摘要

A new pattern of wick in vapor chamber is designed and analyzed in this study. The wick is a kind of leaf-vein-like fractal architecture with polygon loops which are composed of many Y-shaped bifurcations, for this reason that the condensable area is enlarged efficiently. The polygonal loops play a unique role in avoiding blocking. And the sucking capacity is introduced to evaluate the wick performance. The permeability in both the length and height direction as well as the resistance in length direction are calculated, and compared with the parallel structure. It shows the permeability in both directions is far greater than that of the parallel structure under the same power source condition. Not only that, the resistance is far less than that of the parallel structure as the reasonable width ratio was chose. The analytical results indicate that the leaf-vein-like fractal architecture has better performance than the parallel structure.
