Description
La présente invention concerne un échangeur de chaleur, et plus particulièrement un échangeur de chaleur de type mécanique.The present invention relates to a heat exchanger, and more particularly to a mechanical type heat exchanger.
Un échangeur de chaleur comprend généralement des tubes, dans lesquels un fluide caloporteur est destiné à circuler, et des éléments d'échange de chaleur reliés à ces tubes.A heat exchanger generally comprises tubes, in which a heat transfer fluid is intended to circulate, and heat exchange elements connected to these tubes.
On distingue habituellement des échangeurs de chaleur de type brasé et de type mécanique selon leur procédé de fabrication.Brazed and mechanical type heat exchangers are usually distinguished by their manufacturing process.
Dans un échangeur de chaleur de type mécanique, les éléments d'échange de chaleur, appelés dans ce cas « ailettes >>, sont reliés aux tubes de la façon suivante. Tout d’abord, on forme dans les ailettes des trous de passage des tubes. Ces trous de passage sont généralement délimités chacun par un bord tombé formant un col. Puis, on dispose les ailettes sensiblement parallèlement entre elles et on enfile chaque tube dans une rangée de trous alignés des ailettes. Enfin, on provoque une expansion radiale des tubes en passant un outil d’expansion à l'intérieur de ces tubes de façon à lier mécaniquement les tubes et les ailettes par sertissage, les cols délimitant les trous de passage des tubes formant alors des collets serrés autour les tubes.In a mechanical type heat exchanger, the heat exchange elements, referred to in this case as "fins", are connected to the tubes in the following manner. First, the holes are formed in the fins passage tubes. These passage holes are generally delimited each by a fallen edge forming a neck. Then, the fins are arranged substantially parallel to each other and each tube is threaded into a row of aligned holes of the fins. Finally, it causes a radial expansion of the tubes by passing an expansion tool inside these tubes so as to mechanically bind the tubes and fins by crimping, the necks defining the passage holes of the tubes then forming tight collars around the tubes.
Les ailettes de ce type de tube sont en général fabriquées à partir de feuilles de métal lisses. L’invention a pour but de proposer un échangeur de chaleur dont les performances d’échange de chaleur sont améliorées tout en limitant sa masse. A cet effet, l’invention a pour objet un échangeur de chaleur comprenant au moins un tube de circulation de fluide caloporteur relié à au moins une ailette de dissipation de calories, caractérisé en ce que l’ailette est en feuille de métal déployé.The fins of this type of tube are usually made from smooth metal sheets. The object of the invention is to propose a heat exchanger whose heat exchange performance is improved while limiting its mass. For this purpose, the subject of the invention is a heat exchanger comprising at least one heat transfer fluid circulation tube connected to at least one calorific dissipation fin, characterized in that the fin is made of expanded metal foil.
Le fait que l’ailette soit en feuille de métal déployé permet d’augmenter l’échange thermique entre l’air et l’ailette tout en limitant la masse de l’échangeur de chaleur, car on augmente la surface d’échange de l’ailette par rapport à une feuille de métal lisse, sans pour autant y ajouter de matière.The fact that the fin is made of expanded metal sheet makes it possible to increase the heat exchange between the air and the fin while limiting the mass of the heat exchanger, because the exchange surface of the heat exchanger is increased. fin relative to a sheet of smooth metal, without adding material.
Dans un mode de réalisation particulier, correspondant à un échangeur de type mécanique, le tube est relié à l’ailette par serrage du tube dans un collet ménagé dans l’ailette.In a particular embodiment, corresponding to a mechanical type of exchanger, the tube is connected to the fin by clamping the tube in a collar formed in the fin.
De préférence, afin d’augmenter encore davantage l’échange de chaleur entre l’air et l’ailette, l’échangeur comprenant une rangée de tubes sensiblement parallèles, l’ailette comprend au moins une rangée de déflecteurs formant persienne, ménagée dans l’ailette et intercalée entre deux tubes de la rangée de tubes.Preferably, in order to further increase the heat exchange between the air and the fin, the exchanger comprising a row of substantially parallel tubes, the fin comprises at least one row of baffle deflectors formed in the louver. fin and interposed between two tubes of the row of tubes.
Dans un mode de réalisation particulier de l’invention, la feuille de métal déployé comprend des mailles ayant chacune une forme générale de losange.In a particular embodiment of the invention, the expanded metal sheet comprises meshes each having a general diamond shape.
