Electrical appliances that contain electronic components that are susceptible to overheating, such as refrigerators and freezers, use a heat sink to keep the components cool. Aluminum alloys, brass, and bronze are among the materials used to make the majority of them, with a few exceptions. They can be formed into a variety of shapes, including plate, flake, and multiple flake shapes, among others. In electronic devices such as the computer, the power tube, the line tube in the television, the power amplifier tube in the power amplifier, and the power amplifier tube in the power amplifier, heat sinks are utilized.
Aluminized Extruded Heat Sink (aluminum heat sink):
Aluminum has been a popular heat sink material since its introduction into the market in the 1970s, owing to its soft and straightforward processing characteristics. According to a simple explanation, following the high-temperature heating of aluminum ingots, the aluminum liquid flows through an extrusion mold with a groove under high pressure to form the initial heat sink and, after cutting the initial heat sink, Aluminum Extrusion is formed into the common heat sink.
The aluminum extruded heat sink is relatively inexpensive, and the technical hurdle that must be overcome is not prohibitively difficult to overcome. While the heat sink fin’s thickness cannot be greater than 1:18 because of material limitations, it is possible to increase the heat dissipation area in a limited amount of space by reducing the length of the heat sink fin’s thickness. Comparatively speaking, the aluminum extruded heat sink has poor heat dissipation properties when compared to other materials, making it unsuitable for use with a high-frequency processor.
A forged steel heat sink serves as a heat sink.
This type of fin has the advantage of being more durable because the height of the fins can reach more than 50mm and the thickness is less than 1mm. Although the deformation resistance of the metal is high during forging, it is easy for the metal to crack when deformed during the process due to the low plasticity of the metal. The extremely high cost of the product is also due to the extremely high cost of the equipment and molds that were used in its manufacture.
Special tools will be used to cut the material into layers of fins, and the fins will be cut into layers of the material using the special tools. Heat dissipation fins as thin as 0.5mm in thickness are possible, and because the heat sink’s base, as well as its fins, are integrated, there will be no problem with the heat sink’s interface impedance. But because of the amount of waste generated by this cutting process, the yield during the manufacturing process is relatively low.
