Краткое описание

Heat transfer enhancement in the evaporator of a vapordynamic thermosyphon and loop heat pipe (LHP) filled with propane is discussed. The experimental data for heat transfer with propane pool boiling on horizontal smooth and porous tubes inside the vapordynamic thermosyphon and the LHP evaporator were recorded for saturation temperature Ts = 0−30°C and heat input q = 0.1−120 kW/m2 (q = 0.02−30 kW/m2 for LHP evaporator). Heat transfer intensification up to 3−5 times was obtained with a heat transfer coefficient up to 30 × 103 W/m2.
