Description

Bride de connexion pour thermique  Connection flange for thermal
L'invention concerne notamment une bride d'une boîte collectrice d'un échangeur thermique, notamment pour véhicule automobile. The invention relates in particular to a flange of a manifold of a heat exchanger, in particular for a motor vehicle.
On connaît déjà des échangeurs thermiques utilisés dans les véhicules automobiles, par exemple comme condenseur dans un circuit de climatisation.  Heat exchangers used in motor vehicles are already known, for example as a condenser in an air conditioning circuit.
Un tel circuit comporte généralement un compresseur, un condenseur ou refroidisseur de gaz, un détendeur et un évaporateur. Le condenseur est agencé de façon à condenser et/ou refroidir le premier fluide par échange thermique avec le second fluide.  Such a circuit generally includes a compressor, a gas condenser or cooler, a pressure reducer and an evaporator. The condenser is arranged so as to condense and / or cool the first fluid by heat exchange with the second fluid.
Dans ce cas, le premier fluide mis en œuvre peut être un fluide réfrigérant, tel qu'un fluide à base de fréon, et le second fluide par un fluide de refroidissement tel que de l'air.  In this case, the first fluid used can be a cooling fluid, such as a freon-based fluid, and the second fluid by a cooling fluid such as air.
Généralement, l'échangeur thermique comprend un faisceau de tubes d'échange thermique, et une boîte collectrice.  Generally, the heat exchanger comprises a bundle of heat exchange tubes, and a manifold.
La boîte collectrice peut dans certaines solutions connues être réalisée en deux parties avec un collecteur pour recevoir les extrémités des tubes et un couvercle venant se fixer sur le collecteur pour fermer la boîte collectrice en assurant l'étanchéité. Le couvercle est généralement apte à recevoir des brides de connexion formant entrée/sortie pour un fluide devant traverser l'échangeur thermique.  The manifold can in some known solutions be made in two parts with a manifold to receive the ends of the tubes and a cover which is fixed on the manifold to close the manifold ensuring sealing. The cover is generally capable of receiving connection flanges forming an inlet / outlet for a fluid which must pass through the heat exchanger.
Les demandes de brevet US2002014327A et US2014190674A décrivent des moyens de fixation de brides sur les échangeurs.  Patent applications US2002014327A and US2014190674A describe means for fixing flanges to the exchangers.
L'invention vise à améliorer l’assemblage d’échangeurs.  The invention aims to improve the assembly of exchangers.
À cet effet, l'invention a pour objet une bride de connexion pour boîte collectrice d'échangeur thermique, ladite bride définissant une entrée et/ou une sortie de fluide agencée pour être raccordée à un organe de connexion de fluide, caractérisée en ce que ladite bride comporte une portion de montage mécanique agencée pour permettre le montage mécanique sur cette bride d’un élément de montage d’un composant voisin. To this end, the subject of the invention is a connection flange for a heat exchanger manifold, said flange defining an inlet and / or an outlet for fluid arranged to be connected to a fluid connection member, characterized in that said flange comprises a mechanical mounting portion arranged to allow mechanical mounting on this flange of a mounting element of a neighboring component.
L’invention est particulièrement avantageuse quand un constructeur automobile requiert la fixation de deux échangeurs thermiques entre eux, avec un espace disponible très réduit. The invention is particularly advantageous when a car manufacturer requires the attachment of two heat exchangers with each other, with a very limited available space.
L’invention permet d’avoir une seule bride qui sert à deux fonctions à la fois, à savoir la connectique de fluide et le montage mécanique avec‘l’autre échangeur.  The invention makes it possible to have a single flange which serves two functions at the same time, namely the fluid connection and the mechanical assembly with the other exchanger.
Ainsi le montage et le démontage est simplifié car par exemple une seule et même vis est utilisée pour à la fois l’assemblage de la connectique de fluide et le montage mécanique.  Thus assembly and disassembly is simplified because for example a single screw is used for both the assembly of the fluid connection and the mechanical assembly.
Il est également possible de rendre l’ensemble moins cher.  It is also possible to make the whole cheaper.
Dans l‘invention, la bride peut être brasée sur la boite collectrice de l’échangeur. In the invention, the flange can be brazed to the manifold of the exchanger.
En outre, l’invention une fixation plus solide entre les différents éléments. In addition, the invention provides a more solid fixation between the different elements.
