Zusammenfassung:	PURPOSE: A method of manufacturing ultra-hydrophilic metallic pipes using anodic oxidation is provided to enhance cooling efficiency by enhancing wettability of an ultra-hydrophilic metallic pipe with refrigerant and save energy. CONSTITUTION: A method of manufacturing ultra-hydrophilic metallic pipes using anodic oxidation is as follows. The surface of a metallic pipe is electro-polished. Nano pores irregularly engraved by a first anodic oxidation process are formed on the metallic pipe. The surface of the metallic pipe formed as nano pores is removed by an etching process. Nano pores regularly engraved by a second anodic oxidation process are formed on the surface of the metallic pipe.
