IN THE LAST WINTER ISSUE OF ELECTRONICS COOLING, our friend and colleague Bob Simons used his editorial column to inform us that he was resigning his position as an associate technical editor and this issue will be his last. The title of Bob’s editorial was “Looking Back” so it seems fitting to include the term forward in the title of this editorial and to use this space to … [Read more...]
Thermal Facts and Fairy Tales: Heat Sinks, Heat Exchangers and History
As far as history goes, the field of electronics cooling does not have a very long past. A rather quick look through my personal reference material that is strictly geared towards cooling electronics had at the earliest some US Navy documents from the 1950s [1]. Comparing the solution techniques available today to those available then shows that we have both much better tools … [Read more...]
Thermal Facts and Fairytales: Consistency and Accuracy in Simulations
Simulation of temperature fields in electronics is a frequent task for thermal design engineers. Depending on the need and available time, the simulation used to predict temperatures may range from hand calculations to full physics-based numerical simulations. Accurate thermal simulations are always desired but in most instances, even assessing the accuracy level within a … [Read more...]
Technical Data Summary
ElectronicsCooling magazine has been providing a technical data column since 1997 with the intent of providing you, the readers, with pertinent material properties for use in thermal analyses. We have largely covered the most common materials and their associated thermal properties used in electronics packaging and as a result, this column will evolve into additional topics. … [Read more...]
Antifreeze Coolants
Removing waste heat from electronic assemblies using a circulating liquid coolant is a common and effective method with a long and successful history, especially in avionics and data center applications. The choice of coolant depends on many factors including corrosion resistance, cost, thermal properties, regulatory constraints, thermal stability, and environmental temperature … [Read more...]
