Abstract
A system for cooling a motor operating within an aircraft system includes an enclosure receiving ram air from a first ram air duct and discharging ram air to a second ram air duct to form a cooling path. The second ram air duct is discrete and independent from the second ram air duct. The system can discharge ram air between a heat exchanger and a fan within the second ram air duct that define a reduced or negative pressure region within the second ram air duct.
