Description

L'invention concerne une boîte collectrice pour échangeur thermique, en particulier pour véhicule automobile. Une telle boîte collectrice ayant les caractéristiques du préambule de la revendication 1 est connue de WO2006/082084 . L'invention concerne aussi un échangeur thermique correspondant. Un tel échangeur thermique est par exemple utilisé dans un véhicule automobile, notamment en tant que radiateur de système de refroidissement, ou dans des applications à haute pression par exemple comme condenseur d'un système de climatisation.The invention relates to a manifold for a heat exchanger, in particular for a motor vehicle. Such a collector box having the characteristics of the preamble of claim 1 is known from WO2006 / 082084 . The invention also relates to a corresponding heat exchanger. Such a heat exchanger is for example used in a motor vehicle, in particular as a cooling system radiator, or in high pressure applications, for example as a condenser of an air conditioning system.

Généralement, un tel échangeur thermique comprend un faisceau de tubes et au moins une boîte collectrice. Cette boîte collectrice est configurée pour recevoir les extrémités des tubes de l'échangeur thermique.Generally, such a heat exchanger comprises a bundle of tubes and at least one header box. This header box is configured to receive the ends of the tubes of the heat exchanger.

À cet effet, la boîte collectrice comporte généralement un collecteur par exemple sous forme de plaque collectrice. La boîte collectrice comporte généralement également un couvercle venant se fixer sur la plaque collectrice pour fermer la boîte collectrice.For this purpose, the collector box generally comprises a collector, for example in the form of a collector plate. The collector box generally also includes a cover which is fixed on the collector plate to close the collector box.

La plaque collectrice permet de distribuer le fluide vers les tubes d'échange thermique ou de collecter le fluide provenant de ces tubes d'échange thermique. La plaque collectrice est généralement en aluminium et peut être réalisée par exemple par estampage.The collector plate makes it possible to distribute the fluid to the heat exchange tubes or to collect the fluid coming from these heat exchange tubes. The collector plate is generally made of aluminum and can be produced for example by stamping.

La plaque collectrice présente un fond généralement plat.The collector plate has a generally flat bottom.

Toutefois, dans les applications destinées à résister à la pression, il est connu que le collecteur présente un fond au moins partiellement arrondi pour tenir la pression.Par ailleurs, la plaque collectrice à fond plat ou à fond arrondi est habituellement munie de collets entourant des ouvertures traversées par les extrémités des tubes du faisceau de l'échangeur thermique.However, in applications intended to withstand pressure, it is known that the manifold has an at least partially rounded bottom to withstand the pressure. Furthermore, the collector plate with a flat bottom or a rounded bottom is usually provided with collars surrounding the collars. openings crossed by the ends of the tubes of the heat exchanger bundle.

Les ouvertures telles que des fentes sont réalisées dans la plaque collectrice pour introduire les tubes, par exemple avec un enlèvement de matière ou au contraire sans enlèvement de matière. Dans ce dernier cas, la matière est poussée par l'outillage vers l'intérieur du volume défini par la boîte collectrice, créant ainsi un collet autour de l'ouverture pour l'introduction du tube. On parle de collets standards.The openings such as slits are made in the collector plate to introduce the tubes, for example with removal of material or, on the contrary, without removal of material. In the latter case, the material is pushed by the tool towards the interior of the volume defined by the collector box, thus creating a collar around the opening for the introduction of the tube. We are talking about standard collars.

Les collets permettent d'avoir un bon contact entre le tube et l'ouverture dans la plaque collectrice et d'obtenir une bonne qualité de brasage dans le cas des échangeurs brasés, par exemple tout en aluminium.The collars allow good contact between the tube and the opening in the collector plate and obtain a good brazing quality in the case of brazed exchangers, for example all aluminum.