De préférence, afin d’alléger l’échangeur de chaleur, le métal déployé de la feuille comprend de l’aluminium. L’invention concerne également un procédé de fabrication d’une ailette d’un échangeur de chaleur selon l’invention, l’ailette étant formée à partir d’une feuille de métal, caractérisé en ce que a) on comprime la feuille de métal entre deux rangées complémentaires de dents alignées respectivement portées par deux mâchoires d’une presse ; b) on déplace les deux rangées de dents d’un demi-pas, un pas correspondant à la distance entre les sommets consécutifs de deux dents d’une même rangée ; c) on déplace la feuille de métal transversalement aux rangées de dents d’une distance correspondant à la largeur d’une dent ; d) on réitère l’étape a) e) on déplace les deux rangées de dents d’un demi-pas dans le sens inverse à celui de l’étape b) f) on réitère les étapes a) à e), g) on forme des trous de passage de tube.Preferably, in order to lighten the heat exchanger, the expanded metal of the sheet comprises aluminum. The invention also relates to a method of manufacturing a fin of a heat exchanger according to the invention, the fin being formed from a sheet of metal, characterized in that a) the metal sheet is compressed between two complementary rows of aligned teeth carried respectively by two jaws of a press; b) the two rows of teeth are displaced by half a step, a step corresponding to the distance between the consecutive vertices of two teeth of the same row; c) moving the metal sheet transversely to the rows of teeth by a distance corresponding to the width of a tooth; d) repeating step a) e) moving the two rows of teeth by half a step in the opposite direction to that of step b) f) repeating steps a) to e), g) Tube passage holes are formed.
Dans un mode de réalisation particulier, le procédé comporte l’étape supplémentaire de former des persiennes entre lesdits trous de passage. L'invention sera mieux comprise à la lecture de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels : - la figure 1 est une vue partielle en perspective d’une ailette d’un échangeur de chaleur selon un mode de réalisation particulier de l’invention ; - les figures 2 à 7 sont des vues schématiques en perspective d’une presse de fabrication d’une ailette au cours de différentes étapes d’un procédé de fabrication de l’ailette selon un mode de réalisation particulier de l’invention. - la figure 8 est une vue schématique d’un échangeur selon l’invention.In a particular embodiment, the method comprises the additional step of forming louvers between said through holes. The invention will be better understood on reading the following description given solely by way of example and with reference to the drawings in which: - Figure 1 is a partial perspective view of a fin of a heat exchanger of heat according to a particular embodiment of the invention; - Figures 2 to 7 are schematic perspective views of a fin manufacturing press during different stages of a fin manufacturing method according to a particular embodiment of the invention. FIG. 8 is a schematic view of an exchanger according to the invention.
On a représenté à la figure 1 une ailette d’un échangeur de chaleur 1 de type mécanique destiné à équiper un véhicule automobile. L'échangeur de chaleur comprend une rangée de tubes 2 sensiblement parallèles, dans lesquels un fluide caloporteur classique est destiné à circuler, et des ailettes 4 de dissipation de chaleur superposées reliées à ces tubes 2.FIG. 1 shows a fin of a heat exchanger 1 of mechanical type intended to equip a motor vehicle. The heat exchanger comprises a row of substantially parallel tubes 2, in which a conventional heat transfer fluid is intended to circulate, and superimposed heat dissipating fins 4 connected to these tubes 2.
Les tubes 2 sont reliés aux ailettes 4 par serrage des tubes dans des collets 6 ménagés dans les ailettes 4. A cet effet, les ailettes 4 sont munies de trous 8 de passage des tubes. Ces trous de passage 8 sont chacun délimités par un bord formant un collet 6 et présentant deux portions de bord longues reliées par deux petites portions de bord en demi-cercle. Les trous de passage ont chacun une forme générale oblongue avec les portions longues qui sont légèrement concaves en leur milieu.The tubes 2 are connected to the fins 4 by clamping the tubes in collars 6 formed in the fins 4. For this purpose, the fins 4 are provided with holes 8 for passage of the tubes. These through holes 8 are each delimited by an edge forming a collar 6 and having two long edge portions connected by two small portions of semicircular edge. The through holes each have a generally oblong shape with long portions that are slightly concave in their middle.
Dans l'exemple décrit, les tubes 2 ont chacun une forme correspondant à celle décrite pour les trous de passage. Les tubes 2 sont agencés sensiblement parallèlement entre eux, de façon à former une rangée unique.In the example described, the tubes 2 each have a shape corresponding to that described for the through holes. The tubes 2 are arranged substantially parallel to each other, so as to form a single row.
Les ailettes 4 ont une forme générale rectangulaire, sensiblement plane, et sont agencées dans l'échangeur de chaleur 1 de façon sensiblement parallèle entre elles et perpendiculaire aux directions longitudinales des tubes 2. L’échangeur 1 permet la circulation d’un flux d’air d’amont en aval, les ailettes 4 étant destinées à s’étendre à travers ce flux. On a représenté sur la figure 1 par des flèches F la direction de circulation du flux.The fins 4 have a generally rectangular shape, substantially flat, and are arranged in the heat exchanger 1 substantially parallel to each other and perpendicular to the longitudinal directions of the tubes 2. The exchanger 1 allows the flow of a flow of upstream air downstream, the fins 4 being intended to extend through this flow. FIG. 1 shows by arrows F the flow direction of flow.
