Magnetic heat exchanger will cool down your CPU

@ 2005/04/04

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. µ

well, i know there is in HDD, didn't knew bout cd-rom though but anyhow, wouldn't it influence the one in your hdd, which would cause data loss

There is magnet in your CD ROM and HDD.

Comment from GIBSON @ 2005/04/05

how about data loss? i personally wouldn't really like a magnet being in there, specially in tight places like a notebook

Heatpipe tech was in Chicago computer show back in 1999 when nobody wanted it.

There is limitation to current heatpipe which is the close ratio between ambient and heat source.

we already have a heat exchanger.. it's called heat pipe. the question is if this new technique can move heat faster or not
