Abstract
A hybrid cooling system of an electric machine is contemplated. The hybrid cooling system includes a propeller assembly comprising a propeller, a housing comprising a stator and a rotor coupled to the propeller, and one or more capacitors, a gate drive electronics board, a cold plate, a substrate, power electronics coupled to substrate and the cold plate, a pump for pumping liquid coolant, and a heat exchanger. The liquid coolant from the pump contacts the gate drive electronics board, the cold plate, the substrate, and the power electronics for cooling the gate drive electronics board, the cold plate, the substrate, and the power electronics, and the propeller is configured to generate air that cools the stator and the rotor.
