Intel on Notebook Cooling Jet Engine Style – Sort of
Is your notebook getting too warm for your legs ? Intel is actively trying to sooth the burns with its new cooling technology that closely resembles the way real jet engines are kept cool on the outside.
Intel has been hard at work looking into the ever increasing problem of warm legs with something called ‘Laminar Flow’. Laminar Flow occurs when a fluid or gas/air flows in parallel layers, causing a non turbulent way of directing heat and/or hot air away from a surface or area.
Mooly Eden, head of Intel Mobile Platforms Group, at this week’s Intel developer forum in Taiwan, showed an animation of a jet engine to prove his point about laminar flow. The inside of a jet engine can reach upwards of 1,000 degrees centigrade – not that your notebook will ever reach these temperatures. However, the walls of a jet engine need to be kept cool as they are joined to the wing of the aircraft where the fuel is normally stored – laminar flow is used in keeping things cool.
Intel demonstrated application of laminar flow technology to move the heat off of a notebooks skin. “We are licensing it to our customers so they can keep making thinner and thinner laptops”, quoting Eden.
Eden also touched a little about Calpella, the next-gen mobile platform that will mark Nehalem’s mobile debut in the second half of 2009 – going on about how Calpella will incorporate processors with integrated graphics cores. He also added that cores in Nehalem chips can be dynamically shut off to conserve power and run cooler.

How fitting - most of my half-decent laptops have sounded like jet engines...
Hmm, more details required, this does not make sense. Everyone knows that turbulent flows have better heat transfer characteristics, which is why you actually try to *create* turblulent - not laminar - flows, in these applications.
i dont think its for heat transfer, but exactly the opposite. they don't want the heat to be transfered to the bottom and as an extra bonus the air that does get heated will be exhausted ouy somewhere.
Holy spam, batman.
If I remember my fluid dynamics lessons well, laminar flows have better heat transfer characteristics because it has a more uniform interaction between the fluid/solid interface, and because the fluid flow rate is also faster for the same amount of kinetic energy. But it's only achievable at lower speeds, because the shearing effect between the stationary surface and the flowing fluid eventually causes turbulence.
