Description

Domaine de l'inventionField of the invention

La présente invention concerne un échangeur de chaleur, par exemple un échangeur de chaleur destiné à un véhicule automobile. Plus précisément, l'invention concerne un échangeur de chaleur permettant l'échange entre un premier fluide et un deuxième fluide, dans lequel le premier fluide est par exemple un fluide gazeux tel que de l'air et le deuxième fluide liquide tel que de l'eau. L'échangeur de chaleur, selon la présente invention, est particulièrement adapté afin d'être utilisé pour le refroidissement de l'air de suralimentation. En particulier, la présente invention se rapporte à un échangeur de chaleur conforme au préambule de la revendication 1 et tel que divulgué par le document WO 2007/048603A2 .The present invention relates to a heat exchanger, for example a heat exchanger for a motor vehicle. More specifically, the invention relates to a heat exchanger for the exchange between a first fluid and a second fluid, wherein the first fluid is for example a gaseous fluid such as air and the second liquid fluid such as 'water. The heat exchanger according to the present invention is particularly suitable for use in cooling the charge air. In particular, the present invention relates to a heat exchanger according to the preamble of claim 1 and as disclosed by the document WO 2007 / 048603A2 .

Etat de la techniqueState of the art

De nos jours, les moteurs à combustion des véhicules automobiles sont fréquemment alimentés en air comprimé afin d'améliorer les performances de ces moteurs. Cet air comprimé est souvent désigné à l'aide du terme « air de suralimentation ». L'air comprimé est obtenu en utilisant un compresseur entraîné par les gaz d'échappement. Par conséquent, la compression de l'air a pour effet d'échauffer l'air. Ainsi, il s'avère nécessaire de refroidir l'air comprimé avant son introduction à l'intérieur du moteur, afin d'abaisser la température de l'air avant son introduction dans un cylindre du moteur.Nowadays, combustion engines of motor vehicles are frequently supplied with compressed air to improve the performance of these engines. This compressed air is often referred to as "boost air". Compressed air is obtained using a compressor driven by the exhaust gas. Therefore, the compression of the air has the effect of heating the air. Thus, it is necessary to cool the compressed air before its introduction into the engine, to lower the temperature of the air before its introduction into a cylinder of the engine.

Pour refroidir l'air comprimé, il est connu d'utiliser un échangeur de chaleur comprenant un faisceau d'échange de chaleur constitué d'un assemblage de plaques, positionnées les unes sur les autres et formant en combinaison un conduit permettant de guider un fluide tel qu'un liquide, d'une entrée vers une sortie. Afin d'améliorer l'échange de chaleur, l'assemblage des plaques est complété grâce à des éléments intercalaires ondulés.To cool the compressed air, it is known to use a heat exchanger comprising a heat exchange bundle consisting of an assembly of plates, positioned one on the other and forming in combination a conduit for guiding a fluid. such as a liquid, from an inlet to an outlet. In order to improve the heat exchange, the plate assembly is completed by means of corrugated spacer elements.

Le faisceau d'échange de chaleur est positionné à l'intérieur d'un carter ou boîtier. Ce boîtier est pourvu d'une entrée et d'une sortie pour le deuxième fluide à refroidir, tel que l'air et est adapté pour guider l'air d'une entrée vers une sortie. Le boîtier a la fonction d'une boîte collectrice enveloppant ledit faisceau de chaleur et permettant l'admission et la régulation de l'air de suralimentation. Un tel boîtier est par exemple moulé dans une matière telle que l'aluminium ou le plastique.The heat exchange bundle is positioned within a housing or housing. This housing is provided with an inlet and an outlet for the second fluid to be cooled, such as air, and is adapted to guide air from an inlet to an outlet. The housing has the function of a collector box enveloping said heat beam and allowing admission and regulation of the charge air. Such a housing is for example molded in a material such as aluminum or plastic.

En pratique, les parois des boîtiers sont relativement fines et relativement souples. Ainsi, lors de l'utilisation des boîtiers, le volume desdits boîtiers peut augmenter en fonction de l'augmentation de la pression et de la température à l'intérieur des boîtiers.In practice, the walls of the housings are relatively thin and relatively flexible. Thus, when using the housings, the volume of said housings can increase as a function of the increase in pressure and temperature inside the housings.

