Abstract
A core usable as a rotor in humidity exchangers and heat exchangers is disclosed.The core is comprised of alternate layers of flat and corrugated sheet material so arranged that the corrugations form with the flat layers a plurality of fine channels running substantially parallel to each other and axially to the center of the core. The corrugated layers in the axial direction extend at least at one end face of the core beyond the flat layers and the extending corrugated edges are reinforced. A method and apparatus for forming the core is also disclosed.
Claims6
Rotor or similar core for use in humidity exchangers and/or heat exchangers, comprising a mass or core for the exchange of humidity and/or heat built up of alternate layers of flat and corrugated material so arranged that the corrugations form a large number of fine channels running essentially parallel to one another and to the rotor shaft between two end faces of the rotor, characterized in that the corrugated layers seen in a direction along the axis of the rotor project beyond the flat layers at one or both end faces and are provided with reinforced edge portions.
A core usable in humidity exchangers and heat exchangers comprising a laminate of alternate layers of flat and corrugated strip material, said layers cooperating to define a plurality of fine substantially parallel channels extending transversely through said laminate, said corrugated strip material being wider than said flat strip material and having reinforced edges and said flat strip material having a width no greater than the distance between the inner edges of the reinforced portions of the corrugated strip material.
A core usable as a rotor in humidity exchangers and heat exchangers comprising a helically wound laminate of alternate layers of flat and corrugated strip material, said layers cooperating to define a plurality of substantially parallel channels extending axially from side to side of said core, the corrugated strip at at least one side of said core extending laterally beyond the flat strip and having a reinforced edge portion.
