Abstract
Description
L'invention concerne un échangeur de chaleur à faisceau de tubes tel par exemple qu'un radiateur faisant partie d'un circuit de refroidissement de moteur ou d'un circuit de chauffage ou de climatisation de l'habitacle d'un véhicule automobile. The invention relates to a tube bundle heat exchanger such as a radiator forming part of an engine cooling circuit or a heating or air conditioning circuit of the passenger compartment of a motor vehicle.
On sait qu'un échangeur de chaleur comprend en général un faisceau de tubes ou de conduits parcourus par un fluide primaire (par exemple le liquide de refroidissement d'un moteur) et des éléments de transfert de chaleur tels que des ailettes, associés aux tubes et balayés par un fluide secondaire (par exemple de l'air). It is known that a heat exchanger generally comprises a bundle of tubes or conduits traversed by a primary fluid (for example the coolant of an engine) and heat transfer elements such as fins, associated with the tubes and swept away by a secondary fluid (e.g. air).
L'invention a pour but de réaliser une économie substantielle sur la fabrication de tels échangeurs, en diminuant le nombre de leurs composants et/ou la quantité de matière première les constituant, et cela sans modifier leurs dimensions et sans nuire à leur efficacité. The object of the invention is to achieve a substantial saving in the manufacture of such exchangers, by reducing the number of their components and / or the quantity of raw material constituting them, without changing their dimensions and without affecting their efficiency.
ville propose pour cela un faisceau d'échangeur de chaleur comprenant des tubes ou conduits parcourus par un fluide primaire et des éléments de transfert de chaleur associés aux tubes et balayés par un fluide secondaire, caractérisé en ce que la densité de répartition des tubes et/ou des éléments de transfert de chaleur varie entre la périphérie et la partie centrale du faisceau et, avantageusement, est plus importante dans la partie centrale qu'à la périphérie. ville offers for this a heat exchanger bundle comprising tubes or conduits traversed by a primary fluid and heat transfer elements associated with the tubes and swept by a secondary fluid, characterized in that the distribution density of the tubes and / or heat transfer elements varies between the periphery and the central part of the bundle and, advantageously, is greater in the central part than at the periphery.
Selon une autre caractéristique de l'invention, visant le cas où les tubes sont disposés en au moins une rangée, la distance entre tubes diminue progressivement depuis les extrémités de la rangée vers sa partie centrale. According to another characteristic of the invention, targeting the case where the tubes are arranged in at least one row, the distance between tubes decreases progressively from the ends of the row towards its central part.
Selon une autre caractéristique de l'invention, visant le cas où les éléments de transfert de chaleur sont des ailettes sensiblement parallèles traversées par les tubes, la distance entre ailettes diminue progressivement depuis les ailettes d'extrémités vers les ailettes situées au milieu de la série d'ailettes. According to another characteristic of the invention, targeting the case where the heat transfer elements are substantially parallel fins traversed by the tubes, the distance between fins progressively decreases from the end fins to the fins located in the middle of the series. of fins.
son effet, en raison de l'effet de paroi selon lequel la vitesse d'un fluide circulant dans un conduit est plus faible au voisinage immédiat de la paroi du conduit qu'à distance de cette paroi, d'une part, le débit de fluide primaire est, sauf disposition spéciale de la botte à eau, moins important dans les tubes d'extrémité du faisceau que dans les tubes centraux et, d'autre part, le débit de fluide secondaire à travers le faisceau est moins important à la périphérie du faisceau qu'en son centre, de sorte que l'échange de chaleur est plus faible à la périphérie du faisceau qu'à sa partie centrale. its effect, due to the wall effect according to which the speed of a fluid circulating in a conduit is lower in the immediate vicinity of the wall of the conduit than at a distance from this wall, on the one hand, the flow of primary fluid is, unless special provision of the water boot, less important in the end tubes of the bundle than in the central tubes and, on the other hand, the flow of secondary fluid through the bundle is less important at the periphery of the beam than at its center, so that the heat exchange is weaker at the periphery of the beam than at its central part.
En conséquence, le nombre de tubes et/ou d'éléments de transfert de chaleur peut etre réduit à la périphérie du faisceau, c'est-à-dire plus faible qu'au centre, sans diminuer pour autant le rendement ou l'efficacité de l'échangeur. Consequently, the number of tubes and / or heat transfer elements can be reduced at the periphery of the bundle, that is to say lower than at the center, without reducing the yield or the efficiency. of the exchanger.