Le boîtier d'un échangeur de chaleur, selon l'art antérieur, est pourvu d'une ouverture permettant d'introduire le faisceau d'échange de chaleur à l'intérieur du boîtier. Pour ce type d'application, le faisceau d'échange de chaleur est, en principe, connecté à un élément de fermeture tel qu'un capot. Le capot permet de connecter l'assemblage des plaques et des éléments intercalaires ondulés de l'échangeur de chaleur et de fixer l'ensemble contre ladite plaque de connexion. Le capot est pourvu de conduits permettant l'introduction et l'émission du fluide liquide, tel qu'un liquide, à l'intérieur de l'échangeur de chaleur. Le capot fixé au faisceau d'échange réalise une fonction de fermeture de l'ouverture permettant l'introduction de l'échangeur de chaleur. Ainsi, dans un premier temps, le faisceau d'échange de chaleur est enveloppé ou entouré des parois du boîtier et, dans un deuxième temps, entouré du capot.The housing of a heat exchanger, according to the prior art, is provided with an opening for introducing the heat exchange bundle inside the housing. For this type of application, the heat exchange bundle is, in principle, connected to a closure element such as a hood. The cover allows to connect the assembly of the corrugated plates and corrugated elements of the heat exchanger and to fix the assembly against said connection plate. The hood is provided with conduits allowing the introduction and the emission of the liquid fluid, such as a liquid, inside the heat exchanger. The cap attached to the exchange beam performs a function of closing the opening for the introduction of the heat exchanger. Thus, in a first step, the heat exchange bundle is wrapped or surrounded by the walls of the housing and, in a second step, surrounded by the hood.

Dans sa position d'utilisation, le capot, auquel le faisceau d'échange de chaleur est fixé, se trouve en principe positionné de façon essentiellement horizontale, au-dessus dudit faisceau d'échange de chaleur. En d'autres termes, le faisceau d'échange de chaleur est suspendu au capot.In its position of use, the hood, to which the heat exchange bundle is attached, is in principle positioned substantially horizontally, above said heat exchange bundle. In other words, the heat exchange bundle is suspended from the hood.

Les échangeurs de chaleur connus de l'art antérieur présentent plusieurs inconvénients. Dans un premier temps, la connexion entre le boîtier et le capot est très fragile et doit résister à la haute pression et aux hautes températures présentes à l'intérieur de l'échangeur de chaleur. De plus, les parois du boîtier peuvent, lors de l'utilisation normale de l'échangeur de chaleur, se déformer sous la pression de l'air chaud présent à l'intérieur dudit échangeur de chaleur. Cette déformation, constante lors de l'utilisation de l'échangeur de chaleur, peut provoquer une usure prématurée du matériau utilisé lors de la fabrication du boîtier. Ainsi, la fiabilité du boîtier peut être altérée.Heat exchangers known from the prior art have several disadvantages. At first, the connection between the housing and the hood is very fragile and must withstand the high pressure and high temperatures present inside the heat exchanger. In addition, the walls of the housing may, during normal use of the heat exchanger, deform under the pressure of the hot air present inside said heat exchanger. This deformation, constant during use of the heat exchanger, can cause premature wear of the material used in the manufacture of the housing. Thus, the reliability of the housing can be altered.

Dans la mesure où le faisceau d'échange de chaleur est suspendu au capot, le faisceau d'échange de chaleur peut présenter des mouvements pendulaires sous l'influence des vibrations imposées par le fonctionnement du moteur du véhicule avec lequel l'échangeur de chaleur est utilisé. La répétition de ces mouvements pendulaires, tout particulièrement en présence d'un effet de résonnance, peut avoir une influence néfaste sur la fiabilité de l'échangeur de chaleur.Since the heat exchange bundle is suspended from the hood, the heat exchange bundle can exhibit pendular movements under the influence of the vibrations imposed by the operation of the engine of the vehicle with which the heat exchanger is used. The repetition of these pendular movements, especially in the presence of a resonance effect, can have a detrimental influence on the reliability of the heat exchanger.

