Изобретение относитс к тёплопередающим устройствам.This invention relates to heat transfer devices.

Известна электрогидродинамическа теплова труба, содержаща частично заполненный теплоносителем герметичный корпус с зонами испарени и конденсации , разделенными поперечной перегородкой и соединенными между, собой посредством конденсатопровода и парового канала,, и закрепленный на перегородке жидкостный насос с . двум последовательно расположенными вдоль оси корпуса и контактирующими между собой по .торцам пьезоэлементами , снабженными электродами П).The electrohydrodynamic heat pipe is known, which contains a hermetic body partially filled with heat carrier with evaporation and condensation zones separated by a transverse partition and connected between, by means of a condensate line and a steam channel, and a liquid pump mounted on the partition. two piezoelectric elements in contact with each other along the axes of the housing and fitted with electrodes P).

Недостатками этой трубы вл ютс сложна конструкци и от носи т ель не низка -надежность, обусловленные наличием большого числа конструктивных элементов, обеспечивающих создание в. конденсатопроводе бегущей волны деформации его стенки. The disadvantages of this pipe are complex construction and the bearing is not low - reliability, due to the presence of a large number of structural elements, ensuring the creation of. condensate line traveling wave deformations of its wall.

Цель изобретени - упрощение конструкции при одновременном повышении надежности.The purpose of the invention is to simplify the design while improving reliability.

Эта цель достигаетс тем, что каждый пьезоэлемент выполнен в виде двух соединенных боковыми гран ми пластин, причем пьезоэлементы развернуты один относительно другого на 90° и на свободном торце пьезоэлемента , размещенного со стороны зоны кон10 денсации, с зазором относительно стенки корпуса установлен цилиндрический вытеснитель, а зона конденсации на участке последнего выполнена в виде улитки.This goal is achieved by the fact that each piezoelectric element is made in the form of two plates connected by side edges, the piezoelectric elements are turned one relative to the other by 90 ° and a cylindrical propellant is installed on the free end of the piezoelectric element, with a gap relative to the housing wall, the condensation zone on the site of the latter is made in the form of a cochlea.

Claims

The heat pipe contains a sealed enclosure 1 with zones 2 and 3 of evaporation and condensation, respectively, separated by a transverse partition i and connected between the condensate conduit 5 and the steam channel 392 in the form of a branch pipe 6. On the partition 4 a liquid pump 7 is fixed with two successively located along the axis of the housing 1 and piezoelectric elements 8 and 9 which are in contact with each other according to the end faces, each of which is made in the form of two plates connected by lateral faces, with piezoelectric element 9 being rotated relative to piezoelectric element 8 by 90 and A cylindrical propellant 10 is placed on the free end; it is placed with a gap relative to the wall of the housing 1, and the condensation zone 3 at the site of the propellant 10 is made in the form of a cochlea. The electrodes 11 and 12 are placed on the lateral faces of the plates forming the piezoelectric elements 8 and 9. A wick 13 is placed on the inner surface of the housing 1 in the zone 2 of evaporation. The heat pipe works as follows. When heat is supplied to the evaporation zone 2, the coolant evaporates and its vapor through pipe 6 enters the condensation zone 3, where, condensing on the wall of the housing 1, it gives off heat, the alternating voltages shifted by a quarter of the period 11 and 12 which bending deformations of piezoelement 8 and. 9, in mutually perpendicular planes, they create a circular motion of the displacer 10, by means of which condensate is pumped through the cochlea into the condensate conduit 5 and then into the evaporation zone 2,. Due to the significant reduction in the number of structural elements, the design of the heat pipe is simplified and its reliability is increased. The invention of an electrohydrodynamic heat pipe containing a hermetically sealed enclosure partially filled with heat carrier with evaporation and condensation zones separated by a transverse partition and interconnected by means of a condensate line and a steam channel and fixed on the partition liquid pump with two consecutively arranged along the axis and in contact with each other piezoelectric elements fitted with electrodes, distinguished by the fact that, in order to simplify the design while but increasing reliability, each piezoelectric element is made in the form of two plates connected by side edges, the piezoelectric elements are rotated 90 ° relative to each other and a cylindrical displacer is installed on the free end of the piezoelectric element located on the side of the condensation zone plot last made in the form of a snail.
