This study is about a numerical simulation of flow in three different models
microchannel heat sinks. Microchannel is a very important component to help in retain
electronic device temperature below the maximum allowable temperature which has
been specified by device manufacture. It is a basic hydraulic channel with size
1.00milimeter and 100.00micrometer. The ANSYS Fluent Software was used to predict
the flow in the three types of microchannel, the microchannel are labelled as
Microchannel A 0.50 mm x 0.50 mm, Microchannel B 0.50 mm x 0.75 mm and
Microchannel C 0.75 mm x 0.50 mm. The main objective of this study was to identify
the pressure drop and velocity across the three designed microchannel heat sink.
Besides, water is been used as the coolant in this study and aluminum is used as the
solid material of the design. The initial velocity was set in 0.1m/s and the highest
pressure drop was recorded for the Microchannel A which is square shape
microchannel.
