Theory of a rotating heat pipe

Abstract

Based on a simple model, an analytical solution was obtained to predict the heat transfer rate of a wickless heat pipe which is conical in shape and rotates about its longitudinal axis. The rotating heat pipe utilizes centrifugal force, instead of capillaries, for the return-pumping of the condensate. The heat transfer rate of the rotating heat pipe is then compared with the existing result of a conventional capillary heat pipe to demonstrate the merit of the former. © 1971.
