    Reservoir of phase change material provided with a filling tube of said tank for a heat exchanger of an air conditioning installation of a motor vehicle
    The present invention is in the field of heat exchangers equipping motor vehicles, including an evaporator. The heat exchanger of the present invention relates more specifically to those comprising at least one storage tank of a phase change material (PCM). Such a reservoir typically constitutes an intermediate heat transfer member, being interposed between two fluid transfer conduits refiigeant through the heat exchanger.
    Motor vehicles are commonly equipped with a ventilation system, heating and / or air conditioning, also known as air conditioning installation. Such an installation is particularly dedicated to the treatment of the air contained in the cabin of the vehicle, for its renewal and / or for its heating or conversely for its cooling according to the comfort desired by the passengers. For this purpose, the installation typically comprises a closed air conditioning circuit in which circulates a refrigerant supplying one or more heat exchangers, such as in particular at least one evaporator. Successively following the flow direction of the fluid through it, the air conditioning circuit essentially comprises a compressor, a condenser or gas cooler, im expander and the evaporator. The fluid is thus compressed in the gas phase by the compressor, converted into a liquid phase in the condenser or simply cooled by the gas refi-oxidizer, expanded at low pressure by the expander and then converted into a gas phase in the evaporator and again conveyed to the compressor.
    A heat exchanger equipping an air conditioning installation of a motor vehicle commonly comprises a bundle of conduits. The ducts are each arranged in a tube formed between two adjacent duct plates. The ducts are arranged parallel to each other at a distance from one another so as to provide a circulation space for heat-treated air between them. The ducts are commonly mounted in parallel between an intake pipe and a refrigerant discharge pipe, respectively inside and outside the heat exchanger.
    Thus, with respect to such an evaporator-function heat exchanger, the refrigerant admitted into the heat exchanger flows through the conduits and is discharged from the heat exchanger to the compressor. The air to be cooled yields calories as a result of its circulation through the spaces between the ducts. Interlayers are interposed between the conduits to increase the heat exchange surface with the air flow.
    In this context, the present invention is part of the difficulties of cooling the air flowing through the evaporator. Indeed, the compressor is commonly driven by the propulsion engine of the vehicle. When the engine is stopped, the circulation of the refrigerant is interrupted and the heat exchange between the evaporator and the air to be cooled deteriorates significantly. However, motor vehicles are increasingly equipped with automatic engine shutdown systems when the vehicle progress is momentarily interrupted.
    To overcome this drawback, it is known to equip the heat exchangers, more specifically evaporator, at least one storage tank of a phase change material. Such a phase change material is commonly referred to as PCM, according to the acronym Phase Change Material. Thus, when the air conditioning circuit operates, the phase change material gives calories to the cooling fluid, solidifying. Stopping the compressor drive by the propulsion engine of the vehicle causes the shutdown of the air conditioning circuit. The flow of air passing through the heat exchanger is then cooled on contact with the reservoir (s) containing the phase-change material, which takes heat from the air stream by liquefying.
    An evaporator illustrating this context is disclosed in WO2013125533A1 (SANDEN Corp.). The tank disclosed in this document is formed between two tank plates arranged in half-shells and respectively in contact against two ducts in which a fluid circulates. To fill the tank, the tank plates each have a spout forming a filling channel of the phase change material.
    Document FR3014183A1 (VALEO THERMAL SYSTEMS) discloses another evaporator adapted to the context presented above. The fluid conduits are delimited by two duct plates and an intermediate plate is interposed between two ducts. The PCM reservoir is then constituted by the space formed between the intermediate plate and a conduit plate.
    The designs presented above suffer from a disadvantage relating to the filling of the storage tank of the phase change material. Indeed, the filling nozzles of WO2013125533A1 are not transposable in the evaporator shown in document FR3014183A1, because the reservoir of phase change material of the first document is delimited by two plates dedicated to the reservoir, while the second document does not include only one plate.
    In this context, the present invention relates to a tank of a phase change material for im heat exchanger equipping an air conditioning installation of a motor vehicle. The present invention also relates to such a heat exchanger comprising one or more tanks according to the present invention. The present invention also relates to a method of filling a tank according to the present invention with a phase change material.
