How to cool small form factor electronics?
Systems are getting smaller and CPU are always more powerful!
When the processing capabilities of a system increase, the power consumption increases too. Therefore it increase the amount of heat produced. That’s why sensitive electronics require adequate cooling to keep a consistent operation.
Fanless cooling could be an option for a many reasons including a better iP protection, the ability to shield sensitive electronics from air contaminants, reduced noise of operation, and a better reliability.
Unfortunately, the performance of conduction cooling is limited. Engineers requiring fanless cooling have had 2 options, opt for a very expensive liquid cooling or heat pipe solutions, or they can limit the performance of their boards.
This whitepaper will explain the factors that limit conduction cooling performance, introduce manufacterers innovative conduction cooling products, and finally to review the performance of the various solutions presented.
