Краткое описание

The flat horizontal polymer loop thermosyphon with flexible transport lines is suggested and tested. The thermosyphon envelope consists of polyamide composite with carbon nanofilaments and nanoparticles to increase its effective thermal conductivity up to 11 W/m °C. Rectangular capillary grooves inside the evaporator and condenser are used as a mean of heat transfer enhancement. The working fluid is R 600. It was found that in a flat grooved evaporator the thermal resistance Rev of the polymer thermosyphon is of the same order of magnitude as in a classical aluminum smoothly grooved heat pipe evaporator. The thermosyphon evaporator and condenser have a long service life and good wettability and are similar in their design.