    The main object of the present invention is to improve the filling conditions of the tank, while optimizing its capacity for a given space between the respective duct plates of two adjacent ducts. Such an improvement is in particular sought by avoiding modifying the structure of the duct plates, a common desired for all the duct plates equipping the chalexu exchanger · in the presence or absence of a reservoir interposed between them.
    The desired improvements are also desired by reinforcing the tightness of the tank in the context of temperature variations to which the reservoir is subjected in operation and may affect the stability of its structure.
    Account must also be taken of the economic constraints to which motor vehicle equipment manufacturers are well known. The production costs of the heat exchanger must not be economically unacceptable with regard to the benefits provided. This is the case more specifically with regard to the tank and the heat exchanger forming the subject of the present invention, in particular with regard to the structure of the tank and the methods of its installation on the heat exchanger, as well as to the look at the methods used to fill it.
    The PCM tank of the present invention is organized to form a component of a heat exchanger of an air conditioning installation of a vehicle, particularly a car. The tank is provided with a filling means.
    In this context, the reservoir of the present invention is mainly recognizable in that the reservoir of phase change material is formed between two tank plates, where the filling means comprises at least one tube delimiting a filling channel arranged at the bottom of the tank. outside the tank against the first tank plates.
    The filling channel is disposed laterally relative to the reservoir, that is to say beside it and in contact with an outer face of the first plate defining the reservoir. The concept of "lateral" defines an arrangement of the filling channel against the first tank plate parallel to the general plane of this plate. The filling channel is thus mainly oriented along the width of the first plate defining the reservoir, and can provide an emergence of the filling means out of the heat exchanger, that is to say beyond a plane. defining an inlet or outlet face of the air stream of the constituent duct bundle of the heat exchanger. The position outside the reservoir filling channel involves its location out of the volume of the reservoir delimited between the two tank plates, the supply channel connecting an interior volume of the filling channel with an internal volume of the reservoir.
    The reservoir advantageously comprises any one of the following characteristics, taken alone or in combination: a supply channel connecting the filling channel to an interior volume of the reservoir delimited by the two tank plates, the filling channel; extends in a main plane oriented parallel to a general plane of the tank plates, the feed channel extending along an axis oriented transversely to the general plane of the tank plates, the feed channel is formed by openings communicating between they and formed respectively through the tube and through the first tank plate. The openings can be easily made by machining, or more advantageously by stamping during the formation of the first tank plate, a positioning means of the tube on the first tank plate is provided, the positioning means is formed by less im collar bordering at least a first opening and nested inside a second opening. Such collar may be formed by repressing material from the second opening during the manufacture of the first tank plate by stamping, the collar is formed protruding from the first tank plate to the outside of the tank. Similarly but reversed, the collar is formed projecting from an outer face of the filling channel to enter the opening in the first plate defining the reservoir. When placing the filling channel in application against the first tank plate, the collar is introduced inside the opening that includes the tube to spare the feed channel, the positioimation means is configured to that a longitudinal axis of the filling channel is transverse, in particular perpendicular, to im longitudinal axis of the tank plates. It can be provided a series of passages defined by the openings, for example of circular section. Alternatively, a single pass may be provided. Complementarily but optionally, such passage may have an oblong section. In the two cases mentioned here, it ensures an angular pre-positioning of the filling means with respect to the reservoir and it is ensured that the filling means is accessible from outside the heat exchanger, after brazing thereof, the tube is attached against a seat provided on the outside face of the first tank plate; the seat delimits a chamber for feeding the reservoir from the feed channel to a reserve extending in extension of the chamber; feeding, according to longitudinal plane of extension of the first tank plate, cumulative dimensions of the feed chamber and the filling channel are at most equal to one dimension of the reserve, measured in a direction perpendicular to the plane of the first tank plate, the filling means comprises at least one connecting piece which extends beyond a trans dimension tank plate and configured to port the fill channel with an external supply flow of the tank of phase change material. It will be noted that the emergence of a proximal portion of the connecting piece out of the volume defined between the tank plates allows its free arrangement to connect to the supply circuit, regardless of the arrangement of the filling channel, a distal end of the filling channel is closed by deformation of its edges, in particular by bringing them closer together and brazing, since the proximal end of the connection piece is closed indifferently by adding a plug or by deforming its edges, particularly by bringing them closer together and brazing, the distal end of the filling channel is flattened so as to form a closing edge parallel to the general plane of the first tank plate. the first tank plate is arranged in an open shell on the second tank plate, the shell defining the volume of the tank and being sealed, in particular brazed, by its peripheral edge surrounding the volume of the tank to the second tank plate; reservoir is arranged in a plurality of recesses, for example formed by cells formed by reliefs that comprises the first tank plate, - the filling channel is reported by sealing, in particular by brazing, for example simultaneously with the beam of ducts, against the first tank plate.