De nos jours, le volume destiné aux échangeurs de chaleur et à leurs composants au sein des véhicules automobiles a tendance à être réduit au profit de l'intégration d'autres dispositifs nécessaires au fonctionnement desdits véhicules automobiles. Par ailleurs, il est important de réduire le poids de tous les composants d'un véhicule, y compris celui de l'échangeur de chaleur. Il est donc important de mettre au point des échangeurs de chaleur compacts permettant une construction relativement légère.Nowadays, the volume intended for heat exchangers and their components within motor vehicles tends to be reduced in favor of the integration of other devices necessary for the operation of said motor vehicles. In addition, it is important to reduce the weight of all components of a vehicle, including that of the heat exchanger. It is therefore important to develop compact heat exchangers for relatively light construction.

Objet de l'inventionObject of the invention

L'échangeur de chaleur selon la présente invention vise à remédier aux inconvénients des échangeurs de chaleurs, tels que divulgués dans l'état de la technique, en proposant une nouvelle conception quant à la fixation d'un faisceau d'échange de chaleur à l'intérieur du boîtier d'un échangeur de chaleur.The heat exchanger according to the present invention aims to overcome the disadvantages of heat exchangers, as disclosed in the state of the art, by proposing a new design for the attachment of a heat exchange beam to the heat exchanger. inside the housing of a heat exchanger.

A cet effet, la présente invention concerne un échangeur de chaleur comprenant un boîtier adapté pour envelopper un faisceau d'échange de chaleur, ledit boîtier étant pourvu d'une ouverture permettant de recevoir ledit faisceau d'échange de chaleur à l'intérieur dudit boîtier et d'un faisceau d'échange de chaleur, ledit faisceau d'échange de chaleur comprenant une première extrémité adaptée pour obturer l'ouverture du boîtier lorsque le faisceau d'échange de chaleur est inséré à l'intérieur dudit boîtier, caractérisé en ce que une deuxième extrémité du faisceau d'échange de chaleur opposée à ladite première extrémité est pourvue d'au moins un moyen de fixation se présentant sous la forme d'une cheville, pour fixer ladite deuxième extrémité du faisceau d'échange de chaleur à la paroi du boîtier.For this purpose, the present invention relates to a heat exchanger comprising a housing adapted to envelop a heat exchange bundle, said housing being provided with an opening for receiving said heat exchange bundle within said housing and a heat exchange bundle, said heat exchange bundle including a first end adapted to close the opening of the housing when the heat exchange bundle is inserted inside said housing, characterized in that a second end of the heat exchange bundle opposite said first end is provided with at least one fastening means which is the shape of a peg, for fixing said second end of the heat exchange bundle to the wall of the housing.

Description détaillée des modes de réalisationDetailed Description of the Embodiments

La figure 1 montre une vue en perspective d'un mode de réalisation d'un échangeur de chaleur 1 selon la présente invention. Une partie de l'extérieur de l'échangeur de chaleur 1 a été retirée afin de montrer l'intérieur dudit échangeur de chaleur.The figure 1 shows a perspective view of an embodiment of a heat exchanger 1 according to the present invention. Part of the outside of the heat exchanger 1 has been removed to show the inside of said heat exchanger.

L'échangeur de chaleur tel que montré sur la figure 1 est particulièrement adapté pour une utilisation dans l'industrie automobile afin de refroidir l'air de suralimentation (RAS) d'un moteur thermique. L'échangeur de chaleur 1 permet de refroidir l'air de suralimentation par échange thermique avec un premier fluide, comme l'air extérieur, ou un liquide comme, par exemple, l'eau de refroidissement d'un moteur, formant ainsi un échangeur de type air/air ou liquide/air.The heat exchanger as shown on the figure 1 is particularly suitable for use in the automotive industry to cool the charge air (RAS) of a heat engine. The heat exchanger 1 makes it possible to cool the charge air by heat exchange with a first fluid, such as outside air, or a liquid such as, for example, the cooling water of an engine, thus forming an exchanger air / air or liquid / air type.

