ADVANCES IN LIGHTWEIGHT HEAT SINKS
Abstract
Experiments were performed to investigate the thermal performance of a lightweight heat sink made by perforated folded fins. Perforations with circular cross sections were distributed on the lateral side of fins in a staggered configuration. Results were compared against those of a heat sink without perforations. The results are reported as functions of pumping power, in order to provide a better practical insight about the performance of proposed thermal management solution. It was found that despite slightly increase in the thermal resistance, the perforated-finned heat sink in this study is an appropriate thermal management solution in weight sensitive applications.
