本文通过实验和数值模拟研究了不同形状微肋微流控热沉的传热和摩擦特性，矩形、三角形和半圆形肋骨。利用表面微加工技术在微流控通道侧壁上制作微肋，并将其作为微流控热沉的散热器，提高微流控热沉的传热效率。结果表明，利用微肋提供了更好的传热速率，但也增加了微通道的压降惩罚。此外，微通道的传热和摩擦特性受到肋形状的强烈影响。相比之下，三角形肋微通道具有最高的努塞尔数和摩擦系数的三种肋类型。
This paper experimentally and numerically investigated the heat transfer and friction characteristics of microfluidic heat sinks with variously-shaped micro-ribs, i.e., rectangular, triangular and semicircular ribs. The micro-ribs were fabricated on the sidewalls of microfluidic channels by a surface-micromachining micro-electro-mechanical system (MEMS) process and used as turbulators to improve the heat transfer rate of the microfluidic heat sink. The results indicate that the utilizing of micro-ribs provides a better heat transfer rate, but also increases the pressure drop penalty for microchannels. Furthermore, the heat transfer and friction characteristics of the microchannels are strongly affected by the rib shape. In comparison, the triangular ribbed microchannel possesses the highest Nusselt number and friction factor among the three rib types.
