The invention relates to the field of heat, and more particularly to a heat pipe, namely the gravitational heat pipes used mainly by freezing the ground to strengthen the foundations and basements of various buildings constructed on permafrost.
The known gravitational heat pipes containing a pressurized partially filled with fluid body with zones of evaporation, condensation and transport area (see, for example, the patent of the Russian Federation for invention №2327940, publ. 27.06.2008 ; Russian Federation patent for useful model №68108, publ. 10.11.2007 ).
The known gravitational heat pipes have a hard shell and, therefore, a fixed geometric shape. In particular, the pipe under the patent  is straight, and the pipe under the patent  bent at an angle close to direct.
When increasing the length of these pipes appear difficult technological problems in production (because you need the extended premises), and during transportation of the pipes and their installation in vertical wells. In addition, difficulties arise when laying the evaporation zone at the construction site, for example, between the existing pile Foundation. You should take into account that carrying out a welding, check welds for leaks, and also prohibited the internals of the pipe carrier in the Far North it is difficult and expensive. Therefore, the pipe shall be manufactured in good manufacturing conditions and delivered to the place of their operation in the ready to install and use.
The invention is directed to the achievement of the technical result consists in ensuring the efficiency of production, transportation and installation of the gravitational heat pipes into position on the object to use.
Closest to the present invention is the gravitational heat pipe according to the patent .
The proposed gravitational heat pipe, as specified closest to it is known, comprises a sealed partially filled with liquid coolant housing with zones of evaporation, condensation and transport area.
To achieve the technical result in the proposed thermal gravity pipe, unlike most similar known building in the area of evaporation and transport area or in any one of these zones has at least one insert made in the form of a bellows connected to the hull sections between which it is located, cylindrical tips. The bellows is enclosed in an elastic metal stocking, the ends of which are secured to these lugs. In addition, the insert is equipped with a rigid removable clip for fixing the relative position of the sections is of ARPUs, between which is inset. Rigid removable clip made with the possibility of accommodation around the specified stocking and attaching it to adjacent to the inserting sections of the hull.
Due to the presence of inserts in the form of a bellows installed in these more extensive areas of the body, and by doing hard clips removable proposed heat pipe during transportation can be folded, for example, in the form of the snake. This bellows mentioned inserts bent 180 degrees and located between the inserts section of the housing is placed in the container parallel to each other. Therefore, the size of the container and the vehicle length can be several times less than the total length of the heat pipe. When manufacturing a heat pipe, with the proposed design, do not need to be in one line all the sections of the casing, between which are inserted in the form of bellows, thereby avoiding the need for extensive industrial premises.
Elastic metal stocking, which concluded the bellows, it provides mechanical protection, without which it is impossible neither the transportation nor the operation of the heat pipe in the actual conditions for which it is intended.
Rigid removable clips that are in the process of transporting of the heat pipe in a removed state is AI, when installing pipe in the working position are attached to the hull sections and provide, depending on what is required in specific circumstances, straightness or fixed angle bend centerline of the hull sections and bellows mounted between them.
Marked features combine to provide the best technology of production, transportation and installation of the proposed heat pipe into position on the object of use. Obviously, the ability to achieve the technical result exists when placing at least one insert in any one of these areas of the body, which is the longest, but preferably multiple inserts as in the evaporation zone, transport zone.
Rigid removable clip, designed for insertion within the area of evaporation, may be perforated. In this case, it can be done, for example, in the form of rods mounted with clearance relative to each other and fixed by their ends to adjacent to the insertion sections of the body in connection with insert.
The presence of perforation, including the described implementation of the hard casing in the form of rods, provides the ability to fill the space between it and the grip surrounding the bellows, soil or sand for which menichini thermal resistance to heat transfer to the bellows.
The invention is illustrated in the drawings:
- figure 1 shows a rectilinear gravitational heat pipe with inserts in the form of a bellows in the evaporation zone and in the transport zone (position "a"), only in the evaporation zone (position "b") and only in the transport zone (position "b");
- figure 2 presents a curved gravitational heat pipe with multiple inserts in the form of a bellows in the evaporation zone, located in the working position at a small angle to the horizon;
- figure 3 is given a longitudinal section a-a heat pipe of figure 1 in the paste area in the form of a bellows;
- figure 4 presents the cross-section b-B of the insert, shown in figure 3;
- figure 5 shows the proposed gravitational heat pipe, folded in a "snake" for transportation.
