摘要：

Inspired by the fractal pattern of mammalian circulatory and respiratory systems. It new design of fractal branching channel net for cooling of electronic chips is studied in this paper. A comparison of file new design with the traditional parallel net shows that the new fractal branching channel net has a stronger heat transfer capability and requires a lower (C) 2002 Elsevier Science Ltd.
