectrice 2 d'un échangeur de chaleur comporte une âme 4 de forme générale rectangulaire, percée de trous 6 de forme générale rectangulaire bordés par des collets 8. L'âme 4 est métal- lique et formée par exemple d'un alliage d'aluminium. As shown in FIG. 1, a collector plate 2 of a heat exchanger comprises a core 4 of generally rectangular shape, pierced with holes 6 of generally rectangular shape bordered by flanges 8. The core 4 is metal and formed for example an aluminum alloy.
Les trous 6 ont des dimensions leur permettant de recevoir les tubes du faisceau de l'échangeur de chaleur (représentés sur les figures 2 et 3) dont fait partie la plaque 2. The holes 6 have dimensions enabling them to receive the tubes of the bundle of the heat exchanger (shown in FIGS. 2 and 3), of which the plate 2 is part.
Dans l'exemple ici décrit, ces tubes sont plats et partagent avec les trous 6 un grand axe X-X et un petit axe Y-Y. Par tube plat, on entend un tube de section de forme générale oblongue, avec deux grands côtés parallèles et deux petits côtés reliant les extrémités respectives des grands côtés. Ces tubes pourraient néanmoins être de nature différente selon l'application recherchée. In the example described here, these tubes are flat and share with the holes 6 a large axis X-X and a small axis Y-Y. By flat tube is meant a generally oblong section tube, with two large parallel sides and two small sides connecting the respective ends of the long sides. These tubes could nevertheless be different in nature depending on the application sought.
Les collets 8 comportent ici deux paires de côtés opposés respectivement 10 et 12. Ces paires de côtés s'étendent selon les axes X-X et Y-Y et correspondent respectivement à des "grands côtés" et des "petits côtés" du rectangle que forme chaque trou. The collars 8 here comprise two pairs of opposite sides respectively 10 and 12. These pairs of sides extend along the X-X and Y-Y axes and correspond respectively to "long sides" and "short sides" of the rectangle formed by each hole.
Plus précisément, une paire de côtés 10 s'étend selon l'axe X-X. Elle comporte deux côtés l0a et 10b formés par poinçon-nage et relevage ou crevage de l'âme 4. More specifically, a pair of sides 10 extends along the X-X axis. It comprises two sides 10a and 10b formed by punch-swimming and lifting or tearing of the soul 4.
L'autre paire 12 s'étend selon le petit axe Y-Y. Elle comporte deux côtés 12a et 12b formés par une portion 14 d'un bord relevé 16 de l'âme 4. Le bord relevé 16 s'étend tout le long de la périphérie de l'âme 4. The other pair 12 extends along the minor axis Y-Y. It comprises two sides 12a and 12b formed by a portion 14 of a raised edge 16 of the core 4. The raised edge 16 extends all along the periphery of the core 4.
Le collet 8 apparaîtra plus clairement à la vue des figures 2 et 3 qui représentent des coupes partielles selon des axes II et III de la figure 1. The collar 8 will appear more clearly in the view of Figures 2 and 3 which show partial sections along axes II and III of Figure 1.
Sur les figures 2 et 3, un couvercle 18 de la boîte collectrice 2 ainsi qu'un tube 20 du faisceau de l'échangeur de chaleur selon l'invention sont représentés. In Figures 2 and 3, a cover 18 of the manifold 2 and a tube 20 of the beam of the heat exchanger according to the invention are shown.
Sur la figure 2, on a représenté une coupe montrant le fond du couvercle 18, ainsi que le côté 10a de la paire 10 du collet 8. Un tube 20 pénètre un trou 6 de la plaque collectrice 2, et vient au contact de la paire de côtés 10 d'une part et de la paire de côtés 12 d'autre part. In Figure 2, there is shown a section showing the bottom of the cover 18, and the side 10a of the pair 10 of the collar 8. A tube 20 enters a hole 6 of the header plate 2, and comes into contact with the pair sides 10 on the one hand and the pair of sides 12 on the other.
Comme on le voit mieux sur cette figure, le côté 12a est formé par une portion du bord relevé 16 qui forme ici une gorge 22. As best seen in this figure, the side 12a is formed by a portion of the raised edge 16 which here forms a groove 22.
