Abstract

Abstract

Heat transfer enhancement from a horizontal recrtarrgular fin embedded with triangular perforations (their bases are parallel and toward to the fin tip) under natural convection is studied.Its heat dissipation rate was compared to that of the equivalent solid one.The parameters considered were geometrical dimensions and thermal properties of the fin and of the perforations.The gain in heat transfer enhancement and the fin weight reduction due to the perforations was considered.It is shown also that the heat dissipation from the perforated fin for certain range of triangular perforation dimension and spaces between perforations result in improvement in heat transfer over the equivalent solid fin.The heat transfer enhancement of the perforated fin increases as the fin thermal conductivity and its thicluress are increased.
