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.

Power unit, in particular for an aircraft

A wound element made up of a plurality of superposed layers of turns wound on a core, including a sheet of a material that is thermally conductive at least in its plane, which sheet is interposed between two of the superposed layers of turns and has an end projecting from these layers and including at least one temperature probe for delivering temperature information about the wound element.

Coiled elements comprising a temperature measuring device

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.
