Echangeur de chaleur à plaques comportant un élément d'obturation des fuites du gaz à refroidir L'invention se rapporte aux échangeurs de chaleur, et plus particulièrement aux échangeurs de chaleur à plaques pour les véhicules automobiles. The invention relates to heat exchangers, and more particularly to plate heat exchangers for motor vehicles.
Elle concerne plus particulièrement un échangeur de chaleur pour l'échange de chaleur entre un fluide à refroidir et un fluide de refroidissement, comprenant un faisceau d'échange de chaleur constitué d'un empilement de plaques déterminant entre elles des canaux de circulation alternés pour le fluide 15 à refroidir et pour le fluide de refroidissement, des intercalaires étant disposés dans les canaux de circulation du fluide à refroidir, une enveloppe logeant le faisceau d'échange de chaleur, un collecteur d'entrée pour distribuer le fluide à refroidir dans les canaux de circulation du 20 fluide à refroidir et un collecteur de sortie pour évacuer le fluide à refroidir des canaux de circulation du fluide à refroidir. It relates more particularly to a heat exchanger for the heat exchange between a fluid to be cooled and a cooling fluid, comprising a heat exchange bundle consisting of a stack of plates determining between them alternating circulation channels for the fluid 15 to be cooled and for the coolant, dividers being arranged in the circulation channels of the fluid to be cooled, an envelope housing the heat exchange bundle, an inlet manifold for distributing the fluid to be cooled in the channels circulation of the fluid to be cooled and an outlet manifold for discharging the fluid to be cooled from the circulation channels of the fluid to be cooled.
Dans les échangeurs de ce type, les plaques ont le plus 25 souvent la forme générale d'un rectangle allongé ayant deux petits côtés, chaque plaque comportant deux bossages situés le long d'un même petit côté de la plaque, ces bossages étant en appui sur les bossages d'une plaque adjacente pour former respectivement un collecteur d'entrée et un collecteur de 30 sortie pour le fluide de refroidissement. In exchangers of this type, the plates most often have the general shape of an elongated rectangle having two short sides, each plate having two bosses located along the same short side of the plate, these bosses being in abutment on the bosses of an adjacent plate to respectively form an inlet manifold and an outlet manifold for the coolant.
Les intercalaires, qui sont généralement de forme ondulée, forment des surfaces d'échange secondaires et/ou des éléments perturbateurs. Ils sont disposés dans les canaux de circula35 tion du fluide à refroidir, ont une longueur correspondant à la longueur totale des plaques moins l'espace occupé par les bossages qui constituent le collecteur d'entrée et le collecteur de sortie du fluide de refroidissement. En consequence, il existe des fuites de gaz à refroidir entre 40 l'extrémité des intercalaires et l'enveloppe du faisceau d'échange de chaleur. Ces fuites mettent en communication directe le collecteur d'entrée et le collecteur de sortie du fluide à refroidir, sans traverser la surface d'échange de chaleur. Le fluide qui passe par ces fuites n'est pas 5 refroidi, ce qui se traduit par une baisse du rendement d'échange thermique de l'échangeur. The spacers, which are generally of corrugated shape, form secondary exchange surfaces and / or disturbing elements. They are arranged in the circulation channels of the fluid to be cooled, have a length corresponding to the total length of the plates minus the space occupied by the bosses which constitute the inlet manifold and the outlet manifold of the cooling fluid. Consequently, there are gas leaks to be cooled between the end of the inserts and the envelope of the heat exchange bundle. These leaks put the inlet manifold and the outlet manifold of the fluid to be cooled in direct communication, without passing through the heat exchange surface. The fluid which passes through these leaks is not cooled, which results in a reduction in the heat exchange efficiency of the exchanger.
