Abstract

L'invention porte sur un dispositif de refroidissement pour un module convertisseur électronique de puissance. Le but de l'invention est de maintenir à un niveau le plus faible possible l'écart de température sur l'échangeur de chaleur situé dans un dispositif de refroidissement destiné à un module convertisseur électronique de puissance. A cet effet, le dispositif de refroidissement est muni d'un canal à liquide de refroidissement dans lequel circule un réfrigérant liquide et qui est raccordé à un circuit de refroidissement, d'un échangeur de chaleur, qui est monté dans le circuit de refroidissement et auquel un composant de puissance est accouplé de manière à conduire la chaleur, et d'un refroidisseur destiné à refroidir le réfrigérant liquide et monté dans le circuit de refroidissement, plusieurs conduites étant montées en parallèle dans l'échangeur de chaleur de sorte que l'écart de température sur ledit échangeur de chaleur ne dépasse pas une grandeur prédéfinie.
