    [0001] 1 Tube with phase change material tank for heat exchanger. The present invention relates to a tube with a phase change material reservoir for a heat exchanger heat exchange beam, particularly in the field of thermal management in a motor vehicle. The heat exchangers generally comprise a bundle of parallel tubes formed of plates containing a first coolant, for example a refrigerant in the case of an air conditioning system evaporator. The beam 10 is also traversed by a second heat transfer fluid, for example an air flow intended for the passenger compartment, sweeping the tubes, the surface of which, increased by the addition of disrupters or spacers between the tubes, optimizes the heat exchange. . It is known to provide these heat exchangers with tanks for phase change material associated with the tubes of the bundle for the circulation of the first heat transfer fluid. Such exchangers, for example in the case of an evaporator of an air conditioning circuit, make it possible to maintain the cooling of a passenger compartment of the vehicle during a given period of time, especially when the vehicle engine is stationary and does not the refrigerant circulating compressor is further driven, especially for vehicles equipped with an automatic engine shutdown system during short vehicle stops. In these periods of stopping the engine, the phase change material captures heat energy to the air passing through the evaporator so as to cool it. It is thus known in particular an evaporator for a vehicle air conditioning circuit, comprising a heat exchange bundle provided with a set of cooling fluid circulating tubes, a storage tank of phase change material being attached to the tubes and an air passage being provided between the tubes and the cold storage tanks, in particular by protrusions and recessions formed between them. In such exchangers the heat transfer between the tubes in which the coolant circulates and the tanks of phase change material is reduced firstly by the existence of said protrusions and recessions extending over a large area. each of the tubes and secondly, by the thickness of material involved in the heat transfer from the tube to the tank. Indeed, it includes the wall of the tube and the tank wall. One of the aims of the present invention is to at least partially overcome the drawbacks of the prior art and to propose an improved tube of material with phase change for a more efficient use within a beam exchange. heat of a heat exchanger. The present invention thus relates to a phase change material reservoir tube for a heat exchange beam of a heat exchanger, said phase change material reservoir tube comprising: two circulation plates configured to be assembled to one another in a sealed manner and to form at least one duct in which a first heat transfer fluid circulates, at least one tank plate, said tank plate being configured to come together sealingly on an outer face of one of the two circulation plates so as to form housings of the phase change material, said phase change material reservoir tube further comprising a filling channel of the phase change material, an end of said filling channel opening on one of the edges of said phase change material reservoir tube, said filling channel being formed on the one hand by r a filling spout of the reservoir plate to the outside and secondly by the outer face of one of the two circulation plates, said filling channel further comprising a stopper, said filling channel and said stopper being contained in a volume of width less than or equal to the width of the material tank tube 3035201 3 of phase and height less than or equal to the height of the housing of the phase change material. As a result, the filling channel does not exceed the width or height of the phase change material reservoir tube. Thus, when said phase change material reservoir tube is integrated within a heat exchange bundle, the filling channel does not protrude or interfere. According to one aspect of the invention, the filling channel comprises a stop.
    [0002] According to another aspect of the invention, the cap is made of metal. According to another aspect of the invention, the circulation plates and the reservoir plate are made of metal and fixed to each other by brazing, said metal cap being also fixed during brazing of said plates together.
    [0003] According to another aspect of the invention, the cap is made of elastomeric or plastic material. According to another aspect of the invention, the stopper is larger in size than the filling channel so as to be compressed within said filling channel. According to another aspect of the invention, the filling channel comprises a retaining tab folded over the end of said filling channel opening on one of the edges of the tube with a material reservoir with phase change.
    [0004] According to another aspect of the invention, the retaining tab is made of material with the reservoir plate. According to another aspect of the invention, the stopper comprises a filling orifice.
    [0005] According to another aspect of the invention, when it is folded down, the retaining tab covers the filling orifice of the stopper.
