Abstract
The aim of this research to assess the thermal performance of a locally developed two-phase closed thermosyphon system charged with methanol. The performance of the system is examined through experiments to determine the impact of changes in the electrical heat power, liquid charge, flow rate, inclination angle, and cooling water temperature on the output temperature. Temperatures at various points of the heat pipe, as well as cooling water, are recorded. Several fluid loadings are examined, ranging from 4 to 9 ml, which corresponds to the limits of the half full and overfilled evaporator. Different flow rates in the interval 0.2–0.7 kg/min, heat input in the interval 13.0–41.4 W, and cooling water temperature in the interval 15–35°C are considered. According to the findings, the ideal liquid fill ratio provides the best results in terms of the output temperature, and the heat transfer coefficient is between 64 and 71%. The impact of the adiabatic zone insulation on the temperature distribution along the heat pipe is illustrated.
