Description

La présente invention concerne les radiateurs, particulierement pour installations de climatisation de véhicules automobiles, ou pour le refroidissement des moteurs de véhicules automobiles. The present invention relates to radiators, particularly for air conditioning systems of motor vehicles, or for the cooling of motor vehicle engines.

En particulier, l'invention concerne un radiateur du type comprenant
- une série de tubes à section circulaire,
- une série de plaques superposées, séparées.les unes des autres et traversées par lesdits tubes
- une plaque d'extrémité présentant une série d'orifices munis de collets dans lesquels s'engageant les ex extrémités élargies desdits tubes,
- un couvercle fixé sur ladite plaque d'extrémité de façon à définir une chambre collectrice,
- une garniture d'étanchéité à membrane avec un bord périphérique interpose entré le bord de la plaque d'extrémité et le couvercle, et une série d'orifices munis de bords renforcés, ces bords renforcés étant interposés entre les tubes et les collets de la plaque d'extrémité.In particular, the invention relates to a radiator of the type comprising
- a series of circular section tubes,
- a series of superimposed plates, separated from each other and crossed by said tubes
an end plate having a series of orifices provided with collars in which the ex widened ends of the said tubes engage,
- a cover fixed on said end plate so as to define a collecting chamber,
- a membrane seal with a peripheral edge interposed between the edge of the end plate and the cover, and a series of orifices provided with reinforced edges, these reinforced edges being interposed between the tubes and the collars of the end plate.

Un radiateur du type spécifié ci-dessus est décrit et illustré dans le brevet français NO 1 577 223. Dans ce radiateur connu, les orifices de la garniture d'étanchéité à membrane sont munis de collets qui sont interposés entre les collets de la plaque d'extrémité et les tubes du radiateur de manière a' empêcher un contact direct entre ces éléments. Par conséquent, les- collets de la garniture d'étanchéité sont soumis aux sollicitations mécaniques qui s'exercent entre les tubes du radiateur et les collets de la plaque d'extrémité. En outre, ladite garniture d'étanchéité est directement en contact avec le liquide présent dans la chambre collectrice du radiateur, ce qui risque de provoquer l'érosion de cette garniture.Par ailleurs, s'il se produit une dépression à l'intérieur de la chambre collectrice, par exemple à la suite d'un refroidissement, les collets de la garniture d'étanchéité sont sollicités en traction.  A radiator of the type specified above is described and illustrated in French Patent No. 1,577,223. In this known radiator, the orifices of the membrane seal are provided with collars which are interposed between the collars of the plate d end and tubes of the radiator so as to prevent direct contact between these elements. Consequently, the collars of the seal are subjected to the mechanical stresses which are exerted between the tubes of the radiator and the collars of the end plate. In addition, said seal is in direct contact with the liquid present in the manifold of the radiator, which risks causing erosion of this seal. Furthermore, if there is a vacuum inside the collecting chamber, for example following cooling, the collars of the seal are stressed in tension.

Le but de la présente invention est d'éviter ces inconvénients en réalisant un radiateur qui présente des caractéristiques perfectionnées de résistance et de facilité et rapidité de montage. The object of the present invention is to avoid these drawbacks by producing a radiator which has improved characteristics of resistance and of ease and speed of assembly.

Pour atteindre ce but, l'invention a pour objet un radiateur du type spécifié au début, caractérisé par le fait -que lesdits collets de la plaque d'extrémité présentent, chacun, une partie d'extrémité en contact direct avec le tube correspondant et une partie de base, d'un diamètre élargi, à l'intérieur de laquelle est reçu le bord respectif renforcé de la garniture d'étanchéité, ainsi que par le fait que ce radiateur comprend aussi une plaque métallique presse-garniture disposée sur le côté de la garniture d'étanchéité tourné vers la chambre collectrice et présentant, elle aussi, une série d'orifices dans lesquels s'engagent les extrémités élargies des tubes du radiateur, ladite garniture d'étanchéité étant estampée di rectetient sur la plaque presse-garniture. To achieve this object, the invention relates to a radiator of the type specified at the start, characterized by the fact that said collars of the end plate each have an end part in direct contact with the corresponding tube and a base part, of an enlarged diameter, inside which is received the respective reinforced edge of the gasket, as well as by the fact that this radiator also comprises a metal gasket plate disposed on the side of the seal facing the collecting chamber and also having a series of holes in which the enlarged ends of the radiator tubes engage, said seal being stamped di rectetient on the packing plate .

