Description

Condenseur de climatisation, notamment pour un véhicule automobile, comportant une embase raccordée à une boîte collectriceAir conditioning condenser, in particular for a motor vehicle, comprising a base connected to a manifold
L'invention concerne un condenseur, notamment pour un circuit de climatisation de l'habitacle d'un véhicule automobile.The invention relates to a condenser, in particular for an air conditioning circuit for the passenger compartment of a motor vehicle.
Elle concerne plus particulièrement un condenseur comprenant une boîte collectrice, une embase raccordée à la boîte collectrice, un réservoir propre à être monté sur l'embase pour l'accumulation et le traitement d'un fluide frigorigène, ce réservoir logeant un ensemble de filtration et de déshydratation du fluide frigorigène.It relates more particularly to a condenser comprising a manifold, a base connected to the manifold, a tank capable of being mounted on the base for the accumulation and treatment of a refrigerant, this tank housing a filtration assembly and dehydration of the refrigerant.
On connaît déjà, d'après FR 2 754 887, un condenseur de ce ..type comprenant un réservoir interposé entre une partie amont et une partie aval du condenseur. Un réservoir intermédiaire se fixe de manière amovible sur une embase solidaire de la boîte collectrice, traversée par deux conduites de liaison. Ce réservoir est muni à son extrémité inférieure d'un embout qui est vissé sur l'embase au moyen d'un pas de vis. L'embase est réalisée sous la forme d'une pièce moulée ou atricée, en alliage métallique, avantageusement en alliage à base d'aluminium. L'embase est brasée sur la boîte collectrice en même temps que le faisceau du condenseur.Already known from FR 2 754 887, a condenser of this type comprising a reservoir interposed between an upstream part and a downstream part of the condenser. An intermediate tank is removably fixed to a base secured to the manifold, crossed by two connecting pipes. This tank is provided at its lower end with a nozzle which is screwed onto the base by means of a screw thread. The base is produced in the form of a molded or atricated piece, of a metal alloy, advantageously of an aluminum-based alloy. The base is brazed to the manifold at the same time as the condenser harness.
Une embase de ce type est une pièce complexe a réaliser. Sa fabrication nécessite de multiples opérations successives. Elle doit être matricée, puis découpée, traitée thermiquement et enfin usinée. L'usinage nécessite de multiples reprises (perçage, tournage pour de multiples diamètres, réalisation de pas de vis et de pastilles pour obturer les contre-perçages).A base of this type is a complex part to produce. Its manufacture requires multiple successive operations. It must be stamped, then cut, heat treated and finally machined. Machining requires multiple repetitions (drilling, turning for multiple diameters, production of threads and pads to close the counter-holes).
Par ailleurs, le réservoir est constitué de trois parties assemblées, à savoir un embout, un corps et une tête. La tête du réservoir est complexe à réaliser en usinage. Elle nécessite une gamme de réalisations spécifiques avant son assemblage sur le corps du réservoir. Cet enchaînement des opérations de montage requiert une soudure TIG de la tête sur le réservoir. Cette soudure engendre des déformations et des défauts géométriques qui peuvent poser des problèmes de coaxialité et des difficultés au vissage du réservoir sur l'embase.Furthermore, the reservoir consists of three assembled parts, namely a nozzle, a body and a head. The head of the tank is complex to perform in machining. It requires a range of specific embodiments before it is assembled on the body of the tank. This sequence of assembly operations requires TIG welding of the head on the tank. This welding generates deformations and geometric defects which can cause coaxiality problems and difficulties in screwing the reservoir onto the base.
Enfin, les fonctions de filtration et de déshydratation n'occupent pas le volume interne du réservoir de manière optimale.Finally, the filtration and dehydration functions do not occupy the internal volume of the tank optimally.
