SURFACE CONDENSER Russian patent published in 2011 - IPC F28D5/02 F28B3/02 F28B9/00 F28F9/00 

FIELD: machine building.

SUBSTANCE: surface condenser for differential fluidisation of vapour components of mixed flow consists of at least two successively connected heat exchangers jointed to each other without end covers and tube bridges with their tubular grids so, that tubes of each preceding heat exchanger downstream mixed flow are elongated beyond outlet enclosure. Their diametre is less, than diametre of tubes of the next heat exchanger and are inserted inside of them forming a gap to drain condensed component. A cavity and channel for withdrawal of drained component are made in the outlet enclosure of the preceding heat exchanger or in an inlet enclosure of the next heat exchanger.

EFFECT: reduced metal consumption of condenser and reduced hydraulic resistance along circuit of volatile components motion due to connection of heat exchangers.