Dans un premier temps, l'échangeur de chaleur 1 comprend un collecteur d'admission 2, souvent désigné par l'homme du métier sous la dénomination anglaise « intake manifold ». Le collecteur d'admission 2 est fixé à la culasse de la chambre de combustion du moteur, c'est-à-dire à l'entrée du cylindre. En fonction du régime du moteur, l'air peut être refroidi, totalement, partiellement ou l'air peut ne pas être refroidi. Le collecteur d'admission 2 est connecté à un boîtier ou boîtier 3. Ce boîtier 3 forme une enveloppe pour un faisceau d'échange de chaleur 4 se trouvant à l'intérieur dudit boîtier 3.In a first step, the heat exchanger 1 comprises an intake manifold 2, often designated by the skilled person under the name "intake manifold". The intake manifold 2 is fixed to the cylinder head of the combustion chamber of the engine, that is to say at the inlet of the cylinder. Depending on the engine speed, the air can be cooled, totally, partially or the air can not be cooled. The intake manifold 2 is connected to a housing or housing 3. This housing 3 forms an envelope for a heat exchange bundle 4 located inside said housing 3.

Le faisceau d'échange de chaleur 4, selon la présente invention, est positionné à l'intérieur d'un boîtier 3. Ce boîtier 3 est pourvu d'une entrée et d'une sortie pour un premier fluide gazeux et est adapté pour guider ledit premier fluide d'une entrée vers une sortie.The heat exchange bundle 4, according to the present invention, is positioned inside a housing 3. This housing 3 is provided with an inlet and an outlet for a first gaseous fluid and is adapted to guide said first fluid from an inlet to an outlet.

L'échangeur de chaleur 1 selon la présente invention comprend un faisceau d'échange de chaleur 4 constitué d'un assemblage de plaques, positionnées les unes sur les autres et formant en combinaison un conduit permettant de guider un deuxième fluide liquide, utilisé pour refroidir le premier fluide gazeux, d'une entrée vers une sortie. Afin d'améliorer l'échange de chaleur, l'assemblage des plaques est complété grâce à des éléments intercalaires ondulés.The heat exchanger 1 according to the present invention comprises a heat exchange bundle 4 consisting of an assembly of plates, positioned one on the other and forming in combination a conduit for guiding a second liquid fluid, used to cool the first gaseous fluid, from an inlet to an outlet. In order to improve the heat exchange, the plate assembly is completed by means of corrugated spacer elements.

Dans un fonctionnement connu, un premier fluide tel que l'air passe à l'extérieur du faisceau d'échange de chaleur 4 et un deuxième fluide, tel que, par exemple, l'eau du circuit de refroidissement, circule à l'intérieur du faisceau d'échange de chaleur 4 et permet ainsi à l'air d'être refroidi.In a known operation, a first fluid such as air passes outside the heat exchange bundle 4 and a second fluid, such as, for example, water cooling circuit circulates inside heat exchange bundle 4 and thus allows the air to be cooled.

Le faisceau d'échange de chaleur 4 est formé d'un assemblage de plaques embouties, encore appelées « demi-lames ». Cependant, l'invention s'applique également à d'autres types de faisceaux, et notamment à des faisceaux comportant des tubes et des ailettes. Le faisceau d'échange de chaleur 4, tel que montré sur la figure 2, est formé d'un empilement de plaques embouties disposées par paires, réalisées à l'identique. Seules les deux plaques d'extrémité formant l'extrémité supérieure et l'extrémité inférieure du faisceau d'échange de chaleur 4, comme montré sur la figure 1, sont de forme différente par rapport aux plaques embouties empilées.The heat exchange bundle 4 is formed of an assembly of stamped plates, also called "half-blades". However, the invention also applies to other types of beams, including beams having tubes and fins. The heat exchange bundle 4, as shown on the figure 2 , is formed of a stack of stamped plates arranged in pairs, made identically. Only the two end plates forming the upper end and the lower end of the heat exchange bundle 4, as shown in FIG. figure 1 , are of different shape compared to the stamped plates stacked.

Chaque plaque emboutie présente une forme rectangulaire et comporte une paroi de fond sensiblement plane limitée par un rebord périphérique de forme rectangulaire, qui est surélevé par rapport à la paroi de fond pour former une cuvette peu profonde. Chaque paire de plaques embouties délimite une chambre. L'utilisation d'une plaque de ce type est connue de l'homme du métier.Each stamped plate has a rectangular shape and has a substantially planar bottom wall bounded by a rectangular-shaped peripheral rim, which is raised relative to the bottom wall to form a shallow bowl. Each pair of stamped plates delimits a chamber. The use of a plate of this type is known to those skilled in the art.