    [0006] According to another aspect of the invention, the retaining tab comprises a projection intended to be inserted at least partially into the plug filling orifice when said retaining tab is folded down. In another aspect of the invention, the phase change material reservoir tube has a sealant and sealant paste between the reservoir tank filler neck and the plug. Other features and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and non-limiting example, and the appended drawings in which: FIG. 1 shows a diagrammatic representation in perspective of an exploded phase change material reservoir tube; - FIG. 2 shows a schematic perspective representation of the phase change material reservoir tube of FIG. 1 assembled; FIG. 3 shows a schematic representation in perspective. of a phase change material reservoir tube according to a particular embodiment; FIG. 4 shows a diagrammatic sectional representation of a phase change material reservoir tube portion; FIG. schematic sectional representation of a tube portion with a reservoir of phase change material according to another embodiment, FIG. 6 shows a schematic perspective view of a phase change material reservoir tube according to the embodiment of FIG. 5; FIG. 7 shows a schematic perspective view of a tube assembly. 8 shows a schematic representation of a heat exchange bundle; FIG. 9 shows a diagrammatic representation in perspective of a filling channel of a tank tube. 10 shows a diagrammatic perspective and exploded representation of a filling channel of a phase change material reservoir tube; FIGS. 11a, 11b show diagrammatic representations of perspective and bottom view of a filling channel of a tube with a phase change material reservoir during different stages of assembly. In the various figures, the identical elements bear the same reference numbers. The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to one embodiment. Simple features of different embodiments may also be combined to provide other embodiments. As shown in FIG. 1, the phase change material tank tube 1 comprises two circulation plates 3 and at least one tank plate 5. The two circulation plates 3 are configured to be assembled one to the other. another sealingly and to form at least one conduit 31 in which circulates a first coolant between said circulation plates 3. The two circulation plates 3 are preferably identical and contiguous to one another in "mirror", this 3035201 6 which allows to have only one type of circulation plate 3 to produce and therefore can save money during production. The at least one tank plate 5 comprises cavities 51 and is 5 configured to come together sealingly on an external face of one of the two circulation plates 3 so as to close the cavities 51 and form cavities 51. housings of the phase change material. These cavities 51 are projecting on the external face of the reservoir plate 5 so that a second heat-transfer fluid, for example an air flow, can circulate between said cavities 51.
    [0007] In order to produce the phase change material reservoir tube 1, there are only two different types of plates used, namely two circulation plates 3 and at least one reservoir plate 5. Such a design makes it possible to limit the production of such a reservoir tube to these two types of plates, thus generating savings in production costs. In addition, because of this reduced number of plate types, the mounting is simplified. An additional advantage of the phase change material reservoir tube 1 is that the phase change material is directly in contact with the circulation plate 3, which facilitates and improves the heat energy exchange between the first heat transfer fluid and the phase change material.
    [0008] As shown in FIGS. 1, 4 and 5, the circulation plates 3 may also comprise recesses 32 preferably made by stamping in a homogeneous distribution over the entire circulation plate 3. The circulation plates 3 comprise a external face intended to be oriented towards either a tank plate 5 or a heat exchange element with the second heat transfer fluid, such as a corrugated plate. Each circulation plate 3 comprises an internal face opposite to the external face from which each recess 32 extends so that their summit part is in contact with the adjacent circulation plate 3. According to a preferred embodiment, but not limiting , the recesses 32 are staggered on the circulation plate 3. Due to such a distribution, the inner face of each recess 3035201 7 32 is in the flow path of the first fluid defined by the duct 31, while the outer face can form a local reserve of phase change material, thereby increasing their heat exchange. Because the outer face of the circulation plate 3 is provided with recesses 32, the latter form complementary reserves of phase-change material so that for a given space, a tube with a reservoir 5 of phase-change material provided with such recesses 32 allows increased storage of phase change material. This has the effect of increasing the time during which the phase change material exchanges heat energy with the second fluid. In addition, since the recesses 32 form additional connections with the adjacent circulation plate 3, the mechanical strength of the phase change material reservoir tube 1 is increased. Accordingly, such a phase change material reservoir tube 1 may be used in an evaporator type heat exchanger which is adapted to receive a refrigerant fluid having a pressure rating of approximately 15%. bar. As shown in FIG. 2, the phase change material tank tube 1 comprises a single tank plate 5 on one of its outer faces in contact with the second heat transfer fluid. The other of its faces is in contact with a corrugated heat exchange plate with the second heat transfer fluid, such corrugated plate being sometimes called fin or spacer. According to an alternative embodiment, the tube 1 may nevertheless comprise a tank plate with a reservoir of phase change material 1 on each of its external faces in contact with the second heat transfer fluid as shown in FIG. 3. In order to facilitate the filling of the projecting cavities 51 in this embodiment, the phase change material reservoir tube 1 may comprise a common filling orifice (not shown) of the projecting cavities 51 of the two reservoir plates 5.
