FIELD: machine building.
SUBSTANCE: cellular element (1) that has, at least, a casing (2) and cellular structure (3) with multiple channels (4) formed by, at least, one, at least, partially profiled metal layer (5) that forms connection points (6) fixing cellular structure (3), in cross section (8) of which maximum 20% of contact internal points (7) form one connection point (6), note that connection points (6) are at a distance one from the other so that each of them is surrounded by zone without connection (9) equal to other such zones.
EFFECT: increase of thermal-impact resistance, improvement of vibro-acoustical characteristics, much longer lifetime.
