A GM article explaining the Chevrolet Volt’s cooling/heating systems notes that the power electronics coolant loop is designed to insure the main underhood electronics do not overheat during use. It is essential that the heat developed by the power inverter module and the plug-in battery charger while operating the Volt or when plugged in be dissipated in order to prevent … [Read more...]

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...]
Open Bath Immersion Cooling In Data Centers: A New Twist On An Old Idea
Phil Tuma 3M Company, St. Paul, Minnesota The inefficiencies of legacy datacenter air cooling schemes are by now well known. New “Free Air” cooling technologies in which air is introduced to the racks in a facility or container and confined in hot and cold plena probably represent the pinnacle of air cooling efficiency, at least where climate permits them. However, development … [Read more...]
