Although numerous works have been carried out in the field of high temperature applications, there is a lack of sufficient data on the actual thermal performance of thermosyphons for low input heat especially the geometric effects and inclination angle under normal operating conditions. Therefore, it is the objective of this work to examine the thermal behaviors in a thermosyphons by taking into consideration the evaporator geometry, inclination angle of tube, coolant flow rate and filling ratio. To obtain this objective, distilled water was used as the working fluid and two copper tubing of inside diameters of 14 and 20 mm with different ratios of evaporator length to the inside diameter of 15, 20 and 29.3 were implemented in this work. In addition, the temperature distribution along the thermosyphons, input heat to the evaporator and output from the condenser section was monitored. The results reveals that the thermosyphons has the highest rate of heat transfer in the inclination angle of 60° for all the three aspect and filling ratios adopted in this work. Furthermore, a good agreement was observed between the experimental results of the present study and the previous published correlations.
