Thermal 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...

A Cfd Analysis of the Performance of Pin-fin Laminar Flow Micro/meso Scale Heat Exchangers

Numerical 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...

Optimal Shape Design for a Cooling Pin Fin Connection Profil

A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined as maximizing the norm of the Nusselt number distribution at the boundary of the pin fin's con...

Investigation of Pin Fin Cooling Channels for Applications in Gas Turbines

Researcher: Royce Fernandes Title: Investigation of Pin Fin Cooling Channels for Applications in Gas Turbines Institution: Embry-Riddle Aeronautical University Degree: Master of Science in Aerospace Engineering Year: 2016 Gas turbine blades are often cooled using internal cooling channels to prevent failure at temperatures beyond material limitations. Pin fin channels are commonly used on the t...
