Patent attributes
A packing for heat and/or mass transfer between liquid and gaseous media in counter-flow, in particular for water cooling by air in cooling towers, includes a plurality of film elements contoured by corrugations. The corrugations provide flow passages and the film elements are successively arranged behind each other in the thickness direction forming points of contact. Adjacent film elements are connected to one another at their points of contact and mutually facing large surfaces of adjacent film elements have a fine contouring. The fine contouring includes a ribbing with rib webs and rib grooves running transversely to the flow passages. A rib groove is disposed between two adjacent rib webs. The transitions between successive rib webs and rib grooves are designed such that they are substantially free of radii.
