Research on Manufacturing and Capillary Performance of Porous Groove Composite Wick

本文通过采用电化学沉积方法,在铜沟槽管内表面制备得到多孔槽复合吸液芯。利用SEM对复合吸液芯进行微观形貌分析,并搭建吸液芯毛细性能测试平台,探究了电解液溶度对复合吸液芯毛细性能的影响。结果表明,电化学沉积制备的复合吸液芯毛细性能均优于沟槽吸液芯,其中电解液溶度为0.03mol/L时,复合吸液芯的毛细性能最好,毛细上升高度为46.5 mm,与沟槽吸液芯相比,毛细上升高度提升了52.3%。

In this paper,a porous groove composite wick is fabricated on the inner surface of a copper grooved tube by using an electrochemical deposition method.SEM was used to analyze the morphology of the composite wick,and a test platform for the capillary performance of the wick was built,to explore the influence of electrolyte solubility on the capillary performance of the composite wick.The results show that the capillary performance of the composite wick fabricated by electrochemical deposition is better than that of the groove wick.When the electrolyte solubility is 0.03mol/L,the capillary performance of the composite wick is the best,and the capillary rise height is 46.5 mm,compared with the grooved wick,the capillary rise height is increased by 52.3%.
