Description
L'invention concerne un échangeur de chaleur comprenant une rangée de tubes de circulation de fluide contenant chacun une plaque perturbatrice destinée à produire un écoulement turbulent du fluide, et au moins une boíte collectrice allongée dans la direction d'alignement des tubes et dans laquelle débouche une extrémité de chacun d'eux, ladite boíte collectrice étant formée d'un empilement de paires de coquilles dans lequel chaque coquille présente une paroi latérale annulaire raccordée d'une part à un rebord extérieur annulaire et d'autre part à un rebord intérieur annulaire défini par le fond de la coquille muni d'une ouverture axiale, ces deux rebords s'étendant sensiblement selon des plans radiaux, les coquilles d'une même paire étant mutuellement accolées et assemblées par leurs rebords extérieurs, et deux coquilles adjacentes appartenant à des paires différentes par leurs rebords intérieurs, en délimitant une chambre interne sur toute la longueur de l'empilement, les parois des deux coquilles d'une même paire étant aménagés de façon à définir une ouverture latérale dans laquelle s'insère l'extrémité d'un tube pour communiquer avec ladite chambre interne.The invention relates to a heat exchanger comprising a row of fluid circulation tubes each containing a disturbing plate intended to produce a flow turbulent fluid, and at least one manifold elongated in the direction of alignment of the tubes and in which opens one end of each of them, said box collector being formed of a stack of pairs of shells in which each shell has a wall annular lateral connected on the one hand to an external rim annular and secondly to an annular inner rim defined by the bottom of the shell provided with an opening axial, these two edges extending substantially in radial planes, the shells of the same pair being mutually joined and joined by their outer edges, and two adjacent shells belonging to different pairs by their interior edges, delimiting a room internal along the entire length of the stack, the walls of the two shells of the same pair being arranged so as to define a side opening into which fits the end of a tube to communicate with said chamber internal.
Un tel échangeur de chaleur est connu par FR-A-2-563 899. Dans cet échangeur de chaleur connu, les coquilles formant la boíte collectrice sont en contact exclusivement les unes avec les autres et avec les extrémités des tubes engagées dans les ouvertures latérales. On a pu constater une rigidité insuffisante de la boíte collectrice ainsi réalisée.Such a heat exchanger is known from FR-A-2-563 899. In this known heat exchanger, the shells forming the manifold are in contact exclusively with each the others and with the ends of the tubes engaged in the side openings. We could see an insufficient rigidity of the manifold thus produced.
Le but de l'invention est de remédier à cet inconvénient.The object of the invention is to remedy this drawback.
L'invention vise notamment un échangeur de chaleur du genre défini en introduction, et prévoit que la plaque perturbatrice fait saillie au-delà de l'extrémité dudit tube pour venir en contact avec les coquilles de ladite paire sur une fraction au moins de la périphérie de la chambre interne.The invention relates in particular to a heat exchanger of the kind defined in the introduction, and provides that the disruptive plate protrudes beyond the end of said tube to come into contact with the shells of said pair on a fraction at least of the periphery of the internal chamber.
La partie en saillie de la plaque perturbatrice offre des zones de contact supplémentaires pour les coquilles, améliorant ainsi la stabilité de forme de celles-ci et par conséquent la rigidité de la boíte, pour une épaisseur donnée des coquilles.The protruding part of the disturbing plate provides additional contact areas for the shells, enhancing thus the shape stability of these and therefore the rigidity of the box, for a given thickness of shells.
L'échangeur de chaleur selon l'invention est utilisable notamment pour le refroidissement de l'air de suralimentation d'un moteur thermique d'entraínement d'un véhicule, plus particulièrement d'un véhicule industriel. Bien entendu, deux boítes collectrices peuvent être prévues dans lesquelles pénètrent respectivement les deux extrémités de chaque tube, les plaques perturbatrices faisant saillie dans les mêmes conditions dans les deux boítes aux deux extrémités des tubes.The heat exchanger according to the invention can be used especially for cooling the charge air a heat engine for driving a vehicle, plus particularly of an industrial vehicle. Of course, two manifolds can be provided in which penetrate the two ends of each tube respectively, the disruptive plates protruding into the same conditions in the two boxes at the two ends of tubes.
