Abstract: This study, by using ejector, deals with improvement of energy and exergy performance of thermosyphon heat pipes. For this aim, an ejecting thermosyphon heat pipe with short vapor pipe (ETHP-SP), an ejecting thermosyphon heat pipe with tall vapor pipe (ETHP-TP) and a conventional thermosyphon heat pipe (CTHP) are designated and manufactured for heating air and they are experimentally investigated under different airflow velocities but with the same heat input and filling rate. While the lowest energy and exergy performance occur in the ETHP-TP, the highest energy and exergy performance occur in the ETHP-SP. Under different airflow velocities which are determined as 3.3, 5.3 and 6.3 ms-1, by using ejector with short vapor pipe in the conventional thermosyphon heat pipe, energy performance of CTHP increases by 5.9%, 8.7% and 9.6 respectively. In addition, exergy performance of CTHP goes up by 8%, 7.1% and 13.6% respectively.
