用耕作挤出方法,密纹组织的跨 connected finned 与 0.4 公里的厚度在铜脱衣的表面上被形成。结构被使‘ V 成为“在铜脱衣和垂直‘ V 的沟”制作反面上的沟站在一起交叉沟的第一个集合。微毛孔在这些跨 connected 沟的交叉出现,并且微鳍出现在沟穗上。它能因此被定义为‘ p ore-groove-fin' 结构。更好的 ‘p ore-groove-fin'结构能在条件下面被获得工具边倾斜角度(χγ)是 45 °,主要挤出角度( γo )和次要的挤出角度( γ′o )是 30 ′,两主要形成角度(β)和次要的形成角度(β′)是 10 °,耕作挤出深度( fd )是 0.32 公里和沟沥青是表面 A 和 B 上的 0.4 公里。沟 A 的形成的包括的角度是 70 °,并且沟深度是 0.3 公里,当相反的垂直的沟 B 的包括的角度是有 0.35 公里的沟深度的 20 °时。获得的鳍高度是 0.15 公里,椭圆的毛孔长度是 0.2 公里,宽度是 0.05 公里。实验证明 fd 在微毛孔的形成上有最大的影响。当表面 A (fdA ) 上的耕作挤出深度到达一个临界数值时,膨胀出现在相反的表面 B 上。表面 B (fdB ) 上的耕作挤出深度在鳍结构的重新生长上有大影响。
Using ploughing-extrusion method, a cross-connected finned micro-grooves structure was formed on the surface of copper strips with thickness of 0.4 mm. The structure was fabricated by making 'W-grooves in copper strips and perpendicular 'V'-grooves on the opposite side that intersect the first set of grooves. Micro pores appear at the intersection of these cross-connected grooves, and micro fins appear on the groove fringes. So it can be defined as 'pore-groove-fin' structure. The preferable 'pore-groove-fin' structure can be obtained under the condition that the tool edge inclination angle (Xy) is 45°, both the major extrusion angle (γo) and the minor extrusion angle (70) are 30°, both the major formation angle (β) and the minor formation angle (β') are 10°, the ploughing-extrusion depth (γ°) is 0.32 mm and the groove pitch is 0.4 mm on surfaces A and B. The formed included angle of groove A is 70°, and the groove depth is 0.3 mm, while the included angle of opposite perpendicular groove B is 20° with the groove depth of 0.35 mm. The obtained fin height is 0.15 mm, the elliptical pore length is 0.2 mm and the width is 0.05 mm. Experiments show that fd has the greatest influence on the formation of micro pores. Bulges appear on the opposite surface B when the ploughing-extrusion depth on surface A (fdA) reaches a critical value. The ploughing-extrusion depth on surface B (fdB) has great influence on the re-growth of fin structure.
