Multidisciplinary and multiscale design optimization of additively manufactured high efficiency passive heat sinks for advanced cooling of electronic systems

通用动力任务系统加拿大公司（GDMS-C）是一家位于安大略省的创新技术公司，**为国防和安全部门提供先进的电子系统和领先的硬件。**在高性能电子系统中使用的很大一部分功率被转换为热量，**需要一个可靠和高效的热管理系统。虽然主动冷却方法**，如强制空气和泵送液体冷却，可能比被动散热器提供更好的性能，但**它们的代价是更高的成本和能耗，噪音和运行期间机械故障的风险增加**。相比之下，低风险的被动冷却系统在各种应用中对电子设备的冷却能力已经达到了极限。很明显，在不久的将来，被动散热器的增量改进预计将不足以满足高性能电子系统发展的快速增长。**采用当前最先进的被动冷却技术，GDMS-C面临着寻找更高效率的被动加热模块以满足其电子系统设计要求的挑战。通过这个项目，**GDMS-C有兴趣建立一个完全集成的平台，用于多学科和多尺度的增材制造高效被动散热器的设计**优化，用于高性能的电子**系统。这一发展将给公司设计自由，拥有一个内部平台，将**集成到他们的整体开发过程中，以设计定制的被动式散热器，完美地为**各种电子产品的不同功能要求量身定制。

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.
