CONDENSER EVAPORATING PIPE Russian patent published in 2018 - IPC F28D3/02 B01D47/05 

FIELD: manufacturing technology.

SUBSTANCE: condenser-evaporation tube is proposed, in the inner part of which vapor flows, which is subjected to condensation and through which liquid flows, which is subjected to evaporation, and an inner, and outer surfaces of this tube are covered with capillary structures made to form liquid concave-convex lens having a contact angle less than 90°, liquid-vapor interface is curved to provide capillary condensation inside the pipe and evaporation on the outer surface at upper end (25) of concave-convex lens of liquid, where layer of liquid is the thinnest, and evaporation is the most effective.

EFFECT: increasing of heat efficiency of the pipe.

13 cl, 15 dwg
