A tour of VITA AFT cooling standards in 2023 - Military Embedded Systems
For critical and intelligent deployed embedded modules, air-flow-through (AFT) cooling describes an approach that brings the coolant much closer to heat-generating electronics than standard conduction-cooled approaches. As a result, compared to conduction cooling, AFT increases the amount of power that can be cooled and decreases device temperatures.
