Abstract

1. Heat exchanger with tubes locked to the tube end plate comprising fins (2) engaged on the tubes (1) which are themselves engaged into resilient material collars (5) placed into the tube passages of a tube end plate (3), characterized by stop members (7) having at least one hole (8) of a diameter smaller than outer diameter of the tubes, said stop members being forcibly engaged on the end protruding in the tube end plate of at least some of the tubes to which it is connected.

Description

La présente invention concerne un échangeur de chaleur du type à tubes et ailettes dont les tubes sont engagés dans des plaques collectrices auxquelles ils sont reliés par des co- lets ou douilles en matière élastique.The present invention relates to a heat exchanger of the tube and fin type, the tubes of which are engaged in collecting plates to which they are connected by means of elastic bands or sleeves.

Les échangeurs réalisés de cette façon donnent satisfaction mais ils nécessitent souvent de prévoir des joues latérales reliant les plaques collectricesou les boites à eau afin d'empêcher que des sollicitations mécaniques provoquent un déplacenent graduel des ensembles plaques collectrices-boîtes à eau par rapport aux tubes. Par ailleurs, il est souhaitable, notamment pour réduire le prix de revient des appareils, de ne pas utiliser de joues latérales.The exchangers produced in this way are satisfactory but they often require the provision of lateral cheeks connecting the manifold plates or the water boxes in order to prevent mechanical stresses causing a gradual displacement of the manifold plate-water box assemblies relative to the tubes. Furthermore, it is desirable, in particular to reduce the cost price of the devices, not to use side cheeks.

Pour résoudre ce problème, il a déjà été proposé d'évaser la partie des tubes qui traverse la plaque collectrice et qui s'étend au-delà de celle-ci. L'évasement ou gonflage de l'extrémité des tubes constitue une opération qui est relativement longue et donc coûteuse. De plus,cet évasement est incompatible avec l'emploi de plaques collectrices déjà assemblées aux boîtes.To solve this problem, it has already been proposed to flare the part of the tubes which crosses the collector plate and which extends beyond the latter. The flaring or inflation of the end of the tubes constitutes an operation which is relatively long and therefore expensive. In addition, this flare is incompatible with the use of manifold plates already assembled to the boxes.

L'invention résout le problème exposé en créant un nouvel échangeur de chaleur à tubes verrouillés au collecteur.The invention solves the problem exposed by creating a new heat exchanger with tubes locked to the collector.

Conformément à l'invention, l'échangeur de chaleur à tubes verrouillés au collecteur comportant des ailettes enfilées sur les tubes qui sont eux-mêmes engagés dans des collets en matière élastique disposés dans les passages de tube d'une plaque collectrice, est caractérisé par des éléments d'arrêt présentant au moins un trou de diamètre plus petit que le diamètre extérieur des tubes, ledit élément d'arrêt étant enfilé à force sur l'extrémité saillant dans la plaque collectrice d'au moins certains des tubes auxquels elle est reliée.According to the invention, the heat exchanger with tubes locked to the manifold comprising fins threaded onto the tubes which are themselves engaged in collars of elastic material arranged in the tube passages of a manifold plate, is characterized by stop elements having at least one hole with a diameter smaller than the outside diameter of the tubes, said stop element being force-fitted on the projecting end in the collec plate trice at least some of the tubes to which it is connected.

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.

Au dessin, 1 désigne des tubes de circulation de section ronde d'un échangeur de chaleur sur lesquels sont enfilées des ailettes de refroidissement 2. De préférence, les ailettes 2 sont repliées sur leurs petits cotés comme montré en 2a afin que les ailettes successives soient en contact les unes avec les autres pour délimiter des guides latéraux pour l'air devant traverser l'échangeur.In the drawing, 1 designates circulation tubes of round section of a heat exchanger on which are threaded cooling fins 2. Preferably, the fins 2 are folded over their short sides as shown in 2a so that the successive fins are in contact with each other to delimit lateral guides for the air which must pass through the exchanger.

De façon connue en soi, l'échangeur comporte des plaques collectrices 3 qui,dans le mode de réalisation des fig. 1 à 8,sont en matière synthétique. Les plaques collectrices 3 délimitent des passages de tubes 4 dans lesquels sont engagés des collets 5 déformables, saillant d'une feuille ou plaque élastique 6,par exemple en caoutchouc. Les tubes 1 sont engagés à force dans les collets 5 pour faire saillie au-dessus de ceux-ci.In a manner known per se, the exchanger comprises manifold plates 3 which, in the embodiment of FIGS. 1 to 8, are made of synthetic material. The collector plates 3 delimit passages of tubes 4 in which are engaged deformable collars 5, projecting from a sheet or elastic plate 6, for example made of rubber. The tubes 1 are forcibly engaged in the collars 5 to protrude above them.

