Thermal-management techniques take-on the heat
Military and Aerospace Electronics – October, 2022
“The VITA specs suggests applying a constant temperature model,” Weyant says. “That is fine for lower-heat-flux applications and uniform heat loads in a uniform heat sink, but when the overall heat load is driven by a single component, you have a concentrated heat load. By modeling it that way, you could design yourself into a corner and give yourself problems at testing.” Read More…
GUEST BLOG: Boundary conditions for conduction-cooled module simulations
Military Embedded Systems – Greg Hoeschele, Lead Engineer Product Development, September 2022
The VITA 47 standard describes the boundary of the module as a maximum, with different values depending on the class. This is a convenient requirement as it is easy to apply a temperature boundary condition to interface surfaces in an FEA [finite element analysis] model and determine the thermal performance of the card. This is also useful if the heat is evenly spread across the card and the chassis is close to isothermal. The problem is that under certain conditions, this approach will overestimate the thermal performance of the module. Read More…
Small-Scale Biodigesters Are Getting a Big Improvement in Thermal Control
POWERmag.com – Ellie Seber, R&D Engineer II, Advanced Cooling Technologies Inc., August 2022.
As the world looks to increase the usage and production of renewable energy, improving efficiency while lowering energy costs is vital to the adoption of renewable sources. Biodigesters (also known as anaerobic digesters) are a source of renewable energy and act as both an effective waste management solution and a source of biogas, a methane-dense gas that can be used in place of natural gas.

Advanced Cooling Technologies, Inc. (ACT) is transitioning SBIR-developed technology to the MIDS JTRS platform while still in Phase II
Navy SBIR/STTR Success & Spotlight Stories, May 2022. Srujan Rokkam, R&D Manager
The HiK™ (high conductivity) cooling card developed for Navy tactical link electronics was tested and qualified by the two MIDS prime contractors: Viasat, Inc. and Data Link Solutions (DLS, a joint venture of BAE Systems and Collins Aerospace). After testing, it was selected by the primes for use in the MIDS terminal; ACT has received manufacturing orders of $2 million for this hardware. Read More…
