Abstract
An electric motorization device including an electric motor, an electronic system comprising power electronic elements, and a heat sink that is intended to cool the electronic system. The heat sink comprises a first shell configured to allow heat exchange between a coolant fluid and the electronic system, and a second shell configured to prevent heat exchange between the coolant fluid and the electric motor. The first shell and the second shell together define a cavity configured to allow the passage of the coolant fluid. The first shell and the second shell are each made of a material configured to ensure electrical insulation, in particular between the electronic system, the coolant fluid and the electric motor.
