HEAT-PIPE INJECTION SCREW Russian patent published in 2014 - IPC F01K17/00 

FIELD: heating.

SUBSTANCE: invention relates to heat engineering and can be used for utilisation of secondary energy resources and low-potential energy of natural sources. The technical result is achieved in heat-pipe injection screw that includes evaporation, working and condensation chambers located in one cylindrical housing, the inner surfaces of upper and lower end walls of which contact a wick passing along a central axis of the housing, which is covered with a shell so that gaps at upper and lower end walls are formed. In evaporation and condensation chambers there located are guide plates connected to the working chamber; between the housing and the evaporation and condensation chambers there are annular gaps forming hot and cold annular jackets with outlet openings. The inner surface of end and side walls of evaporation and condensation chambers is covered with a grid made of thin strips from porous material. The working chamber is provided with a screw groove on the outer surface and connected to evaporation and condensation chambers through annular seals; its external housing is equipped with suction and discharge branch pipes.

EFFECT: improving efficiency of a heat-pipe injection screw.
