Title:
航空機用冷却システム
Document Type and Number:
Japanese Patent JP4265008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling system in which a plurality of heat transfer media, e.g. fuel and ram air, can be used as a heat sink for cooling a first heat transfer medium and fuel consumption of an aircraft can be reduced in operation. SOLUTION: In order to use a plurality of heat transfer media, e.g. fuel and ram air, as a heat sink for cooling a first heat transfer medium having high temperature and pressure through compression by means of a compressor 3 in a system for cooling an apparatus (heat load) having a high generation rate using a vapor cycle, a fourth heat transfer medium circulation passage 18 for cooling a first heat exchanger 1 is provided and a fourth heat transfer medium is circulated by means of a pump 19. A third heat exchanger 21 for cooling the fourth heat transfer medium with fuel and a fourth heat exchanger 22 for cooling the fourth heat transfer medium with ram air are arranged in that pipeline. Fuel is used as a heat sink when an aircraft is stopping on the ground or flying at a low speed whereas fuel and ram air are used as a heat sink when the aircraft is cruising thus realizing an operation where ram air intake causing drag on the fuselage is minimized.
