Coupling PCM-based Heat Sinks finite elements model for mechatronic devices with Design Optimization procedure

Abstract

An efficient strategy is presented in the recent study. This strategy leads to determine the best design based on thermal management system of phase change material (PCM) for cooling electronic devices. The phase change material is filled inside the heat sink made of Aluminum. Salt Hydrate is used as PCM to keep the temperature of such devices below the critical temperature by absorbing the thermal energy released by electronic components. In the last few decades, designers try to find the optimal design of such a structure. Then, many methods have been developed to reach this goal. Deterministic Design Optimization (DDO) used proposes to minimize an objective function based on physical constrain (thermal constrain). In fact, the maximum temperature of the electronic device should not reach the critical one, to guarantee its best performance. The proposed strategy is programmed using MATLAB codes which is coupled with the finite element software Ansys. Its efficiency is then verified using a numerical application of PCM based heat sink.
