Patent ID: 7967249

Claim:
Aircraft having a cooling device for expelling heat from a heat source located in the interior of said aircraft to a heat sink, comprising: a first piping system sealed against the surrounding atmosphere, the first piping system having a heat intake section thermally coupled with the heat source, a heat output section thermally coupled with the heat sink, and an essentially adiabatic conveyance section located therebetween, whereby the first piping system is filled with a heat conveyance medium which, when heat is received in the heat intake section from the heat source, undergoes a transition from the liquid phase to the gaseous phase, then flows into the heat output section, then condenses when discharging heat to the sink, and then flows back to the heat intake section, wherein said heat sink includes a section of an external wall of the aircraft; at least one heat exchanger which operatively couples the first piping system to the heat source, thereby to cause heat transfer in the heat intake section; a ventilator operatively connected to said at least one heat exchanger, the ventilator adapted to control the transfer of heat between said at least one heat exchanger and the heat source; a temperature sensor located adjacent the heat source so as to detect the temperature thereof, the temperature sensor operatively connected to the cooling device so that the cooling device can respond to the temperature detected by the temperature sensor; a cold storage unit provided between the heat source and the heat sink, the cold storage unit collecting cooled liquid phase heat conveyance medium for use when cooling requirements are increased, such as when the aircraft is on the ground; and a second piping system sealed against the surrounding atmosphere, the second piping system having a heat intake section thermally coupled with the heat source and a heat output section thermally coupled with the heat sink, whereby the cold storage unit is located in a secondary closed circuit defined by the second piping system.
