Liquid cooling also for smartphones | How to cool a phone in a near future

It has been a long time since desktop PC users have at their disposal all kinds of components to turn to liquid cooling and thereby ensure acceptable component temperatures even when they work beyond their factory specifications and we do some overclocking operation on them.

A group of engineers at Fujitsu Laboratories in Kawasaki (Japan) have now devised a system that could be applied to mobile devices. As in the case of the PC, the idea is to use a small loop with an extra-slim copper tube filled with water. At one end that water is vaporized, and at the other is condensed to re-circulate and cool these internal components again.

The real innovation is to make that this whole cooling system is compact enough to be integrated into a smartphone. In the case of this system, the small tube and evaporator sections have a thickness of 0.6 mm, while the capacitor has a thickness of 1 mm. The total circuit measures 58 mm by 107, effectively allowing manufacturers to consider this option.

Those responsible for this project indicate that previous attempts to apply this concept remain far behind, and their device provides heat transfer five times higher than those previous attempts. And not only that: the disposal of the different elements can be customized, so as to get adapted to the shape of the product.

Now the goal is to refine the design, to make production costs be reduced and implement this solution on mobile devices from 2017. However this application can go much further, and these engineers are assessing their application also in fields such as communications infrastructure or medical equipment as well as a small portable that can also benefit from a system of this kind.
