Description

L'invention concerne un condenseur propre à faire partie d'un circuit de réfrigération, en particulier d'une installation de climatisation de véhicule automobile.The invention relates to a condenser capable of being part of a refrigeration circuit, in particular of an installation motor vehicle air conditioning.

Elle concerne plus particulièrement un condenseur propre à être parcouru par un fluide frigorigène et comprenant un réservoir amovible raccordé à une boíte collectrice du condenseur et propre à être traversé par le fluide frigorigène.It relates more particularly to a condenser specific to be traversed by a refrigerant and comprising a removable tank connected to a manifold condenser and suitable for the refrigerant to pass through.

Dans un circuit de réfrigération de ce type, le fluide frigorigène est envoyé, en phase vapeur surchauffée, sous l'action d'un compresseur vers le condenseur, dans lequel il est successivement refroidi ou "désurchauffé", condensé en une phase liquide chaude, puis "sous-refroidi" en une phase liquide froide.In a refrigeration circuit of this type, the fluid refrigerant is sent, in superheated vapor phase, under the action of a compressor towards the condenser, in which it is successively cooled or "desuperheated", condensed into a hot liquid phase, then "sub-cooled" in one phase cold liquid.

Le fluide frigorigène ainsi condensé et refroidi est ensuite envoyé, via un détendeur, vers un évaporateur où il échange de la chaleur avec un flux d'air à envoyer dans l'habitacle du véhicule. Dans cet évaporateur, le fluide frigorigène est transformé en phase vapeur, tandis que le flux d'air est refroidi, ce qui permet de fournir de l'air climatisé. Le fluide frigorigène en phase vapeur quitte ensuite l'évaporateur pour gagner le compresseur, et ainsi de suite.The refrigerant thus condensed and cooled is then sent, via a pressure reducer, to an evaporator where it exchanges heat with an air flow to send into the passenger compartment of the vehicle. In this evaporator, the refrigerant is transformed into vapor phase, while the air flow is cooled, which provides air conditioning. The refrigerant in vapor phase then leaves the evaporator to win the compressor, and so on.

Un condenseur de ce type comprend habituellement un faisceau de tubes monté entre deux boítes collectrices, en sorte que la condensation puis le refroidissement du fluide frigorigène condensé s'effectuent au fur et à mesure de la progression de ce dernier dans les tubes du faisceau.A condenser of this type usually includes a bundle of tubes mounted between two manifolds, so that condensation then cooling of the refrigerant condensed take place as the progression of the latter in the bundle tubes.

On connaít déjà, d'après EP-A-0 480 330, un condenseur de ce type dans lequel le réservoir est amovible et est en outre relié en un point intermédiaire du faisceau situé entre une première partie du faisceau où le fluide frigorigène est condensé, et une seconde partie du faisceau où le fluide frigorigène condensé est sous-refroidi.We already know, from EP-A-0 480 330, a condenser of this type in which the tank is removable and is further connected at an intermediate point of the beam located between a first part of the bundle where the refrigerant is condensed, and a second part of the beam where the fluid condensed refrigerant is sub-cooled.

Ce réservoir est prévu pour recueillir une partie du fluide frigorigène condensé et chaud pour la sous-refroidir et assurer la séparation des phases liquide et vapeur du fluide frigorigène, lequel est ensuite sous-refroidi davantage dans la seconde partie du faisceau.This tank is designed to collect part of the fluid condensed and hot refrigerant to sub-cool it and ensuring the separation of the liquid and vapor phases from the fluid refrigerant, which is then further sub-cooled in the second part of the beam.

En outre, ce réservoir contient habituellement un produit desséchant pour déshydrater le fluide frigorigène.In addition, this tank usually contains a product drying to dehydrate the refrigerant.

Dans le condenseur connu par la publication EP-A-0 480 330, le réservoir comporte une partie réceptrice qui est propre à coopérer avec une partie adaptatrice prévue sur la boíte collectrice du condenseur, ces deux parties étant assujetties par un moyen de fixation du type vis.In the condenser known from the publication EP-A-0 480 330, the reservoir has a receiving part which is suitable for cooperate with an adapter part provided on the box condenser collector, these two parts being subject by a screw-type fixing means.

