    BOXING ASSEMBLY FOR ELECTRICAL EQUIPMENT
    The present invention relates to a housing assembly for electrical equipment, and electrical equipment comprising an assembly according to the invention, in particular for applications in the automotive field.
    An inverter is known for controlling an electrical machine embedded in a vehicle. The machine on board the vehicle can drive the wheels of the vehicle. Such an inverter may comprise an electronic power unit comprising components through which the energy supplying the electric machine passes; and an electronic control unit comprising components for controlling the components of the power electronics unit.
    Also known DC / DC voltage converters embedded in a vehicle that perform a voltage conversion between a first electrical network and a second electrical network of the vehicle. Typically, the first power grid is a low voltage network delivering a voltage below 60V, in particular about 18 or 12V, and the second power grid is a high voltage network that delivers a voltage greater than 60V, in particular greater than 100, 200, even 400V. In order to gain density of integration into the vehicle, the inverter and the DC / DC converter can be integrated into a single electrical equipment inside the vehicle. The inverter and the DC / DC converter undergo a temperature rise related to their environment, but which is also related to the high power that flows through them when the electrical machine is operating at high voltage or when the DC / DC converter performs a high conversion. low tension.
    In order to obtain efficient cooling of the inverter and the DC / DC converter, it is known to provide a two-piece electrical equipment box in which the components of the inverter and the DC / DC converter are distributed between the two components. two parts, a cooling circuit being provided between the two housing parts. For example, patent publication KR20110139038 A discloses such an electrical equipment package in which a first housing comprises the components of the inverter and a second housing comprises the components of the DC / DC converter. A wall of the first housing is against a wall of the second housing to define channels for circulating a cooling fluid.
    However, the realization of such a two-part housing is complex and raises problems related to the holding of the sealing of the cooling circuit or the integration of the components in the housing in two parts. The invention seeks to solve at least in part the problems of the prior art by providing a housing assembly for electrical equipment, said assembly comprising: - a first housing for receiving at least a first electronic component of said electrical equipment; a second housing intended to receive at least a second electronic component of said electrical equipment; - A cooling circuit configured to receive a fluid for cooling said electrical equipment, said cooling circuit being formed at least in part by a first wall of the first housing and a second wall of the second housing bearing against one against the other; wherein the first wall and the second wall respectively comprise at least one groove, the groove of the first wall and the groove of the second wall being intended to come face to face to form at least partly said cooling circuit.
    In the prior art, the cooling circuit is formed by a more or less wide groove in a first of the walls, while the second wall has a flat surface which faces the first wall. The second wall may include pins that extend from its flat surface into the groove of the first wall. However, the second wall does not include a groove in its flat surface which comes opposite the groove of the first wall to form the cooling circuit. In the assembly according to the invention, coming opposite one another, the grooves together form a channel of the cooling circuit. Thus, the diameter of the cooling channel is distributed between the two walls. This makes it possible to distribute between the two walls the stresses on the wall thickness which are due to the formation of the cooling circuit. Thus, in the invention, the first wall has a throat less deep than in the prior art, which allows to provide a lower first wall thickness. At housing height constant with respect to the prior art, there is therefore more room for housing the first component or components in a space defined by the first housing, in particular a space which extends in a direction perpendicular to the first wall, in particular a space delimited by lateral walls of the first housing which extend in a direction transverse to the first wall, from the periphery of the first wall.
    According to one embodiment, each wall is an integral part.
    According to one embodiment, each wall comprises a substantially flat surface, said support surface; said bearing surfaces being intended to bear against each other to form at least partly the cooling circuit, each bearing surface comprising the edges of the respective groove of the wall.
    According to one embodiment, each wall is devoid of protrusion extending beyond said bearing surfaces at least in a respective zone of the walls which forms the cooling circuit.
    According to one embodiment, the assembly further comprises a seal between the first wall and the second wall to seal said cooling circuit, and the seal is configured to seal around the respective areas. walls that form the cooling circuit.
    According to one embodiment, the first housing comprises side walls extending from the first wall so as to form a housing for receiving the first electronic component or components, the first wall forming a bottom of said housing; and / or the second housing comprises side walls extending from the second wall so as to form a housing for receiving the second or electronic components, the second wall forming a bottom of said housing.
    According to one embodiment, the first wall is configured to receive the at least one first electronic component and / or the second wall is configured to receive the at least one second electronic component, in particular on a surface of the respectively first or second, wall that is opposite the throat.
    According to one embodiment, an input port and an output port of the cooling circuit are included in one of the two boxes.
    According to one embodiment, the first and second walls respectively comprise at least one through hole whose edges come into correspondence to form a passage for an electrical connection between the first and the second components. The invention also relates to an electrical equipment comprising: - an assembly according to the invention, - at least a first electronic component housed in the first housing, - at least a second electronic component housed in the second housing.
