  • Electric drive unit with rotor heat sink formed of heat sink elements
    Patent number: 12283875
    Abstract: An electric drive unit that includes an electric motor having motor output shaft and a heat sink that is received therein. The heat sink is comprises of a plurality of discrete heat sink elements that are stacked together and inserted into the motor output shaft. The heat sink elements have central hubs that cooperate to form a coolant supply passage that extends centrally through the heat sink. Each of the heat sink elements defines a plurality of discrete coolant return passages that are relatively shorter in length than the central hubs so that a void annular space is formed between the coolant return passages of adjacent heat sink elements.