Les tubes sont généralement insérés dans l'ouverture dans le même sens que l'outillage pour réaliser les collets autour des ouvertures. Les tubes insérés s'étendent généralement en partie à l'intérieur la boîte collectrice pour garantir un brasage correct et un assemblage solide et étanche. Selon certaines solutions, les tubes dépassent dans le volume formant réservoir du fluide de près de la moitié du volume de la boîte collectrice.The tubes are generally inserted into the opening in the same direction as the tooling to make the collars around the openings. The inserted tubes generally extend partly inside the header box to ensure proper brazing and a strong, tight assembly. According to some solutions, the tubes protrude into the volume forming the fluid reservoir by nearly half the volume of the manifold.

Cependant, le dépassement des tubes dans le volume défini par le volume intérieur de la boîte collectrice formant réservoir du fluide, crée une chute de pression interne sur le circuit de fluide. Cette baisse de pression interne nécessite d'augmenter la puissance de pompage pour conserver un certain débit de fluide.However, the protrusion of the tubes in the volume defined by the interior volume of the manifold box forming the fluid reservoir, creates an internal pressure drop on the fluid circuit. This drop in internal pressure requires increasing the pumping power to maintain a certain flow of fluid.

Selon une solution connue, une boîte collectrice à fond plat peut présenter des collets dits inversés c'est-à-dire réalisés selon le sens opposé au sens d'insertion d'un tube d'échange thermique. Les collets présentent alors une forme évasée orientée vers l'opposé du volume défini par la boîte collectrice. Toutefois, de tels collets inversés présentent un faible évasement, autrement dit les collets inversés connus définissent un cône d'entrée faible pour l'insertion des tubes d'échange thermique. Le cône d'entrée peut donc ne pas être suffisant pour permettre une insertion simple des tubes d'échange thermique, et les solutions connues de l'art antérieur peuvent présenter des difficultés d'insertion des tubes d'échange thermique dans le collecteur.According to a known solution, a collector box with a flat bottom may have so-called inverted collars, that is to say made in the direction opposite to the direction of insertion of a heat exchange tube. The collars then have a flared shape oriented towards the opposite of the volume defined by the manifold. However, such inverted collars have a low flare, in other words the known inverted collars define a small inlet cone for the insertion of the heat exchange tubes. The inlet cone may therefore not be sufficient to allow simple insertion of the heat exchange tubes, and the solutions known from the prior art may present difficulties in inserting the heat exchange tubes into the manifold.

Du fait de cette difficulté d'insertion des tubes d'échange thermique dans le collecteur présentant de tels collets inversés, une telle solution de collets inversés pour un collecteur à fond arrondi n'est pas envisagée dans l'art antérieur au bénéfice des collets dits standards.Due to this difficulty of inserting the heat exchange tubes into the manifold having such inverted collars, such an inverted collars solution for a rounded bottom collector is not envisaged in the prior art for the benefit of so-called collars. standards.

L'invention a pour objectif de proposer une boîte collectrice permettant de résoudre ces problèmes de l'art antérieur.The object of the invention is to provide a collector box making it possible to solve these problems of the prior art.

À cet effet, l'invention a pour objet une boîte collectrice pour échangeur thermique comportant un collecteur présentant une forme au moins partiellement arrondie et comprenant une pluralité d'ouvertures pour le passage d'une pluralité de tubes d'échange thermique de l'échangeur thermique, et une pluralité de collets entourant les ouvertures,
caractérisée en ce que le collecteur comporte en outre une pluralité d'ondulations, et en ce que les collets sont réalisés au niveau des ondulations du collecteur et présentent respectivement une forme sensiblement évasée dirigée du côté opposé au volume défini par la boîte collectrice.To this end, the invention relates to a manifold for an exchanger thermal comprising a manifold having an at least partially rounded shape and comprising a plurality of openings for the passage of a plurality of heat exchange tubes of the heat exchanger, and a plurality of collars surrounding the openings,
characterized in that the collector further comprises a plurality of corrugations, and in that the collars are produced at the level of the corrugations of the collector and respectively have a substantially flared shape directed on the side opposite to the volume defined by the collector box.

