Abstract
Ensemble de refroidissement de moteur électrique hermétiquement fermé. L'ensemble comportant un moteur d'entraînement électrique utilise une partie du liquide sous-refroidi qui passerait normalement du condensateur, par l'intermédiaire d'un dispositif d'expansion, à l'évaporateur pour refroidir le moteur. Le canal de refroidissement de rotor qui s'étend longitudinalement dans la partie extérieure du rotor a sa surface la plus à l'extérieur qui a la forme d'un arc ayant le même centre que le rotor. Cela permet une répartition égale du liquide de refroidissement sous l'influence des forces centrifuges. Le stator comprend un canal entre sa surface extérieure et la partie de refroidissement longitudinale du stator. Le canal s'étendant vers l'intérieur 36 comprend un orifice 51, 55 qui est suffisamment grand pour éviter des problèmes de contamination, mais constitue un bon étranglement et assure ainsi un bon transfert de chaleur. Application aux dispositifs de réfrigération.