Selon l’un des aspects de l’invention, la bride est réalisée d’une seule pièce, par exemple dans un matériau qui contient de l’aluminium.  According to one aspect of the invention, the flange is made in one piece, for example in a material which contains aluminum.
Selon l’un des aspects de l’invention, la portion de montage mécanique comporte un orifice pour recevoir une vis ou un goujon agencé pour permettre l’assemblage de la bride avec l’élément de montage du composant voisin, cet orifice étant notamment taraudé pour recevoir la vis.  According to one aspect of the invention, the mechanical mounting portion includes an orifice for receiving a screw or a stud arranged to allow assembly of the flange with the mounting element of the neighboring component, this orifice being in particular tapped. to receive the screw.
Selon l’un des aspects de l’invention, l’orifice d’entrée ou de sortie de fluide d’une part et l’orifice de montage mécanique d’autre part débouchent sur une face plane commune de la bride.  According to one aspect of the invention, the fluid inlet or outlet opening on the one hand and the mechanical mounting opening on the other hand open onto a common flat face of the flange.
Selon l’un des aspects de l’invention, l’orifice d’entrée ou de sortie de fluide d’une part et l’orifice de montage mécanique d’autre part débouchent sur des faces planes respectives se raccordant entre elles par une marche.  According to one aspect of the invention, the fluid inlet or outlet orifice on the one hand and the mechanical mounting orifice on the other hand open onto respective flat faces which are connected together by a step .
L’invention concerne encore un échangeur thermique notamment pour véhicule automobile comportant au moins une boîte collectrice de fluide, ladite au moins une boîte collectrice comprenant au moins une bride de connexion conforme à ce qui est décrit ci- dessus, cette bride étant notamment fixée sur la boite collectrice par brasage.  The invention also relates to a heat exchanger in particular for a motor vehicle comprising at least one fluid collecting box, said at least one collecting box comprising at least one connection flange in accordance with what is described above, this flange being in particular fixed on the manifold by brazing.
L’invention concerne encore une combinaison de deux échangeurs de chaleur, le premier échangeur étant un échangeur comme précité, le deuxième échangeur étant un composant voisin avec lequel le premier échangeur est assemblé.  The invention also relates to a combination of two heat exchangers, the first exchanger being an exchanger as mentioned above, the second exchanger being a neighboring component with which the first exchanger is assembled.
Selon l’un des aspects de l’invention, la combinaison comporte un élément de montage formé par une patte de fixation, notamment pourvu d’un coude, cet élément de montage étant solidaire du deuxième échangeur, notamment solidaire d’une boite collectrice de ce deuxième échangeur, cet élément de montage étant agencé pour être assemblé sur la portion de montage mécanique de la bride du premier échangeur, l’assemblage étant réalisé notamment à l’aide d’une vis ou d’un goujon qui est introduit dans la portion de montage mécanique de la bride. According to one aspect of the invention, the combination includes an element of mounting formed by a fixing lug, in particular provided with a bend, this mounting element being integral with the second exchanger, in particular integral with a manifold of this second exchanger, this mounting element being arranged to be assembled on the portion of mechanical mounting of the flange of the first exchanger, the assembly being carried out in particular using a screw or a stud which is introduced into the mechanical mounting portion of the flange.
Selon l’un des aspects de l’invention, la patte de fixation est réalisée en matériau aluminium et comporte avantageusement un perçage pour laisser passer la vis ou le goujon. Cette patte de montage est notamment fixée sur la boite collectrice qui lui est associée par brasage.  According to one aspect of the invention, the fixing lug is made of aluminum material and advantageously includes a hole for letting through the screw or the stud. This mounting tab is in particular fixed to the manifold which is associated with it by soldering.
Selon l’un des aspects de l’invention, la combinaison comporte un organe de connexion de fluide agencé pour assemblé sur la bride pour être mis en communication de fluide avec l’orifice d’entrée ou de sortie de fluide de la bride. Cet organe de connexion est notamment réalisé d’un bloc en aluminium.  According to one aspect of the invention, the combination comprises a fluid connection member arranged to be assembled on the flange to be put in fluid communication with the fluid inlet or outlet port of the flange. This connection member is in particular made of an aluminum block.
