Heat transport characteristics and liquid flow configuration in a pulsating heat pipe consisting of single, straight tube and having a liquid containing structure in the heating section are investigated experimentally. The effective thermal conductivity increases monotonously with the heating power and becomes approximately 60000 W/(m・K) when the amplitude is approximately ±70mm. A part of liquid film, which forms during the vapor plug growth, flows into the heating section when the plug shrinks. The liquid supply from the heat transport section to the wick of the liquid containing structure in the heating section are shown to be necessary for realizing the successive, stable oscillation with high heat transport characteristics.
