<p>A nuclear generator 10 comprises: a heat source formed of a radioisotopic source 11; a heat sink; a thermal energy converter 12 arranged between said heat source and said heat sink so that a heat flux passes through the thermal energy converter; a vessel 16 in which are laid out the thermal energy converter 12 and the heat source; said vessel 16 being in contact with the heat sink; the generator being characterised in that the heat sink comprises at least one plate cooling fin 21 having an internal structure forming at least one diphasic network (see figure 2) enabling the evaporation, the circulation and the condensation of a working fluid. The generator is preferably used in satellites.</p> |