La présente invention a pour but de surmonter les inconvénients précités. Elle propose à cet effet un condenseur du type défini en introduction, dans lequel l'embase est obtenue par découpe d'un tronçon d'un profilé extrudé.The present invention aims to overcome the aforementioned drawbacks. To this end, it offers a condenser of the type defined in the introduction, in which the base is obtained by cutting a section of an extruded profile.
Avantageusement, le profilé extrudé comporte une excroissance qui constitue, après découpage d'un tronçon, une patte de fixation pour la fixation de l'embase sur la boîte collectrice.Advantageously, the extruded profile has a projection which constitutes, after cutting a section, a fixing lug for fixing the base on the manifold.
Ainsi, l'embase est une pièce simple dont le diamètre extérieur est brut et qui nécessite seulement le perçage d'un ou deux orifices pour le passage des conduites de liaison et, d'autre part, d'un lamage destiné à recevoir un bouchon d'obturation.Thus, the base is a simple piece whose outside diameter is gross and which only requires the drilling of one or two orifices for the passage of the connecting pipes and, on the other hand, a countersink intended to receive a plug. shutter.

Sur ces figures :Other characteristics and advantages of the present invention will appear on reading the following description of an exemplary embodiment with reference to the appended figures. In these figures:

Le condenseur représenté dans son ensemble en vue éclatée sur la Figure 1 comprend un bloc d'échange de chaleur désigné par la référence générale 2, et un ensemble de réservoir 4 relié hydrauliquement au bloc d'échange de chaleur 2 par l'intermédiaire d'une embase 6.The condenser shown as a whole in exploded view in FIG. 1 comprises a heat exchange block designated by the general reference 2, and a reservoir assembly 4 hydraulically connected to the heat exchange block 2 by means of a base 6.
Le bloc d'échange de chaleur comprend deux boîtes collectrices 8 et 10, allongées verticalement et espacées l'une de l'autre selon une direction horizontale, reliées entre elles par une multiplicité de tubes de circulation de fluide horizontaux 12. Chaque boîte collectrice 8, 10 est divisée en différentes chambres par des cloisons horizontales (non représentées), de manière que le fluide de cycle frigorigène circule dans les tubes 12, alternativement d'une chambre de la boîte 8 à une chambre de la boîte 10 et inversement, depuis la chambre supérieure de la boîte 8 qui communique avec une tubulure d'entrée 14, jusqu'à la chambre inférieure de cette même boîte collectrice 8, raccordée à la valve de détente par l'intermédiaire d'une tubulure de sortie 16.The heat exchange block comprises two manifolds 8 and 10, elongated vertically and spaced from one another in a horizontal direction, connected together by a multiplicity of horizontal fluid circulation tubes 12. Each manifold 8 , 10 is divided into different chambers by horizontal partitions (not shown), so that the refrigerant cycle circulates in the tubes 12, alternately from a chamber of the box 8 to a chamber of the box 10 and vice versa, from the upper chamber of the box 8 which communicates with an inlet pipe 14, to the lower chamber of this same manifold 8, connected to the expansion valve via '' an outlet pipe 16.
Une cloison intermédiaire (non représentée) de la boîte collectrice 10 sépare l'une de l'autre des chambres qui communiquent entre elles exclusivement par l'intermédiaire de l'ensemble de réservoir 4. A cette fin, la boîte collectrice 10 comporte deux ouvertures espacées (non représentées) dans lesquelles sont introduites les extrémités des conduites de liaison 20 et 22 de l'embase 6.An intermediate partition (not shown) of the manifold 10 separates one from the other of the chambers which communicate with each other exclusively via the tank assembly 4. To this end, the manifold 10 has two openings spaced (not shown) into which are inserted the ends of the connecting pipes 20 and 22 of the base 6.
