HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/02 

FIELD: heating.

SUBSTANCE: in heat exchanger containing the housing with two coaxially located connection pipes, and at that, the latter together with the housing have transient sections in the form of diffusers, to each of which there attached is connection pipe connected to heat exchange tube bank, streamlined displacer is located axisymmetrically to the housing cavity and attached by means of cantilevers to the housing, and heat exchange tube bank connected by means of T-pieces to connection pipes is arranged in the housing in the form of twisted layers of tubes of streamlined displacer and equally spaced as per coils and layer-by-layer by means of planks attached to cantilevers.

EFFECT: design with proposed arrangement of tube bank will allow producing small-size heat exchanger meeting reliability, processibility, erection requirements at high specific heat stresses of the occupied volume of nuclear power plant.
