Description

La présente invention est relative à un échan­geur de chaleur du type dit à faisceau tubulaire c'est-à-dire dont les tubes sont engagés dans des dissi­pateurs et dans au moins une plaque collectrice.The present invention relates to a heat exchanger of the type known as a tube bundle, that is to say the tubes of which are engaged in dissipators and in at least one collecting plate.

Plus particulièrement encore, l'invention concerne ceux de ces échangeurs dont les jeux de tubes débouchent dans deux chambres distinctes d'une boîte à eau reliée à une plaque collectrice qui est retenue de façon étanche sur un joint formé à partir d'une nappe en matière élastique délimitant supplémentairement des douilles qui assurent l'étanchéité entre la plaque collectrice et l'extrémité des tubes.More particularly still, the invention relates to those of these exchangers whose sets of tubes open into two separate chambers of a water box connected to a collector plate which is retained in leaktight manner on a seal formed from a sheet of elastic material additionally delimiting sockets which seal between the collector plate and the end of the tubes.

Il a été constaté, que dans certaines condi­tions d'utilisation, la perte de charge du fluide en circulation produite atteint une mesure excessive, ce qui est dommageable car, au-delà d'un certain seuil, le différentiel de pression qui existe entre les deux chambres de la boîte à eau peut provoquer des déforma­tions de la cloison interne dont est munie cette boîte à eau ; il peut ainsi en résulter un endommagement de la nappe en matière élastique.It has been observed that, under certain conditions of use, the pressure drop of the circulating fluid produced reaches an excessive measure, which is harmful because, beyond a certain threshold, the pressure differential which exists between the two chambers of the water box can cause deformations of the internal partition with which this water box is provided; it can thus result in damage to the ply of elastic material.

Outre ce qui précède, une trop grande perte de charge du fluide de circulation peut engendrer des phénomènes de cavitation au niveau de la pompe de mise en circulation du fluide.In addition to the above, too great a pressure drop in the circulation fluid can cause cavitation phenomena at the level of the fluid circulation pump.

L'invention crée des moyens par lesquels la perte de charge est limitée à un seuil préétabli de sorte que les inconvénients mentionnés dans ce qui précède sont éliminés.The invention creates means by which the pressure drop is limited to a predetermined threshold so that the drawbacks mentioned in the foregoing are eliminated.

Conformément à l'invention, l'échangeur de chaleur à faisceau tubulaire dont des jeux de tubes sont reliés à au moins une plaque collectrice dont la face tournée vers une boîte à eau est recouverte par une nappe en matière élastique formant des douilles pour les extrémités des tubes et un joint pour la boîte à eau est caractérisé en ce que, dans l'application à un échangeur à plusieurs passes, la boîte à eau est munie au moins d'une cloison délimitant des chambres et en ce que la cloison présente au moins une lumière normalement fermée par un clapet issu de la nappe.In accordance with the invention, the tube bundle heat exchanger, of which sets of tubes are connected to at least one collecting plate, the face of which faces a water box is covered by a sheet of elastic material forming sockets for the ends. tubes and a seal for the water box is characterized in that, in the application to a multiple pass exchanger, the water box is provided with at least one partition delimiting chambers and in that the partition has at least one lumen normally closed by a valve coming from the tablecloth.

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 forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé.

  • La figure 1 est une coupe-élévation schématique d'un échangeur de chaleur à faisceau tubulaire auquel s'applique l'invention.
  • La figure 2 est une coupe-élévation partielle très agrandie d'une partie apparaissant à la figure 1.
  • La figure 3 est une coupe vue sensiblement suivant la ligne III-III de la figure 2.
  • La figure 4 est une coupe partielle vue suivant la ligne IV-IV de la figure 3.
An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.
  • Figure 1 is a schematic sectional elevation of a tube bundle heat exchanger to which the invention applies.
  • FIG. 2 is a very enlarged partial sectional elevation of a part appearing in FIG. 1.
  • FIG. 3 is a section seen substantially along line III-III of FIG. 2.
  • FIG. 4 is a partial section seen on line IV-IV of FIG. 3.

