Description

one

The invention relates to heat engineering equipment.

Known adjustable heat pipes, which contain a housing with a capillary structure inside, which has a conveying condensation zone, the latter of which is connected to the gas reservoir, do not increase the efficiency of heat transfer and increase the control accuracy.

The purpose of the invention is to increase the heat transfer efficiency by increasing the control accuracy.

This is achieved by the fact that the condensation zone is made in the form of parallel branches united by a common collector from the transport zone side, each of which is connected to a gas reservoir; The evaporation area on the outside has sockets for connecting a heat source, for example, in the form of autonomous heat pipes; the condensation zone together with the gas reservoir is placed in a compartment filled with a heated medium.

FIG. 1 shows the scheme of the proposed adjustable heat pipe; in fig. 2-Section A-A in FIG. one.

The adjustable heat pipe includes a housing 1 with an evaporation zone 2, a transport zone 3 and a condensation zone 4. Inside the housing has a capillary structure 5. Condensation zone 4 is made in the form of parallel branches 6, which are connected by a common collector 7, and on the other side each branch is connected with a gas reservoir 8 through channels 9. The evaporation zone 2 on the outer side has slots 10 for connecting a heat source, for example, in the form of autonomous heat pipes 11,

flat or round. The gas tank 8 with the condensation zone 4 is placed in the compartment 12, filled with a heated medium, naprnmer, gas mixture.

Adjustable heat pipe works as follows.

The working fluid enters through a capillary force through a capillary-loric structure of parallel branches 6, a collector 7, a transport zone 3 to the evaporation zone 2,

form a thin layer of working fluid. When the heat pipes 11 are heated in the evaporation zone 2, the working fluid is heated and evaporated from the canyls of the pR-5 structure 5. The working fluid vapor flows from the evaporation zone 2 through the transfer zone 3 to the condensation zone.

When the heat flux to the heat pipes 11 decreases, the evaporation of the working fluid into the evaporation zone accordingly decreases and the amount of steam decreases throughout

the system, and the gas from the gas tank 8 through the channels 9 enters the parallel zetwies 6 of the condensation zone 4, thereby turning off part of the heat exchange surface. Otherwise, it works in the evaporation direction, which can lead to heat outflow from the compartment 12.
