Heat Sink: What is it Made of, Its Types and Applications

Many electronic components contain a heat sink with them. In this post, you’ll learn how a heat sink works, types of the heat sink and its area of applications.

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.
  1. Pin type
  2. Straight
  3. Flared

Practical applications

  1. Memory cards of servers
  2. Cooling of graphics cards
  3. Transistors (BJT, FET, MOSFETS)
  4. Electronic projects in your labs
  5. 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.