Etant donné que le radiateur selon l'invention est conçu de manière à ce que les collets de la plaque d'extrémité et les tubes correspondants soient en contact direct les uns avec les autres, ces éléments échangent directement entre eux les sollicitations qui s'exercent pendant l'utilisation du radiateur, sans que ces sollicitations soient transmises à la garniture d'étanchéité. Since the radiator according to the invention is designed so that the collars of the end plate and the corresponding tubes are in direct contact with each other, these elements exchange directly between them the stresses which are exerted during the use of the radiator, without these stresses being transmitted to the seal.

En outre, la plaque presse-earni'ure qui couvre la garniture d'étanchéité sur le côté tourné vers la chambre collectrice protège cette garniture contre le risque d'une érosion provoquée par le liquide circulant dans la chambre collectrice. In addition, the press-earn plate which covers the seal on the side facing the collecting chamber protects this packing against the risk of erosion caused by the liquid circulating in the collecting chamber.

Ladite plaque presse-garniture a également pour fonction d'empêcher que les bords renforcés des orifices de la garniture d'étanchéité soient sollicités en traction dans le cas où il se produirait une dépression à l'intérieur de la chambre collectrice. Ladite plaque presse-garniture est, en effet, pressee contre la garriture par les extrémités élargies des tubes du radiateur. Said stuffing plate also has the function of preventing the reinforced edges of the orifices of the sealing gasket from being subjected to tensile stress in the event that there is a vacuum inside the collecting chamber. Said stuffing box plate is, in fact, pressed against the packing by the enlarged ends of the radiator tubes.

Un autre avantage du radiateurselon l'invention réside dans le fait que la plaque presse-garniture sur laquelle la garniture est directement estampée confère une bonne stabilité dimensionnelle à ladite garniture, facilitant ainsi son transport et son stockage et permettant de la monter rapidement et de façon précise. Another advantage of the radiator according to the invention lies in the fact that the packing plate on which the packing is directly stamped confers a good dimensional stability on said packing, thus facilitating its transport and its storage and allowing to assemble it quickly and so precise.

D'autres caractéristiques et avantages de lein- vention seront mis en évidence par la description donnée ci-après en- se référant aux dessins ci-joints, fournis uniquement à titre d'exemple non limitatif et sur lesquels
la Fig. 1 est une vue en perspective, schématique, d'un radiateur selon l'invention dont le couvercle est représenté, pour des raisons de clarté, en position démontée.Other characteristics and advantages of the invention will be highlighted by the description given below with reference to the attached drawings, provided solely by way of non-limiting example and in which
Fig. 1 is a schematic perspective view of a radiator according to the invention, the cover of which is shown, for reasons of clarity, in the disassembled position.

- la Fig. 2 est une vue en coupe d'un détail de' la figure 1, avec le couvercle en position montée. - Fig. 2 is a sectional view of a detail of 'Figure 1, with the cover in the mounted position.

- la Fig. 3 est une vue à une échelle agrandie d'un détail de la figure 2. - Fig. 3 is a view on an enlarged scale of a detail of FIG. 2.

Sur la figure 1, la référence 1 désigne dans son ensemble un radiateur utilisable pour installations de climatisation de véhicules automobiles. L'invention est également applicable aux radiateurs pour le refroidissement des moteurs de véhicules automobiles. In FIG. 1, the reference 1 designates as a whole a radiator which can be used for air conditioning installations of motor vehicles. The invention is also applicable to radiators for cooling the engines of motor vehicles.

