General Dynamics Mission SystemsCanada (GDMS-C) is an Ontario based innovative technology company,**providing advanced electronic systems with leading-edge hardware for the defense and security sectors.**Significant fraction of the power employed in high performance electronic systems is converted into heat,**necessitating the need for a reliable and efficient thermal management system. While active cooling methods**such as forced air and pumped liquid cooling, may provide better performance compared to passive heat sinks,**they come at the expense of higher cost and energy consumption, noise and increased risk of mechanical failure**during operation. In contrast, low-risk passive cooling systems are reaching their limits in terms of cooling**capacity for electronic devices in various applications. It is evident that incremental improvements in passive heat**sinks are projected to be insufficient to meet the fast paced growth in the development of high performance**electronic systems in the near future.**With the current state-of-the-art passive cooling technology, GDMS-C is faced with the challenge of finding higher**efficiency passive heat modules that meet their electronic systems design requirements. Through this project,**GDMS-C is interested in building a fully integrated platform for the multidisciplinary and multiscale design**optimization of additively manufactured high efficiency passive heat sinks for superior performance electronic**systems.**This development will give the company the design freedom by having an in-house platform that will be**integrated into their overall development process to design custom built passive heat sinks, perfectly tailored for**the different functional requirements of their wide array of electronic products.
