PIPE SYSTEM OF A HEAT EXCHANGE APPARATUS Russian patent published in 2022 - IPC F28F9/22 F28F9/13 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering and can be used in steam generators and heat exchangers at nuclear power plants with longitudinal and transverse flow of the liquid metal heat carrier in the inter-tube space. In the pipe system of a heat exchange apparatus, the spacing elements are made in the form of rods, placed whereon are bosses with a preset pitch h by height, located equidistantly from the adjacent heat exchange pipes, in the centre of an equilateral triangle, installed at the vertices whereof are heat exchange pipes, and the ends of the rods of the spacing elements are embedded in pipe boards.

EFFECT: technical result is a reduction in the metal consumption, an increase in the utilisation coefficient of the material of the preforms, the ensured ease of manufacture and assembly, an increase in vibrational strength.
