Description

La présente invention concerne une liaison d'une joue sur un échangeur de chaleur, notamment radiateur de refroidissement pour véhicule automobile.The present invention relates to a connection of a cheek on a heat exchanger, in particular a cooling radiator for a motor vehicle.

Habituellement, un échangeur de chaleur comporte au moins une boîte collectrice de fluide dans laquelle débouche, à étanchéité, un faisceau de tubes munis d'ailettes disposées, soit perpendiculairement au sens longitudinal des tubes en étant fixées à ceux-ci par brasage ou assemblage mécanique, soit parallèlement au même sens en étant fixées à ceux-ci par brasage.Usually, a heat exchanger comprises at least one fluid collecting box into which opens, with sealing, a bundle of tubes provided with fins arranged either perpendicular to the longitudinal direction of the tubes by being fixed to them by brazing or mechanical assembly. , or parallel to the same direction by being fixed thereto by soldering.

Dans la demande de brevet n° 69 31035 publiée le 12 février 1971, il est fait mention de rapporter des parties latérales ou joues sur les bords latéraux du faisceau de tubes et de fixer celles-ci sur lesdits bords au moyen d'une pâte adhésive de préférence en résine époxy qui, après séchage, procure une liaison rigide entre le bord latéral du faisceau et la joue servant à supporter et à maintenir des organes accessoires liés à l'échangeur, tels que le ventilateur de refroidissement, et/ou à fixer le radiateur sur le véhicule.In patent application No. 69 31035 published on February 12, 1971, mention is made of attaching lateral or cheek portions to the lateral edges of the tube bundle and of fixing these on said edges by means of an adhesive paste. preferably made of epoxy resin which, after drying, provides a rigid connection between the lateral edge of the bundle and the cheek used to support and maintain accessory members linked to the exchanger, such as the cooling fan, and / or to fix the radiator on the vehicle.

Cette disposition présente néanmoins l'inconvénient de lier rigidement la joue avec le faisceau et les vibrations produites, soit par le véhicule en fonctionnement dans le cas où le radiateur est fixé sur le véhicule par les joues, soit par les organes liés à l'échangeur, sont transmises directement au faisceau de tubes à ailettes et peuvent endommager celui-ci, et plus particulièrement au niveau des fixations des ailettes sur les tubes ou au niveau de la fixation étanche des tubes dans la boîte collectrice de fluide.This arrangement nevertheless has the drawback of rigidly linking the cheek with the beam and the vibrations produced, either by the vehicle in operation in the case where the radiator is fixed to the vehicle by the cheeks, or by the members linked to the exchanger. , are transmitted directly to the bundle of finned tubes and can damage the latter, and more particularly at the level of the attachments of the fins on the tubes or at the level of the sealed attachment of the tubes in the fluid collecting box.

En outre le faisceau de tubes à ailettes subit, en fonctionnement, de fortes dilatations longitudinales et plus particulièrement au niveau des tubes sur lesquels sont fixées les ailettes qui sont reliées rigidement, en outre, à une de leurs extrémités sur la joue par la résine époxy.In addition, the finned tube bundle undergoes large longitudinal expansions during operation and more particularly at the level of the tubes on which the fins are fixed, which are rigidly connected, in addition, to one of their ends on the cheek by the epoxy resin. .

Ainsi, lors de la dilatation longitudinale des tubes, les parties d'ailettes fixées sur lesdits tubes suivent cette dilatation alors que les extrémités fixées sur la joue restent fixes, ce qui entraîne un fléchissement des parties d'ailettes comprises entre le tube sur lequel elles sont fixées et la joue, ce fléchissement pouvant entraîner, du fait de la liaison rigide de ladite joue avec les extrémités des ailettes, une déchirure desdites ailettes au niveau du collage sur ladite joue.Thus, during the longitudinal expansion of the tubes, the parts of fins fixed on said tubes follow this expansion while the ends fixed on the cheek remain fixed, which causes a deflection of the parts of fins included between the tube on which they are fixed and the cheek, this sagging being able to cause, due to the rigid connection of said cheek with the ends of the fins, a tear of said fins at the level of bonding on said cheek.

