Abstract

Heat-exchanger for vehicles and similar applications in which the circulation tubes are hairpin-shaped and emerge in a collector plate 3 covered by a water box 4 which is immobilised by bent-back tabs 5, characterised by a complementary collector plate 11 slipped onto the tubes 1 and placed near the bend 2 formed by these tubes, the said complementary plate 11 supporting at least one false box 12 fitted with centring 15 and/or fastening 14 members.

Description

La présente invention concerne les échangeurs de chaleur du genre de ceux qui sont utilisés pour le refroidissement du moteur de véhicules automobiles ou pour le chauffage de l'habitacle de ceux-ci. The present invention relates to heat exchangers of the kind used for cooling the engine of motor vehicles or for heating the passenger compartment thereof.

L'invention concerne, de manière plus particulière, ceux de ces échangeurs qui comportent des-- tubes en Epin- gle débouchant dans une même plaque collectrice divisée en plusieurs compartiments. The invention relates, more particularly, to those of these exchangers which comprise pinned tubes opening into the same collector plate divided into several compartments.

Ces échangeurs sont difficiles à fixer à la structure porteuse du véhicule car les tubes ont tendance à vibrer. These exchangers are difficult to fix to the supporting structure of the vehicle because the tubes tend to vibrate.

Pour remédier à cela, il a été proposé de disposer des noyaux entre les ailettes dissipatrices et les coudes formés par les tubes puis de relier ces noyaux à la structure porteuse du véhicule. To remedy this, it has been proposed to have cores between the dissipating fins and the elbows formed by the tubes and then to connect these cores to the supporting structure of the vehicle.

La disposition ci-dessus théoriquement satisfaisante présente des inconvénients. En particulier, elle rend difficile, voire impossible, l'automatisation de la fabrication. The above theoretically satisfactory arrangement has drawbacks. In particular, it makes automation of manufacturing difficult, if not impossible.

La présente invention crée un nouvel échangeur du type ci-dessus qui permet une fabrication automatisée et qui permet, en outre, d'utiliser un même faisceau échangeur pour correspondre à des structures de support différentes du véhicule. The present invention creates a new exchanger of the above type which allows automated manufacturing and which also makes it possible to use the same exchanger bundle to correspond to different support structures of the vehicle.

Conformément à l'invention, l'échangeur de chaleur pour véhicules et applications analogues dans lequel les tubes de circulation sont conformés en épingle et débouchent dans une plaque collectrice recouverte par une botte à eau immobilisée par des pattes repliées est caractérisé par une plaque collectrice complémentaire enfilée sur les tubes et disposée à proximité du coude que forment ces tubes, ladite plaque complémentaire supportant au moins une fausse botte munie d'organes de centrage et/ou de fixation. According to the invention, the heat exchanger for vehicles and similar applications in which the circulation tubes are shaped as a pin and open into a collecting plate covered by a water boot immobilized by folded legs is characterized by an additional collecting plate threaded on the tubes and arranged near the elbow formed by these tubes, said additional plate supporting at least one false boot provided with centering and / or fixing members.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.  Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forte de réalisation de ;'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé. A strong achievement of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

La fig. 1 est une vue de face d'un échangeur mettant en oeuvre l'invention. Fig. 1 is a front view of an exchanger implementing the invention.

La fig. 2 est une élévation latérale correspondant à la fig. 7,
L'échangeur illustré au dessin comporte des tubes 1 dits en épingle, c'est-à-dire des tubes qui sont cintrés pour former un coude 2 et deux brins parallèles la, lb
De manière bien connue, les extrémités libres des tubes sont engagées dans une plaque collectrice 3 qui est recouverte par une boite à eau 4 maintenue en place par des pattes repliées 5.Fig. 2 is a side elevation corresponding to FIG. 7,
The exchanger illustrated in the drawing comprises tubes 1 said to be hairpin, that is to say tubes which are bent to form an elbow 2 and two parallel strands la, lb
As is well known, the free ends of the tubes are engaged in a collecting plate 3 which is covered by a water box 4 held in place by folded tabs 5.

Dans ces types bien connus d'échangeurs, la boîte à eau 4 forme des tubulures de raccordement 6, 7 et également des organes de centrage 8 et de fixation tels que 9. In these well known types of exchangers, the water box 4 forms connecting pipes 6, 7 and also centering and fixing members 8 such as 9.

Les organes de fixation peuvent être différents suivant que l'échangeur est destiné à être monté sur un type de véhicule ou un autre. Ils peuvent, par exemple, prendre soit la forme de ceux illustrés en trait plein, soit la forme de ceux illustrés en traits mixtes et désignés par 10. The fixing members may be different depending on whether the exchanger is intended to be mounted on one type of vehicle or another. They can, for example, take either the form of those illustrated in solid lines, or the form of those illustrated in dashed lines and designated by 10.

