Optimization of Heat Transfer Performance of Microchannel with Concave Cavity-Convex Rib Composite Structure and Research on Acoustic Wave Regulation Mechanism
摘要
Abstract
An effective solution for the thermal management of high-power-density devices is the use of microchannel heat dissipation.An optimization strategy based on the coupled structure of concave cavity and convex rib is proposed to design three types of two-dimensional microchannels.By intensifying flow turbulence,the overall heat transfer efficiency is enhanced while controlling pressure drop,and compared with that of conventional two-dimensional smooth microchannel(SMC).Through numerical simulations,the flow field characteristics,heat transfer mechanisms,and thermodynamic performance of different microchannels are systematically investigated.Results indicate that the misaligned semi-circular cavity rib microchannel(MC-SCSR)exhibits the most optimal overall heat transfer efficiency.Further research results on active acoustic field cooling coupling show that acoustic wave disturbances produce a synergistic effect with the MC-SCSR structure,resulting in an average increase of 15.3％in the comprehensive performance factor compared to scenarios without acoustic wave disturbances.关键词
