  • la figure 5 est une vue partielle en élévation du radiateur;
  • la figure 6 est une vue partielle de dessus; et
  • la figure 7 est une vue partielle en coupe transversale du radiateur.
The characteristics and advantages of the invention will be explained in more detail in the description below, with reference to the accompanying drawings, in which:
  • Figures 1 to 4 are partial perspective views of a cooling radiator according to the invention, from different angles;
  • Figure 5 is a partial elevational view of the radiator;
  • Figure 6 is a partial top view; and
  • Figure 7 is a partial cross-sectional view of the radiator.

Le radiateur partiellement illustré, destiné au refroidissement d'un fluide caloporteur qui recueille la chaleur dégagée par le moteur thermique d'entraînement d'un véhicule automobile, comprend une rangée de tubes 1 pour la circulation de ce fluide. Les tubes 1 sont allongés dans une même direction horizontale, et mutuellement alignés dans la direction verticale. Ils présentent une section transversale aplatie dont la longueur et l'épaisseur sont orientées respectivement horizontalement et verticalement. Les tubes 1 sont maintenus écartés les uns des autres par des ailettes ou intercalaires 2 sous forme de bandes de tôle ondulées à la manière d'une sinusoïde, les crêtes d'ondulation d'un même intercalaire venant alternativement en contact avec deux tubes voisins de la rangée. Le tube situé à l'extrémité supérieure de la rangée est maintenu écarté, par un intercalaire 2 semblable aux précédents, d'une joue profilée 3 allongée parallèlement à la direction longitudinale des tubes, appelée ci-après simplement "direction longitudinale". La joue 3 est formée par une bande de tôle d'environ 0,5 mm d'épaisseur, pliée selon des lignes longitudinales pour former une semelle sensiblement plane 4, s'appuyant sur les crêtes de l'intercalaire 2, et deux nervures 5 s'écartant de la semelle à l'opposé de l'intercalaire 2 et par conséquent des tubes 1. Les deux nervures 5 sont disposées au voisinage respectivement des deux bords latéraux 6 de la joue 3, lesquels bords latéraux sont situés respectivement dans les mêmes deux plans verticaux que les tranches opposées 7 des intercalaires 2, ces deux plans, parallèles à la direction longitudinale et à la direction d'alignement des tubes, définissant deux faces principales du radiateur.The partially illustrated radiator, intended for cooling a heat transfer fluid which collects the heat released by the heat engine driving a motor vehicle, comprises a row of tubes 1 for the circulation of this fluid. The tubes 1 are elongated in the same horizontal direction, and mutually aligned in the vertical direction. They have a flattened cross section whose length and thickness are oriented respectively horizontally and vertically. The tubes 1 are kept apart from each other by fins or spacers 2 in the form of strips of corrugated sheet metal in the manner of a sinusoid, the corrugation ridges of the same spacer alternately coming into contact with two neighboring tubes of the row. The tube located at the upper end of the row is kept apart, by an insert 2 similar to the previous ones, from a profiled cheek 3 elongated parallel to the longitudinal direction of the tubes, hereinafter simply called "longitudinal direction". The cheek 3 is formed by a strip of sheet metal about 0.5 mm thick, folded along longitudinal lines to form a substantially flat sole 4, resting on the ridges of the interlayer 2, and two ribs 5 deviating from the sole opposite the interlayer 2 and consequently from the tubes 1. The two ribs 5 are disposed in the vicinity respectively of the two lateral edges 6 of the cheek 3, which lateral edges are located respectively in the same two vertical planes as the opposite edges 7 of the inserts 2, these two planes, parallel to the longitudinal direction and to the direction of alignment of the tubes, defining two main faces of the radiator.

De façon connue, le radiateur peut comprendre en outre deux boîtes à fluide dans lesquelles débouchent respectivement les deux extrémités de chacun des tubes 1, ainsi qu'une seconde joue semblable à la joue 6 placée à l'extrémité inférieure du faisceau formé par les tubes 1 et les intercalaires 2. Les tubes 1, les intercalaires 2, la joue 3 et le cas échéant les deux boîtes à fluide et la joue inférieure sont mutuellement assemblés par brasage pour former un bloc rigide.In known manner, the radiator may further comprise two fluid boxes into which the two ends of each of the tubes 1 open respectively, as well as a second cheek similar to the cheek 6 placed at the lower end of the bundle formed by the tubes. 1 and the inserts 2. The tubes 1, the inserts 2, the cheek 3 and, where appropriate, the two fluid boxes and the bottom cheek are mutually assembled by brazing to form a rigid block.

