What is a heat sinks

This is an excellent heat dissipation material widely used in modern heat dissipation. Most of the industry uses 6063 T5 high-quality aluminum material, its purity can reach more than 98%, its thermal conductivity is strong, its density is low, and its price is cheap, so it has won the praise of major manufacturers. favor. According to the thermal resistance value of Intel and AMD CPU and the consideration of its calorific value, aluminum extrusion manufacturers formulate corresponding molds, heat the aluminum ingots to a certain temperature to change the physical form, and then get out of the mold. We have all kinds of raw materials for heat sinks; we can then use them after cutting, grooving, grinding, deburring, cleaning, and surface treatment.

Although the price of aluminum extruded heat sinks is low and the manufacturing cost is also low, due to the limitation of the soft texture of aluminum itself, the ratio of the thickness of the fins to the height of the fins generally does not exceed 1:18, so each PC manufacturers are constantly increasing the heat dissipation area and keep the heat dissipation space unchanged. The manufacturers have proposed a more suitable solution to encrypt the fins to increase the number of fins; bend the fins to increase the heat dissipation Area; heating the aluminum ingot from a solid state to a liquid state through the mold, and then cooling it becomes the heat sink we want.

The most perfect solution to this compromise solution is the copper embedded technology pioneered by AVC. This is a harmonious unification of the advantages of fast heat conduction, high density and strong heat absorption capacity of copper and the advantages of traditional aluminum extrusion, such as light density, low price and convenient mass production.

Although the effect that cannot be achieved by this kind of aluminum extrusion is solved in terms of heat dissipation area, the precision of the mold directly affects the overall shape and heat dissipation capacity of our heat sink, so more manufacturers begin to think of using precision machining tools. Directly cut the aluminum ingots into the shape we want, so that there will be no deformation during the processing, and various impurities will not enter the heat sink during the aluminum extrusion process. Maximum heat dissipation area.
