Description

L'invention concerne une boite à eau d'un échangeur de chaleur pour véhicule automobile, cette boite à eau contenant un radiateur d'huile, pour permettre, essentiellement, de refroidir par le liquide circulant dans l'échangeur l'huile qui circule dans le radiateur.The invention relates to a water box of a heat exchanger for a motor vehicle, this water box containing an oil radiator, to allow, essentially, to cool by the liquid circulating in the exchanger the oil which circulates in the radiator.

Dans les dispositifs connus de ce type, le radiateur d'huile est placé dans la boite à eau avant montage de celle-ci sur l'extrémité d'un faisceau de tubes ou d'un corps d'échangeur de chaleur, le radiateur d'huile étant introduit dans la boite à eau par la face ouverte de celle-ci qui viendra coiffer l'extrémité du corps ou du faisceau de tubes de l'échangeur. Le radiateur d'huile comprend deux tubulures de raccordement au circuit d'huile de lubrification du moteur et/ou de la boîte de vitesse, ces deux tubulures étant montées à étanchéité et fixées dans deux orifices de la paroi latérale de la boîte à eau, qui ont un diamètre correspondant sensiblement au diamètre externe des tubulures,pour des raisons d'étanchéité.In known devices of this type, the oil radiator is placed in the water box before mounting it on the end of a bundle of tubes or a heat exchanger body, the radiator d oil being introduced into the water box through the open face thereof which will cap the end of the body or of the bundle of tubes of the exchanger. The oil radiator comprises two pipes connecting to the lubricating oil circuit of the engine and / or the gearbox, these two pipes being sealed and fixed in two holes in the side wall of the water box, which have a diameter corresponding substantially to the external diameter of the pipes, for sealing reasons.

Pour que ce montage du radiateur dans la boîte à eau soit possible, il faut que la boîte à eau ait une largeur au moins sensiblement égale à l'encombrement total du radiateur d'huile dans la même dimension, c'est-à-dire en général à la largeur du radiateur augmentée de la longueur des tubulures. La boîte à eau doit donc avoir une largeur relativement importante, qui est largement supérieure à l'épaisseur, ou dimension correspondante, des faisceaux de tubes,des échangeurs actuels et qui est donc disproportionnée par rapport à cette dimension du faisceau.For this mounting of the radiator in the water box to be possible, the water box must have a width at least substantially equal to the total size of the oil radiator in the same dimension, that is to say in general to the width of the radiator increased by the length of the pipes. The water box must therefore have a relatively large width, which is much greater than the thickness, or corresponding dimension, of the tube bundles, current exchangers and which is therefore disproportionate to this dimension of the bundle.

On a déjà proposé, comme décrit par exemple dans le brevet français 2 549 593, d'incliner le radiateur pour l'introduire dans la boîte à eau par la face ouverte de celle-ci, de telle sorte que les tubulures du radiateur puissent être introduites en biais dans les orifices de la paroi latérale de la boite à eau. Il faut cependant pour cela que la boîte à eau ait une largeur plus importante que celle d'une boîte à eau classique, ce qui conduit à utiliser des boîtes à eau spéciales, ainsi que des collecteurs et des joints d'étanchéité spéciaux, à la place des boîtes à eau, des collecteurs et des joints d'étanchéité usuels lorsque l'on veut disposer un radiateur d'huile à l'intérieur d'une boîte à eau.It has already been proposed, as described for example in French patent 2,549,593, to tilt the radiator to introduce it into the water box through the open face of the latter, so that the radiator pipes can be introduced at an angle into the holes in the side wall of the water box. However, this requires that the water box be wider than that of a conventional water box, which leads to the use of special water boxes, as well as special collectors and seals, at the places the usual water boxes, collectors and seals when you want to have an oil radiator inside a water box.

L'invention a notamment pour but d'éviter ces inconvénients.The object of the invention is in particular to avoid these drawbacks.

Elle a pour objet une boîte à eau pour un échangeur de chaleur, qui a les mêmes dimensions et le même encombrement général que les boîtes à eau usuelles et qui peut cependant contenir le même radiateur d'huile que les boîtes à eau larges de la technique antérieure.It relates to a water box for a heat exchanger, which has the same dimensions and the same overall dimensions as the usual water boxes and which can however contain the same oil radiator as the wide water boxes of the technique anterior.

