(ZH) 散热片、热交换器以及金属构件
Abstract
(EN)
A fin (50) includes a metal base (18Xr) and a porous anodized layer (14) formed on the metal base. A surface of the porous anodized layer has a submicron-order uneven structure, the uneven structure includes a plurality of recessed portions (14Ap) (14Bp) whose two-dimensional size viewed in a normal direction of the surface is more than 100 nm and less than 500 nm. The uneven structure comprises projection portions formed between the adjacent plurality of recessed portions, and the surface has a mold-proof effect.

(ZH)
散热片(50)具有金属基材(18Xr)和形成在金属基材上的多孔阳极氧化层(14),多孔阳极氧化层的表面具有亚微米量级的凹凸结构,凹凸结构包括从表面的法线方向观看时的二维大小为大于100nm且小于500nm的多个凹部(14Ap)、(14Bp),上述凹凸结构具有形成于相邻的上述多个凹部之间的突起部,上述表面具有防霉菌作用。
