It is well known that the operating temperature of an electronic device directly determines its service life and stability, and as the computing power of the PC increases, the problem of power consumption and heat dissipation becomes an unavoidable problem. In order to keep the working temperature of each component of the PC within a reasonable range, it is necessary to control not only the temperature of the environment but also the heat treatment. The role of the heat sink is very important. Today, we mainly share the manufacturing process of the heat sink.
Process technology
This is an excellent heat-dissipating material widely used in modern heat dissipation. Most of the industry uses 6063 T5 high-quality aluminum material, for example, amd cooling solution, its purity can reach more than 98%, its thermal conductivity is strong, its density is small, and its price is cheap, so it has been obtained by major manufacturers. favorite.
According to the thermal resistance of Intel and AMD CPUs and the calorific value of the AMD CPU, the aluminum extrusion type manufacturer formulates the corresponding mold, heats the aluminum ingot to a certain temperature, changes its physical form, and then obtains various heat dissipation in the mold.
Although the price of the aluminium extrusion heat sink profiles is low, it is limited by the softness of the aluminum material itself. Therefore, the manufacturer has increased the heat dissipation area, and the manufacturer has proposed a suitable one under the requirement of the same heat dissipation space. The solution is to encrypt the fins, thereby increasing the number of fins; bending the fins to increase the heat dissipation area; heating the aluminum ingot from the solid state to the liquid state through the mold, and then cooling to become a heat sink.
The precision of the mold directly affects the overall shape and heat dissipation of the heat sink. Therefore, more manufacturers have begun to think of cutting the shape of the aluminum ingot directly with the precision tool of the processing machine, so that no deformation occurs during the processing. It does not allow various impurities to enter the heat sink during the aluminum extrusion process, and also maximizes the heat dissipation area. Such as zipper fin heat sink, skived fin heat sink, plate fin heat sink, splayed pin heatsink and so on.
Aluminum, copper stack heat sink
The copper and aluminum sheets are folded into various shapes of heat sinks, and then welded together with appropriate heat sink base plates to achieve heat dissipation requirements and speed up the progress of production.
The copper-embedded technology is to unify the advantages of fast heat transfer, high density and strong heat absorption capability of copper, and the advantages of light weight, low price and large output of traditional aluminum extrusion type;
The copper-infused heat sink utilizes the characteristics of fast heat absorption and strong heat conduction capability of copper, and quickly brings a large amount of heat generated by the CPU operation to the nickel-plated copper block on the surface, and the copper block and the aluminum-extruded heat sink enable a large amount of heat energy to be fast. It spreads onto the aluminum extruded heat sink and is carried away by the rotation of the fan.
The above is the common manufacturing process of the heat sink. If you want to know more about the heat sink and how to choose different types of heat sink, please freely contact us.
