HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/00 F28F21/00 

FIELD: heating.

SUBSTANCE: heat exchanger includes heat exchange tubes arranged in housing and installed in partitions with segmental cut-outs and in tube sheets equally spaced throughout the length of heat exchange tubes; inlet header used for receiving the first fluid medium flowing through heat exchange tubes and outlet header used for discharging the first fluid medium flowing through exchange tubes. Housing is made with possibility of supplying and discharging the second fluid medium flowing via heat exchange tubes, and heat exchange tubes are rigidly connected to tube sheets; at that, partitions divide inner housing space into cavities interconnected to each other and are installed so that the second fluid medium entering the housing can flow subsequently from one cavity to another one; at that, heat exchange tubes, tube sheets and partitions are made from aluminium alloys with clad coating, and partitions are rigidly connected to heat exchange tubes. Rigid connection of heat exchange tubes to tube sheets and partitions is provided with soldered connection.

EFFECT: improving the construction reliability.
