  • Power electronic module cooling system and method
    Patent number: 9192079
    Abstract: An improved cooling mechanism for a power electronics device is provided. More specifically, a cooling mechanism is provided that includes an air passageway configured to allow cooling air to bypass a portion of a heatsink adjacent to the rectifier circuitry and direct cooling air into an area of the heatsink that is nearer to the inverter circuitry. Another embodiment employs an air passageway with an air directing structure configured to provide an air flow that impinges on a lateral surface of the heatsink. In another embodiment, the air directing structure is chosen to provide a turbulent air flow in the heat dissipating structure within the vicinity of the inverter circuitry.