Il en résulte l'inconvénient que, dans le cas où le réservoir doit être remplacé, il faut remplacer tout l'ensemble constitué par le réservoir proprement dit et la partie réceptrice dont il est solidaire.This results in the disadvantage that, in the case where the tank must be replaced, the whole assembly must be replaced consisting of the tank itself and the part receptor with which he is attached.

Par ailleurs, ce réservoir connu est particulièrement encombrant.Furthermore, this known reservoir is particularly bulky.

Il faut souligner également que, dans ce condenseur connu, les possibilités d'implantation et d'orientation du réservoir sont limitées.It should also be emphasized that, in this known condenser, the possibilities of installation and orientation of the reservoir are limited.

Il en résulte qu'un même condenseur ne peut être utilisé, à chaque fois, que pour un type de véhicule bien défini.As a result, the same condenser cannot be used, except each time, only for a well-defined type of vehicle.

L'invention a notamment pour but de surmonter les inconvénients précités.The object of the invention is in particular to overcome the drawbacks cited above.

Elle propose à cet effet un condenseur du type défini en introduction, dans lequel le réservoir est réalisé sous la forme d'une cartouche remplaçable munie d'un raccord propre à coopérer avec une embase de forme conjuguée qui est solidaire de la boíte collectrice et reliée à cette dernière par l'intermédiaire d'une tubulure d'entrée et d'une tubulure de sortie pour le fluide frigorigène.To this end, it proposes a condenser of the type defined in introduction, in which the reservoir is produced under the replaceable cartridge shape with clean fitting to cooperate with a base of conjugate form which is secured to and connected to the manifold via inlet tubing and tubing outlet for the refrigerant.

Ainsi, dans le cas où le réservoir doit être remplacé, il suffit simplement d'enlever la cartouche et de la remplacer par une autre cartouche, sans intervenir sur l'embase qui reste toujours solidaire de la boíte collectrice.So, in case the tank needs to be replaced, it just remove the cartridge and replace it by another cartridge, without intervening on the base which always remains attached to the manifold.

Par ailleurs, comme cette embase est reliée à la boíte collectrice par l'intermédiaire de deux tubulures, il est possible de faire déboucher ces deux tubulures en des endroits choisis de la boíte collectrice et de donner en outre une orientation choisie à l'embase, donc à la cartouche.Furthermore, as this base is connected to the box collector by means of two pipes, it is possible to unblock these two tubes in selected locations of the manifold and give in in addition to an orientation chosen at the base, therefore at the cartridge.

Il en résulte qu'un même condenseur peut offrir une multiplicité de positions d'implantation du réservoir.As a result, the same condenser can offer a multiplicity tank installation positions.

Selon une autre caractéristique de l'invention, le raccord de la cartouche comprend un embout axial creux propre à être reçu dans un logement axial de l'embase.According to another characteristic of the invention, the connection of the cartridge includes a hollow axial tip suitable for being received in an axial housing of the base.

De façon avantageuse, cet embout axial dépend d'un fond perforé propre à être reçu dans un logement annulaire de l'embase qui entoure le logement axial de l'embase.Advantageously, this axial end piece depends on a bottom perforated suitable for being received in an annular housing of the base which surrounds the axial housing of the base.

Selon une autre caractéristique de l'invention, le logement annulaire et le logement axial de l'embase communiquent l'un avec la conduite d'entrée et l'autre avec la conduite de sortie du fluide frigorigène.According to another characteristic of the invention, the housing ring and the axial housing of the base communicate with one with the inlet line and the other with the line refrigerant outlet.

Ainsi, lorsque la cartouche est mise en place dans l'embase, le fluide frigorigène peut traverser la cartouche.So when the cartridge is placed in the base, the refrigerant can pass through the cartridge.

