The composite fins composed of a porous polyethylene core, a square aluminum insert, and metallic zinc coating layers, was fabricated using wire-arc spraying technology. Analytical solutions of temperature distribution, energy dissipation and fin efficiency through the fins at natural convection condition have been proposed.enThe copyright for the paper content remains with the author.Heat TransferComposite finsHeat conductionAnalytical modelArticle
