A device for use with heat exchangers for the transfer of sensible and latent heat between a gaseous and liquid medium is provided. The device includes a first set of narrower passageways defined between at least two corrugated foils to receive the liquid medium, and a second set of wider passageways to receive the gaseous medium. The surfaces of the foils defining the narrow liquid passageways have closely spaced fine ridges which cross the corrugations. These fine ridges cause flow resistance and result in the liquid medium in the liquid passageways being distributed over the entire surface area of the foils defining the liquid passageways, thus enhancing heat transfer. Furthermore, because the ridges tend to rigidify the foils defining the liquid passageways, these foils can be formed from a relatively thin material, thus further enhancing heat transfer between the liquid and the gas mediums. |
