Heat sinks are generally steel, aluminum, copper, copper and aluminum composite, stainless steel and other. Which is the high pressure of steel, high heat, good function, durable, but afraid of oxygen erosion; aluminum heat fast, good decorative, resistant to oxidation, but afraid of alkaline water corrosion, and not suitable for high-level living conditions, Because the water pressure is small; copper corrosion resistance, beautiful shape, the best thermal conductivity, the fastest heat, but the price of your side. In the general heat dissipation working conditions, iron, steel, aluminum, copper four kinds of material thermal efficiency is not very different, so what kind of material can be selected according to the specific cooling environment. But need to be reminded that in the current market, there are still a small number of enterprises choose low-cost low-quality non-environmentally friendly raw materials, or to take recycling materials, processing, low prices behind the huge potential security risks. Such products from the appearance of view, consumers are difficult to see what flaws, but because of the production process itself, "inherent deficiencies", long after use, all kinds of hidden dangers will gradually reveal, , Endless trouble.
Dongguan heat sink when buying the second point: we can consult more, as much as possible to understand the product production process. The face of all kinds of heat sink products, expert gate, the layman can only watch the fun. Although the appearance of various types of products is not different, but different brands of heat sink products in the process there are many different, this difference often determines the quality of the product is good or bad. At present, Dongguan squeeze the heat sink product manufacturing process of the key differences in the performance of the material and surface treatment.
Dongguan extruded heat sink due to the material, production technology, the use of functional aspects of their own characteristics, so in the surface treatment also put forward higher requirements.
