An Experimental Study on the Rotating Heat Pipe with a Grooved Disc Evaporator

홈이 파진 원판증발기를 가진 회전형 히트파이프에 대한 실험적 연구

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.
