The invention belongs to the field of integration of additive manufacturing, design and manufacturing, and particularly relates to a heat pipe type front edge structure of a 4D printed part. Comprising a skin, the skin comprises an outer skin and an inner skin, the inner skin is arranged on the inner side of the outer skin, a containing cavity is formed between the outer skin and the inner skin, a liquid working medium is contained in the containing cavity, and fine and dense lattice structures are arranged on the inner surface of the outer skin and the inner surface of the inner skin; the multiple partition plates are arranged between the outer skin and the inner skin and used for partitioning the containing cavities, through holes are formed in the partition plates, and the through holes are used for circulation of the liquid working media in the adjacent containing cavities; the aircraft body connecting structure is installed on the skin and used for connecting the skin with an aircraft body structure. The thermal protection problem of the front edge structure of the hypersonic flight vehicle can be solved, and the advantages of compact structure, high practicability, high reliability and the like are achieved.
