    [0001] The invention relates to an electrical device for thermal conditioning of a fluid for a motor vehicle. These include an electric heater. The invention applies more particularly to heating and / or air conditioning apparatus for motor vehicles. Usually, the heating of the air for heating the passenger compartment of a motor vehicle, or allowing demisting or defrosting, is ensured by the passage of a flow of air through a heat exchanger, more specifically by a heat exchange between the air flow and a fluid. This is usually the coolant in the case of a heat engine. However, this heating mode may be unsuitable or insufficient to ensure rapid and efficient heating of the passenger compartment of the vehicle, in particular to ensure a warming of the passenger compartment or defrosting or demisting before use of the vehicle in very cold environment or when a very rapid rise in temperature is desired. Moreover, in the case of an electric vehicle, the heating function is no longer performed by the circulation of the coolant in the heat exchanger. A water circuit can be provided for heating the passenger compartment. However, this heating mode may also be inadequate or insufficient to ensure rapid heating and efficient vehicle interior. Furthermore, in order to reduce the size and the cost due to the additional water circuit, it is also known to use for the electric vehicle, an air conditioning loop 25 operating in heat pump mode. Thus, the air conditioning loop conventionally to cool a flow of air with a refrigerant, is in this case used to heat the air flow. It is necessary to do this to use an evaporator of the air conditioning loop as a condenser. However, this mode of heating too may be inappropriate or insufficient. In fact, the performance of the air conditioning loop in the heat pump mode -2 depends on the external climatic conditions. For example, when the outside air has a temperature too low this air can not be used as a source of thermal energy. To overcome these disadvantages of the prior art, a known solution consists in adding to the heat exchanger or the water circuit or the air conditioning loop, an additional electrical device for thermal conditioning of the fluid such as a device electric heating. Such an electric heater may be adapted to heat upstream the fluid, such as the coolant for the engine, or the water for the heating water circuit of the passenger compartment of the electric vehicle or the refrigerant fluid of the air conditioning loop. In known manner, the additional electrical thermal fluid conditioning device comprises one or more thermal modules in contact with the fluid for example to be heated. More specifically, a thermal module may comprise a core and a heating element in the form of an enclosure surrounding the core, in order to define a fluid circulation space between the core and the enclosure. The enclosure, for example cylindrical, is therefore the source of thermal energy. According to a known solution, a heating element has electric heating means, for example one or more heating resistors made by screen printing in the form of resistive tracks on the outer surface of the heating element. Generally, an axial circulation of the fluid in the circulation space between the core and the cylindrical enclosure, decreases the heat transfer between the enclosure and the fluid. In order to increase the efficiency of the heat exchange between the heating element and the fluid flowing between the core and the heating element enclosure, it is therefore preferable to avoid a fluid flow parallel to the axis of the heating element. heating element in the form of a cylindrical enclosure. A known solution is to generate a helical movement of the circulating fluid 30 in the circulation space. This increases the heat exchange between the element -3- heating for example in the form of cylindrical chamber and the fluid flowing inside this cylindrical chamber. To do this, it has been proposed that the core has on its outer surface a substantially helical groove. This helical groove makes it possible to force the spinning of the fluid in order to increase the heat transfer. However, with such a solution it was found a lack of homogeneity of speeds at the entrance of the fluid circulation space and a high pressure drop. According to an alternative solution, it is known in particular from EP2607120 an electrical device comprising one or more thermal modules whose core is made of ceramic and carries a heating element, such a core is arranged inside a chamber surrounding the core. , to define a fluid circulation space between the heating core and the enclosure. Such a technology using a ceramic core is specific. On the other hand, reducing congestion and improving thermal performance are constant problems in the automobile. The invention aims to at least partially overcome the disadvantages of the prior art, by proposing an electrical thermal fluid conditioning device for a simple way to improve thermal performance with a small footprint. To this end, the subject of the invention is an electrical device for thermal conditioning of a fluid for a motor vehicle, said device comprising at least one thermal module comprising: an enclosure comprising at least a first electric heating means, and a core arranged inside the enclosure, so as to define a fluid circulation space between the core and the enclosure, characterized in that the core of a thermal module comprises at least a second electrical heating means of the fluid. This allows a thermal transfer of the second electric heating means to the fluid able to flow in the guide circuit. Thus, with such a thermal conditioning device, the heating of the fluid is carried out both by a