L'invention a précisément pour but de réaliser un échangeur de chaleur qui remédie à ces inconvénients. L'échangeur de 10 chaleur de l'invention comporte, à cet effet, des moyens d'obturation situés entre l'enveloppe et les intercalaires pour interdire le passage du fluide à refroidir du collecteur d'entrée au collecteur de sortie. The object of the invention is precisely to produce a heat exchanger which overcomes these drawbacks. The heat exchanger of the invention comprises, for this purpose, sealing means situated between the casing and the spacers to prevent the passage of the fluid to be cooled from the inlet manifold to the outlet manifold.
Dans un mode de réalisation particulier, ces moyens d'obturation sont constitués par au moins une cloison disposée entre le collecteur d'entrée et le collecteur de sortie du fluide de refroidissement. Cette cloison peut présenter, notamment, une section en forme de U. Dans une autre réalisation, l'élément d'obturation est constitué par un élément d'obturation ayant une section en forme de U et monté sur le faisceau d'échange de chaleur le long du petit côté des plaques comportant le collecteur 25 d'entrée et le collecteur de sortie du fluide de refroidissement. In a particular embodiment, these sealing means consist of at least one partition disposed between the inlet manifold and the outlet manifold of the cooling fluid. This partition may have, in particular, a U-shaped section. In another embodiment, the closure element is constituted by a closure element having a U-shaped section and mounted on the heat exchange bundle along the short side of the plates comprising the inlet manifold and the coolant outlet manifold.
Dans encore un autre mode de réalisation, les moyens d'obturation sont constitués par un rebord formé à la 30 périphérie des bossages des plaques, ce rebord s'étendant au moins des intercalaires à l'enveloppe du faisceau d'échange de chaleur. In yet another embodiment, the sealing means are constituted by a flange formed at the periphery of the bosses of the plates, this flange extending at least from the spacers to the envelope of the heat exchange bundle.
Enfin, dans un autre mode de réalisation encore, les moyens 35 d'obturation sont constitués par un embouti formé entre les deux bossages des plaques de l'échangeur de chaleur. Finally, in yet another embodiment, the sealing means 35 are constituted by a stamp formed between the two bosses of the plates of the heat exchanger.
Cet embouti peut comporter un bord tombé qui vient en appui contre l'enveloppe afin de faciliter la réalisation d'une liaison étanche pendant l'opération de brasage de l'échangeur. This stamping may include a fallen edge which bears against the envelope in order to facilitate the production of a sealed connection during the brazing operation of the exchanger.
Ces moyens d'obturation permettent ainsi de supprimer la 5 fuite de gaz à refroidir qui existe dans les échangeurs de l'art antérieur. En conséquence, la totalité du fluide à refroidir est contrainte de circuler à travers la surface d'échange de chaleur de sorte que le rendement thermique de l'échangeur de chaleur n'est pas diminué. 10 D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description qui suit d'exemples de réalisation donnés à titre illustratif en référence aux figures annexées. Sur ces figures: 15 la figure 1 est une vue en perspective d'un échangeur de chaleur conforme à l'art antérieur; - la figure 2 est une vue en coupe partielle à échelle 20 agrandie de l'échangeur de chaleur de l'art antérieur de la figure 1; la figure 3 est une vue en perspective, partiellement éclatée, d'un échangeur de chaleur conforme à un premier mode 25 de réalisation de l'invention; - la figure 4 est une vue en perspective d'un deuxième mode de réalisation d'un échangeur de chaleur conforme à la présente invention; - la figure 5 est une vue en perspective, partiellement éclatée, d'un troisième mode de réalisation d'un échangeur de chaleur conforme à l'invention; et - la figure 6 est une vue en perspective, partiellement éclatée d'un faisceau d'échange de chaleur illustrant un troisième mode de réalisation de l'invention. These sealing means thus make it possible to eliminate the leak of gas to be cooled which exists in the exchangers of the prior art. Consequently, all of the fluid to be cooled is forced to flow through the heat exchange surface so that the thermal efficiency of the heat exchanger is not reduced. 10 Other characteristics and advantages of the invention will become apparent on reading the following description of embodiments given by way of illustration with reference to the appended figures. In these figures: Figure 1 is a perspective view of a heat exchanger according to the prior art; - Figure 2 is an enlarged partial sectional view of the prior art heat exchanger of Figure 1; Figure 3 is a partially exploded perspective view of a heat exchanger according to a first embodiment of the invention; - Figure 4 is a perspective view of a second embodiment of a heat exchanger according to the present invention; - Figure 5 is a perspective view, partially exploded, of a third embodiment of a heat exchanger according to the invention; and - Figure 6 is a partially exploded perspective view of a heat exchange bundle illustrating a third embodiment of the invention.