    According to one embodiment, the electrical equipment comprises: - switches of an inverter and / or switches of a DC / DC voltage converter housed in the first housing; and filtering and rectifying components housed in the second housing. The invention will be described in detail in the following description in conjunction with the accompanying drawings. It should be noted that these drawings have no other purpose than to illustrate the text of the description and do not constitute in any way a limitation of the scope of the invention.

    Figures 13 and 14 are perspective views of the second housing of the assembly.
    Figures 1 and 2 show perspective views of an example of electrical equipment 1 according to the invention. The electrical equipment includes a set 100 which houses the components of the electrical equipment 1. The electrical equipment 1 comprises in particular an inverter intended to power an electrical machine such as a rotating electrical machine, for example a machine intended to drive the electrical equipment. wheels of a vehicle. The electrical equipment includes a DC / DC converter for converting a voltage between a first DC grid and a second DC electrical network of the vehicle. The housing assembly 100 of the electrical equipment 1 comprises a first box 110 and a second box 120. The first box 110 receives one or more first components of the electrical equipment 1, illustrated for example in FIGS. 3 and 5 to 7. The second housing 120 receives one or two second electrical components, illustrated for example in Figures 4 and 5.
    Examples of first 110 and second 120 housings are illustrated in FIGS. 8 to 14. The first housing 110 comprises a first wall 111 which bears with a second wall 121 of the second housing 120 to form a cooling circuit 200 of the equipment 1. The cooling circuit 200 receives a fluid intended to cool the electrical equipment 1. The first wall 111 comprises a groove 112 which comes face to face with a groove 122 of the second wall 120 to form the circuit. cooling 200.
    In particular, the first groove 112 and the second groove 122 come face to face to form a channel 210 of the cooling circuit in which the cooling fluid will flow. Thus, the diameter of the cooling channel is distributed between the two walls. This makes it possible to distribute between the two walls the stresses on the wall thickness which are due to the formation of the cooling circuit 200 and to balance between them the housing 117 defined by the first housing 110 and the housing 127 defined by the second housing 120.
    In particular, the first 111 or second 121 walls may further comprise through openings at the cooling circuit 200. These openings are obstructed by a plate attached to the wall 111, 121 after mounting the first box 110 and the second limp 120 on each other. Such a plate is for example constituted by a portion of an electrical component mounted on the wall 111, 121.
    Alternatively, the cooling circuit is integrally formed by the first 112 and the second groove 122. In other words, the cooling channels 210 are formed solely by the grooves 112, 122. In particular, the first 111 and second 121 walls are each parts in one piece.
    In particular, the first wall 111 and the second wall 121 come against each other at respective substantially planar surfaces 113, 123, so-called bearing surfaces. The bearing surface 113 of the first wall 111 comprises the edges of the first groove 112; and the bearing surface 123 of the second wall 121 comprises the edges of the second groove 122. By edge of the first 112 or the second groove 122 is meant the boundary between the groove 112, 122 and the surface from which the 112,122 throat is digging. The surface from which the first groove 112 is hollow corresponds in particular to the bearing surface 113 of the first wall 111; and the surface from which the second groove 122 is hollow corresponds in particular to the bearing surface 123 of the second wall 121. In particular, the edges of the first 112 or second 122 grooves are integrally included in their bearing surface 113, 123 respective.
    By providing flat bearing surfaces between the first 111 and the second wall 121, it facilitates the implementation of the sealing of the cooling circuit 200. Indeed, the portions of the first wall 111 and the second wall 121 which come against each other to form the cooling circuit 200 are preferably machined to remove surface irregularities that could create coolant leakage gaps out of the cooling circuit 200. Providing contact surfaces 113, 123 planes facilitates the machining of these bearing surfaces 113, 123.
    In addition, it is preferable that only the bearing surfaces 113, 123 of the walls 111, 121 are machined and not the zones which are in contact with the cooling fluid such as the grooves 112, 122. In fact, by machining the grooves 112, 122 there is a risk of exposing porosities in the material of the first 111 or second wall 121. During the circulation of the cooling fluid, it could infiltrate into the wall 111, 121 by the intermediate these porosities to leak through the first wall 111 or the second 121 wall. By providing that the cooling circuit 200 is formed by the first groove 112 in the first wall and the second groove 122 in the second wall 121 is facilitated machining. In a case of the prior art, where the first wall is flat and does not include a groove, it is necessary to perform a selective machining which only machines the parts of the first wall which are intended to come into contact with the second wall avoiding portions of the first wall which are intended to be in contact with the cooling fluid, since defining a portion of the cooling channel. The machining is done with a polishing head whose diameter is less than or equal to the distance between two channels of passage of the cooling fluid. For the set 100 forming the housing of the electrical equipment 1 illustrated, the machining tool may have a polishing head of diameter greater than the distance between two cooling fluid passage channels because the polishing head will be in contact only with the bearing surface 113. It can therefore machine more surface with the polishing head, which reduces the machining time. It also avoids the implementation of a complex path of the polishing head for selective machining.
