CONDENSING HEAT EXCHANGER EQUIPPED WITH HEAT EXCHANGING DEVICE Russian patent published in 2020 - IPC F24H1/43 F28D7/02 F28F9/02 F28F9/22 

FIELD: heat exchange.

SUBSTANCE: invention relates to condensation heat exchanger (1), comprising: at least two concentric bundles (5', 5") of tubes from heat-conducting material, inside of which is capable to circulate fluid medium-heat carrier, wherein each bundle (5, 5') of the pipes includes a number of arched pipes (50, 50'); tubes of each bundle (5, 5') are located in parallel planes with gap (53, 53') between two adjacent pipes (50, 50'); one header (6) of heat-conducting material, to which two ends (51, 51', 52, 52') of each tube (50, 50') of different bundles (5, 5') are connected, wherein this collector 6 is equipped with inlet branch pipe (61) and outlet branch pipe (62).

EFFECT: heat exchanger is characterized by that collector (6) includes several partitions limiting various channels, which provide circulation of fluid medium to be heated in various consecutive beams from most external beam to internal beam.