Selon l'invention, les collets sont formés au niveau de sommets des ondulations orientés vers l'opposé du volume défini par la boîte collectrice.According to the invention, the collars are formed at the level of the tops of the corrugations oriented towards the opposite of the volume defined by the manifold.

Une telle boîte au moins partiellement arrondie est adaptée pour tenir la pression dans des applications à haute pression, et le collecteur avec de tels collets inversés, c'est-à-dire dont la direction est opposée par rapport à la direction habituelle d'insertion des tubes, permet de recevoir les extrémités des tubes qui, auparavant, faisaient saillie à l'intérieur du volume défini par la boîte collectrice.Such an at least partially rounded box is adapted to withstand the pressure in high pressure applications, and the manifold with such inverted collars, that is to say whose direction is opposite to the usual direction of insertion. tubes, makes it possible to receive the ends of the tubes which, previously, protruded inside the volume defined by the manifold.

Les extrémités des tubes ne débouchent donc plus dans le volume défini par la boîte collectrice. Il en résulte une réduction significative de la perte de charge liée à l'écoulement d'un fluide dans les tubes de l'échangeur thermique.The ends of the tubes therefore no longer open into the volume defined by the manifold box. This results in a significant reduction in the pressure drop associated with the flow of a fluid in the tubes of the heat exchanger.

En conclusion, en combinant un collecteur au moins partiellement arrondi et une pluralité d'ondulations, il y a suffisamment de matière pour la formation des collets inversés suffisamment évasés pour faciliter l'introduction des tubes d'échange thermique. En effet, les collets inversés selon l'invention définissent une ouverture d'entrée pour l'insertion des tubes d'échange thermique, en forme sensiblement de tulipe, qui est suffisamment grande grâce à cet apport de matière.In conclusion, by combining an at least partially rounded collector and a plurality of corrugations, there is sufficient material for the formation of the inverted collars sufficiently flared to facilitate the introduction of the heat exchange tubes. In fact, the inverted collars according to the invention define an inlet opening for the insertion of heat exchange tubes, in the shape of a substantially tulip, which is sufficiently large thanks to this supply of material.

Ladite boîte selon l'invention comporte par ailleurs les caractéristiques suivantes

  • l'amincissement de la matière au niveau d'un collet est au moins supérieur à 30% de l'épaisseur initiale de la matière, voire localement supérieur à 50% de l'épaisseur initiale de la matière. En amincissant la matière on peut allonger les collets pour obtenir un évasement suffisamment grand pour faciliter l'introduction des tubes.
Said collector box may also include one or more of the following characteristics, taken separately or in combination:

On a représenté de façon schématique et simplifiée sur la figure 1, une boîte collectrice 1 de fluide pour un échangeur thermique (non représenté) notamment dans le domaine de l'automobile. L'échangeur thermique peut être utilisé en particulier en tant que radiateur ou condenseur pour véhicule automobile.There is shown schematically and simplified on the figure 1 , a fluid manifold 1 for a heat exchanger (not shown) in particular in the automotive field. The heat exchanger can be used in particular as a radiator or condenser for a motor vehicle.

En particulier, l'invention peut s'appliquer pour un échangeur thermique brasé.In particular, the invention can be applied for a brazed heat exchanger.

L'échangeur thermique comporte un faisceau de tubes 3. Seule une extrémité d'un tube 3 est visible sur la figure 2. Les tubes 3 sont par exemple réalisés en aluminium ou en alliage d'aluminium. Il s'agit par exemple de tubes 3 sensiblement aplatis.The heat exchanger comprises a bundle of tubes 3. Only one end of a tube 3 is visible on the figure 2 . The tubes 3 are for example made of aluminum or of an aluminum alloy. These are for example substantially flattened tubes 3.

