Description

L'invention concerne un échangeur de chaleur selon le préambule de la revendication.The invention relates to a heat exchanger according to the preamble of the claim.

Dans la plaque collectrice d'un tel échangeur connu par FR 2 538 526 , la région périphérique se raccorde à une portion marginale de la platine s'étendant tout autour de l'ensemble des collets.In the collector plate of such an exchanger known by FR 2,538,526 , the peripheral region connects to a marginal portion of the plate extending all around the set of collars.

Le but de l'invention est de réduire l'encombrement de la plaque collectrice par rapport à cette réalisation connue.The object of the invention is to reduce the bulk of the collector plate with respect to this known embodiment.

L'invention vise notamment un échangeur de chaleur selon les revendications 1 à 6.The invention relates in particular to a heat exchanger according to claims 1 to 6.

L'invention a également pour objet une plaque collectrice selon la revendication 7.The invention also relates to a collector plate according to claim 7.

Les avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés, sur lesquels:

  • la figure 1 est une vue en perspective partiellement arrachée montrant une plaque collectrice selon l'invention associée à une boîte à fluide et à un faisceau de tubes;
  • la figure 2 est une vue de dessus de la plaque collectrice illustrée à la figure 1; et
  • les figures 3 à 5 sont des vues partielles en coupe selon les lignes III-III, IV-IV et V-V de la figure 2.
The advantages of the invention will be described in more detail in the description below, with reference to the accompanying drawings, in which:
  • the figure 1 is a partially cutaway perspective view showing a header plate according to the invention associated with a fluid box and a bundle of tubes;
  • the figure 2 is a top view of the collector plate illustrated at figure 1 ; and
  • the Figures 3 to 5 are partial sectional views along the lines III-III, IV-IV and VV of the figure 2 .

La plaque collectrice 1 représentée sur les figures, réalisée en tôle métallique emboutie, comprend une région périphérique 2 définissant un canal annulaire présentant une paroi latérale intérieure 3, un fond 4 et une paroi latérale extérieure 5. Ce canal sert à loger le bord périphérique 6 d'une boîte à fluide 7 en forme de bac, ainsi qu'un joint d'étanchéité 8. Après assemblage, le bord libre 9 de la paroi extérieure 5 est rabattu par sertissage sur le bord 6 de la boîte à fluide pour immobiliser celle-ci et comprimer le joint 8 entre le bord 6 et le fond 4 du canal. La plaque collectrice est représentée avant sertissage aux figures 2 à 5.The collector plate 1 shown in the figures, made of stamped metal sheet, comprises a peripheral region 2 defining an annular channel having an inner side wall 3, a bottom 4 and an outer side wall 5. This channel serves to house the peripheral edge 6 a fluid box 7 shaped tray, and a seal 8. After assembly, the free edge 9 of the outer wall 5 is folded by crimping on the edge 6 of the fluid box to immobilize the and compress the seal 8 between the edge 6 and the bottom 4 of the channel. The collector plate is shown before crimping to Figures 2 to 5 .

L'échangeur de chaleur partiellement illustré à la figure 1 comprend également un faisceau de tubes 10 constitué par une rangée de tubes 11 ayant chacun une section transversale oblongue allongée dans la direction de la largeur de la plaque collectrice, écartés les uns des autres, sur la majeure partie de leur longueur, par des intercalaires 12 sous forme de bandes ondulées. Chaque tube 11 traverse une ouverture 13 de forme correspondante ménagée dans la région centrale de la plaque collectrice, cette ouverture étant entourée par un collet incliné 14. Ainsi, l'extrémité de chaque tube débouche dans le volume intérieur 15 de la boîte à fluide, les intercalaires 12 étant situés à l'extérieur de ce volume.The heat exchanger partially illustrated at the figure 1 also comprises a bundle of tubes 10 consisting of a row of tubes 11 each having an oblong cross-section elongate in the width direction of the header plate, spaced apart from each other, over most of their length, by spacers 12 in the form of corrugated strips. Each tube 11 passes through a correspondingly shaped opening 13 formed in the central region of the collecting plate, this opening being surrounded by an inclined collar 14. Thus, the end of each tube opens into the internal volume 15 of the fluid box, tabs 12 being located outside this volume.

