Saturated Critical Heat Flux in a Multi-Microchannel Heat Sink Fed by a Split Flow System [PDF]
, 2010 An extensive experimental campaign has been carried out for the measurement of saturated critical heat flux in a multi-microchannel copper heat sink. The heat sink was formed by 29 parallel channels that were 199 μm wide and 756 μm deep.
