    Field of the invention
    The invention relates to a power supply module for a heating radiator and a heating radiator comprising such a power supply module. It is in particular intended for the equipment of air conditioning units, in particular of motor vehicles.
    State of the art
    Heating radiators for motor vehicles, and in particular motorized vehicles by means of an electric or hybrid motor conventionally comprise a heating body in which is installed a plurality of heating elements supplied with current from a power supply module integrated in the heating radiator. These heating elements are capable of heating a flow of air sent into the passenger compartment of the motor vehicle after passing through the heating body.
    In known devices, the power supply module generally comprises a printed circuit board which extends transversely relative to the extension plane of the heater body, adjacent to a proximal edge of said heater body. When the heating radiator is integrated into the housing located under the dashboard of a vehicle, the heating body is completely inserted in the space provided for this purpose in the housing, while the power module protrudes from the housing.
    Conventionally, the printed circuit board is connected to one or more control elements and / or connectors to the heating body and / or to external circuits, the distribution of which varies according to different configurations. As analyzed by the applicant, these configurations must meet different constraints. First, they must have a limited size, this in combination with the size of the heating body. They must also promote the dissipation of the heat given off by the control elements. They must also allow a simple spatial distribution of the conductive tracks located at the level of the printed circuit board ensuring the electrical connection between the electronic components used and said printed circuit board.
    There is still a need for improvement in this area.
    To this end, according to a first aspect, the invention provides a heating radiator comprising a power module and a heating body, said power module comprising a printed circuit board, a plurality of electronic switches and one or more connectors to an external circuit, said printed circuit board comprising a first zone ensuring an electrical connection with the heating body, a second zone ensuring an electrical connection with the electronic switches and a third zone ensuring an electrical connection with the connector (s), said first, second and third zones being located side by side in this order in a direction transverse to an extension plane of the heating body.
    We have a kind of power module in which the switches remain close to the heating body, which will facilitate the dissipation of the heat they give off, in particular by the use of a dissipator placed in the air flow intended to pass through the heating body.
    Such a power supply module also makes it possible to limit the bulk by placing its different zones side by side in the same direction. A substantially planar configuration is thus obtained in this way.
    By "substantially planar" is meant that the power supply module has a small thickness in the extension plane of the heating body, and that it develops in a transverse plane, in particular perpendicular, to said heating body. In other words, the supply module has a small dimension along a longitudinal axis X of the extension plane of the heater body, a dimension substantially similar to the heater body along a axis Y transverse to the longitudinal axis X in the plane d extension of the heating body and a dimension suitable for the side by side dimensioning of the first, second and third zones, along an axis Z transverse to the axes X and Y.
    In addition, the distribution of the elements of the power supply module into separate zones, which are moreover positioned side by side, simplifies the spatial distribution of the tracks of the printed circuit board.
    According to different characteristics of the invention which can be taken together or separately:
    - said third zone extends in a middle zone so as to give the printed circuit board a T-shaped configuration;
    - Said third zone forms a longitudinal branch of the T and the first and the second zone form a transverse branch of the T;

    - the electronic switches extend on either side of the third zone;
    - Said heating radiator comprises a dissipator extending parallel to the extension plane of the heating body, so as to allow dissipation of the heat given off by said electronic switches by a flow of air passing through the heating body;
    - a first of the connectors is a low voltage connector;
    - the second of the connectors is a high voltage connector.
    the third zone comprises a zone of low voltage components, grouped together and connected to the low voltage connector;

    detailed description
    With reference to FIGS. 1a to 1c, the invention relates to a heating radiator 1 comprising a supply module 2 and a heating body 3, intended to be traversed by an air flow F.
    It is, for example, a heating radiator, called high voltage, that is to say intended to be supplied by a current greater than 60 V, in particular between 60 and 1000 V, more particularly between 180 and 600 V, and / or allowing to release a power higher than 2 KW, in particular between 2 kW and 10 kW. Thus, in the case of a heating radiator for a motor vehicle, the air flow F can be heated by passing through the heating body 3 to increase the temperature in the passenger compartment of the vehicle.
    As can be seen better in FIG. 1a, said heating body 3 extends in an extension plane, called the heating body extension plane, comprising a longitudinal axis X and a transverse axis Y, said transverse axis Y being orthogonal to the X axis. Said heating body 3 here has a substantially parallelepiped configuration, extending in said extension plane of the heating body. It is intended to be positioned transversely to the air flow F to be heated. More specifically, said air flow F is intended to be oriented perpendicular to said heating body 3, that is to say perpendicular to the plane of FIG. 1a.
    Said heating body 3 comprises heating elements, not shown. The heating elements are, for example, PTC effect resistors (for positive temperature coefficient). The said heating element (s) are located inside one or more tubes or housings 30 of the said heating body 3 to electrically isolate the said heating element (s) from the outside.
    The housings 30 form with the heating elements heating units. Said heating units are selectively supplied with current. By this is meant that each heating unit is supplied with current independently of the others and can therefore be traversed by a different current, in particular by its intensity, from the current flowing through the other heating units. The value of the current involved here is in particular the value of the average current or the effective current.
