The main function of the lap joint-type flat micro-heat pipe was to transfer the absorbed solar energy by the evacuated tubes to the paraffin stored in thermal storage tank or to deliver the heat to the airflow channel. The results show that efficiency of thermal energy storage ranged between 56.1% and 67.5% during the experiments.
The thermal energy storage section with Therminol 55 as sensible heat storage was kept within the common condenser unit of the heat pipe. The condensation of the heat pipe working fluid takes place directly over the thermal energy storage unit.
This study aims to present a novel thermal energy storage integrated evacuated tube heat pipe solar air heater suitable for high-temperature applications. A new heat pipe arrangement was introduced in this study by attaching all the evaporator tubes of heat pipes to a common condenser section.
Water is used as the working fluid inside the heat pipe. The thermal energy storage section is positioned inside the common condenser unit of the heat pipe. The condensation of the working fluid (water) within the heat pipe takes place directly over the thermal energy storage section.

A new heat pipe arrangement was introduced in this study by attaching all the evaporator tubes of heat pipes to a common condenser section. A thermal energy storage medium was kept in a chamber within the common condenser unit of the heat pipe to obtain uniform outlet air temperature from the system when there is fluctuation in solar radiation.
