The optimal shape of a Plate-Pin-Fin Heat Sink with Perforations and Splitters (PPFHS-PS) is designed in this work using the software package CFD-ACE+ and the Levenberg-Marquardt method (LMM) to determine the maximum thermal performance factor η under a fixed fin volume constraint. In the present work, the implementations of perforations and splitters on a pin fin are examined, and the diameter of the pin, the perforated diameter of the pin and the length of the splitter are considered as the design variables. The hydrothermal performances of a Plate-Pin-Fin Heat Sink (PPFHS), a Plate-Pin-Fin Heat Sink with Perforations (PPFHS–P) and a Plate-Pin-Fin Heat Sink with Splitters (PPFHS–S) are compared. It is found that a great enhancement in the thermal performance factor can be resulted for the PPFHS-PS. The numerical design cases indicated that when considering an incoming velocity of 5.0 m/s, the percentage improvements of η for the PPFHS-P, PPFHS-S and design #2 PPFHS-PS are 4.9%, 5.2% and 10.1% higher than that of the original PPFHS. It indicates that the individual contribution of thermal performance factor improvement of the PPFHS-P and PPFHS-S can be added if the perforations and splitters are utilized simultaneously in the PPFHS-PS design. Finally, experimental verifications are conducted on the manufactured PPFHS-P, PPFHS-S and design #2 PPFHS-PS modules, and the measurement results of the temperature distributions and pressure drops indicate that the experimental data matched quite well with the computational data for those heat sinks.
