- Abstract
- In this study, a radial heat sink with a concentric cylinder and triangular fins installed on a circular base, that is, a heat sink representing a general shape of the heat sinks employed for most of the commercial LED light bulbs, was optimized in terms of mass and thermal resistance. A numerical study was performed by considering natural convection and radiation heat transfer, and was validated through experiment. The effects of various geometric parameters, that is, radius of heat sink base, number of fins, fin height, and radius of hollow cylinder, on thermal resistance and convectional heat transfer coefficient were investigated. Multiobjective optimization was conducted by using the weighted sum method and the genetic algorithm. As a result, Pareto fronts were obtained, and the thermal resistance and mass of the radial heat sink with triangular fins were reduced compared to those of the reference radial heat sink.