Les plaques embouties forment le faisceau d'échange de chaleur 4, disposées par paires. Le bossage respectif d'une plaque emboutie appartenant à une paire est en communication avec le bossage respectif d'une plaque emboutie adjacente appartenant à une partie des plaques embouties voisines.The stamped plates form the heat exchange bundle 4, arranged in pairs. The respective boss of a pressed plate belonging to a pair is in communication with the respective boss of an adjacent stamped plate belonging to a portion of the neighboring stamped plates.

Le faisceau d'échange de chaleur 4 comprend des éléments intercalaires ondulés 5, comme montré sur la figure 2, disposés entre des paires de plaques embouties adjacentes. Les différentes plaques embouties et les éléments intercalaires ondulés 5 sont, selon une technique connue, assemblées grâce à un processus de brasage. Après assemblage, le faisceau d'échange de chaleur 4 délimite des premiers canaux pour le gaz à refroidir, dans lesquels sont présents les éléments intercalaires ondulés 5, et des seconds canaux pour la circulation du liquide de refroidissement obtenu en utilisant des plaques.The heat exchange bundle 4 comprises corrugated spacer elements 5, as shown in FIG. figure 2 , disposed between pairs of adjacent stamped plates. The various stamped plates and corrugated intermediate elements 5 are, according to a known technique, assembled through a brazing process. After assembly, the heat exchange bundle 4 defines first channels for the gas to be cooled, in which the corrugated spacer elements 5 are present, and second channels for the circulation of the cooling liquid obtained using plates.

L'ensemble des constituants du faisceau d'échange de chaleur 4, les plaques embouties, les éléments intercalaires ondulés 5, les collecteurs d'admission et turbuleurs d'entrée et de sortie du liquide de refroidissement sont avantageusement réalisés dans un alliage d'aluminium, assemblés entre eux et brasés en une seule opération dans un four de brasage.The set of constituents of the heat exchange bundle 4, the stamped plates, the corrugated spacer elements 5, the inlet manifolds and turbulators for entering and leaving the cooling liquid are advantageously made of an aluminum alloy , assembled together and brazed in a single operation in a brazing furnace.

Comme montré sur la figure 1, la partie supérieure du faisceau d'échange de chaleur 4 est fixée sur un élément de fermeture 6 tel qu'une plaque ou un capot 6. Le capot 6 réalise plusieurs fonctions. Une des fonctions consiste à permettre au capot une entrée et une sortie du liquide de refroidissement au moyen de tubulures disposées sur le capot 6. Par ailleurs, le capot 6 forme l'élément de fermeture du boîtier 3. Ainsi, lorsque l'échangeur de chaleur 1 est assemblé, le faisceau d'échange de chaleur 4 est enveloppé, d'une part par des parois formées par le boîtier 3, et d'autre part par le capot 6.As shown on the figure 1 , the upper part of the heat exchange bundle 4 is fixed on a closure element 6 such as a plate or a cover 6. The cover 6 performs several functions. One of the functions is to allow the hood inlet and outlet of the coolant by means of pipes disposed on the cover 6. Moreover, the cover 6 forms the closing element of the housing 3. Thus, when the heat exchanger heat 1 is assembled, the heat exchange bundle 4 is wrapped, on the one hand by walls formed by the housing 3, and on the other hand by the cover 6.

L'échangeur de chaleur 1 selon la présente invention est pourvu d'éléments de fixation 21, 22 et 23 qui sont fixés à l'extrémité inférieure du faisceau d'échange de chaleur 4. Les éléments de fixation 21, 22 et 23 sont adaptés pour traverser la paroi du boîtier 3 et être fixés à ladite paroi du boîtier 3, par le biais de tout moyen adapté.The heat exchanger 1 according to the present invention is provided with fastening elements 21, 22 and 23 which are attached to the lower end of the heat exchange bundle 4. The fastening elements 21, 22 and 23 are adapted to cross the wall of the housing 3 and be fixed to said wall of the housing 3, by means of any suitable means.