Le radiateur 1 comprend une série de tubes 2 à section circulaire qui traversent une série de plaques 3 superposées et séparées lea unes des autres. The radiator 1 comprises a series of tubes 2 of circular section which pass through a series of plates 3 superimposed and separated from each other.

La référence 4 désigne une plaque d'extrémité présentant une série d'orifices 5 munis decollets 6 (voir figures 2 et 3) à l'intérieur desquels s'engagent les ex- ,.  The reference 4 designates an end plate having a series of orifices 5 provided with collars 6 (see FIGS. 2 and 3) inside which the ex-, engage.

trémités élargies des'tubes 2. Ces extrémités sont rendues solidaires de la plaque d'extrémité 4 par simple expansion mécanique.widened hoppers of the tubes 2. These ends are made integral with the end plate 4 by simple mechanical expansion.

Sur la plaque d'extrémité 4 est fixe un couvercle 7 qui définit une chambre collectrice 8. Cette chambre est divisée en deux compartiments Sa, 8b, par une cloison intérieure 9 du couvercle 7, lesdits compartiments communiquant respectivement avec un raccord d'entrée 10 et avec un raccord de sortie 11.Le radiateur représenté à titre d'exemple sur les dessins ci-joints est, en effet, du type avec circulation en U, dans lequel les tubes 2 communiquent entre eux deux par deux au niveau des extrémités opposées à celles représentées sur la figure 2 7 de sorte que le liquide qui entre dans le compartiment Sa à travers le raccord d'entrée 10 parcourt les tubes 2 qui communiquent avec ce compartiment jusqu'à atteindre l'extrémité opposée du radiateur, passe par les tubes restants et sort du ra- diateur à travers le compartiment 8b et le raccord de sortie 11. On the end plate 4 is fixed a cover 7 which defines a collecting chamber 8. This chamber is divided into two compartments Sa, 8b, by an internal partition 9 of the cover 7, said compartments communicating respectively with an inlet connector 10 and with an outlet connector 11. The radiator shown by way of example in the attached drawings is, in fact, of the type with U-shaped circulation, in which the tubes 2 communicate with each other in pairs at the opposite ends to those shown in FIG. 27 so that the liquid which enters the compartment Sa through the inlet connector 10 passes through the tubes 2 which communicate with this compartment until reaching the opposite end of the radiator, passes through the remaining tubes and out of the radiator through compartment 8b and outlet fitting 11.

Bien entendu, l'invention est également applicable aux radiateurs dans lesquels les raccords d'entrée et de sortie pour le fluide circulant dans le radiateur sont disposés sur les extrémités opposées de ce dernier. Of course, the invention is also applicable to radiators in which the inlet and outlet connections for the fluid flowing in the radiator are arranged on the opposite ends of the latter.

Le bord du couvercle 7 est fixé - de façon déjà connue - sur la plaque d'extrémité -4 grâce au pliage d'appendices périphériques 12 de la plaque d'extrémité 4. The edge of the cover 7 is fixed - in a manner already known - to the end plate -4 by folding peripheral appendages 12 of the end plate 4.

Le radiateur 1 comprend, en outre, une garniture d'étanchéité à membrane 13 présentant un bord périphérique 14 interposé entre le bord de la plaque d'extrémité 4 et le couvercle 7. The radiator 1 further comprises a membrane seal 13 having a peripheral edge 14 interposed between the edge of the end plate 4 and the cover 7.

La garniture d'étanchéité à membrane 13 pré-sente également une série d'orifices 15 munis de bords renforcés 16. The membrane seal 13 also has a series of orifices 15 provided with reinforced edges 16.

