Scientists aim to take the heat off computers with a new twist on an old idea: using ionic wind to create a cooling air flow over a computer chip.
The UW's "cooling chip" has two parts, an emitter and a collector. The emitter, which is one-three-hundredth of the width of a human hair, creates the ionic air flow. The collector captures the ions at the other end of the chip. This ionic motion carries away heat and cools the chip. The level of cooling can be controlled by how much voltage is applied to the system.Spiffy.
