Most of the electronic active components are made of semiconductors. Rise or fall in temperature will change the conductivity of a semiconductor. So in order to prevent it heat sinks are used in circuits.

A heat sink is a device to improve the purity of the electrons in an electrical circuit?

There is no such thing as the "purity of electrons". A heat sink is used to keep a device reasonably cold.


Why is a heat-sink used on some equipment?

The main purpose of a heat sink is to dissipate excessive heat away from the device that it is attached to. Some small integrated circuit components are so physically small that an over excess of heat generated by themselves would destroy the device. The heat sink is placed on the IC to prevent this from happening.


What is the function of a processor heat sink?

To sink the heat.


How does a heat sink work in the power supply?

A heat sink works on the principle of thermal transfer. The heat sink transfers heat from the chip to the air, wicking heat away.


Is water a type of heat sink?

Yes! Water is a heat sink.


Why is it called a heat sink?

Probably because it draws/absorbs the heat making the heat "sink" into it


How are heat sink and carbon sink related?

heat sink is when heat is absorbed into any type of environment, including the aquatic ecosystem; and carbon sink is when CO2 is absorbed into any type of environment including the terrestrial ecosystem.

How would you minimize the heating effect of a current in a circuit?

BY reducing the resistances of the circuit, By using Maximum transfer theorem and Joule's law. Copper wires are better conductors than, for instance, than aluminum wires. After insulation, I placed the circuit in water to keep it from overheating (big heat sink).


When upgrading a CPU what must be applied between the new CPU and the heat sink fan?

Thermal grease to allow heat to transfer to the heat sink.
