Abstract

Invention m. used in cooling systems of internal combustion engines. The purpose of the invention is to provide heat exchange between liquid and gaseous media and to intensify heat exchange. The evaporation zones of all heat pipes (TT) 7 are combined and made in the form of a single hollow disk 10 with a lateral surface of a triangular profile located outside the transverse dimension of the impeller and provided outside with guide vanes that form a liquid pump. On the inner surface of the disk 10, facing the zones of condensate TT 7, there are annular and radial channels. Separate transportation of flows and tightness of the liquid path is provided by the separation wall 2 with seals 3. When the impeller rotates, the heated medium is transported through channel 4, and the heating fluid is transported through channel 5. Due to the temperature difference between the heating liquid and heated air, the heat carrier evaporates the conical part of the hollow disk 10, and the vapors formed are condensed in the condensation zone of the TT 7 and returned to the side of the disk as condensate 10. 1 z.p. f-ly, 4 ill. -i (lv ate from to

Description

I The invention relates to heat transfer to other apparatuses and can be used in cooling systems for internal combustion ventilators, heating, ventilation and air conditioning systems;

The purpose of the invention is to ensure TF-exchange between liquid and gas environments and the intensification of heat exchange.

FIG. 1 depicts a regenerative heat exchanger; in FIG. 2, times A-A in FIG. 1, FIG. 3 — section BB, in FIG. 2, in FIG. 4 — node I in

.

Regenerative heat exchanger comprises casing 1, in which the regulations

 on the separating wall 2 with the optic 3, forming the channels 4 and S, respectively, for the heated immersion and heating liquid media, the impeller 6. The impeller 6 includes profiled blades formed by heat pipes 7, the partition 9 and the hollow disk 10, which unites the evaporation zones of all heat pipes 7. The side of the hollow disk 10 has a triangular profile that is located outside the transverse envelope of the impeller 6 and is provided outside pump. I On the inner surface of the disk IIG, facing the condensation zones of heat pipes 7, annular 12 and radial 13 channels can be made. Drive is through

pulley 14.

Regenerative heat exchanger works as follows.

When the impeller 6 rotates through the belt drive and the pulley 14, the heated medium is captured by the guide vanes 8 and the core blades from the heat pipes 7 and transported through the channel 4 of the housing 1 according to the principle of a diametrical fan. At the same time, the heating fluid is captured at 0

pilot blades 11 and transported through channel 5 according to the principle of a vortex pump. Separate transportation of streams and tightness of the liquid path is provided by the separation wall 2 with seals 3. Due to the temperature difference between the heating liquid and heated air, the heat carrier in the conical part of the hollow disk 10 evaporates. The guide blades 11 additionally act as fins, and The conical part improves the vapor release to the surface of the liquid phase. The resulting coolant vapors are transferred through the channels of the profile blades to the condensation zones of the heat pipe 7, washed by an air medium having a lower temperature. The condensed coolant moves along the channels of the profile blades in the direction of the evaporator, made in the form of a hollow disk 10, through the annular 12 and radial 13 channels and flows into the side of the disk 10 without interfering with the movement of the coolant vapors and not catching them.
