    IBM researchers have developed an innovative approach for improving the cooling of computer chips, an increasingly urgent need given the large amount of heat released by today's more powerful processors and the additional energy required for removing that heat.

    Looking beyond the limits of air-cooling systems, Zurich researchers are taking their concept of branched channel design even further and are developing a novel and promising approach for water-cooling. Called direct jet impingement, it squirts water onto the back of the chip and sucks it off again in a perfectly closed system using an array of up to 50,000 tiny nozzles and a complicated tree-like branched return architecture.

    First lab results are impressive. The team has demonstrated cooling power densities of up to 370 Watts per square centimeter with water as coolant. This is more than six times beyond the current limits of air-cooling techniques at about 75 Watts per square centimeter. Yet, the system uses much less energy for pumping than other cooling systems do.
