Abstract

L'invention se rapporte à un dispositif de refroidissement pour un transformateur monté sur un véhicule électrique, dont les positions d'installation possibles ne se limitent pas à l'intérieur du véhicule électrique et qui est ininflammable et sûr. Ce dispositif de refroidissement comprend un refroidisseur (23) d'un milieu réfrigérant (25) pour refroidir le transformateur (21), et une soufflante de mise en circulation (22) disposée à l'intérieur d'un conduit (24) connecté entre le transformateur (21) et le refroidisseur (23), pour mettre en circulation le milieu réfrigérant entre le transformateur et le refroidisseur. Le milieu réfrigérant (25) est constitué par un gaz SF6, le refroidisseur est disposé sur la paroi latérale, la paroi supérieure ou la paroi terminale avant ou arrière de la carrosserie du véhicule électrique (1) et le refroidisseur est refroidi par la soufflante ou par de l'air soufflé. Ainsi, on rend le dispositif de refroidissement ininflammable, on agrandit les espaces d'installation pour les autres appareils électriques et on augmente la liberté de conception de l'installation du refroidisseur. On peut réduire le bruit en disposant la soufflante de mise en circulation de gaz à l'intérieur de la cuve du transformateur, et on peut éliminer l'opération de scellage sur place du gaz constituant le milieu réfrigérant, en disposant une partie de connexion ouvrante au niveau d'une partie intermédiaire du conduit du milieu réfrigérant.
