Cooling Update and Trends

Electronics are Getting Hotter – How are We Going to Cool Them?
Chris A. Ciufo

We’re fast approaching the practical limits of cooling leading-edge COTS electronics. More efficiency is possible, but soon radical new thinking is going to be required.

Liquid Cooling: Today’s Solution for Tomorrow’s Military COTS Enclosures
Colin Davies, Product Manager, Systems and Chassis, Radstone Technology

Moving from 15W per slot to 60W per slot, and 600W per ATR box requires liquid cooling techniques.

Thermal Simulation Optimizes Chassis Cooling
Gary Hanson, Project Engineer, Elma Electronic

Moving from 15W per slot to 60W per slot, and 600W per ATR box requires liquid cooling techniques.

Mezzanine Card Assemblies: Where is All That Cooling Air Going?
Michael R. Palis and Robert C. Sullivan, Hybricon

Mezzanine modules such as CMC/PMC, and soon XMC, dominate military single board computers and carrier cards. But merely blowing lots of air at them doesn’t necessarily keep them cool. The reasons and recommendations may be surprising.

Comparison of Airflow Testing Methods
Jack Berenholz PE, Consultant, John Alba, Quest Engineering Solutions

There’s a big difference between airflow tests conducted with air in feet-per-minute and cubic feet per minute. Choose the wrong test and system reliability may be at stake as temperatures climb.
