Abstract

The Aihara correlation is used to determine the optimal spacing and diameter for an isothermal array of fixed volume, appropriate for use with electronic equipment. A least-material optimization of these arrays is performed by extending the use of least-material single pin-fins to multiple pin-fin arrays. This analysis provides an engineering upper bound for heat dissipation from a fixed base area. The influence of the length of the pin-fin on the optimal horizontal spacing and diameter, and the optimal heat dissipation, from a fixed base area, are discussed, with reference to a specified heat sink configuration.
