ABSTRACT Flow boiling experiments were conducted in a staggered array micro pin fin channel heat sink with deionized water for two-phase pressure drop and boiling heat transfer at constant heat flux. Micro pin fin is a diameter of 400 μm, height of 700 μm and spacing of 300 μm on copper heat sink. From the experimental results, at a vapor quality up to 0.043, the boiling heat transfer found to decrease as the vapor quality increased. The heat transfer coefficient is dependent on the mass flux and the pressure drop increased with the increase in mass flux.

恒定热流下微针翅通道散热器两相压降及流动沸腾传热实验研究

摘要 流动沸腾实验在具有去离子水的交错阵列微针翅片通道散热器中进行，用于在恒定热通量下进行两相压降和沸腾传热。Micro pin fin是直径400 μm、高度700 μm、间距300 μm的铜散热片。从实验结果来看，在蒸汽质量高达 0.043 时，发现沸腾传热随着蒸汽质量的增加而降低。传热系数取决于质量流量，压降随着质量流量的增加而增加。