Un ensemble de réservoir, désigné par la référence générale 4, est vissé sur l'embase 6. L'ensemble de réservoir est essentiellement constitué de deux parties, à savoir un réservoir 24 et un ensemble 26 de filtration et de déshydratation. Le réservoir 24 est constitué d'un corps 30 raccordé à un embout 32 qui se visse sur l'embase 6. Le corps 30 comporte une partie cylindrique 34 de diamètre sensiblement constant qui occupe la plus grande partie de sa hauteur et un col rétréci 36 situé à la partie supérieure du corps. Lorsque l'ensemble de réservoir 4 est assemblé, l'ensemble de filtration et de déshydratation 26 est logé dans le réservoir 24, l'extrémité inférieure de l'ensemble 26 étant reçue dans l'embase 6.A reservoir assembly, designated by the general reference 4, is screwed onto the base 6. The reservoir assembly essentially consists of two parts, namely a reservoir 24 and a filtration and dehydration assembly 26. The reservoir 24 consists of a body 30 connected to a nozzle 32 which screws onto the base 6. The body 30 comprises a cylindrical part 34 of substantially constant diameter which occupies most of its height and a narrowed neck 36 located at the top of the body. When the reservoir assembly 4 is assembled, the filtration and dehydration assembly 26 is housed in the reservoir 24, the lower end of the assembly 26 being received in the base 6.
Comme on peut le voir sur la Figure 2, et mieux encore sur la Figure 4, chacune des boîtes collectrices 8 et 10 est formée par l'assemblage de deux demi-coquilles 40 et 42. Les demi- coquilles 40 de chacune des deux boîtes collectrices reçoivent les extrémités des tubes 12. La demi-coquille 42 de la boîte collectrice 10 comporte deux ouvertures espacées dans lesquelles sont introduites les extrémités des conduites de liaison 20 et 22 de l'embase 6. On a représenté sur la Figure 3 une vue en coupe selon la ligne III-III de l'ensemble de réservoir 4 assemblé. L'embout 32 comporte une portée cylindrique 44 filetée, vissée dans l'embase 6. Le diamètre cylindrique 44 se prolonge par une section 46 de plus petit diamètre comportant deux joints d'etancheité toriques 48 qui permettent de réaliser une étanchéité statique au fluide réfrigérant entre le diamètre intérieur de l'embase 6 et la portée 46 de l'embout 32.As can be seen in Figure 2, and better still in Figure 4, each of the manifolds 8 and 10 is formed by the assembly of two half-shells 40 and 42. The half-shells 40 of each of the two boxes manifolds receive the ends of the tubes 12. The half-shell 42 of the manifold 10 has two spaced openings into which the ends of the connecting pipes 20 and 22 of the base 6 are introduced. There is shown in Figure 3 a sectional view along line III-III of the assembled tank assembly 4. The end piece 32 has a cylindrical bearing surface 44 threaded, screwed into the base 6. The cylindrical diameter 44 is extended by a section 46 of smaller diameter comprising two O-ring seals 48 which make it possible to produce a static seal against the coolant. between the internal diameter of the base 6 and the bearing surface 46 of the end piece 32.
L'embout 32 est solidarisé au corps 30, par exemple par collage ou par soudage. Comme on peut le constater, ce corps ne comporte que des formes géométriques simples. Il est constitué d'une partie cylindrique 34 qui occupe la plus grande partie de sa hauteur et d'un col rétréci de plus petit diamètre qui permet la fixation, par exemple au moyen d'un collier de serrage, de la partie supérieure du réservoir sur le bloc d'échange de chaleur 2. A la partie supérieure du corps 30, on trouve une empreinte creuse hexagonale 50 qui permet l'introduction d'un outil de vissage pour visser le réservoir sur l'embase 6. Compte tenu de sa géométrie simple, le corps 30 peut être réalisé en un nombre réduit d'étapes d'emboutissage. On évite ainsi d'avoir à usiner et à assembler par soudage une tête séparée.The end piece 32 is secured to the body 30, for example by gluing or by welding. As you can see, this body has only simple geometric shapes. It consists of a cylindrical part 34 which occupies most of its height and a narrowed neck of smaller diameter which allows the fixing, for example by means of a clamp, of the upper part of the tank. on the heat exchange block 2. At the upper part of the body 30, there is a hexagonal hollow imprint 50 which allows the introduction of a screwing tool for screwing the reservoir onto the base 6. Given its simple geometry, the body 30 can be produced in a reduced number of stamping steps. This avoids having to machine and assemble by welding a separate head.
