Title
(EN) COOLING STRUCTURE FOR VEHICULAR ELECTRIC MOTOR
(FR) STRUCTURE DE REFROIDISSEMENT POUR MOTEUR ÉLECTRIQUE DE VÉHICULE
(JA) 車両用電動機の冷却構造
Abstract
(EN)
In this cooling structure for a vehicular electric motor, the following are arranged around a vehicular electric motor (30): a compressor (50) that compresses air; a vortex tube (60) that forms a straight cylinder by which compressed air supplied from the compressor (50) is separated into warm air and cold air, and said warm air and said cold air are discharged individually; and a cold air duct (70) that guides the cold air discharged from the vortex tube (60) to the vehicular electric motor (30). As a result, it is possible to efficiently cool an electric motor and further improve the power consumption rate of the electric motor.
(FR)
Dans cette structure de refroidissement pour un moteur électrique de véhicule, les éléments suivants sont disposés autour d'un moteur électrique de véhicule (30) : un compresseur (50) qui comprime de l'air ; un tube tourbillon (60) formant un cylindre droit par lequel de l'air comprimé fourni par le compresseur (50) est séparé en air chaud et en air froid et ledit air chaud ainsi que ledit air froid sont évacués individuellement ; et un conduit d'air froid (70) qui guide l'air froid évacué du tube tourbillon (60) vers le moteur électrique de véhicule (30). Par conséquent, il est possible de refroidir efficacement un moteur électrique et d'améliorer encore le taux de consommation d'énergie du moteur électrique.
