Developing convective heat transfer in deep rectangular microchannels

摘要

Experimental results have been obtained for single-phase forced convection in deep rectangular microchannels. Two configu- rations were tested, a single channel system and a multiple channel system. The two systems are identical except for the lack of extended surfaces in the single channel system. In the case of the multiple channel system the channels are 251 μm wide and the channels walls are 119 μm thick. In both systems the channels are approximately 1000 μm deep and define a projected area of 2.5 cm × 2.5 cm.
