  • Publication number: 20240349458
    Abstract: Aspects of the disclosure include a heat sink having variable pins. An exemplary heat sink can include a plurality of pins extending from a surface of the heat sink. The plurality of pins can include a first pin and a second pin. The first pin can include a first set of pin features and the second pin can include a second set of pin features. The first set of pin features and the second set of pin features differ in at least one pin feature. The heat sink can be configured to remove heat from a component of a vehicle. The component can include an electric motor, a battery pack, and an inverter electrically coupled to the electric motor.
