Apparatus for indirect, evaporative cooling of an useful air current, including a contact body (10) made up in layers, with duct systems between the layers. There are two separate duct systems, useful air for cooling passing through one system (16), while a cooling air current passes through the other system (18). Cooling takes place by evaporation of water in the other duct system (18). The duct-forming means (16, 18) in both systems are disposed such that the useful and cooling air currents flow horizontally, while water supply means (24) supplying water to the other duct system (18) are disposed at the top of the contact body (10), allowing the water to flow vertically downwards in this system (18). |
