W12/097-0 A roller 100 for forming heat transfer elements 400 may include a central shaft 110 and a plurality of roller elements 120. The plurality of roller elements 120 may be stacked on the central shaft 110. Each roller element 120 defines an outer periphery 122, 5 which is configured to include a geometrical characteristic 130 thereacross. The stacked roller elements 120, either stacked on the central shaft 110 or stacked without using the central shaft 110, configures the roller 100 with a circumferential surface 150 corresponding to the geometrical characteristic 130 of the stacked roller elements 120, to form the heat transfer elements 400 corresponding to the circumferential surface 150.