La boîte collectrice 1 est configurée pour recevoir, au moins une extrémité d'un tube 3 de l'échangeur thermique, plus précisément pour recevoir les extrémités d'une multiplicité de tubes 3, de l'échangeur thermique (non illustré). Seule une extrémité d'un tube 3 est visible sur la figure 2.The manifold 1 is configured to receive at least one end of a tube 3 of the heat exchanger, more precisely to receive the ends of a multiplicity of tubes 3, of the heat exchanger (not shown). Only one end of a tube 3 is visible on the figure 2 .

La boîte collectrice 1 comprend à cet effet un collecteur 5. La boîte collectrice 1 comporte en outre un couvercle 6 fixé au collecteur 5, de manière à fermer la boîte collectrice 1.The manifold 1 comprises for this purpose a manifold 5. The manifold 1 further comprises a cover 6 fixed to the manifold 5, so as to close the manifold 1.

Le collecteur 5 est par exemple réalisé en aluminium ou en alliage d'aluminium. Le couvercle 6 quant à lui peut être réalisé en aluminium en alliage d'aluminium, ou en variante en plastique.The collector 5 is for example made of aluminum or an aluminum alloy. The cover 6 for its part can be made of aluminum in an aluminum alloy, or in a variant of plastic.

Le couvercle 6 peut être fixé au collecteur 5 par exemple par clipsage, par brasage ou encore par sertissage.The cover 6 can be fixed to the manifold 5, for example by clipping, by brazing or even by crimping.

En outre, le collecteur 5 comporte une pluralité d'ouvertures 7 pour le passage des extrémités des tubes 3.In addition, the manifold 5 has a plurality of openings 7 for the passage of the ends of the tubes 3.

Les ouvertures 7 présentent par exemple une forme sensiblement allongée, telles que des fentes.The openings 7 have for example a substantially elongated shape, such as slits.

Les extrémités des tubes 3 reçues dans les ouvertures 7 peuvent ensuite être brasées par exemple au collecteur 5.The ends of the tubes 3 received in the openings 7 can then be soldered, for example to the manifold 5.

Selon un mode de réalisation, les tubes d'échange thermique 3 présentent une hauteur comprise entre 0,8mm et 2,5mm, de préférence entre 1,2 mm et 1,8mm.According to one embodiment, the heat exchange tubes 3 have a height of between 0.8mm and 2.5mm, preferably between 1.2mm and 1.8mm.

Le pas des tubes d'échange thermique 3, c'est-à-dire l'entraxe entre deux tubes d'échange thermique 3, est par exemple compris entre 5mm et 10mm, de préférence entre 6 mm et 8mm.The pitch of the heat exchange tubes 3, that is to say the center distance between two heat exchange tubes 3, is for example between 5mm and 10mm, preferably between 6mm and 8mm.

Selon le mode de réalisation illustré le collecteur 5 présente une paroi 8 formant un fond de boîte. La boîte collectrice 1 comporte de plus des parois latérales 8' raccordées à ce fond de boîte 8.According to the illustrated embodiment, the collector 5 has a wall 8 forming a box bottom. The collector box 1 further comprises side walls 8 'connected to this box bottom 8.

Il s'agit d'un fond de boîte 8 de forme au moins partiellement arrondie.This is a box bottom 8 of at least partially rounded shape.

Selon le mode de réalisation illustré, la paroi 8 formant fond de boîte, aussi appelée paroi de fond 8, présente une forme sensiblement bombée vers l'extérieur du volume défini par la boîte collectrice 1. Ainsi, la paroi de fond 8 du collecteur 5 présente une forme sensiblement concave par rapport au volume intérieur défini par la boîte collectrice 1, et sensiblement convexe par rapport au faisceau de tubes 3 de l'échangeur thermique dont la convexité est orientée vers l'extérieur du volume défini par la boîte collectrice 1.According to the illustrated embodiment, the wall 8 forming the bottom of the box, also called the bottom wall 8, has a shape which is substantially convex towards the outside of the volume defined by the manifold 1. Thus, the bottom wall 8 of the manifold 5 has a shape that is substantially concave with respect to the interior volume defined by the manifold 1, and substantially convex with respect to the bundle of tubes 3 of the heat exchanger, the convexity of which is oriented towards the outside of the volume defined by the manifold 1.