    Said heating elements are electrically connected in parallel, in particular by means of electrodes 32 (visible in FIG. 3a) located at their ends. Preferably, said heating elements are distributed regularly along said housings 30.
    The heating body 3 may also include heat sinks 33, for example fins, in relation to thermal contact with the heating elements. The heatsinks 33 are positioned, in particular, between said housings 30.
    Said heating body 3 comprises a frame 4, in particular made of plastic, accommodating said heating units. Said frame 4 comprises two opposite lateral edges 5 and 6 as well as a proximal edge 7 and an opposite distal edge 8, said proximal edge 7 and said distal edge 8 joining the lateral edges 5 and 6, for example by their ends. Said frame 4 is preferably provided with reinforcements extending transversely between the two lateral edges 5 and 6 of the frame. The housing (s) 30 extend longitudinally from the proximal edge 7 to the distal edge 8. The frame 4 is fixed to the supply module 2, and in particular to a housing 10 of said supply module 2.
    Said housing 10 comprises two opposite lateral edges 11 and 12 as well as a proximal edge 16, situated opposite the proximal edge 7 of the heating body 3, and an opposite distal edge 15. Said proximal edge 16 and said edge distal 15 of the supply module 2 extend transversely, in particular perpendicularly, to the extension plane of the heating body.
    As can best be seen in FIG. 1b, the proximal edge 16 and the distal edge 15 of said feed module 2 are separated by a distance d1. Said distance d1 is the smallest dimension of the supply module 2, that is to say that said distance d1 corresponds to the thickness of said supply module 2. By way of comparison, the distance d1 is substantially equivalent to a distance d2 separating a first large face 9 and a second large face 9 'of the heating body 3, said distance d2 being the thickness of the heating body 2. In other words, and in relation to FIG. 1a, the power supply module 2 therefore has a small dimension in the extension plane of the heating body.
    In FIG. 1c, said power module 2 can be seen in an extension plan, called the power module extension plan. Said power module extension plane comprises the longitudinal axis X and a transverse axis Z orthogonal to the X axis and to the Y axis. In other words, said power module extension plane extends transversely to said heating body extension plane.
    As illustrated, again, in FIG. 1c, the opposite lateral edges 11 and 12 of the supply module 2 are separated by a distance d3, corresponding to the height of the supply module 2, while the lateral edges 5 and 6 of the heating bodies 3 are separated by a distance d4, said distance d4 corresponding to the height of the heating body 3. Said distances d3 and d4 preferably differ by less than 20%, and even more preferably by less than 10%. In other words, the power supply module 2 has a height equivalent to that of the heater body 3.
    With reference to FIGS. 2a to 2c, the heating radiator 1 according to the invention is illustrated in a front view without the heating body 2 (Fig. 2a and 2b) and with the heating body 2 (Fig. 2c). As illustrated in FIG. 2c, the heating radiator corresponds to the heating radiator in FIG. 1c without part of the housing 10 of the power supply module 2 (only one remaining a cover of said housing).
    The housing 10 of the power supply module 2 accommodates a printed circuit board 20 extending transversely, in particular perpendicularly, to the extension plane of the heating body. By printed circuit board 20 is meant a plate making it possible to support and electrically connect a set of electronic components to each other. For this purpose, the printed circuit board 20 includes a set of conductive tracks for connecting said electronic components. Said printed circuit board 20 occupies an appropriate surface in the housing 10, that is to say that its entire surface is included in the housing 10, so that it is protected from the external environment. Here, she follows its contours.
    According to the invention, said printed circuit board 20 comprises a first zone 200 ensuring an electrical connection with the heating body 3, a second zone 210 ensuring an electrical connection with electronic switches 21 and a third zone 220 ensuring an electrical connection with one or more connectors 22 to one or more external circuits, said first, second and third zones being located side by side in this order in a transverse direction, in particular perpendicular, to an extension plane of the heating body
    2. In other words, the first zone 200 is adjacent to the second zone 210, the second zone 210 is adjacent to the third zone 220, while the first zone 200 and the third zone 220 are not adjoining. In other words, the second zone 210 is interposed between said first and third zones.
    By placing said first, second and third zones side by side, the printed circuit board 20 is partitioned, that is to say that said printed circuit board 20 is divided into several zones, which moreover are zones having functionalities. distinct. This improves the distribution of the conductive tracks on the printed circuit board 20 by avoiding overlapping between tracks having different attributes.
    Furthermore, the positioning of said first, second and third zones previously described in the same plane, therefore allows the power supply module 2 to have a substantially planar configuration in the extension plane of the heater body and to limit its size, so that when the heating radiator 1 is inserted into the housing provided for this purpose under the dashboard, the power supply module 2 extends beyond the housing only over the distance d1 (visible in FIG. 1b).
    More precisely, the first zone 200, delimited by the dotted rectangle situated on the right in FIGS. 2a to 2c, is located opposite the heating body 3. In fact, as can be seen more clearly in the figure 2c, said first zone 200 is masked by the heating body 3, so that it faces the proximal edge 7 of said heating body 3. In such a configuration, the electrodes 32 (visible in FIG. 3a) located at the ends heating elements open into the housing 10 directly opposite the first zone 200.
