Description
Échangeur de chaleur et procédé de refroidissement utilisant un fluide caloporteur à différentes températures
L'invention concerne les échangeurs de chaleur, en particulier pour véhicules automobiles.Heat exchanger and cooling method using a coolant at different temperatures
The invention relates to heat exchangers, in particular for motor vehicles.
Pour refroidir un moteur à combustion interne d'un véhicule automobile, on utilise classiquement un circuit de refroidissement propre à faire circuler un fluide caloporteur, généralement de l'eau additionnée d'antigel, à travers le bloc moteur pour y prélever de l'énergie calorifique et la restituer au milieu extérieur par échange thermique avec de l'air dans un échangeur de chaleur, communément appelé radiateur de refroidissement.To cool an internal combustion engine of a motor vehicle, conventionally a cooling circuit suitable for circulating a heat transfer fluid, generally water with antifreeze, through the engine block to draw energy there. calorific and return it to the outside environment by heat exchange with air in a heat exchanger, commonly called cooling radiator.
Il est connu également d'utiliser ce fluide caloporteur dans un ou plusieurs circuits de refroidissement secondaires, notamment pour refroidir l'huile de lubrification du moteur ou encore pour refroidir l'air de suralimentation provenant d'un turbo-compresseur.It is also known to use this heat transfer fluid in one or more secondary cooling circuits, in particular for cooling the lubricating oil of the engine or also for cooling the charge air coming from a turbo-compressor.
Pour limiter l'encombrement et le coût de l'ensemble des circuits, FR-A-2 634 546 propose d'y utiliser le même radiateur pour le refroidissement du fluide caloporteur. Ce document décrit donc un échangeur de chaleur multiple pour au moins deux circuits de refroidissement, comprenant au moins une boîte à fluide divisée en au moins deux compartiments par une cloison, et un faisceau de tubes de circulation de fluide caloporteur comportant au moins une rangée de tubes sensiblement parallèles et alignés en des positions régulièrement espacées les unes des autres, chaque compartiment communiquant avec un sous-ensemble des tubes de la rangée.To limit the size and the cost of all the circuits, FR-A-2 634 546 proposes to use the same radiator for cooling the heat transfer fluid. This document therefore describes a multiple heat exchanger for at least two cooling circuits, comprising at least one fluid box divided into at least two compartments by a partition, and a bundle of heat transfer fluid circulation tubes comprising at least one row of substantially parallel tubes aligned in regularly spaced positions from each other, each compartment communicating with a subset of the tubes in the row.
La température du fluide caloporteur parcourant les tubes de circulation peut être très différente, au moins dans certaines phases de fonctionnement, entre deux sous-ensembles voisins faisant partie de deux circuits de refroidissement différents. Lorsque les tubes sont reliés de façon rigide à la boîte à fluide, par exemple par brasage à la plaque perforée ou collecteur qui limite celle-ci, et sont également reliés entre eux de façon rigide à leur extrémité opposée, notamment par l'intermédiaire d'une autre boîte à fluide, la différence de dilatation résultant de cette différence de température entraîne des contraintes mécaniques excessives.The temperature of the heat transfer fluid passing through the circulation tubes can be very different, at least in certain operating phases, between two neighboring sub-assemblies forming part of two different cooling circuits. When the tubes are rigidly connected to the fluid box, for example by brazing to the perforated plate or collector which limits the latter, and are also rigidly connected to each other at their opposite end, in particular by means of 'Another fluid box, the difference in expansion resulting from this temperature difference causes excessive mechanical stresses.
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 multiple tel que défini ci-dessus, et prévoit que l'une desdites positions, adjacente à ladite cloison, est occupée par un élément allongé parallèle auxdits tubes et dans lequel le fluide caloporteur ne circule pas.The invention relates in particular to a multiple heat exchanger as defined above, and provides that one of said positions, adjacent to said partition, is occupied by an elongated element parallel to said tubes and in which the heat transfer fluid does not circulate.
D'autres caractéristiques, complémentaires ou alternatives, de l'invention sont énoncées ci-après - Les tubes de circulation traversent une paroi perforée, ou collecteur, limitant la boite à fluide et à laquelle ils sont brasés de façon étanche au fluide caloporteur.Other characteristics, complementary or alternative, of the invention are set out below - The circulation tubes pass through a perforated wall, or manifold, limiting the fluid box and to which they are brazed in a sealed manner to the heat transfer fluid.
