Abstract

The invention relates to a method and an apparatus for cooling a flexible strip, wherein the strip (1) is brought in contact with at least one rotating cooling roll (2;102;202) for transferring heat from the strip (1) to the wall (2a,102a,202a) of said cooling roll, the cooling roll having an interior space (3;103;203) at a predetermined pressure. According to the invention, the interior space comprising at least one evaporation zone (EZ) containing a cooling medium in a liquid state, wherein the temperature of said liquid cooling medium is substantially the temperature of the liquid/gas phase change of that cooling medium at the predetermined pressure, such that the liquid cooling medium is partially evaporated by the heat received from the strip (1) via the cooling roll wall.
The surface of said interior space comprises a holder for holding the cooling medium in the evaporation zone, wherein said holder comprises porous material or wick, having a capillary function.
