Definitions
- the invention relates to the field of heat exchangers and more particularly relates to a manifold collector, of the type corresponding to the preamble of claim 1, as disclosed in FR 2745 079 .
- collectors are used in particular in collector boxes obtained by assembling two collector pieces, namely a collector and a cover, the collector being most often made of aluminum or aluminum-based alloy.
- Such manifolds are used in heat exchangers and in particular in radiators for cooling the motor or the charge air of motor vehicles.
- the coolant or charge air which circulates in the header and in the tubes, is at a high pressure and at a temperature that may exceed 100 ° C.
- One of the main difficulties in designing such manifolds is obtaining good pressure resistance for the manifold, without using too much material width to make it.
- the collector has a substantially U-shaped section, and its thickness is doubled by a fold of material at the connection between the branches of the U and the bottom thereof.
- This type of design increases the use of raw material, occupies a lot of space, and the need to braze the collector on itself at the level of the folds prevents inter alia the use of an anticorrosive coating inside that -this.
- a collecting plate having openings in a substantially planar region which is connected to at least one generally cylindrical curved region deviating from the plane of the planar region, wherein the cylindrical shape is interrupted by a multiplicity of withdrawal. Although it offers good resistance to fracture, this type of collector plate is nevertheless particularly poorly adapted to the insertion of the tubes.
- the invention aims to improve the situation.
- the invention proposes for this purpose a collector, of the type comprising a substantially flat plate with holes for receiving tubes of a heat exchanger, as well as raised lateral edges extending at an angle of said plate and connected to that by at least one curved portion of the plate further comprising additional ribs between at least one of said holes, the ribs of the plate each have a convexity extending substantially in the opposite direction to the direction of extension of the lateral edges, and wherein in the curved portion are formed ribs each having a convexity extending substantially in the direction of extension of the lateral edges.
- the ribs of the plate are disposed between each of the holes, and each hole is thus surrounded by two ribs whose convexities form a tube insertion guide.
- Such a collector is particularly interesting in that it offers a high resistance to the pressure at break thanks to the ribs made, while offering the possibility of guiding the tubes for their insertion.
- the lateral edges also have ribs, the ribs of each lateral edge being each able to have a convexity extending in the directions of the opposite lateral edge. At least some of the ribs of the lateral edges may be arranged in continuity with the ribs of the curved portion, or on the contrary be arranged on the manifold alternately with the ribs of the curved portion.
- the ribs of the lateral edges extend over a portion of the lateral edges not including the end thereof.
- Such a collector is further reinforced by the presence of the ribs on the lateral edges.
- the positioning of the ribs of the lateral edges in the continuity or on the contrary alternating with the ribs of the curved portion makes it possible to better control the characteristics of the deformation of the collector.
- positioning the convexity of the ribs to the opposite side edge, that is to say towards the inside of the manifold when it mounted saves space.
- the limited extent of the ribs of the lateral edges makes it possible to position a cover inside the edges of the collector, to which it can then be fixed according to known methods.
- the collector has a substantially U-shaped section, whose branches form the lateral edges.
- the collector can also be made of aluminum or aluminum alloy.
- the invention also relates to a collector box which comprises a collector having the characteristics mentioned above, and a cover for closing the collector.
- the collector and the cover both have a substantially U-shaped cross-section.
- the branches of this U form respective lateral edges for the two collector members, the cover being adapted to be brazed on at least one part of the lateral edges of the collector, in the vicinity of the end of the latter.
- FIG 1 shows a heat exchanger 10 comprising a manifold 12 according to the invention, in which open ends of tubes 14 of a heat exchange bundle.
- the tubes 14 are flat parallel tubes between which are arranged corrugated inserts 16 forming heat exchange fins.
- the exchanger 10 comprises an opposite header (not shown) similar to the manifold 12.
- the heat exchanger 10 finds particular application in motor vehicles and is designed to be made by soldering in a single operation while offering significant pressure and rupture performance.
- the manifold 12 consists of two nested metal parts to be assembled by brazing.
- the manifold 12 comprises a manifold 18 made in the form of a U-shaped metal element (for example aluminum or aluminum alloy) having a bottom wall or plate 20, provided with holes 22 for
- the manifold also has two side walls or side edges 24 connected to the plate 20.
- the side walls 24 of the manifold 18 forming the two branches of the U are of identical height, the height being able however to vary with respect to the bottom wall 20.