Cette gorge 22 reçoit un couvercle 18. Un joint périphéri- que 24 est entreposé entre le couvercle 18 et la gorge 22. Le couvercle 18 est ici réalisé en matière plastique, d'où la nécessité du joint 24 afin d'assurer l'étanchéité. Une extrémité 26 du bord relevé 16 peut être rabattue afin de sertir le couvercle 18. This groove 22 receives a cover 18. A peripheral seal 24 is stored between the cover 18 and the groove 22. The cover 18 is here made of plastic, hence the need for the seal 24 to ensure the seal . One end 26 of the raised edge 16 can be folded to crimp the lid 18.
Comme on peut le voir sur cette figure, les côtés 10 s'étendent vers le faisceau de tubes, depuis la plaque collectrice 2. As can be seen in this figure, the sides 10 extend towards the bundle of tubes, from the collector plate 2.
Lorsque l'échangeur est brasé, les côtés 10 sont brasés aux côtés 12 comme indiqué par une flèche 30. Ainsi, lorsque le tube 20 est brasé au collet 8, ceux-ci forment un ensemble solidaire avec le bord relevé 16, ce qui améliore la tenue mécanique de l'échangeur ainsi formé. When the exchanger is brazed, the sides 10 are brazed to the sides 12 as indicated by an arrow 30. Thus, when the tube 20 is brazed to the collar 8, these form an integral assembly with the raised edge 16, which improves the mechanical strength of the exchanger thus formed.
En outre, le côté du collet 8 selon le petit axe Y-Y étant formé par la portion 14 du bord relevé 16 de l'âme 4, un gain important de place est effectué. In addition, the side of the collar 8 along the small Y-Y axis being formed by the portion 14 of the raised edge 16 of the core 4, a significant gain of space is made.
La figure 3 montre une vue analogue à la figure 2, mais selon l'axe IIIIII, qui se situe au milieu d'un trou 6. Cette vue permet d'apprécier plus concrètement le brasage du tube au sein de l'échangeur. Figure 3 shows a view similar to Figure 2, but along the axis IIIIII, which is in the middle of a hole 6. This view allows to more concretely appreciate the brazing of the tube within the exchanger.
Ainsi, non seulement le tube 20 est brasé aux côtés 10, mais il est également brasé à la portion 14, en plus des côtés 10 qui sont également brasés à la portion 14. Thus, not only is the tube 20 brazed at the sides 10, but it is also soldered to the portion 14, in addition to the sides 10 which are also soldered to the portion 14.
Cela permet de renforcer l'unité mécanique que forme l'ensemble tubecollet-plaque. This reinforces the mechanical unit formed by the tubecollet-plate assembly.
Les figures 4 et 5 montrent un autre mode de réalisation. Figures 4 and 5 show another embodiment.
Dans ce mode de réalisation, l'échangeur est entièrement brasé, c'est-àdire que le couvercle n'est pas ici serti mais disposé sur le bord relevé de la plaque collectrice et brasé. In this embodiment, the exchanger is fully brazed, that is to say that the cover is not crimped here but arranged on the raised edge of the header plate and brazed.
En outre, dans l'exemple ici décrit, cet échangeur comporte deux rangée de tubes, et les collets sont ici dirigés vers l'intérieur de la boîte collectrice et pas vers le faisceau de tube. In addition, in the example described here, this exchanger has two rows of tubes, and the collars are here directed towards the inside of the header and not towards the tube bundle.
Comme on peut le voir sur la figure 4, une plaque collectrice 40 comporte une âme 42 percée de trous 44, bordée de collets 46. Il existe deux rangées R1 et R2 de trous 44 et de collets 46 destinés à recevoir des tubes tels que ceux décrits plus haut. Le positionnement des tubes dans les trous 44 est figuré par des pointillés. As can be seen in FIG. 4, a manifold plate 40 has a core 42 pierced with holes 44 flanked by collars 46. There are two rows R1 and R2 of holes 44 and flanges 46 intended to receive tubes such as those described above. The positioning of the tubes in the holes 44 is represented by dotted lines.
Les trous et les tubes présentent un grand axe X'X' et un petit axe Y'Y'. The holes and tubes have a major axis X'X 'and a small axis Y'Y'.
Dans ce mode de réalisation, les collets 46 comportent deux paires 50 et 52 de côtés opposés qui s'expriment également 35 selon les X'X' et Y'Y'. In this embodiment, the collars 46 have two pairs 50 and 52 of opposite sides which are also expressed as X'X 'and Y'Y'.