Comme cela est visible sur les figures 1 à 3, la boîte collectrice 1 comporte de plus un nombre prédéfini de collets 9 formés sur le collecteur 5 au niveau des ouvertures 7 pour recevoir les extrémités de tubes 3. Plus précisément, chaque ouverture 7 est entourée par un collet 9. Les collets 9 sont ici réalisés sans enlèvement de matière.As can be seen on the figures 1 to 3 , the collector box 1 further comprises a predefined number of collars 9 formed on the collector 5 at the level of the openings 7 to receive the ends of tubes 3. More precisely, each opening 7 is surrounded by a collar 9. The collars 9 are here produced without removing material.

Le collecteur 5 comporte de plus une pluralité de déformations 11. Ces déformations 11 sont réalisées au niveau de la paroi de fond 8 sensiblement bombée du collecteur 5. Les déformations 11 sont par exemple réalisées de manière à former un motif régulier.The manifold 5 further comprises a plurality of deformations 11. These deformations 11 are produced at the level of the substantially domed bottom wall 8 of the manifold 5. The deformations 11 are for example produced so as to form a regular pattern.

Selon le mode de réalisation illustré, il s'agit d'ondulations ou vagues 11.According to the illustrated embodiment, these are ripples or waves 11.

Les ondulations 11 peuvent être réalisées de façon symétrique par rapport à l'axe longitudinal de la paroi de fond 8 du collecteur 5. Les ondulations 11 présentent donc des sommets s'étendant alternativement de part et d'autre de l'axe longitudinal de la paroi de fond 8 du collecteur 5. Autrement dit, les ondulations 11 présentent par exemple une pluralité de sommets dirigés vers l'intérieur du volume défini par la boîte collectrice 1 et une pluralité de sommets opposés dirigés vers l'opposé du volume défini par la boîte collectrice, et donc vers l'extérieur de la boîte collectrice 1 et vers le faisceau de tubes 3 de l'échangeur thermique.The corrugations 11 can be produced symmetrically with respect to the longitudinal axis of the bottom wall 8 of the collector 5. The corrugations 11 therefore have peaks extending alternately on either side of the longitudinal axis of the collector. bottom wall 8 of the manifold 5. In other words, the corrugations 11 have for example a plurality of vertices directed towards the interior of the volume defined by the manifold 1 and a plurality of opposite vertices directed towards the opposite of the volume defined by the manifold box, and therefore towards the outside of the manifold 1 and towards the tube bundle 3 of the heat exchanger.

Les collets 9, mieux visibles sur les figures 4a, 4b, sont formés au niveau des ondulations 11, plus précisément aux sommets des ondulations 11 dirigés vers l'opposé du volume défini par la boîte collectrice. En particulier, les ouvertures 7 sont formées en perçant ou perforant le collecteur 5 aux sommets des ondulations 11 dirigés vers l'opposé du volume défini par la boîte collectrice, et les collets 9 sont réalisés par la matière autour de ces ouvertures 7.The collars 9, better visible on the figures 4a, 4b , are formed at the level of the corrugations 11, more precisely at the tops of the corrugations 11 directed towards the opposite of the volume defined by the manifold. In particular, the openings 7 are formed by piercing or perforating the collector 5 at the tops of the corrugations 11 directed towards the opposite of the volume defined by the collector box, and the collars 9 are produced by the material around these openings 7.

Afin de pouvoir avoir suffisamment de matière pour former les collets 9 au niveau des ondulations 11, les ondulations 11 sont réalisées avec une hauteur h suffisante (cf figure 5), par exemple avec une hauteur h supérieure de l'ordre de 30% du pas de tube.In order to be able to have sufficient material to form the collars 9 at the level of the corrugations 11, the corrugations 11 are made with a sufficient height h (cf. figure 5 ), for example with a greater height h of the order of 30% of the tube pitch.

