This paper describes an experiment in the analysis of the heat transport characteristics of a downward heat transport device utilizing the vapor pressure change as the liquid pumping force. The condensate stored in the accumulator returns to the evaporator because of the pressure difference between the accumulator and the condenser produced by unsteady evaporation due to the change of the liquid volume in the evaporator. The vapor pressure in the evaporator was restricted by the accumulator pressure which was almost constant because of the effect of the noncondensable gas, and good temperature control capability was obtained through the passively changing effective condenser length just as in a variable conductance heat pipe. The temperature control capability and the effective condenser length were predicted by the analysis of the simple operation model and the theoretical results agreed well with the experimental data.