Avantageusement, le logement annulaire et le logement axial de l'embase communiquent respectivement avec la conduite d'entrée et la conduite de sortie. Il en résulte que le fluide frigorigène pénètre dans le logement annulaire, passe ensuite à l'intérieur de la cartouche au travers du fond perforé et quitte enfin la cartouche par l'embout axial creux.Advantageously, the annular housing and the axial housing of the manifold communicate respectively with the pipe inlet and outlet pipe. As a result, the refrigerant enters the annular housing, passes then inside the cartridge through the bottom perforated and finally leaves the cartridge through the axial tip hollow.

Dans une forme de réalisation préférée de l'invention, l'embout axial de la cartouche comporte un filetage externe propre à coopérer avec un filetage interne du logement axial de l'embase, ce qui permet une fixation de la cartouche par un simple vissage.In a preferred embodiment of the invention, the axial tip of the cartridge has an external thread suitable for cooperating with an internal thread of the axial housing of the base, which allows the cartridge to be fixed by a simple screwing.

Bien entendu, d'autres modes de fixation de l'embout sont envisageables.Of course, other methods of attaching the endpiece are possible.

Dans une forme de réalisation, la tubulure d'entrée et la tubulure de sortie sont réalisées d'une seule pièce avec l'embase. Dans une autre forme, la tubulure d'entrée et la tubulure de sortie sont reliées par brasage à l'embase.In one embodiment, the inlet tubing and the outlet pipes are made in one piece with the base. In another form, the inlet tubing and the outlet pipes are connected by brazing to the base.

Avantageusement, le raccord de la cartouche comporte une paroi cylindrique circulaire extérieure propre à être reçue dans une paroi cylindrique circulaire intérieure de l'embase, avec interposition d'au moins un joint annulaire d'étanchéité.Advantageously, the connector of the cartridge comprises a external circular cylindrical wall suitable for receiving in an inner circular cylindrical wall of the base, with interposition of at least one annular seal.

La cartouche peut revêtir différentes formes.The cartridge can take different forms.

De façon avantageuse, elle comprend un tube cylindrique dont une extrémité est assemblée au raccord et dont une autre extrémité est assemblée à un bouchon.Advantageously, it comprises a cylindrical tube whose one end is assembled to the fitting and another end is assembled with a plug.

Avantageusement, le tube, le raccord et le bouchon sont assemblés entre eux par brasage.Advantageously, the tube, the fitting and the plug are joined together by brazing.

Selon une autre caractéristique de l'invention, la cartouche contient un produit desséchant. According to another characteristic of the invention, the cartridge contains a drying agent.

L'invention s'applique en particulier à un condenseur dans lequel la boíte collectrice est reliée a un faisceau de tubes. De façon avantageuse, la tubulure d'entrée et la tubulure de sortie débouchent dans deux compartiments adjacents de la boíte collectrice qui communiquent respectivement avec une partie du faisceau servant à la condensation du fluide frigorigène et une Partie du faisceau servant au sous-refroidissement du fluide frigorigène condensé.The invention applies in particular to a condenser in which the manifold is connected to a beam of tubes. Advantageously, the inlet tubing and the outlet tubing open into two compartments adjacent to the manifold which communicate respectively with part of the beam used for condensation refrigerant and part of the harness used for sub-cooling of the condensed refrigerant.

Selon encore une autre caractéristique de l'invention, l'embase et la cartouche s'étendent suivant un axe directeur qui peut être placé avec un angle et une position choisis par rapport à la boíte collectrice.According to yet another characteristic of the invention, the base and the cartridge extend along a steering axis which can be placed at an angle and position chosen by compared to the manifold.

Dans la description qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :

  • la figure 1 est une vue en coupe partielle d'un condenseur équipé d'un réservoir amovible selon une première forme de réalisation de l'invention;
  • la figure 2 est une représentation schématique du condenseur et du réservoir de la figure 1 montrant les différentes positions d'implantation du réservoir; et
  • la figure 3 est une vue analogue à celle de la figure 1 dans une autre forme de réalisation.
In the description which follows, given solely by way of example, reference is made to the appended drawings, in which:
  • Figure 1 is a partial sectional view of a condenser equipped with a removable tank according to a first embodiment of the invention;
  • Figure 2 is a schematic representation of the condenser and the tank of Figure 1 showing the different positions of installation of the tank; and
  • Figure 3 is a view similar to that of Figure 1 in another embodiment.

