Eco-design of heat sinks based on CAD/CAE techniques
Journal Title: Proceedings in Manufacturing Systems - Year 2017, Vol 12, Issue 1
Abstract
In the context of industry 4.0, the overall performance of manufacturing systems largely depends on the performance of embedded electronics. Such devices are responsible for conditioning information between machines and equipment such that desired input / output actions can be achieved. To be competitive, manufacturers are harnessing their products by performing several design decision loops based on the product’s overall performance during their lifecycle. Even so, due to new developing technologies such products become soon obsolete. Thus, high demands for new products cause large streams of electronic waste. To overcome this issue new design principles have emerged. Eco design together with the development of sustainable technologies help manufacturers to conceive their products in order to meet both environmental and customer requirements. Such interdisciplinary approaches maintain a balance between environmental costs and material necessities having a major impact on all lifecycle stages of a product. As a consequence, landfill is lowered and more value is added to the final product. Valuable knowledge is also achieved and transferred to new products by means of guidelines, check list and software extensions. Power electronics embedded in manufacturing systems requires proper thermal design to withstand high temperatures and perform according to the design specifications. Heat sinks are one of the most common devices used for cooling electronics. This paper deals with the lifecycle stages of heat sinks, discussing about the traditional CAD/CAE design tools extended to meet eco-design criteria. A case study illustrates the given concepts for the design of a variable speed drive passive cooler.
