  • Patent number: 11864358
    Abstract: An apparatus, such as a power routing apparatus, includes an enclosure having first and second compartments having respective first and second opposing walls. A cooling structure is disposed between the first and second compartments and has a coolant passage defined therein configured to support a coolant flow in a direction parallel to the first and second opposing walls. First and second semiconductor switches (e.g., static switches) are disposed on the first and second walls on opposite sides of the coolant passage and are configured to be cooled by the coolant flow.
    Type: Grant

  • Patent number: 10842048
    Abstract: An apparatus, such as a transformer cabinet, includes a housing (e.g., a sheet metal enclosure) having electrical equipment (e.g., a transformer) disposed therein. A duct in the housing is configured to direct a first airflow in the housing to create a vortex that entrains a second airflow that passes over the electrical equipment. The housing may have a first opening configured to provide the first airflow and a second opening configured to provide the second airflow. The first opening may be in a side wall of the housing and the second opening may be proximate a bottom of the housing. The side wall may include a first side wall and the duct may be configured to direct the first airflow upwards and towards a second side wall of the housing.
