Abstract: This research focuses on the construction and experimentation of a high-temperature cascade heat tubing. The performance of two combinations of Cesium, Potassium, Sodium (CPS) heat pipes and Sodium, Cesium, Potassium (SCP) cascade heat pipes was investigated and compared. Items that can be used in heat pipes and fluids have been chosen. Both single and multistage heat pipe tests were carried out using CPS and SCP, respectively. In this study, single and multistage heat pipes with variable energy inputs of 500, 1500, 2000, and 2500 W are used. A contact non-conduct temperature thermometer and system were used to calculate the first, second, and third fluid and axial temperatures. Temperature and pressure data were obtained using a temperature data logger. The results of the experiments show that a steady-state temperature was reached after 45 seconds per step. Second, the tests' results were used to determine the efficiency and measure the heat pipes' operating range. A multistage heat pipe using these salts produced temperatures ranging from 410 to 710 degrees. The cascaded heat pipe would be suitable for temperatures up to 500 degrees Celsius. A multistage heat pipe-heat exchanger increased temperature efficiency by 18.3 percent over a single-stage heat pipe-heat exchanger.
