Abstract: | A comparison between the heat loss of the asymmetric triangular fin and the asymmetric trapezoidal fins which have various
slopes of the fin’s upper lateral side is performed. The relation between the slope factor of the fin and the non-dimensional
fin length for equal amount of heat loss is shown. Further, the relation between the Biot number and the non-dimensional fin
length for equal amount of heat loss is given. For these analyses, a forced analytic method is used. In particular, the same
equation is used for both the asymmetric triangular fin and the asymmetric trapezoidal fins just by adjusting the value of
the slope factor. It is shown that this equation can also be applied to a rectangular fin with very good accuracy. The base
temperature, thermal conductivity of fin’s material and the heat transfer coefficient are assumed constant. |