Les collets 9 ainsi formés sont dirigés vers l'opposé du volume défini par la boîte collectrice 1, à savoir vers le faisceau de tubes 3 de l'échangeur thermique. On parle de collets 9 inversés.The collars 9 thus formed are directed towards the opposite of the volume defined by the manifold 1, namely towards the bundle of tubes 3 of the heat exchanger. We are talking about inverted 9 snares.

Ainsi, en se référant de nouveau à la figure 2 et à la figure 6, lorsque l'extrémité d'un tube 3 de l'échangeur thermique est insérée dans une ouverture 7 entourée par un tel collet 9 inversé, cette extrémité de tube 3 se trouve dans une zone Z située entre les sommets des ondulations 11 qui sont orientés vers l'intérieur du volume défini par la boîte collectrice 1 et le niveau du fond de boîte 8 du collecteur 5, mais ne dépasse pas dans le volume défini par la boîte collectrice 1. L'absence de tubes 3 débouchant dans le volume de la boîte collectrice 1 permet d'améliorer les performances en termes d'écoulement du fluide.Thus, referring again to the figure 2 and at the figure 6 , when the end of a tube 3 of the heat exchanger is inserted into an opening 7 surrounded by such an inverted collar 9, this tube end 3 is located in a zone Z located between the tops of the corrugations 11 which are oriented towards the interior of the volume defined by the manifold 1 and the level of the bottom of the box 8 of the manifold 5, but does not protrude into the volume defined by the manifold 1. The absence of tubes 3 opening into the volume of the collector box 1 improves performance in terms of fluid flow.

Les collets 9 présentent une hauteur h' suffisante propre à permettre l'insertion des extrémités des tubes 3, par exemple de l'ordre de la moitié de la hauteur h d'une ondulation 11.The collars 9 have a sufficient height h 'suitable for allowing the insertion of the ends of the tubes 3, for example of the order of half the height h of a corrugation 11.

En outre, les collets 9 présentent une forme générale évasée, telle qu'une forme de tulipe.In addition, the collars 9 have a generally flared shape, such as a tulip shape.

Plus précisément, les collets 9 présentent respectivement une forme sensiblement conique, par exemple d'angle α de l'ordre de 30° (cf. figure 5).More precisely, the collars 9 respectively have a shape substantially conical, for example with an angle α of the order of 30 ° (cf. figure 5 ).

Un collet 9 présente donc deux bords 9a, 9b évasés, correspondants aux deux grands bords, raccordés entre eux par deux petits bords 9c, 9d.A collar 9 therefore has two flared edges 9a, 9b, corresponding to the two large edges, connected to each other by two small edges 9c, 9d.

Cette forme évasée, ou sensiblement conique, facilite l'introduction des extrémités des tubes 3 dans le collecteur 5, depuis l'extérieur du volume défini par la boîte collectrice 1 vers l'intérieur du volume défini par la boîte collectrice 1.This flared, or substantially conical, shape facilitates the introduction of the ends of the tubes 3 into the manifold 5, from outside the volume defined by the manifold 1 towards the interior of the volume defined by the manifold 1.

Les deux bords évasés 9a, 9b présentent par exemple une forme sensiblement convexe dont la convexité est orientée vers l'extérieur du volume défini par la boîte collectrice 1.The two flared edges 9a, 9b have for example a substantially convex shape, the convexity of which is oriented towards the outside of the volume defined by the manifold box 1.

En référence à la figure 5, les collets 9 en forme de tulipe présentent respectivement :

  • une première largeur l1 au niveau du sommet percé ou perforé de l'ondulation 11 associée qui correspond à la plus petite largeur du collet 9, et
  • une deuxième largeur l2 périphérique, qui correspond à la plus grande largeur du collet 9.
With reference to the figure 5 , the collars 9 in the shape of a tulip have respectively:
  • a first width l 1 at the level of the pierced or perforated top of the associated corrugation 11 which corresponds to the smallest width of the collar 9, and
  • a second peripheral width l 2 , which corresponds to the greatest width of the collar 9.