La paire 50 comporte deux côtés 50a et 50b qui sont réalisés par poinçonnage et relevage ou crevage de l'âme 42. Cependant, cette opération est réalisée vers l'intérieur du collecteur formé par la plaque collectrice et son couvercle, et non pas vers le faisceau de tubes comme décrit précédemment. The pair 50 has two sides 50a and 50b which are made by punching and lifting or tearing of the core 42. However, this operation is performed towards the inside of the manifold formed by the header plate and its cover, and not towards the bundle of tubes as described previously.
La paire 52 comporte deux côtés 52a et 52b. Le côté 52a est également formé par poinçonnage et relevage ou crevage en même temps que la paire 50. Le côté 52b est formé par une portion 54 d'un bord relevé 56 de la plaque 40. The pair 52 has two sides 52a and 52b. The side 52a is also formed by punching and lifting or puncturing at the same time as the pair 50. The side 52b is formed by a portion 54 of a raised edge 56 of the plate 40.
Sur la figure 5, on a représenté une variante de la figure 4 dans laquelle l'échangeur est dit "jointif". Au lieu de former les deux côtés 52a par poinçonnage et relevage ou crevage de l'âme, ceux-ci sont réduits autant que possible et les trous 44 des rangées Ri et R2 sont allongés jusqu'à communiquer au niveau d'une zone de jonction. In Figure 5, there is shown a variant of Figure 4 in which the exchanger is said "joined". Instead of forming the two sides 52a by punching and lifting or tearing of the core, they are reduced as much as possible and the holes 44 of the rows R 1 and R 2 are elongated to communicate at a junction zone .
Ainsi, des extrémités de tubes correspondants de rangées différentes sont en contact intime. Des portions de côté 62a sont formées par relevage de l'âme dans la zone de jonction des trous 44, et forment le côté 52a opposé au côté 52b pour chaque rangée de tubes. Le côté 52a est donc partagé par un tube de chaque rangée. Thus, ends of corresponding tubes of different rows are in intimate contact. Side portions 62a are formed by lifting the web in the junction area of the holes 44, and form the side 52a opposite the side 52b for each row of tubes. The side 52a is therefore shared by a tube of each row.
La figure 6 est une vue en coupe partielle du détail VI de la 25 figure 4 selon l'axe Z-Z. Cette vue permet de mieux apprécier les opérations de brasage à réaliser sur cet échangeur. Figure 6 is a partial sectional view of detail VI of Figure 4 along the Z-Z axis. This view makes it possible to better appreciate the brazing operations to be performed on this exchanger.
En effet, comme indiqué plus haut, les collets 44 sont ici dirigés vers "l'intérieur", et une flèche 60 indique la portion 54 au niveau de laquelle doit être réalisé le brasage. Indeed, as indicated above, the collars 44 are here directed to "inside", and an arrow 60 indicates the portion 54 at which the soldering is to be performed.
La description des exemples ci-dessus est donnée à titre illustratif et non limitatif. L'homme du métier saura notamment envisager toutes les combinaisons des modes de réalisation décrits ci-dessus ainsi que d'autres variantes. The description of the examples above is given for illustrative and not limiting. Those skilled in the art will especially consider all combinations of the embodiments described above as well as other variants.
Dans les exemples ici décrits, ce sont les petits côtés des collets qui sont généralement formés par le bord relevé de la plaque collectrice. On pourrait néanmoins imaginer des cas où les grands côtés seraient formés par le bord relevés, par exemple dans l'application de l'invention à des refroidisseurs de gaz, dans lesquels les tubes sont "torsadés". In the examples described here, it is the short sides of the collars which are generally formed by the raised edge of the collector plate. One could nevertheless imagine cases where the long sides would be formed by the raised edge, for example in the application of the invention to gas coolers, in which the tubes are "twisted".
L'invention trouve une application préférentielle aux échangeurs de chaleur pour véhicules automobiles, par exemple aux refroidisseurs d'air de suralimentation. Elle peut cependant être appliquée à d'autres échangeurs de chaleur, par exemple des radiateurs de refroidissement de moteur. The invention finds a preferential application to heat exchangers for motor vehicles, for example to charge air coolers. It can however be applied to other heat exchangers, for example engine cooling radiators.
L'étendue de l'invention n'est pas limitée par ses exemples et est à apprécier à l'aide des revendications qui suivent. The scope of the invention is not limited by its examples and is to be appreciated by means of the following claims.