    The power supply module 2 advantageously comprises a connector member 201 making it possible to connect said electrodes 32 to the printed circuit board 20. Said connector member 201 is subject to said first zone 200, that is to say that it extends entirely within the first zone 200 and is fixed on said first zone 200.
    Advantageously, said connector member 201 comprises a frame 203 and connector elements 204. The frame 203 is subject to the first zone 200 and extends perpendicular to the printed circuit board 20. Said frame 203 (visible from side in FIG. 3b) corresponds to the outline of said connector member 201 and makes it possible to position the connector elements 204 on the printed circuit board 20. Said connector elements 204 are connected to the printed circuit board 20 and molded into said frame 203. By "Overmolded" means that said connector elements 204 are molded in the frame 203, said frame being itself molded. Said connector elements 204 are located opposite the electrodes 32, so as to be in direct contact with the electrodes 32 emerging at the level of the first zone 200.
    As illustrated in FIG. 2b, the connector member 201 is advantageously surmounted by an electrically insulating plate 205, so that said plate 205 faces the first zone 200 in the extension plane of the heating body 3.
    In the second zone 210, delimited by the central dotted rectangle in FIGS. 2a to 2c, the electronic switches 21 are aligned in a direction parallel to a direction of extension of said frame 203. In other words, the electronic switches 21 are distributed along the connector member 201 and parallel to said connector member 201.
    The electronic switches 21 within the meaning of the invention are electronic power components making it possible to independently control the current flowing in each heating unit, from a control signal. So these are controlled switches. Preferably, the electronic switches 21 are insulated gate bipolar transistors (IGBT) or metal oxide gate field effect transistors (MOSFET). Such switches are particularly suitable when the power supply to the heating radiators is high. The examples mentioned above are non-limiting and other types of electronic switches can be envisaged to supply current to the heating body 3.
    When the heating radiator 1 is supplied with voltage, the electronic switches 21 are caused to heat up and are then capable of giving off heat. This heat must therefore be dissipated in order to avoid overheating of the power supply module 2.
    Thanks to the arrangement of the zones in accordance with the invention, the power supply module 2 is configured so that the electronic switches 21 remain close to the heating body 3. In fact, as illustrated in FIG. 2c, the electronic switches 21 are advantageously placed in the immediate vicinity of the heating body 3. Such a configuration makes it possible to facilitate the dissipation of the heat released by said electronic switches 21, in particular by the use of a thermal conductor placed in the air flow F intended for pass through the heating body.
    To this end, the heating radiator 1 comprises a dissipator 25 extending parallel to the extension plane of the heating body 3. The dissipator 25 is in direct contact with the electronic switches 21, which allows it to exchange heat. heat with said electronic switches 21 by conduction, then dissipate the heat given off by said electronic switches 21 by the air flow F passing through the heating body 3. Thus, advantageously the heat generated by the electronic switches 21 and dissipated in the heating body 3 by means of the dissipator 25 can contribute to the heating of the air flow F passing through the heating body 3.
    As illustrated in the dotted rectangle on the left in FIGS. 2a to 2c, the third zone 220 preferably extends in a middle zone, so as to give the printed circuit board 20 a T-shaped configuration. More precisely, the first and the second zone 200, 210 form a transverse branch of the T, while the said third zone 220 forms a longitudinal branch of the T. It will also be understood that the electronic switches 21, located in the second zone 210, adjacent to the said third zone 220, extend on either side of said third zone 220, that is to say that said switches 21 extend from the lateral edges of the longitudinal branch of the T in a direction parallel to the transverse branch of T.
    As can be seen in FIG. 2a, the third zone 220 covers a surface which extends between lateral edges 17 and 18 of the longitudinal branch of the T.
    Advantageously, the connector or connectors 22 to one or more external circuits of the power supply module extend from lateral edges 17, 18 of the longitudinal branch of the T in a direction parallel to the transverse edge of the T. In other words , the connector or connectors 22 extend parallel to the transverse branch of the T on each side of the longitudinal branch of the T. Preferably, the connector or connectors 22 do not extend beyond the lateral edges 11, 12 of the housing 10 said feed module 2. This is facilitated in particular by the middle position of the third zone 220 and allows the feed module 2 to keep a limited height d3.
    Advantageously, a first connector 22a of said connectors is a low voltage connector and a second connector 22b of said connectors is a high voltage connector. To this end, as illustrated in FIGS. 2a to 2c, said third zone 220 comprises a zone 221 of low voltage components, grouped together and connected to the low voltage connector 22a, and a zone 222 of high voltage components, grouped together and connected to the high voltage connector 22b. This advantageously makes it possible to improve the spatial distribution of the components in said third zone 220 according to their functionalities.
    An optimized heating radiator 1 is thus obtained by grouping the functionalities of the supply module 2 into separate zones and distributed in an appropriate manner, using the heat released by the components of said supply module 2 in the flow of air passing through. the heating body 3 and having a slight extension outside the housing located under the dashboard of a vehicle.
    The invention also relates to the power supply module 2 of the heating radiator according to one of the preceding claims.
