[0002] In modern industrial production, aluminum profiles are widely used in many fields such as construction, transportation, electronics, etc. due to their lightness, corrosion resistance and good plasticity. The traditional aluminum profile production process usually includes smelting, casting, extrusion, cooling and finishing. Among these steps, the cooling process is particularly critical because it directly affects the dimensional stability, mechanical properties and surface quality of the aluminum profile.

[0003] At present, most aluminum profile production lines use the cooling bed cooling method. In this method, the extruded aluminum profile is cooled naturally or forcedly through the cooling bed.