    Thus, the filling channel constituting the tank filling means is a separate member of the tank plates leaving between them the tank. The filling conditions of the PCM tank can be freely and specifically organized as a result of such a structural distinction between the tube and the tank plates leaving the tank. In addition, the filling channel being attached against the first tank plate, a specific arrangement of only xme tank plates is necessary to arrange the filling means of the tank. As a result, the arrangement of the second tank plate, delimiting the internal volume of the tank with the first tank plate, is made freely available.
    Thus, the second tank plate may advantageously consist of a duct plate constituting the heat exchanger identical to all the duct plates of the heat exchanger. Poxor reminder, such a household conduit plate with another duct plate adjacent a conduit of the heat exchanger carrying a fluid, including refiigrant, providing im heat exchange between the fluid, the PCM and air.
    This finally results in a freedom of organization of the reservoir filling procedures and optimization of the heat exchange between the reservoir and the heat exchanger conduits between which the reservoir is interposed.
    According to a simple embodiment, the feed channel is formed by openings formed respectively through the tube and through the first tank plate. Said openings are communicating with each other by abutment to one another according to the orientation of their outlet transversely, and more particularly perpendicular to the general plane of the tank plates.
    The present invention also relates to wine heat exchanger, in particular used as an evaporator of an air conditioning installation of a vehicle, especially automobile. The heat exchanger of the present invention is mainly resettable in that it is provided with at least one storage tank of a phase change material as just described in accordance with the present invention. Of course, the heat exchanger preferably comprises a plurality of PCM tanks according to the present invention, each interposed between two conduits of the heat exchanger conveying a fluid, for example refrigerant, dedicated to the cooling of a flow of water. air passing through the heat exchanger.
    More particularly as a result of the installation of the PCM tank in the heat exchanger, the second tank plate advantageously consists of a first duct plate of the heat exchanger identical to the set of duct plates that includes the heat exchanger. As a reminder, such a first duct plate classically household with a second adjacent duct plate a first conduit participating a bundle of ducts dedicated to the circulation of a fluid through the heat exchanger.
    The first tank plate is preferably affixed, of course in its general plane, against a third pipe plate. The third duct plate houses with a fourth duct plate adjacent a second duct conduit duct. Thus, the reservoir is placed directly in contact with two duct plates leaving respective adjacent ducts of the heat exchanger. The performance of the heat exchange between the duct plates and the tank is thus optimized. The tank capacity is optimized according to its dimension oriented perpendicularly to the duct plates. The action and reaction time of the phase change material is also improved by such a design. The reservoir can be easily interposed between two duct plates to replace a spacer equipping the heat exchangers to promote heat exchange between the air to be cooled and the heat exchanger. The invention also covers the case where at least one first fluid circulation duct is delimited by at least a first duct plate and a second duct plate, as well as a second duct delimited by a third duct plate and by a fourth duct plate, and wherein the second tank plate is distinct from any of the duct plates.
    The present invention also relates to a method of filling a storage tank of phase change material according to the present invention comprises im heat exchanger as just described.
