The heat transfer characteristics of the rotating heat pipe with a disc evaporator and a grooved condenser have been investigated by measuring temperature distributions of wall and vapor for various thermal inputs and revolutions per minute. The results showed that the heat transfer coefficients of all types are increased with thermal input and revolutions per minute. The heat transfer coefficient of evaporator with groove (pitch=2.5mm depth=1.5mm) is 25.8% higher than that of evaporator without groove at 500RPM, 150W.
