How to produce heatsinks machine

The heatsinks machine is a device used to cool the electronic components that easily generate heat in electrical appliances. They are mostly made of aluminum alloy, brass or bronze. They can be made into plates, sheets, multiple sheet shapes, etc.

 In terms of heat dissipation materials, the thermal conductivity of each material is different. According to the thermal conductivity, from high to low, they are silver, copper, aluminum and steel. But if silver is used as heatsinks machine, it will be too expensive, so the best way is to use copper. Although aluminum is cheap, and aluminum heat sinks are used more, it is obviously not as thermally conductive as copper (only about 50% of copper). Commonly used heat sink materials are copper and aluminum alloy, both of which have advantages and disadvantages.
       Copper has good thermal conductivity, but it is more expensive, difficult to process, heavy in weight, small in heat capacity, and easy to oxidize.
Pure aluminum is too soft to be used directly. Use aluminum alloy with sufficient hardness. The advantages of aluminum alloy are low price and light weight, but its thermal conductivity is much worse than copper. For ordinary users, the aluminum heatsinks machine is sufficient to meet the heat dissipation requirements.
