FIELD: process engineering.
SUBSTANCE: invention covers the method of producing cellular element 6 with radial annular part 9 with flow passages 10, made up of, at least, one metal layer (1, 13, 14). Said metal layer is secured in, at least, one point 16, to outer tubular casing (7). Every said metal layer (1, 13, 14) has sections (2, 3) superimposed by layer accordion folding. Note here that said metal layer features alternating, mainly, flat 2 and shaped 3 sections. Besides, invention covers cellular element (6) with radial annular section (9) with flow passages (10) made up of, at least, one metal layer (1, 13, 14), which in, at least, one attachment point (16) is secured to outer tubular casing (7), wherein each metal layer (1, 13, 14) has section (2, 3) superimposed by metal layer accordion folding. Note here that metal layer features alternating, mainly, flat (2) and shaped (3) sections.
EFFECT: low material input, longer life.
