A-Z of electrical components – H: Heat sinks

16 11 2011

The heat generated by complex devices and circuitry can often threaten the reliability of a product and, in some cases, tamper with the ability of a device to function correctly.

With this in mind, heat sinks have become an essential part of modern electronics manufacturing.

They are used to reduce and control the temperature of items such as microprocessors through sophisticated heat dissipation techniques.

They are basically made up of a small metal structure which includes flat surfaces to ensure good thermal contact with the components that need to be cooled.

A heat sink absorbs and dissipates heat from another object using thermal contact. They are used in a vast range of applications which could include anything that requires efficient and effective protection from heat.


How are heat sinks used?

Within the electronics industry, they are used most frequently for the cooling of electronic devices. Complex circuitry and devices require protection from the extreme generation of heat, otherwise they cannot perform the tasks for which they were designed.

Heat sinks are often used while soldering circuit boards, helping to prevent excessive heat from damaging the complex electronic aspects.

For example, electrical components such as magnetic reed switches can malfunction if exposed to higher powered soldering irons.

Some modern electronic devices can withstand high temperatures because of their specific design, but if there is a doubt over it then heat sinks are an essential tool.
