The Characteristics of heat transport in the heat pipe with a double vapor path and different kinds of the working fluid were investigated experimentally. The Experiment was carried out with acetone/ethanol. ethanol/ethanol. and in the aluminium container of the double vapor path. Performance measurements can be operated at the high level by 24000 w/m2 heat flux in the 1000mm evaporator. They are each estimated at the high temperature and experimentally reviewed the characteric of the heat rejection. The results shew that they are stably operated under each condition and the fluid was complemented each other at the fluid's experiment and brought about the extention of operating temperature. In this study, The reliable basic data obtained by the teste in the heat pipe with a double vapor path can be used for thermal design, manufacture, and production etc.
