Experimental Comparison of Thermal Resistance for Micro pin fin heat sinks with different shapes and arrangement
Resumo
In the present study, a comparative study of thermal resistance
of the micro pin fin heat sinks with different shapes (square
and elliptical), and arrangements (interrupted and staggered)
is presented. Experiments are performed on micro pin fin heat
sink using deionized (DI) water as the coolant. A numerical
model with suitable boundary conditions is developed and
validated with the experimental results by comparing pressure
drop and temperature at different locations of micro pin fin
heat sink. The conjugate heat transfer effect (in numerical and
experimental results) shows considerable temperature
variations in the inlet and outlet collectors of the micro pin fin heat sink. It is found that the shape of micro pin fin heat sink has considerable effect on the thermal resistance as compared to arrangement.
