What is extruded heat sink?
Extruded heat sink is also known as heat sink extrusion or extruded aluminum heat sink, heat sink extrusion with beautiful appearance, light weight, good heat dissipation performance, energy saving effect. Aluminum heat sink extrusion technology is to heat aluminum ingots to 520~540℃ at high temperature, under high pressure to let the aluminum liquid flow through the heat sink extrusion mold with grooves, to make the extruded heat sink material. Then, after cutting and cutting the heat sink extrusion material, the extruded aluminum heat sink we often see is made.
Aluminum heat sink extrusion technology is easy to realize, and the cost of equipment is relatively low, so it has been widely used in the low-end market in previous years. AL6063 is a commonly used for aluminum heat sink which has good thermal conductivity and machinability. Shunho heat sink solutions relying on long-term accumulated technical experience and production process, sets aluminum alloy profiles with good thermal conductivity and other characteristics and develops a customized aluminum extruded heat sink that can meet customers' requirements of product differentiation, specialization and personalization.
The finished extruded heat sinks surface is anodized to improve the corrosion resistance, wear resistance and appearance of aluminum. At present, the commonly used types of extruded aluminum heat sink in China are electronic heat sink, computer heat sink , sunflower heat sink, power semiconductor heat sink and so on. Because of the superior performance, extruded aluminum heat sinks are widely used in: machinery, automobile, wind power, construction machinery, air compressor, railway locomotive, household appliances and other industries.
Extruded heat sink is generally high power heat sink and cooling systems. We can provide reliable natural convection environment solutions according to the existing mature technology of extruded aluminum heat sink. Aluminum heat sink extrusion molding can be achieved through the mold, which can realize the complex structure of heat sink fin. These complex radiating fins make the radiating surface area larger and reduce the cost and time of aluminum processing.
The mainly advantages of aluminum extruded heat sinks as following:
1. More efficient than stamping heat sinks
2. More cost saving than mechanical processing
3. There are a variety of standard shapes and sizes
4. Easily customized than copper lighter, obvious advantages