- the plate 20 is generally flat and it is the same side edges 24. The latter are connected to the plate 20 at an angle of about 90 °. This angle could be different.
- the connection of the plate 20 and the lateral edges 24 is effected by curved portions 26.
- the lateral edges 24 have a variable height in the vicinity of the end of the collector 18.
- the lateral edges 24 of the collector comprise two curved portions 28 which each extend to the plate 20.
- the manifold 12 comprises another part, namely a lid 30 made in the form of a U-shaped metal element (for example aluminum or an aluminum alloy) having a bottom wall 32, extending in a plane parallel to the plane of extension of the plate 20, and two side walls 34 connected to the bottom wall 32.
- the lateral edges 34 of the lid are generally planar and make an angle of about 90 ° with the bottom wall 32.
- the side walls 34 of the cover 30 forming the two branches of the U may be of identical height.
- the cover 30 is fitted into the manifold 18 so that their respective U-profiles are oriented in the same direction, that is to say opposite the tubes 14 of the heat exchanger bundle.
- the cover 30 further comprises two end regions 36 ( figure 3 ) each of which is bent towards the plate 20 of the manifold 18.
- the bottom wall 32 of the lid has a curved portion 38 terminated by a rim 40 which bears against the plate 20 18.
- the flange 40 connects itself to a centered portion 42 of each side edge of the lid to close the manifold 12.
- the collector 12 is advantageously made by folding a metal sheet clean to impart a U-shaped profile, the holes 22 for the insertion of the tubes 14 being preferably made in the metal part after folding.
- the lid 30 is advantageously made by stamping, the end portions of the lid being also made in this stamping operation.
- FIG 4 is a partial perspective view of the manifold 12 which provides a better view of the distribution of the ribs.
- the collector 18 is stamped to form three distinct types of ribs at the plate 20, lateral edges 24 and curved portions 26.
- Ribs 50 are first made between each of the holes 22.
- the ribs 50 extend over the entire width of the plate 20, between the curved portions 26 of the lateral edges 24.
- the ribs 50 thus extend regularly over the length of the collector 18.
- the ribs 50 have a substantially V-shaped section, and are made outwardly of the box 12.
- the ribs 50 thus have a convexity extending substantially in the opposite direction to the direction of extension of the side edges.
- the ribs 50 thus form protrusions surrounding the holes 22.
- Each pair of ribs 50 surrounding a given hole 22 forms an insertion guide for the tubes 14, each using a branch of the V constituting it.
- ribs 50 Other types of section are possible for the ribs 50, to allow insertion further better tubes 14 while ensuring optimum rigidity to the manifold 18.
- Ribs 52 are formed in the curved portions 26. Like the ribs 50, the ribs 52 extend in the width direction of the plate 20, and they are each arranged opposite a rib 50 in the continuity of that -this.
- the ribs 52 are formed towards the inside of the box 12.
- the ribs 52 thus have a convexity extending substantially in the direction of extension of the lateral edges 24.
- a region 54 makes it possible to connect each rib 50 to the rib 52 which is in its continuity and expresses itself in a substantially opposite direction.
- the ribs 52 can significantly increase the resistance to pressure and breaking. This aspect is all the more critical as, traditionally, the portions 26 constitute important weak points for the collector boxes of the type of the box 12.
- ribs 56 are formed in the lateral edges 24. Like the ribs 50 and 52, the ribs 56 extend in the width direction of the plate 20, and they are each arranged opposite a rib 52, in the continuity of this one.
- the ribs 56 are also formed towards the inside of the box 12.
- the ribs 56 thus have a convexity extending substantially in the direction of the opposite lateral edge.
- the ribs 56 extend over most of the lateral edges 24, up to a selected distance the end of the edges 24 which allows the housing and brazing of the cover 30 in the manifold 18.
- the ribs 50, 52 and 56 are not only in continuity with each other, but also continuous. These ribs thus form a rib which extends over the entire width of the collector 18, from a position close to the end of a lateral edge to another position close to the end of the opposite lateral edge, via the plate.
- all the holes 22 shown are bordered with ribs 50, 52 and 56, it is not excluded that the holes 22 at the ends of the plate 20 are bordered by a single rib 50, 52 or 56 or not at all.
- the ribs 50 and 52 are unchanged in their constitution and their arrangement.
- the ribs 56 are offset, and each disposed opposite a hole 22, that is to say alternately with a rib 52.