    In addition, the first wall 111 may be devoid of protrusions extending beyond its bearing surface 113 and the second wall 121 may be free of protrusions extending beyond its bearing surface 123 , at least in the zones 111a, 121a of the walls 111, 121 which form the cooling circuit 200. This further facilitates the passage of a single machining tool on the face of the first wall 111 and that of the second wall 121 which will come to form the cooling circuit 200.
    The depth of the first groove 112 may be greater than that of the second groove 122. In particular, the first groove 112 has a depth of between 5 and 20 mm, in particular equal to 10 mm; and the second groove 122 has a depth of between 0.5 and 1 mm, in particular equal to 1 mm. This difference in depth between the first groove 112 and the second groove 122 limits the thickness of the second wall 122 to obtain more space in the second housing 127.
    The first wall 111 may comprise at least one through hole 114 and the second wall 121 may comprise at least one through hole 124 whose edges come into contact with one another to form a passage between the face of the first wall 111 which is opposed to the face carrying the first groove 112 and the face of the second wall 121 which is opposite the face bearing the second groove 122. In particular, these through holes 114, 124 form a passage between a first housing 117 defined by the first housing 110 and a second housing 127 defined by the second housing 120, described below. These through holes 114, 124 are in particular formed outside the zones 111a, 121a of the first 111 and second 121 walls which form the cooling circuit 200.
    A seal may be positioned between the first wall 111 and the second wall 121. An example of a seal 130 is illustrated in FIG. 12. In particular, the seal 130 provides a seal around the zones 111a, 121a. first 111 and second 121 walls which form the cooling circuit 200. For this purpose, the seal 130 comes in particular between the bearing surfaces 113, 123 of the first wall 111 and the second wall 121. sealing member 130 may be devoid of material in a portion which is in the cooling circuit 200 when formed except for strips of material 134, 135, 136. These strips of material 134, 135, 136 improve the rigidity of the seal 130 so as to facilitate the handling and placement of the seal 130. These strips of material 134, 135, 136 may have widths just sufficient to obtain a rigidity and define openings 131, 132, 133. The seal 130 seals along a closed line around the cooling circuit 200, especially around the areas 111a, 121a of the walls 111, 121 which form the circuit The seal 130 may also seal around the passageways formed in the first wall 111 and the second wall 121. The seal 130 then includes holes 137 whose edges seal around it. said passages. The seal 130 may also include holes 139 which allow the passage of respective fasteners for fixing the first wall 111 on the second wall 121.
    The cooling circuit 200 may include an input port 201 and an output port 202 through which the coolant enters and exits the cooling circuit 200. The input 201 and output ports 202 are included in the second housing 120, in particular in a side wall 126 of the second housing 120 described hereinafter. In particular, the input / output ports 201, 202 are tubular openings in the side wall 116. These input / output ports 201, 202 are extended by tubes 203, 204 which communicate with the second groove 122 of the second wall 121. to route or extract the cooling fluid. The input / output ports 201, 202 could have been similarly understood in the first housing 110. By providing the input / output ports 201, 202 in one of the two housings 110, 120, the implementation of FIG. the seal at the input / output ports 201, 202. Alternatively, the input / output ports 201, 202 could have included a first portion from the first housing 110 and a second portion from the second housing 120, the two parts coming against each other when the cooling circuit 200 is formed. Nozzles 205, 206 may be inserted into the input / output ports 201, 202 to adapt them to a cooling fluid supply circuit.
    Each housing 110, 120 may include respective side walls 116, 126 that extend transversely from the periphery of the first or second wall 121 to define a respective first housing 117 and second housing 127. In particular, when the first 110 and second 120 housings are mounted on each other so as to form the cooling circuit 200, the side walls 116 of the first housing 110 extend in a direction opposite to the second housing 120 and the side walls 126 of the second housing 120 extend in a direction opposite to the first housing 110. Each housing 117, 127 can be closed by a respective cover 118, 128 which comes against the distal ends of said side walls 116 126. Thus, the first wall 111 forms a bottom of the first housing 110 and the second wall 121 forms a bottom of the second housing 120.
    The first wall 111 may receive one or more first components 300, 310 housed in the first housing 117, for example as illustrated in FIG. 7. The first housing 117 may comprise an electronic power module 300 which comprises components intended to power the machine. electrical and / or an insulated metal substrate (SMI) card 310 which carries components for the voltage conversion between the first and second electrical network of the vehicle.