- L'écartement mutuel des tubes de circulation et dudit élément allongé dans la rangée est défini par des intercalaires fixés à ceux-ci par brasage.- The mutual spacing of the circulation tubes and of said elongated element in the row is defined by spacers fixed to them by brazing.
- Ledit élément allongé est un tube analogue aux tubes de circulation, interrompu de façon à y interdire la circulation du fluide caloporteur.- Said elongated element is a tube similar to circulation tubes, interrupted so as to prevent the circulation of the heat transfer fluid there.
- Le tube constituant l'élément allongé est plus court que les tubes de circulation et n'atteint pas la boîte à fluide.- The tube constituting the elongated element is shorter than the circulation tubes and does not reach the fluid box.
- Le tube constituant l'élément allongé est séparé en deux tronçons dont l'un est lié aux intercalaires et dont l'autre traverse le collecteur et est obturé de façon à ne pas créer de fuite de fluide hors de la boîte à fluide. - The tube constituting the elongated element is separated into two sections, one of which is linked to the spacers and the other of which crosses the manifold and is closed so as not to create a leak of fluid out of the fluid box.
- Ledit élément allongé est une pièce massive qui s'étend de façon continue sensiblement sur la même longueur que les tubes de circulation.- Said elongated element is a solid piece which extends continuously substantially over the same length as the circulation tubes.
- Les tubes de circulation du sous-ensemble qui est situé du même côté de la cloison que ledit élément allongé sont au moins aussi nombreux que ceux du sous-ensemble qui est situé du côté opposé de la cloison.- The circulation tubes of the sub-assembly which is located on the same side of the partition as said elongated element are at least as numerous as those of the sub-assembly which is located on the opposite side of the partition.
L'invention a également pour objet un procédé de refroidissement, notamment du moteur thermique d'un véhicule automobile, utilisant un échangeur de chaleur tel que défini plus haut, et dans lequel le fluide caloporteur circulant dans les tubes du sous-ensemble qui est situé du même côté de la cloison que ledit élément allongé est à une température plus élevée que celui circulant dans les tubes du sous-ensemble qui est situé du côté opposé de la cloison.The invention also relates to a method of cooling, in particular the heat engine of a motor vehicle, using a heat exchanger as defined above, and in which the heat transfer fluid circulating in the tubes of the subassembly which is located on the same side of the partition as said elongated element is at a higher temperature than that circulating in the tubes of the sub-assembly which is located on the opposite side of the partition.
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 - la figure 1 est une vue partielle en coupe d'un échangeur de chaleur multiple connu; et - les figures 2 et 3 sont des vues analogues à la figure 1, relatives à deux échangeurs de chaleur selon l'invention.The characteristics and advantages of the invention will be explained in more detail in the description below, with reference to the accompanying drawings, in which - Figure 1 is a partial sectional view of a known multiple heat exchanger; and - Figures 2 and 3 are views similar to Figure 1, relating to two heat exchangers according to the invention.
La figure 1 montre partiellement un radiateur de refroidissement, notamment pour le moteur d'entraînement d'un véhicule automobile, conforme à l'enseignement de FR-A-2 634 546. Ce radiateur comprend une boîte à fluide 1 et un faisceau de tubes 2. La boîte à fluide est formée d'une pièce moulée en matière plastique 3 en forme de bac et d'une plaque ou collecteur 4 servant de couvercle à ce bac. Au moins une cloison 5 appartenant à la pièce 3 s'étend à partir du fond 6 du bac et vient en contact étanche avec le collecteur 4 par l'intermédiaire d'un joint 7. La cloison 5 sépare l'un de l'autre, à l'intérieur de la boîte à fluide, deux compartiments 8 et 9.Figure 1 partially shows a cooling radiator, in particular for the drive motor of a motor vehicle, in accordance with the teaching of FR-A-2 634 546. This radiator comprises a fluid box 1 and a bundle of tubes 2. The fluid box is formed from a molded plastic part 3 in the form of a tank and a plate or collector 4 serving as a cover for this tank. At least one partition 5 belonging to the part 3 extends from the bottom 6 of the tank and comes into tight contact with the collector 4 by means of a seal 7. The partition 5 separates one from the other , inside the fluid box, two compartments 8 and 9.