    It will be noted that the method of the present invention is proposed by distinction of the methods usually used to fill a PGM tank installed on a heat exchanger, in particular used as an evaporator, equipping the air conditioning installations for air conditioners. motor vehicles. It is thus understood that the organization of the tank of the present invention allows its filling by any other method than that advantageously proposed by the present invention. However, it is found that the processes usually used to fill the tank fill can make random optimization of its filling.
    Indeed, the reservoir of the present invention is preferably arranged in a plurality of recesses formed by cavities formed by reliefs that includes the first tank plate. The reliefs are advantageously integrated into the shell during its formation by stamping. Such a honeycomb arrangement of the tank provides a homogeneous distribution of the PGM inside the tank. In this context, the optimized filling of each of the cells of the tank by the PGM is difficult to obtain. The organization of the reservoir of the present invention advantageously makes it possible to operate, according to a method of the present invention, a filling of the reservoir by suction of the PGM from the reservoir, as a result of its prior depression.
    More particularly, and for example, the process of the present invention comprises the following operations: -) connecting the filling channel to a vacuum generating apparatus, particularly a vacuum pump. The filling channel is connected to the vacuum generating apparatus via an open end of the filling channel, in particular formed by its proximal end arranged as a connection end to the supply circuit of the PGM tank. -) vacuum the tank by suction of the air it contains through the supply channel and the filling channel. Said suction is obviously provided by the implementation of the general apparatus of depression previously connected to the filling channel via the connecting piece. -) break the fluidic interchange between the filling channel and the vacuum generating apparatus. Such a communication break can for example be effected by means of a valve selectively providing the communication between the tank on the one hand with the vacuum generating apparatus for its evacuation, and on the other hand with a source of phase change material for its filling. -) place the tube in communication with said source of phase change material. As previously mentioned, the communication between the filling channel and the source of PGM can be operated via the valve interposed between the vacuum generating apparatus and the source of PGM. Such comminution causes aspiration by filling the reservoir from the source of PGM under the effect of its depression beforehand. -) break the communication between the filling channel and the PGM source, and then close the open end of the filling channel, in particular formed by its proximal end.
    It is understood that the PGM tank supply circuit comprises a depressurization circuit comprising the vacuum generator apparatus. With respect to the reservoir, the depressurization circuit is in particular placed in parallel with a PGM delivery circuit comprising the source of PGM. The depressurization circuit and the PGM delivery circuit are alternately communicated with the reservoir via said valve. Other characteristics, details and advantages of the present invention will emerge more clearly on reading the description given below as an indication, in relation to the exemplary embodiments of the invention illustrated in the figures of the attached plates, in which Fig. 1 is a perspective view of a heat exchanger according to the present invention; Fig. 2 and Fig. 3 are perspective illustrations of components of the heat exchanger shown in Fig. 1, respectively; in an exploded view and in an assembled view, FIG. 4 is composed of three diagrams (a), (b) and (c) successively illustrating methods of assembly between components of a PGM tank according to the present invention, In the heat exchanger shown in FIG. 1, FIG. 5 is composed of four diagrams (d), (e), (f) and (g) successively illustrating the method of filling the PCM tank shown in Figure 3.
    It should first be noted that the figures show the present invention in detail and in particular ways of its implementation. Said figures and their description can of course be used, if necessary, to better define the present invention, both in its particularities and in its generality, particularly in relation to the description of the present invention that is made herein.
    Moreover, to clarify and make it easy to read the description that will be made of the present invention in relation to the figures of the attached plates, the common members shown in the various figures are respectively identified in the descriptions of these figures with the same numbers and / or letters of reference, without involving their individual representation in each of the figures and / or an identical arrangement of said common members between specific embodiments.
