新型翅片蒸发器换热性能对比分析研究

Comparative Analysis and Research on Heat Transfer Performance of New Finned Evaporator

通过分析蒸发器部件结构安装技术现状,在常规翅片蒸发器设计方案基础上,设计出涂覆石墨烯材料的翅片蒸发器并完成单体换热性能对比验证。结果表明,通过在翅片蒸发器表面涂覆适量厚度的石墨烯涂层、均匀性达到设计要求的条件下,涂覆石墨烯的翅片蒸发器换热量较原状态的换热量提升至少20 %,可以作为翅片蒸发器改进设计的一个研究方向。

According to the analysis of current evaporator component structure installation technology,the finned evaporator of graphene materials is designed on the basis of conventional finned evaporator design scheme and the contrast verification of heat transfer performance for the monomer is completed.The results show that the heat exchanging quantity of finned evaporator with graphene layer increases at least 20%compared to the original state,can be used as a research direction of the finned evaporator improved design.