On a représenté sur les figures 1 et 2 respectivement une vue en perspective et une vue en coupe partielle d'un échangeur de chaleur à plaques, dans l'exemple un refroidisseur d'air de suralimentation d'un véhicule automobile, conforme à l'art 5 antérieur. Il est constitué d'un faisceau d'échange de chaleur, désigné par la référence générale 2, contenu à l'intérieur d'une enveloppe désignée par la référence générale 4. Le faisceau est constitué par la superposition d'une pluralité de plaques embouties 8 de forme générale 10 rectangulaire. Chaque plaque 8 comporte une paroi de fond 10, sensiblement plane, entourée par un rebord périphérique 12 terminé par un méplat 14. Le fond 10 et le rebord 12 déterminent une cuvette peu profonde destinée à la circulation du fluide de refroidissement. There is shown in Figures 1 and 2 respectively a perspective view and a partial sectional view of a plate heat exchanger, in the example a charge air cooler of a motor vehicle, in accordance with prior art 5. It consists of a heat exchange bundle, designated by the general reference 2, contained inside an envelope designated by the general reference 4. The bundle is formed by the superposition of a plurality of stamped plates 8 generally 10 rectangular. Each plate 8 has a substantially flat bottom wall 10, surrounded by a peripheral rim 12 terminated by a flat 14. The bottom 10 and the rim 12 determine a shallow bowl intended for the circulation of the cooling fluid.
Comme on peut le voir plus particulièrement sur la figure 2, les plaques 8 sont groupées par paires et assemblées par leurs méplats 14. De la sorte, les cuvettes de la plaque supérieure 8a et de la plaque inférieure 8b d'une paire de 20 plaques s'ajoutent pour constituer un canal 16 de circulation du fluide de refroidissement. Par ailleurs, deux bossages 18 sont formés le long d'un petit côté du rectangle formé par chacune des plaques. Le fond de chaque bossage comporte un passage de circulation 20 pour le fluide de refroidissement. 25 Les bossages d'une paire de plaques 8a, 8b sont en appui sur les bossages des paires de plaques adjacentes. On réalise ainsi un collecteur d'entrée 22 et un collecteur de sortie (non référencé) pour le fluide de refroidissement. Le fluide de refroidissement pénètre dans le faisceau comme schématisé 30 par la flèche 24, puis circule, de gauche à droite selon la figure 2, dans les canaux de circulation 16 comme schématisé par les flèches 26. La sortie du fluide de l'échangeur s'effectue en sens inverse. As can be seen more particularly in FIG. 2, the plates 8 are grouped in pairs and assembled by their flats 14. In this way, the bowls of the upper plate 8a and of the lower plate 8b of a pair of 20 plates are added to constitute a channel 16 for circulation of the cooling fluid. Furthermore, two bosses 18 are formed along a short side of the rectangle formed by each of the plates. The bottom of each boss has a circulation passage 20 for the cooling fluid. The bosses of a pair of plates 8a, 8b are supported on the bosses of the pairs of adjacent plates. This produces an inlet manifold 22 and an outlet manifold (not referenced) for the cooling fluid. The cooling fluid enters the bundle as shown diagrammatically by the arrow 24, then circulates, from left to right according to FIG. 2, in the circulation channels 16 as shown diagrammatically by the arrows 26. The outlet of the fluid from the exchanger s 'performs in reverse.
