摘要

为提高电子器件双相浸没液冷传热性能，基于分区功能协同的设计理念提出了一种由中心蘑菇装微柱与外围非对称沟槽区组成的复合异构型表面，分别强化气泡成核及脱离与液体回补过程。采用体积分数（VOF）方法的三维瞬态数值模拟，研究复合异构型表面的传热性能以及表面结构对气泡成核及脱离行为的影响，并将其与光滑表面和凹槽表面对比分析。结果表明，在研究的热流密度范围内，复合异构型表面表现出了更优的传热性能，对比光滑表面和凹槽表面的壁面过热度平均降低了28.3%和18.7%，传热系数平均提高了39.5%和22.0%。这归因于其表面结构增加了表面有效传热面积与活化位点密度。此外复合异构型表面的异构结构通过协同设计，同步提升了成核效率，气泡脱离速率与表面再湿润能力。

Abstract

To enhance the heat transfer performance of two-phase immersion cooling for electronic devices

a composite heterogeneous surface was proposed based on a partitioned functional synergy design

consisting of a central mushroom-like (VOF) method was conducted to investigate the heat transfer performance of the composite heterogeneous surface and the effects of surface structures on bubble nucleation and departure behaviors

with comparisons made against smooth and grooved surfaces. The results show that

within the investigated heat flux range

the composite heterogeneous surface exhibits superior heat transfer performance. Compared with the smooth and grooved surfaces

the average wall superheat is reduced by 28.3% and 18.7%

while the heat transfer coefficient is increased by 39.5% and 22.0%

respectively. This enhancement is attributed to the increased effective heat transfer area and higher density of active nucleation sites induced by the surface structure. In addition

the synergistic design of the composite heterogeneous surface simultaneously improves nucleation efficiency

bubble departure rate

and surface rewetting capability.