Selon l’un des aspects de l’invention, ce bloc de connexion comporte un orifice de fluide pour le raccordement de fluide et un évidement pour le passage d’une vis ou un goujon pour permettre l’assemblage de ce bloc de connexion sur la bride. La vis ou le goujon traverse alors cet évidement et le perçage de la patte de montage et l’orifice dans la portion de montage de la bride.  According to one aspect of the invention, this connection block comprises a fluid orifice for the connection of fluid and a recess for the passage of a screw or a stud to allow the assembly of this connection block on the flange. The screw or stud then passes through this recess and the hole in the mounting lug and the hole in the mounting portion of the flange.
Selon l’un des aspects de l’invention, ce bloc de connexion comporte une région de hauteur moindre et une région de hauteur plus grande que la région de hauteur moindre, l’évidement pour le passage de la vis ou du goujon étant formé dans cette région de hauteur moindre, et l’orifice de fluide étant formé sur la région de plus grande hauteur, la région de hauteur moindre formant avec un face plane de la bride un espace pour recevoir la patte de montage. Une marche est présente entre ces deux régions de hauteurs différentes. La patte de connexion et la région de plus grande hauteur forment une surface extérieure plane commune en regarde de la bride.  According to one aspect of the invention, this connection block comprises a region of lesser height and a region of greater height than the region of lesser height, the recess for the passage of the screw or stud being formed in this region of lesser height, and the fluid orifice being formed on the region of greater height, the region of lesser height forming with a flat face of the flange a space for receiving the mounting tab. There is a step between these two regions of different heights. The connecting lug and the region of greatest height form a common flat exterior surface facing the flange.
En variante, la bride comporte une région de hauteur moindre et une région de hauteur plus grande que la région de hauteur moindre, l’orifice pour le passage de la vis ou du goujon étant formé dans cette région de hauteur moindre, et l’orifice de fluide étant formé sur la région de plus grande hauteur, la région de hauteur moindre formant avec un face plane du bloc de connexion un espace pour recevoir la patte de montage. Une marche est présente entre ces deux régions de hauteurs différentes. La patte de connexion et la région de plus grande hauteur forment une surface extérieure plane commune en regarde du bloc de connexion lequel ne présente alors aucune marche pour la patte de montage. As a variant, the flange comprises a region of lesser height and a region of greater height than the region of lesser height, the orifice for the passage of the screw or of the stud being formed in this region of lesser height, and the orifice of fluid being formed on the region of greatest height, the region of least height forming with a flat face of the connection block a space for receiving the mounting lug.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante, donnée à titre d'exemple illustratif et non limitatif, et des dessins annexés parmi lesquels : Other characteristics and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings among which:
- les figures 1 à 4 représentent de façon simplifiée un combinaison d’échangeurs selon un premier exemple de l’invention,  FIGS. 1 to 4 show in a simplified manner a combination of exchangers according to a first example of the invention,
- les figures 5 et 6 représentent un autre exemple de réalisation de l’invention.  - Figures 5 and 6 show another embodiment of the invention.
On a représenté de façon simplifiée sur la figure 1, un échangeur thermique 1, tel qu'un condenseur d'un circuit de climatisation, comprenant un faisceau formé d'une multiplicité de tubes 3, agencés selon une ou plusieurs rangées de tubes 3. There is shown in simplified manner in FIG. 1, a heat exchanger 1, such as a condenser of an air conditioning circuit, comprising a bundle formed of a multiplicity of tubes 3, arranged according to one or more rows of tubes 3.
L'échangeur 1 comporte dans l'exemple illustré deux boîtes collectrices 5 de fluide de façon à permettre l'admission d'un fluide pour circuler dans le faisceau, puis l'évacuation du fluide.  The exchanger 1 comprises in the example illustrated two manifolds 5 of fluid so as to allow the admission of a fluid to circulate in the bundle, then the evacuation of the fluid.
On prévoit à cet effet des brides 7 d'entrée et de sortie du fluide montées selon l'exemple illustré sur une boîte collectrice 5.  Fluid inlet and outlet flanges 7 are provided for this purpose, mounted according to the example illustrated on a manifold 5.
Les brides de connexion 7 sont par exemple en aluminium ou en alliage d'aluminium.  The connection flanges 7 are for example made of aluminum or an aluminum alloy.
