Abstract:
This study aims to present a method of reducing heat loss in a two-phase closed thermosyphon (TPCT) by replacing copper tubing with acrylic in the adiabatic section. The designs used included total lengths of (LT) 150, 300 and 450 mm. The evaporator section (LE), Adiabatic section (LA) and Condenser section (LC) lengths were all alike at 50, 100 and 150 mm. The copper and acrylic tubes were of 15 mm external diameter and 12 mm internally. The temperatures applied at the evaporator section (TE) were 60ºC and 80ºC. The angles of inclination were 0º, 20º, 40º, 60º, 80º and 90º, and air velocity at the condenser section was 1 m/s. The working fluid used was plain water with a filling ratio of 50% of the evaporator section volume. The experiment showed that as TE increased so did heat flux, however shorter LTs resulted in lower heat flux, and the maximum heat flux achieved was 5 kW/m2 at TE 80ºC, LE 150 mm, with an angle of inclination at 80º to 90º using acrylic tube in the adiabatic section. When acrylic tube was installed instead of copper tube at LA the resulting thermal resistance (Rtube) Cº/W decreased and heat flux increased. The maximum Rtube result was recorded at around 2.78Cº/W with the acrylic tube of LE 150 mm. with a TE of 80ºC.
