Combined Experimental and Numerical Study of a New Configuration of Multiple Microchannel Heat Sink for Heat Removal
In this paper, single phase incompressible liquid flow in a new microchannel heat sink design, which includes flow bifurcation, is studied experimentally and numerically. The experimental setup and device fabrication are briefly explained. The experimental results are presented with uncertainty in the measurements. The numerical model is based on a commercial code and is validated by experimental results with the same initial and boundary conditions. Numerical results with both constant fluid properties and variable properties are compared with the experimental data. The thermal-hydraulic performance of the new design is investigated. The effects of the resulting fluid flow and the geometry on the thermal resistance of the system are discussed.
