Heat sink is a kind of heat sink device for the electronic components in electrical appliances that are easy to generate heat. It is composed of aluminum alloy plates, sheets, sheets and so on. For example, the CPU in a computer needs to use quite large heat sink. In general, heat sinks should be coated with a layer of heat-conducting silicone grease on the contact surface between electronic components and heat sinks in use, so that the heat emitted by the components can more effectively conduct to the heat sinks, and then be distributed to the surrounding air through the heat sinks.
