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.