La Figure 4 permet d'apprécier la section du profilé extrudé à partir duquel l'embase est tronçonnée. Ce profilé comporte une section tubulaire 60 ayant un diamètre extérieur 62 et un diamètre intérieur 64. Le profilé comporte également une excroissance 66 présentant sensiblement la forme d'un voile épais tangent au profil tubulaire 60. Une conduite d'entrée 68 et une conduite de sortie (non représentée) sont percées dans le voile 66. Ces deux conduites débouchent dans l'espace intérieur défini par le diamètre 64. Les conduites de liaison se terminent par les deux extrémités 20 et 22 qui s'engagent dans les ouvertures correspondantes de la demi-coquille 42 de la boîte collectrice 10. Comme on peut le voir sur la Figure 3, l'ensemble de filtration et de déshydratation 26 est logé à l'intérieur du réservoir 4. Son extrémité inférieure traverse l'embout 32 et elle vient s'appuyer sur un bouchon de fermeture 80 serti et brasé sur le tronçon profilé constituant l'embase. Des ouïes 82 sont prévues à la partie inférieure de l'ensemble de filtration et de déshydratation pour permettre l'entrée du fluide réfrigérant. La partie inférieure de l'ensemble de filtration et de déshydratation comporte encore une lèvre d'etancheité 84 qui vient s'appliquer contre le diamètre intérieur 64 du profilé cylindrique 60. La lèvre 84 réalise une étanchéité au fluide de cycle frigorigène et oblige ce dernier à traverser l'ensemble filtrant. La partie supérieure de l'ensemble de filtration et de déshydratation est fermée par un bouchon 86 appliqué élastiquement contre la tête du corps 30.Figure 4 shows the cross-section of the extruded profile from which the base is cut. This profile has a tubular section 60 having an outside diameter 62 and an inside diameter 64. The profile also has a protrusion 66 having substantially the shape of a thick veil tangent to the tubular profile 60. An inlet pipe 68 and a outlet (not shown) are drilled in the web 66. These two pipes open into the interior space defined by the diameter 64. The connecting pipes end at the two ends 20 and 22 which engage in the corresponding openings of the half-shell 42 of the manifold 10. As can be seen in Figure 3, the filtration and dehydration assembly 26 is housed inside the reservoir 4. Its lower end passes through the end piece 32 and it comes to rest on a crimped closure cap 80 and brazed on the profiled section constituting the base. Louvers 82 are provided in the lower part of the filtration and dehydration assembly to allow the entry of the coolant. The lower part of the filtration and dehydration assembly also includes a sealing lip 84 which is applied against the internal diameter 64 of the cylindrical profile 60. The lip 84 provides a seal against the refrigerant cycle fluid and forces the latter through the filter assembly. The upper part of the filtration and dehydration assembly is closed by a plug 86 applied elastically against the head of the body 30.
Une portion du volume interne de l'ensemble de filtration et de déshydratation 26 est utilisée pour stocker du fluide réfrigérant. Ceci augmente la capacité de volume utile du condenseur sans augmenter son encombrement extérieur. Cet encombrement peut même être diminué dans certains cas . L'ensemble de filtration et de déshydratation peut être adapté à tous les cahiers des charges. En effet, la masse de dessiccant est ajustable en fonction des besoins. A portion of the internal volume of the filtration and dehydration assembly 26 is used to store refrigerant fluid. This increases the useful volume capacity of the condenser without increasing its external dimensions. This size can even be reduced in certain cases. The filtration and dehydration system can be adapted to all specifications. Indeed, the mass of desiccant is adjustable according to the needs.
