Pulsating heat pipe (PHP) is a latest development in heat pipe technology. In this paper, evaporation and boiling phenomena are investigated, and liquid heat transport performance in a PHP is measured at different fill ratio as well. The observation results show that phase change in the evaporator may occur by two different mechanisms: 1) evaporation and boiling in thin liquid film on the evaporator wall, 2) generation and collapse of tiny bubbles suspended in the liquid slug. Meanwhile, the temperature measurement indicates that temperature gradient between the evaporator and the condenser is related to liquid latent heat, density, viscosity, and mass filled in.
