    [0001] The present invention relates to the thermal regulation in a vehicle and more specifically to a heat exchanger and the corresponding thermal management device.
    [0002] In order to regulate the temperature of elements, for example batteries within an electric or hybrid motor vehicle, it is known to attach them a heat exchanger connected to a thermal management circuit and this as well to cool these elements that the warm up if necessary.
    [0003] The thermal regulation of batteries in the automotive field and even more particularly electric and hybrid vehicles, is an important point because if the batteries are subjected to temperatures that are too cold, their autonomy can decrease sharply and if they are subjected to too high temperatures there is a risk of thermal runaway that can lead to the destruction of the battery. In order to regulate the temperature of the batteries, it is known to add a thermal management device of the battery module. These devices generally use circulating heat transfer fluids, for example by means of a pump, in a conduit circuit, said conduit circuit passing in particular under or inside a heat exchanger in direct contact with the batteries. Heat transfer fluids can thus absorb heat emitted by the battery (s) in order to cool them and evacuate this heat at one or more heat exchangers such as for example a radiator or a refrigerant. The heat transfer fluids may also, if necessary, provide heat to heat said batteries, for example if they are connected to an electrical resistance or heating by Positive Temperature Coefficient (PTC).
    [0004] The heat transfer fluids generally used are ambient air or liquids such as water. Liquids are better heat conductors than gases, it is a solution that is preferred because more effective. Nevertheless, it may be difficult to fix and connect these different elements, and in particular a heat exchanger, to the thermal management circuit, which can have an impact on the assembly and manufacturing times. Thus, it is an object of the present invention to provide a heat exchanger as well as the thermal management device associated with improved connections and connections. The present invention therefore relates to a heat exchanger comprising: - flat tubes placed parallel to each other, - a first and a second heat transfer fluid collectors each respectively placed at one end) of the flat tubes, the first collector being divided into at least one proximal portion, comprising at least one first peripheral tube, and to which is connected a heat transfer fluid inlet and a distal portion to which is connected a heat transfer fluid outlet and comprising at least a second peripheral tube distinct from that of the proximal portion, said portions being separated by at least one screen placed within said first collector between two ends of flat tubes, blocking the circulation of coolant between said two flat tubes within said first collector, the heat exchanger further comprising a connection system attached to the first collector and having a a power supply connected to the heat transfer fluid inlet of the proximal portion of the first manifold and an exhaust connector connected to the coolant discharge of the distal portion of the first manifold. The presence of this connection system, including both the arrival and discharge of heat transfer fluid, facilitates the connection and mounting of the heat exchanger within a thermal management device.
    [0005] According to one aspect of the invention, the connection system is fixed on one end of the proximal portion of the first manifold, the supply connector opening into the proximal portion of the first manifold and the exhaust connector being connected to the evacuation heat transfer fluid of the distal portion of said first manifold by means of a connector.
    [0006] According to another aspect of the invention, the first collector and the connection system are made of a metallic material and that their fixing is carried out by brazing.
    [0007] According to another aspect of the invention, the connection system comprises a prepositioning slot within which the proximal peripheral tube is inserted at least partially. According to another aspect of the invention, the connection system comprises at least one retaining finger.
    [0008] The retaining finger allows in particular a maintenance of said connection system during connections. According to another aspect of the invention, the flat tubes have their flat surfaces parallel to the axis of the first and second collectors. According to another aspect of the invention, the power connector and the discharge connector have a different connection conformation from each other.
    [0009] This different conformation plays a key role to avoid branching reversals. The present invention also relates to a thermal management device comprising a thermal management circuit in which circulates the heat transfer fluid and comprising a heat exchanger as described above. According to one aspect of the device according to the invention, the latter further comprises a connection system to the heat exchanger, complementary to the connection system and comprising: a first connector connected to the thermal management circuit via a supply channel said first connector is connected with the supply connector in a sealed manner so as to supply the heat exchanger with heat transfer fluid; a second connector connected to the thermal management circuit via an evacuation channel, said second connector being connected with the discharge connector sealingly so as to evacuate the heat transfer fluid having passed through the heat exchanger. According to another aspect of the device according to the invention, the supply and discharge connectors 5 are orifices and that the first and second connectors are nozzles that are engaged in said orifices. According to another aspect of the device according to the invention, the fixing between the connection system and the connection system is carried out by means of at least one screw. According to another aspect of the device according to the invention, said device comprises seals placed around the end pieces of the first and second connectors. Other features and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings in which: FIG. 1 shows a schematic representation in perspective 20 of a portion of a heat exchanger according to the invention, - Figure 2 shows a diagrammatic representation in exploded perspective of a connection between a heat exchanger and a thermal management circuit, - Figure 3 shows a schematic representation in perspective sectional view of a heat exchanger according to the invention at a collector, - Figure 4 shows a schematic representation in perspective and in section of a connection between a heat exchanger and a thermal management circuit, - the FIG. 5 shows a diagrammatic perspective view of a heat exchanger according to the invention at a collector at a diagonal angle of view. FIG. 6 shows a schematic representation in plan view of a heat exchanger according to the invention installed between two batteries, and FIGS. 7a and 7b show schematic representations for cutting heat exchangers in two modes of achievement. The identical elements in the different figures bear the same references. As shown in FIG. 1 showing a schematic perspective representation of a portion of a heat exchanger 1 according to the invention, the latter comprises: flat tubes 3 placed parallel to each other, first and second second collectors 5 (only the first collector is visible here) of heat transfer fluid respectively placed at one end 31 of the flat tubes 3.
