Patent ID: 7561424

Claim:
A method for cooling electronic components of a control unit in an unmanned flying vehicle, the method comprising: providing a cooling device in the unmanned flying vehicle, the cooling device comprising a temperature measurer configured to measure a temperature of the electronic components, a sprayer configured to spray liquid cooling medium, a container containing the liquid cooling medium and an enclosure containing the electronic components, the temperature measurer, the sprayer and the container, the enclosure comprising a closed box in said flying vehicle, wherein said container and said electronic components are integrated into the closed box, measuring a temperature of the electronic components with the temperature measurer, spraying a liquid cooling medium from the container directly upon said electronic components with the sprayer when the temperature of the electronic components exceeds a predetermined level, wherein the liquid cooling medium has a boiling temperature close to said predetermined temperature level, wherein the liquid cooling medium is sprayed directly upon the electronic components for removing heat energy from the electronic components by evaporation of said cooling medium, connecting the enclosure to the unmanned flying vehicle with connecting members, wherein the connecting members connect the enclosure at a distance to a fuselage of the unmanned flying vehicle, and adapting the device to be arranged in a single-use flying vehicle.
