The invention discloses the multistage cooling of an aircraft electronic system () with at least one electronic component which delivers heat. The multistage feature results from the use of a plurality of circuits for transferring the waste heat. An internal coolant () circulating in a closed circuit which is thermally coupled to the electronic component carries heat from the at least one electronic component to a heat exchanger () which delivers the heat to an external coolant which flows and/or circulates from a source outside of the aircraft electronic system () through the heat exchanger () to a sink outside of the aircraft electronic system (). The internal coolant flows from the heat exchanger () in the direction of the at least one electronic component and/or circulates in a closed circuit.

Multistage cooling of electronic components of an aircraft

A cooling system () for cooling an aircraft device () comprises an evaporator () for receiving a fluid (F) which is to be evaporated, a first adsorber () which contains a medium () for the adsorption of the fluid (F) which is evaporated in the evaporator (), as well as a second adsorber () which contains a medium for the adsorption of the fluid (F) which is evaporated in the evaporator (). A control system () is adapted to establish or to interrupt a fluid connection between the evaporator () and the first and/or the second adsorber(s) ().