Description
L'invention se rapporte au domaine des échangeurs de chaleur et elle concerne plus particulièrement un collecteur pour boîte collectrice, du type correspondant au préambule de la revendication 1, comme divulgué dans
De tels collecteurs sont utilisés en particulier dans des boîtes collectrices obtenues par l'assemblage de deux pièces collectrices, à savoir un collecteur et un couvercle, le collecteur étant le plus souvent réalisé en aluminium ou en alliage à base d'aluminium.Such collectors are used in particular in collector boxes obtained by assembling two collector pieces, namely a collector and a cover, the collector being most often made of aluminum or aluminum-based alloy.
De telles boîtes collectrices sont utilisées dans des échangeurs de chaleur et en particulier dans des radiateurs servant au refroidissement du moteur ou de l'air de suralimentation de véhicules automobiles. Dans de tels radiateurs, le liquide de refroidissement ou l'air de suralimentation, qui circule dans la boîte collectrice et dans les tubes, est à une pression importante et à une température qui peut dépasser 100°C. L'une des principales difficultés dans la conception de telles boîtes collectrices est l'obtention d'une bonne résistance à la pression pour le collecteur, sans utiliser une largeur trop importante de matériau pour le réaliser.Such manifolds are used in heat exchangers and in particular in radiators for cooling the motor or the charge air of motor vehicles. In such radiators, the coolant or charge air, which circulates in the header and in the tubes, is at a high pressure and at a temperature that may exceed 100 ° C. One of the main difficulties in designing such manifolds is obtaining good pressure resistance for the manifold, without using too much material width to make it.
On connaît déjà certaines boîtes collectrices dont la conception vise à résoudre ce problème, comme celle présentée dans
Par
L'invention vise à améliorer la situation.The invention aims to improve the situation.
L'invention propose à cet effet un collecteur, du type comprenant une plaque sensiblement plane avec des trous pour recevoir des tubes d'un échangeur de chaleur, ainsi que des bords latéraux relevés s'étendant à un angle de ladite plaque et reliés à celle-ci par au moins une portion incurvée la plaque comportant en outre des nervures supplémentaires entre certains au moins desdits trous, les nervures de la plaque présentent chacune une convexité s'étendant sensiblement dans la direction opposée à la direction d'extension des bords latéraux, et où dans la portion incurvée sont réalisées des nervures présentant chacune une convexité s'étendant sensiblement dans la direction d'extension des bords latéraux.The invention proposes for this purpose a collector, of the type comprising a substantially flat plate with holes for receiving tubes of a heat exchanger, as well as raised lateral edges extending at an angle of said plate and connected to that by at least one curved portion of the plate further comprising additional ribs between at least one of said holes, the ribs of the plate each have a convexity extending substantially in the opposite direction to the direction of extension of the lateral edges, and wherein in the curved portion are formed ribs each having a convexity extending substantially in the direction of extension of the lateral edges.
Dans un mode de réalisation, les nervures de la plaque sont disposées entre chacun des trous, et chaque trou est ainsi entouré par deux nervures dont les convexités forment un guide d'insertion de tube.In one embodiment, the ribs of the plate are disposed between each of the holes, and each hole is thus surrounded by two ribs whose convexities form a tube insertion guide.
Un tel collecteur est particulièrement intéressant en ce qu'il offre une forte résistance à la pression à la rupture grâce aux nervures réalisées, tout en offrant la possibilité de guider les tubes pour leur insertion.Such a collector is particularly interesting in that it offers a high resistance to the pressure at break thanks to the ribs made, while offering the possibility of guiding the tubes for their insertion.
Dans un autre mode de réalisation, les bords latéraux comportent également des nervures, les nervures de chaque bord latéral pouvant présenter chacune une convexité s'étendant dans les directions du bord latéral opposé. Certaines au moins des nervures des bords latéraux peuvent être disposées dans la continuité des nervures de la portion incurvée, ou au contraire être disposées sur le collecteur de manière alternée avec les nervures de la portion incurvée. Avantageusement, les nervures des bords latéraux s'étendent sur une partie des bords latéraux ne comprenant pas l'extrémité de ces derniers.In another embodiment, the lateral edges also have ribs, the ribs of each lateral edge being each able to have a convexity extending in the directions of the opposite lateral edge. At least some of the ribs of the lateral edges may be arranged in continuity with the ribs of the curved portion, or on the contrary be arranged on the manifold alternately with the ribs of the curved portion. Advantageously, the ribs of the lateral edges extend over a portion of the lateral edges not including the end thereof.
