【摘要】 相变流体是一种具有高载热密度的传热工质,但传热性能有待进一步提高。在相变流体中引入能显著提高流体传热性能的纳米颗粒是近年来兴起的研究课题。综述了纳米颗粒在微胶囊相变流体中强化传热性能的研究进展。结合笔者所在实验室的研究成果,介绍了纳米颗粒在相变乳状液方面的传热强化效果,最后提出了下一步工作的重点。更多还原

【Abstract】 Heat transfer performance of phase change fluid needs to be improved although it has high heat carrier density as a heat transfer medium.Adding nano-particles to phase change fluid to enhance the heat transfer is highlighted in recent years.Progress in heat transfer enhancement of microencapsulated phase change material using nano-particles is reviewed.According to authors’ study,heat transfer enhancement of phase change emulsion using nano-particles is introduced as well.Finally,the key points of future research in this field are pointed out.更多还原
