Rapid Heterogeneous Transport Using Micro/Nano Hierarchical Dendritic Mesh Wick

This paper reports a multi-scale micro/nano hierarchical dendritic mesh wick (HDMW). This structure controls the gradient deposition of dendrites through the generation and migration of hydrogen bubbles, thereby achieving and enhancing heterogeneous transport capabilities. The research results show that the capillary comprehensive evaluation parameter ∆P ∙ K of HDMW is as high as 2.71×10⁻⁷ N. At a working temperature of 80°C, the maximum heat transfer limit of HDMW-Opti reaches 73.51W, which is approximately 70% higher than that of Plate-Opti. Its highly dense and complex multi-level branching structure not only increases the specific surface area but also forms effective fluid channels, thereby enhancing the heterogeneity of capillary forces and liquid flow.
