Abstract – Thermal performance of heat pipe | University

The heat transfer ratio (γ) is found to be a very useful parameter in predicting the thermal performance of a heat pipe absorber. For solar heating applications, the heat removal factor (Fr) of the heat pipe system is apparently lower than that of an equivalent conventional system because of the extra heat transfer surface in the heat pipe system.