thermal transfer of the electric heating means on the chamber to the fluid, and by a heat transfer of the electric heating means provided. on the core immersed in the circulation space of the fluid to be heated towards the fluid. Of course, the two electric heating means can participate together or individually in heating the fluid to be heated. This makes it possible to improve the heat transfer with respect to known solutions having only an electric heating means on the enclosures outside the fluid circulation space or having only an electric heating means on the core immersed in the water. circulation space of the fluid to be heated. With a single thermal module, a thermal efficiency similar to the solutions of the prior art is obtained providing two thermal modules with a single thermal module having a small footprint. According to one aspect of the invention, the core comprises a support of the second electric heating means made of an electrically insulating material and thermal conductor, such as a ceramic material. The second electric heating means may comprise at least one resistive track, and the core may comprise a protective film disposed on the resistive track, and made of an electrical insulating material and thermal conductor, such as a ceramic material. The protective film is for example made of the same material as the support of the second electric heating means. The core thus makes it possible to use the second electric heating means in the circuit of the fluid to be heated by providing electrical insulation with respect to the fluid without altering the thermal performance, since it contributes to the thermal conductivity of the second electrical means of heating. heat carried by the core of the thermal module to the fluid to be heated. According to another aspect of the invention, the enclosure carrying the first electric heating means and the core carrying the second electric heating means are able to be controlled by a common control means, making it possible to obtain a ever more compact structure.
    [0002] According to one embodiment, the core has two terminals capable of being connected to an associated control means, and overmolded in the material of the support of the corresponding core. It is not necessary to provide an interface or additional wiring for the connection of the second electrical heating means carried by the core to the control means. Indeed, the core can be connected directly to the control means via the terminals overmolded in the material of the support, for bringing the current to the second electric heating means. According to another aspect of the invention, the first electrical means is made in the form of resistive tracks on an outer surface of the enclosure out of the circulation space. According to yet another aspect of the invention, said device comprises at least one fluid inlet housing and at least one fluid outlet housing respectively in fluid communication with the fluid circulation space, and arranged in opposite fashion on both sides of the device along a longitudinal axis. This opposite arrangement of the inlet and the outlet of the fluid on either side of the device, along a longitudinal axis of the cores, allows easy integration into the motor vehicle. When this direction is from the bottom upwards, with respect to the integration of the device into a motor vehicle, this reduces the risk of the appearance of air bubbles in the fluid circulation space which can affect the performance of the device. thermal module. According to yet another aspect of the invention, the core comprises on its outer surface at least one groove. The invention also relates to an apparatus for heating and / or air conditioning for a motor vehicle, characterized in that it comprises an electrical device for thermal conditioning of a fluid as defined above.
    [0003] 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 schematically and simpli fi electric fluid heating device according to a first embodiment for a motor vehicle, - Figure 2 is an exploded perspective view of a heating module of the heating device according to the first embodiment of Figure 1, - the Fig. 3a schematically shows a side view of the heater according to the first embodiment of Fig. 1; Fig. 3b schematically shows a side view of a heater according to a second embodiment. and FIG. 4 schematically represents a view from above of the heating device of FIGS. 1 and 3a. In these figures, the identical elements bear the same references. FIG. 1 shows a first embodiment of a device for thermal conditioning 1 of a fluid, such as an electric fluid heating device for a motor vehicle for a heating and / or air conditioning apparatus. The thermal conditioning device 1 is for example an additional heating device for heating a fluid arranged in a heating circuit of a vehicle fluid for heating the passenger compartment. According to one example, the thermal conditioning device 1 is disposed upstream of a heat exchanger of an air conditioning loop capable of operating as a heat pump, so as to heat the cooling fluid. According to yet another example, the thermal conditioning device 1 is arranged upstream of a heat exchanger using the cooling fluid of a heat engine as heat transfer fluid. It would also be possible to provide such a thermal conditioning device 1 upstream of a heat exchanger intended for the thermal regulation of a device for storing electrical energy, sometimes referred to as a set of batteries, or a battery. fuel, for a vehicle with electric or hybrid propulsion. The thermal conditioning device 1 comprises a thermal module 3. In order to control the power supply of the thermal module 3, the thermal conditioning device 1 furthermore comprises