Calculation Corner: Thermal Interactions Between High-Power Packages and Heat Sinks, Part 1
Bruce Guenin, PhD Associate Technical Editor The need to accommodate increasing chip power has led to improved package and heat sink designs having much lower thermal resistance values than previously. This has led to challenges in accurately calculating the thermal performance of the package and heat sink as an integral unit on the basis of thermal resistance measurements … [Read more...]
Thermal Facts and Fairy Tales: Fixed Temperature and Infinite Heatsinking
In keeping with the name of this column, the fact worth reminding is that a fixed temperature boundary condition in a thermal simulation represents an infinite heat sink. The systems that thermal engineers model and simulate have boundaries and thus require some type of specification, usually known as boundary conditions. Related to the other part of the name of this column, … [Read more...]
SynJet Technology Helps Europe Go Green
Nuventix, Inc. announced it is seeing significant adoption of its SynJet technology across Europe, most notably in store installations of the region’s largest retailer.
