Abstract:
1. A contact body for an evaporation humidifier or material exchanger for humidifying, cooling and/or cleaning of gases, the contact body comprising a plurality of corrugated material layers which adjoin each other and thus form a space lattice structure, wherein a liquid can be passed from the top through the contact body and a gas flow can be passed through in cross flow to the liquid for humidification, cooling and/or cleaning of the gas flow, the material layers each comprising: a film of thermoplastic plastic; material layers being interconnected by at least one of welding, bonding and positive fit; corrugation axes at two longitudinal edges of each material layer comprising a corrugation axis section that runs approximately in an orthogonal direction in relation to the respective longitudinal edge, and the corrugation axes between the corrugation axis sections having regions extending obliquely to the longitudinal edges and running in at least two different directions with at least one change of direction in between, in such a way that in each material layer the corrugation axes change direction at least three times; the corrugation axes in a first oblique region lying at an angle α1 to one longitudinal edge neighboring it, and in a second oblique region, they are lying at an angle α2 to the other longitudinal edge neighboring it; the angles α1 and α2 are between 30° and 60°; and the corrugated material layers each having a maximum corrugation height of 12 mM.
