Researchers look to air-condition computer chips

(AP) -- Purdue University scientists have taken a page from air conditioner technology in their quest for a new way to cool down ever-more powerful computer chips. Their experimental system, which flushes a refrigerant through tiny channels cut into chips, is intended for the high-power electronics found in radar and advanced weapons systems such as lasers, said Issam Mudawar, a mechanical engineering professor at Purdue.
