Abstract

This work studies the inclination angle effect on the two-phase closed thermosyphon (TPCT) with semicylindrical condenser internal fins. The finned thermosyphon thermal performance is studied at two different inclination angles 30o and 60o. Water is the working fluid for different filling ratios (FR) of 20, 50 and 80. The experiments are performed at different input power levels. The thermosyphon temperature is measured and both the heat transfer convection and condensation coefficients are calculated. In addition, the overall heat transfer coefficient is calculated and used as an indication of TPCT thermal performance. The lowest thermal resistance occurred at 50% FR at an inclination angle of 30o. The results showed that, at 60o inclination angle the average temperature of the thermosyphon is slightly lower than the 30o. The thermal performance of the TPCT is superior at 80% FR for 600 inclination angle as it achieves the highest overall heat transfer coefficient at this condition. Based on the overall heat transfer coefficient values, The thermal performance of inclined TPCT is higher at inclination angle 60° compared to 30o inclination angle.
