A de-ionized water cooling system consisting of a microchannel heat sink and some equipment that can be applied to a chip is suggested. To optimize the structure, three kinds of pin fins (rhombus, pentagon and hexagon) are described. The heat transfer performance, the fluid flow and the pressure drop of the microchannel heat sink are simulated by commercial CFD solver Fluent. The inlet and the outlet...
A micropin array heatsink with high heat removal capacity for its optimised pin height and inlet–outlet positions is presented. Computational fluid dynamics simulation indicates pin height has a big impact on the pressure difference and heat removal capacity. A decrease of 2.67°C of the maximum temperature was achieved when pin height increased from 200 to 500 µm. Meanwhile with the proper pin height,...
