Abstract
The electronic component with heat transfer by boiling and condensation comprises heat exchange surfaces immersed in a heat conducting fluid constituted by the free ends of nanowires of a thermoelectric converter. An electrically insulating coating material with a low thermal conduction partially covers the nanowires above the heat conducting fluid. Each nanowire forms a thermocouple composed of two coaxial branches made from materials of different natures separated by a layer of electrically insulating material and electrically connected individually to the free end of the nanowire.
Claims6
An electronic component comprising a thermoelectric converter and a heat conducting fluid, the thermoelectric converter comprising a base substrate, and a plurality of nanowires formed on the base substrate, each nanowire comprising:
- a free end being immersed in the heat conducting fluid, a core, an electrically insulating material surrounding the core, and an envelope of a different material than the core surrounding the electrically insulating material, the envelope forming a thermocouple with the core and being electrically connected to the core at the free end of each nanowire;
- the cores of two adjacent nanowires are connected by a layer of doped semi-conducting material of a first type, constituting a base substantially perpendicular to the nanowires;
- the layer of insulating material covers the base between two adjacent nanowires, the envelopes of two adjacent nanowires being connected, above the layer of insulating material, by a layer of doped semi-conducting material of a second type.
A method for producing an electronic component with heat transfer by boiling and condensation, comprising:
- forming a thermoelectric converter comprising a plurality of nanowires on a base substrate, each nanowire forming a thermocouple comprised of a core, an electrically insulating material surrounding the core, and an envelope of a different material than the core surrounding the electrically insulating material, the envelope forming a thermocouple with the core and being electrically connected to the core at the free end of each nanowire;
- partially impregnating the nanowires by an electrically insulating coating material with a low thermal conduction;
- and immersing the free ends of the nanowires in a heat conducting fluid of a heat pipe.
