A computer that sits comfortably, coolly on your lap. The world s largest chipmaker expects a crush of ultrathin laptops from PC makers in 2009 and unveiled cooling technology this week to make sure these svelte air-flow constrained designs stay cool.
To date, cooling technology has focused on keeping the internal components from getting too hot but not the outside of the computer, according to Mooly Eden, general manager of Intel s Mobile Platforms Group, speaking at the Intel Developer Forum in Taipei this week. Eden s keynote was streamed from the event.
Intel uses laminar jet technology to cool a laptop s skin.
When you design a very thin system, cooling the skin is a very big challenge, said Eden. If you put a laptop on your lap, it can feel very uncomfortable. Very hot. This is one of the biggest hurdles to designing an ultrathin laptop like the MacBook Air or HP Voodoo Envy 133.
If this problem isn’t solved, laptops can t be made thinner and thinner, he said.
Eden showed an animation of a jet engine to prove his point. The inside of a jet engine can get as hot as 1,000 degrees centigrade. But the jet engine s wall must be kept cool because it is connected to the wing where the fuel is. To keep the engine heat away from the wing, laminar air flow cooling is used.
A laminar flow occurs when a fluid–or air in this case–flows in parallel layers.
Intel demonstrated a system using the same laminar air flow technology to move the heat off a laptop s skin. We are licensing it to our customers so they can keep making thinner and thinner laptops, Eden said.
