HEAT EXCHANGER Russian patent published in 2013 - IPC F28D3/00 

FIELD: heating.

SUBSTANCE: heat exchanger includes a heat exchange surface, a device for supply of heat carrier with holes; at that, heat exchange surface includes a divergent branch pipe of supply of heating heat carrier and a tubular grid, between which a thermoelectric generator made in the form of a housing with a pass for heating heat carrier and a set of differential thermocouples is located; at that, the inlet of the pass for heating heat carrier is connected to the inlet of the divergent branch pipe for supply of heating heat carrier of heat exchange surface, and its outlet is connected to the outlet of the divergent branch pipe for supply of heating heat carrier before the tubular grid; besides, hot ends of the set of differential thermocouples of the thermoelectric generator are located inside the pass for heating heat carrier, and their cold ends are fixed on the surface of the housing of the thermoelectric generator far from the pass for heating heat carrier.

EFFECT: reduction of power consumption at continuous operation of heat exchanger, especially at night time.