Lorsque les éléments de fixation 21, 22 et 23 sont fixés sur la paroi du boîtier 3, plusieurs effets techniques sont réalisés. Notamment, la rigidité de l'échangeur de chaleur 1 augmente. De plus, l'ensemble des éléments de fixation 21, 22 et 23 forme une structure homogène et unie lorsque le côté inférieur du faisceau d'échange de chaleur 4 est fixé aux parois du boîtier 3.When the fastening elements 21, 22 and 23 are fixed on the wall of the housing 3, several technical effects are realized. In particular, the rigidity of the heat exchanger 1 increases. In addition, all the fastening elements 21, 22 and 23 form a homogeneous and uniform structure when the lower side of the heat exchange bundle 4 is fixed to the walls of the casing 3.

Ainsi, lorsque le faisceau d'échange de chaleur 4 est fixé sur les parois du boîtier 3, lesdites parois du boîtier 3 ne peuvent plus subir de déformation résultant de l'action de l'air chaud et sous pression présent à l'intérieur dudit boîtier 3. La déformation est donc limitée lors de l'utilisation normale d'un échangeur de chaleur 1 selon la présente invention. Par ailleurs, lorsque le côté inférieur du faisceau d'échange de chaleur 4 est fixé sur les parois du boîtier 3, ce faisceau d'échange de chaleur 4 ne peut plus effectuer de mouvement pendulaire. En d'autres termes, l'effet d'usure néfaste engendré par les mouvements pendulaires est donc supprimé.Thus, when the heat exchange bundle 4 is fixed on the walls of the housing 3, said walls of the housing 3 can no longer undergo deformation resulting from the action of hot air and pressure present inside said 3. The deformation is therefore limited during the normal use of a heat exchanger 1 according to the present invention. Furthermore, when the lower side of the heat exchange bundle 4 is fixed on the walls of the housing 3, this heat exchange bundle 4 can no longer perform pendulum movement. In other words, the harmful wear effect caused by the pendular movements is therefore eliminated.

La figure 2 représente en détail un premier mode de réalisation de l'élément de fixation 21. La figure 2 montre que les parois 31 du boîtier 3 comportent une rupture permettant de laisser passer l'élément de fixation 21. L'élément de fixation 21 est fixé à l'extrémité inférieure d'un faisceau d'échange de chaleur grâce à un processus de brasage. Cela signifie que pendant l'assemblage du faisceau d'échange de chaleur 4, une seule opération, réalisée dans un four de brasage, permet d'assembler un faisceau d'échange de chaleur 4 et de fixer les éléments de fixation 21, 22 et 23 à l'extrémité inférieure du faisceau d'échange de chaleur.The figure 2 shows in detail a first embodiment of the fastener 21. figure 2 shows that the walls 31 of the housing 3 comprise a break allowing the fixing element 21 to pass through. The fastening element 21 is fastened to the lower end of a heat exchange bundle by means of a soldering process . This means that during the assembly of the heat exchange bundle 4, a single operation, carried out in a brazing furnace, makes it possible to assemble a heat exchange bundle 4 and to fix the fastening elements 21, 22 and 23 at the lower end of the heat exchange bundle.

L'élément de fixation 21 peut, par exemple, être fixé sur les parois 31 du boîtier 3 à l'aide d'un écrou (non montré).The fixing element 21 may, for example, be fixed on the walls 31 of the housing 3 by means of a nut (not shown).

La figure 3 montre un deuxième mode de réalisation de la fixation d'un élément de fixation 41. Selon ce mode de réalisation, l'élément de fixation 41 est fixé à l'extrémité inférieure du faisceau d'échange de chaleur 4 grâce à un moyen d'assemblage élastique ou selon la dénomination anglaise « snap-fit ».The figure 3 shows a second embodiment of the fixing of a fastening element 41. According to this embodiment, the fastening element 41 is attached to the lower end of the heat exchange bundle 4 through an elastic assembly means or according to the English name "snap-fit".