On voit sur la figure une rangée de tubes 10 allongés dans une direction sensiblement perpendiculaire au collecteur 4 et au fond 6 de la boîte à fluide, et mutuellement alignés dans la direction longitudinale de la boîte à fluide, sensiblement perpendiculaire à la cloison 5. Les tubes 10 sont maintenus uniformément écartés les uns des autres par des intercalaires 11 sous forme de bandes de tôle. Chaque bande est disposée entre deux tubes voisins et est conformée selon un parcours sinueux de façon à venir en contact alternativement avec ces deux tubes, auxquels elle est fixée par brasage. De façon habituelle, ces intercalaires servent également au transfert de chaleur entre les tubes et l'atmosphère. Par ailleurs, les tubes 10 traversent les perforations du collecteur, de façon que l'une des extrémités 12 de chacun d'eux pénètre dans la boîte à fluide, tandis que les intercalaires 11 sont à l'extérieur de celle-ci. Les tubes sont brasés au collecteur de façon étanche vis-à-vis du fluide caloporteur devant circuler dans le radiateur.We see in the figure a row of tubes 10 elongated in a direction substantially perpendicular to the manifold 4 and the bottom 6 of the fluid box, and mutually aligned in the longitudinal direction of the fluid box, substantially perpendicular to the partition 5. The tubes 10 are kept uniformly spaced from each other by spacers 11 in the form of sheet metal strips. Each strip is arranged between two neighboring tubes and is shaped along a sinuous path so as to come into contact alternately with these two tubes, to which it is fixed by brazing. Usually, these spacers are also used to transfer heat between the tubes and the atmosphere. Furthermore, the tubes 10 pass through the perforations of the manifold, so that one of the ends 12 of each of them enters the fluid box, while the spacers 11 are outside of the latter. The tubes are brazed to the collector in a sealed manner vis-à-vis the heat transfer fluid which must circulate in the radiator.
Certains des tubes 10 sont en relation avec le compartiment 8. Le fluide caloporteur peut donc s'écouler de ce compartiment dans ces tubes, et de là par exemple dans un compartiment d'une autre boîte à fluide non représentée située à l'extrémité opposée du faisceau de tubes 2. La circulation peut aussi se faire en sens inverse, c'est-à-dire des tubes 10 vers le compartiment 8. De même, un fluide caloporteur peut s'écouler du compartiment 9 à d'autres tubes 10, ou inversement.Some of the tubes 10 are in relation to the compartment 8. The heat transfer fluid can therefore flow from this compartment into these tubes, and from there, for example, into a compartment of another fluid box, not shown, situated at the opposite end. of the bundle of tubes 2. The circulation can also take place in the opposite direction, that is to say from the tubes 10 to the compartment 8. Similarly, a heat transfer fluid can flow from the compartment 9 to other tubes 10 , Or vice versa.
La pièce 3 peut comporter au moins deux cloisons telles que 5 définissant dans la boîte à fluide au moins trois compartiments tels que 8 et 9 auxquels sont associés autant de sous-ensembles de tubes du faisceau 2. Par ailleurs, ce faisceau peut comprendre d'autres rangées de tubes décalées par rapport à celle représentée dans la direction perpendicu laire au plan du dessin. Dans ce cas, un même intercalaire 11 est en contact avec une paire de tubes de chaque rangée.The part 3 can comprise at least two partitions such as 5 defining in the fluid box at least three compartments such as 8 and 9 with which there are associated as many subsets of tubes of the bundle 2. Furthermore, this bundle can include other rows of tubes offset from that shown in the direction perpendicular to the plane of the drawing. In this case, the same spacer 11 is in contact with a pair of tubes in each row.
Lorsque le fluide caloporteur circule, d'une part dans le compartiment 8 et dans le sous-ensemble de tubes associés, d'autre part dans le compartiment 9 et dans le sous-ensemble de tubes associés, à des températures qui diffèrent de plusieurs dizaines de degrés C, une dilatation différentielle apparaît entre les deux sous-ensembles. Cependant, le collecteur 4, qui est lié de façon rigide, en des points rapprochés, aux deux tubes 10a et 10b les plus voisins de la cloison 5 et communiquant respectivement avec les compartiments 8 et 9, tend à s'opposer à la dilatation différentielle de ces deux tubes et crée des contraintes mécaniques dans ceux-ci.When the heat transfer fluid circulates, on the one hand in compartment 8 and in the associated tube sub-assembly, on the other hand in compartment 9 and in the associated tube sub-assembly, at temperatures which differ by several tens of degrees C, a differential expansion appears between the two subsets. However, the manifold 4, which is rigidly connected, at close points, to the two tubes 10a and 10b closest to the partition 5 and communicating with the compartments 8 and 9 respectively, tends to oppose the differential expansion of these two tubes and creates mechanical stresses in them.
