COLLAPSIBLE HEAT EXCHANGER FOR WATER-TUBE BOILER Russian patent published in 2025 - IPC F24H1/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used in heat power engineering to produce heat and hot water. Disclosed is a demountable heat exchanger comprising: heat exchanger units 9, 10, 30, 31, comprising steel heat exchange tubes 11 arranged parallel to each other and connected to each other by at least one non-separable transition 17, 28, 29, made with possibility of flow turning heat carrier by 180°, flanges 14 installed at the ends of the extreme pipes of the units, provided with holes 8 for threaded elements 16 and holes 24 for the coolant flow, removable transitions 12 formed by flange and cavity elements, wherein said flange element is metal plate 13 with inlet and outlet holes 25 for heat carrier and holes 23 for threaded elements 16, and said cavity element is made with possibility of connection of inlet and outlet holes 25. Located adjacent heat exchanger units 9, 10, 30, 31 are interconnected by said collapsible transitions 12, wherein flanges 14 of such units 9, 10, 30, 31 are connected to flange elements of detachable adapters 12 by means of threaded elements 16 with possibility of disassembly so that output of one such unit 9, 10, 30, 31 communicates with inlet 25 of detachable adapter 12 , and outlet hole 25 of detachable adapter 12 is communicated with input of another such unit 9, 10, 30, 31.

EFFECT: simplified manufacture, assembly and operation of heat exchanger.
