MATRIX OF RING-SHAPED LAMELLAR HEAT EXCHANGER Russian patent published in 2006 - IPC F28D9/02 

FIELD: gas turbine construction.

SUBSTANCE: matrix can be used in heat exchangers of heat regeneration heat system's exchanger, as well as for warming up (cooling down) gas or liquid in different heat-sing installations. Matrix of ring-shaped lamellar heat exchanger has heat-exchange members formed by lamellar plates with corrugated parts and openings of collectors, which are connected by means of lugs of internal and external diameters of plates or by means of lugs of collectors. Corrugated parts and collectors are limited by internal and external diameters of ring-shaped plate, or by lines being equidistant to them, and by frontal planes being parallel to axis of symmetry of corrugated parts. Axes of symmetry of any part and of collectors pass through center of plate. Angles between frontal planes of distributing and gathering collectors are equal to each other. Vertexes of angles are disposed at concentric circles having the same or different radiuses. Area of distributing collector relates to gathering collector is directly proportional to relation of corresponding radiuses of vertexes of angles and belongs to 0,4-0,8 interval.

EFFECT: improved efficiency of operation of heat exchanger.
