The invention relates to heat engineering

Teal pipes are known that contain a sealed enclosure with evaporation and condensation zones, condensation connected) and an apron conduit.

UejUj invention - intensification tenloobmena.

This is achieved; By the fact that the inner walls of the housing in the areas of isnaresh and tOdsensytsii are finned with the formation of cell-like cells, and inside the case there is not a J-shell that is wired in the evaporation zone by the continuation of the condensate line, and in the condensation zone by the continuation of the steam line, and 1P1a outer plates. Each fitting in the evaporation zone at the outlet: | 1a jet with reflector of return steam and flow, made in the form of a neck.

FIG. 1 - the described heat pipe is schematically depicted; FIG. 2 evaporation zone, cross section; na |}) I1. 3 - 1: otobrand cell.

Heat pipe contains hermetic

housing 1 with evaporation zones 2 and condensation zones 3, connecting condensate duct 4 and steam line 5. The condensate line is filled with a porous-porous filling 6.

The evaporation zone consists of three parts. The inner part is made in the inner perforated shell 7, an impermeable d / w heat carrier, to which, at the perforation sites, are filled externally filled with a porous filler fitting 8. C; the red part, which is a section of the steam line 5, covers the inner part shell 7 and is separated from the outer zone mesh 9. External, located between housing 1 and mesh 9, is provided with ribs 10 attached to housing 1, forming C1 shaped cells filled with capillary-porous

HcUiojuiH gel 6. The outlet openings of fittings 8 are located in each cell with the greatest possible approximation to the inner surface of the housing 1. Each fitting is an evaporation zone at the exit

it is equipped with a backflow deflector 11, having, for example, a disk shape. The condensation zone also has three parts. The inner part is part of the steam line 5. It is bounded by a perforated shell 12 to which fittings 13 are attached to the perforation points. The middle part is the receiving part of the condensate line 4, covers the inner part shell 12 and is separated from the outer mesh 14. In the outer hollow part Located between the grid 14 and the housing 1, are located attached to the housing of the ribs 15, forming a cell. Outlets of fittings 13 are located in each cell as close as possible to the inner surface of housing 1. The transfer section is covered on the outside of the housing 1 by thermal insulation 16 and separated from the evaporation and condensation zones by partitions 17. The transfer section is filled with thermal insulation 18, which is a thin layer The cover also covers 7 in the evaporation zone. A heat pipe is installed in a cooled (heated) device such

Thus, its evaporation zone is located in the area of heat supply, and the condensation zone is located in the area of its removal. In the established mode, the heat exchange heat carrier in the liquid state - NIN, is pumped through capillary forces through the condensate line 4 towards the evaporation zone and further along the capillaries of the porous filler 8 and the outer part of the evaporation zone is heated to the inner surface of the housing 1 heated heat supplied from an external source The intensity of heating is enhanced by (ip 10 cell-like cells. When contacting with body 1 changes agj) era THAT heat carrier l; from the liquid, it turns into vapor. Steam flow through a layer of porous filler, streamlined reflectors 1J., Rushes it off: with pain, g: resistance to the grid 9. Pass through the last, steam enters the middle part of the evaporation zone and then goes through the steam part of the condensation zone, wherefrom the channels in

Claims (2)

1. A heat pipe containing a hermetic crush with evaporation zones and condensation; ation, connected by condensate and steam trap, is different from the fact that, in order to intensify heat exchange, the inner walls of the casing in the evaporation and condensation zones are scraped to form homogeneous cells, and a perforated shell is placed inside the core, which in the evaporation zone is a continuation of the condensate line, and in the condensation zone is a continuation of the steam line and is provided on the outer surface with nozzles. 2. A pipe according to claim 1, in accordance with claim 1, so that each nozzle in the evaporation zone at the outlet is provided with a reflector of the reverse napoBOixj flow, made in the form of schsk. by fittings 13, it is thrown into hollow cells. In contact with the colder surface of the housing 1 and the fins 15 in the condensation zone, the coolant turns into liquid and in this state penetrates through the openings of the grid 14 into the filling material of the receiving part of the condensate level 4. The edges of the fins 15 touch the grid 14. further circulation process thermal fluid; t with a double change of its state of aggregation proceeds as described. In the proposed heat pipe, as a result of separation of the condensate and steam flows, the counterflow is eliminated almost completely in its entire volume, the liquid is drained from the capillary walls and the dry superheated areas in the filler disappear compared to the known pipe. Due to this, as the calculations show, in the pipe it is possible to increase the rate of supply of liquid heat carrier to the surface and the rate of steam supply to the condenser, which will allow intensive heat exchange by at least 20-15 liters. ta Yu eight FIG. 2 FIG. 3