Une boîte collectrice 5 peut comporter une première partie formant collecteur 9 pour recevoir les extrémités des tubes 3. La boîte collectrice 5 peut comporter encore un couvercle 11 pour fermer la boîte 5. Le collecteur 9 et le couvercle 11 associé délimitent ainsi une cavité à l'intérieur de laquelle débouchent les extrémités des tubes 3. A manifold 5 may have a first part forming a manifold 9 to receive the ends of the tubes 3. The manifold 5 may also include a cover 11 for closing the box 5. The collector 9 and the associated cover 11 thus delimit a cavity inside which open the ends of the tubes 3.
Le collecteur 9 et le couvercle 11 sont par exemple réalisés en deux parties distinctes.  The collector 9 and the cover 11 are for example made in two separate parts.
Le collecteur 9 présente à titre d'exemple une forme générale sensiblement en « U » avec deux branches latérales.  The collector 9 has by way of example a general shape substantially in a "U" shape with two lateral branches.
À cet effet, le collecteur 9 présente une multiplicité de fentes transversales parallèles les unes aux autres et dont la forme est adaptée à celle des extrémités de tube 3 qui traversent le collecteur 9.  To this end, the manifold 9 has a multiplicity of transverse slots parallel to one another and whose shape is adapted to that of the tube ends 3 which pass through the manifold 9.
Le couvercle 11 présente quant à lui une forme complémentaire du collecteur 9. The cover 11 has a shape complementary to the collector 9.

The connection flange 7 for a heat exchanger manifold, comprises a fluid inlet and / or outlet 15 arranged to be connected to a fluid connection member 20.
Cette bride 7 comporte une portion de montage mécanique 18 agencée pour permettre le montage mécanique sur cette bride 7 d’un élément de montage 30 d’un composant voisin 31.  This flange 7 comprises a mechanical mounting portion 18 arranged to allow mechanical mounting on this flange 7 of a mounting element 30 of a neighboring component 31.
La bride 7 est réalisée d’une seule pièce, par exemple dans un matériau qui contient de l’aluminium.  The flange 7 is made in one piece, for example in a material which contains aluminum.
Comme mieux visible sur la figure 2, la portion de montage mécanique 18 comporte un orifice 19 pour recevoir une vis 22 ou un goujon agencé pour permettre l’assemblage de la bride avec l’élément de montage du composant voisin 31, cet orifice étant notamment taraudé pour recevoir la vis 22.  As best seen in Figure 2, the mechanical mounting portion 18 has an orifice 19 for receiving a screw 22 or a stud arranged to allow assembly of the flange with the mounting element of the neighboring component 31, this orifice being in particular tapped to receive screw 22.
L’orifice d’entrée ou de sortie de fluide 15 d’une part et l’orifice de montage mécanique 19 d’autre part débouchent sur une face plane commune 24 de la bride 7.  The fluid inlet or outlet orifice 15 on the one hand and the mechanical mounting orifice 19 on the other hand open onto a common flat face 24 of the flange 7.
En variante, comme illustré sur les figures 5 et 6, l’orifice d’entrée ou de sortie 15 de fluide d’une part et l’orifice de montage mécanique 18 d’autre part débouchent sur des faces planes respectives 25 et 26 se raccordant entre elles par une marche 27.  As a variant, as illustrated in FIGS. 5 and 6, the fluid inlet or outlet port 15 on the one hand and the mechanical mounting orifice 18 on the other hand open onto respective flat faces 25 and 26 connecting together with a step 27.
Ainsi, la bride comporte une région de hauteur moindre 52 et une région de hauteur plus grande 53 que la région de hauteur moindre, l’orifice 18 pour le passage de la vis ou du goujon étant formé dans cette région de hauteur moindre 52, et l’orifice de fluide 15 étant formé sur la région de plus grande hauteur 53, la région de hauteur moindre formant avec un face plane du bloc de connexion un espace pour recevoir la patte de montage. Une marche 27 est présente entre ces deux régions de hauteurs différentes. La patte de connexion et la région de plus grande hauteur forment une surface extérieure plane commune en regarde du bloc de connexion lequel ne présente alors aucune marche pour la patte de montage. Thus, the flange has a region of lesser height 52 and a region of greater height 53 than the region of lesser height, the orifice 18 for the passage of the screw or stud being formed in this region of lesser height 52, and the fluid orifice 15 being formed on the region of greater height 53, the region of lesser height forming with a flat face of the connection block a space for receive the mounting bracket. A step 27 is present between these two regions of different heights. The connection lug and the region of greatest height form a common flat outer surface facing the connection block which then has no steps for the mounting lug.
