A new mathematical model of a system of cylindrical heat pipes with a composite wick is presented. The results of numerical modeling and experimental studies of a heat pipe system (SHP) to ensure the removal of a given thermal power from radio-electronic equipment for various purposes are presented, and its minimum mass is determined. The limiting values of the removed thermal power of a single heat pipe, a two-level CTT under the conditions of a gravitational field are established. According to experimental data, the STT is capable of removing 667 W/kg from a height of 0.11 m at a temperature of minus 5 °C, 910 W/kg at a temperature of plus 40 °C. The presented results of the work make it possible to optimally solve many engineering problems related to the transfer of thermal power with minimal losses, cooling and temperature control or thermal stabilization of various objects used both on Earth and in outer space.
