| الوصف: | Increasing the power density of electronic components requires more efficient thermal management. Thermal problems are even becoming the major concern of designers for the conception these components. Phase Change Material (PCM) based heat sinks are widely used in several industrial applications particularly in mechatronics field. These passive cooling techniques allow better thermal management of electronic components. Recently, researchers aim to find an optimaldesign of these systems in order to improve their efficiency. However, uncertainties are not considered for the majority of these studies. This study aims to propose a new methodology that leads to proposing an optimal model of a PCM-based cooling systems considering uncertainties. The Deterministic Design Optimization approach (DDO) provides an optimal design, but its relibility level is not respected. To this end, Reliability-Based Design Optimization (RBDO) techniques are then required. These approaches aim to find a reliable design with an optimal cost by considering uncertainties of the studied model. Classical RBDO methods have been applied only in linear problems and in specific non-linear ones. This study presents an extension of these methods by considering the nonlinearity of the problem. The last part of this thesis consists in studying a problem of multiobjective reliabilitybased design optimization of PCM-based heat sinks. To remedy the complexity of these systems considering uncertainties, surrogate models are then applied. These methods lead to construct an approximate model, which ensures both precision and efficiency of the model. In this study, we propose a new methodology, called MORBDO-RHM, which consists in combining the Robust Hybrid Method (RHM) with the Constrained Non-dominated Sorting Genetic Algorithm (C-NSGA-II). The efficiency of the proposed approach is then verified for a PCM-based thermal storage unit. ; L'augmentation de la densité de puissance des composants électroniques nécessite une gestion thermique plus efficace. ... |