On se réfère tout d'abord à la figure 1 qui représente un condenseur propre à faire partie d'une installation de climatisation pour véhicule automobile.We first refer to Figure 1 which represents a clean condenser to be part of an installation of air conditioning for a motor vehicle.

Le condenseur comprend un faisceau 10 formé d'une multiplicité de tubes plats 12 entre lesquels sont placés des intercalaires 14, de forme générale ondulée, formant ailettes d'échange de chaleur. The condenser comprises a beam 10 formed of a multiplicity flat tubes 12 between which are placed spacers 14, generally wavy, forming fins heat exchange.

Le faisceau 10 est monté entre deux boítes collectrices 16 et 18 de forme tubulaire, à section circulaire, et d'axes parallèles, selon une technologie bien connue.The bundle 10 is mounted between two manifolds 16 and 18 of tubular shape, circular section, and axes parallel, according to a well known technology.

La boíte collectrice 16 est munie notamment d'une cloison interne 20 et d'une cloison d'extrémité 22, ce qui permet de définir un compartiment supérieur 24 et un compartiment inférieur 26.The manifold 16 is provided in particular with a partition internal 20 and an end partition 22, which allows define an upper compartment 24 and a compartment lower 26.

Le condenseur est propre a être parcouru par un fluide frigorigène selon une circulation multipasses, comme représenté par les flèches. Ainsi, le fluide frigorigène circule en particulier dans une première partie P1 (ou partie amont) du faisceau dans laquelle le fluide frigorigène arrivant en phase vapeur surchauffée est successivement refroidi ou "désurchauffé" et condensé.The condenser is capable of being traversed by a fluid refrigerant in a multi-pass circulation, as shown by the arrows. Thus, the refrigerant circulates in particular in a first part P1 (or upstream part) of the bundle in which the refrigerant arriving in superheated vapor phase is successively cooled or "desuperheated" and condensed.

Ensuite, le fluide frigorigène préalablement condensé circule dans une dernière partie P2 du faisceau (partie aval) dans laquelle le fluide frigorigène condensé est sous-refroidi.Then, the previously condensed refrigerant circulates in a last part P2 of the beam (downstream part) in which the condensed refrigerant is sub-cooled.

Le condenseur comprend en outre un réservoir 28 qui communique avec le compartiment supérieur 24 et le compartiment inférieur 26 de la boíte collectrice 16 et qui est destiné à être parcouru par le fluide frigorigène.The condenser further comprises a reservoir 28 which communicates with upper compartment 24 and compartment lower 26 of the manifold 16 and which is intended for be traversed by the refrigerant.

La cartouche amovible 28 est reçue dans une embase 30 comportant un corps 32 ayant une forme générale de révolution par rapport à un axe XX et deux tubulures 34 et 36 qui s'étendent chacune dans une direction sensiblement radiale par rapport à l'axe XX. La tubulure 34 débouche dans le compartiment supérieur 24 et constitue une tubulure d'entrée pour le fluide frigorigène, tandis que la tubulure 36 débouche dans le compartiment inférieur 26 et constitue une tubulure de sortie pour le fluide frigorigène.The removable cartridge 28 is received in a base 30 comprising a body 32 having a general shape of revolution relative to an axis XX and two pipes 34 and 36 which each extend in a substantially radial direction with respect to the XX axis. The tubing 34 opens into the upper compartment 24 and constitutes an inlet pipe for refrigerant, while tubing 36 opens into the lower compartment 26 and constitutes a outlet pipe for the refrigerant.

La cartouche 28 comprend essentiellement trois parties : un raccord 38 propre à coopérer avec l'embase 30, un tube 40 dont une extrémité est assemblée au raccord 38, ainsi qu'un bouchon 42 qui est assemblé à l'autre extrémité du tube 40.The cartridge 28 essentially comprises three parts: a fitting 38 suitable for cooperating with the base 30, a tube 40 one end of which is assembled to fitting 38, as well as a plug 42 which is assembled at the other end of the tube 40.

