<p>The present invention provides a device for use with heat exchangers for the transfer of sensible and/or latent heat between a gaseous and a liquid medium which are caused to flow through respective sets of passages separated by essentially parallel foils provided with prominences, preferably corrugations, the foils that bound the liquid passages having an inlet and an outlet for the liquid that are separated from the gas passages and, preferably, being sealed individually around their peripheries, the device being characterized in that the foils fall together in pairs, thanks to their prominences fitting together,to form narrow liquid passages of substantially uniform width while the gas passages are of considerably greater width; and that the width of the liquid passages is determined by closely-spaced distance elements of small height in proportion to that of the prominences and arranged so as to afford a flow resistance that will promote the distribution of the liquid over the surface area of the liquid passages.</p> |
