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.

• 本研究通过实验量化了不同构型的入口限流装置（inlet restrictors）对流动沸腾微通道散热器传热性能及压降的影响。• 在低质量通量下，多入口限流装置（Multiple IRs）对临界热流密度（CHF）的增强效果最优；而在高质量通量下，单入口限流装置（1IR）的表现最佳。• 在较低质量流量下，多开口入口限流装置的工况通常优于单开口入口限流装置（如CHF更高）。• 最优构型通过最大化传热性能（如CHF增强效果）并最小化压降损失获得。