    In Figure 1, a heat exchanger 1 according to the present invention team ime installation of air conditioning of a motor vehicle. The illustrated heat exchanger 1 is more specifically used as evaporate dedicated to the cooling of an air flow sent into the passenger compartment of the vehicle. The description below is made in connection with a heat exchanger, but it is clear that all the arrangements described herein preferably apply to an evaporator. The heat exchanger 1 comprises a bundle of conduits 2, the ducts 3 of the bundle of ducts 2 being intended to convey a fluid F configured to capture calories to cool the air flow. Such a fluid may be a heat transfer fluid, but it may also be a refnigerent fluid, for example diphasic. The ducts 3 of the duct bundle 2 are each arranged in a tube being individually formed between two duct plates, such as for example illustrated in FIG. 2 and FIG. 3. Tabs 4, arranged in fins for example, are placed between most ducts 3 to increase the heat exchange surface between the air to be cooled and the heat exchanger 1.
    More particularly, FIG. 2 and FIG. 3 illustrate two adjacent conduits 3a, 3b of the duct bundle 2 equipping the heat exchanger shown in FIG. 1. The ducts 3a, 3b are each formed between two duct plates 5a, 5b and 6a, 6b which extend mainly along their general plane PI, parallel to each other and perpendicular to the general plane P2 of the heat exchanger 1. As illustrated in FIG. 3, the ducts 3a and 3b are arranged parallel distance remotely vms of others to provide between them a circulation space air to be heat treated.
    In FIG. 1 in particular, the ducts 3 are connected in parallel, as a result of the fluid F, between an intake duct 7a and a discharge duct 7b of the fluid F. The intake duct 7a and the evacuation duct 7b comprising respective fluid passages 8a, 8b formed through the conduit plates and successively abutting each other when the conduits 3 are joined together.
    The fluid F is admitted inside the heat exchanger 1 through the intake pipe 7a, circulates through the ducts 3 and is then evacuated out of the heat exchanger 1 through the evacuation pipe 7b . The ducts 3 are arranged in two parallel fluid flow passages connected to each other at the base of the heat exchanger opposite its top comprising the intake pipe 7a and the evacuation pipe 7b. For this purpose, the duct plates 5a, 5b and / or 6a, 6b are partitioned along their largest dimension to accommodate both fluid passes. This larger dimension defines a longitudinal axis in which the ducts extend.
    Furthermore, the heat exchanger 1 comprises a plurality of reservoirs 9 containing a phase change material, referred to herein as PCM. Such tanks 9 make it possible to cool the air circulating through the heat exchanger 1 in the absence of circulation of the fluid F in the ducts 3. Each reservoir 9 is interposed in contact between two participating duct plates of the respective formation. two adjacent ducts 3. Thus, the tanks 9 are arranged between two adjacent ducts 3 to replace tabs 4, for this purpose absent from the heat exchanger 1. The tanks 9 are each equipped with a means 14 for filling them in PCM when is installed on the heat exchanger 1.
    More particularly in Figures 2 to 4, a reservoir 9 equipping the heat exchanger 1 shown in Figure 1 is formed between two adjacent tank plates 10a, 10b, oriented parallel to one another. A first tank plate 10a is arranged in shell 11, one of the faces 12 is open to a second tank plate 10b. The first tank plate 10a is brazed through its peripheral edge 13 against the second tank plate 10b.
    The second tank plate 10b may consist of a tank plate exclusively dedicated to the tank 9 and intended to be affixed against a pipe plate of the adjacent heat exchanger 1, such as in particular the conduit plate 6a. duct 3b. It will be noted, however, that according to an advantage provided by the present invention, the second tank plate 10b advantageously consists of a first duct plate 6a forming a duct 3 of the heat exchanger 1, such as the duct 3b according to the form preferred embodiment of the invention.
    More particularly, the first duct plate 6a, with a second adjacent duct plate 6b, provides a first duct 3b of the heat exchanger 1. The first tank plate 10a made up of the shell 11 is advantageously directly affixed against a third duct a duct plate 5a forming, with a fourth duct plate 5b adjacent, a second duct 3a of the heat exchanger 1. It is therefore understood that according to this variant, the tank 9 is delimited on one side by the first tank plate 10a and the first duct plate 6a, the latter forming an embodiment of the second tank plate 10b.
