Abstract: A power assembly that has at least two power modules that each have at least one component to be cooled, for example, an electronic chip mounted on a base from which cooling elements extend. Each power module also has a hollow body with a channel for flow of a coolant fluid Each power module is mounted on each respective body so that the cooling elements extend at least partially into said channel through an opening of the body. At least one deflector is mounted in the channel between the cooling elements of the two modules so as to force the coolant fluid to flow in the zone of the channel comprising the cooling elements.

Abstract: An electronic device with cooling of a heat dissipation source, by a liquid metals spreader, the device including at least one heat dissipation source, at least one spreader through which at least one liquid metal circulation channel passes forming a loop routed below a heat dissipation source, at least one heat sink, and at least one electromagnetic pump moving the liquid metal in the at least one channel such that the liquid metal absorbs heat dissipated by a heat dissipation source and transports the absorbed heat to be evacuated by the heat sink. Each spreader includes at least two plates made of an electrical insulating material located on each side of at least one bar made of deformable material.

Abstract: A method for cooling an electricity generator (50) for delivering electricity to a first rotor (60), the first rotor being suitable for being rotated relative to a stationary structure, the method being characterized in that the electricity generator is placed in a chamber (62) arranged inside the first rotor, and in that it comprises the following steps: a) transferring heat produced by the generator to a cooling fluid, thereby vaporizing the fluid in an evaporator (64); b) transporting the vaporized fluid to a condenser; and c) condensing the fluid in the condenser, the heat delivered by the fluid being transmitted to the air surrounding the condenser.
