Title (EN) LIQUID COOLING ARRANGEMENT FOR ELECTRIC MACHINES
(FR) AGENCEMENT DE REFROIDISSEMENT LIQUIDE POUR MACHINES ÉLECTRIQUES
Abstract:
(EN) A liquid cooling arrangement for electric machines uses a continuous cooling tube associated with a heat storing element. The cooling tube has a serpentine configuration and the heat storing element includes longitudinal slots starting from both longitudinal ends of the heat storing element. Accordingly, it is possible to slightly deform the heat storing element to properly position it into the internal stator of an electric machine. An internal biasing assembly may be used to force the external surface of the heat storing element to the internal surface of the stator.
(FR) L'invention porte sur un agencement de refroidissement liquide pour machines électriques qui utilise un tube de refroidissement continu associé à un élément de stockage de chaleur. Le tube de refroidissement présente une configuration en serpentin et l'élément de stockage de chaleur comprend des fentes longitudinales partant des deux extrémités longitudinales de l'élément de stockage de chaleur. En conséquence, il est possible de légèrement déformer l'élément de stockage de chaleur pour le positionner correctement dans le stator interne d'une machine électrique. Un ensemble de sollicitation interne peut être utilisé pour pousser la surface externe de l'élément de stockage de chaleur vers la surface interne du stator.
