HEAT EXCHANGE DEVICE Russian patent published in 2013 - IPC F28D7/10 

FIELD: power engineering.

SUBSTANCE: heat exchange device comprises a heat exchanger with a body and a cylindrical shell, forming channels, input and output headers, an additional heat exchanger, arranged in series with the first one, comprising input and output headers. Besides, inside heat exchangers there is a tubular heat exchanger, comprising input and output headers, arranged between two first heat exchangers, besides, the tubular heat exchanger has uniting input and output headers, connected by pipelines to each other and to input and output headers, besides, inside the tubular heat exchanger there is a cylindrical screen with a fairing, and the output uniting header is connected with the body of the first heat exchanger by pylons, arranged at the angle a to the axis of the heat exchange device. The tubular heat exchanger also comprises a band installed between the uniting headers, and the additional heat exchanger is equipped with a nozzle.

EFFECT: invention makes it possible to increase efficiency of a heat exchange device without increasing its dimensions.
