Calculation Method on the Cooling Roller of Waterless Offset Press

In order to control the temperature of the ink, a cooling roller is used to cool down the temperature of the blanket cylinder. The calculation of the heat transfer on cooling roller is divided into two parts: One part is the exchange heat with the air through the cooling roller and the blanket cylinder, the other part is the heat conduction of the cooling roller and the blanket cylinder on the contact area. The heat conduction on the contact area is divided into the thermal conductivity generated by the friction and the heat conduction from blanket to the cooling roller.