La présente invention a pour but de remédier à ces inconvénients et propose, à cet effet, une liaison entre la joue et le faisceau de tubes à ailettes de conception simple tout en procurant une liaison fiable entre ceux-ci.The present invention aims to remedy these drawbacks and proposes, for this purpose, a connection between the cheek and the bundle of finned tubes of simple design while providing a reliable connection between them.

Suivant l'invention, la liaison d'une joue sur un échangeur de chaleur, notamment radiateur de refroidissement pour véhicule automobile, comportant au moins une boîte collectrice de fluide dans laquelle débouche à étanchéité un faisceau de tubes à ailettes dont au moins un bord latéral est muni d'au moins une joue, est caractérisée en ce que la joue est liée au bord latéral du faisceau de tubes à ailettes par un mastic souple.According to the invention, the connection of a cheek on a heat exchanger, in particular a cooling radiator for a motor vehicle, comprising at least one fluid collecting box into which a bundle of finned tubes opens, with at least one lateral edge is provided with at least one cheek, is characterized in that the cheek is linked to the lateral edge of the bundle of finned tubes by a flexible sealant.

Grâce à ce mastic souple les vibrations transmises à la joue sont absorbées par le mastic formant coussin anti-vibratoire.Thanks to this flexible sealant, the vibrations transmitted to the cheek are absorbed by the sealant forming an anti-vibration cushion.

Suivant une autre caractéristique, la joue est disposée à distance du bord latéral du faisceau de tubes à ailettes.According to another characteristic, the cheek is arranged at a distance from the lateral edge of the bundle of finned tubes.

Ainsi cette disposition empêche non seulement la transmission des vibrations, mais permet un certain débattement de l'extrémité de l'ailette dans le mastic souple.Thus this arrangement not only prevents the transmission of vibrations, but allows a certain movement of the end of the fin in the flexible sealant.

Les autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple, en se référant aux dessins annexés sur lesquels :

  • - la figure 1 est une vue d'ensemble d'un échangeur de chaleur;
  • - la figure 2 est une vue de détail montrant la liaison suivant l'invention.
The other characteristics and advantages of the invention will emerge from the description which follows, given by way of example, with reference to the appended drawings in which:
  • - Figure 1 is an overview of a heat exchanger;
  • - Figure 2 is a detail view showing the connection according to the invention.

Sur la figure 1 l'échangeur de chaleur 1, ici un radiateur de refroidissement, comprend au moins une boîte collectrice de fluide, ici deux, 2, 3, dans chacune desquelles débouche à étanchéité, une extrémité d'un faisceau 4 de tubes 5 munis d'ailettes 6. Ces tubes 5 sont pourvus, ici, d'ailettes ondulées 6 disposées parallèlement au sens longitudinal desdits tubes en étant fixées à ceux-ci par brasage, par exemple, mais on ne sortirait pas du cadre de l'invention en disposant des ailettes planes perpendiculairement au sens longitudinal des tubes 5 et en fixant celles-ci par assemblage mécanique ou par brasage.In FIG. 1 the heat exchanger 1, here a cooling radiator, comprises at least one fluid collecting box, here two, 2, 3, in each of which opens with sealing, one end of a bundle 4 of tubes 5 provided with fins 6. These tubes 5 are provided, here, with corrugated fins 6 arranged parallel to the longitudinal direction of said tubes by being fixed thereto by brazing, for example, but it would not depart from the scope of the invention by having flat fins perpendicular to the longitudinal direction of the tubes 5 and by fixing them by mechanical assembly or by brazing.

C'est sur le faisceau 4 et plus particulièrement sur au moins un de ses bords latéraux, ici les deux, 7, qu'est rapportée au moins une joue 8 pour y être reliée audit faisceau.It is on the beam 4 and more particularly on at least one of its lateral edges, here the two, 7, that at least one cheek 8 is attached in order to be connected to said beam.

Comme mieux visible sur la figure, les joues 8 sont aptes à porter des pattes 10,11 saillantes à partir desdites joues et pouvant servir à la fixation d'un organe lié à l'échangeur, tel qu'un support servant à la réception d'un moteur électrique actionnant un ventilateur et/ou à la fixation du radiateur sur le véhicule.As best seen in the figure, the cheeks 8 are capable of carrying tabs 10, 11 projecting from the said cheeks and which can be used for fixing a member linked to the exchanger, such as a support used for the reception of '' an electric motor driving a fan and / or fixing the radiator to the vehicle.

