Constructal Nano-Scale Heat Trees Used for Electronics Cooling

摘要：

In the present study, the optimal distribution of a highly-conductive material in heat-generating body of low-conductivity material is obtained. Using the constructal theory, the objective is to minimize the global thermal resistance between the entire body and a point heat sink by insertion of tree-shaped conduction paths of highly-conductive material into the heat generating body. Also in some cases, dimensions are below a certain length and therefore, conventional relationships for conduction are not valid. Thus, we use a more accurate model compared with other models used to predict the thermal conductivity. Finally, the optimal geometry is extracted and it is concluded that the complex embedded paths do not necessarily improve the performance.