    [0010] The first collector 5 comprises at least one proximal portion 5a, comprising at least a first peripheral tube 3a, to which is connected a heat transfer fluid inlet. By peripheral tube is meant a flat tube 3 which is located at the top or bottom at one end of the arrangement of flat tubes 3. The first manifold also comprises a distal portion 5b which is connected to a coolant discharge and comprising at least one second peripheral tube 3b distinct from that of the proximal portion 5b. Parts 5a, 5b are separated by at least one screen 7 placed within said first manifold 5 between two ends of 31 flat tubes 3. This screen 7 blocks the circulation of coolant between said two flat tubes 3 within said first collector 5. In the example shown in FIGS. 1 and 3, and more particularly in FIG. 7a, the first collector 5 comprises a single screen 7. The coolant 15 thus arrives in the proximal portion 5a and passes through the flat tubes 3, including the first peripheral tube 3a, which are upstream of the screen 7. The fluid then passes into the second manifold (which here does not include screen) and passes into the flat tubes 3, including the second peripheral tube 3b, located downstream of the screen 7. It is however quite possible to imagine an embodiment where the first collector 5 comprises several screens 7 defining a plurality of other parts and where the second collector also includes in order to increase the number of heat transfer fluid passes between the proximal portion 5A and the distal portion 5b. this embodiment is for example illustrated in Figure 7b. 25 Whether in one case or the other, the arrival of heat transfer fluid and its evacuation is at the same collector 5.
    [0011] The heat exchanger 1 further comprises a connection system 11 fixed to the first collector 5. This connection system 11 comprises in particular a supply connector i3a connected to the heat transfer fluid inlet of the proximal portion 5a of the first collector 5 and a discharge connector 13b connected to the coolant discharge of the distal portion 5b of the first manifold 5. The presence of this connection system 11, including both the arrival and discharge of coolant, allows for facilitate the connection and mounting of the heat exchanger within a thermal management device. The power connector i3a and the discharge connector 13b may have a branching configuration that is different from each other. This different connection conformation plays a key role in order to facilitate the connection of the heat exchanger 1 with the thermal management device. For example, the power supply connectors 13a and 13b can both be circular with different diameters as shown in the various figures. The connection system 11 can be fixed on one end of the proximal portion 5a of the first collector 5, the supply connector i3a 20 then opening into the proximal portion 5a of the first collector 5 and the discharge connector 13b being connected to the discharging heat transfer fluid from the distal portion 2b of said first collector 5 by means of a connector 9. In the examples presented in the various figures, the heat exchanger 1 is a heat exchanger intended to come into contact with at least one a battery 100 for heating or cooling according to the conditions and needs (see Figure 6). Thus, in order to facilitate contact with the battery or batteries 100, the flat tubes 3 have their flat surfaces parallel to the axis of the first and second collectors 5. In this type of battery thermal management device, the heat transfer fluid used can in particular, 1,1,1,2-tetrafluoroethane (Rima), 2,3,3,3-tetrafluoropropene (R1234ye or carbon dioxide (R744), the first manifold 5 and the connection system 11 may be made of a metallic material and therefore can be fixed by brazing, the connection system 11 may also include a prepositioning slot 33, as illustrated in FIG. is inserted at least partially.This prepositioning slot 33 allows in particular optimal positioning of the connection system 11 relative to the first collector 5 and flat tubes and also a certain maintenance during the attachment of said connection system 11. The heat exchanger 1 is intended to come to connect with a thermal management device 15 comprising a thermal management circuit in which circulates the heat transfer fluid. As illustrated in FIGS. 2 to 5, said thermal management device may further comprise a connection system 21 to the heat exchanger 1 complementary to the connection system 11 and comprising: a first connector 23a connected to the management circuit by a supply channel 25a, said first connector 23a connecting with the supply connector i3a sealingly so as to supply the heat exchanger 1 with heat transfer fluid, - a second connector 23b connected to the thermal management circuit by a discharge channel 25b, said second connector 23b connecting with the discharge connector 13b in a sealed manner so as to evacuate the coolant having passed through the heat exchanger 1.
    [0012] According to a preferred embodiment and illustrated in Figures 1 to 4 the power supply connectors 13a and discharge 13b are orifices and the first 23a and 23b second connectors are end pieces engaged in said orifices. In order to seal the connection, the device may comprise seals placed around the ends of the first 23a and second 23b connectors. The connection system 11 and the connection system 21 are attached to each other to provide good connection and strength to the assembly.
    [0013] This attachment can be achieved by means of at least one screw 27 passing through the connection system 21 and coming into a tap hole 17 placed on the connection system 11. The connection system 11 can also comprise at least one finger 15 as shown in the various figures. This retaining finger 15 is placed so as to abut against an element, more particularly against one or two batteries 10o, as illustrated in FIG. 6, in order to avoid the rotational movements during the fixing of the connection system 21. on the connection system. Thus, it is clear that because the supply and discharge of the heat transfer fluid is at the same collector and also because of the presence of a connection system, the connection of the heat exchanger is facilitated, and all the more so if the thermal management device comprises an additional connection system.
