Abstract
Description
La présente invention concerne un échangeur de chaleur utilisé en particulier sur des véhicules automobiles pour le refroidissement d'un fluide de circulation ou le chauffage de l'air admis dans l'habitacle du véhicule.The present invention relates to a heat exchanger used in particular on motor vehicles for cooling a circulation fluid or heating the air admitted into the passenger compartment of the vehicle.
L'invention concerne plus particulièrement les échangeurs de chaleur à circulation de fluide en plusieurs passes tel que ceux, par exemple, plus communément appelés échangeurs en U ou à deux passes méthodiquesThe invention relates more particularly to heat exchangers with fluid circulation in several passes such as those, for example, more commonly called U-shaped exchangers or two methodical passes
Ce type d'échangeurs est constitué par un faisceau de tubes à ailettes doté d'au moins une boîte à fluide partagée intérieurement en deux compartiments par une cloison, l'un des compartiments, servant à l'arrivée et l'autre à la sortie du fluide de circulation. Ainsi, le fluide arrive dans le premier compartiment traverse une première partie du faisceau dans un premier sens puis retourne dans le second compartiment en ayant au préalable traversé la seconde partie du faisceau dans le sens opposé.This type of exchanger consists of a bundle of finned tubes provided with at least one fluid box divided internally into two compartments by a partition, one of the compartments, serving for the inlet and the other for the outlet. circulation fluid. Thus, the fluid arrives in the first compartment passes through a first part of the beam in a first direction and then returns to the second compartment having previously crossed the second part of the beam in the opposite direction.
Il a été constaté que la cloison délimitant la boîte à fluide en deux compartiments ne parvient pas a être reliée d'une manière parfaitement étanche à la plaque collectrice que comporte la boîte à fluide. De même l'expérience a montré que la différence de pression qui règne entre les deux compartiments et qui peut atteindre des valeurs relativement élevées est susceptible de provoquer la déformation de ladite cloison et, par conséquent, de produire des fuites entre les compartiments.It has been found that the partition delimiting the fluid box in two compartments fails to be connected in a perfectly sealed manner to the collector plate that the fluid box comprises. Likewise, experience has shown that the difference in pressure which prevails between the two compartments and which can reach relatively high values is capable of causing the deformation of said partition and, consequently, of producing leaks between the compartments.
Cet inconvénient s'aggrave dans le cas où la boîte à fluide est partagé intérieurement en deux compartiments par une cloison logitudinale de grande longueur.This drawback worsens in the case where the fluid box is divided internally into two compartments by a logitudinal wall of great length.
De même dans le cas où la boîte à fluide est partagé intérieurement en trois compartiments par deux cloisons transversales, tel que par exemple pour une circulation de fluide dit en quadricircuit, la différence de pression varie d une manière non négligeable du premier compartiment jusqu'au troisième compartiment.Similarly in the case where the fluid box is divided internally into three compartments by two transverse partitions, such as for example for a circulation of fluid called quadricircuit, the pressure difference varies in a non-negligible manner from the first compartment to third compartment.
Ces inconvénients se produisent quelques fois au moment du remplissage de l'échangeur lors de son utilisation sur véhicule qui le comporte, car ledit remplissage est fréquemment effectué en reliant l'un des compartiements de la boîte à fluide à une source de vide partiel afin de dégager le circuit de circulation auquel est branché l'échangeur en même temps que le remplissage est assuré.These disadvantages occur sometimes when the exchanger is filled when it is used on a vehicle which includes it, because said filling is frequently carried out by connecting one of the compartments of the fluid box to a source of partial vacuum in order to clear the circulation circuit to which is connected the exchanger at the same time as filling is ensured.
Les risques de déformation de la cloison prennent naissance également lorsque la pompe à eau du moteur débite fortement et que la pression est ainsi sensiblement augmentée dans l'un des compartiments par rapport à l'autre.The risks of deformation of the partition also arise when the engine's water pump delivers strongly and the pressure is thus appreciably increased in one of the compartments relative to the other.
La présente invention a pour but de remédier à ces inconvénients en permettant une étanchéité fiable et améliorée de ou des cloisons sur la plaque collectrice de la boîte à fluide.The object of the present invention is to remedy these drawbacks by allowing reliable and improved sealing of one or more partitions on the collector plate of the fluid box.
