Description
Изобретение относитс к теплотехнике и может быть использовано при; изготовлении тепловых труб.This invention relates to heat engineering and can be used for; manufacture of heat pipes.
Известна капилл рна структура тепловой трубы, содержаща каналы дл Прохода пара, расположенные даскретно в гидрофильном пористом материале l .The known capillary structure of a heat pipe containing steam passage channels located in the hydrophilic porous material l.
Недостатком данной структуры вл етс то, что Каналы дл прохода пара выполн ютс в виде отверстий в основной массе фитил сверлением, прокалыванием или вырубкой, вследствие чего внешн - поверхность капилл рной структуры вблизи кромок отверстий оказываетс деформированной, что приводит , во-первых, к пор, а во-вторых, к неплотному прилеганию капилл рной струмтуры к поверхности корпуса.The disadvantage of this structure is that the channels for the passage of steam are made in the form of holes in the main body of the wick by drilling, puncturing or cutting, as a result of which the outer surface of the capillary structure near the edges of the holes is deformed, which leads, firstly, to and, second, to the loose fit of the capillary strumture to the surface of the housing.
Известна также капилл рна структура тепловой трубы, выполненна из пористого гидрофильного материала 2,Also known is the capillary structure of the heat pipe, made of a porous hydrophilic material 2,
Недостатком указанной структу ил вл етс то, что паровой поток, проход через капилл рную структуру, захватывает с собой жидкий теплоноситель и выбрасывает его из зоны испарени в паровое пространство, создава дефицит охлаждающей жидкости.The disadvantage of this structure is that the vapor flow, the passage through the capillary structure, takes the heat-transfer fluid with it and discharges it from the evaporation zone into the vapor space, creating a shortage of coolant.
что приводит к снижению термодинамической эффективности.which leads to a decrease in thermodynamic efficiency.
Цель изобретени - повышение термодинамической эффективностиiThe purpose of the invention is to increase thermodynamic efficiency.
Указанна цель достигаетс тем, что капилл рна структура имеет дискретно расположенные участки из гидрофобного материала.This goal is achieved by the fact that the capillary structure has discretely arranged portions of hydrophobic material.
На фиг.1 представлена предлагаема Figure 1 presents the proposed
10 капилл рна структура, общий вид; на фиг.2 - то же, поперечное сечение при расположении на стенке тепловой трубы.10 capillary structure, general appearance; figure 2 is the same, the cross section at the location on the wall of the heat pipe.
Капилл рна структура расположена The capillary structure is located
15 на стенке корпуса тепловой трубы 1, выполнена .из пористого гидрофильного материала 2 и содержит дискретно расположенные участки 3 из гидрофобного материала.15 on the body wall of the heat pipe 1, is made of a porous hydrophilic material 2 and contains discretely located sections 3 of a hydrophobic material.

Предлагаема структура работает следующим образом.The proposed structure works as follows.
В зоне испарени при подводе теплового- потока к стенке тепловой трубы 1 начинаетс парообразование в In the evaporation zone, when heat flux is supplied to the wall of the heat pipe 1, vaporization starts in
25 капилл рной структуре, и образовавшийс .пар выходит через участки 3 в паровое пространство, оставл на стенках капли захваченного теплоносител , который транспортируетс в 25 of the capillary structure, and the vapor formed through the sections 3 enters the vapor space, leaving a drop of trapped heat carrier on the walls, which is transported to
30 зону испарени за счет капилл рных30 evaporation zone due to capillary