Un tel collecteur est encore renforcé par la présence des nervures sur les bords latéraux. Le positionnement des nervures des bords latéraux dans la continuité ou au contraire en alternance avec les nervures de la portion incurvée permet de mieux maîtriser les caractéristiques de déformation du collecteur. En outre, le positionnement de la convexité des nervures vers le bord latéral opposé, c'est-à-dire vers l'intérieur de la boîte collectrice lorsque celle-ci montée, permet d'économiser de l'espace. Enfin, l'étendue limitée des nervures des bords latéraux permet de venir positionner un couvercle à l'intérieur des bords du collecteur, auquel il peut être alors fixé selon des méthodes connues.Such a collector is further reinforced by the presence of the ribs on the lateral edges. The positioning of the ribs of the lateral edges in the continuity or on the contrary alternating with the ribs of the curved portion makes it possible to better control the characteristics of the deformation of the collector. In addition, positioning the convexity of the ribs to the opposite side edge, that is to say towards the inside of the manifold when it mounted, saves space. Finally, the limited extent of the ribs of the lateral edges makes it possible to position a cover inside the edges of the collector, to which it can then be fixed according to known methods.
Dans un mode de réalisation, le collecteur a une section sensiblement en U, dont les branches forment les bords latéraux. Le collecteur peut être également réalisé en aluminium ou en alliage d'aluminium.In one embodiment, the collector has a substantially U-shaped section, whose branches form the lateral edges. The collector can also be made of aluminum or aluminum alloy.
L'invention concerne également une boîte collectrice qui comporte un collecteur ayant les caractéristiques citées ci-dessus, et un couvercle pour fermer le collecteur.The invention also relates to a collector box which comprises a collector having the characteristics mentioned above, and a cover for closing the collector.
Dans un mode de réalisation, le collecteur et le couvercle ont tous les deux une section sensiblement en forme de U. Les branches de ce U forment des bords latéraux respectifs pour les deux pièces collectrices, le couvercle étant propre à être brasé sur au moins une partie des bords latéraux du collecteur, au voisinage de l'extrémité de ces derniers.In one embodiment, the collector and the cover both have a substantially U-shaped cross-section. The branches of this U form respective lateral edges for the two collector members, the cover being adapted to be brazed on at least one part of the lateral edges of the collector, in the vicinity of the end of the latter.

On se réfère d'abord à la
L'échangeur 10 trouve une application particulière dans les véhicules automobiles et est conçu pour être réalisé par brasage en une seule opération tout en offrant des performances de résistance à la pression et à la rupture importantes.The
Comme on peut le voir sur la vue en coupe de la
Comme on peut le voir sur la
La boîte collectrice 12 comporte une autre pièce, à savoir un couvercle 30 réalisé sous la forme d'un élément métallique (par exemple de l'aluminium ou un alliage d'aluminium) à profil en U présentant une paroi de fond 32, s'étendant dans un plan parallèle au plan d'extension de la plaque 20, et deux parois latérales 34 raccordées à la paroi de fond 32. Les bords latéraux 34 du couvercle sont généralement plans et font un angle d'environ 90° avec la paroi de fond 32. Comme représenté à la
Le couvercle 30 est emboîté dans le collecteur 18 de sorte que leurs profils en U respectifs sont orientés dans une même direction, c'est-à-dire à l'opposé des tubes 14 du faisceau de l'échangeur de chaleur.The
Il en résulte que les parois latérales 34 du couvercle 30 viennent en contact, par leur côté extérieur, contre une partie des bords latéraux 24 du collecteur 18, du côté intérieur de ces derniers (
Le couvercle 30 comporte en outre deux régions d'extrémité 36 (
On peut ainsi réaliser un brasage sur des surfaces importantes par un contact surfacique procurant une bonne aptitude au brasage. Le collecteur 12 est avantageusement réalisé par pliage d'une tôle métallique propre à lui conférer un profil en U, les trous 22 destinés à l'insertion des tubes 14 étant de préférence réalisés dans la pièce métallique après pliage.It is thus possible to braze on large surfaces by a surface contact providing a good solderability. The
Le couvercle 30 est pour sa part avantageusement réalisé par emboutissage, les portions d'extrémité du couvercle étant également réalisées dans cette opération d'emboutissage.The
Pour renforcer cette boîte collectrice, des nervures sont réalisées dans le collecteur 18. La
Avant pliage, le collecteur 18 est embouti pour former trois types distincts de nervures au niveau de la plaque 20, des bords latéraux 24 et des portions incurvées 26.Before folding, the
Des nervures 50 sont d'abord réalisées entre chacun des trous 22. Les nervures 50 s'étendent sur toute la largeur de la plaque 20, entre les portions incurvées 26 des bords latéraux 24. Les nervures 50 s'étendent ainsi régulièrement sur la longueur du collecteur 18.
