Abstract
A cooling roller of a cooling machine for continuously and quickly cooling a high temperature sheet. The cooling roller comprises a rotary shaft, and a cylindrical outer wall and end walls mounted on the shaft and forming an enclosure are mounted on the shaft. A tube bundle extends through the enclosure close to the outer wall, the tube bundle having an inlet and an outlet for a cooling fluid. The heat transfer area of the tube bundle is larger than the inner area of said outer wall, and the inner area of the outer wall is covered with a heat transfer accelerating device. A heat transfer liquid, which repeats evaporation and condensation cycles during use is sealed within the enclosure.
