Aluminum shovel tooth is also called SKIVING technology. In simple terms, it is to cut a whole piece of aluminum or copper according to the needs by a special shovel machine to cut fins with a standard pitch and a certain thickness and height. Shovel tooth, Crimped Fin Due to the continuous increase of CPU frequency, the biggest disadvantage of traditional copper-aluminum bonding technology: welding, riveting, copper embedding, etc. lies in the interface thermal resistance. The interface thermal resistance determines the overall heat dissipation capacity of the radiator. Even if the interface thermal resistance can be very small, AVC's latest shovel tooth, crimped Fin technology boldly improves the traditional copper-aluminum bonding technology, which uses more than 60 tons of pressure to bond aluminum to copper In the base of the chip, and no medium is used between aluminum and copper. From a microscopic point of view, the atoms of aluminum and copper are connected to each other to a certain extent, thus completely avoiding the drawbacks of traditional copper-aluminum bonding to produce interface thermal resistance, and greatly improving The heat transfer capacity of the product, therefore, under the trend of increasing CPU power in the future,
Our company currently uses aluminum 1060 and aluminum 6061, 6063 as its main products, and it is also customized according to customer requirements.
Due to the use of high-precision cutting technology, the aluminum shovel heat sink is integrated and formed. Compared with other processing technologies, the same volume of raw materials can cut a larger heat dissipation area, and the heat transfer performance is more stable. The heat dissipation effect under the same conditions is traditional The efficiency of the gear or glue-welded radiator is more than 1.5~2 times, thereby improving the heat dissipation efficiency and prolonging the service life of heating components.
In the heat dissipation requirements, the toothed heat sink uses thin and dense heat dissipation fins to fit the heat dissipation base plate with huge pressure. This technology can be combined and matched with copper and aluminum fins and copper and aluminum base plates at will, and it is also effective It avoids the disadvantages of the unbalanced heat conduction of various solder pastes during the soldering process, resulting in new thermal resistance, allowing customers to have more choices and diversity of thermal solutions
Aluminum shovel teeth are mainly used in industries with high heat density and high power consumption and heat dissipation requirements. They are widely used in the power, medical, communications, industrial control, and server industries. Shovel tooth and crimped Fin technology will become the future wind The leading technology in the manufacture of cold radiators. . .
