The range of temperature of heat pipes that are generally used nowadays is between -150℃ and 350℃ and they belong to low-temperature heat pipes. Therefore there are many materials about the working fluid of these heat pipes. But more researches about working fluid are needed in the wide range of temperature with the extension of the use of heatpipes. Especially the researches and materials about the working fluid between 400℃ and 1000℃ which can be used to operate a boiler are much more needed. If we see the working fluid of middle-high temperature heatpipes, we can tell the degree of mercurial content. But it is not so easy to use mercury in the experiment because of the danger of dealing with it. The purpose of this experiment is to compare and evaluate the characteristics of several working fluids which are used between 400℃ and 1000℃ according to the variation of heating temperature and the inclinatory degree of heatpipes. Before making this experiment, I carried out an experiment In which range of temperature Dowtherm - that is largely used as a middle-high temperature working fluid - has the highest efficiency? according to the variation (500℃ ~ 1000℃) of only heating temperature. And I will compare and evaluate which working fluid is more appropriate than other working fluids under the given condition in the next experiment.

저온에너지 회수용 히트파이프의 작동유체 특성에 관한 연구

The resources which is limit loses and the research of alternative energy actively is become accomplished. Also the method which uses the waste heat which the wool which it will write comes to think without again is discussed. Also uses fossil fuel and as plentifully to get neither the environment problem against the CO₂ which becomes will be able to think. Being a break with that reason, it used the heat pipe which is heat transfer machine of the high performance and the test research against the method low-density heat-source frequency it did. Low-density heat-source of the entrance it will measure consequently in temperature and the possibility where it will know the use effect of energy it was. Also gave the change of flow and enthusiasm delivery efficiency of heat pipe which made working fluid with the acetone comparison and it will be able to analyze. Against the method which from this time research applies low-density heat-source with alternative energy it will be able to confirm as a numerical value.
