A JAPANESE COMPANY has developed a way of exchanging heat that will use a magnetic fluid and will be used to cool down your microprocessor without needing electricity.

According to the Nikkei Business Daily, Da Vinci's device, developed together with boffins at the University of Tokyo, will use metal alloy nanoparticles mixed with oil. The report said a hollow magnet in the piping will act like a pump to move the magnetic fluid, drawing the nano oil into the heat exchanger and drawing heat from a CPU.

The hot oil then switches to the other side of the heat exchanger where it cools down. And so it goes.

The fact it won't need electricity means that such a heat exchanging pump can be made much smaller than ordinary heat drawing systems. The report said that such heat exchangers would be suitable for notebooks, and will cost a mere ¥1,500 when they go into mass production next year.

¥1,500 = $18.16 AUD
¥1,500 = $13.89 USD
¥1,500 = £7.38

Finally, something new that isn't expensive. And the fact that it doesn't require electricity is awesome. 👍
 
yes, but how does it perform? it sounds like it works very similarly to a heatpipe to me, and heatpipes perform exceptionally well if they're designed properly... Either way, you'll still need electricity. The heatsink assembly won't, but you'll still need fans to cool the heatsink.
 
I want something like this for a desktop. That would rock, especially for silent cpu's.
 
I know they have water cooling.. But they have this oil thing for desktops already?
 
No, they have heatpipe-based heatsinks, which do exactly the same thing as this oil based cooling with less complexity and (i suspect) far faster...
 
This oil thing actually might be faster. Oil is thick, so it will entrap more heat. But i think it also cools off quickly.. Maybe.
 
Yes, oil is thick. (especially compared to vaporized butane, ethyl alcohol, glycol or water). Which means that it'll take longer to make its way along the length of the tube from the heat source (the CPU/GPU/chipset, whatever) to the heat exchanger.

I don't know. Without getting my hands on one of these things to play around with, I'm just hypothesizing based on what I've read in the article and what I know about how this stuff works. :-/

Oil is thicker, but this may be made up for with some planning on fluid transfer ways and, keeping in mind, the thermal conductive properties of oil are much better than that of the liquids used in a heat-pipe setup.
