The invention relates to a device for cooling an airflow, comprising at least one cooling channel with an inflow opening for the airflow for cooling and an outflow opening for the cooled airflow, at least one evaporating channel separated from the cooling channel by a transfer wall and having an inflow opening, which is connected to the outflow opening of the cooling channel, and an outflow opening, means for wetting the side of the transfer wall directed toward the evaporating channel, and means for dehumidifying the airflow in the cooling channel. The dehumidifying means can comprise a polymer with lower critical solution temperature (LCST polymer) with which the side of the transfer wall directed toward the cooling channel can be covered or from which it can be manufactured. The cooling device can further have means for regenerating the dehumidifying means.
L~invention concerne un dispositif de refroidissement d~un flux d~air, comprenant au moins un canal de refroidissement doté d~une ouverture d~entrée du flux d~air à refroidir et d~une ouverture de sortie du flux d~air refroidi ; au moins un canal d~évaporation isolé du canal de refroidissement par une paroi de transfert et doté d~une ouverture d~entrée, raccordée à l~ouverture de sortie du canal de refroidissement, et d~une ouverture de sortie ; des moyens d~humidification du côté de la paroi de transfert situé en regard du canal d~évaporation ; et des moyens de déshumidification du flux d~air circulant dans le canal de refroidissement. Les moyens de déshumidification peuvent comprendre un polymère à température critique inférieure de démixtion (polymère LCST) susceptible de recouvrir ou de constituer le côté de la paroi de transfert situé en regard du canal de refroidissement. Le dispositif de refroidissement peut comporter en outre des moyens de régénération des moyens de déshumidification.
