HEAT TRANSFER TUBE HAVING RARE-EARTH OXIDE SUPERHYDROPHOBIC SURFACE AND MANUFACTURING METHOD THEREFOR

摘要

The present invention relates to a heat transfer tube having a rare-earth oxide based superhydrophobic surface and a manufacturing method therefor, wherein a rare-earth oxide is deposited on a surface of a heat transfer tube to realize a superhydrophobic surface in a high temperature environment. Moreover, as the rare-earth oxide is deposited with a method of dipping and coating the surface of the heat transfer tube, a complex shape can be coated for a plurality of assembled heat transfer tubes to be coated. Therefore, damage caused in a process of assembling the heat transfer tubes after coating the heat transfer tubes can be prevented.