    For the filling of the reservoir 9, a tube 15 is laterally attached and soldered against a flat seat 16 formed on the outer face of the shell 11. The seat 16 projects outwardly from the first plate of tank 10a perpendicularly to its general plane PI. The seat 16 delimits a feed chamber 17 (FIG. 4) of the tank 9 made of PGM, arranged along the general plane PI of the first tank plate 10a extending from a reserve 18 to PGM forming the major part of the tank 9. .
    It will be noted that the tube 15 described below forms an envelope of the filling channel 19, the latter constituting the means 14 for filling the storage tank 9 with PCM. The filling channel 19 is then a volume surrounded by the tube 15, this volume being filled by the phase change material.
    The tube 15 extends parallel to the general plane of the first tank plate 10a, being oriented along its longitudinal axis perpendicularly to the general plane P2 of the heat exchanger 1, as illustrated in FIG.
    More particularly, in the diagrams of FIG. 4, the tube 15 forms, between its ends in its general direction DI of extension illustrating its longitudinal axis, the filling channel 19 through which the PCM can be admitted to the reservoir 9 for its filling. It will be noted, when the tube 15 is installed on the first tank plate 10a, and that the tube 15 is oriented along its direction DI and parallel to the smallest dimension of the first tank plate 10a, considered in its general plane PL In in other words, the longitudinal axis of the tube 15 is parallel to the transverse direction of the reservoir 9.
    A distal portion 15a of the tube is housed between the tank plates 10a, 10b and forms a connecting member by brazing the tube 15 against the seat 16 formed on the first tank plate 10a. The distal portion 15a of the tube 15 is extended by a proximal portion 15b arranged as a connection end of the reservoir 9 to a supply circuit 20 (Figure 5) of the tank 9 PCM. The connecting end 15b of the filling means 14 is emerging out of the duct bundle 2 of the heat exchanger 1, perpendicularly to its general plane P2 as illustrated in FIG. 1. The notions of distal and proximal are commonly understood to be opposite relative notions with respect to a given direction of extension of an organ. Of course with regard to the tube, said given direction is identified as targeted between the ends of the tube. The distal end 21a of the tube 15 forming the filling channel 9 is closed by deformation and sealing of its edges with each other, in particular by bringing its edges closer together and brazing. A proximal end 21b of the connecting piece 15b provides a PCM intake mouth 21c inside the tube 15 when filling the reservoir 9. The mouth 21c is kept open while filling the reservoir 9, and is closed after filling of the reservoir 9 as illustrated in the diagram (g) of FIG. 5. The closure of the mouth 21c can be achieved by means of an attached plug or, as illustrated, by deformation and sealing between them the edges of the proximal end 21b of the connecting piece 15b. Here too, the closure of this proximal end 21b of the connecting piece 15 is operated by bringing the edges together and soldering them.
    The filling channel 19 communicates with the feed chamber 17 via a feed channel 22. The feed channel 22 extends perpendicular to the general plane PI of the first tank plate 10a, being formed by openings 22a, 22b communicating with each other and respectively through the tube 15 and through the seat 16. The openings 22a, 22b are each composed of two holes 23a, 23b and 24a, 24b adjacent. The plurality of holes 23a, 23b and 24a, 24b respectively forming the openings 22a, 22b makes it possible to take advantage of the openings 22a, 22b to pre-position the tube 15 on the first tank plate 10a, in particular to prevent rotation of the means 14 filling during the brazing operation of the heat exchanger. For this purpose in the diagram (a) of Figure 4, the holes 23a, 23b are each bordered by a collar 25a, 25b. The flanges 25a, 25b are respectively nestable inside the holes 24a, 24b formed through the tube 15. Thus, the tube 15 is rigorously positioned against the seat 16 and held in position as a result of its brazing on the first plate tank 10a. The distal end 21a of the tube 15 is flattened by generating a force perpendicular to the general plane PI of the first tank plate 10a. Perpendicularly to the general plane PI of the first tank plate 10a, the dimensions ciunulés a, b respectively of the feed chamber 17 and the tube 15, are at most equal to the dimension c of a reserve PCM 18 that includes the reservoir 9. Thus, the tube 15 interposed between the first tank plate 10a and the conduit 3a, does not prevent a direct apposition of the first tank plate 10a against the third conduit plate 5a to optimize the exchange thermal between them.
