Description

.one

The invention relates to the power industry, nefgana, gas, and other branches {fomishchpennostk and can be used for 1 razm razivanii frozen soils, heating the rash of their material | in cars, thawing ice, heating electric machines, internal combustion engines and others with students, it is necessary to bring energy from the top down.

Heat pipes are known that contain the main and auxiliary zones and the condensation zones and the transport zone tlj.

A disadvantage of the known pipes is the smaller value of the limiting thermal power, the limited height of raising the liquid against force, and the narrow limits of regulating the thermal load.

The purpose of the invention is to improve the parameters of the pipe, expanding the limits of adjusting the heat load, I increasing the height of the lifting fluid j against the force of gravity.

This is achieved by the fact that the lower part of the transport zone is connected by means of a pipe to the auxiliary zone.

evaporation separated from the auxiliary condensation zone by a capillary-porous rme; wound; the pipeline at the point of connection to the transport zone is provided with a nozzle.

The drawing schematically shows the proposed heat pipe.

The heat pipe contains the main zones I and 2 of evaporation and air flow, transport zone 3, auxiliary zones 4 and 5 of evaporation and condensation, cooTBeTCTBejiHO. The main zone of f sparvnn is separated from the free zone of the 5th series with the ichthorn membrane 6 in the auxiliary zone 4 evaporation is also separated from the auxiliary zone 5 of condensation by the capillary-porous membrane 7. the main evaporation zone 1 and the auxiliary zone 4 of the evaporation zone has a capillary membrane 7. the vaporization zone 1 and the auxiliary zone 4 of the evaporation zone have a capillary membrane 7. 9, respectively, the inner walls.

The transport zone 3 on the outer surface has thermal insulation 1O and the lower part of this 3olai is connected by means of a pipeline 11 to an auxiliary evaporation zone. Pipeline 11 in place connected to the transport zone 3 is equipped with nozzle 12. I connect the ill-porous membranes with the LM / 1COTSYG auxiliary zone 5 | sondvnsacin with the help of capillary-porous wicks 13, the Transport zone 3 is also equipped with thermal insulation 14. Teal tube works as follows; When energy is supplied to the zones 1 and 4 of the exhaustion, the working liquid from the pores of the capillary-porous coating 8 and 9 evaporates, the resulting vapor in the evaporation zone 1 moves into the main zone. 2 condensation, where it condenses, from where the condensate enters the transport zone 3, the vapor from the auxiliary evaporation zone 4 through the nozzle 12 enters the transport zone 3, where a two-phase vapor-liquid mixture is formed. The bubbles of the pen push the saturated liquid out of the translate zone 3 into the auxiliary zone 5 condensing, and the vapor condenses on the cold walls of the 8th zone. The liquid of the auxiliary condensate with the help of capillary filaments 13 enters the capyplone membranes 6 and 7, and then into the capillary-porous coating of 8 n 6 evaporation zones. The invention allows for the transfer of heat energy from top to bottom over a distance of 1-2 cm or more, and also allows the use of a pipe for melting ice, thawing frozen ground during the production of rollers and other valuable metals in frozen ground regions. The economic effect from the introduction of the invention in the extraction of gold and rare etallov in permafrost regions can fix 200-300 thousand rubles a year. Claim 1. Heat pipe, containing the main and auxiliary evaporation and condensation zones and the transport zone, so that, in order to increase the ultimate heat load, the lower part of the transport zone is connected via a pipeline to the auxiliary zone. evaporation, separated from the auxiliary zone of the condensate capillary by a p-porous membrane. 2. Trumpet pop. 1Distinguished that the pipeline is at the connection point f. the transport zone is provided with a nozzle. Sources of information taken into account in the examination: 1.
