Abstract

This project primarily focuses on the design and analysis of fins under uncertainty heat capacity. Three finned heat sinks with different geometry are selected at a fixed volume. The design parameters of fins are identified and considered with geometrical dimensions through reviewed literature. System constraints such as maximum operating temperature of central processing unit and air temperature surrounding the heat sink are also defined before simulation. Aluminium alloy 6063 which has considerably high thermal conductivity is used as the material of finned heat sink. CAD software which is SolidWorks 2010 is used to conduct 3D modeling of the fin designs. Finite element analysis is performed by using ANSYS software. At first, the 3D fin models which including heat sinks with plate fins, strip fins, and splayed are analyzed under steady state condition in order to investigate their temperature distribution and total heat flux. However, static structural analysis is performed also to obtain the factor of safety for each fin design. Weighted scoring model is generated by referring to the relevant criteria. In addition, the splayed finned heat sink is chosen as the best fin design and an improved design is proposed based on the findings from the steady state analysis. Transient thermal analysis of the selected finned heat sink and proposed finned heat sink with perforations is conducted respectively. As a result, the perforated finned heat sink is selected as the most superior design in sense of thermal performance.