L'invention concerne également un échangeur de chaleur caractérisé en ce qu'il comprend un faisceau de tubes du type décrit ci-dessus. The invention also relates to a heat exchanger characterized in that it comprises a bundle of tubes of the type described above.
Dans la description qui suit, faite à titre d'exemple, on se réfère aux dessins schématiques annexés, dans lesquels
- la figure 1 est une vue schématique en perspective d'un faisceau de tubes à ailettes selon l'invention
- la figure 2 est une vue schématique partielle en perspective d'une autre forme de réalisation de l'invention et
- la fieure 3 est une vue schématique partielle de face d'encore une autre forme de réalisation de l'invention.In the following description, given by way of example, reference is made to the appended schematic drawings, in which
- Figure 1 is a schematic perspective view of a bundle of finned tubes according to the invention
FIG. 2 is a partial schematic perspective view of another embodiment of the invention and
- the flower 3 is a partial schematic front view of yet another embodiment of the invention.
Le faisceau 10 représenté en figure 1 comprend des plaques parallèles Il qui sont traversées, par exemple perpendi culairement, par des tubes par pèles 12 alignés en une rangée. The bundle 10 shown in FIG. 1 comprises parallel plates II which are traversed, for example perpendicularly, by tubes by spikes 12 aligned in a row.
Les tubes 12 sont cylindriques à section circulaire et sont destinés à former les tubes de circulation de fluide primaire dans un échangeur de chaleur, tel qu'un radiateur faisant partie d'un circuit de refroidissement de moteur ou d'un circuit de chauffage ou de climatisation de l'habitacle d'un véhicule automobile.The tubes 12 are cylindrical with a circular section and are intended to form the primary fluid circulation tubes in a heat exchanger, such as a radiator forming part of an engine cooling circuit or of a heating or air conditioning of the passenger compartment of a motor vehicle.
Comme cela est bien connu, un tel échangeur comprend en général deux bottes à eau (non représentées) qui sont montées de part et d'autre du faisceau 10 de telle sorte que les extrémités des tubes 12 débouchent dans ces bottes à eau. As is well known, such an exchanger generally comprises two water boots (not shown) which are mounted on either side of the bundle 10 so that the ends of the tubes 12 open into these water boots.
Celles-ci comprennent des conduites d'amenée et de retour du liquide les reliant au circuit de refroidissement, de chauffage ou de climatisation. L'échangeur est monté dans le véhicule en un endroit approprié, de telle sorte que le faisceau 10 soit balayé par un fluide secondaire qui est en général de l'air. Le fluide primaire amené dans une des bottes à eau circule dans les tubes 12, est refroidi ou chauffé par le fluide secondaire qui balaye les plaques 11, puis gagne la conduite de retour vers le circuit par l'intermédiaire d'une des bottes à eau.These include liquid supply and return lines connecting them to the cooling, heating or air conditioning circuit. The exchanger is mounted in the vehicle in a suitable location, so that the bundle 10 is swept by a secondary fluid which is generally air. The primary fluid brought into one of the water boots circulates in the tubes 12, is cooled or heated by the secondary fluid which scans the plates 11, then gains the return line towards the circuit via one of the water boots .
Ies tubes 12 peuvent être à disposition horizontale, verticale ou inclinée. Le faisceau 10 (ou bien l'échangeur complet) peut entre placé transversalement dans une canalisation de passage du fluide secondaire ou bien simplement placé à l'air libre. Ies tubes 12 can be available horizontally, vertically or inclined. The bundle 10 (or else the complete exchanger) can between placed transversely in a pipe for the passage of the secondary fluid or else simply placed in the open air.
Dans un échangeur classique de la technique antérieure, la distance d entre deux tubes 12 voisins est constante pour tous les tubes et l'intervalle e séparant deux plaques 11 voisines est également constant. In a conventional exchanger of the prior art, the distance d between two neighboring tubes 12 is constant for all the tubes and the interval e separating two neighboring plates 11 is also constant.
Selon l'invention, la distance d et/ou l'intervalle e varient de façon progressive en fonction de la position des tubes 12 dans la rangée de tubes représentée et de la position des plaques Il dans la série de plaques représentée, respectivement. According to the invention, the distance d and / or the interval e vary progressively as a function of the position of the tubes 12 in the row of tubes shown and the position of the plates II in the series of plates shown, respectively.
