    Method of manufacturing a porous heat sink for electronic devices using computational computer aided design techniques based on a method based on voronoi diagrams. The obtained porous heat sink is characterized by having variable and interconnected macroporosity. Said macroporosity is established from the definition of the trabecular thickness of non-constant section (tb.th), of the trabecular separation (tb.sp), of the number of voronoi nucleation points and of the volume of the area to be filled. Said porous heat sink is manufactured from additive techniques by three-dimensional printing (3d) with conductive materials. This invention is applicable in the field dedicated to the manufacture of dissipators or heat exchangers responsible for the evacuation of heat from an element with high temperature to a medium with lower temperature with or without forced circulation of air. Its high specific surface area and the possibility to shape it by adapting it to a predefined volume allows optimizing the evacuation of heat in small spaces.
