Embodiment Construction

[0042] The cooling of aircraft electronic systems will now be described in more detail using the example of an electronic aircraft entertainment system. It will be appreciated that the teachings described below may be applied in any aircraft electronic system.

[0043] figure 1 An electronic aircraft entertainment system 2 (IFE: In-Flight Entertainment) cooled by airflows 8 , 10 , 12 is shown. The fan 16 draws in air 8 from the environment and supplies this air to the heat exchanger 6 . The sucked air 8 is the internal coolant. The heat exchanger 6 is connected to the cooling system via the connection 4 . An external coolant, which may be gaseous or liquid, is supplied to the heat exchanger 6 through the connection 4 . The air 8 supplied by the fan 16 to the heat exchanger 6 is converted into cold air 10 and flows into the electronic aircraft entertainment system 2 . As this air cools the aircraft entertainment system electronic components, the air gradually heats up and ...

Abstract

The invention discloses the multistage cooling of an aircraft electronic system (2) 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 (14) 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 (6) which delivers the heat to an external coolant which flows and / or circulates from a source outside of the aircraft electronic system (2) through the heat exchanger (6) to a sink outside of the aircraft electronic system (2). The internal coolant flows from the heat exchanger (6) in the direction of the at least one electronic component and / or circulates in a closed circuit.

Description

technical field [0001] The present invention relates to multi-stage cooling of electronic components and assemblies in aircraft, in particular electronic entertainment systems. Background technique [0002] In modern airliners, electronic entertainment systems are an essential part of the comfort provided to aircraft passengers. The demands to be met by entertainment electronics depend on the increasing availability of more efficient electronic components, electronic assemblies and computer systems. The concomitant high power density results in an ever-increasing amount of waste heat that must be removed in order to ensure the entertainment electronics can operate for a long time. [0003] Modern electronic systems, especially aircraft entertainment systems, require such large volumes of air to cool these systems that this air cannot always be removed from the surrounding air-conditioned passenger cabin. To cool electronic aircraft entertainment systems, long air ducts are...
