The present disclosure relates to a method for manufacturing a heat transfer tube comprising nanostructures formed on the surface, 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.
