Abstract

Système de refroidissement et unité d’entraȋnement et véhicule électriques le comportant Un système de refroidissement (1) notamment dévolu à un moteur électrique d’entraînement (M), dans un véhicule à entraînement électrique, comporte un moyen (4) de conduction thermique et un manchon de refroidissement (2) qui présente un axe longitudinal (3) et entoure ledit moyen (4) le long dudit axe longitudinal (3). Un canal de refroidissement (5) acheminant un fluide de refroidissement (6) est formé entre ledit manchon (2) et ledit moyen (4), lequel moyen reçoit une première source de chaleur (7) notamment matérialisée par un stator dudit moteur (M). Ledit moyen (4) de conduction thermique est conçu pour entrer en contact thermoconducteur avec une seconde source de chaleur (8) notamment matérialisée par une électronique de puissance qui est affectée audit moteur (M) et qui occupe, le long de l’axe longitudinal (3), un emplacement axial par rapport à la première source de chaleur (7). Figure à publier avec l’abrégé : Fig. 1
