The invention relates to devices for the transfer of heat between two media and can be used in the chemical, metallurgical and other industries, agriculture for utilizing low-grade heat, air conditioning of industrial premises, etc. A heat exchanger is known, comprising a housing and a drum rotating in the housing in the form of a thermal beam. Tpy6 A disadvantage of the heat exchanger is its low reliability. A heat exchanger is known which comprises a shell, divided by means of a flat disk mounted on a rotating shaft on hot and cold gas cavities, and heat pipes with evaporation, transport and condensation zones fixed on the disk parallel to shaft C23. The disadvantages of the known heat exchanger are low intensity of heat exchange and low reliability. J. The purpose of the invention is to intensify heat transfer and increase reliability. The goal is achieved by the fact that in a heat exchanger containing a casing separated by means of a flat disk mounted on a rotating shaft on a cavity of hot and cold gases, and heat pipes with evaporation, transport and condensation zones fixed on the disk parallel to the shaft, the evaporation zone of each heat pipe offset from its condensation zone to the periphery of the disk by more than the pipe diameter, and the transport zone is inclined, with each heat pipe in the evaporation and transport zones provided with an insert in the form of ASTINA situated in the zone of evaporation with a clearance with respect to its wall and having a hole transport zone with shoulders. Moreover, the shaft can be pasted lo. 1 shows a heat exchanger with a transverse gas supply in FIG. 2 — a heat pipe, a longitudinal section 5 in FIG. 3 — section AA — in FIG. 2, figure 4 — section BB in FIG. 2; figure 5 - heat exchanger with radial flow of gases, the cut; figure 6 - section bb In fig.Z. The heat exchanger contains a cold gas cavity 1, a hot gas cavity 2, separated by a seal 3 and a flat disk 4, located on a rotating shaft 5 mounted in bearings 6, and on a disk 4 parallel to the axis of rotation heat pipes 7 are installed, with condensation zones 8 and evaporation 9 and 10 bend between them. In the evaporation zone 9, the insert 11 is installed along the entire length, which forms a gap 12 with its side surface, in the place of the bend 10 of the heat pipe 7, the hole 13 is executed in the insert with the shoulders 14 facing the condensation zone 8. On the side surface of the evaporation zone 9, screw cutting 13 is made. Between the heat pipes 7. blades 14 are installed. Heat pipes 7 are partially filled with coolant 15. The heat exchanger works as follows. The hot gas through the surface of the heat pipe 7 in the evaporation zone 9 releases heat to the intermediate heat carrier 15, which evaporates. The vapor from the evaporation zone 9 through the opening 13 moves to the condensation zone 8, where, condensing, is given away. emits heat through the wall of the heat pipe 7 to the cold gas. The liquid formed by the action of centrifugal forces flows into the part of the condensation zone 8 remote from the axis of rotation and flows in the form of a stream; evaporation zone 9. At the site of the bend 10 of the heat pipe 7, the heat transfer fluid 15 flows onto the insert 11 and flows along it along the evaporation zone 9, irrigating its entire side surface through the gaps 12. The shoulder 14 around the opening 13 in the insert 11 do not allow the heat carrier 15 to move to the evaporation zone 9 through the opening 13. Screw cutting 12 on the surface of the evaporation zone 9 increases the efficiency of heat transfer during the evaporation of the heat transfer fluid. The working gases can flow into the heat exchanger from external fans or between the heat pipes 7 can be located blades 14, which, when the rotor rotates, will move the gases. To prevent the heat-exchanging gases from flowing from one cavity to another, a seal 3 is installed, which can.

It can be implemented in the form of a maze of its pump and ensure a small flow of gas from the truck, that of pure gas into the tract with the waste ha-1 zones.
