Abstract

The invention discloses a double-layer airplane skin heat exchanger which comprises an outer-layer heat dissipation unit and an inner-layer heat dissipation unit. An air channel is formed between the outer-layer heat dissipation unit and the inner-layer heat dissipation unit. The outer-layer heat dissipation unit and the inner-layer heat dissipation unit each comprise an outer heat dissipation unit surface, an inner heat dissipation unit surface and multiple heat dissipation separation boards. The heat dissipation separation boards are arranged between the outer heat dissipation unit surfaces and the inner heat dissipation unit surfaces to form miniature heat dissipation channels. The same ends of the outer-layer miniature heat dissipation channels and the inner-layer miniature heat dissipation channels are provided with a liquid distribution cavity communicated with the ends, and the other ends of the outer-layer miniature heat dissipation channels and the inner-layer miniature heat dissipation channels are provided with a liquid collection cavity communicated with the ends. The double-layer airplane skin heat exchanger is installed on the outer surface of an airplane body skin. The double-layer airplane skin heat exchanger has the beneficial effects that heat of liquid is taken away through air, the fuel oil compensation loss caused by a system to an airplane is reduced, heat exchange efficiency is high, the concentrated heat radiation area and the radar heat reflection area can be reduced, and the requirement for the stealth performance of the airplane can be met.

Description

technical field [0001] The invention relates to the technical field of aircraft heat exchangers, in particular to a double-layer 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...
