Data for: An Experimental Investigation of the Effect of Multiple Inlet Restrictors on the Heat Transfer and Pressure Drop in a Flow Boiling Microchannel Heat Sink

• In this study, experimental investigations were performed to quantify the effect of different configurations of inlet restrictors on the heat transfer performance and pressure drop in a flow boiling microchannel heat sink.
• Multiple IRs performs best in CHF enhancement at low mass flux, and the 1IR case performs best at high mass flux.
• For lower mass flow rates, cases with multiple-opening inlet restrictors generally work better (e.g., higher CHF) than cases with the single-opening inlet restrictor.
• The optimum configuration was obtained by maximizing the heat transfer performance (e.g., in terms of CHF enhancement) and minimizing the pressure drop penalties.
