Introduction Numerous reports over the past ten years or so have described the potential for nanofluids (suspensions of nanoparticles in liquids) to be applied as heat transfer fluids, because of the enhanced thermal conductivity and convective heat transfer characteristics that have generally been observed. A number of review articles have been published on nanofluids [1 � 8], … [Read more...]
When Moore Is Less: Exploring the 3rd Dimension in IC Packaging
Introduction As consumers of electronics we have become spoiled. We not only expect our electronic devices to get smaller, faster, more functional, cheaper, more interconnected, and more reliable, we actually demand it. It would not be a pretty picture either for the consumer or the electronics industry if suddenly the design of our electronic gadgets became static. At this … [Read more...]
Pushing the Boundaries of Heat Pipe Operation
Introduction Heat pipes are well-established two-phase devices used in the electronics cooling industry to transport heat from the point it is generated to the place where it is extracted from the system. Three wick structures are most commonly used to provide the capillary path for the liquid return to evaporation section; these are sintered powder, screen mesh and grooved … [Read more...]
Integrated Heat Pipe Spreader for Improved FBDIMM Memory Module Thermal Management
Introduction Due to the increasing power density in today's industry standard servers, thermal design and cooling is a significant challenge. In a typical server, the two most challenging elements to cool are the processors and the memory modules. The system level fan speeds are directly dictated (in most cases) by both processor and memory temperatures. Due to the fact that … [Read more...]
A Cryocooler In Your Laptop Computer? Maybe…
Introduction A review of the technical and market impediments overcome in the development and eventual acceptance of cryocoolers for space-borne applications may shine light on the prospects for the use of such mechanical refrigeration systems in more widespread commercial uses. This premise is explored by first reviewing space cooler development history, then considering some … [Read more...]