La première largeur l1 est sensiblement égale ou légèrement supérieure à la largeur d'un tube 3 destiné à être inséré dans l'ouverture 7.The first width 11 is substantially equal to or slightly greater than the width of a tube 3 intended to be inserted into the opening 7.

La plus grande largeur l2 définit l'ouverture 7 entourée par le collet 9 pour l'insertion de l'extrémité d'un tube 3. La deuxième largeur l2 est prévue suffisamment large pour permettre une insertion simple, et notamment en même temps, des extrémités de l'ensemble des tubes 3 de l'échangeur thermique (non représenté) dans les ouvertures 7. La deuxième largeur l2 est par exemple de l'ordre du double de la première largeur l1 du collet 9.The largest width l 2 defines the opening 7 surrounded by the collar 9 for inserting the end of a tube 3. The second width l 2 is provided sufficiently wide to allow simple insertion, and in particular at the same time. , of the ends of all the tubes 3 of the heat exchanger (not shown) in the openings 7. The second width l 2 is for example of the order of twice the first width l 1 of the collar 9.

Par ailleurs, les collets 9 peuvent être amincis par rapport aux ondulations 11 sur le collecteur 5. En effet, en référence à la figure 6, une ondulation 11 présente par exemple une première épaisseur e1, et le collet 9 présente une deuxième épaisseur e2 inférieure à la première épaisseur e1 de l'ondulation 11.Furthermore, the collars 9 can be thinned with respect to the corrugations 11 on the collector 5. Indeed, with reference to the figure 6 , a corrugation 11 has for example a first thickness e 1 , and the collar 9 has a second thickness e 2 less than the first thickness e 1 of the corrugation 11.

Le collet 9 peut être aminci aussi bien au niveau des grands bords évasés 9a, 9b que des petits bords de raccordement 9c et 9d.The collar 9 can be thinned both at the large flared edges 9a, 9b and at the small connecting edges 9c and 9d.

À titre d'exemple, on réalise un amincissement de la matière au niveau du collet 9 qui peut aller au delà de 30%, voire localement au-delà de 50% de l'épaisseur initiale de la matière.By way of example, a thinning of the material is carried out at the level of the collar 9 which can go beyond 30%, or even locally beyond 50% of the initial thickness of the material.

En amincissant la matière au niveau d'un collet 9 on peut allonger ce collet 9.By thinning the material at the level of a collar 9, this collar 9 can be lengthened.

On comprend donc qu'un collecteur 5 comprenant de tels collets inversés 9 permet de faciliter l'introduction des extrémités de la multiplicité de tubes d'échange thermique 3 de l'échangeur thermique en même temps et de façon simple sans nécessiter d'outillage spécifique notamment pour guider chaque tube 3 dans l'ouverture 7 associée.It is therefore understood that a manifold 5 comprising such inverted collars 9 makes it possible to facilitate the introduction of the ends of the multiplicity of heat exchange tubes 3 of the heat exchanger at the same time and in a simple manner without requiring specific tools. in particular to guide each tube 3 in the associated opening 7.

En effet, les collets 9 inversés et évasés offrent une ouverture suffisante pour l'introduction depuis l'extérieur de la boîte collectrice 1 vers l'intérieur du volume défini par la boîte collectrice 1.Indeed, the inverted and flared collars 9 offer a sufficient opening for the introduction from the outside of the manifold 1 towards the interior of the volume defined by the manifold 1.

Enfin, ces collets inversés 9 permettent l'insertion des extrémités des tubes 3 sans que ces extrémités ne débouchent à l'intérieur du volume défini par la boîte collectrice 1 favorisant ainsi l'écoulement du fluide à l'intérieur de la boîte collectrice 1.Finally, these inverted collars 9 allow the insertion of the ends of the tubes 3 without these ends opening out inside the volume defined by the manifold 1 thus promoting the flow of fluid inside the manifold 1.
