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...]
Beer Fridge – A Case Study in Thermal Design. Part 1 – A Gift
My boss, Roland, relocated from Germany to the UK a couple of years ago and has taken to life in England with alacrity. As a gift for the Mechanical Analysis product development department (Hampton Court) he bought a little fridge which has been busy ever since cooling the beer in it that everyone has been too polite to drink. A few weeks ago it stopped working. Some … [Read more...]
Multidirectional Mini Blower for Air-Flow Applications
Providing a solution for customized air-flow applications, JARO’s new JRB2235 series rotates at 8500 RPMs and produces a powerful 1.2 CFM of super-cooled air (with a static pressure of .122" of H2O). Operating voltage is 4.0V to 5.5VDC. The availability of single or dual unit configurations provides customers with the unique ability to select the precise direction(s) of … [Read more...]
