Abstract

L'invention concerne une matière plastique renforcée par fibres à conductivité thermique pour des carters de moteurs électriques, en particulier de poids réduit, c.-à-d. de construction légère. L'invention permet pour la première fois de parvenir à une structure de carter pour moteurs électriques, présentant des modifications en termes de matériaux, intervenant au niveau de matières plastiques renforcées par fibres comme des matières plastiques renforcées par fibres de carbone pour augmenter la conductivité thermique dans le sens de l'épaisseur par introduction de matériaux à haute conductivité thermique, en particulier des tiges métalliques, en association avec le refroidissement du carter par le biais d'une chemise de refroidissement parcourue par un fluide. Il est ainsi possible de présenter une technologie d'un genre nouveau pour une conception de carter à dissipation de la chaleur relevant de la technique des matériaux renforcés par fibres.