Avantageusement, le raccord 38, le tube 40 et le bouchon 42 sont des pièces métalliques, par exemple en alliages a base d' aluminium, et sont assemblées entre elles par brasage.Advantageously, the connector 38, the tube 40 and the plug 42 are metallic parts, for example made from base alloys aluminum, and are joined together by brazing.

Le bouchon 42 se termine par une tête 44 qui constitue un organe de préhension et éventuellement de serrage ou de desserrage pour la cartouche. Bien que le bouchon 42 soit avantageusement assemblé de façon définitive au tube 40, il pourrait être envisagé, dans une variante, de pouvoir le désolidariser par rapport au tube 40.The plug 42 ends with a head 44 which constitutes a gripping and possibly clamping or loosening for the cartridge. Although plug 42 is advantageously permanently assembled to the tube 40, it could be envisaged, in a variant, to be able to separate from the tube 40.

Le raccord 38 et l'embase 30 ont des formes conjuguées pour permettre leur adaptation.The connector 38 and the base 30 have conjugate shapes for allow their adaptation.

Le raccord 38 de la cartouche comporte une paroi cylindrique circulaire externe 46 propre à être reçue dans une paroi cylindrique circulaire interne 48 de l'embase. Dans la paroi 46 sont ménagées deux gorges annulaires 50 et 52 propres a recevoir deux joints d'étanchéité toriques 54 et 56.The connector 38 of the cartridge has a cylindrical wall external circular 46 suitable for being received in a wall cylindrical internal circular 48 of the base. In the wall 46 are formed two annular grooves 50 and 52 suitable for receive two O-rings 54 and 56.

La paroi cylindrique 48 de l'embase 30 se poursuit par un fût cylindrique coaxial 58 qui est relié a la paroi 48 par une partie annulaire 60.The cylindrical wall 48 of the base 30 continues with a barrel coaxial cylindrical 58 which is connected to the wall 48 by a annular part 60.

Les tubulures 34 et 36 débouchent respectivement dans la paroi cylindrique 48 et dans le fût 58 de l'embase 30.Tubes 34 and 36 open respectively into the cylindrical wall 48 and in the barrel 58 of the base 30.

L'embase 30 définit un logement axial borgne 62 qui communique avec la tubulure de sortie 36 et un logement annulaire 64 qui communique avec la tubulure d'entrée 34.The base 30 defines a blind axial housing 62 which communicates with outlet pipe 36 and annular housing 64 which communicates with the inlet pipe 34.

Le raccord 38 comporte en outre un embout axial creux 66 qui est relié a la paroi cylindrique 46 par l'intermédiaire d'un fond perforé 68 de forme annulaire. Ce fond perforé est muni d'une ou plusieurs ouvertures 70 qui font communiquer l'intérieur de la cartouche avec le logement annulaire 64 lorsque cette cartouche est reçue dans l'embase.The connector 38 further includes a hollow axial tip 66 which is connected to the cylindrical wall 46 by means of a perforated bottom 68 of annular shape. This perforated bottom is provided one or more openings 70 which communicate inside the cartridge with annular housing 64 when this cartridge is received in the base.

Lorsque l'embout axial 66 est reçu dans le logement axial 62, le raccord 38 est relié de façon étanche a l'embase et le fluide frigorigène peut circuler successivement du compartiment supérieur 24 vers le logement annulaire 64 en passant par la tubulure d'entrée 34. Ensuite, le fluide frigorigène gagne l'intérieur de la cartouche 28 puis quitte cette dernière par l'embout axial creux 66 et par la tubulure de sortie 36 pour gagner le compartiment inférieur 26.When the axial end piece 66 is received in the axial housing 62, the connector 38 is tightly connected to the base and the refrigerant can flow successively from the compartment upper 24 towards the annular housing 64 passing through the inlet pipe 34. Next, the refrigerant wins inside the cartridge 28 then leaves this last by the hollow axial end piece 66 and by the tubing of exit 36 to reach the lower compartment 26.

