Abstract | ||
In recent centuries energy has become of great importance due to the shortage of energy resources and energy losses. Efficient use of energy and minimizing energy waste has become one of the largest research purposes and achieving this goal has provided the field of production of the devices. In this research, the construction of a high-temperature heat pipe with mercury as the working fluid as well as CFD simulation of the heat pipe is investigated and the obtained results are presented. The factors affecting the heat transfer of the heat pipe, including the evaporator and condenser internal heat transfer coefficients and the thermal conductivity coefficient are empirically and numerically investigated and the results are reported as the diagram. The results show that the heat pipe in the heat flux of 278 watts has an efficiency of 0.89 and has the lowest thermal resistance (R=1.3 °C/W) against the heat transfer, which has a better performance than the lower input heat fluxes. The heat pipe built in temperature range close to the design conditions delivers more acceptable performance. | ||
