A Study on the Condenser Temperature Characteristics of a Disk Type Heat Pipe

원판형 히트파이프의 응축부 온도 특성에 관한 실험적 연구

An experimental study was conducted to investigate an isothermal characteristics of the condenser surface of disk type heat pipe using PF 5060 and FC 40 as working fluids. Desired temperature range at the condenser surface was $90^{\circ}C{\sim}130^{\circ}C$, which was cooled by natural convection. The operating temperature, the height of vapor space, the wall thickness of condenser, and the existence of a wick structure were considered as experimental factors. The temperature difference and the temperature fluctuation at the condenser surface were analysed to describe the performance of the heat pipe.
