Abstract

L'invention concerne un système (SYS) d’électronique de puissance pour véhicule électrique ou hybride, comportant : - un carter métallique (CA) comportant un premier logement (LOG1) enfermant au moins un composant d’électronique de puissance (IND), une paroi inférieure (PAI) dudit premier logement (LOG1) étant refroidie par un liquide de refroidissement (WAT) à l’extérieur dudit premier logement (LOG1), ledit liquide de refroidissement (WAT) circulant dans un circuit de refroidissement (CR) s’étendant de façon externe audit carter métallique (CA), - un deuxième logement (LOG2), en contact thermique avec ladite paroi inférieure (PAI) et dans lequel circule ledit liquide de refroidissement (WAT), ledit système (SYS) étant caractérisé en ce que ledit au moins un composant d’électronique de puissance (IND) est immergé dans un liquide diélectrique caloporteur (OIL) confiné dans ledit premier logement (LOG1). Figure pour l’abrégé : Figure 1The invention relates to a power electronics system (SYS) for an electric or hybrid vehicle, comprising: - a metal casing (CA) comprising a first housing (LOG1) enclosing at least one power electronics component (IND), a lower wall (PAI) of said first housing (LOG1) being cooled by a cooling liquid (WAT) outside of said first housing (LOG1), said cooling liquid (WAT) circulating in a cooling circuit (CR) s 'extending externally to said metal casing (CA), - a second housing (LOG2), in thermal contact with said lower wall (PAI) and in which said cooling liquid (WAT) circulates, said system (SYS) being characterized by that said at least one power electronic component (IND) is immersed in a dielectric coolant (OIL) confined in said first housing (LOG1).
