The invention provides a novel aircraft airfoil high-temperature heat transfer system, and relates to the technical field of hypersonic aircraft thermal protection. A novel aircraft wing type high-temperature heat transfer system comprises an outer shell, a capillary core and an inner supporting structure, the outer shell does not comprise a cover plate at the joint of the outer shell and an aircraft body and is integrally formed through 3D printing, the connecting cover plate can be manufactured through 3D printing or machining, the outer shell and the connecting cover plate are welded together to form a steam cavity, and alkali metal working media are filled in the steam cavity. Integrated manufacturing is carried out through the 3D printing technology, the contact thermal resistance between the heat pipe and an air rudder and between the capillary core and the shell can be effectively removed, the heat conduction capacity of the heat pipe is enhanced, the porous lattice structure serves as a supporting structure, the overall strength is improved, the weight is reduced, the porous lattice structure has the ultra-large surface area, the heat exchange capacity is enhanced, and the heat exchange efficiency is improved. The backflow capacity of the working medium is enhanced, and the deformation problem caused by traditional machining and welding is reduced.
