What Is a Heat Sink?
Heat sink to transfer the heat from electronic components.
First, the heat sink takes in thermal energy from the heat source.
The next thing is it distributes that heat across a large area.
Next, the system uses an airflow to deliver this heat energy into the environment.
Thus, electrical components stay at a safe operational temperature.
There are a wide range of different structures in which manufacturers produce heat sinks.
Common products include:
- Extruded Heat Sink
- Skived Fin Heat Sink
