The goal of this thesis is try to assist engineer to design an effective Heat Sink, which intent to have the most effectiveness in handling maximum heat dissipation is presented , under limited space. And, the material cost and weight are also under consideration in this study.
The purpose of this study is focusing on the Longitudinal Rectangular Heat Sink, which the volume and fin number as well as one side depth have already known, for the length, width, and cross section area. Using the equation of maximum heat dissipating, accumulates the radiator fin on the fin area, add up the surface heat of a single fin and the bottom heat between fins for the total heat dissipating capacity of the Heat Sink. Through the dimensionless parameter input, formula simplification, then the method for the optimized value. Then use the Optimum for the maximum efficiency, the length of the other side, the height and thickness of thin, and the thermal resistance value. And clarify the radiation benefit.
In the process of computation, we have to consider Fin Tip Convection of the fin peak and fin peak thickness in this research. The whole result of the computation demonstrated that the fin peak heat convection and fin peak thickness do not have any influence to the entire radiation efficiency. So, it may be ignored during the computation. According to the computed result, the maximum heat dissipating capacity appear in, compares approximately, between 0.27~0.33 in the fin volume density. This data may work as the reference for the fin piece number in designing the radiator.
