      Several common manufacturing materials for electronic profile radiators

      Nowadays, the electronic products around us are becoming more and more diverse, and the thin and light appearance is the current development trend of electronic products. Therefore, it will also face a challenge. How to fully help electronic products to dissipate heat in a limited space is a matter that requires special attention. Let's take a look at several commonly used materials for making radiators today.

      One. Plastic radiator

      The common plastic radiator is made by filling some metal oxide powder, carbon powder, fiber or ceramic powder in the plastic to improve its thermal conductivity. This kind of plastic radiator is extremely light in weight, which is in line with the needs of electronic products. In addition, it has strong plastic appearance and low cost, which is favored by many manufacturers. However, compared with the heat sink made of metal alloy, its thermal conductivity is not stable, the thermal conductivity varies greatly, and it cannot ensure that it can perfectly adapt to the working environment. It may even deform after working for a long time, so its safety and stability are Needs to be improved.

      Two, copper radiator

      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 radiators to ensure that it has a long service life. Secondly, the heat dissipation capacity of the copper radiator is considered to be excellent. It tends to absorb heat quickly and dissipate heat quickly. The heat dissipation capacity and corrosion resistance are stronger than that of aluminum. Although the copper radiator has its advantages, the price is often very expensive.

      Three, aluminum radiator

      Aluminum alloy is considered to be the hotter radiator manufacturing material on the market, among which the more high-quality aluminum alloys are 6063 and 6061. It can fully meet the needs of electronic products for heat dissipation, and the characteristics of light weight, easy processing, beautiful appearance, and affordable price make it particularly widely used. In order to make the radiator aluminum profiles produced more decorative appearance, longer service life, and stronger heat dissipation performance, multiple processing techniques will be carried out on the products. Through sandblasting, wire drawing and laser technology, the surface of the radiator molded is cleaner and smoother, and the decoration is more enhanced. With the addition of electroplating, anodizing and baking paint processes, by adding electroplating layer, oxide layer and special material paint on the surface to improve the overall wear resistance, corrosion resistance and heat resistance of the radiator, the performance and durability of the radiator are improved. The degree has been qualitatively improved.

      Four, graphite radiator

      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 radiators. However, the price of graphite material itself is very expensive. The later processing fee and die-cutting management fee of graphite radiator are sometimes even more expensive than the material cost. Therefore, the cost of using graphite radiator is very expensive and the application is not very extensive.
