Abstract

L'invention porte sur un dispositif de conversion d'énergie. Les structures de refroidissement classiques avaient les inconvénients de présenter seulement un refroidissement par contact direct avec une surface latérale d'une boîte en métal, sans prendre en considération la transmission de chaleur dans de nombreuses directions, ni le fait qu'on demande un refroidissement plus efficace. La chaleur dégagée par un élément magnétique est efficacement dispersée dans une boîte par le fait qu'un transformateur et un élément inducteur sont positionnés dans l'espace de logement formé par une nervure plantée à l'intérieur de la boîte, et que le transformateur, l'élément inducteur et la nervure sont remplis d'une résine qui possède des propriétés de radiation et d'isolation.
