微通道冷却是解决高热流密度散热问题最有效的技术之一,具有传热效率高、热阻低、结构紧凑等优点,但同时存在压降增加的问题。微通道的结构是影响其流动与传热性能的重要因素。针对该问题,简述了国内外对单相液冷微通道散热器在结构设计方面的研究进展,分为通道几何结构、扰流结构、针肋结构、多层结构、仿生结构和复合强化结构。结合各结构强化传热的原理,分析其在传热系数、压降、综合性能、均温性等方面的优缺点,并对微通道散热器常用的基体材料与加工方法进行了成本分析。基于上述总结与介绍,从应用角度展望了微通道散热器的前景与发展方向,指出复合结构的应用、仿真与实验的结合、材料学与加工技术的进步以及学科交叉是今后结构研究的重点。
Microchannel cooling
with its high heat transfer efficiency
low thermal resistance
and light weight advantages
is one of the most effective technologies for solving the problem of heat dissipation with high heat flux; however
it faces the issue of increased pressure drop. The microchannel structure determines the thermal-hydraulic performance. This study describes the research progress on single-phase liquid-cooled microchannel heat sinks in terms of domestic and international structural design to address this problem. Among them
single-phase heat dissipation structures are divided into variable cross-sectionals
flow disruption
pin-fin
double-layered
bionic
and hybrid-reinforced structures. The advantages and disadvantages of the heat transfer coefficient
pressure drop
comprehensive performance
and temperature uniformity were analyzed based on the principle of enhancing heat transfer in various structures. A cost analysis of the commonly used matrix materials and processing methods for microchannel heat sinks was conducted. Finally
we provided the prospect and development direction of microchannel heat sinks from an application perspective. The application of composite structures
integration of simulation and experimentation
advances in material science and processing technology
and the nexus of disciplines are noted as the focus of future structural research.