La figure 4 représente, de façon schématique, un troisième mode de réalisation de la fixation d'un élément de fixation 51 sur l'extrémité inférieure d'un faisceau d'échange de chaleur 4. L'élément de fixation 51 est réalisé en matière plastique pouvant se déformer sous l'influence d'une source de chaleur. Comme montré sur la figure 4, lorsque l'élément de fixation 51 a traversé la paroi 31 du boîtier 3 montré sur la figure 1, une certaine quantité de chaleur, combiné à une quantité de pression, peut être utilisée pour déformer l'élément de fixation 51 et fixer ainsi la partie inférieure du faisceau de l'échangeur de chaleur 4 sur la paroi 31 du boîtier 3.The figure 4 schematically shows a third embodiment of the fixing of a fastening element 51 on the lower end of a heat exchange bundle 4. The fastening element 51 is made of plastic material which can be deform under the influence of a heat source. As shown on the figure 4 when the fixing element 51 has passed through the wall 31 of the housing 3 shown on the figure 1 a quantity of heat, combined with a quantity of pressure, can be used to deform the fixing element 51 and thus fix the lower part of the heat exchanger beam 4 on the wall 31 of the housing 3.

Un autre mode de réalisation d'un élément de fixation 61 est montré sur la figure 6. Le premier élément « femelle » peut être fixé ou assemblé, par exemple à l'aide d'un processus de brasage, sur l'extrémité inférieure du faisceau de l'échangeur de chaleur 4. Après assemblage, cet élément de fixation 61 peut être fixé sur la paroi 31 du boîtier 3 grâce à une vis 62 formant l'élément « mâle » de la fixation 25.Another embodiment of a fastener 61 is shown on the figure 6 . The first "female" element can be fixed or assembled, for example by means of a brazing process, on the lower end of the heat exchanger bundle 4. After assembly, this fastening element 61 can be fixed on the wall 31 of the housing 3 by means of a screw 62 forming the "male" element of the fastener 25.

Lors de l'utilisation de l'échangeur de chaleur 1 selon la présente invention, il est important que l'enveloppe située autour du faisceau d'échange de chaleur 4 soit étanche. Ainsi, les fixations de la partie inférieure du faisceau d'échange de chaleur 4, sur la paroi 31 du boîtier 3, doivent être réalisées avec soin. Afin d'assurer l'étanchéité du passage des éléments de fixation 21, 22, 23, 41, 51 et 61, il convient de prévoir des éléments d'étanchéité, tels que des anneaux d'étanchéité.When using the heat exchanger 1 according to the present invention, it is important that the envelope located around the heat exchange bundle 4 is sealed. Thus, the fasteners of the lower part of the heat exchange bundle 4, on the wall 31 of the housing 3, must be made carefully. In order to seal the passage of the fastening elements 21, 22, 23, 41, 51 and 61, it is necessary to provide sealing elements, such as sealing rings.

Au sein des exemples de modes de réalisation décrits ci-dessus, il est indiqué que les éléments de fixation 21, 22, 23, 61 peuvent être fixés à l'extrémité inférieure du faisceau d'échange de chaleur 4 grâce à un processus de brasage. Tout autre procédé de fixation d'éléments de fixation peut être envisagé, par exemple, grâce à l'utilisation d'un moyen adhésif adapté.Within the exemplary embodiments described above, it is indicated that the fastening elements 21, 22, 23, 61 can be attached to the lower end of the heat exchange bundle 4 by means of a soldering process . Any other method of attaching fasteners may be envisioned, for example, through the use of a suitable adhesive means.

La figure 5 montre la fixation du faisceau d'échange de chaleur aux parois du boîtier de l'échangeur de chaleur en utilisant un élément de fixation réalisé en matière plastique, après l'application d'une certaine quantité de chaleur permettant de modifier la forme dudit élément de fixation.The figure 5 shows the attachment of the heat exchange bundle to the walls of the heat exchanger housing by using a fastener made of plastic, after the application of a certain amount of heat to modify the shape of said element of fixation.

La figure 6 représente la fixation du faisceau d'échange de chaleur aux parois du boîtier de l'échangeur de chaleur en utilisant une fixation comportant des éléments de fixation « mâle » et « femelle ».The figure 6 represents the attachment of the heat exchange bundle to the walls of the heat exchanger housing using a fastener having "male" and "female" fasteners.
