Microchannel Heat Sink Based on Boiling Heat Transfer.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1995
Development of a heat sink for future integrated circuit chips has been achieved on the basis of boiling heat transfer in a vertical microchannel. The microchannel was manufactured on a 1.5 mm-thick copper plate by electric discharge machining. The performance of the three kinds of micro-channel heat sinks of which cross sections were 2, 4, and 16 mm ...

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...