Chaque collet de la plaque d'extrémité 4 comprend une partie d'extrémité 6a en contact direct avec le tube- 2 correspondant et une partie de base 6b, d'un diamètre élargi. chacun desdits bords renforcés 16 de la garniture d'é tanchéité à membrane 13 est interposé entre un tube 2 et la partie de base 6b du collet 6 correspondant de la plaque d'extrémité 4. Each collar of the end plate 4 comprises an end part 6a in direct contact with the corresponding tube 2 and a base part 6b, of an enlarged diameter. each of said reinforced edges 16 of the membrane seal 13 is interposed between a tube 2 and the base part 6b of the corresponding collar 6 of the end plate 4.

La référence 17 désigne une plaque métallique presse-garniture disposée sur le côté de la garniture d'étan chéité 13 qui est tourné vers la chambre collectrice 8. The reference 17 designates a metal packing-gland plate placed on the side of the sealing gasket 13 which faces the collecting chamber 8.

La plaque presse-garnitur-e 17 présente, elle aussi, une série d'orifices 18 dans lesquels s'engagent les extrémités élargies des tubes 2 du radiateur. La garniture d'étanchéité à membrane 13 est assemblée avec la plaque presse-garniture 17 par estampage direct sur cette plaque. Pour améliorer l'assemblage de la plaque 17 avec la garniture 13, cette dernière est munie d'appendices 19qui s'insèrent dans des orifices respectifs auxiliaires 20 de la plaque presse-garniture 17. The press-packing plate 17 also has a series of orifices 18 into which the enlarged ends of the tubes 2 of the radiator engage. The membrane seal 13 is assembled with the packing plate 17 by direct stamping on this plate. To improve the assembly of the plate 17 with the lining 13, the latter is provided with appendages 19 which are inserted in respective auxiliary orifices 20 of the packing-plate 17.

Pour procéder au montage, la première opération consiste à fixer la plaque d'extrémité 4 aux tubes 2, par expansion mécanique des parties d'extrémité (désignées par 2a) de ces tubes, de façon à les maintenir accouplées avec les parties d'extrémité 6a des collets de la plaque d'extrémité 4. La deuxième opération consiste à monter la garniture d'étanchéité 13 avec la plaque 17 solidaire de celle-c-i et, enfin, il est réalisé une expansion mécanique de la partie d'extrémité 2b des tubes 2, de manière à fixer la plaque 17 aux tubes 2 et à presser cette plaque contre la garniture 13. To carry out the assembly, the first operation consists in fixing the end plate 4 to the tubes 2, by mechanical expansion of the end parts (designated by 2a) of these tubes, so as to keep them coupled with the end parts. 6a of the collars of the end plate 4. The second operation consists in mounting the seal 13 with the plate 17 integral with the latter and, finally, there is produced a mechanical expansion of the end part 2b of the tubes 2, so as to fix the plate 17 to the tubes 2 and to press this plate against the lining 13.

Le contact direct entre les tubes 2 et les collets 6 de la plaque d'extrémité 4 permet -d'éviter que les sollicitations mécaniques entre ces éléments soient transmises à la garniture d'étanchéité 13. En outre, la plaque presse-garniture 17 protège la garniture 13 contre le risque d'une érosion provoquée par le liquide circulant dans la chambre collectrice 8. La plaque 17 empêche aussi que les bords renforcés 16 de la garniture 13 soient sollicités en traction au cas où il se produirait une dépression dans la chambre collectrice. Enfin, la plaque presse-gar- niture 17 confère une bonne stabilité dimensionnelle à la garniture d'étanchéité à membrane 13, facilitant ainsi son transport et son stockage et permettant de la monter rapi- dement et de façon précise.  Direct contact between the tubes 2 and the collars 6 of the end plate 4 makes it possible to avoid the mechanical stresses between these elements being transmitted to the seal 13. In addition, the seal plate 17 protects the lining 13 against the risk of erosion caused by the liquid flowing in the collecting chamber 8. The plate 17 also prevents the reinforced edges 16 of the lining 13 from being subjected to tensile stress in the event that a depression occurs in the chamber collector. Finally, the packing plate 17 gives good dimensional stability to the membrane seal 13, thus facilitating its transport and storage and allowing it to be mounted quickly and precisely.
