Introduction

Cooling of fabricated chips is greater concern for scientist.

The generated heat should be carried away.

Our paper aims to propose a method of cooling the

fabricated chips using nanotechnology

Existing method

Cooling techniques

Active Passive Using liquid

Cooling Cooling


4/16

Disadvantages

Some external agencies are used.

They are expensive

Prone to breakdown.

Noisy

Proposed method

cooling techniques

Using Air

(self cooling with the help of nanotechnology)

Nanotechnology

The word nanotechnology is derived from the Greek

word nanos meaning dwarf.(10^-9)

Nanotechnology involves working with matter at the

scale of one-billionth of a metre (1mm).

It is the art of manipulating matter at the atomic scale

Methods

Two regions of cooling chips

Ion Generating region

Ion pumping region


8/16

Ion generating region

A carbon nanotubes is a sheet of carbon atoms joined

in a pattern of hexagons and rolled into a cylinder

The negatively charged nanotubes discharge

electrons toward the positively charged electrodes.

The generated ions causes the ionization of air.

Nano lightning

This ionization of air leads to an imbalance of charges

that eventually result in lightning bolts.

Lightning is created with 100 volts or less, we are

generating lighting on a nano-scale here.

The ionized air molecules cause currents to flow.


10/16

Ion pumping region

This region consists of a series of three electrodes with

the first one highly positive

the next one less positive

the last one negative.

The voltages are rapidly switched from one electrode.

As the ions move forward, they make repeated

collisions with neutral molecules, producing the breeze.


11/16

Corona wind

A corona wind is created by the ions that follow an

electrical field set up by opposite charges.

Collisions between ions and neutral air atoms

propelling the air forward is called the corona wind

effect .

This combination creates an environment so that the

ions are pumped out resulting in an ionic breeze which

cools the computer chips


12/16

Advantages

More reliable and noiseless.

Increase the life expectancy of the chips

Size of computers will be smaller

Self cooling of chips,no external means of creating air.

more advanced circuitry can be fabricated within a

single chip.


13/16

Future scope

The design might replace the carbon nanotubes with a

thin film of diamond, which would

sturdier and easier

The grain boundaries in the diamond film

provides electron emission and ion generation.

Conclusion

Cooling of chips by external sources like fan and

conventional fans are merely impossible.

Hence we use an alternative and innovative source

for cooling of chips without external source.
