摘要

•Open-ring pin fin microchannels (ORPFM) were developed for advanced microchannel heat sinks.•Both inline and staggered ORPFM presented a small wall superheat for ONB.•Inline ORPFM augmented boiling heat transfer, reduced pressure drop compared to staggered ones.•Inline ORPFM mitigated two-phase flow instabilities compared to staggered ones.
