Application of splitter plate on the modification of hydro-thermal behavior of PPFHS
چکیده انگلیسی
This paper presents a Splitter Plate Pin-Fin Heat Sink (SPPFHS) as a new kind of heat sink to enhance hydro-thermal performance of heat sinks. To reach this purpose, a thin plate known as a splitter is located behind the pin-fin. According to the numerical results, placing the splitter behind the pin-fin, reduces the thermal resistance and pressure drop on the heat sink. Splitter streamlines the flow around the cylinder and decreases the pressure drop around the pin-fins. Besides the pressure drop, increase of heat-transfer area dominates the heat transfer coefficient reduction and results to thermal resistance decrement. Furthermore, for considering the both thermal resistance and pressure drop effects; non-dimensional parameter of profit factor (J) is computed. Comparison between present SPPFHS and Plate Pin Fin Heat Sink (PPFHS) confirms the ability of splitter in modification of hydro-thermal behavior of heat sinks by simultaneous reducing the pressure drop and thermal resistance.
