Abstract:
A ram fan device includes a motor disposed in a housing that defines a motor cavity with a fan operatively connected to be driven by the motor and an outlet in fluid communication with the motor cavity. The housing includes a cooling inlet therethrough downstream of the fan and upstream of the motor, the cooling inlet being in fluid communication with the outlet through the motor cavity such that airflow can pass through the cooling inlet through the motor cavity and out the outlet.