Suivant l'invention, l'échangeur de chaleur à au moins deux passes méthodiques comportant un faisceau de tubes à ailettes et au moins une boîte à fluide munie intérieurement d'au moins une cloison prenant appui à étanchéité sur la plaque collectrice que comporte ladite boîte à fluide en délimitant au moins deux compartiments, l'étanchéité étant assurée par une partie en élastomère serrée entre le bord libre de la cloison et la plaque collectrice , est caractérisé en ce que la plaque collectrice présente une rainure partiellement remplie par une nervure souple présentant elle-même une rainure pour recevoir le bord libre de la cloison et en ce que, des protubérances sont formées pour augmenter la rigidité de ladite cloison.According to the invention, the heat exchanger with at least two methodical passes comprising a bundle of finned tubes and at least one fluid box provided internally with at least one partition bearing sealing against the manifold plate that said box fluid by delimiting at least two compartments, the sealing being ensured by an elastomer part clamped between the free edge of the partition and the collecting plate, is characterized in that the collecting plate has a groove partially filled by a flexible rib having itself a groove for receiving the free edge of the partition and in that, protrusions are formed to increase the rigidity of said partition.
Grâce à cela la cloison est montée à étanchéité dans la rainure de la nervure et est bloquée dans sa position par les protubérances et cela quelque soit la pression régnant dans les compartiments.Thanks to this, the partition is mounted in a sealed manner in the groove of the rib and is locked in its position by the protrusions and this whatever the pressure prevailing in the compartments.
Suivant une autre caractéristique de l'invention, les protubérances sont formées par des nervures de la plaque collectrice.According to another characteristic of the invention, the protuberances are formed by ribs of the collector plate.
De ce fait, la plaque collectrice étant une pièce de plus grande rigidité que la cloison, ladite plaque participe d'une manière encore plus efficace au blocage de la cloison.Therefore, the collector plate being a piece of greater rigidity than the partition, said plate participates in an even more effective manner in blocking the partition.

D'une manière connue, l'échangeur comporte des tubes 1 munis d'ailettes 2. Dans le cas de la figure 1 les tubes 1 sont engagés dans des plaques collectrices 3,4 recouvertes par des boîtes à fluide 5,6. La boîte à fluide 5 est munie intérieurement d'une cloison longitudinale 7. De cette manière la boîte à fluide 5 est divisée en deux compartiments 8,9.In a known manner, the exchanger comprises tubes 1 provided with
Des embouts tels que 10 et 11 sont prévus pour permettre de faire communiquer les compartiements 8,9 avec un circuit de circulation de fluide, tel que par exemple l'eau circulant dans le circuit de refroidissement du moteur du véhicule automobile.Nozzles such as 10 and 11 are provided to allow the
En supposant que la circulation du liquide s'effectue à l'intérieur de l'échangeur, comme illustré par les flèches de la figure 1, cela correspond à ce qui est dénommé dans la technique une circulation à plusieurs passes méthodiques, ici, à deux passes méthodiques ou en U.Assuming that the circulation of the liquid takes place inside the exchanger, as illustrated by the arrows in FIG. 1, this corresponds to what is known in the art a circulation with several methodical passes, here, for two methodical or U-shaped passes.
L'échangeur de la figure 1 est illustré avec deux plaques collectrices et deux boîtes à fluide mais cet échangeur pourrait seulement comporter la plaque collectrice supérieure 3 et la boîte à fluide 5. Dans ce dernier cas, les tubes 1 seraient des tubes pliés en épingle ou en U.The exchanger of FIG. 1 is illustrated with two collector plates and two fluid boxes but this exchanger could only comprise the
De même, il pourrait être envisagé la configuration de figure 1, mais avec une disposition transversale de la cloison 7 dans la boîte à fluide 5, de façon à délimiter deux compartiments situés aux extrémités de ladite boîte.Similarly, it could be considered the configuration of Figure 1, but with a transverse arrangement of the
Les figures 2, 4 et 5 montrent que pour assurer l'étanchéité entre la plaque collectrice, en particulier la plaque collectrice 3 et la boîte à fluide correspondante, la plaque collectrice est recouverte, sur son côté dirigé vers la boîte à fluide, par une nappe 12 en matière souple du genre élastomère, qui est moulée pour délimiter des douilles 13 insérées dans des collets 14 de la plaque collectrice. De même la nappe 12 forme avantageusement un joint périphérique 15 pour assurer l'étanchéité avec la boîte à fluide.Figures 2, 4 and 5 show that to ensure the seal between the manifold plate, in particular the