Sur ce bloc est monté un support 8 constitué, selon l'invention, par une pièce unique en tôle métallique découpée et pliée. Le support 8, allongé dans la direction longitudinale, comporte un dos sensiblement plan 9 qui s'appuie sur les crêtes des deux nervures 5, le dos 9 se raccordant à deux flasques longitudinaux 10 et 11 pliés sensiblement à angle droit en direction du faisceau, en regard des deux faces principales de celui-ci respectivement. Le flasque 10 s'étend sur toute la longueur du support, tandis que le flasque 11 est en deux parties adjacentes respectivement aux deux extrémités du support. Entre ces deux parties, le dos 9 se raccorde à une patte 12 en forme de L dont une branche 13 le prolonge latéralement, sensiblement dans son propre plan, l'autre branche 14 étant repliée à angle droit par rapport à la première pour s'étendre en regard de la face principale correspondante du bloc. Une zone centrale de la branche 14 est repoussée en direction du bloc pour former un collet taraudé 15.On this block is mounted a support 8 constituted, according to the invention, by a single piece of cut sheet metal and folded. The support 8, elongated in the longitudinal direction, has a substantially flat back 9 which rests on the crests of the two ribs 5, the back 9 connecting to two longitudinal flanges 10 and 11 folded substantially at right angles to the beam, opposite the two main faces thereof respectively. The flange 10 extends over the entire length of the support, while the flange 11 is in two parts adjacent respectively to the two ends of the support. Between these two parts, the back 9 is connected to an L-shaped tab 12 of which a branch 13 extends it laterally, substantially in its own plane, the other branch 14 being folded at right angles to the first for extend opposite the corresponding main face of the block. A central zone of the branch 14 is pushed back towards the block to form a threaded collar 15.

Dans chacune des deux régions du dos 8 adjacentes aux deux parties du flasque 11 sont formées plusieurs languettes embouties 16, allongées dans la direction latérale du dos et mutuellement alignées dans la direction longitudinale. Chaque languette est délimitée à ses deux extrémités par des fentes 17 réalisées par poinçonnage en travers de l'épaisseur du dos, orientées dans la direction longitudinale, qui permettent d'enfoncer la languette par emboutissage en direction de la semelle 4, selon un profil en arc comme vu sur la figure 5. La longueur des languettes 16 correspond à l'intervalle entre les deux nervures 5, de sorte que les deux extrémités de chaque languette peuvent venir sensiblement en appui sur les flancs internes des nervures, permettant un guidage longitudinal du support 8 par rapport à la joue 3.In each of the two regions of the back 8 adjacent to the two parts of the flange 11 are formed several stamped tongues 16, elongated in the lateral direction of the back and mutually aligned in the longitudinal direction. Each tongue is delimited at its two ends by slots 17 produced by punching across the thickness of the back, oriented in the longitudinal direction, which allow to press the tongue by stamping in the direction of the sole 4, according to an arcuate profile as seen in FIG. 5. The length of the tongues 16 corresponds to the interval between the two ribs 5, so that the two ends of each tongue may come to bear substantially on the internal sides of the ribs, allowing longitudinal guidance of the support 8 relative to the cheek 3.

Les bords libres des flasques 10 et 11 sont crénelés de façon à former des dents 18 qui, lorsque le support est convenablement positionné par rapport au faisceau de tubes et à la semelle 3, sont recourbées sous les bords 6 de la joue, chacune en direction de l'autre flasque, en pénétrant dans les tranches 7 de l'intercalaire qu'elles déforment. Ainsi la coopération des languettes 16 avec les nervures 5 immobilise le support 8 par rapport au bloc brasé dans la direction latérale, et le rabattement des dents 18 complète cette immobilisation dans la direction longitudinale et dans la direction d'alignement des tubes. Comme le montre la figure 7, les dents 18 rabattues peuvent venir en contact direct avec les bords 6 de la joue pour emprisonner celle-ci entre les dents et le dos 9, la déformation des tranches 7 assurant en outre l'immobilisation dans la direction longitudinale.The free edges of the flanges 10 and 11 are crenellated so as to form teeth 18 which, when the support is properly positioned with respect to the bundle of tubes and the sole 3, are bent under the edges 6 of the cheek, each in the direction on the other flange, by entering the sections 7 of the interlayer which they deform. Thus the cooperation of the tongues 16 with the ribs 5 immobilizes the support 8 relative to the block brazed in the lateral direction, and the folding of the teeth 18 completes this immobilization in the longitudinal direction and in the direction of alignment of the tubes. As shown in Figure 7, the folded teeth 18 can come into direct contact with the edges 6 of the cheek to trap it between the teeth and the back 9, the deformation of the edges 7 further ensuring immobilization in the direction longitudinal.

Un composant tel qu'une buse pour la canalisation d'un flux d'air peut être fixé sur le support 8 au moyen d'une vis se vissant dans le collet taraudé 15. En fonction des dimensions et du poids du composant, deux supports tels que 8 ou plus peuvent être disposés sur la joue 3. Bien entendu, des supports analogues peuvent être également montés sur une autre joue placée à l'extrémité inférieure du faisceau.A component such as a nozzle for channeling an air flow can be fixed on the support 8 by means of a screw screwed into the threaded collar 15. Depending on the dimensions and weight of the component, two supports such as 8 or more can be arranged on the cheek 3. Of course, similar supports can also be mounted on another cheek placed at the lower end of the beam.

Le support selon l'invention est facile et peu coûteux à réaliser et à mettre en place. Il peut être disposé à l'endroit voulu le long de la joue, sans modification de celle-ci. De plus, il est mis en place après le brasage du radiateur, de sorte que l'équipement de brasage n'a pas non plus à être modifié pour tenir compte de sa présence.The support according to the invention is easy and inexpensive to produce and install. It can be placed at the desired location along the cheek, without modification thereof. In addition, it is put in place after brazing the radiator, so that the brazing equipment also does not have to be modified to take account of its presence.