Des éléments d'arrêt 7 sont ensuite mis en place sur certaines au moins des extrémités saillantes des tubes 1. Les éléments d'arrêt sont, par exemple, placés sur les deux derniers rangs de tubes comme illustré à la fig. 1. Ils pourraient évidemment être placés sur tous les tubes mais cela n'est généralement pas nécessaire. Les éléments d'arrêt illustrés aux fig. 1et 4 sont constitués par des rondelles, par exemple de forme circulaireiqui présentent en leur centre un trou 8.Stop elements 7 are then placed on at least some of the projecting ends of the tubes 1. The stop elements are, for example, placed on the last two rows of tubes as illustrated in FIG. 1. They could obviously be placed on all the tubes but this is generally not necessary. The stop elements illustrated in fig. 1 and 4 consist of washers, for example of circular shape, which have a hole 8 in their center.

A la fig. 3, des découpes radiales 9 partent du trou 8 et s'étendent sur une partie de la rondelle.In fig. 3, radial cutouts 9 start from the hole 8 and extend over part of the washer.

A la fig. 4, des encoches 10 sont prévues à partir du trou 8.In fig. 4, notches 10 are provided from the hole 8.

Dans les deux cas les rondelles délimitent ainsi des pattes 11 à bords vifs.In both cases, the washers thus define tabs 11 with sharp edges.

Les éléments d'arrêt peuvent être plans,mais de préférence ils présentent une forme hémisphérique dont la convexité est tournée vers le haut. Le diamètre du trou 8 est plus petit que le diamètre extérieur des tubes 1.The stop elements may be planar, but preferably they have a hemispherical shape whose convexity is turned upwards. The diameter of the hole 8 is smaller than the outside diameter of the tubes 1.

Les éléments d'arrêt sont enfoncés à force sur les extrémités des tubes 1 pour serrer fortement la paroi de ceux-ci en même temps que leur dessous déforme la partie saillante 5a (fig. 2) des collets 5.The stop elements are force-fitted onto the ends of the tubes 1 in order to tighten the wall of the latter strongly at the same time as their underside deforms the projecting part 5a (FIG. 2) of the collars 5.

La fig. 2 montre aussi que le bord périphérique 7a des éléments d'arrêt plans appuie avantageusement sur le dessus de la plaque collectrice 3. Les bords vifs 11 des éléments d'arrêt ont tendance à s'encastrer dans la paroi des tubes l,principalement si ces tubes tendaient à être déplacés vers le bas par rapport à la plaque collectrice 3. On est assuré de cette façon que les tubes sont parfaitement immobilisés par rapport à la plaque collectrice.Fig. 2 also shows that the peripheral edge 7a of the planar stop elements advantageously presses on the top of the collector plate 3. The sharp edges 11 of the stop elements tend to become embedded in the wall of the tubes l, mainly if these tubes tended to be moved down relative to the collector plate 3. It is ensured in this way that the tubes are perfectly immobilized relative to the collector plate.

Dans le mode de réalisation décrit, lorsque les éléments d'arrêt 7 ont été mis en place, on monte sur la plaque collectrice 3 une boite à eau 12 et le bord 12a de celle-ci est fixé, par exemple soudé par vibrations,sur le bord périphérique correspondant à la plaque collectrice. Dans certains cas, pour augmenter les cadences de fabrication, il est avantageux de réunir l'ensemble plaques collectrices 3-boîte à eau 12 avant d'engager les tubes 1 dans les collets 5 saillant de la feuille en matière élastique 6. Dans ce cas et comme l'illustrent les fig. 5 à 8, il est avantageux de constituer les éléments d'arrêt sous la forme de plaquettes 71 ou 72 de la fig. 10 dans lesquelles sont -pratiqués les trous 8 et les découpes 9 ou les encoches 10 décrits dans ce qui précède.In the embodiment described, when the stop elements 7 have been put in place, a water box 12 is mounted on the collecting plate 3 and the edge 12a thereof is fixed, for example welded by vibration, to the peripheral edge corresponding to the collector plate. In certain cases, in order to increase the production rates, it is advantageous to assemble the assembly of collector plates 3-water box 12 before engaging the tubes 1 in the collars 5 projecting from the sheet of elastic material 6. In this case and as illustrated in figs. 5 to 8, it is advantageous to constitute the stop elements in the form of plates 7 1 or 7 2 of FIG. 10 in which the holes 8 and the cutouts are made pes 9 or the notches 10 described in the foregoing.

