Heat sink is a kind of device for heat dissipation of electronic components easy to heat in
electrical appliances. It is mostly made of aluminum alloy, brass and bronze in plate shape,
sheet shape and multi-piece shape, etc. For example, CPU central processor in computer
needs to use quite large heat sink, power tube in TV and power amplifier need to use heat
sink. In general, the heat sink must be coated with a layer of thermally conductive silicone
grease on the contact surface between the electronic components and the heat sink, so that
the heat emitted by the components is more effectively transmitted to the heat sink, and
then radiated to the surrounding air through the heat sink.