at least one control means 10. The thermal conditioning device 1 represented comprises furthermore, a fluid inlet 7, and a fluid outlet 9. With reference to FIG. 2, the thermal module 3 comprises a core 11 and an enclosure 13 surrounding the core 11. The core 11 is therefore arranged inside. of the enclosure 13, it is also referred to as the central core 11. As can be seen more clearly in FIGS. 3a and 4, the central core 11 and the enclosure 13 define a circulation space 15 for the fluid, for example to be heated, between the central core 11 and the enclosure 13. Thus, the outer surface of the central core 11 and the inner surface of the enclosure 13 define a fluid circulation volume, in this example of the fluid to be heated. Referring again to FIGS. 1 and 2, the enclosure 13 is for example made substantially cylindrical in shape, or alternatively of substantially parallelepipedal shape, extending along a longitudinal axis A. The enclosure 13 of the thermal module 3 has two opposite ends: a first end arranged on the side of the fluid inlet 7 and a second opposite end arranged on the side of the fluid outlet 9. The thermal conditioning module 3 thus has a general shape 30 defined by the enclosure 13 which may be substantially cylindrical or substantially parallelepipedal, extending along the longitudinal axis A. The enclosure 13 is adapted to be controlled by the control means 5 so as to heat the fluid by exchange of heat between the chamber 13 and the fluid flowing in the circulation space 15. For this purpose, the enclosure 13, has at least a first electric means 16 for heating 1 heating resistor, carried out schematically in Figure 2. This heating resistor can be made in the form of a resistive track. The resistive track is for example made by screen printing on the outer surface of the enclosure 13, that is to say on the surface opposite to the inner surface of the enclosure 13 facing the central core 11. The track or tracks resistive forming the first electric heating means 16 are therefore out of the circulation space 15 of the fluid to be heated. Thanks to this embodiment, the heat produced by the resistor is transmitted to the fluid to be heated through the wall of the enclosure 13. With reference to FIG. 3a, the enclosure 13 comprises for this purpose two terminals 17 to connect the first electric means 16 for heating to electrical potentials, via the control means 5. The terminals 17 thus make it possible to bring the electric current to the first electric heating means 16. The terminals 17 can be made in the form of flexible tongues adapted to be clipped for example on the control means 5, or else of connection wires that can be welded for example to the control means 5. For this purpose, enclosure 13 has, according to the example of FIG. 2, terminals 16 'of connection electrically connected to the ends of the resistive tracks 16. The control means 5 is electrically connected to these connection terminals 16' via the terminals 17. , it is possible to provide a temperature sensor C for measuring the temperature of the enclosure 13. It may be a thermistor, such as a "CTN" probe for Negative Temperature Coefficient or "NTC" for English "Negative Temperature Coefficient", whose resistance decreases uniformly with temperature. This temperature sensor C can be brazed or welded to the outer surface 30 of the enclosure 13. In this case, the control means 5 controls the supply of the heating resistors according to a heating setpoint and the temperature measured by the temperature sensor.
    [0004] Referring to FIGS. 2 and 3, the central core 11 may in turn be substantially cylindrical in shape and extend along the longitudinal axis A. The central core 11 and the enclosure 13 may be concentric as shown schematically in FIG. Figure 4. The central core 11 of the thermal module 3 has two longitudinally opposite ends: a first end arranged on the side of the fluid inlet and a second opposite end arranged on the side of the fluid outlet. The thermal conditioning device 1 further comprises a second electric heating means 18 carried by the central core 11. The central core 11 also also forms a heating element or heating bar in addition to the heating enclosure 13. The circulation space 15 is thus defined around the second electric heating means or 18 for heating the central core 11. Thus, the heating is also done by immersion of the second electric heating means 18 in the fluid to be heated circulating in the space 15. With this embodiment, the heat produced by the second electric heating means 18 is directly transmitted to the fluid to be heated. The fluid can be heated quickly. The second electric heating means 18 is adapted to be controlled by a control means 5 for heating the fluid flowing in the circulation space 15 by heat exchange between the central core 11 and the fluid in which the central core 11 is immersed. . This is for example a common control means 5 for the second electric heating means 18 carried by the central core 11 and for the first electric heating means 16 carried by the enclosure 13. Thus, the enclosure 13 and the central core 11 may be controlled by the same control means 5. In addition, according to the first embodiment, the outer surface of the central core 11 may be without grooves, so as to define a circulation space. axial parallel to the longitudinal axis A. Indeed, it is not necessary to provide for example a helical flow of the fluid to improve heat transfer because the immersion of the central core 11 also forming a heating body in the fluid volume to heat improves the efficiency. Of course, it is possible according to a second embodiment illustrated in FIG. 3b, that the central core 11 comprises on its external surface