Enhancement of Natural Convection Heat Transfer From a Fin by Triangular Perforations of Bases Parallel and Toward Its Tip

  • 摘要: 研究一种设置水平矩形翅片对自然对流传热的强化作用,翅片内含三角形穿孔,三角形的底边平行并朝向翅片顶端.比较了这种多孔翅片和同等实心翅片的热耗散率.考虑的参数包括翅片及其穿孔的几何尺寸和热性能.讨论了翅片穿孔后引起的传热强化和翅片重量的减轻.结果表明,在某些三角形穿孔和穿孔间距的值域内,穿孔翅片改进了同等情况实心翅片的热耗散.当翅片导热率及其厚度增大时,穿孔翅片的传热也强化.
