In this study, fabrication of the two-phase closed thermosyphon with annulations grooved wick and forced convection air cooled by inside thermosyphon. Discussion to thermosyphon cooler for cooling efficiency with application and will to bring cooled efficiency by two-phase flow phenomenon inside thermosyphon. Research for a entire height is 93.85mm two-phase closed thermosyphon were had vapor channels, grooved wick, identity of tube to make up. D.I. water was used as the working fluid. Grooved wick structure had annulations array's grooved (0.4mm wide, 2.4mm deep, 80 piece number) by WEDM make. The thermal performance test of the thermosyphon was fabricated a heat sink and fan on identity of tube. Cooling by forced convection air cooled. After evaluation, effect to heat transfer efficiency was important a factor for how much of the filling ratio.
