摘要

Due to the high efficiency in water transportation, the plant branching networks were widely investigated and used in designing the microchannel of mass flow and heat dissipation for electronic components. However, in current studies of fractal tree-like networks used in microchannel design, the wall was always regarded as a non-porous structure, and the porous tissue surrounding the network was overlooked, which is actually contrary to the real plant branching system, where water can penetrate into the surrounding tissue through the permeable wall. In this paper, the branching network with permeable wall and the porous media are designed to form a conceptual structure based on the real architecture of plant leaf. The effect of the permeable wall and the porous media on the performance of heat dissipation and flow is analyzed. The results show that, the permeable wall and the porous media play a very important role in heat spreader design.
