What is this and How it works
A heat sink is a piece of metal which transfers heat from the hot electronic components to the air thus keeping the components at a lower temperature. The basic design of heat sink involves a base and fins which are connected to the base.
Types of Heat Sinks
Heat sinks are classified into many types. On the basis of fin arrangement, heat sinks are of three types.
- Pin type
- Memory cards of servers
- Cooling of graphics cards
- Transistors (BJT, FET, MOSFETS)
- Electronic projects in your labs
- Power supplies
When you should use them
It is strongly recommended to use a heat sink if your circuit has 500 mA (0.5 A) or more current.
