    Thanks to the invention, it is possible to have a better cooled electrical equipment. Indeed the conductors, for example one positive and the other negative, being in the same plane, are cooled at the same time and uniformly.
    Preferably, the heat exchange portions of the conductors are in direct or indirect thermal contact with the cooling device, in particular via an electrical insulating thermal conductor placed on the cooling device.
    If desired, the heat exchange portions of the two conductors have substantially identical areas.
    For example, at least one of the conductors is copper or aluminum. For example, at least one of the drivers is a busbar.
    The heat exchange portions of the two conductors have, for example, substantially identical thicknesses.
    In particular, one of the heat exchange portions is connected to a positive terminal of the electrical power component and the other of the heat exchange portions is connected to a negative terminal of the other electrical power component. At least one of the electrical conductors is in particular connected to terminals of the same polarity of the two electrical power components. At least one of the electrical conductors is in particular connected to positive terminals of the two electrical power components.
    Advantageously, at least one of the electrical conductors, connected with one of the electrical power components, comprises, in addition to the heat exchange portion, an electrical contact portion with the other electrical power components, this contact portion. in particular being remote from the cooling device.
    In particular, the contact portion of one of the conductors is substantially parallel to the heat exchange portion of the other of the electrical conductors.
    For example, the contact portion of one of the conductors is substantially flat.
    If necessary, the contact portion of one of the conductors is on one side of the electrical component and the heat exchange portion of the other of the conductors is on an opposite side of this electrical component.
    In particular, the contact portions, preferably remote from the cooling device, are substantially coplanar.
    If desired, at least one of the conductors comprises an arm connecting the heat exchange portion to the contact portion, this arm preferably being substantially perpendicular to the heat exchange portion.
    Preferably, the arm is disposed between the two electrical power components, this particular arm along one side of one of the electrical power components.
    Preferably the two conductors each comprise an arm, the arms of these two conductors being substantially coplanar. This allows a better compactness.
    In particular, the two conductors are electrically insulated from one another, for example by an air knife, an electrical insulator including a lining, a paper.
    For example, the heat exchange portions have at least one straight edge, the right edges of the portions being aligned.
    Where appropriate the heat exchange portions have a substantially rectangular shape. At least one of the conductors, preferably the two conductors, is in particular connected to a power module via connection tabs, for example to convert electrical energy.
    The connecting tabs of the two conductors are arranged alternately between them for example.
    For example, the conductors are made by cutting and folding a plate. The conductors are in particular based on aluminum or copper. The drivers are still called English Busbaren.
    The legs each have an elbow if desired.
    For example the legs are connected to a common rim of the driver.
    If desired, at least one of the electrical power components comprises at least one electrical energy storage unit, in particular a capacitor, in particular a plurality of units, in particular capacitors, for example three capacitors. For example, each component comprises a group of three capacitors.
    The cooling device comprises in particular a heat exchange wall against which the heat exchange portions of the conductors are placed, this wall preferably being substantially flat.
    Preferably, the cooling device comprises a circulation channel for a cooling fluid, for example water or glycol. The heat exchange wall is in particular in contact with the cooling channel.
    The heat exchange wall is made of aluminum for example. The equipment includes a power module in thermal contact with the cooling device.
    Preferably, the power module comprises a plurality of electrical connection tabs arranged for the electrical connection of the power module with the electrical power components.
    Advantageously, the conductors are arranged so that they are cooled by the cooling device before the electrical output of the power module.
    For example, the equipment is arranged in power module, for example inverter, in particular DC / AC. The inverter is for example designed to operate at a power greater than 50 kW, in particular 100 kW, operating in particular with an electric power of 140 kW.

    The arm 20 is disposed between the two electrical power components 2 and 3, and this arm 20 runs, without touching, one side of the electrical power components.
    The arms 20 of these two conductors are substantially coplanar. This allows a better compactness.
    The two conductors 4 and 5 are electrically insulated from each other.
    As can be seen in FIG. 3, the two conductors 4 and 5 are connected to a power module 30 via connection tabs 31.
