[0023] The technical solution of the present utility model will be further specifically described below through examples and in combination with the drawings.

[0024] Example:

[0025] A porous wicking core based on conformal metal super material, comprising a pipe body 1, a wicking core 2 is sleeved in the pipe body 1, and the pipe body is preferably made of copper material;

[0026] In a preferred embodiment, the wicking core 2 includes a porous structure 3 using conformal design, and the voids of the porous structure 3 are filled with metal super material;

[0027] In the design, the model of the wick 2 is meshed to facilitate subsequent design and optimization.

Specifically, by adjusting the unit cell geometry of the metamaterial, such as selecting octet-truss conformal lattice materials, the number of flow channels and effective surface can be increased while maintaining a large surface area. Through fine adjustment of the microstructure, the performance of the wick 2 can be customized according to different application requirements, with higher flexibility.
