Flow boiling of water in a circular staggered micro-pin fin heat sink
Flow boiling of water across a bank of circular staggered micro-pin fins, 250 lm long and 100 lm diameter with pitch-to-diameter ratio of 1.5, was experimentally studied for mass fluxes ranging from 346 kg/m s to 794 kg/m s and surface heat fluxes ranging from 20 W/cm to 350 W/cm. Local temperature measurements were used to elucidate the two-phase heat transfer coefficients. The flow was visual...
متن کاملResearch on Properties of Fluid Pressure Drop for Electric Vehicle IGBT Pin Fin Heat Sink
The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the fluid pressure and other parameters. In order to improve the cooling effect of Pin fin heat sink, diameter, length and distance of the fin was optimized combination. The relationship between pressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. It wa...
متن کاملThermal Performance of an Elliptical Pin Fin Heat Sink
Christopher L. Chapman, and Seri Lee Aavid Engineering, Inc. Laconia, New Hampshire 03247 Bill L. Schmidt Silicon Graphics Computer Systems Mountainview, California 94039 Comparative thermal tests have been carried out using aluminum heat sinks made with extruded fin, cross-cut rectangular pins, and elliptical shaped pins in low air flow environments. The elliptical pin heat sink was designed t...
متن کاملNumerical Optimization of Pin-Fin Heat Sink with Forced Cooling
This study presents the numerical simulation of optimum pin-fin heat sink with air impinging cooling by using Taguchi method. 9 L ( 4 3 ) orthogonal array is selected as a plan for the four design-parameters with three levels. The governing equations are discretized by using the control-volume-based-finite-difference method with a power-law scheme on the non-uniform staggered grid. We solved th...
متن کاملExtended Correlations for Staggered Round Tube Plain Fin Heat Exchangers
This paper develops a semi-empirical expression for heat transfer in round tube plain fin heat exchangers that have relatively large fin pitch. Empirical heat transfer correlations currently available in the public domain are necessarily limited in their range of applicability, and their functional forms are generally not designed to converge to well-known physical results, for example when par...