La figure 1 illustre de façon schématique un échangeur de chaleur, par exemple un radiateur de refroidissement du type à deux passes méthodiques. Par conséquent, le radiateur comporte des jeux de tubes 1, 1ª qui débouchent dans des boîtes à eau 2, 3 montées dans des plaques collectrices 4, 5 qui sont recouvertes, sur toute leur surface tournée vers l'intérieur des boîtes à eau, par des nappes 6, 7 en matière souple et élastique. Les nappes 6, 7 délimitent des douilles 8 destinées à assurer l'étanchéité avec la paroi externe de chaque extrémité des jeux de tubes 1, 1ª.FIG. 1 schematically illustrates a heat exchanger, for example a cooling radiator of the type with two methodical passes. Consequently, the radiator comprises sets of tubes 1, 1ª which open into water boxes 2, 3 mounted in collecting plates 4, 5 which are covered, over their entire surface facing the inside of the water boxes, by plies 6, 7 made of flexible and elastic material. The plies 6, 7 delimit sockets 8 intended to seal with the external wall of each end of the sets of tubes 1, 1ª.

Les nappes 6, 7 forment également un joint périphérique 9 destiné à assurer l'étanchéité avec le bord périphérique 2ª, 3ª de la boîte à eau correspondante.The layers 6, 7 also form a peripheral seal 9 intended to seal with the peripheral edge 2ª, 3ª of the corresponding water box.

Dans le cas considéré d'un échangeur de chaleur à deux passes méthodiques, l'une des boîtes à eau, par exemple la boîte à eau 2, est séparée en deux compartiments 10, 11 par une cloison 12 s'étendant longitudinalement dans l'exemple représenté.In the case under consideration of a heat exchanger with two methodical passes, one of the water boxes, for example the water box 2, is separated into two compartments 10, 11 by a partition 12 extending longitudinally in the example shown.

De cette manière, le fluide de circulation devant parcourir les tubes de l'échangeur de chaleur circule comme illustré par les flèches, c'est-à-dire, par exemple, à partir du compartiment 10 en passant par les tubes 1 puis, à partir de la boîte à eau 3, le fluide est ramené par les tubes 1ª dans le compartiment 11 pour être réutilisé.In this way, the circulation fluid which must pass through the tubes of the heat exchanger circulates as illustrated by the arrows, that is to say, for example, from the compartment 10 passing through the tubes 1 then, at from the water box 3, the fluid is brought back by the tubes 1ª into the compartment 11 to be reused.

Selon l'invention, on prévoit dans la cloison 12 au moins une lumière 13 et la nappe 6 forme, en regard de cette lumière, un clapet 14. De préférence, le clapet 14 est renforcé par une, ou des nervures 15, qui s'étend sur la face opposée à celle tournée vers la lumière 13 entre les douilles 8.According to the invention, at least one opening 13 is provided in the partition 12 and the ply 6 forms, opposite this opening, a valve 14. Preferably, the valve 14 is reinforced by one or more ribs 15 which 'extends on the face opposite to that facing the light 13 between the sockets 8.

Pour que le clapet 14 assure une bonne étanchéité avec la cloison 12, il présente, à sa périphérie, un bourrelet ou une lèvre mince 16.So that the valve 14 provides a good seal with the partition 12, it has, at its periphery, a bead or a thin lip 16.

Le clapet 14 fait partie intégrante de la nappe 6 c'est-à-dire qu'il vient en moulage avec celle-ci en même temps que les douilles 8 et que le joint périphérique 9.The valve 14 is an integral part of the ply 6, that is to say that it comes into molding with the latter at the same time as the sockets 8 and the peripheral seal 9.

Lorsque la plaque collectrice 4 présente, comme illustré au dessin, une rainure longitudinale 17 dans laquelle est retenu le pied de la cloison 12, il est avantageux que la nappe 6 ne soit pas moulée pour épouser initialement la rainure 17 et, par ailleurs, il est avantageux que le clapet 14 soit moulé pour qu'il s'étende légèrement en oblique tant que la boîte à eau n'est pas mise en place sur la plaque collectrice.When the collector plate 4 has, as illustrated in the drawing, a longitudinal groove 17 in which the foot of the partition 12 is retained, it is advantageous that the ply 6 is not molded to initially match the groove 17 and, moreover, it it is advantageous for the valve 14 to be molded so that it extends slightly obliquely as long as the water box is not placed on the collecting plate.

