Intel Develops Micro-Refrigerator To Cool Chips

Spacedonkey writes "Researchers at Intel, RTI International of North Carolina, and Arizona State University have made ultra-thin 'micro-refrigerators' for computer chips. The device uses a thermoelectric cooler made from nanostructured thin-film superlattice that can reduce the temperature by 55C when a current passes through it. In testing, it reduced the temperature on part of a chip by 15C without impairing its performance. The researchers say the component could be particularly useful for cooling hot spots that frequently occur on multi-core chips."

It does not just move the heat

When you move heat, you're concentrating the heat and making the hot side hotter. Heat sinks are rated in Watts/degree so a heat sink that is 10 degrees above ambient will dump heat 5 times as fast as a heat sink at 2 degrees above ambient. Thus, a Peltier device pumping heat into a heatsink will cause the heatsink to run hotter and work more effectively.
