Abstract

Abstract: The Critical Heat Flux (CHF) in microchannel flow boiling is a key parameter limiting the heat dissipation performance of high-heat-flux devices. Enhancing CHF is crucial for the safe operation of electronic devices, new energy batteries, and aerospace thermal management systems. This article reviews research progress on the influencing mechanisms of CHF in microchannel flow boiling. It focuses on analyzing four typical CHF enhancement techniques: surface modification (porous structures, microstructured surfaces), working fluid modification (nanofluids, zeotropic mixtures), microchannel structural optimization (grooved walls, bidirectional counter-flow designs), and flow control (microfluidic transistors, micropin-fin fences). A comparative analysis of the applicability characteristics of different methods is provided, offering valuable references for mechanistic research and technological development of CHF in microchannel flow boiling.

Key words: microchannel, flow boiling, Critical Heat Flux (CHF), high-heat-flux devices

摘要： 微通道流动沸腾临界热流密度(CHF)是限制高热流密度设备散热性能的关键参数,它的提升对电子器件、新能源电池及航天热管理系统的安全运行至关重要。文中对微通道流动沸腾CHF影响机制研究进展作了评述,重点研讨分析4种典型的CHF提升技术:表面改性(多孔结构、微结构表面)、工质改性(纳米流体、非共沸混合工质)、微通道结构优化(槽壁结构、双向逆流设计)以及流动控制(微流体晶体管、微针翅栅栏)。对比分析了不同方法的适用特性,为微通道流动沸腾CHF的机理研究与技术开发提供了一定参考。
