FIELD: structured sheets for making different type constructions such as heat exchangers, heating pipelines, distributing grids, air conditioner, indirect cooling apparatus, drier with heat regeneration, air cooled graduating tower or evaporation cooler.
SUBSTANCE: sheet includes repeating three-dimensional structure on its both surfaces. Such structure includes large number of cone like dents and indentations arranged around planar central zone. At least one of said dents has flat end. Sheet is made according to condition of packing it with other similar sheets. Packing is realized due to contact of said flat end of one dent of sheet with planar central zone of adjacent sheet and due to restricting between adjacent sheets repeating structure of mutually joined free spaces.
EFFECT: possibility for easily securing sheets one to other, possibility for making different-size heat exchangers.
