摘要/Abstract

摘要： 采用微通道散热是高功率密度器件热管理的有效解决方案。基于凹腔-凸肋耦合结构提出一种优化策略，设计3种二维微通道。通过增强流动扰动，在控制压降的同时提升综合换热效能，并与传统二维光滑微通道（SMC）对比。通过数值模拟，系统研究不同微通道的流场特性、传热机制及热力学性能。结果表明，错列式半圆腔肋微通道（MC-SCSR）的综合换热效能最优。进一步的声场主动散热耦合研究结果表明，声波扰动与MC-SCSR结构产生协同效应，综合性能较无声波扰动的工况平均提高15.3%。

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.