Des caractéristiques optionnelles de l'invention, complémentaires ou alternatives, sont énoncées ci-après :
- Le rebord extérieur de l'une au moins des coquilles de la paire présente une région annulaire, adjacente à la paroi latérale, en retrait vers le plan du rebord intérieur, coopérant avec le rebord extérieur de l'autre coquille pour former un logement recevant la plaque perturbatrice.
- Les deux coquilles de la paire sont identiques, l'épaisseur dudit logement étant définie pour moitié par la région en retrait de chaque rebord extérieur.
- Ladite région annulaire en retrait se raccorde, du côté du passage du tube, à une région marginale du même rebord extérieur davantage encore en retrait, les régions marginales en retrait des deux coquilles de la paire définissant un logement pour l'extrémité du tube.
- La région de la plaque perturbatrice en saillie par rapport au tube présente une ouverture alignée avec les ouvertures axiales des coquilles de façon à ne pas gêner la circulation du fluide dans ladite chambre.
- Le rebord extérieur de chaque coquille se raccorde, sur une partie au moins de sa périphérie, à une jupe s'étendant axialement vers le plan du rebord intérieur de la même coquille.
- Le rebord extérieur et la paroi latérale des coquilles présentent respectivement un contour sensiblement rectangulaire et une section circulaire.
- The outer rim of at least one of the shells of the pair has an annular region, adjacent to the side wall, recessed towards the plane of the inner rim, cooperating with the outer rim of the other shell to form a housing receiving the disruptive plate.
- The two shells of the pair are identical, the thickness of said housing being defined for half by the region set back from each outer rim.
- Said annular recessed region is connected, on the side of the passage of the tube, to a marginal region of the same outer rim which is further recessed, the marginal regions recessed from the two shells of the pair defining a housing for the end of the tube.
- The region of the disturbing plate projecting from the tube has an opening aligned with the axial openings of the shells so as not to hinder the circulation of the fluid in said chamber.
- The outer rim of each shell is connected, over at least part of its periphery, to a skirt extending axially towards the plane of the inner rim of the same shell.
- The outer rim and the side wall of the shells respectively have a substantially rectangular outline and a circular section.
Les caractéristiques et avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés, sur lesquels :
- les figures 1 et 2 sont des vues partielles en coupe d'un échangeur de chaleur conforme à l'invention, selon des plans mutuellement perpendiculaires passant par l'axe de la boíte collectrice; et
- la figure 3 est une vue partielle prise selon la direction axiale de la boíte collectrice.
- Figures 1 and 2 are partial sectional views of a heat exchanger according to the invention, according to mutually perpendicular planes passing through the axis of the manifold; and
- Figure 3 is a partial view taken in the axial direction of the manifold.
Sur la figure 1 sont représentées deux paires 1 et 2 de
pièces métalliques en forme de cuvettes ou de coquilles,
formées à partir de tôle emboutie et appartenant à un
empilement constituant une boíte collectrice non représentée
dans son ensemble. Les deux coquilles 3 et 4 composant
chacune des paires 1 et 2 sont identiques. Chacune comprend
un fond 5 disposé selon un plan radial, c'est-à-dire perpendiculaire
à l'axe longitudinal 6 de la boíte collectrice, se
raccordant à une paroi latérale annulaire 7 de révolution
autour de l'axe 6. Le fond 5 est percé d'une ouverture
centrale 8, également de révolution autour de l'axe 6,
définissant ainsi autour de celle-ci un rebord intérieur
annulaire 9. A l'opposé du fond 5 dans la direction axiale,
la paroi latérale 7 se raccorde à un rebord annulaire 10 qui
s'étend radialement vers l'extérieur. Comme le montre la
figure 3, ce rebord extérieur 10 présente un contour extérieur
rectangulaire à angles arrondis, et se raccorde à son
tour à une jupe annulaire périphérique 11 tournée axialement
vers le fond 5.In Figure 1 are represented two pairs 1 and 2 of
metal parts in the form of bowls or shells,
