COUNTER-FLOW PLATE-TYPE MATRIX-ANNULAR COMPACT CERAMIC RECUPERATOR Russian patent published in 2012 - IPC F28D9/00 

FIELD: machine building.

SUBSTANCE: counter-flow plate-type ceramic matrix-annular compact recuperator is made in the form of a row of cylindrical heat exchange matrixes of equal width and of various diameters. Matrixes are installed coaxially one inside the other and assembled in the form of a pile of flat annular plates with central holes and peripheral semi-holes between them. As a result there formed is system of longitudinal channels in which separate flows of heated and heating heat carriers move in opposite directions. In cross connections between central holes there made are transverse slot holes forming an annular transverse toroid-shaped channel.

EFFECT: recuperator design allows its effective use in cases when mass flow rates of heat carriers differ by several times.
