The purpose of the work is the development, fabrication and thermophysical studies of experimental samples of gravitational aluminum heat pipes with a threaded capillary structure that could be manufactured at existing domestic enterprises. Methods of research - experimental methods of research using modern means of measuring heat transfer parameters. For the first time, new design and technological solutions for the creation of gravitational aluminum heat pipes with a threaded capillary structure, which, unlike existing aluminum heat pipes with omega-shaped grooves, are more technologically advanced in production, which makes it possible to manufacture them in the conditions of existing enterprises, is cheaper their production and increases their competitiveness. Design sketch documentation for the heat pipe, heat flow simulator and LED light was developed. Five experimental samples of heat pipes with heat carriers were created and investigated: chladone 141b, n-pentane and isobutane. Based on the results of thermophysical studies, an engineering calculation technique and recommendations for the introduction of aluminum heat pipes with threaded capillary structure in LED lighting devices have been developed. Areas of application - lighting, technical thermophysics, housing construction, manufacturing (lighting products).
