碩士 / 國立成功大學 / 系統及船舶機電工程學系 / 106 / A three-dimensional inverse design problem is examined in this thesis using a general purpose commercial package (CFD-ACE+) and the Levenberg-Marquardt Method (LMM) to estimate the optimum perforation diameters and shape for perforated pin fins with different design variables.
Based on the literature [18], this study consists of four cases. The objective of this thesis is to find the best shape design with a fixed volume condition for minimizing the temperature difference between base plate averaged temperature and ambient temperature, ΔT. Each case has three shape parameters, the perforation diameter, the pin diameter, and the pin height in the optimization design. The numerical simulation results show that the temperature difference between base and the environment, ΔT, of the original design heat sink module can be further reduced in the optimum heat sink modules by considering pin height and pin diameter as the design variables.
Finally, the experiments are performed to show the validity of the present design results and the temperature distributions are very similar between the experimental and numerical data. Results show that the Levenberg-Marquardt Method (LMM) can help us to find the optimum heat sink design for the best heat dissipation efficiently.