L'invention propose donc, à cet effet, une boîte à eau d'un échangeur de chaleur pour véhicules automobiles, comprenant un radiateur d'huile à deux tubulures d'entrée et de sortie d'huile qui traversent à étanchéité deux ouvertures d'une paroi latérale de la boite à eau et par lesquelles le radiateur d'huile est maintenu et fixé dans la boîte à eau, caractérisée en ce que ces ouvertures ont une dimension largement supérieure au diamètre extérieur des tubulures et sont fermées par deux plaques rapportées dont chacune comprend un orifice de passage d'une tubulure et est fixée sur le bord de l'ouverture correspondante.The invention therefore provides, for this purpose, a water box of a heat exchanger for motor vehicles, comprising an oil radiator with two oil inlet and outlet pipes which seal two openings of a side wall of the water box and by which the oil radiator is held and fixed in the water box, characterized in that these openings have a dimension much greater than the outside diameter of the pipes and are closed by two attached plates each of which comprises an orifice for the passage of a tube and is fixed to the edge of the corresponding opening.

Cette caractéristique de structure de la boîte à eau permet d'utiliser les mêmes collecteurs et les mêmes joints d'étanchéité que dans le cas où la boîte à eau est du type usuel et ne contient pas de radiateur d'huile, et permet également d'utiliser les radiateurs d'huile qui étaient auparavant montés dans les boîtes à eau larges.This structural characteristic of the water box makes it possible to use the same collectors and the same seals as in the case where the water box is of the usual type and does not contain an oil radiator, and also allows '' use the oil radiators which were previously fitted in large water boxes.

Chaque ouverture de la paroi latérale de la boîte à eau a une dimension ou un diamètre permettant le débattement d'une tubulure du radiateur d'huile lorsque ce dernier est introduit dans la boîte à eau par la face ouverte de celle-ci.Each opening of the side wall of the water box has a dimension or a diameter allowing the deflection of a tube of the oil radiator when the latter is introduced into the water box through the open face of the latter.

De plus, chaque tubulure du radiateur d'huile comprend un rebord annulaire qui est appliqué sur la face interne de la plaque précitée, et une partie à filetage extérieur, qui s'étend de l'autre côté de la plaque et reçoit un écrou serrant cette plaque sur le rebord annulaire.In addition, each tube of the oil radiator comprises an annular flange which is applied to the internal face of the aforementioned plate, and a part with an external thread, which extends on the other side of the plate and receives a tightening nut. this plate on the annular rim.

Dans la description qui suit, faite à titre d'exemple, on se réfère aux dessins annexés, dans lesquels :

  • - la figure 1 est une vue schématique en coupe transversale de la partie supérieure d'un échangeur de chaleur, représentant une boîte à eau de la technique antérieure comprenant un radiateur d'huile;
  • - la figure 2 est une vue schématique correspondant à la figure 1, mais représente une boîte à eau selon l'invention dans laquelle est contenu le même radiateur d'huile que celui de la figure 1;
  • -la figure 3 représente le radiateur d'huile;
  • - la figure 4 est une vue en élévation de la boîte à eau selon l'invention.
In the description which follows, given by way of example, reference is made to the appended drawings, in which:
  • - Figure 1 is a schematic cross-sectional view of the upper part of a heat exchanger, showing a water box of the prior art comprising an oil radiator;
  • - Figure 2 is a schematic view corresponding to Figure 1, but shows a water box according to the invention in which is contained the same oil radiator as that of Figure 1;
  • FIG. 3 represents the oil radiator;
  • - Figure 4 is an elevational view of the water box according to the invention.

On se réfère d'abord à la figure 1, représentant une boîte à eau de la technique antérieure, contenant un radiateur d'huile.Reference is first made to FIG. 1, representing a water box of the prior art, containing an oil radiator.

La boîte à eau connue, désignée par la référence 10, est montée de façon classique à une extrémité d'un faisceau de tubes 12, au moyen d'un collecteur ou plaque à tubes 14, et contient un radiateur d'huile 16 de type tubulaire classique.The known water box, designated by the reference 10, is conventionally mounted at one end of a bundle of tubes 12, by means of a manifold or tube plate 14, and contains an oil radiator 16 of the type classic tubular.

Ce radiateur 16, représenté également en figure 3, comprend deux parois cylindriques coaxiales 18 et 20 à section circulaire-s,reliées à étanchéité à leurs extrémités, et deux tubulures 22 disposées au voisinage de ces extrémités axiales et débouchant dans l'espace annulaire compris entre les parois cylindriques 18 et 20. Chaque tubulure 22 est orientée perpendiculairement à l'axe 24 du radiateur 16 et comprend une bride ou un rebord annulaire 26 au voisinage immédiat de la paroi cylindrique extérieure 18 du radiateur, et une partie cylindrique d'extrémité à filetage extérieur 28 destinée à recevoir un écrou 30.This radiator 16, also shown in FIG. 3, comprises two coaxial cylindrical walls 18 and 20 of circular cross section - s, connected with sealing at their ends, and two pipes 22 arranged in the vicinity of these axial ends and opening into the annular space included between the cylindrical walls 18 and 20. Each tube 22 is oriented perpendicular to the axis 24 of the radiator 16 and comprises a flange or an annular flange 26 in the immediate vicinity of the external cylindrical wall 18 of the radiator, and a cylindrical end part with external thread 28 intended to receive a nut 30.

