This paper investigates the flow boiling heat transfer in microchannels with the aim of
developing compact cooling systems which can be adapted to miniaturized power components.
Nano- and micro-surface treatments were used as innovative techniques to improve the heat
transfer performance as well as to delay the intermittent dryout. It was observed that the
micro-structured surfaces show significant enhancements (up to 85%) in heat transfer
compared to the smooth surfaces. Especially, using the highly-wetted structured surface,
the intermittent dryout is improved.
