Abstract:
(EN) The invention relates to a thermally conductive, fibre-reinforced plastic for electric motor housings, in particular a low-weight housing, of light-weight construction. According to the invention, a new housing structure for electric motors is provided, said housing structure having material modifications by fibre-reinforced plastic such as carbon-fibre-reinforced plastic for increasing the thermal conductivity in the thickness direction by introducing materials of higher thermal conductivity, such as metal pins, in combination with the housing cooling via a cooling jacket through which fluid flows. This represents novel technology for producing a heat-dissipating housing using fibre composite technology.
(FR) 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.
(DE) Die Erfindung betrifft einen wärmeleitfähigen, faserverstärkten Kunststoff für Elektromotorengehäuse, insbesondere einen mit geringem Gewicht, also in Leichtbauweise. Durch die Erfindung wird erstmals ein Gehäuseaufbau für Elektromotoren mit Materialmodifikationen von faserverstärkten Kunststoffen wie carbonfaserverstärktem Kunststoff zur Steigerung der Wärmeleitfähigkeit in Dickenrichtung durch die Einbringung von höher wärmeleitfähigen Materialien, beispielsweise von Metallstiften, in Kombination mit der Gehäusekühlung über einen flüssigkeitsdurchströmten Kühlmantel. Dadurch wird eine neuartige Technologie für eine wärmeableitende Gehäuserealisierung in Faserverbundtechnik dargestellt.
