摘要:

从换热器防腐和强化传热的角度出发,对铜板表面进行不同的涂膜处理:聚丙烯酸酯(PA)单双面涂膜、MWCNTs/PA复合材料单双面涂膜和无涂层铜板。通过对流换热实验,研究不同处理条件下的传热系数。结果表明,经PA处理过后的铜板传热系数明显降低。与无涂层铜板相比,单、双面PA处理的铜板传热系数分别下降21.91%和40.00%。经MWCNTs/PA复合材料处理过后的铜板传热系数得到了提高。与无涂层铜板相比,单、双面MWCNTs/PA处理的铜板的传热系数分别提高了16.74%、27.49%。

Abstract:

Different coating treatments were carried out on the surface of copper plate from the point of view of corrosion and heat transfer of heat exchanger:polyacrylate (PA) single-sided and double-sided coating, MWCNTs/PA composite single-sided and double-sided coating, and noncoating copper plate. The heat transfer coefficient under different treatment conditions was studied by convective heat transfer experiment. The results show that the heat transfer coefficient of the copper plate is reduced by 21.91% and 40.00%, respectively, compared with the noncoating copper plate. The heat transfer coefficient of the copper plate treated with MWCNTs/PA composite material is improved, and the heat transfer coefficient of the copper plate treated with single and double sided MWCNTs/PA is improved by 16.74% and 27.49% respectively, compared with the noncoating copper plate.
