The reduction in size of modern electronic components and the accompanying reduction in size of computer casings requires optimized thermal designs for reliable electronic systems. Cooling problems related to electronic systems can be divided into the cooling of components mounted on heat sinks, components mounted on boards and environmental-level analysis. This paper will concentrate on the cooling of components with heat sinks using a finite difference simulation of the heat transfer in typical heat sink configurations. Various heat sinks were simulated to obtain the effect of the influencing parameters on the heat transfer at the boundaries. The simulated results were compared with experimental values over a range of heat dissipation in each type of heat sink. From the experiments, improved heat transfer models were developed at the boundaries to compensate for the influencing parameters such as heat sink orientation relative to gravity and by-pass air flow. It can be concluded from the results that three-dimensional simulations have distinct advantages over traditional design graphs to analyze the performance of heat sinks and should be common practice for the electronics design engineer.read more

TL;DR: In this paper, the authors explore the porous block paradigm based on replacing an actual heat sink by the volume of fluid that once enveloped the fins, achieving thermal equivalence by increasing the thermal conductivity of the lumped fluid above the base plate until the thermal resistance of the actual heat sinks is matched.

Automated fault tolerance augmentation in model-driven engineering for CPS
TL;DR: This paper proposes a general framework which allows system designers to decouple functional and non- functional concerns, and express non-functional properties at design time using domain-specific languages, and in the spirit of generative programming, functional models are automatically "augmented" with dependability mechanisms.
