Abstract

L'invention concerne l'utilisation de modules semi-conducteurs pour le préchauffage ou le chauffage de moteurs à combustion interne, en particulier par préchauffage ou chauffage des liquides se trouvant dans ces moteurs. Le module semi-conducteur utilisé selon l'invention est placé de telle sorte qu'il est parcouru par le fluide associé, par exemple l'huile moteur ou le carburant à préchauffer, et l'énergie électrique est apportée aux thermocouples formant le module semi-conducteur, produisant ainsi de la chaleur qui est fournie au fluide parcourant le module semi-conducteur.
