The main features of aluminum die-casting process for heat sink
Good thermal conductivity
Aluminum alloy has good thermal conductivity and can quickly conduct heat to the surface of the heat sink, accelerating heat dissipation.
Lightweight
The low density of aluminum makes the radiator lightweight, making it easy to install and use in products with weight requirements (such as automobiles and electronic products).
Moderate strength and rigidity
Although light, aluminum alloy has sufficient structural strength to withstand certain mechanical loads.
High molding precision
Die casting can produce heat sinks with complex structures and precise dimensions, and is suitable for mass production of parts with high consistency.
High heat dissipation efficiency
Die casting can be used to design a thin-walled, dense fin structure to increase the heat dissipation area and improve heat dissipation efficiency.
Good surface quality
The surface of die castings is smooth and can be directly treated (such as painting, anodizing, etc.) to improve appearance and corrosion resistance.
Can be mass Produced with high efficiency
Die casting has a short production cycle and can be automated, which greatly improves production efficiency and reduces costs.
Recyclable
Aluminum alloy can be recycled and reused, which is in line with the green environmental protection trend.
These characteristics make aluminum alloy die-casting heat sinks widely used in LED lighting, communication equipment, automotive electronics, computer motherboards, power modules and other equipment that require heat dissipation.