De façon connue, le long de chacun des deux grands côtés du canal périphérique 3-5 de contour rectangulaire, la paroi intérieure 3 de celui-ci se raccorde aux extrémités des collets 14 par l'intermédiaire d'un rebord 16 orienté sensiblement perpendiculairement à la direction longitudinale des tubes. Les deux rebords 16 forment, avec les fonds de vallées 17 comprises entre les collets 14, une platine s'étendant sensiblement selon un plan perpendiculaire à la direction précitée. En réalité, la platine n'est pas tout à fait plane, les rebords 16 ayant une forme légèrement ondulée de façon à limiter les contraintes mécaniques lors de la fabrication de la plaque collectrice.In known manner, along each of the two long sides of the peripheral channel 3-5 of rectangular contour, the inner wall 3 thereof is connected to the ends of the collars 14 via a flange 16 oriented substantially perpendicular to the longitudinal direction of the tubes. The two flanges 16 form, with the valley bottoms 17 between the flanges 14, a plate extending substantially in a plane perpendicular to the aforementioned direction. In fact, the plate is not quite flat, the flanges 16 having a slightly undulated shape so as to limit the mechanical stresses during the manufacture of the header plate.

Selon l'invention, la platine ne comporte pas de rebord le long des petits côtés du canal périphérique, où la paroi intérieure du canal se raccorde directement au flanc extérieur du collet extrême de la rangée pour former un plan incliné unique 18. Cette disposition diminue l'encombrement de l'échangeur de chaleur dans la direction longitudinale de la plaque collectrice de deux fois la largeur du rebord 16. En outre, le plan incliné 18 est plus incliné par rapport au plan général de la platine que les autres flancs des collets 14, ce qui réduit encore cet encombrement. Compte tenu du rayon des arrondis formés par le canal 3-5 dans les angles de la plaque collectrice, les collets d'extrémités se raccordent directement à la paroi intérieure du canal, également à leurs extrémités, selon des surfaces inclinées 19, de sorte que seuls les collets intermédiaires sont séparés du canal par les rebords 16. En variante, comme indiqué en trait interrompu à la figure 3, le plan incliné 18 peut présenter sensiblement la même inclinaison par rapport au plan général de la platine que les autres flancs des collets et former un dièdre obtus avec la paroi 3 du canal, perpendiculaire à ce plan.According to the invention, the plate has no flange along the short sides of the peripheral channel, where the inner wall of the channel is connected directly to the outer flank of the extreme neck of the row to form a single inclined plane 18. This provision decreases the size of the heat exchanger in the longitudinal direction of the collector plate by twice the width of the rim 16. In addition, the inclined plane 18 is more inclined relative to the general plane of the plate than the other flanks of the collars 14, which further reduces this clutter. Given the radius of the roundings formed by the channel 3-5 in the corners of the header plate, the end collars connect directly to the inner wall of the channel, also at their ends, along inclined surfaces 19, so that only the intermediate collars are separated from the channel by the flanges 16. In a variant, as indicated in broken line at the figure 3 , the inclined plane 18 may have substantially the same inclination relative to the general plane of the plate as the other flanks of the collars and form a dihedral obtuse with the wall 3 of the channel, perpendicular to this plane.

Une autre variante prévoit le raccordement direct des collets aux parois du canal non pas sur toute la largeur de la plaque collectrice, mais sur toute sa longueur, réduisant ainsi l'encombrement de l'échangeur de chaleur dans la direction de la largeur.Another variant provides for the direct connection of the collars to the walls of the channel not over the entire width of the collector plate, but over its entire length, thus reducing the size of the heat exchanger in the direction of the width.
