Increasingly smaller electronics requires improvement in performance of coo領(lǐng) systems to keep it operating reliably. We present herein a novel experimental study of convective heat transfer in serpentine microchannels with segmented liquidliquid emulsions. It is demonstrated that this concept yields significant Nusselt number enhancement in microchannel heat sinks compared to that obtained using single phase liquid coo領(lǐng). Laser Induced Fluorescence (LIF) is employed to measure temperature of the coolant with and without droplets, and micro-PIV is used to determine velocity field. For the segmented flow, up to four-fold increase of the Nusselt number was observed compared to pure water flow. 顯微粒子成像測速系統(tǒng)(Micro PIV) Imager intense PIV相機(jī) 用于粒子成像測速(PIV)的熒光示蹤粒子