formed from pressed sheet metal and belonging to a
stack constituting a manifold not shown
in general. The two
Le rebord extérieur 10 présente trois régions situées
sensiblement dans trois plans radiaux. Une première région
annulaire 12 de contour extérieur rectangulaire entoure
directement la paroi latérale 7. La portion 12 est bordée sur
trois de ses côtés par une seconde portion 13 qui forme une
bande recourbée en U s'étendant jusqu'à la périphérie du
rebord 10 pour se raccorder à la jupe 11 le long de trois
côtés du contour rectangulaire de la coquille. Enfin, une
troisième région 14 s'étend sous forme d'une bande marginale
rectiligne, entre te quatrième côté de la première région 12
et le quatrième côté du contour précité, sur une longueur
légèrement supérieure à la dimension correspondante de la
région 12. Les plans des régions 13, 12 et 14 sont à des
distances croissantes de celui du fond 5 et ces régions se
raccordent entre elles par des décrochements dans la direction
axiale.The
Comme on le voit sur les figures 1 et 2, les deux coquilles
3 et 4 d'une même paire sont accolées entre elles par les
régions marginales 13 de leurs rebords extérieurs 10, les
régions annulaires 12, les régions marginales 14 et les
rebords intérieurs 9 des deux coquilles étant à des distances
mutuelles croissantes. Les deux régions 14 définissent entre
elles un logement pour l'extrémité d'un tube aplati 15
appartenant à une rangée de tubes dont chacun est associé à
l'une des paires de coquilles de la boíte collectrice. De
façon connue, les tubes de la rangée sont alignés alternativement
avec des intercalaires 16 sous forme de bandes
métalliques ondulées, les crêtes des ondulations d'une même
bande venant alternativement en contact avec deux tubes
voisins. De façon connue également, l'espace interne de
chaque tube est garni par une plaque perturbatrice 17
destinée à créer des turbulences dans l'écoulement du fluide
circulant dans le tube. La plaque perturbatrice est par
exemple constituée par une bande métallique ondulée dont les
crêtes d'ondulations viennent alternativement en contact avec
les deux faces internes opposées du tube, cette bande étant
en outre perforée pour permettre la circulation du fluide.As seen in Figures 1 and 2, the two
Selon l'invention, la plaque perturbatrice 17 fait saillie
au-delà de l'extrémité du tube, entre les deux coquilles 3 et
4, et vient en contact avec les régions annulaires 12 des
rebords extérieurs de celles-ci sensiblement sur toute
l'étendue de ces régions. Dans sa partie en saillie, la
plaque 17 est percée d'une ouverture circulaire 18, alignée
avec les ouvertures 8 des fonds des coquilles, d'un diamètre
voisin de celui des parois latérales 7, de façon à permettre
une libre communication entre les volumes internes 19
délimités par le fond 5 et la paroi latérale 7 de chaque
coquille.According to the invention, the
Comme le montrent également les figures 1 et 2, les paires 1
et 2 de coquilles sont mutuellement accolées et assemblées
par les faces extérieures des rebords intérieurs 9 de leurs
coquilles respectives tournées l'une vers l'autre, les jupes
périphériques 11 de ces mêmes coquilles étant en regard et à
une certaine distance l'une de l'autre. Les autres paires de
coquilles non représentées sont assemblées de la même façon
pour former l'empilement constitutif de la boíte collectrice,
les volumes internes 19 des différentes paires communiquant
entre eux par les ouvertures 8 pour former une chambre
interne s'étendant sur la longueur de la boíte collectrice,
avec laquelle communiquent les tubes 15. Cette chambre
interne est séparée de façon étanche de l'extérieur de
l'échangeur de chaleur par le brasage mutuel des rebords
intérieurs 9 accolés, celui des régions 13 accolées et le
brasage des régions 14, et des décrochements qui les relient
aux régions 13, sur les tubes 15.As also shown in Figures 1 and 2, pairs 1
and 2 of shells are mutually joined and assembled
by the outer faces of the inner edges 9 of their
respective shells facing each other, the skirts
peripherals 11 of these same shells being opposite and at
a certain distance from each other. The other pairs of
unrepresented shells are assembled in the same way
to form the constituent stack of the manifold,