Comme mieux visible sur la figure et suivant l'invention, la joue 8 est fixée au bord latéral 7 du faisceau de tubes à ailettes par un mastic souple 9.As best seen in the figure and according to the invention, the cheek 8 is fixed to the lateral edge 7 of the bundle of finned tubes by a flexible mastic 9.

Ce mastic est un mastic à base de polysulfure à deux composants tel que celui commercialisé sous la dénomination "Scotch Seul" qui, après prise, donne une certaine souplesse ainsi qu'une élasticité audit mastic.This sealant is a two-component polysulfide sealant such as that sold under the name "Scotch Alone" which, after setting, gives a certain flexibility as well as an elasticity to said sealant.

Ainsi ce mastic adhère, d'une part, à la face 13 de la joue 8 tournée vers le bord 7 et, d'autre part, sur l'extrémité 14 de l'ailette ondulée 6 formant ledit bord.Thus this mastic adheres, on the one hand, to the face 13 of the cheek 8 facing the edge 7 and, on the other hand, on the end 14 of the corrugated fin 6 forming said edge.

En pratique, pour assurer une bonne liaison, il est prévu que le mastic 9 pénètre au-delà du bord 7, matérialisé sur la figure par un trait mixte, en englobant une certaine partie de l'extrémité 14 de l'ailette 6.In practice, to ensure a good connection, provision is made for the mastic 9 to penetrate beyond the edge 7, materialized in the figure by a dashed line, encompassing a certain part of the end 14 of the fin 6.

De plus, afin d'éviter le contact métal-métal entre la joue 8 et le bord 7, contact générateur de bruits et de transmission de vibrations, ladite joue est disposée à distance D du bord 7 et l'espace ainsi créé est comblé au moins en partie par le mastic souple 9, ici en totalité.In addition, in order to avoid metal-metal contact between the cheek 8 and the edge 7, a noise-generating and vibration-transmitting contact, said cheek is disposed at a distance D from the edge 7 and the space thus created is filled in. less in part by the flexible mastic 9, here entirely.

Pour réaliser cette liaison il suffit de disposer, soit sur la face 13 de la joue 8, soit sur le bord 7 du faisceau 4, dans l'exemple décrit, sur l'extrémité 14 de l'ailette 6, le mastic souple 9 sous forme d'au moins un cordon ou sous forme d'un ruban et de rapprocher la joue 8 vers le bord 7 de façon à ce que, si le mastic est sous forme de cordon, d'écraser ledit cordon de façon à ce que celui-ci se transforme en un ruban et, une fois cette forme atteinte, de rapprocher la joue 8 du bord 7 de façon à ce que le mastic 9 pénètre au-delà du bord 7.To make this connection, it suffices to have, either on the face 13 of the cheek 8, or on the edge 7 of the bundle 4, in the example described, on the end 14 of the fin 6, the flexible mastic 9 under form at least one bead or in the form of a ribbon and bring the cheek 8 towards the edge 7 so that, if the putty is in the form of a cord, crush the said cord so that the -this turns into a ribbon and, once this shape has been reached, bring the cheek 8 closer to the edge 7 so that the putty 9 penetrates beyond the edge 7.

Si, à l'origine, le mastic est déposé sous forme de ruban, il suffit simplement de rapprocher la joue 8 de façon à obtenir une pénétration du mastic au-delà du bord 7.If, at the outset, the putty is deposited in the form of a ribbon, it is sufficient to bring the cheek 8 together so as to obtain penetration of the putty beyond the edge 7.

Une fois cette configuration atteinte, il suffit de polymériser le mastic à température ambiante ou, de préférence, d'accélérer le processus en polymérisant à chaud, telle qu'avec une température d'environ 60°C.Once this configuration is reached, it suffices to polymerize the sealant at room temperature or, preferably, to accelerate the process by polymerizing under heat, such as with a temperature of approximately 60 ° C.
