摘　　要：单一的传热强化技术对于传热性能和传热效率的提升有限,大力发展复合强化传热技术对提高资源利用率、节能减排具有重要意义。制冷剂作为一种应用广泛的热力学介质,其物理性质很大程度上会影响制冷系统的能量传输效果。基于制冷系统小型化、轻量化及节能高效换热的发展趋势,制冷剂复合强化传热可以有效改善系统的制冷能效,近年来受到专家学者的广泛关注。综述了制冷剂复合强化流动沸腾传热的最新研究进展,分别从纳米颗粒、泡沫金属、外场(超声/磁场/电场)以及绿色混合制冷剂4个角度进行系统的讨论和总结,指出制冷剂复合强化技术应用的前景和存在的问题,展望了多场协同作用下的纳米颗粒-泡沫金属-制冷剂复合强化传热是今后的重点发展方向,可为建立新型的多元制冷剂复合强化体系提供一定的思路和参考。Improvements in heat transfer performance and efficiency through a single heat transfer enhancement technology are limited.Hence,composite-enhanced heat transfer technologies must be developed to improve resource utilization rates and reduce energy consumption and carbon emissions.Refrigerants exhibit physical properties that significantly affect the energy transport in refrigeration systems.Based on the development trend of refrigeration systems characterized by miniaturization,reduced weight,energy savings,and efficient heat transfer,refrigerant composite-enhanced heat transfer can effectively improve the energy efficiency of refrigeration systems,which has been widely studied in recent years.This work summarizes the latest research progress in composite-enhanced flow boiling heat transfer for refrigerants,focusing on nanoparticles,metal foam,external field(ultrasonic/magnetic field/electric field),and environmentally friendly refrigerant mixtures.It also highlights the prospects and existing problems in the application of multi-field synergy and nanoparticle-metal-foam-refrigerant composite-enhanced heat transfer as a future research direction.The review provides insights and references for establishing a new multi-element refrigerant composite-enhanced system.
