New Chip-cooling Technology

Posted by samzenpus on from the cool-off dept.

BillOfThePecosKind writes "Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. Purdue researchers funded by Intel have improved the "heat-transfer coefficient" by some 250%. I never liked water cooled systems, and this sounds promising. However I wonder how much ozone one of these things produces."

    You are quite right. The AC has no idea what he is talking about. If only his grasp of "simple heat transfer" matched his arrogance. This is not a sealed chamber. The ions impart momentum to a near wall flow and destroy the boundary layer. Good mixing at the wall = good heat transfer! (The article says as much) These Purdue dudes have a lot of neat electronics cooling stuff going on. I had the pleasure of getting the whole delivery at a seminar last Fall.
