Description

Изобретение относитс  к тепловым тру бам, которые используютс  в качестве трансформаторов тепловых потоков. Известны коаксиальные тепловые трубы с капилл5фно-пористой структурой на внут ренних стенках корпуса, которые могут осуществл ть как концентрапию, так и деконцентрацию тепловых потоков. Такие трубы сложны в изготовлении, Известны гладкостенные коакскальные те ловые трубы, установленные с возможностью вращени , используемые также как концентраторы тепловых потоков. Такие трубы требуют дополнительных энергозатрат на привод. Известны тепловые трубы, содержащие вертикальный цилиндрический корпус с кон денсадионной зоной у его стенок и размешенный по оси корпуса нагреватель, образующий на примыкающем к нему участке испарительную зону. Цель изобретени  - интенсификаци  теп лопереноса. Это достигаетс  тем, что в корпусе осесимметрично установлена открыта  с верхнего торца вставка, образующа  гревателем щелевой кольцевой зазор к имеюща  на боковой поверхкостп в н5г/:1 ней части отверсти , сообщыощке KO.U.UQвой зазор с конденсационной зоной. На чертеже изображена описываема  теплова  труба, 1фодопьный разрез. Коаксиальна  теплова  труба содаржнт вертикальный цилиндрическш корпус 1 с конденсационной зоной 2. у его стенок ц размещенный по оси корпуса нагреватель 3. В корпусе 1 осескмметрично установлена открыта  с верхнего торца вставка 4, образующа  с нагреватепем 3 кольцевой зазор, служащий испарительной зоноИ 5. Вставка в нижней части имеет отверспыо, сообщающие испарительную зону 5 (кольцевой зазор) с конденсационной через слой 7 конденсата. По мере движени  парожидкостной смеси по испарительной зоне 5 вверх количество пара в ней увелич1шаетс , а плотность уменьшаетс . Поток laieeT значительно меньшую плотность, чем конденсат в зоне 2, и скорость потока будет увеThis invention relates to heat pipes that are used as heat flow transformers. Coaxial heat pipes with a capillary-porous structure on the inner walls of the housing are known that can carry out both concentration and deconcentration of heat fluxes. Such pipes are difficult to manufacture. Smooth-wall coaxial thermal pipes, rotatably mounted, also used as heat flow concentrators, are known. Such pipes require additional energy consumption for the drive. Heat pipes are known that contain a vertical cylindrical case with a condensation zone near its walls and a heater placed along the axis of the case that forms an evaporation zone in the adjacent area. The purpose of the invention is the intensification of heat transfer. This is achieved by the fact that an insert is opened in the housing axisymmetrically open, forming a slit annular gap to the heater, at the side surface in n5g: 1 of its opening, in combination with the condensing zone. The drawing depicts the described heat pipe, 1fold cut. A coaxial heat pipe has a vertical cylindrical body 1 with a condensation zone 2. A heater 3 located along its walls is located along the body axis. the lower part has a hole that communicates the evaporation zone 5 (annular gap) with condensation condensate through layer 7. As the vapor-liquid mixture moves along the evaporating zone 5 upwards, the amount of steam in it increases, and the density decreases. LaieeT flow is significantly less dense than condensate in zone 2, and the flow rate will increase
