显著增加微通道内两种不互溶液体的分段流动的努塞特数:实验研究
Increasingly smaller electronics requires improvement in performance of cooling systems to keep it operatingreliably. We present herein a novel experimental study of convective heat transfer in serpentinemicrochannels with segmented liquid–liquid emulsions. It is demonstrated that this concept yields significantNusselt number enhancement in microchannel heat sinks compared to that obtained using singlephase liquid cooling. Laser Induced Fluorescence (LIF) is employed to measure temperature of the coolantwith and without droplets, and micro-PIV is used to determine velocity field. For the segmented flow, upto four-fold increase of the Nusselt number was observed compared to pure water flow.
