Abstract

The invention discloses an aircraft skin heat exchanger. The aircraft skin heat exchanger comprises a shell, a liquid inlet cavity, a liquid collecting cavity and multiple liquid microchannels. The shell contains an outer surface and an inner surface which are fixedly connected to form a sealed cavity. The shell is arranged on the outer surface of the outer skin of a fuselage and is fixedly connected to the fuselage. The multiple liquid microchannels are arranged inside the sealed cavity. One end of the each liquid microchannel is provided with the liquid inlet cavity communicated with the liquid microchannel, and the other end of the liquid microchannel is provided with the liquid collecting cavity communicated with the liquid microchannel. A liquid flows in through the liquid inlet cavity and flows to the liquid collecting cavity through the multiple liquid microchannels and flows out of the liquid collecting cavity. the invention has the following beneficial effects: heat of a liquid is taken away by the air so as to minimize aircraft fuel penalty by the system, heat exchange efficiency is high, concentrated thermal radiation and radar heat reflection area can be reduced, and aircraft stealth performance requirement can be met.

Description

technical field [0001] The invention relates to the technical field of aircraft heat exchangers, in particular to an aircraft skin heat exchanger. Background technique [0002] At present, there are two kinds of technologies close to this patent in the environmental control system at home and abroad: [0003] 1) Air-liquid heat exchanger (abbreviation: air-liquid heat exchanger) - use ram air inlet to cool the thermal fluid from electronic equipment. At present, most aircrafts at home and abroad adopt this form . [0004] Disadvantages: The air-liquid heat exchanger has a large volume and a high height (usually greater than 100㎜), the ram inlet and the ram air have a large aerodynamic resistance on the aircraft, and the air in the ram inlet has a greater impact on the aircraft. Fuel compensation loss. [0005] 2) Air-air skin heat exchanger (abbreviation: air skin heat exchanger) - when hot air flows in the interlayer between the outer skin of the aircraft and the fuselag...
