Computational Analysis on Performance of Heat Sink with Different Configurations of Fins Array


  • Mechanical Department, Chandigarh University, Gharuan, Mohali - 140413, Punjab, India


Objectives: The aim of present work is to find out the thermal performance of solid and perforated heat sink with various perforated designs (Rectangular, Circular and Slotted). Methods/Statistical Analysis: The CFD analysis was performed to investigate the thermal performance of different perforation design. The test has been conducted in a horizontal rectangular duct equipped with forced draft fan. The data was obtained by varying flow velocities of air from 2, 5 and 8m/sec and maintaining constant heat input 100 Watt taken over a period of time. Findings: In this computational analysis we calculate the Heat transfer coefficient, Reynolds number and Nusselt number and obtain the result. The results show the heat transfer coefficient is more in circular perforated fin as well as more Nusselt number as compared to slotted and rectangular Perforation. Application/Improvements: Electrical component, higher-power lasers, refrigerator, air condition, Computers etc.
