摘要
A streamlined electronic-component-containing pod is mounted on the exterior of a military aircraft in subjection to the airflow past the aircraft during flight. An evaporator in the pod is close coupled thermally to the electronic components for cooling. The outer skin of the pod acts as a condenser for return of liquid refrigerant to the evaporator during normal flight operations. During short-term high-speed dash operation the outer skin of the pod becomes too hot for condensing refrigerant vapor, which then becomes condensed by a heat sink. At this time the refrigerant at the outer skin remaining in the vapor phase acts as thermal insulation.
