Abstract
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.
