HEAT EXCHANGER Russian patent published in 2009 - IPC F28F27/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering, particularly to heat exchangers and can be used in heat exchanging or heat-transmitting devices. Heat exchanger with case, which allows primary inlet connection, primary exhaust connection, repeated inlet connection and repeated exhaust connection, between primary inlet connection and primary exhaust connection it is located primary flow path of primary side, and between repeated inlet connection and repeated exhaust connection it is located repeated flow path of repeated side, herewith primary flow path is in condition of heat exchange with repeated flow path.

EFFECT: improvement of heat exchanger parametres, achieved ensured by auxiliary control unit passes through the intermediate space, located between primary flow path and in repeated flow path.