La figure 2, dans laquelle les mêmes numéros de référence qu'à la figure 1 sont utilisés pour désigner des éléments identiques ou analogues, montre une solution apportée par l'invention à ce problème. Le tube 10b est remplacé par un tube 10c qui diffère de celui-ci par la suppression de sa région d'extrémité traversant le collecteur 4. La perforation correspondante de celui-ci est également supprimée, ou est obturée par un moyen approprié. Le tube 10c n'est pas en contact avec le collecteur 4 et le fluide n'y circule pas, de sorte qu'il n'est pas affecté par les problèmes de dilatation. Le tube 10d, qui est parmi ceux débouchant dans le compartiment 9 le plus proche du tube 10a, est deux fois plus éloigné de celui-ci que l'était le tube 10b de la figure 1, ce qui limite les effets néfastes de leur liaison mutuelle par le collecteur.FIG. 2, in which the same reference numbers as in FIG. 1 are used to designate identical or analogous elements, shows a solution provided by the invention to this problem. The tube 10b is replaced by a tube 10c which differs from the latter by the elimination of its end region passing through the collector 4. The corresponding perforation of the latter is also eliminated, or is closed by an appropriate means. The tube 10c is not in contact with the manifold 4 and the fluid does not circulate there, so that it is not affected by the problems of expansion. The tube 10d, which is among those opening into the compartment 9 closest to the tube 10a, is twice as far from the latter as was the tube 10b in FIG. 1, which limits the harmful effects of their connection mutual by the collector.
Au lieu de supprimer la région d'extrémité du tube 10b pour obtenir la structure de la figure 2, on peut tout aussi bien la séparer, comme par un trait de scie, du reste du tube.Instead of removing the end region of the tube 10b to obtain the structure of FIG. 2, it can just as easily be separated, as by a saw cut, from the rest of the tube.
Afin d'éviter une fuite de fluide hors du compartiment 9 par cette région d'extrémité sectionnée, il faut l'obturer de façon étanche, soit en y introduisant un bouchon, soit en l'écrasant. In order to avoid leakage of fluid from compartment 9 through this sectioned end region, it must be sealed off, either by introducing a plug therein, or by crushing it.
A la figure 3, les mêmes numéros de référence qu'aux figures précédentes sont de nouveau utilisés. Le tube 10b de la figure 1 est ici remplacé par une tige pleine 13 qui s'étend sur la même longueur que les tubes 10, et traverse par conséquent le collecteur 4 qui n'a ainsi pas besoin d'être modifié. Du fait que la tige 13 n'est pas en contact avec le fluide caloporteur sur la majeure partie de sa longueur, et qu'elle est refroidie par l'air traversant le faisceau 2, par l'intermédiaire des intercalaires 11, elle ne se dilate pratiquement pas. En raison de sa liaison mécanique avec les tubes voisins 10a et 10b, elle subit un effort de traction que sa section importante lui permet de supporter sans dommages. Les tubes 10a et 10d quant à eux subissent un effort de compression qui ne risque pas d'entraîner une rupture par fatigue.In FIG. 3, the same reference numbers as in the preceding figures are again used. The tube 10b of FIG. 1 is here replaced by a solid rod 13 which extends over the same length as the tubes 10, and consequently crosses the manifold 4 which thus does not need to be modified. Due to the fact that the rod 13 is not in contact with the heat transfer fluid over most of its length, and that it is cooled by the air passing through the bundle 2, by means of the spacers 11, it does not hardly expands. Due to its mechanical connection with the neighboring tubes 10a and 10b, it undergoes a tensile force which its large section allows it to support without damage. The tubes 10a and 10d, for their part, undergo a compressive force which is not likely to cause rupture by fatigue.
De préférence, la suppression d'un tube de circulation de fluide caloporteur, entraînée par l'invention, se fait dans celui des sous-ensembles concernés dans lequel ils seraient autrement les plus nombreux, de façon à minimiser l'effet résultant sur la circulation du fluide. Il en résulte que le sous-ensemble en question, qui correspond généralement à la température la plus élevée, comporte au moins autant de tubes de circulation que l'autre sous-ensemble. Preferably, the removal of a heat transfer fluid circulation tube, driven by the invention, is done in that of the sub-assemblies concerned in which they would otherwise be the most numerous, so as to minimize the resulting effect on the circulation. fluid. As a result, the sub-assembly in question, which generally corresponds to the highest temperature, comprises at least as many circulation tubes as the other sub-assembly.
