The present disclosure relates to a heat transfer tube having rare-earth oxide deposited on a surface thereof and a method for manufacturing the same, in which the rare-earth oxide can be deposited on the surface of the heat transfer tube to implement a superhydrophobic surface even under the high temperature environment and a plurality of assembled heat transfer tubes can be coated by coating a complex shape by depositing rare-earth oxide using a method for dipping a surface of the heat transfer tube and coating the same, thereby reducing or preventing the heat transfer tubes from being damaged during the assembling of the heat transfer tubes after the coating.

Heat transfer tube having rare-earth oxide superhydrophobic surface and method for manufacturing the same

The present disclosure relates to a heat transfer tube comprising nanostructures formed on the surface, and a method for manufacturing the same, and by forming nanostructures on a heat transfer tube surface, a superhydrophobic surface may be obtained under a high temperature environment as well. In addition, superhydrophobicity may be enhanced by further forming a hydrophobic coating layer on the nanostructure-formed heat transfer tube surface. By using a method of forming nanostructures by dipping the heat transfer tube surface, complex shapes may be coated, and therefore, a plurality of assembled heat transfer tubes may be coated, and damages occurring during a process of assembling the heat transfer tube after coating may be prevented.