La boîte à eau 10 comprend une paroi latérale 32 percée de deux orifices dans lesquels sont engagées les parties cylindriques d'extrémités 28 des tubulures 22 du radiateur. Les brides ou rebords annulaires 26 des tubulures 22 sont appliquées sur la face interne de la paroi latérale 32 de la boîte à eau avec interposition d'un joint d'étanchéité, et les écrous 30 vissés sur les extrémités 28 des tubulures sont serrés sur la face externe de la paroi latérale 32, de sorte que le radiateur d'huile 16 est ainsi maintenu et fixé sur la paroi latérale 32 de la boîte à eau 10.The water box 10 comprises a side wall 32 pierced by two orifices in which the cylindrical end portions 28 of the pipes 22 of the radiator are engaged. The annular flanges or flanges 26 of the pipes 22 are applied to the internal face of the side wall 32 of the water box with the interposition of a seal, and the nuts 30 screwed onto the ends 28 of the pipes are tightened on the external face of the side wall 32, so that the oil radiator 16 is thus maintained and fixed on the side wall 32 of the water box 10.

Au montage, avant que la boîte à eau 10 soit fixée sur le collecteur 14, le radiateur d'huile 16 est introduit dans la boîte à eau par la face ouverte de celle-ci, qui vient coiffer l'extrémité du faisceau de tubes 12 et comprend un rebord périphérique (non visible en figure 1) par lequel elle peut être fixée au collecteur 14.During assembly, before the water box 10 is fixed to the manifold 14, the oil radiator 16 is introduced into the water box through the open face thereof, which covers the end of the bundle of tubes 12 and includes a peripheral rim (not visible in FIG. 1) by which it can be fixed to the manifold 14.

Pour que ce montage soit possible, il faut que la largeur interne L de la boîte à eau 10 soit sensiblement égale à l'encombrement 1 du radiateur 16 en largeur, constitué par le diamètre extérieur de sa paroi cylindrique extérieure 18 et la longueur des tubulures 22. La largeur L de la boîte à eau 10 est ainsi largement supérieure à la dimension correspondante d du faisceau de tubes 12 et est disproportionnée par rapport à celle-ci. Le collecteur 14 et les joints ou garnitures d'étanchéité coopérant avec le collecteur 14 et avec le rebord périphérique de la face ouverte de la boîte à eau 10 ont nécessairement une dimension en largeur correspondant à celle de la boîte à eau 10. On est donc conduit dans la technique antérieure, lorsqu'on veut loger un radiateur d'huile 16 à l'intérieur d'une boîte à eau 10, à utiliser une boîte à eau, un collecteur et des garnitures d'étanchéité d'un type spécial, ce qui est désavantageux d'un point de vue économique.For this assembly to be possible, the internal width L of the water box 10 must be substantially equal to the size 1 of the radiator 16 in width, constituted by the outside diameter of its outer cylindrical wall 18 and the length of the pipes. 22. The width L of the water box 10 is thus much greater than the corresponding dimension d of the bundle of tubes 12 and is disproportionate with respect thereto. The manifold 14 and the seals or seals cooperating with the manifold 14 and with the peripheral rim of the open face of the water box 10 necessarily have a width dimension corresponding to that of the water box 10. It is therefore leads in the prior art, when it is desired to house an oil radiator 16 inside a water box 10, to use a water box, a manifold and seals of a special type, which is disadvantageous from an economic point of view.

On se réfère maintenant aux figures 2 et 4, représentant une boîte à eau selon l'invention.We now refer to Figures 2 and 4, showing a water box according to the invention.

Cette boîte à eau 34 est montée à l'extrémité du faisceau de tubes 12 par un collecteur 36 usuel, identique à celui qui serait utilisé pour la fixation d'une boîte à eau ordinaire ne contenant pas le radiateur d'huile 16. En d'autres termes, la boîte à eau 34 selon l'invention a une largeur interne L' égale à celle d'une boîte à eau usuelle correspondant à la dimension d du faisceau de tubes 12 et ne contenant pas de radiateur d'huile.This water box 34 is mounted at the end of the bundle of tubes 12 by a conventional manifold 36, identical to that which would be used for fixing an ordinary water box not containing the oil radiator 16. In d In other words, the water box 34 according to the invention has an internal width L ′ equal to that of a usual water box corresponding to the dimension d of the bundle of tubes 12 and not containing an oil radiator.