Dans l'exemple de réalisation représenté, l'embout axial 66 est muni d'un filetage externe 72 propre à coopérer avec un filetage interne 74 du logement axial 62 de l'embase.In the embodiment shown, the axial end piece 66 is provided with an external thread 72 capable of cooperating with a internal thread 74 of the axial housing 62 of the base.

La cartouche 28 est destinée a contenir un produit desséchant (non représenté) pour déshydrater le fluide frigorigène. Dans la forme de réalisation de la figure 1, l'embase 30, y compris les tubulures 34 et 36, est réalisée d'une seule pièce, par exemple par matriçage à partir d'un matériau métallique, avantageusement un alliage d'aluminium.The cartridge 28 is intended to contain a drying product (not shown) to dehydrate the refrigerant. In the embodiment of Figure 1, the base 30, y including tubing 34 and 36, is made in one part, for example by stamping from a material metallic, preferably an aluminum alloy.

Les tubulures 34 et 36 comportent des extrémités libres 76, 78, de plus petit diamètre, propres à être engagées dans des ouvertures appropriées ménagées dans la paroi de la boíte collectrice 16.Tubing 34 and 36 have free ends 76, 78, of smaller diameter, suitable for being engaged in suitable openings in the wall of the box collector 16.

On comprendra que les ouvertures peuvent être réalisées en des endroits choisis de la boíte collectrice 16, en particulier dans une position angulaire choisie (voir l'angle α1 de la figure 2) par rapport à l'axe YY de la boíte collectrice 16. L'angle α1 peut varier de 0 a 180°.It will be understood that the openings can be made in selected locations of the manifold 16, in particular in a chosen angular position (see the angle α1 of Figure 2) relative to the YY axis of the manifold 16. The angle α1 can vary from 0 to 180 °.

Par ailleurs, les tubulures 34 et 36 peuvent être disposées dans une position non radiale par rapport à l'axe du logement axial 62 pour incliner plus ou moins la cartouche par rapport à l'axe YY, comme représenté par l'angle α2 sur la figure 2. In addition, the tubes 34 and 36 can be arranged in a non-radial position relative to the axis of the housing axial 62 to tilt the cartridge more or less relative to to the YY axis, as shown by the angle α2 in Figure 2.

A cet égard, l'angle α2 peut varier entre 0 et 90° par rapport aux génératrices de la boíte collectrice.In this respect, the angle α2 can vary between 0 and 90 ° by compared to the generators of the manifold.

Enfin, il est possible de faire varier la position de la cartouche en la faisant pivoter d'un angle α3 de ± 90° par rapport aux génératrices de la boíte collectrice, comme montré également sur la figure 2.Finally, it is possible to vary the position of the cartridge by rotating it by an angle α3 of ± 90 ° by compared to the generators of the manifold, as also shown in Figure 2.

Ainsi, on comprendra qu'il est possible de donner une multiplicité de positions ou d'orientations à la cartouche 28, soit en fonction de la position des trous de réception des tubulures, soit en fonction de la configuration de l'embase.Thus, it will be understood that it is possible to give a multiple positions or cartridge orientations 28, or depending on the position of the receiving holes tubing, either depending on the configuration of the base.

La cartouche 28 ne contient que du fluide frigorigène condensé a basse température et permet de compenser les variations de volume du fluide frigorigène dans le circuit, tout en déshydratant le fluide frigorigène.Cartridge 28 contains only refrigerant condensed at low temperature and compensates for variations in the volume of the refrigerant in the circuit, while dehydrating the refrigerant.

Si la cartouche 28 doit être échangée, il suffit de procéder à son dévissage en actionnant sa tête 44, qui peut être par exemple réalisée sous la forme d'une tête à six pans, puis de la remplacer par une cartouche neuve.If cartridge 28 needs to be replaced, just proceed when it is unscrewed by actuating its head 44, which can be by example produced in the form of a hexagon head, then replace it with a new cartridge.

On se réfère maintenant à la figure 3 qui montre une autre variante de réalisation de l'invention.We now refer to Figure 3 which shows another variant embodiment of the invention.

