Abstract

L'invention concerne un générateur d'énergie électrique par refroidissement, qui absorbe l'énergie thermique provenant de l'environnement par un collecteur thermique de refroidissement (4) et l'accumule dans un noyau (1) cumulant l'énergie thermique au moyen d'un dispositif de pompe à chaleur (8), qui est démarré initialement par une batterie d'accumulateurs (10). La différence de température entre le noyau (1) cumulant l'énergie thermique et le collecteur thermique de refroidissement (4) produit une tension électrique en courant continu dans un ensemble de thermocouples (3), par l'effet Seebeck. L'énergie électrique excédentaire provenant de l'ensemble de thermocouples (3) alimente en outre le dispositif interne de pompe à chaleur (8), de sorte que l'énergie thermique d'absorption provenant de l'environnement est continue. L'excédent d'énergie thermique absorbée précédemment est utilisé par l'ensemble de thermocouples (3), sous forme d'énergie électrique, pour recharger une batterie d'accumulateurs (10) et pour alimenter un client (14) en énergie électrique. Ce générateur d'énergie électrique par refroidissement ne requiert aucun chauffage de matière et rend superflue la consommation de divers types de combustible en vue de la production de grandes quantités d'énergie électrique.
