Air cooling device for cooling air in turbine engine of aircraft, has air/fuel exchanger including air flow tube and fuel flow tube, where cooling system and fuel circuit of turbine engine cross each other in device

摘要

The device (30) has an air/fuel exchanger including a tube (40) in which air flows, and another tube (41) in which fuel flows, where the tubes are in contact with each other. A cooling system (14) and a fuel circuit (21) of a turbine engine (10) cross each other in the device, where the device is positioned between air bleeding ports (15) on a high pressure compressor (11) of the turbine engine, and air re-introduction ports (16, 17) on turbines (12, 13) of the turbine engine. The air flow tube is made of a conductive material such as metal.
