Abstract

L'invention porte sur un système de refroidissement combinant un circuit de refroidissement à boucle de pompage à réfrigérant diphasique et un circuit de boucle de compression de vapeur dans un boîtier de refroidissement de circuits électroniques destinés à être utilisés dans des applications à température ambiante élevée. Des applications spécifiques peuvent comprendre, mais sans s'y limiter, des convertisseurs électroniques de puissance, des commandes par onduleur et des véhicules électriques hybrides. Dans des applications à des véhicules électriques hybrides, on utilise le système principal de refroidissement à réfrigérant diphasique pompé pour fournir un refroidissement à haute température à la commande par onduleur. On utilise le système secondaire à compression de vapeur pour fournir un refroidissement à basse température au module de batterie (à savoir, par exemple, des cellules Li-ion) ou un refroidissement de cabine de passagers, de façon à éliminer ainsi la nécessité d'une solution de refroidissement spéciale pour le module de batterie, nécessitant un refroidissement à plus basse température.
