HEAT EXCHANGER Russian patent published in 2010 - IPC F24F3/14 

FIELD: power industry.

SUBSTANCE: heat exchanger includes separate circulation circuits of differently heated air, in each of which there installed on common shaft are disc centrifugal fans with heat exchange plates on edges, and between them there arranged are Peltier converters; at that, on common shaft with end discs there arranged are collectors of electric power supplied to electrothermal converters; at that, between fan discs and heat exchange plates, at some distance from central axis, equally in a circumferential direction there arranged are sleeves with possibility of forming inter-disc gap and thermal contact with electrothermal converters.

EFFECT: increasing heat exchange coefficient without using cooling liquids, and improving its manufacturability.
