Heat sinks are used in electrical appliances that contain electronic components that are susceptible to overheating, such as refrigerators and freezers. 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 CPU, and the line tube in the RAM are all examples

Aluminized Extruded Heat Sink (aluminum heat sink) is a type of heat sink made of aluminum

Following the high-temperature heating of aluminum ingots, a simple explanation states that 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, it is formed into the common heat sink. Aluminum has been a popular heat sink material since its introduction into the market in the 1970s because of its soft and straightforward processing characteristics.

Because of material limitations, the aluminum extruded heat sink's thickness cannot be greater than 1:18; however, 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 Extrusion heat sink has poor heat dissipation properties; however, the technical hurdle that must be overcome is not prohibitively difficult to overcome.

A heat sink is made of forged steel and is used for cooling purposes

Due to the high deformation resistance of the metal 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. The product's extremely high cost is also due to the extraordinarily high cost of the equipment and molds that were used in its manufacture.

Because of the amount of waste generated by this cutting process, the yield during manufacturing is relatively low. 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. However, because of the amount of waste generated by this cutting process, the yield during manufacturing is relatively low, as is the yield during manufacturing.