Les nervures 50 ont une section sensiblement en forme de V, et sont réalisées vers l'extérieur de la boîte 12. Les nervures 50 présentent ainsi une convexité s'étendant sensiblement dans la direction opposée à la direction d'extension des bords latéraux.The
Les nervures 50 forment ainsi des saillies entourant les trous 22. Chaque paire de nervures 50 entourant un trou 22 donné forme un guide d'insertion pour les tubes 14, chacune à l'aide d'une branche du V qui la constitue.The
D'autres types de section sont envisageables pour les nervures 50, afin de permettre une insertion encore meilleure des tubes 14 tout en assurant une rigidité optimale au collecteur 18.Other types of section are possible for the
Des nervures 52 sont réalisées dans les portions incurvées 26. Comme les nervures 50, les nervures 52 s'étendent dans la direction de la largeur de la plaque 20, et elle sont disposées chacune en regard d'une nervure 50 dans la continuité de celle-ci.
Les nervures 52 sont réalisées vers l'intérieur de la boîte 12. Les nervures 52 présentent ainsi une convexité s'étendant sensiblement dans la direction d'extension des bords latéraux 24. Une région 54 permet de relier chaque nervure 50 à la nervure 52 qui est dans sa continuité et qui s'exprime dans une direction sensiblement opposée.The
Les nervures 52 permettent d'accroître de manière importante la résistance à la pression et à la rupture. Cet aspect est d'autant plus critique que, traditionnellement, les portions 26 constituent des points faibles importants pour les boîtes collectrices du type de la boite 12.The
Enfin, des nervures 56 sont réalisées dans les bords latéraux 24. Comme les nervures 50 et 52, les nervures 56 s'étendent dans la direction de la largeur de la plaque 20, et elle sont disposées chacune en regard d'une nervure 52, dans la continuité de celle-ci.Finally,
Les nervures 56 sont également réalisées vers l'intérieur de la boîte 12. Les nervures 56 présentent ainsi une convexité s'étendant sensiblement dans la direction du bord latéral opposé. Les nervures 56 s'étendent sur la majeure partie des bords latéraux 24, jusqu'à une distance choisie de l'extrémité des bords 24 qui permet le logement et le brasage du couvercle 30 dans le collecteur 18.The
Dans l'exemple ici décrit, les nervures 50, 52 et 56 sont non seulement dans la continuité les unes des autres, mais également continues. Ces nervures forment ainsi une nervure qui s'étend sur toute la largeur du collecteur 18, d'une position proche de l'extrémité d'un bord latéral à une autre position proche de l'extrémité du bord latéral opposé, en passant par la plaque. En outre, si tous les trous 22 représentés sont bordés de nervures 50, 52 et 56, il n'est pas exclu que les trous 22 aux extrémités de la plaque 20 ne soient bordés que d'une seule nervure 50, 52 ou 56 ou pas du tout.In the example described here, the
Dans un autre mode de réalisation représenté sur la
L'invention ne se limite pas aux échangeurs de chaleur dont les boîtes collectrices sont réalisées en aluminium ou en alliage d'aluminium. Elle peut notamment s'appliquer à des boîtes collectrices à plaque et à couvercle en matière plastique, des nervures étant réalisées par exemple au niveau de la gorge de la plaque collectrice et entre les trous qu'elle comporte.The invention is not limited to heat exchangers whose collector boxes are made of aluminum or aluminum alloy. It can in particular apply to plastic plate and cover manifolds, ribs being made for example at the groove of the collector plate and between the holes therein.
En outre, l'homme du métier saura envisager l'ensemble des variantes qui s'imposent à la lecture des revendications qui suivent.In addition, the skilled person will consider all the variations that are necessary to read the following claims.