L’invention concerne en outre une combinaison 50 de deux échangeurs de chaleur 1 et 31, qui comporte l’élément de montage 30 formé par une patte de fixation, pourvu d’un coude 33, cet élément de montage 30 étant solidaire du deuxième échangeur 31, notamment solidaire d’une boite collectrice 37 de ce deuxième échangeur 31, cet élément de montage étant agencé pour être assemblé sur la portion de montage mécanique 18 de la bride 7 du premier échangeur 1, l’assemblage étant réalisé notamment à l’aide d’une vis 22 qui est introduit dans la portion de montage mécanique 18 de la bride.  The invention further relates to a combination 50 of two heat exchangers 1 and 31, which comprises the mounting element 30 formed by a fixing lug, provided with an elbow 33, this mounting element 30 being integral with the second exchanger 31, in particular integral with a manifold 37 of this second exchanger 31, this mounting element being arranged to be assembled on the mechanical mounting portion 18 of the flange 7 of the first exchanger 1, the assembly being carried out in particular at using a screw 22 which is introduced into the mechanical mounting portion 18 of the flange.
La patte de fixation 30 est réalisée en matériau aluminium ou alliage d’aluminium et comporte avantageusement un perçage 39 pour laisser passer la vis 22, comme visible sur la figure 2. Cette patte de montage 30 est notamment fixée sur la boite collectrice 37 qui lui est associée par brasage.  The fixing lug 30 is made of aluminum or aluminum alloy material and advantageously includes a hole 39 to allow the screw 22 to pass, as visible in FIG. 2. This mounting lug 30 is notably fixed on the manifold 37 which is associated by soldering.
La combinaison 50 comporte un organe de connexion de fluide 20 agencé pour assemblé sur la bride 7 pour être mis en communication de fluide avec l’orifice d’entrée ou de sortie de fluide de la bride. Cet organe de connexion est notamment réalisé d’un bloc 20 en aluminium.  The combination 50 comprises a fluid connection member 20 arranged to be assembled on the flange 7 to be placed in fluid communication with the fluid inlet or outlet port of the flange. This connection member is in particular made of a block 20 of aluminum.
Ce bloc de connexion 20 comporte un orifice de fluide 40 pour le raccordement de fluide et un évidement 41 pour le passage d’une vis 22 pour permettre l’assemblage de ce bloc 20 de connexion sur la bride 7. La vis 22 traverse alors cet évidement 41 et le perçage 398 de la patte de montage et l’orifice 19 dans la portion de montage de la bride This connection block 20 comprises a fluid orifice 40 for the fluid connection and a recess 41 for the passage of a screw 22 to allow the assembly of this connection block 20 on the flange 7. The screw 22 then passes through this recess 41 and the hole 398 in the mounting tab and the orifice 19 in the mounting portion of the flange
7. 7.
Ce bloc de connexion 20 comporte une région de hauteur moindre 62 et une région 63 de hauteur plus grande que la région de hauteur moindre, l’évidement 41 pour le passage de la vis ou du goujon étant formé dans cette région de hauteur moindre, 62 et G orifice de fluide 40 étant formé sur la région de plus grande hauteur 63, la région de hauteur moindre formant avec une face plane de la bride un espace 55 pour recevoir la patte de montage 30. Une marche 67 est présente entre ces deux régions 62 et 63 de hauteurs différentes. La patte de connexion 30 et la région de plus grande hauteur forment une surface extérieure plane commune en regarde de la bride, comme on peut le voir les figures 3 et 4. This connection block 20 comprises a region of lesser height 62 and a region 63 of greater height than the region of lesser height, the recess 41 for the passage of the screw or stud being formed in this region of lesser height, 62 and G orifice of fluid 40 being formed on the region of greatest height 63, the region of least height forming with a flat face of the flange a space 55 to receive the mounting tab 30. A step 67 is present between these two regions 62 and 63 of different heights. The connection tab 30 and the region of greatest height form a common flat exterior surface facing the flange, as can be seen in FIGS. 3 and 4.
Selon l’un des aspects de l’invention, la patte de montage est réalisée en aluminium ou alliage d’aluminium. According to one aspect of the invention, the mounting lug is made of aluminum or aluminum alloy.