Dans l'exemple décrit dans lequel l'échangeur comporte deux rangées de tubes 1 pouvant être formées chacune par les deux brins d'un tube en épingle, la plaque collectrice délimite entre les deux rangées de collets 14, 14a (figure 4) une rainure longitudinale 16 dans laquelle est insérée une nervure souple correspondante 17 formée par la nappe 12, cette nervure formant sur le côté de la nappe 12 tournée vers la boîte à fluide une rainure 17a destinées à recevoir le bord libre de la cloison longitudinale 7.In the example described in which the exchanger comprises two rows of tubes 1 which can each be formed by the two strands of a pin tube, the collector plate delimits between the two rows of
Lorsque les passages de tubes 14, 14a de la plaque collectrice sont très rapprochés, par exemple lorsque l'entraxe A des tubes est compris entre 10 et 20 mm et de préférence entre 17 et 17 mm pour des tubes 1 de section circulaire ayant un diamètre ⌀ compris entre 4 et 9mm, de préférence entre 6 et 7 mm, la profondeur P de la rainure 16 est nécessairement faible et comprise entre 1 et 4 mm, de préférence entre 2 et 3 mm suivant la nature des métaux utilisés pour la fabrication de la plaque collectrice, par exemple de l'acier, du laiton, du cuivre ou de l'aluminium.When the
Pour tenir compte de la profondeur nécessairement faible de la rainure 16 et plus encore de la rainure 17a, étant donné que l'épaisseur E de la nappe 12 est comprise entre 0,5 et 3 mm, de préférence entre 1 et 2 mm, on prévoit des protubérances transversales 18 qui, dans le mode de réalisation illustré, présentent la forme de nervure s'étendant perpendiculairement à la rainure 17 mais dont la concavité est opposé c'est-à-dire que la partie convexe des protubérances 18 est tournée vers l'intérieur de la boîte à fluide.To take account of the necessarily shallow depth of the
Les protubérances 18 sont également formées par emboutissage et présentent une profondeur analogue à celle de la rainure longitudinale 16, c'est-à-dire que leur profondeur est comprise entre 1 et 4 mm, de préférence entre 2 et 3 mm.The
La nappe 12 est conformée, ainsi que l'illustre le dessin, pour épouser les protubérances qui s'étendent jusqu'au voisinage immédiat de la rainure 16 et qui peuvent éventuellement n'être formée que jusqu'au voisinage de cette rainure 16 ce qui assure un calage des deux bords latéraux de la cloison 7 qui est ainsi centrée.The
L'espace e compris entre les axes géométriques de deux protubérances successives est compris entre 10 et 25 mm de préférence entre 15 et 20 mm lorsque les tubes présentent eux-mêmes un diamètre compris entre 4 et 9 mm, de préférence entre 6 et 7 mm, comme expliqué dans ce qui précède.The space e between the geometric axes of two successive protuberances is between 10 and 25 mm preferably between 15 and 20 mm when the tubes themselves have a diameter between 4 and 9 mm, preferably between 6 and 7 mm, as explained in the foregoing.
Suivant la variante de la figure 6 les protubérances sont constituées par des surépaisseurs 19 formées par la nappe 12. Comme l'illustre le dessin, les surépaisseurs 19 sont plus hautes entre deux rangs de tubes qu'entre deux tubes d'un même rang pour que la collerette supérieure 20 formée par la nappe 12 autour de chaque tube 1 ne soit pas affectée par ladite surépaisseur. Les surépaisseurs 19 de la nappe 12 peuvent être combinées aux protubérances 18 de la plaque collectrice.According to the variant of FIG. 6, the protuberances consist of
La figure 7 illustre une autre variante suivant laquelle des protubérances sont constituées par des nervures saillantes 21 directement formées à partir de la cloison 7 et placées de façon à venir prendre appui contre la partie 1a des tubes 1 qui fait saillie au-dessus des collerettes supérieures 20 de la nappe 12. Comme dans l'exemple précédent, les nervures 21 peuvent être mises en oeuvre conjointement aux protubérances 18 de la plaque collectrice.FIG. 7 illustrates another variant according to which protrusions are constituted by projecting
La figure 8 illustre encore une autre variante selon laquelle la rainure longitudinale 16 de la plaque collectrice présente une forme ondulée. Dans ce cas, la nervure 17 de la nappe 12 est également ondulée et les protubérances 18 déjà décrites peuvent ou non être mises en oeuvre, la cloison 7 de la boîte à fluide 5 est réalisée pour présenter les mêmes ondulations que la rainure 16 ce qui a pour effet d'augmenter sa rigidité. De plus, la forme ondulée de la rainure 16 pratiquée dans la plaque collectrice augmente sensiblement son moment de flexion axial par rapport à une rainure rectiligne.FIG. 8 illustrates yet another variant according to which the
Une variante supplémentaire est illustrée par les figure 9 à 11 selon laquelle pour augmenter le moment de flexion axial de la plaque collectrice, on forme des rainures de raidissement 22 plus profondes que la rainure longitudinale 16. Les rainures 22 ne nuisent pas à l'étanchéité puisqu'elles sont recouvertes par la nappe souple 12. Les rainures 22 sont formées entre les rangées de passage de tube 14, 14a et ménagent des plages libres 23, 23a à intervalles réguliers dans lesquelles sont formées des protubérances 24, 24a se faisant vis à vis de la même manière que les protubérances 18 des figureS 3 et 4.An additional variant is illustrated in FIGS. 9 to 11 according to which, to increase the axial bending moment of the manifold plate,
L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiments shown and described in detail, since various modifications can be made thereto without departing from its scope.