Les bossages de deux paires de plaques déterminent entre eux des canaux de circulation 30 pour le fluide à refroidir, généralement un gaz. Comme on peut le voir sur la figure 1, les canaux de circulation 30 du gaz à refroidir, l'air de suralimentation dans l'exemple, sont perpendiculaires aux canaux de circulation 16 du liquide de refroidissement, généralement l'eau du circuit de refroidissement du moteur du véhicule. La circulation de ces deux fluides s'effectue ainsi à courants croisés. Afin d'améliorer l'échange de chaleur, 5 des intercalaires 32 sont disposés dans chacun des canaux de circulation 30. Ils se présentent sous la forme d'intercalaires ondulés comportant une paroi inclinée 34 s'étendant obliquement par rapport aux parois de fond 10 des plaques 8 de l'échangeur. Ces intercalaires forment des surface 10 d'échange secondaire et/ou des éléments perturbateurs. The bosses of two pairs of plates determine between them circulation channels 30 for the fluid to be cooled, generally a gas. As can be seen in FIG. 1, the circulation channels 30 of the gas to be cooled, the charge air in the example, are perpendicular to the circulation channels 16 of the coolant, generally the water in the cooling circuit of the vehicle engine. The circulation of these two fluids is thus carried out at crossed currents. In order to improve the heat exchange, 5 of the spacers 32 are arranged in each of the circulation channels 30. They are in the form of corrugated spacers having an inclined wall 34 extending obliquely to the bottom walls 10 plates 8 of the exchanger. These spacers form secondary exchange surfaces 10 and / or disturbing elements.
L'enveloppe 4 est constituée d'un demi-carter supérieur 5 et d'un demicarter inférieur 6 emboîtés l'un dans l'autre de manière à loger le faisceau d'échange de chaleur. Deux 15 ouvertures 7 (une seule représentée sur la figure 1) sont prévues dans le demi-carter supérieur 5 de l'enveloppe pour l'entrée et la sortie du fluide de refroidissement. Le demicarter supérieur 5 et le demi-carter inférieur 6 ont une forme générale rectangulaire. Leur largeur est légèrement 20 supérieure à la largeur des plaques 8 de manière à ménager, le long de chacun des grands côtés des plaques, respectivement un collecteur d'entrée et un collecteur de sortie pour le fluide à refroidir. The envelope 4 consists of an upper half-casing 5 and a lower half-casing 6 fitted one inside the other so as to house the heat exchange bundle. Two openings 7 (only one shown in FIG. 1) are provided in the upper half-casing 5 of the casing for the inlet and the outlet of the coolant. The upper half-casing 5 and the lower half-casing 6 have a generally rectangular shape. Their width is slightly greater than the width of the plates 8 so as to provide, along each of the long sides of the plates, respectively an inlet manifold and an outlet manifold for the fluid to be cooled.
Une boîte collectrice d'entrée et une boîte collectrice de sortie (non représentées) sont adaptées à la périphérie de l'enveloppe 4 pour l'amenée et l'évacuation de l'air de suralimentation. Comme on peut le constater, les intercalaires ondulés 32 s'étendent sur toute la longueur des plaques, 30 à l'exception de la partie qui comporte les bossages 18. Il existe donc entre la paroi verticale de chacun des demicarters 5 et 6 et la paroi inclinée terminale 34 de chacun des intercalaires ondulés, des passages 38 qui mettent directement en communication le collecteur d'entrée et le 35 collecteur de sortie du gaz à refroidir, sans que ce gaz traverse la surface d'échange de chaleur matérialisée par les intercalaires ondulés 32. Les passages 38 constituent donc des fuites préjudiciables au bon fonctionnement de l'échangeur, comme montré par les flèches F de la figure 1. An inlet manifold and an outlet manifold (not shown) are adapted to the periphery of the casing 4 for supplying and evacuating the charge air. As can be seen, the corrugated spacers 32 extend over the entire length of the plates, 30 with the exception of the part which includes the bosses 18. There therefore exists between the vertical wall of each of the demounters 5 and 6 and the end inclined wall 34 of each of the corrugated inserts, passages 38 which directly connect the inlet manifold and the outlet manifold of the gas to be cooled, without this gas passing through the heat exchange surface materialized by the inserts corrugated 32. The passages 38 therefore constitute leaks detrimental to the proper functioning of the exchanger, as shown by the arrows F in FIG. 1.
