FIELD: machine building.
SUBSTANCE: absorber comprises a layer of structured attachment fitted by corrugations. The corrugations form a variety of open channels. The channels comprise the first corrugation recess, the first corrugation protrusion and the second corrugation protrusion. The first corrugation protrusion and the second corrugation protrusion confine the first corrugation recess, and the first and the second corrugation protrusions have the first tip and the second tip. An indentation passing in the direction of the first tip is provided on the first tip of the first corrugation protrusion. The first corrugation recess has the recess bottom, and normal distance from at least one indentation point to the corrugation recess bottom is less than the normal distance from the first tip to the corrugation recess bottom.
EFFECT: invention provides for improved mass exchange for absorber or desorber.