    [0009] According to a first embodiment illustrated in FIG. 4, the projecting cavities 51 have a dome-shaped shape. These domes are more particularly staggered so that the second heat transfer fluid can flow between them.
    [0010] According to a second embodiment illustrated in FIG. 5, the projecting cavities 51 have an oblong shape. The projecting cavities 51 are then distributed in "V" with respect to the longitudinal axis A of the tank plate 5 as shown in FIG. 6. This particular shape and distribution allows the phase change material reservoir tube 1 to contain a greater quantity of phase change material than for the dome shape and also to limit the pressure drop of the second heat transfer fluid as it passes between the projecting cavities 51.
    [0011] The protruding cavities 51, whether in the first or second embodiment, have a flat apex 55 respectively of cylindrical section and of polygonal section, for example approximately trapezoidal. Such vertices 55 are intended to come into contact with an exchange tube 30 disposed vis-à-vis within the heat exchange bundle 100, as shown in FIG. 7. The exchange tube 30 may be a tube provided with micro channels, such a tube being derived from the superposition of flat plates and a corrugated plate, the latter being sometimes called internal spacer, said corrugated plate then being disposed between the two flat plates adjacent to form the micro-channels. According to an alternative embodiment, the exchange tube 30 may more particularly be composed of two circulation plates 3, as previously described, assembled to one another in a sealed manner.
    [0012] FIG. 8 shows a heat exchange bundle 100 having phase change material tank tubes 1 to eventually form a heat exchanger. The heat exchange bundle 100 here comprises, distributed over its entire length, three phase change material tank tubes 1. Two of these 5 phase change material tank tubes 1 comprise a tank plate 5 on each their external faces in contact with the second heat transfer fluid. The third tube containing material of phase change material 1 has only a single tank plate 5 on one of its outer faces in contact with the second heat transfer fluid. The total number of phase change material reservoir tubes 1 and reservoir plates 5 present within a heat exchange bundle 100 is a function of its size and length. The longer the heat exchange bundle 100, the greater this number is in order to ensure a cooling of the second heat transfer fluid continues and even if the first heat transfer fluid circulates more in said beam, for example during a shutdown of the compressor.
    [0013] Thus, it can clearly be seen that the phase change material reservoir tube 1 because it is composed of two circulation plates 3 and at least one tank plate 5, allows simple assembly and inexpensive manufacture. . In addition, the phase change material is directly in contact with the circulation plate 3, which facilitates and improves heat energy exchange between the first heat transfer fluid and the phase change material. In order to introduce the phase change material into the phase change material reservoir tube 1, the latter further comprises a filling channel 200, as illustrated in FIGS. 9 to 11b. For better understanding and visualization, only the tank plate 5 is shown in Figures 10, 11a and 11b. One end of said fill channel 200 opens onto one of the edges of said phase change material reservoir tube 1 so as to be accessible when the phase change material reservoir tube 1 is integrated within a heat exchange bundle 100. The filling channel 200 is formed on the one hand by a filling nozzle 201 and on the other hand by the outer face of one of the two circulation plates 3. filling 200 further comprises a cap 210 which closes and prevents the phase change material from escaping through said filling channel 200. The filling channel 200 and the cap 210 are contained in a volume of width less than or equal to the width of the tube of material with phase change material 1 and height less than or equal to the height of the housings of the phase change material, in particular the cavities 51. As a result, the filling channel 200 does not exceeds the width or height of the phase change material reservoir tube 1. Thus, when said phase change material reservoir tube 1 is integrated within a heat exchange bundle 100, the filling 200 does not exceed and does not interfere.
