The heat sink is a device specially designed to dissipate heat for electronic components in electrical appliances. It can be made of aluminum alloy, brass, bronze and other materials. In use, a layer of thermally conductive silicone grease is usually applied to the contact surface of the electronic component and the heat sink. , More conducive to heat dissipation. For different materials, the thermal conductivity is different, and the price is also different. On the whole, aluminum heat sinks are cost-effective, and 1100 aluminum plates can be used.
1100 aluminum plate is industrial pure aluminum with an aluminum content (mass fraction) of 99.00%, which cannot be strengthened by heat treatment, and has high corrosion resistance, electrical conductivity and thermal conductivity, and good plasticity. Aluminum has a low density and is not easy to oxidize (the surface can produce dense alumina after oxidation to prevent further oxidation), and the price is relatively low compared to copper. Therefore, most heat sinks now choose aluminum or aluminum alloys due to a combination of multiple factors.
