SINOPSIS

Heat pipes are passive heat transfer devices that can successfully transfer large amounts of heat. The robust and simple tubular structure with no moving parts makes the heat pipe a perfect choice for different applications such as industrial or aerospace. Heat pipe technology for industrial applications has been widely used on a heat recovery system, with an increasing development for thermal control of electronic equipment and heat exchangers performance augmentation. The heat pipe performance depends on its geometry, working fluid, wick structure, and operating conditions. The working fluid is one of the most important parameters as the heat pipe utilizes the phase change to transport the heat. Therefore, the selection of the working fluid is of great importance to enhance the thermal performance of the heat pipe. Heat pipes operating at mid-level temperatures have found several applications in both industry and aerospace segments. In this study, heat pipes were designed and manufactured with the objective of investigating the potential application of heat pipes operating at mid-level temperature. The thermal conductance obtained from the experimental tests was used to correlate the thermal conductances obtained analytically, with results showing high accuracy based on the adjustment factor applied.
