What is a heat sinks

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.

Today, when the requirements for heat dissipation are constantly increasing, the Japanese have begun to think of using thin and dense heat dissipation fins to fit the heat dissipation bottom plate with huge pressure. This technology can be arbitrarily combined and matched with copper and aluminum fins and copper and aluminum base plates, and also effectively avoids the disadvantage of new thermal resistance caused by uneven heat conduction of various solder pastes during the welding process. It enables customers to have more selectivity and diversity of thermal solutions. However, due to the particularity of its processing, the current mass production still has the problem that the cost is too high.

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.

After using the aluminum extruded heat sink for such a long time, no matter how we change our processing technology, it is difficult to meet the ever-increasing CPU calorific value. The coefficient is much larger than that of aluminum, and the thermal conductivity is doubled, which is of great benefit to our heat dissipation; however, since the hardness of copper is much greater than that of aluminum, it is a severe test for the manufacturing process during the processing. Therefore, the traditional extrusion molding process is no longer applicable to copper, and has to be processed in this cutting method.
