The aluminum extrusion process softens the aluminum rod under the condition of 480 degrees to 530 degrees, and then extrudes through the die under the high pressure condition of the extruder to obtain the processing method of the long aluminum profile with constant cross section.
Disadvantages of aluminum extrusion: material limitations, not suitable for the extrusion of copper radiators with complex cross-sections; the thickness of the teeth must be greater than 0.5, and the ratio of the height and spacing of the teeth must not be greater than 19.
The characteristics of the extruded type determine that the extruded type is suitable for heat dissipation fields with large batches, low power consumption and high product price requirements. Mainly used in ordinary CPU radiator, LED low-power lighting and low-power chip heat dissipation, etc., it is a process choice with good cost performance for mass supply.
Aluminum extruded radiator: Aluminum extruded radiator is a heat dissipation product obtained by cutting, slotting, drilling and tapping, CNC and other processing on the basis of aluminum profile. Aluminum extruded radiators generally use AL6063 material, which has good thermal conductivity (160~180W/㎡·K) and relatively low cost. It can be used as a chassis, not only as a chassis structure but also as a heat dissipation component, or as a motherboard chip. Heat dissipation, stable performance, high cost performance, suitable for mass production.
