A new heat pipe, which is applied to radiant floor heating system, ＇s presented by anatyz- ing the characteristics of the heat pipe. The steam flow and condensate flow are separated in this heat pipe, avoiding the phenomenon of flooding limit. The areas of evaporation section and condensation section can be changed according to the demand. The radiant floor heating system with the technology of heat pipe can improve heat transfer and reduce water temperature, which can reduce energy consumption and provide ref- erence for researches of heating system utilizing low grade energy.
