© 2016 Columbia International Publishing. This study investigated the thermal efficiency and thermal resistance of two-phase closed thermosyphons exhibiting surfaces with various wettabilities in the condenser and evaporator sections. Nano silica particles were coated to vary the wettability of the surfaces. The experimental results revealed that, in the surface of the evaporator section, thermal efficiency increased with an increasingly wettable surface; however, in the condenser section, thermal efficiency decreased with an increasingly wettable surface. The highest thermal performance of the two-phase closed thermosyphon was achieved when the evaporator section was superhydrophilic and the condenser section was superhydrophobic.