at least one groove 12. According to the example illustrated in FIG. 3b, the groove 12 may be substantially 10 helical. In this case, the circulation space 15 defines a substantially helical path for the fluid. This makes it possible to further improve the transfer. In addition, the central core 11 has for example a support 19 of the second electric heating means 18. The support 19 therefore has the function of allowing the arrangement of the second electric heating means 18 in the thermal conditioning device 1, for example for heating as described. The support 19 is made of an electrical insulating material and thermal conductor. The support 19 may have a body 21 and a base or seat 23 at one end 20 of the body 21, more precisely at the first end of the central core 11. The body 21 may be substantially cylindrical in shape and the base 23 for example of substantially circular shape. The body 21 is for example a solid body, such as a solid cylinder. The second electric heating means 18 may for example have at least one electrical resistive track made on the support 19, more precisely on the body 21 of the support 19. In addition, according to the embodiment described, the central core 11 has a protective film (not visible in the figures) disposed on the electrical resistive track. This is for example a flexible film wound around the support 19 so as to protect the or resistive tracks. This protective film is made of a thermal conductive and electrical insulating material. Advantageously it is the same material as the material of the support 19, for example ceramic. The support 19 and the protective film have the additional function of contributing to the heat transfer between the second electric heating means 18 and the fluid around the central core 11. The assembly forming the core 1a or 11b, namely the support 19 and the protective film disposed on the resistive tracks, can be secured by passage in the oven. The central core 11 further comprises two terminals 25 for connecting the second electric heating means 18 to electric potentials, via the control means 10 5. The terminals 25 thus make it possible to bring the electric current to the second electric heating means 18. . The terminals 25 can be made in the form of flexible tongues adapted to be clipped for example on the control means 5, or else of connection son able to be welded for example on the control means 5. The terminals 25 can be for example overmolded in the material for example ceramic support 19. This simplifies the wiring. The support 19 then provides an interconnection function between the second electrical means 18 and the control means 5 via the terminals 25. Thus, the central core 11 provides both a mechanical support function of the second electric heating means 18 , support and protection of the terminals for connection between the second electric heating means 18 and the control means 5, electrical insulation of the second electric heating means 18 vis-à-vis the circulation space 15 of the fluid, and thermal conductivity of the heat of the second electric heating means 18 to the fluid. In addition, the enclosure 13 receiving the central core 11 is arranged around the body 21 of the central core 11 with a distance e shown schematically in Figure 4. It is a distance e lateral to the longitudinal axis A in the illustrated example. This distance e forms a gap between the outer surface of the body 21 of the central core 11 and the inner surface of the enclosure 13 to define the volume of the circulation space 15 and thus delimits a fluid circulation space. . The distance e can be constant over the entire length of the enclosure 13 in the example illustrated, so that the volume of the circulation space 15 is constant. Alternatively, the distance e can be progressive so that the flow velocity is modified along the circulation space 15. In addition, this distance e can be adapted, for example by modifying the diameter of the central core 11, in order to improve thermal performance. Indeed, with a narrow fluid circulation space 15, the fluid flow rate increases, and the speed increases, the pressure drops increase accordingly. And on the contrary, with a circulation space of the fluid to be heated too large, the pressure drops fall but the heat exchange between the fluid and the envelope is not efficient. The distance range e between the body 21 of the central core 11 and the enclosure 13 is chosen so as to define a volume of the circulation space 15 which provides a satisfactory heat exchange while minimizing pressure losses. The volume of the circulation space 15 thus defined is sufficiently small for the fluid to pass sufficiently quickly and absorb heat and sufficiently large for the pressure losses to decrease. According to the embodiment illustrated in FIGS. 1, 3a and 3b, the control means 5 is, for its part, arranged on one side of the thermal conditioning device 1. As previously mentioned, the control means 5 may be common for the two electric heating means 16 and 18 carried on the one hand by the central core 11 and on the other by the enclosure 13. The control means 5 may comprise at least one electrical circuit support such as that a printed circuit board 31, PCB in English for "Printed circuit board". The control means 5 comprises, in particular, electronic and / or electrical components carried by the electrical circuit support 31. These electronic and / or electrical components may for example comprise a microcontroller and electrical contacts connected to the first electric heating means 16 provided for on the enclosure 13 or the second electric heating means 18 provided on the central core 11. The control means 5 may further comprise at least one power switch 33.