Dans cette variante, la cartouche 28 est strictement identique à la cartouche 28 de la figure 1.In this variant, the cartridge 28 is strictly identical to the cartridge 28 of FIG. 1.

Par contre, l'embase 30 comporte un corps cylindrique 80 dans lequel sont ménagés le logement axial 62 et le logement annulaire 64.On the other hand, the base 30 comprises a cylindrical body 80 in which are formed the axial housing 62 and the housing ring finger 64.

Par contre, le logement axial 62 au lieu d'être borgne débouche sur une face d'extrémité 82 du corps 80.By cons, the axial housing 62 instead of being blind opens onto an end face 82 of the body 80.

Par ailleurs, un autre alésage axial 84, qui s'étend parallèlement au logement axial 62, débouche dans le logement annulaire 64 et dans la face d'extrémité 82. Au voisinage de leur débouché sur la face d'extrémité 82, le logement axial 62 et l'alésage 84 comportent des parties élargies respectives 86 et 88. Ces parties élargies sont destinées à recevoir les extrémités de deux tubulures 90 et 92 servant respectivement à l'entrée et à la sortie du fluide frigorigène.Furthermore, another axial bore 84, which extends parallel axial housing 62, opens into the housing annular 64 and in the end face 82. In the vicinity of their outlet on the end face 82, the axial housing 62 and bore 84 have respective enlarged portions 86 and 88. These enlarged parts are intended to receive the ends of two pipes 90 and 92 respectively serving at the inlet and outlet of the refrigerant.

Les tubulures 90 et 92 sont donc indépendantes du raccord. Elles possèdent chacune une première extrémité qui est avantageusement reliée par brasage à l'embase 30 et une seconde extrémité qui est également avantageusement reliée par brasage à la paroi de la boíte collectrice 16.The pipes 90 and 92 are therefore independent of the connector. They each have a first end which is advantageously connected by soldering to the base 30 and a second end which is also advantageously connected by brazing to the wall of the manifold 16.

Les tubulures 90 et 92 peuvent être coudées de façon appropriée pour donner une orientation choisie à l'embase 30 et, par conséquent, à la cartouche 28.Tubing 90 and 92 can be bent appropriately to give a chosen orientation to the base 30 and, therefore, to cartridge 28.

Il est à noter que, sur la figure 3, les tubes 12 du condenseur n'ont pas été représentés aux fins de simplification du dessin.It should be noted that, in FIG. 3, the tubes 12 of the condenser have not been represented for the sake of simplification drawing.

Le fonctionnement de la cartouche 28 de la figure 3 est similaire a celui de la cartouche 28 de la figure 1.The operation of the cartridge 28 of FIG. 3 is similar to that of the cartridge 28 in FIG. 1.

Il est à noter qu'une même cartouche peut être utilisée aussi bien dans l'embase 30 de la figure 1, que dans l'embase 30 de la figure 3.Note that the same cartridge can also be used well in the base 30 of FIG. 1, that in the base 30 of Figure 3.

Bien entendu, l'invention n'est pas limitée aux formes de réalisation décrites précédemment à titre d'exemple.Of course, the invention is not limited to the forms of realization described previously by way of example.

Ainsi, il est possible d'utiliser des embases de configurations différentes, pourvu qu'elles permettent la réception du raccord de la cartouche.Thus, it is possible to use manifolds of configurations different, provided that they allow the reception of cartridge connection.

Egalement, la cartouche pourrait, en variante, être munie d'un bouchon amovible pour permettre de remplacer uniquement son produit desséchant, si nécessaire. Also, the cartridge could, as a variant, be provided a removable cap to allow replacement only its drying product, if necessary.

Enfin, bien que l'invention ait été décrite dans une application préférentielle à une installation de climatisation de véhicule automobile, il doit être entendu qu'elle peut être utilisée dans d'autres circuits de réfrigération.Finally, although the invention has been described in an application preferable to an air conditioning installation of motor vehicle it should be understood that it can be used in other refrigeration circuits.
