Abstract

A metal strip is used for elements in a regenerative heat exchanger employed for the exchange of latent and sensible heat from a warm outgoing air stream to a cold ingoing air stream. The strip is placed alternatingly in the form of flat and corrugated sheets to form flow channels for the warm and cold air. The metal strip, for example, an aluminum foil, is coated or laminated at least on one side with a paper-like hydrophillic material. The hydrophillic layer comprises a mixture of cellulose fibers and fibers with olefin hydrocarbons as basis. Furthermore, fungicides can be added to the mixture.
