Abstract: In some examples, a system uses ambient air from outside a controlled airflow environment to cool equipment within the controlled airflow environment. The system can include ductwork that seals the ambient air from air outside of the ductwork within the controlled airflow environment. The system can further include a passive heat exchanger connected to the equipment and extending into an interior of the ductwork to allow heat exchange between the equipment and the ambient air. The system can further include a fan to flow the ambient air through the ductwork, the fan being connectable to the equipment to allow the equipment to control the operation of the fan.
