ADAPTER Russian patent published in 2010 - IPC F28D7/10 

FIELD: heating systems.

SUBSTANCE: invention can be used as device for arranging hydraulic liquid heating scheme on both sides in high heat stressed heat exchanger working in variable load mode. In adapter rigidly attached to pipes and forming tube-in-tube type heat exchange element in the form of axial sleeve with central hole and two diametrical pairs of channels, central hole is divided as to height into two independent zones, to each of which there connected at an angle to hole axis are channels of one of the pairs; at that, channels of one pair are made with inclination of opposite direction relative to channels of the other pair.

EFFECT: design of the proposed adapter allows obtaining high heat stressed heat exchanger of small sizes.