On a représenté sur la figure 3 une vue en perspective partiellement éclatée d'un refroidisseur d'air de suralimentation conforme à l'invention. Dans ce mode de réalisation, une découpe 40 est prévue sur chacune des plaques 8 entre les 5 bossages 18 constituant le collecteur d'entrée et les bossages constituant le collecteur de sortie du fluide de refroidissement. Une cloison 42 est insérée dans la découpe 40. Afin d'obturer entièrement les passages de fuites 38, la cloison 42 s'étend des côtés verticaux 9 de chacun des demi10 carters 5 et 6 jusqu'à la paroi terminale inclinée 34 de chacun des intercalaires ondulés 32. Cette cloison peut prendre des formes différentes sans sortir du cadre de l'invention. Dans l'exemple représenté sur la figure 3, la cloison 42 comporte une section transversale en forme de U. 15 Cette section est avantageuse parce qu'elle permet un contact important entre la partie plane du U et la paroi terminale inclinée 34 des intercalaires ondulés, ce qui permet d'assurer une bonne liaison au moment du brasage. De la même manière, la cloison 42 comporte des rebords repliés perpendi20 culairement aux branches du U de manière à assurer une bonne surface de liaison entre les extrémités des branches du U et les parois verticales 9 des carters 5 et 6. FIG. 3 shows a partially exploded perspective view of a charge air cooler according to the invention. In this embodiment, a cutout 40 is provided on each of the plates 8 between the 5 bosses 18 constituting the inlet manifold and the bosses constituting the outlet manifold of the cooling fluid. A partition 42 is inserted in the cutout 40. In order to completely seal the leakage passages 38, the partition 42 extends from the vertical sides 9 of each of the half-housings 5 and 6 to the inclined end wall 34 of each of the corrugated spacers 32. This partition can take different forms without departing from the scope of the invention. In the example shown in FIG. 3, the partition 42 has a U-shaped cross section. This section is advantageous because it allows significant contact between the flat part of the U and the inclined end wall 34 of the corrugated inserts , which ensures a good bond during soldering. Similarly, the partition 42 has flanges folded perpendicularly to the branches of the U so as to ensure a good connection surface between the ends of the branches of the U and the vertical walls 9 of the housings 5 and 6.
On a représenté sur la figure 4 une vue en perspective d'un 25 deuxième mode de réalisation de moyens d'obturation conformes à l'invention. Ces moyens sont constitués par un élément d'obturation, désigné par la référence générale 44, qui présente la forme d'un U. Il comporte une paroi de fond 45 et deux joues 46 sensiblement perpendiculaires à la paroi 45. 30 L'élément d'obturation 44 vient s'appliquer sur l'extérieur du faisceau. La paroi de fond 45 est plaquée contre le petit côté des plaques 8 comportant les bossages 18. Les joues latérales 46 possèdent une longueur telle qu'elles s'étendent sensiblement jusqu'aux parois terminales inclinées 34 des 35 intercalaires ondulés 32. Les joues latérales 46 sont en outre de préférence raccordées au fond 44 par un rayon de courbure égal à celui des plaques 18. Ainsi, l'élément d'obturation 44 empêche l'air de suralimentation à refroidir de traverser l'échangeur en dehors de la zone d'échange de chaleur comprise entre les intercalaires ondulés. Les fuites sont ainsi éliminées. FIG. 4 shows a perspective view of a second embodiment of sealing means according to the invention. These means consist of a closure element, designated by the general reference 44, which has the shape of a U. It comprises a bottom wall 45 and two cheeks 46 substantially perpendicular to the wall 45. 30 The element d shutter 44 is applied to the outside of the bundle. The bottom wall 45 is pressed against the short side of the plates 8 comprising the bosses 18. The side cheeks 46 have a length such that they extend substantially to the inclined end walls 34 of the 35 corrugated inserts 32. The side cheeks 46 are also preferably connected to the bottom 44 by a radius of curvature equal to that of the plates 18. Thus, the shutter element 44 prevents the charge air to cool to pass through the exchanger outside the zone d heat exchange between the corrugated spacers. Leaks are thus eliminated.
