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 ...