Pour augmenter l’échange thermique entre le flux F et les ailettes 4, l’échangeur 1 comprend également des rangées 10 de déflecteurs 12 formant persiennes, ménagées dans chaque ailette 4 et intercalées chacune entre deux tubes 2. L’ailette 4 est en feuille de métal déployé, et par conséquent les déflecteurs 10 également. De préférence, le métal de la feuille comprend de l’aluminium, par exemple un alliage comprenant essentiellement de l’aluminium.To increase the heat exchange between the flow F and the fins 4, the exchanger 1 also comprises rows of baffles 12 forming louvers, formed in each fin 4 and each interposed between two tubes 2. The fin 4 is a sheet expanded metal, and therefore deflectors 10 as well. Preferably, the metal of the sheet comprises aluminum, for example an alloy comprising essentially aluminum.
Plus particulièrement, la feuille de métal déployé comprend des mailles 12 ayant chacune une forme de losange.More particularly, the expanded metal sheet comprises meshes 12 each having a diamond shape.
On va maintenant décrire un procédé de fabrication d’une ailette 4 d’un échangeur de chaleur 1 selon l’invention dont les étapes sont illustrées aux figures 2 à 7. L’ailette 4 étant formée à partir d’une feuille 16 de métal, on commence par comprimer cette feuille de métal 16 entre deux rangées 18 complémentaires de dents 20 alignées respectivement portées par deux mâchoires 22 d’une presse 24.We will now describe a method of manufacturing a fin 4 of a heat exchanger 1 according to the invention, the steps of which are illustrated in FIGS. 2 to 7. The fin 4 being formed from a sheet 16 of metal , this metal sheet 16 is first compressed between two complementary rows 18 of aligned teeth 20 carried respectively by two jaws 22 of a press 24.
Ceci est par exemple réalisé en abaissant la mâchoire 22 supérieure selon la direction et le sens représentées par la flèche C de la figure 2, la compression étant illustrée à la figure 3.This is for example achieved by lowering the upper jaw 22 in the direction and the direction represented by the arrow C of FIG. 2, the compression being illustrated in FIG.
Puis, on déplace les deux rangées 18 de dents d’un demi-pas, un pas correspondant à la distance p entre les sommets consécutifs de deux dents 20 d’une même rangée 18. Ce déplacement est représenté par la flèche Pi de la figure 4.Then, the two rows 18 of teeth are displaced by half a step, a step corresponding to the distance p between the consecutive vertices of two teeth 20 of the same row 18. This displacement is represented by the arrow Pi of FIG. 4.
On déplace ensuite la feuille de métal 16 transversalement aux rangées 18 de dents d’une distance d correspondant à la largeur d’une dent 20. Ce déplacement est représenté par la flèche D représentée à la figure 5.The metal sheet 16 is then moved transversely to the rows 18 of teeth by a distance d corresponding to the width of a tooth 20. This movement is represented by the arrow D shown in FIG.
Après avoir réitéré l’étape de compression entre les rangées 18 de dents 20 comme représenté aux figures 5 et 6, on déplace les deux rangées 18 de dents 20 d’un demi-pas dans le sens inverse de la flèche P15 c’est-à-dire dans le sens de la flèche P2, représentée à la figure 7.After repeating the compression step between the rows 18 of teeth 20 as shown in FIGS. 5 and 6, the two rows 18 of teeth 20 are moved half a step in the opposite direction of the arrow P15. that is, in the direction of arrow P2, shown in FIG.
Pour obtenir l’ailette 4 en métal déployé tel que représentée sur la figure 1, on réitère les étapes ci-dessus jusqu’à ce que toute la surface de la feuille 16 ait été comprimée, puis on réalise les trous et les persiennes. L'invention n'est pas limitée au mode de réalisation présenté et d'autres modes de réalisation apparaîtront clairement à l'homme du métier. Par exemple, selon un mode de réalisation non représenté, les tubes sont de section circulaire et les trous de passage correspondants sont circulaires.To obtain the fin 4 of expanded metal as shown in Figure 1, it repeats the above steps until the entire surface of the sheet 16 has been compressed, then the holes and louvers are made. The invention is not limited to the embodiment shown and other embodiments will become apparent to those skilled in the art. For example, according to an embodiment not shown, the tubes are of circular section and the corresponding through holes are circular.
