Abstract

L’invention concerne un dispositif de motorisation électrique (1) comprenant un moteur électrique (30) comprenant un palier arrière (50) et un palier avant (32), un système électronique (20), et un dissipateur thermique (40) étant destiné à refroidir le système électronique (20). Le dissipateur thermique (40) comprend une plaque d’isolation électrique (42) configurée pour permettre un échange thermique entre un liquide de refroidissement et le système électronique (20), et un couvercle d’isolation thermique le couvercle d’isolation thermique (44) formant avec le palier avant (32) au moins un canal interne (38) de circulation de liquide à l’intérieur duquel circule le liquide de refroidissement, la plaque d’isolation électrique (42) et le couvercle d’isolation thermique (44) définissant entre eux une cavité (48) configurée pour permettre le passage du liquide de refroidissement, ladite cavité (48) étant en connexion fluidique avec le canal interne (38) par l’intermédiaire du couvercle d’isolation thermique (44). Figure 4The invention relates to an electric motorization device (1) comprising an electric motor (30) comprising a rear bearing (50) and a front bearing (32), an electronic system (20), and a heat sink (40) being intended cooling the electronic system (20). The heat sink (40) includes an electrical insulation plate (42) configured to allow heat exchange between a cooling liquid and the electronic system (20), and a thermal insulation cover the thermal insulation cover (44 ) forming with the front bearing (32) at least one internal liquid circulation channel (38) inside which circulates the cooling liquid, the electrical insulation plate (42) and the thermal insulation cover (44 ) defining between them a cavity (48) configured to allow the passage of the cooling liquid, said cavity (48) being in fluid connection with the internal channel (38) via the thermal insulation cover (44).
