Abstract
Heat pipes with mesh wicks were designed (working liquid – water, envelope – copper tube). Wicks from the mesh of various weaves (plain, twill, leno and looped) with improved hydrophilic properties and secondary capillary structure were developed. Heat pipes are gravity-independent, adapted to work in various conditions of orientation and localization, and provide the transfer of high heat flux powers (up to 25 W/cm2 ). The peculiar properties of the developed heat pipes in contrast to the traditional heat pipes (with powder wicks) are: high performance characteristics, resistance to deep freezing; vibrostability.
