It is usually made of aluminum alloy, brass or bronze in the shape of plates, sheets, or multiple sheets. For example, a computer's CPU central processing unit requires a fairly large heat sink, as do power tubes, line tubes, and power amplifier tubes in televisions. Generally, a layer of thermal conductive silicone grease should be applied to the contact surface between the electronic components and the heat sink during use, so that the heat generated by the components can be more effectively transferred to the heat sink, and then dissipated to the surrounding air through the heat sink.
