What causes tower after cutting aluminum coilInsulation aluminum coil will appear when the cooling bending phenomenon, reason is generally under the conditions of air cooling, the heat transfer coefficient of the aluminum coil insulation parts in contact with the air were flat, but because the wall thickness or different shapes, different parts of the heat dissipation rate is not balanced, resulting in thick wall or hollow tube heat faster than the thin Department of slow, resulting in insulating aluminum roll cooling occurs to the hollow part.Insulation aluminum coil will appear when the cooling bending phenomenon, reason is generally under the conditions of air cooling, the heat transfer coefficient of the aluminum coil insulation parts in contact with the air were flat, but because the wall thickness or different shapes, different parts of the heat dissipation rate is not balanced, resulting in thick wall or hollow tube heat faster than the thin Department of slow, resulting in insulating aluminum roll cooling occurs to the hollow part.Insulation aluminum coil will appear when the cooling bending phenomenon, reason is generally under the conditions of air cooling, the heat transfer coefficient of the aluminum coil insulation parts in contact with the air were flat, but because the wall thickness or different shapes, different parts of the heat dissipation rate is not balanced, resulting in thick wall or hollow tube heat faster than the thin Department of slow, resulting in insulating aluminum roll cooling occurs to the hollow part.Other related question
