By Raffaele Luca Amalfi, Ph.D., Jackson Braz Marcinichen, and John Richard Thome, Ph.D. CONTEXT AND NEW COOLING TECHNOLOGY Heat dissipations of servers and their racks in datacenters are reaching ever increasing levels, breaching the economical heat removal limits of traditional air-based cooling technologies. Currently, about 40% to 45% of the total datacenter energy … [Read more...]
Thermal Facts & Fairy Tales: Whatever Happened to the Predicted Data Center Energy Consumption Apocalypse?
As the title indicates, since the middle of the last decade, there have been very pessimistic projections regarding the growth of the total annual energy used by data centers in the U.S. One of them suggested that by 2030, the energy consumption in the U.S. in the IT sector would be roughly 60% of that used by its entire industrial sector. [1,2,3] What was the origin of this … [Read more...]
Using Electrical Capacitance to Evaluate the Thermal Mechanical Stability of Thermal Interface Materials
BY: Lauren Boston, Andrew Yu, Timothy Chainer, Edward Yarmchuk, and Michael Gayness To improve cooling of electronic components, a heat spreader is typically attached to the component to spread the heat laterally and facilitate the heat removal by a heat sink. To ensure good thermal conduction between the heat spreader and heatsink, a thermal interface material is applied … [Read more...]
What…Use Lasers and LEDs for Cooling?
In a recent blog “Some New Cooling Ideas are Needed Here,” I suggested (hoped?) that someone would figure out how to leverage the thermal laws of physics to devise innovative cooling systems which go beyond widely used, conventional techniques of conduction, convection, and radiation. The reason for looking beyond these solutions is that they seem to have reached a limit as to … [Read more...]
Air Ionization Techniques for the Cooling of Electronic Devices: Analysis of the Different Effects of Design Features on Cooling Performance
Rotary fans have been used to cool electronic devices using forced convection applications to achieve the required heat transfer dissipation. In recent years, there has been an increasing trend to miniaturize the size and maximize the efficiency of the electronic devices which, in turn, increases heat generation. The use of rotary fan cooling conflicts with these new trends due … [Read more...]
