Abstract
This invention relates to the field of micro / nano-structure-enhanced heat transfer surfaces, providing a 3D printing-assisted method and product for fabricating multi-scale three-dimensional metal surface structures. The method includes: fabricating a micron-level high-precision three-dimensional structure mask using 3D printing technology; the three-dimensional structure mask includes a cutout portion and a body portion; the cutout portion matches a three-dimensional structure model; performing material conversion on a metal substrate with the three-dimensional structure mask fixed thereon to obtain a target metal, wherein the metal substrate may be machined beforehand; the target metal surface has a three-dimensional structure matching the three-dimensional structure model. The 3D printing-assisted method for fabricating multi-scale three-dimensional metal surface structures provided by this invention improves the precision of the metal structure by increasing the precision of the template, fabricating multi-scale, multi-material heat transfer structures with micron-level precision and complex structures on the metal surface, thereby improving the metal phase change heat transfer efficiency.
