Aluminum profile radiator, also known as radiator aluminum profile, has the characteristics of beautiful appearance, light weight, good heat dissipation performance, and good energy-saving effect. The surface of the processed aluminum radiator is treated with anodizing to increase its corrosion resistance, wear resistance, and aesthetic appearance. At present, the commonly used types of heat sink aluminum profiles in China include: electronic, electrical, computer heat sink aluminum profiles, solar flower aluminum profiles heat sink, power semiconductor heat sink profiles, etc. Aluminum profile radiators are widely used in industries such as machinery, automobiles, wind power generation, engineering machinery, air compressors, railway locomotives, and household appliances due to their superior performance.

Aluminum alloy is widely used in heat dissipation equipment due to its lightweight and beautiful appearance, good thermal conductivity, and the complex shape of aluminum radiators processed. There are three main types of aluminum radiators: flat wide, comb shaped, or fishbone shaped; The outer heat sink of a circular or elliptical shape is radiating; Branch shaped.

Their common feature is that the distance between heat sinks is short, and a groove is formed between adjacent heat sinks, with a large aspect ratio; The wall thickness difference is large, and generally the heat dissipation fins are thin, while the bottom plate thickness at the root is large. Therefore, it brings great difficulties to the mold design of heat dissipation profiles, the manufacturing and production of aluminum radiators. Some aluminum profiles for radiators are relatively easy to produce due to their smaller size and symmetrical shape. Most radiator profiles are flat and wide, with larger overall dimensions and some are asymmetrical. The groove shape between the heat dissipation fins has a large aspect ratio, making production difficult. To successfully produce radiator profiles, it is necessary to cooperate with ingots, molds, and extrusion processes.
