Effect of Header Design on Pressure Drop in Microchannel Heat Sink for MEMS Applications

Abstract:

Experiments have been performed to investigate the pressure drop in the microchannel heat sink by varying the cross sectional shape of the header at the inlet and at the outlet for two types of arrangement U type and Z type. The experiments are performed by using deionized water as a coolant for a mass flow rate of 50 – 120 kg/hr and Reynolds number of range 100 - 600 in an Al microchannel rectangular heat sink with 25 numbers of parallel microchannels. Experiment was carried out to find the suitable inlet and outlet header combination for both U type heat sink and Z type heat sink. The various cross sectional shapes used in this micro channel are triangular, trapezoidal and rectangular.