Selon l'invention, une plaque collectrice complémentaire 11 est mise en place sur les tubes 1 pour être disposée à proximité des coudes 2 de ceux-ci;
La plaque collectrice complémentaire 11 est analogue, voire identique, à la plaque collectrice 3, et ses pattes 5 sont tournées vers les coudes 2 des tubes.According to the invention, a complementary collector plate 11 is placed on the tubes 1 to be arranged near the elbows 2 thereof;
The complementary collector plate 11 is analogous, even identical, to the collector plate 3, and its legs 5 are turned towards the elbows 2 of the tubes.

La plaque collectrice complémentaire 11 est destinée à supporter une ou des fausses boItes telles que 12 et 13 qui comportent des organes de fixation 14 et de centrage ou des organes ayant d'autres fonctions. The additional collector plate 11 is intended to support one or more false boxes such as 12 and 13 which comprise fixing members 14 and centering or members having other functions.

Comme cela est-représenté en trait plein et en trc.=s mixtes en ce qui concerne les organes 14a, la plaque collectrice complémentaire 11 permet un montage de la ou des fausses bol tes à différents endroits qui dépendent uniquement des structures de fixation que comporte le véhicule qui doit recevoir l'échangeur de chaleur. As shown in solid line and in trc. = S mixed with respect to the members 14a, the additional collector plate 11 allows mounting of the false bowl (s) at different locations which depend solely on the fixing structures that comprise the vehicle that is to receive the heat exchanger.

La ou les fausses boites 12 peuvent, suivant les besoins, s'étendre sur tout ou partie seulement de la plaque collectrice complémentaire 11 ou, comme le montre le dessin, la plaque collectrice complémentaire peut être munie de plusieurs fausses boites 12, t3. The false box or boxes 12 can, as required, extend over all or only part of the complementary collecting plate 11 or, as shown in the drawing, the complementary collecting plate can be provided with several false boxes 12, t3.

Les fausses boites 12, 13 n'étant pas en contact avec le liquide en circulation dans les tubes 1, aucun moyen d'étanchéité n'est à prévoir entre elles et la plaque collectrice complémentaire. De plus, les fausses boites 12, 13 peuvent être fabriquées en des matières. de qualité différente de celle de la bol te 4 et en particulier en des matières bon marché et faciles à former, notamment à mouler. The false boxes 12, 13 not being in contact with the liquid circulating in the tubes 1, no sealing means is to be provided between them and the additional collecting plate. In addition, the false boxes 12, 13 can be made of materials. of a quality different from that of the bowl te 4 and in particular in inexpensive materials which are easy to form, in particular to mold.

La fixation des fausses boites 12, 13 est réalisée de manière analogue à celle de la boite à eau 4 par les pattes 5 qui sont repliées après mise en place. En outre, il est avantageux que les fausses boites présentent des nervures 12a correspondant aux espaces séparant les pattes 5 ce qui évite tout glissement lorsqu'une fausse boite s'étend sur une partie seulement de la longueur de la plaque collectrice complémentaire 11. The fixing of the false boxes 12, 13 is carried out in a similar manner to that of the water box 4 by the tabs 5 which are folded after installation. In addition, it is advantageous for the false boxes to have ribs 12a corresponding to the spaces separating the tabs 5, which prevents any slipping when a false box extends over only part of the length of the complementary collector plate 11.

Ii est avantageux, bien que non nécessaire, pour permettre une fabrication automatisée que la plaque collectrice 3 de même que la plaque collectrice complémentaire 11 présentent des lumières 15 pour l'introduction de bossettes 16 assurant le maintien provisoire de la boite à eau 4 d'une part, et de la ou des fausses boites 12, 13, d'autre part, avant que les pattes 5 soient repliées. It is advantageous, although not necessary, to allow automated manufacture that the collector plate 3 as well as the complementary collector plate 11 have slots 15 for the introduction of dimples 16 ensuring the provisional maintenance of the water box 4 of on the one hand, and one or more false boxes 12, 13, on the other hand, before the tabs 5 are folded.

Il est avantageux que les brins la, lb des tubes 1 soient gonflés à la fois dans la plaque collectrice 3 et dans la plaque collectrice complémentaire 11 pour immobiliser cette dernière par rapport aux tubes en même temps que l'étanchéité est assurée entre les tubes et la plaque collectrice 3; le gonflage a lieu également après mise en place des ailettes dissipatrices 17. It is advantageous for the strands 1a, 1b of the tubes 1 to be inflated both in the collecting plate 3 and in the additional collecting plate 11 to immobilize the latter relative to the tubes at the same time as the seal is ensured between the tubes and the collecting plate 3; inflation also takes place after fitting of the dissipating fins 17.

L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.  The invention is not limited to the embodiment shown and described in detail, because various modifications can be made without departing from its scope.