De façon plus précise, la distance d séparant deux tubes 12 voisins ou consécutifs diminue progressivement à partir des tubes d'extrémités 12a de la rangée vers les tubes centraux 12b de cette rangée. La distance e diminue progressivement à partir des plaques 11a d'extrémités vers les plaques centrales llb. More precisely, the distance d separating two neighboring or consecutive tubes 12 progressively decreases from the end tubes 12a of the row towards the central tubes 12b of this row. The distance e gradually decreases from the end plates 11a towards the central plates 11b.
 titre d'exemple, on précisera que, pour un échangeur tel qu'un radiateur faisant partie d'un circuit de refroidissement de véhicule automobile, dont le faisceau 10 comprend trente tubes 12 ayant un diamètre de 8 millimètres, répartis en deux rangées parallèles, la distance d entre tubes 12 d'une mtme rangée varie de 30 millimètres à l'extrémité de la rangée à 18 millimètres au milieu de la rangée. L'intervalle e entre les plaques 11 qui forment les ailettes des tubes 12 et qui sont des feuilles d'aluminium ayant une épaisseur de 0,1 millimètre environ, varie de 2 millimètres aux extrémités du faisceau à environ 1 millimètre au milieu du faisceau. As an example, it will be specified that, for an exchanger such as a radiator forming part of a motor vehicle cooling circuit, the bundle 10 of which comprises thirty tubes 12 having a diameter of 8 millimeters, distributed in two parallel rows , the distance d between tubes 12 of a same row varies from 30 millimeters at the end of the row to 18 millimeters in the middle of the row. The interval e between the plates 11 which form the fins of the tubes 12 and which are aluminum sheets having a thickness of approximately 0.1 millimeter, varies from 2 millimeters at the ends of the beam to approximately 1 millimeter in the middle of the beam.
Pour un échangeur classique correspondant, la distance d constante entre tubes d'une rangée est de 20 millimètres et l'intervalle e entre les plaques Il est de 1,5 millimètre.For a corresponding conventional exchanger, the constant distance d between tubes of a row is 20 millimeters and the interval e between the plates It is 1.5 millimeters.
L'accroissement de la distance entre deux tubes consécutifs du centre vers les extrémités d'une rangée de tubes et de l'intervalle entre plaques consécutives du centre du faisceau vers les extrémités, signifie qu'un faisceau d'échangeur de chaleur selon l'invention comprend moins de tubes et moins de plaques qu'un échangeur classique correspondant et que son prix de revient en est d'autant diminué. Toutefois, cette diminution du nombre de tubes du faisceau n'affecte pas de façon sensible la circulation du liquide ou du fluide primaire dans l'échangeur et, de même, la diminution du nombre de plaques ou d'ailettes des tubes n'affecte pas l'échange thermique entre le fluide primaire et le fluide secondaire. The increase in the distance between two consecutive tubes from the center to the ends of a row of tubes and the interval between consecutive plates from the center of the beam to the ends means that a heat exchanger bundle along the invention comprises fewer tubes and fewer plates than a corresponding conventional exchanger and that its cost price is correspondingly reduced. However, this reduction in the number of tubes in the bundle does not appreciably affect the circulation of the liquid or the primary fluid in the exchanger and, likewise, the reduction in the number of plates or fins of the tubes does not affect the heat exchange between the primary fluid and the secondary fluid.
L'invention permet donc d'obtenir un échangeur de chaleur dont le faisceau a les mêmes dimensions qu'un échangeur classique et présente la mme efficacité ou le mame rendement, mais est d'un prix de revient et également d'un poids plus faibles. The invention therefore makes it possible to obtain a heat exchanger whose bundle has the same dimensions as a conventional exchanger and has the same efficiency or the same efficiency, but is of a cost price and also of a lower weight. .
Avantageusement, les lois de variation de la distance entre tubes et de l'intervalle entre plaques sont linéaires. Advantageously, the laws of variation of the distance between tubes and of the interval between plates are linear.
On se réfère maintenant à la figure 2 qui représente schématiquement une variante de réalisation de 1' invention. Reference is now made to FIG. 2 which schematically represents an alternative embodiment of the invention.