    [0005] As said above, the thermal conditioning device 1 further comprises at least one fluid inlet 7 for the admission of the fluid and at least one fluid outlet 9 for the evacuation of the fluid. According to the illustrated example, the fluid inlet 7 may comprise a fluid inlet casing 35. According to the example illustrated in FIG. 3a or 3b, the power switch 33 may be arranged close to the casing fluid inlet 35, being in thermal contact with the fluid inlet housing 35 thus allowing cooling of the power switch 33, by heat exchange with the fluid entering the device 1. The fluid inlet housing 35 is fixed to the enclosure 13. A sealing means 36 may be disposed between the fluid inlet housing 35 and the enclosure 13 (see Figure 3a or 3b). The sealing means 36 is for example arranged at a longitudinal end of the chamber 13. In addition, the central core 11 can be assembled by its base 23 to the fluid inlet box 35. A means of Sealing 37 may be arranged between the base 23 of the central core 11 and the fluid inlet housing 35. Further, a fluid inlet pipe 38 is provided in the fluid inlet housing 35. The tubing For example, the inlet 38 is arranged projecting from the fluid inlet housing 35. The inlet pipe 38 extends in the illustrated manner substantially radially with respect to the longitudinal axis A of the thermal module 3. According to FIG. the illustrated example, the fluid inlet housing 35 has a fluid inlet channel 39 in fluid communication with the inlet manifold 38 and with the circulation space 15 of the thermal module 3. This allows the circulation of the fluid 30 from the inlet pipe 38 to the space of 15 as shown schematically by the arrows in FIG. 3a or 3b. Similarly, for the fluid outlet 9 can be provided a fluid outlet housing 41.
    [0006] This fluid outlet box 41 is fixed to the enclosure 13. According to the embodiment illustrated in FIGS. 1, 3a and 3b, the fluid outlet box 41 is arranged opposite to the inlet box of the housing. fluid 35. A sealing means 42 is advantageously provided between the enclosure 13 and the fluid outlet box 41.
    [0007] The fluid outlet box 41 comprises a fluid outlet pipe 43. The outlet pipe 43 is for example arranged protruding with respect to the fluid outlet housing 41. More specifically, the outlet pipe 43 extends in accordance with FIG. illustrated example substantially perpendicular to the longitudinal axis A of the thermal module 3.
    [0008] Of course, other arrangements are possible. By way of example, the fluid outlet box 41 and the fluid inlet box 35 can be arranged on the same side of the thermal module 3, or the inlet and outlet pipes 38 and 43 can be arranged. on the same side or on two opposite sides, or the outlet pipe 43 for example may extend in a direction substantially parallel to the longitudinal axis A. According to the illustrated example, the fluid outlet housing 41 has a fluid outlet channel 45 in fluid communication with the circulation space 15 of the thermal module 3 as well as with the fluid outlet tubing 43. Thus, the fluid from the fluid inlet casing 35 can flow through the fluid outlet channel 45. fluid inlet channel 39 and then in the circulation space 15 of the thermal module 3, before being discharged while circulating in the fluid outlet channel 45 and then through the outlet pipe 43. A thermal conditioning device 1 and realized p It can limit the pressure drop by having a smaller footprint compared to some of the solutions of the prior art, while increasing the transfer of calories. Indeed, the central core 11 according to the first or second embodiment forms according to the invention also a heating element or heating bar in addition to the heating chamber 13 in which is arranged the central core 11.
    [0009] The heat generated by the second electric heating means 18, for example made in the form of resistive tracks, is directly transmitted to the fluid in which the central core 11 is immersed. In addition, the heat produced by the first electric heating means 16 is also transmitted to the fluid through the wall of the enclosure 13. The heat transfer is thus accumulated between the first electric heating means 16 carried by the enclosure 13 and the fluid inside the chamber 13 around the central core 11, and the heat transfer between the second electric heating means 18 carried by the central core 11 and the fluid around the central core 11. Of course, the first means 16 and the second electric heating means 18 can participate together but also individually to the heating of the fluid to be heated. Thus, with a single thermal module 3 comprising a single heating enclosure 13 and a single heating core 11, it is possible to obtain a heating power similar to the power obtained in the solutions of the prior art providing for two thermal modules, with a compact structure .