A la fig. 10 la plaquette 72 comporte des bords tombés 10In fig. 10 the plate 7 2 has fallen edges 10

On prévoit aussi avantageusement au moins un trou supplémentaire de centrage 13 correspondant à un pion 14 saillant de la plaque collectrice 3. Par ailleurs, on délimite une encoche ou rainure 15 dans une partie au moins du bord périphérique de la boîte à eau 12 pour recouvrir le bord de la plaquette 71, par exemple sur trois côtés comme illustré en 15a à la fig. 8 ou deux côtés comme montré à la fig. 11. De plus, on munit l'intérieur de la boîte à eau 12 de chandelles 17 correspondant aux pions 14.There is also advantageously provided at least one additional centering hole 13 corresponding to a pin 14 projecting from the collector plate 3. Furthermore, a notch or groove 15 is defined in at least part of the peripheral edge of the water box 12 to cover the edge of the plate 7 1 , for example on three sides as illustrated in 15a in fig. 8 or two sides as shown in fig. 11. In addition, the inside of the water box 12 is fitted with candles 17 corresponding to the pins 14.

A la fig. 11 les chandelles peuvent être omises.In fig. 11 candles may be omitted.

Lorsqu'on procède au soudage de la boîte à eau par vibrations, le bord de celle-ci est soudé au bord de la plaque collectrice et il en est de même de l'extrémité de la chandelle 17 qui est soudée au pion 14 comme l'illustre la fig. 7 . On voit par ce qui précède que la plaque constituant l'élément d'arrêt est alors encastrée entre la plaque collectrice et la boîte à eau réunies entre elles.When the water box is welded by vibration, the edge of the latter is welded to the edge of the collector plate and the same is true of the end of the jack 17 which is welded to the pin 14 like the 'illustrates fig. 7. It can be seen from the above that the plate constituting the stop element is then embedded between the collector plate and the water box joined together.

Le montage de l'échangeur peut alors être effectué en enfonçant à force les tubes 1 du faisceau échangeur préalablement préparé,c'est-à-dire muni des ailettes 2 dans les collets et les trous 8 de l'élément d'arrêt dont le mode d'action est ensuite exactement le même que celui décrit dans ce qui précède.The assembly of the exchanger can then be carried out by forcing the tubes 1 of the previously prepared exchanger bundle, that is to say fitted with fins 2 into the collars and the holes 8 of the stop element, the mode of action is then exactly the same as that described in the foregoing.

Les exemples ci-dessus illustrent la mise en oeuvre de l'invention dans le cas où la plaque collectrice est en matière synthétique. L'invention peut être mise en oeuvre également lorsque la plaque collectrice est métallique. Dans ce cas, les éléments d'arrêt figurés sous la forme de rondelles 7 sont mis en place sur les extrémités des tubes 1 exactement comme décrit dans ce qui précède.The above examples illustrate the implementation of the invention in the case where the collector plate is made of synthetic material. The invention can also be implemented when the collector plate is metallic. In that case, the stop elements shown in the form of washers 7 are placed on the ends of the tubes 1 exactly as described in the foregoing.

Il peut être avantageux, lorsque la plaque collectrice 31 est en métal, que la feuille 6 en matière souple élastique formant les collets 5 soit placée sur la face de ladite plaque collectrice qui est tournée vers la boîte à eau 12. C'est ce cas particulier qui est représenté à la fig. 9.It may be advantageous, when the collector plate 3 1 is made of metal, that the sheet 6 of flexible elastic material forming the collars 5 is placed on the face of the said collector plate which faces the water box 12. This is what particular case which is shown in fig. 9.

Dans cette réalisation, la boite à eau peut-être en matière synthétique ou en métal et avantageusement assemblée à la plaque collectrice par des moyens mécaniques,par exemple une pièce de sertissage 18.In this embodiment, the water box may be made of synthetic material or metal and advantageously assembled with the collecting plate by mechanical means, for example a crimping piece 18.

L'invention n'est pas limitée aux exemples de réalisation, représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the exemplary embodiments, shown and described in detail, since various modifications can be made thereto without departing from its scope.
