Several common making materials of electronic profile radiator
Nowadays, there are more and more kinds of electronic products around us. When we choose them, we will not only compare their functions, but also consider their appearance. The current development trend of electronic products is that they are slim and light in appearance. Therefore, it will face a challenge, that is, the internal space of electronic products becomes more and more narrow, but the heat dissipation capacity has always been a problem that electronic products can not be ignored, how to fully help electronic products in a limited space heat dissipation is a point that needs special attention.
This asks radiator to accomplish qualitative light, heat conduction performance is strong, plasticity is strong, rely on finite dimension to develop the biggest come loose to come loose performance only, ability is electronic product to accomplish come loose to escort on real sense. So what kind of material can be chosen to produce the appearance of the size of the requirements without losing the effect of radiator? Here's a look at some of the common materials used to make radiators.
Plastic radiators have been developed and popularized in zhejiang, Beijing, shandong, xi 'an and other places. Common plastic radiators are made by filling some metal oxide powder, carbon powder, fiber or ceramic powder in plastic to improve its thermal conductivity. This kind of plastic radiator quality is extremely light, very accord with the demand of electronic product, add appearance plasticity is strong, the characteristic with low cost got the favour of many manufacturer.
However, compared with the radiator made of metal alloy, its thermal
conductivity is not stable, and the thermal conductivity coefficient changes
greatly, which cannot ensure that it can adapt to the working environment in a
good way. After working for a long time, it may even produce deformation.
Therefore, its safety and stability still need to be improved.
Copper is chemically unstable, making it difficult to react with oxygen and water in the air at room temperature, so manufacturers can ensure its long service life without the need for sophisticated post-processing of copper radiators. Secondly, the heat dissipation capacity of copper radiator is excellent, often heat absorption is fast, heat dissipation is also fast, heat dissipation capacity and corrosion resistance are stronger than aluminum material.
Although copper qualitative radiator has its advantage, but the price is often very expensive, limited economic conditions are generally not recommended to consider using this kind of radiator. And the quality is too heavy to meet the requirements of light and thin electronic products.
Aluminum profile radiator
Aluminum alloy is a hot radiator manufacturing material on the market, among which aluminum alloy 6063 and 6061 are relatively high quality. Although the heat dissipation performance is not as good as copper, the heat dissipation coefficient can reach 201W/mK, which can fully meet the requirements for heat dissipation of electronic products. With the characteristics of light weight, simple processing, beautiful appearance and affordable price, it is widely used.
Electronic profile radiator production materials
The electronic profile radiator produced by Honggai is made of aluminum alloy 6063/6061. In order to make the radiator more decorative in appearance, longer in life and stronger in heat dissipation performance, the product will be processed by multiple processes. Through sandblasting, wire-drawing and laser process, the radiator surface is more clean and smooth, more decorative. In addition to electroplating, anodizing and baking process, the overall wear resistance, corrosion resistance and heat resistance of the radiator are improved qualitatively by adding electroplating layer, oxidation layer and special paint on the surface.
Graphite as a new type of heat conduction and heat dissipation material, although it is mainly made of a single carbon element, it has thermal conductivity performance comparable to that of metal materials. Compared with copper and aluminum metal, it is lighter in quality and more stable in chemical performance. It can be ultra-thin. However, the price of graphite material itself is very expensive. The processing fee and die cutting management fee of graphite radiator in the later stage are sometimes even more expensive than the material fee. Therefore, the cost of using graphite radiator is very expensive, which is not widely used.
