A dewpoint cooler comprises: a first air circuit and a second air circuit coupled thereto via a heat-conducting wall, through which two circuits can flow two media, wherein the second medium contains a gas, heat-conducting wall break-up means for breaking up at least the thermal boundary layer ( 50 ), the laminar boundary layer and the relative humidity boundary layer in both media, which break-up means comprise heat-conducting protrusions; wherein the surfaces of said wall and the break-up means are covered with a hydrophilic coating, which can absorb an evaporable liquid, retain it and relinquish it again ( 100 ), such that the wetted coating, the heat-conducting surfaces and the break-up means are cooled. A wetting ( 150 ) unit for subjecting the secondary medium to wetting by the evaporable liquid such that evaporated liquid entrained by the secondary medium extracts heat from the primary medium via the wall. |