Comme l'illustre en particulier la figure 4, lorsque la boîte à eau 2 est mise en place, sa cloison médiane 12 est déplacée suivant la flèche f₁. Il s'ensuit que la partie de la nappe sur laquelle appuie la cloison est progressivement déformée en arc de cercle pour venir occuper la position illustrée à la fig. 2. Cela a pour effet de faire basculer le clapet 14 et à amener celui-ci en appui contre la face de la cloison 12 en assurant ainsi une étanchéité appropriée entre les compartiments 10 et 11 de la boîte à eau.As illustrated in particular in FIG. 4, when the water box 2 is put in place, its partition median 12 is moved along the arrow f₁. It follows that the part of the sheet on which the partition rests is gradually deformed in an arc to come to occupy the position illustrated in FIG. 2. This has the effect of tilting the valve 14 and bringing it in abutment against the face of the partition 12 thereby ensuring an appropriate seal between the compartments 10 and 11 of the water box.

En fonctionnement normal, la circulation de l'échangeur de chaleur décrit s'effectue de la manière indiquée dans ce qui précède c'est-à-dire que le fluide circule depuis le compartiment 10 par les jeux de tubes 1, 1ª vers le compartiment 11 d'où ce fluide est dirigé vers un lieu d'utilisation.In normal operation, the circulation of the heat exchanger described takes place in the manner indicated in the above, that is to say that the fluid circulates from the compartment 10 by the sets of tubes 1, 1ª towards the compartment 11 where this fluid is directed to a place of use.

Dans certaines conditions de fonctionnement de l'installation qui comporte l'échangeur de chaleur décrit, il peut arriver que la vitesse de circulation du fluide à l'intérieur de l'échangeur soit telle qu'elle engendre des pertes de charge inadmissibles ; cela peut être le cas, par exemple, pour un radiateur de refroi­dissement du liquide circulant dans un moteur thermique dont la pompe à eau serait entraînée à vitesse excessive.Under certain operating conditions of the installation which includes the heat exchanger described, it may happen that the speed of circulation of the fluid inside the exchanger is such that it generates unacceptable pressure drops; this may be the case, for example, for a radiator for cooling the liquid circulating in a heat engine whose water pump would be driven at excessive speed.

Ainsi que cela ressort de la description qui précède, si la perte de charge dépasse un seuil déterminé dans les tubes 1, 1ª, il en résulte un différentiel de pression entre les compartiments 10, 11 de la boîte à eau 2. Ce différentiel de pression fait que le clapet 14 est ouvert par basculement et, par conséquent, du fluide peut s'écouler directement de la chambre 10 vers la cham­bre 11.As appears from the above description, if the pressure drop exceeds a determined threshold in the tubes 1, 1ª, this results in a pressure differential between the compartments 10, 11 of the water box 2. This pressure differential the fact that the valve 14 is opened by tilting and, consequently, fluid can flow directly from the chamber 10 towards the chamber 11.

Dès que ce différentiel de pression est suffi­samment réduit, l'élasticité du clapet 14 fait que celui-ci ferme à nouveau la lumière 13 à laquelle il correspond.As soon as this pressure differential is sufficiently reduced, the elasticity of the valve 14 means that it again closes the lumen 13 to which it corresponds.

Lorsque la nappe 6 qui forme le ou les clapets 14 n'est pas déformée comme illustré au dessin, ledit clapet 14 est avantageusement moulé de façon qu'il soit légèrement incliné mais dans le sens opposé à celui représenté à la fig. 4 afin qu'il soit normalement appliqué contre la cloison 12 lors de la mise en place de la boîte à eau 2.When the ply 6 which forms the valve or valves 14 is not deformed as illustrated in the drawing, said valve 14 is advantageously molded so that it is slightly inclined but in the opposite direction to that shown in FIG. 4 so that it is normally applied against the partition 12 when the water box 2 is put in place.

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. En particulier, elle peut être mise en oeuvre de même manière dans un échangeur de chaleur ne comportant pas la boîte à eau 3 illustrée à la fig. 1. Les jeux de tubes 1, 1ª sont alors constitués par des tubes coudés en épingle.The invention is not limited to the embodiment, shown and described in detail, because various modifications can be made without departing from its scope. In particular, it can be implemented in the same way in a heat exchanger not comprising the water box 3 illustrated in FIG. 1. The sets of tubes 1, 1ª are then constituted by bent hairpin tubes.