La paroi latérale 48 de la boîte à eau 34, qui est traversée par les tubulures du radiateur d'huile, comprend deux ouvertures circulaire 52, dont l'une est représentée dans la partie droite de la figure 4, chaque ouverture 52 étant limitée par un rebord périphérique annulaire plan 54 et ayant une dimension suffisante pour permettre le débattement d'une tubulure 22 du radiateur 16 lorsque celui-ci est introduit dans la boîte à eau 34 par la face ouverte 56 de celle-ci, les tubulures 22 étant alors orientées verticalement vers le haut, puis inclinées en oblique en direction des ouvertures 52 au fur et à mesure que le radiateur 16 est introduit dans la boîte à eau, pour finir dans la disposition représentée en figure 2.The side wall 48 of the water box 34, which is crossed by the pipes of the oil radiator, comprises two circular openings 52, one of which is shown in the right part of FIG. 4, each opening 52 being limited by a plane annular peripheral rim 54 and having a dimension sufficient to allow the deflection of a pipe 22 of the radiator 16 when the latter is introduced into the water box 34 through the open face 56 thereof, the pipes 22 then being oriented vertically upwards, then inclined obliquely towards the openings 52 as the radiator 16 is introduced into the water box, to finish in the arrangement shown in FIG. 2.

Chaque ouverture 52 de la boîte à eau est destinée à être fermée par une plaque rapportée 58, de forme circulaire, dont le diamètre externe est sensiblement égal à celui du rebord périphérique 54 de l'ouverture 52. Chaque plaque circulaire 58 est formée avec un orifice de passage de la partie d'extrémité filetée d'une tubulure 22 du radiateur d'huile.Each opening 52 of the water box is intended to be closed by an attached plate 58, of circular shape, the external diameter of which is substantially equal to that of the peripheral rim 54 of the opening 52. Each circular plate 58 is formed with a orifice for the passage of the threaded end portion of a pipe 22 of the oil radiator.

Lorsque le radiateur 16 est disposé à l'intérieur de la boite à eau 34 de la façon précitée, les plaques 58 sont enfilées sur les extrémités des tubulures 22 avec interposition d'un joint d'étanchéité. Les écrous 30 sont vissés sur les extrémités des tubulures et viennent serrer les plaques 58 contre les brides ou rebords annulaires 26 des tubulures. Ensuite, les plaques 58 sont fixées à leur périphérie sur les rebords annulaires 54 des ouvertures 52, par soudure par ultrason, par collage ou tout autre moyen approprié.When the radiator 16 is placed inside the water box 34 in the aforementioned manner, the plates 58 are threaded onto the ends of the pipes 22 with the interposition of a seal. The nuts 30 are screwed onto the ends of the pipes and tighten the plates 58 against the annular flanges or flanges 26 of the pipes. Then, the plates 58 are fixed at their periphery to the annular edges 54 of the openings 52, by ultrasonic welding, by gluing or any other suitable means.

Les brides ou rebords 26 des tubulures ont un diamètre inférieur à celui des ouvertures 52, ce qui permet de disposer facilement le radiateur d'huile dans une boîte à eau de largeur normale.The flanges or flanges 26 of the pipes have a diameter smaller than that of the openings 52, which makes it possible to easily place the oil radiator in a water box of normal width.

Le fait que le radiateur d'huile ait une forme générale cylindrique facilite également cette disposition.The fact that the oil radiator has a generally cylindrical shape also facilitates this arrangement.

Si nécessaire, on peut prévoir que les ouvertures 52 de la paroi de la boîte à eau ont une forme non circulaire et qu'elles peuvent s'étendre sur la paroi de sommet de la boite à eau.If necessary, provision can be made for the openings 52 of the wall of the water box have a non-circular shape and that they can extend over the top wall of the water box.

De façon générale, il suffit que la plus grande dimension transversale du corps du radiateur d'huile soit inférieure à la largeur de la face ouverte de la boîte à eau pour que ce radiateur puisse être disposé sans difficultés dans la boîte à eau.In general, it is sufficient that the largest transverse dimension of the body of the oil radiator is less than the width of the open face of the water box so that this radiator can be disposed without difficulty in the water box.
