영문 초록

The purpose of this study is to secure possibility that can be applied to heat exchanger for industry, by measuring thermal performance of TPCT(Two Phase Closed Thermosyphon), which was made by simplifying the making procedure and method. For this study, TPCT-typed heat exchanger was made, which comprised a copper pipe with length in 600mm, inner diameter in 8mm, outer diameter in 9.52mm, adiabatic section length in 320mm, and length of evaporator and condenser section in 120mm, respectively. Also, for heating and cooling the evaporator and condenser section, the water jacket was made with a copper pipe, which is 120mm in length and 28.58mm in outer diameter. The working fluid was used distilled water. 15% of the whole volume was charged. For heating evaporator and cooling condenser, hot water and cold water were used, respectively. To measure the temperature in the surface of TPCT and in the inlet ＆ outlet of hot and cold water, it attached 13 temperature sensors and calculated the heat transfer rate of TPCT. As a result of surveying each thermal performance through experiment as for a case that the temperature of inlet in hot water jacket of evaporator is 60℃, 70℃ and 80℃ and that an angle of inclination in TPCT is 22.5°, 45° and 90° from horizontality. TPCT was confirmed to have the maximum heat transfer performance given being 80℃ in the temperature of hot water and being 22.5℃ in the inclination from horizontality.
