Abstract
The objective of this work was to experimentally investigate the influence of high filling ratio on the performance of the pulsating heat pipe in the favorable vertical position. R134a with filling ratios of 95%, 90% and 85% was used as working fluid. The pulsating heat pipe had presented one turn in the adiabatic section, one turn in the condenser and one in the evaporator. The results showed that for all filling ratios the pulsating heat pipe work properly. The measured equivalent thermal conductivity ranged from 10 to 52 kW/m.K which are quite high values.
