HEAT-TRANSFERRING DEVICE Russian patent published in 2006 - IPC F28D15/02 

FIELD: applicable for heat abstraction in various media.

SUBSTANCE: the heat transferring device has a sealed pipe with condensation and evaporation zones filled up with a heat-transfer agent with pockets provided on the inner surface, the pockets used for inhibition of draining condensate are located in the evaporation zone and made annular or formed by the sections of the helical surface adjoining the pipe inner wall with its lower edge at an acute angle, which are separated from one another by radial partitions, the annular pocket is formed by the side surface of the truncated cone, adjoining the inner wall of the mentioned pipe with the larger base. Besides, at least some of the pockets located one above other are positioned at such a distance that a capillary effect occurs between the surfaces facing one the other.

EFFECT: enhanced efficiency of heat transfer due to the increase of the pipe surface wettable by the heat-transfer agent, as well as simplified structure an facilitated actuation of the device.
