The Institute of Metal Research at the Chinese Academy of Sciences, in collaboration with the Belarusian Academy of Sciences and Jiangxi Naile Copper Industry Co., Ltd., has developed a novel heat pipe manufacturing technology based on electrochemical deposition additive manufacturing. This breakthrough solves the international challenge of in-situ forming a "gradient porous copper wick" inside an Ω-shaped grooved heat pipe. The team immersed the Ω-shaped copper tube in a specialized copper salt solution, and by precisely controlling the current and time, enabled copper ions to "grow" layer by layer on the groove surface, naturally forming a continuous gradient where pore sizes range from tens of nanometers to several micrometers. The capillary suction force of the wick prepared by this technology is twice that of traditional copper powder sintered structures. With the new wick, the single-tube heat dissipation power of the Ω-grooved heat pipe is doubled compared to traditional straight-grooved pipes. This technology achieves a robust one-step integration of the gradient wick and Ω-groove, completely resolving issues such as poor structural compatibility and high interfacial thermal resistance found in conventional processes.
