Abstract

Experiment results have been obtained for single-phase laminar forced convection in rectangular microchannels. Microchannel heat sinks (having a total projected channel area of 1.0 cm by 1.0 cm) with 64 channels of width 54 μm and height 215 μm each were built and tested. Tests were performed with deionized water as the cooling fluid, where the liquid flow rate ranged from 0.5 cc/s to 10 cc/s. Results of the system performances were presented in terms of overall pressure drop and local thermal resistance. Also, the associated convective heat transfer was reported in terms of the friction factor and the Nusselt number. The experimentally obtained results agree reasonably well with the classical developing channel flow theory.
