Abstract
This paper suggests a new engineering design methodology by utilizing the optimality of branch systems in nature, such as botanical tree and root systems, animal vascular systems, and so on. The growth mechanism of branch systems in nature is studied and the growth process is reproduced. By applying the generation method of the branch system, a branch-like cooling pipe is generated inside a thin plate applied with a heat flux on its surface. Because such branch-like cooling pipe system has the similar optimality with the branch systems in nature, better cooling performance of the cooling structure is expected. Finite element analysis of temperature distribution is implemented to confirm the validity of the generation method.
