Enough of that interrupting sound that makes the experience of working on a lappy somewhat jaded! It was just a matter of time before someone thought of a radiant way to do away with those ‘large’ embedded cooler fans and the ionic cooling system has finally arrived. It was in the wings for a couple of years and now Tessera, a San Jose based chip packaging company has integrated it into a laptop and proved that it really works. This technology uses ions to push air molecules capable of producing a cooling breeze- over a hot processor. The ionic cooling system extracts 30% more heat from a laptop than a cooling fan and that too, using half the energy of what a fan requires. The entire process is cheerfully a silent operation which makes experts believe that it is a huge landmark.
The ionic cooler is stationed near a vent inside the laptop. A set of heat pipes draw heat from the processor to the cooling system. The cooling device has two electrodes- the one that ionises air molecules viz. nitrogen and the other that collects those molecules. On application of the voltage the ions flow from the former to the latter and their momentum forces neutral air molecules over the hot processor, cooling the same in process.
