Thermohydraulic Effect of Nozzle Size and Introduction of Dimpled Surfaces in Heat Sink for Thermoelectric Refrigerator
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 4
Abstract
The computational study of water jet cooled hot side heat sink for thermoelectric refrigerator has been analyzed to study the effects of change in nozzle length (l) and diameter (d) on various parameters like the convective heat transfer coefficient, thermoelectric resistance, pressure drop and Nusselt number. It was observed from the analysis that nozzle configuration of l=3 mm and d=1 mm gave maximum value of the heat transfer coefficients as compared to other nozzle geometries considered at various flow rates. Computational studies have been done to analyzed the heat sink performance by introducing dimple surfaces of three different diameters of 1mm, 2mm and 3mm at the inlet port of 8 mm. Results were further more analyzed for nozzle configuration of l=3 mm, d=1mm with respect to the temperature differences of target surface and exiting fluid, for various flow rates from 1-5 litres per minute. Results showed that heat sink model with dimpled surfaces of diameter 3 mm gives maximum Nusselt number and convective heat transfer coefficient; high Pressure drop at lesser thermal resistance.
