Rice-inspired oriented copper fiber wick with excellent capillary performance for ultra-thin vapor chamber

Effect of Copper Content on the Microstructure and Properties of the Sintered Porous Aluminum Wick

“…with the samples containing 1 wt.%, 3 wt.%, and 5 wt.% Cu reaching 110 mm before 80 s, 10 mm higher compared to the fiber capillary wicks prepared by Wang [10]. Figure 12b shows the relationship between the capillary characteristic parameter and Cu content, which revealed an overall decreasing trend.…”

“…The fluid's rising height then reached a certain value, and the rising speed was gradually reduced due to the influence of gravity. All samples reached a fluid height of 110 mm before 120 s, with the samples containing 1 wt.%, 3 wt.%, and 5 wt.% Cu reaching 110 mm before 80 s, 10 mm higher compared to the fiber capillary wicks prepared by Wang [10]. Figure 12b shows the relationship between the capillary characteristic parameter and Cu content, which revealed an overall decreasing trend.…”

“…The performance of a capillary wick depends on many factors, such as materials, porous structures, preparation method, etc. [7][8][9][10]. Commonly available materials for wicks include copper, aluminum, nickel, and carbon fiber [11][12][13][14].…”
