ElectronicsCooling magazine was founded more than 12 years ago with a mission of providing current and practical thermal management information with archival value. I hope you agree this magazine is still delivering on its original promise. The last word in the mission statement is value, and each of us, as a thermal engineer, desires to add value to our projects. Admittedly, … [Read more...]
Electronics Cooling At Higher Pressures … a Positive Displacement Pump Solution
Introduction Many liquid cooling solutions in use today employ cooling system devices that result in system pressure drops limited to <0.5 bar (7.25 psi), which allows these systems to fit within the limits of centrifugal pumps. The evolution of alternative cooling devices has brought about pressure drop requirements >1.0 bar (14.50 psi) in some cases [1]. These higher … [Read more...]
Advanced Cooling Using Meso-Scale Evaporative Cold Plates
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...]
Top 20 Considerations For Selecting Thermal Interface Materials
Introduction Heat is often considered the limiting factor in the advancement of electronics systems. Lower thermal resistance will drive, not follow, future electronic designs. These solutions must be cost effective, user friendly and developed quickly. Thermal interfaces are usually an afterthought to designs but play a huge factor in the performance and reliability to a … [Read more...]
