ADAPTER Russian patent published in 2010 - IPC F28D7/10 

FIELD: heating systems.

SUBSTANCE: invention can be used as device for arranging hydraulic diagram of liquid heating on both sides in high heat-stressed heat exchanger operating in variable load mode. In adapter rigidly connected to tubes and comprising a tube-in-tube heat exchange element in the form of axial sleeve with central hole divided as to height into two independent zones to each of which channels of one of the pairs are connected at an angle to hole axis, channels of one pair are made with inclination of opposite direction relative to channels of the other pair; at that, cross-section area of channels increases as it moves from central hole.

EFFECT: design of the proposed adapter type allows producing high heat-stressed heat exchanger of small sizes and decreasing hydraulic resistance at inlet and outlet of heat exchange liquids.
