Description

Изобретение относитс х теплопереда- ющим устройствам, в частности к тепловым трубам.The invention relates to heat transfer devices, in particular to heat pipes.

Цель изобретени - при сохранении термодиодного эффекта повысить теплопе- редающую способность конденсационной зоны, The purpose of the invention is, while maintaining the thermodiode effect, to increase the heat transfer capacity of the condensation zone,

Теплова труба содержит зону испарени 1, зону конденсации 2 с центральной трубчатой вставкой 3, капилл рную структуру 4, с гофрами 5, отверсти 6 перфорированные в капилл рной структуре, гофры на поверхности трубы 7 и перегородку 8 и паровой коллектор 9,The heat pipe contains an evaporation zone 1, a condensation zone 2 with a central tubular insert 3, a capillary structure 4, with corrugations 5, holes 6 perforated in the capillary structure, corrugations on the surface of the pipe 7 and a partition 8 and a steam manifold 9.

Теплова труба работает следующим образом. Пар из зоны испарени (при подведении тепла) двигаетс по паровым каналам и поступает в коллектор 9 и далее через отверсти 6 в зону конденсации 2, Обтека трубчатые вставки пар конденсируетс (при отводе тепла) и конденсат ст гиваетс с цилиндрической поверхности вставок гофрами 5 капилл рной структуры 4 и по капилл рной структуре возвращаетс в зону испарени .The heat pipe works as follows. The vapor from the evaporation zone (when heat is supplied) moves through the steam channels and enters the collector 9 and then through the openings 6 to the condensation zone 2, the streamline of the steam inserts condenses (when heat is removed) and the condensate is compressed from the cylindrical surface of the inserts by capillary corrugations 5 structure 4 and capillary structure returns to the evaporation zone.

Положительный эффект изобретени состоит в увеличении теплопередающей способности трубы за счет эффективной организации подвода пара в зону конденсации через отверсти и интенсивного отсоса пленки конденсата, с цилиндрической поверхности центральных трубчатых вставок с помощью гофрированной капилл рной структуры.A positive effect of the invention is to increase the heat transfer capacity of the pipe due to the efficient organization of the steam supply to the condensation zone through the holes and the intensive extraction of the condensate film from the cylindrical surface of the central tubular inserts using a corrugated capillary structure.

Изготовленный вариант предлагаемого изобретени имел следующие размеры.The manufactured embodiment of the invention had the following dimensions.

Испарительна часть: длина 400 мм; ширина 100 мм; толщина 3 мм;Evaporative part: length 400 mm; width 100 mm; thickness 3 mm;

конденсаторна часть длина 140 мм; ширина 100 мм; толщина 20 мм; диаметр трубчатой вставки 14 мм; теплоноситель вода .condenser part length 140 mm; width 100 mm; thickness 20 mm; the diameter of the tubular insert 14 mm; coolant water.

Проведенные испытани показали следующие результаты:The tests performed showed the following results:

при общем теплосъеме 300 Вт температуры испарительной части 30°С и конденсаторной 27°С.with a total heat removal of 300 W, the temperature of the evaporation part is 30 ° С and the condenser part is 27 ° С.
