Разработаны фитили из сеток различного переплетения (полотняного, саржевого, перевивочного и петельного) с улучшенными гидрофильными свойствами и вторичной капиллярной структурой. Тепловые трубы гравитационно независимы, приспособлены для работы в различных условиях ориентации и локализации, обеспечивают передачу тепловых потоков значительной плотности (до 25 Вт/см2 ). Отличительные свойства разработанных тепловых труб по сравнению с традиционными, оснащенными порошковыми фитилями: высокие эксплуатационные характеристики, устойчивость к глубокой заморозке, вибростойкость.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тепловая труба</kwd><kwd>фитиль</kwd><kwd>тепловое сопротивление</kwd><kwd>доза заправки</kwd><kwd>максимальная теплопередающая мощность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat pipe</kwd><kwd>wick</kwd><kwd>thermal resistance</kwd><kwd>charging dose</kwd><kwd>maximum heat flux</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cengel, Y.
