Nowadays, electronic products are becoming more and more diverse. Thinner appearance is the current development trend of electronic products. As electronic products become thinner and thinner, space inside becomes smaller and smaller, so heat sinks are also facing increasing challenges. Shengyida is the leading custom heat sink manufacturer in China, has more than 10 years of experience in the heat sink industry. The heat sink is made of lightweight, strong thermal conductivity and strong plasticity. Only by relying on the limited size to maximize the heat sink performance can it truly In the sense, provides heat dissipation escort for electronic products.
1. Plastic heat sink
The thermal conductivity of the plastic heat sink is relatively poor, and if it works for a long time, the heat will be deformed, and it cannot be guaranteed to adapt to various working environments. Therefore, the safety and stability of the plastic heat sink need to be improved. Now when making plastic heat sinks, some metal powder, carbon powder, etc. are added to improve the heat dissipation performance. The quality of plastic heat sinks is extremely light, which meets the needs of electronic products. In addition, the plastic heat sink has a strong appearance and low cost. Favored by fewer manufacturers.
The chemical properties of copper are unstable, and it is difficult to react with oxygen and water in the air at room temperature. Therefore, manufacturers do not need to perform sophisticated post-processing on copper heat sinks to ensure that it has a long service life. Secondly, the heat dissipation capacity of copper heat sinks can be regarded as excellent. It tends to absorb heat quickly and dissipate heat quickly. The heat dissipation capacity and corrosion resistance are stronger than aluminum.
Aluminum alloy is the most popular heat sink manufacturing material on the market. It has relatively lightweight, good heat dissipation performance, convenient processing, and low price. Therefore, many heat sink manufacturers like to use aluminum alloy to make heat sinks.
4. graphite heat sink
Graphite is a new type of heat conduction and heat dissipation material. Although it is mainly made of a single carbon element, it has a thermal conductivity comparable to that of metal materials. Compared with copper and aluminum, it is lighter in weight and has more stable chemical properties. To be ultra-thin, it is indeed a very good material for making heat sinks. However, the price of graphite material itself is very expensive. The later processing fee and a die-cutting management fee of graphite heat sink are sometimes even more expensive than the material cost. Therefore, the cost of using a graphite heat sink is very expensive and the application is not very extensive.