The proposed gravitational heat pipe comprises a sealed enclosure 1 (figure 1, 2) evaporation zones 2, condensation of 3 and transportation area 4. The casing is partially filled with liquid coolant 5. In the evaporation zone 2 (figb, figure 2) or in the transport zone 3 (pigv) or in both of these areas (figa) the pipe has a box 6 (see also figure 5). Box 6 contains (see figure 3) flexible element in the form of bellows 9 with a cylindrical lugs 10. Through the last bellows 9 is connected to the adjacent sections of the housing 1. The bellows 9 is enclosed in a metal braided stocking 11, the ends of which vtorogo attached to the lugs 10. Around the flexible element in the form of bellows 9 to stocking 11 posted by hard ferrule 8. The yoke 8 is made removable. For this purpose, it may, for example, consist of shown in figure 4 the two half-rings 12, which are welded with their ends the rods 13. Specified parts of a holder with screw connection 14 are mounted on the body at the joints of its sections with cylindrical ends of the bellows.
The location of the rods 13 with a gap relative to each other can provide a perforation. The latter is useful when inserting a bellows 9 is installed in the evaporation zone. Clearances allow you to fill the space between the grip 11 and the rod 13 soil or sand to reduce thermal resistance to heat transfer from the earth to the bellows.
In the process of manufacturing heat pipe ferrule covering the flexible element insert 6 (bellows 9 enclosed in stocking 11), is not installed. During the transportation of the heat pipe is folded in a "snake" condition (figure 5). This section of the housing 1 are stacked parallel to each other by bending inserts 6 at an angle of 180 degrees. Before on-site installation of the heat pipe straighten around inserts 6 install the clip 8, which provide finding the axes of the sections of the casing and bellows on one line (as in figure 1) or provide a fixed bending the longitudinal axis of the housing (to the extreme left clip 6 in figure 2). In the latter case, if the magazine is made in accordance with figure 4, the rods 13 must have the necessary bending. Clip 8 perform their function in the process of construction works and operation of the facility.
In a vertical well immersion of the proposed heat pipe is produced for each section. After immersion of the first section of the housing vertically mounted in the second section, fixed clip, immerse second section, etc. eliminating the need for bulky hoisting-and-transport devices.
If part of the body with the condensation zone or heavy should be located high above the ground level, first in the working position set on the object part of the body with the evaporation area and transport area. When this part of the body with the condensation zone due to the flexible element insertion located in the transport zone is in the folded state. Then the part of the body with the condensation zone raise up, straighten the flexible element of this paste, after which it impose a cage.
The operation of the proposed gravitational heat pipe is traditional for such pipes. It is the movement of steam up due to the differential pressure of saturated steam in the areas of evaporation and condensation, and reverse motion of the fluid is p is D. the force of gravity. The heat pipe transfers heat Q (1, 2), absorbed by the coolant and given to them by condensation in the external environment.
The advantages of the proposed gravity pipe before known is that it is easier to produce, transport and install on site. During transportation of the pipe can be folded in the usual size of trailers and railway wagons "snake", as shown in figure 5. Here is the section of the body 1 placed parallel to each other by bending inserts 6 at an angle of 180 degrees. In the same way can be located sections of the hull to connect them with inserts in the manufacture of pipe and test it for leaks. In addition, the advantage is a more cheap way of immersing the tube in a vertical borehole, as in this case does not require cumbersome handling equipment, delivery of which the objects of the Far North, in some cases, simply impossible. The object of this pipe can be laid in a curve around obstacles, for example, already crammed into the soil pile.

In case of further increase of generated energy, temperature in said zones is increased to high limits at equality of energies. Then, in the course of change of generated energy, temperature correction cycles in temperature control zones are repeated.
EFFECT: avoidance of excess of consumed energy above generated energy of solar batteries.
