Fanless Cooling for Embedded Applications

Executive Summary
Embedded market opportunities for Intel® architecture components exist in Point-Of-Sale Terminals, Digital Signage, and Digital Security Surveillance market segments to name a few. When selecting Intel® architecture, several key metrics customers pay attention to include performance/watt, Thermal Design Power (TDP), total cost of ownership, and reliability. The Embedded Computing Group (ECG) offers scalability with Intel® architecture products ranging from full power (35W and up) to low power (10W~15W) to ultra-low power (~5W) Intel® architecture system solutions to address these market segments and requirements. The objective of this white paper is to provide system designers a reference fanless cooling solution for a Point-Of-Sale application.

Why a fanless solution? Higher reliability, lower cost, and lower power applications are among the primary selection criteria when considering whether to design a system with or without a fan. Other considerations include smaller form factor requirements, acoustic constraints, and specific working environments. The majority of “off the shelf” thermal solutions are not suitable for adoption in fanless applications; and often experience overheating in the system and/or an over designed thermal solution.

This paper will provide emphasis on component level natural convection heatsink characterization and optimization followed by a first level system approximation utilizing a CFD simulation.
