Abstract:

The microstructures of several typical leaves were measured and analyzed to get the diameter, angle and diameter ratio for each levels of leaf vein. The CAD model and simulation of heat and flow in a two-layer dendritic microchannel network for chips cooling were conducted. The simulation results show that the temperature distribution is more uniform in the tree-like microchannel than that in the paralell microchannel. The temperature and pressure drop are lower in the tree-like microchannel with 7 level branches than that with 6 and 8 level branches.

Key words: microchannel, pressure drop, heat transfer, flow
