Aluminum alloy is widely used to make heat sink materials because of its light weight, beautiful appearance, good thermal conductivity, and easy processing into complex shapes. There are three main types of aluminum alloy heatsink materials: flat and wide, comb-shaped or fishbone-shaped; round or elliptical radiating fins; tree-shaped.

Their common characteristics are: the distance between the radiating fins is short, a groove is formed between two adjacent radiating fins, and the aspect ratio is large; the wall thickness difference is large, the general radiating fin is thin, and the bottom plate thickness at the root is large. Therefore, it brings great difficulty to the mold design, manufacture and production of heat dissipation profiles.

At present, the heatsinks used in foreign countries are generally made of aluminum extruded profiles, but the traditional cast aluminum heatsinks are still used in China and above. The process performance and efficiency of the cast aluminum heatsinks are low. Aluminum heatsinks are used instead of cast aluminum heatsinks. It is imperative. Weihua Technology has been professionally producing aluminum extruded heatsinks for many years, and can provide you with high-efficiency and high-performance heatsinks.

Whether you are designing a computer, LED lighting or other electronic equipment, you need a heat sink. The heatsink absorbs and dissipates the heat of these devices to cool them.
