TL;DR: In this paper, a structured microchannel with micro cone pin fin was developed for the utilizations in advanced microchannel heat sinks to cool high heat-flux devices, which provided lots of stable nucleation sites by producing lots of tiny reentrant cavities and introduced significant wicking effects to maintain the liquid rewetting and hinder the local dry-out.

TL;DR: In this article, four types of staggered micro pin fin with different cross-section shapes, i.e., square, circular, diamond and streamline, were fabricated by a laser micromilling method, and constructed for heat sinks cooling systems.

TL;DR: In this article, a reentrant microchannels (REEM) was developed for heat sink cooling and compared with a conventional rectangular microchannel (RECM) with the same hydraulic diameter to explore the microchannel shape effects and feasibility of enhancement.

TL;DR: In this paper, a pin fin-interconnected reentrant microchannels (PFIRM) is proposed and developed for microchannel heat sinks cooling systems to combine both merits of reentrants cavities and micro pin fins in heat transfer enhancement.

TL;DR: In this article, a reentrant porous microchannels (RPM) with Ω-shaped configurations was developed and tested in heat sink cooling systems, and the results showed that the RPM trigger the onset of nucleate boiling (ONB) at small wall superheat under all the ethanol boiling cases due to the significant increase of nucleation sites.
