Air-cooled chassis play a pivotal role in contemporary engineering practices to meet evolving size, weight and power (SWaP) critical requirements. These integrated enclosures or chassis are engineered with advanced thermal management technologies, addressing the challenges posed by stringent application requirements.
Popular fabrication methods include aluminum die casting, sheet metal bending, welding, dip brazing and vacuum brazing as well as integrating two phase or graphite heat spreading technologies such as heat pipes and k-Core® encapsulated graphite.
Creative engineers are more frequently incorporating heat spreading, thermal joints and other technologies into enclosure designs so that these enclosures and chassis act as both a structural and thermal solution to replace traditional, mechanical-only enclosures.
Air-cooled chassis and enclosures integrate air cooling features like heat sinks, heat spreaders or fins acting as both mechanical protection and thermal management solutions.
Extend the thermal performance of traditional die cast enclosures by embedding heat spreading components like heat pipes, encapsulated graphite or vapor chambers.
