A device (1) for cooling an airflow (A1) is disclosed. The device (1) comprises at least one cooling channel (2) with an inflow opening and an outflow opening. At least one evaporating channel (3) is separated from the cooling channel by a transfer wall (4) and has an inflow opening, which is connected to the outflow opening of the cooling channel (2), and an outflow opening. A means for wetting the side of the transfer wall (4), such as a water spray, is directed toward the evaporating channel (3). In order to increase the efficiency of the device a means for dehumidifying the airflow in the cooling channel (2) is also provided. This increases the evaporation in the evaporation channel (3) and therefore the cooling effect of that evaporation. The dehumidifier is a polymer with lower critical solution temperature (LCST). The side (15) of the transfer wall (4) directed toward the cooling channel (2) can be covered the polymer or the transfer wall (4) may be manufactured from it. The cooling device (1) can also have means for regenerating the dehumidifier by removing absorbed moisture. This could be in the form of a heating element (17) as part of the cooling channel (2).
