This paper proposes a novel rotating heat pipe which utilizes convective heat transfer instead of boiling and condensation heat transfer, and the Archimedean Screw for water recirculation. The heat pipe consists of the double whose concentric annulus has the screws. The heat transfer experiments were conducted using conducted using four types of pipes of 28 and 37 mm ID, 480 mm long with the screw pitch of 10 and 25 mm for 28 mm ID pipes, and 25 and 75 mm for 37 mm ID pipes. The working liquid was tap water and the volumetric charge was 50-75% of pipe volume. The heat apparent heat transfer coefficient was about 1 100-2 250 w/(m^2・C). This was 37-75% of the rotating heat pipe which has about 3 000w/(m^2・℃) of heat transfer coefficient.