On a représenté sur la figure 5 une vue en perspective d'un 5 troisième mode de réalisation de l'invention. Chacune des plaques 8 comporte un bord tombé 48 qui entoure partiellement les bossages 18. Les bords tombés sont réalisés de préférence par emboutissage en même temps que les autres reliefs de la plaque 8. Les bords tombés 48 sont de préférence limités à la 10 partie arrière des bossages pour ne pas engager un surplus de matière. Toutefois, il est nécessaire, conformément à l'invention, qu'ils s'étendent au minimum, dans le sens de la longueur des plaques, de la paroi intérieure de l'enveloppe 4 jusqu'aux parois terminales inclinées 34 des intercalaires 15 ondulés. Les bords tombés 48 constituent ainsi un moyen simple et peu coûteux d'obturer les passages de fuite 38 (figure 2). FIG. 5 shows a perspective view of a third embodiment of the invention. Each of the plates 8 has a dropped edge 48 which partially surrounds the bosses 18. The fallen edges are preferably produced by stamping at the same time as the other reliefs of the plate 8. The dropped edges 48 are preferably limited to the rear part bosses so as not to engage excess material. However, it is necessary, in accordance with the invention, that they extend at least, in the direction of the length of the plates, from the inner wall of the casing 4 to the inclined end walls 34 of the corrugated inserts 15 . The fallen edges 48 thus constitute a simple and inexpensive means of closing the leakage passages 38 (FIG. 2).
On a représenté sur la figure 6 une vue en perspective d'un 20 quatrième mode de réalisation de l'invention. Chacune des plaques 8 comporte un embouti 50 formé entre deux bossages 18. Ces emboutis sont situés du même côté, par rapport à la paroi de fond 10 de la plaque, que les bossages 18. Les faces planes des emboutis 50 sont liées de manière étanche les unes 25 aux autres par brasage. FIG. 6 shows a perspective view of a fourth embodiment of the invention. Each of the plates 8 comprises a stamped 50 formed between two bosses 18. These stamps are located on the same side, relative to the bottom wall 10 of the plate, as the bosses 18. The flat faces of the stamped 50 are tightly linked to each other by soldering.
Dans le sens de la longueur des plaques, chaque bossage 50 s'étend sensiblement depuis l'extrémité terminale des intercalaires ondulés 32 jusqu'à la paroi interne 9 des demi30 carters 5 et 6 de manière à obturer aussi complètement que possible les passages de fuites 38. Les emboutis 50 constituent ainsi un moyen simple et peu coûteux d'obturer ces passages de fuite. En effet, ils peuvent être réalisés de manière simple, par emboutissage, en même temps que les 35 autres reliefs de la plaque. D'autre part, ils ne nécessitent pas l'adjonction d'une pièce supplémentaire ni un apport de matière, étant donné qu'ils sont réalisés dans la surface de la plaque elle-même. In the lengthwise direction of the plates, each boss 50 extends substantially from the terminal end of the corrugated spacers 32 to the internal wall 9 of the half-housings 5 and 6 so as to close the leakage passages as completely as possible 38. The stampings 50 thus constitute a simple and inexpensive means of closing these leakage passages. In fact, they can be produced in a simple manner, by stamping, at the same time as the other reliefs of the plate. On the other hand, they do not require the addition of an additional part or an addition of material, since they are made in the surface of the plate itself.
L'invention ne se limite pas à des refroidisseurs d'air de suralimentation et s'applique aussi à d'autres types d'échangeurs de chaleur. The invention is not limited to charge air coolers and also applies to other types of heat exchangers.
