An experimental investigation for a heat pipe with axial"Omega"-shaped micro grooves was conducted to study the axial distribution of wall temperature,effective thermal conductivity,total thermal resistance,heat transfer coefficient and maximum heat transport capability.The results indicated the heat pipe has powerful heat transfer capability,and high degree of temperature uniformity.And the ability of long distance heat transfer was verified.The maximum heat transport capability is influenced by the working temperature;the heat transfer performance is relatively better at low temperature while it is deteriorated at the high temperature.
