Abstract
As a heat dissipation device with high heat dissipation efficiency,microchannel heat sinks are widely used in the field of chip heat dissipation.The structure of the microchannel heat sink was improved,and numerical simulations were carried out on traditional microchannel heat sinks,elliptical ribbed microchannel heat sinks,rectangular side-ribbed microchannel heat sinks and new microchannel heat sinks composed of the two.The flow performance of the heat sink was evaluated using fluid-solid coupling wall area,pressure drop and Darcy friction factor,and the heat transfer performance of the heat sink was evaluated using thermal resistance and Nusselt number.Finally,the comprehensive performance evaluation factor of the heat sink was used to evaluate the flow and heat transfer performance of the above four heat sinks.The results show that at low flow rates,the elliptical needle fin microchannel heat sink has the best comprehensive performance,and at high flow rates,the new microchannel heat sink combining elliptical needle fins and rectangular side ribs has the best comprehensive performance.关键词
