Patent
A method for cooling electronic components in an unmanned flying vehicle and a device for carrying out the method
TLDR
In this article, a liquid cooling medium is applied to a control unit in an unmanned flying vehicle (UAV) when the temperature of the electronic components exceeds a predetermined level, in order to spray them directly upon the desired level of cooling.Abstract:
A device for cooling electronic components (8) of a control unit in an unmanned flying vehicle comprises a container (12) containing a liquid cooling medium, means (10) adapted to sense the temperature of said electronic components during the flight of said vehicle and means (13) adapted to be controlled by said temperature sensing means to spray said liquid cooling medium directly upon said electronic components when the temperature thereof exceeds a predetermined level.read more