    [0014] Within a heat exchange bundle 100, it is also advantageous to place the phase change material reservoir tubes 1 so that the filling channel 200 is located in the up position. is the farthest from the ground. In this way, the filling will be facilitated and the risk of leakage at said filling channel 200 will be less.
    [0015] The circulation plates 3 and the reservoir plate 5 are preferably made of metal and are obtained by stamping. The filling spout 201 of the tank plate 5 can thus also be made during the drawing of said tank plate 5. The different plates can thus for example be fixed to each other by soldering. In order to ensure a good fixation and a good seal, the phase change material tank tube 1 may comprise a sealant paste and seal between the filling spout 201 of the tank plate 5 and the plug 210.
    [0016] The filling channel 200 and more precisely the filling spout 201 advantageously comprises an abutment 204 within it. This stop 204 blocks the plug 210 which can not go deeper inside the filling channel 200. The plug 210 preferably has a length less than or equal to the distance 5 between the end of the filling channel 200 and the stop 204 so that said plug 210 does not exceed said filling channel 200. The plug 210 may be made for example of metal. As a result, said metal plug 210 can be soldered in the step where the circulation plates 3 and the tank plate 5 are fixed together by brazing.
    [0017] The plug 210 may also be made of elastomeric or plastic material. In this case, said plug 210 may for example be larger than that of the filling channel 200 so that said cap 210 is compressed inside the filling channel 200. This because of this compression, the sealing at the filling channel 200 is ensured. In the case where the plug 210 is made of elastomeric or plastic material, the latter is preferably inserted into the filling channel 200 after the fixing of the circulation plates 3 and of the reservoir plate 5 between them by brazing. In order to maintain the plug 210 within the filling channel 200, said filling channel 200 may include a retaining tab 202, as illustrated in Figs. 10-11b. The retaining tab 202 is folded over the end of said filling channel 200 opening on one of the edges of the tube of the phase change material tank 1. The plug 210 is thus locked between the stop 205 and the retaining tab 202 as shown in Figure 11b.
    [0018] Preferably, the retaining tongue 202 is made of material with the reservoir plate 5 and can therefore be made simultaneously with said reservoir plate 5, for example by stamping. The plug 210 may also include a fill port 211 as illustrated in Figures 10 to 11c. This filling orifice 211 makes it possible, in particular, to insert phase-change material into the phase change material reservoir tube 1 while the plug 210 is already in place and fixed. When the stopper 211 does not have a filling orifice 211, the phase-change material is for example inserted into the phase change material reservoir tube 1 before the plug 210 is put in place, in particular when the latter is plugged in. is metal. When the plug 210 is of elastomeric or plastic material, the phase change material can be inserted via a needle passing through the plug 210, the elastic properties of the elastomeric or plastic material to close the space created when the needle is removed, the plug thus retaining its seal. When the plug 211 has a fill port 211, the phase change material can be inserted into the phase change material reservoir tube 1 through said fill port 211 after placement and attachment of the plug 210.
    [0019] The retaining tab 202, when folded down, advantageously covers the filling orifice 211 of the plug 210. The retaining tab 202 then closes the filling orifice 211. To ensure better closure and sealing, the tab Maintaining 202 may comprise a projection 203 intended to be inserted at least partially into the filling orifice 211 of the plug 210 when said retaining tab 202 is folded down. Thus, it can be seen that, thanks to the presence of the filling channel 200, the filling of the phase change material reservoir tube 1 made of phase change material is simple and easy to implement. In addition, the limited number of elements makes it possible to limit production costs.
