Introduction Thermal management of servers and communications equipment has become significantly more challenging over the past several years. As is well known, processor powers have increased to 150 W or more and are projected to continue to rise, despite the move to multi-core designs (and the huge investment in software that this entails) [1]. Rack-level functional density … [Read more...]

A Practical Implementation Of Silicon Microchannel Coolers
Introduction More than twenty-five years ago, Tuckerman and Pease first described the use of silicon microchannel cooling for very high power densities [1]. However, the coolers could not be fabricated easily and pressure drops were very high. As chip power densities are now increasing beyond air cooling limits, a variety of liquid cooling methods are being investigated. Due to … [Read more...]