    In the diagrams (a), (b) and (c) of FIG. 4, the reservoir 15 is composed in all and for all of three reservoir elements 10a, 10b, 15 assembled by soldering together as illustrated in FIG. diagram (c). A first reservoir member is formed by the first reservoir plate 10a, a second reservoir member is formed by the second reservoir plate 10b, which may be a conduit plate, and a third reservoir member is formed by the tube 15 delimiting the filling channel 19.
    Successively in the diagram (a) and then in the diagram (b), the tube 15 is positioned on the first tank plate 10a by placing its distal portion 15a against the seat 16. The flanges 25a, 25b bordering the holes 23a, 23b formed through the seat 16 are respectively introduced inside the holes 24a, 24b formed through the tube 15.
    Thus, as illustrated in diagram (b), stacking of duct plates and tank plates 10a, for example equipped with tube 15, can be carried out.
    Successively in the diagram (b) and then in the diagram (c), the assembly consisting of the tube 15 pre-positioned against the first tank plate 10a is attached and then brazed to the second tank plate 10b via the peripheral edge 13 of the first tank plate 10a. It will be noted that the second tank plate 10b comprises a member 26a which partitions the conduit 3b in two passes. The integration of the reservoir 9 with the heat exchanger 1 is then performed from the mounting of the first duct plate 6a advantageously constituting the second tank plate 10b.
    The reservoir 9 is placed in interposition between two ducts 3a, 3b of the heat exchanger 1 as illustrated in FIG. 1. The first tank plate 10a is affixed in direct contact with the third duct plate 5a. It will be noted that the shell 11 has reliefs 27 through which the first tank plate 10a bears against the third pipe plate 5a. Such reliefs 27 provide inside the tank 9 receiving cells PGM distributed in the reserve 18.
    In FIG. 5, the filling of the reservoir 9 is carried out after it is secured to the heat exchanger 1. The filling of the reservoir 9 in PCM is carried out by suction from a prior depression of the reservoir 9. For this purpose , as shown in the diagram (d), the reservoir 9 is connected to a PCM supply circuit 20 via the connecting end 15b of the tube 15 and whose outlet is open to the outside .
    The supply circuit 20 comprises a depressurization circuit 20a and a PCM delivery circuit 20b, connected in parallel with the supply circuit 20 via a valve 30. The depressurizing circuit 20a comprises a generating device 28 and the PCM delivery circuit comprises a PCM source 29. The vacuum generating apparatus 28 and the PCM source 29 are connected in parallel with the supply circuit 20 individually connected to the valve 30. The valve 30 is connectable to the tube 15 via its connection end 15b to wine hydraulic circuit, supply circuit 20 in particular. The vaime 30 makes it possible to put the reservoir 9 selectively in communication with the vacuum generating apparatus 28 or with the PCM source 29.
    Thus, in the diagram (e), the reservoir 9 is placed in communication with the vacuum generating apparatus 28 via the valve 30. The air contained in the reservoir 9 is then sucked out of the reservoir 9 and is evacuated through the depressurization circuit 20a. As a result, the reservoir 9 is depressurized, in other words evacuated.
    In Fig. (F), the reservoir 9 is then placed in communication with the PCM source 29 through the valve 30 and the PCM delivery circuit 20b. As a result of the prior depression of the reservoir 9, the PCM is sucked through the supply circuit 20 from the PCM source 29 to the reservoir 9 for filling. Thus, all the cells of the tank 9 are effectively all filled with PCM and the efficiency of the heat exchange between the tank 9 and the air flow refi-oidir is improved.
    In the diagram (g), the connection of the tube 15 with the supply circuit 20 PCM is broken and the proximal end 21b of the connecting end 15b leaving the mouth 21c is closed. This obturation is for example carried out, as illustrated, by deformation of its edges, including approximation thereof, and soldering them.
    The phase-change material used to fill the tank 9 is paraffin-based or may still be based on a saturated fatty acid ester derived from animal or vegetable fats.
