The invention relates to a heat prevention and insulation structure between a fuselage and wings, the heat prevention and insulation structure comprises at least one heat exchange pipe, the heat exchange pipe comprises an evaporation end and a condensation end, the evaporation end is arranged on the fuselage close to an engine tail flame or a spray pipe, and the condensation end is arranged on the wings needing ice prevention and deicing; the heat exchange pipe further comprises a liquid channel and a steam channel, and the liquid channel wraps the steam channel. Heat exchange is carried out between the fuselage and the wings according to the capillary suction principle. The liquid working medium in the evaporation end absorbs heat transmitted to a nearby fuselage by engine tail flame or a spray pipe, so that the structure temperature is controlled, material selection limitation caused by temperature rise is improved, the heat can be further utilized, meanwhile, the condensation end is arranged at the position of a wing needing anti-icing and deicing, the heat is used for anti-icing and deicing, and the anti-icing and deicing efficiency is improved. Air entrainment of an engine compressor can be reduced, oil consumption increase caused by mass utilization of engine air entrainment in the prior art is avoided, and therefore cost is reduced.
本发明涉及一种机身与机翼间的防隔热结构,防隔热结构包括至少一个热交换管,热交换管包括蒸发端和冷凝端,蒸发端设置于靠近发动机尾焰或喷管的机身处,冷凝端设置于需要进行防冰、除冰的机翼处;热交换管还包括液体通道和蒸汽通道,液体通道包裹蒸汽通道;利用毛细抽吸的原理在机身与机翼间进行热交换。本发明,由蒸发端内的液体工质吸收发动机尾焰或喷管传输到附近机身热量,从而控制结构温度,改善温度升高导致的选材局限性,且可进一步利用这部分热量,同时,通过将冷凝端设置于需要进行防冰、除冰的机翼处,将热量用于防冰、除冰,可减少发动机压气机引气,避免了现有技术中大量利用发动机引气导致的油耗增加,从而降低成本。
