Airborne cooling system

An apparatus comprising:

• an aircraft having a power plant operable to provide thrust and propel the aircraft at a flight speed, the aircraft including a relatively high temperature device that benefits from a cooling process and a refrigeration system capable of providing a cooling to the relatively high temperature device, the refrigeration system having:
• a heat providing component in communication with a heat absorbing component via a working fluid that flows from the heat absorbing component to the heat providing component, the heat providing component disposed in thermal communication with a duct having a flow of heat exchange fluid, the heat absorbing component in thermal communication with the relatively high temperature device;
• a delivery discharge operable to emit a phase transition medium into the duct with the heat exchange fluid;
• and
• wherein the heat providing component exchanges heat with the heat exchange fluid and the phase transition medium.

A method comprising:

• operating an aircraft at a flight speed, the aircraft having an external store that includes a heat rejecting component of a heat exchange system;
• receiving a flow of air into the external store though an inlet;
• conveying a cooling medium into the flow of air;
• changing phase of the cooling medium;
• and
• extracting heat from the heat rejecting component disposed wherein the extracting occurs downstream of the inlet.
