HEAT EXCHANGE UNIT Russian patent published in 2010 - IPC F24D3/00 F28D15/00 

FIELD: power industry.

SUBSTANCE: heat exchange unit includes at least two groups of channels for movement of waste energy heat carriers and for waste energy heat consumers with various operating ranges of initial and final boundary parametres for waste energy and for heat carriers of waste energy consumers. Unit also includes heat exchangers mounted in each channel and connected via circulation circuit of intermediate heat carrier to agitator. Heat exchangers in each channel consist of the sections the number of which is determined with gaps between boundary parametres of heat carriers, which are neighbouring as to the value, in operating ranges of initial and final parametres of heat carrier of the appropriate channel. Inlets and outlets of intermediate heat carrier of all sections within each gap are connected in addition with connection straps. On one of the connection straps there can be installed auxiliary movement agitator of intermediate heat carrier. The unit operates in certain manner with partial bypass of intermediate heat carrier along connection straps.

EFFECT: increasing heat transfer efficiency and its use.
