SHELL-AND-TUBE HEAT EXCHANGER Russian patent published in 2013 - IPC F28D7/16 F28F9/22 

FIELD: power industry.

SUBSTANCE: in a shell-and-tube heat exchanger containing identical sections connected to each other, each of which includes a bank of tubes, which is arranged in the shell, at that, the tubes are fixed on opposite ends in tube sheets, and header chambers of tube and inter-tube media with partition walls forming spatial connections between sections and specifying medium flow directions in them, header chambers of the tube and inter-tube media includes the sections, in which partition walls are installed after two or more inlets of media to the sections, thus forming series connected groups of two and more sections with parallel medium flow in each group; at that, in the header chamber of the tube medium there can be installed an additional partition wall before medium inlets to the sections of one of the groups with parallel medium flow.

EFFECT: improving use efficiency of heat energy of a primary source owing to reducing hydraulic losses.