Dans cette variante, les tubes 15 du faisceau 16 sont des tubes plats à section transversale très oblongue ou très allongée qui s'détendent parallèlement les uns aux autres dans le faisceau 16. Les tubes plats 15 sont séparés les uns des autres par des éléments 17 de transfert de chaleur, qui sont des plaques minces, par exemple en aluminium, pliées en accordéon ou en zigzag et qui sont fixées, par exemple soudées, à leurs sommets sur les parois extérieures des tubes 15. In this variant, the tubes 15 of the bundle 16 are flat tubes of very oblong or very elongated cross section which extend parallel to each other in the bundle 16. The flat tubes 15 are separated from each other by elements 17 of heat transfer, which are thin plates, for example of aluminum, folded in an accordion or zigzag shape and which are fixed, for example welded, at their apices on the external walls of the tubes 15.
Selon l'invention, la distance entre deux tubes plats 15 voisins ou consécutifs diminue progressivement des extrémités du faisceau vers sa partie centrale et/ou la distance entre deux plis 17a, 17b d'un élément 17 de transfert de chaleur diminue progressivement des extrémités ou de la périphérie du faisceau vers sa partie centrale. According to the invention, the distance between two neighboring or consecutive flat tubes 15 progressively decreases from the ends of the bundle towards its central part and / or the distance between two plies 17a, 17b of a heat transfer element 17 progressively decreases from the ends or from the periphery of the beam to its central part.
De manière générale, les éléments 17 de transfert de chaleur s'étendent sur toute la hauteur du faisceau 16, mais on peut prévoir que le ou les éléments 17 les plus proches d'un bord d'extrémité du faisceau 16 auront une longueur inférieure à celle des autres éléments et s'arrêteront par exemple à une certaine distance de la périphérie du faisceau 16, comme représenté en figure 2 pour l'élément 17 de gauche. Generally, the heat transfer elements 17 extend over the entire height of the bundle 16, but it can be expected that the element or elements 17 closest to an end edge of the bundle 16 will have a length less than that of the other elements and will stop for example at a certain distance from the periphery of the beam 16, as shown in FIG. 2 for the element 17 on the left.
On se réfère maintenant à la figure 3 qui représente encore une autre forme de réalisation de l'invention, selon laquelle les tubes 20 du faisceau 21 sont associés à des éléments de transfert de chaleur formés par des plaques planes ou ailettes 22, comme dans la forme de réalisation de la figure 1. Les tubes 20 sont cylindriques à section circulaire, ovale, oblongue ou aplatie, par exemple. Reference is now made to FIG. 3 which represents yet another embodiment of the invention, according to which the tubes 20 of the bundle 21 are associated with heat transfer elements formed by flat plates or fins 22, as in the embodiment of FIG. 1. The tubes 20 are cylindrical with a circular, oval, oblong or flattened section, for example.
Selon l'invention, la distance entre tubes 20 diminue progressivement de la périphérie du faisceau jusque vers sa partie centrale et la distance entre plaques ou ailettes 22 diminue également de la périphérie du faisceau jusqu'à sa partie centrale. Avantageusement, les plaques ou ailettes 22 qui sont les plus proches de la périphérie du faisceau peuvent être de longueur plus faible et ne s'étendent pas jusqu'au bord du faisceau. Dans l'exemple représenté en figure 3, l'ailette d'extrémité 221, voisine d'une extrémité des tubes 20, s'étend sur toute l'étendue du faisceau, de façon classique, mais l'ailette suivante 222 n'est associée qu'aux tubes de la zone centrale du faisceau et s'arr8te avant les tubes 20 d'extrémités. According to the invention, the distance between tubes 20 progressively decreases from the periphery of the bundle to its central part and the distance between plates or fins 22 also decreases from the periphery of the bundle to its central part. Advantageously, the plates or fins 22 which are closest to the periphery of the bundle can be of shorter length and do not extend to the edge of the bundle. In the example shown in FIG. 3, the end fin 221, close to one end of the tubes 20, extends over the entire extent of the bundle, in a conventional manner, but the following fin 222 is not associated with the tubes in the central zone of the bundle and stops before the end tubes 20.
On peut ainsi alterner, sur une certaine hauteur, des ailettes de dimensions normales et des ailettes de dimensions inférieures. It is thus possible to alternate, over a certain height, fins of normal dimensions and fins of smaller dimensions.
Dans tous les cas, la densité de répartition des tubes et/ou des éléments de transfert de chaleur associés aux tubes varie progressivement entre la périphérie et la partie centrale du faisceau de l'échangeur de chaleur. In all cases, the distribution density of the tubes and / or of the heat transfer elements associated with the tubes varies progressively between the periphery and the central part of the bundle of the heat exchanger.
