Abstract
This paper describes the effect of the shape parameters on the flow resistance of a perforated plate used as a vent plate or cover for electronic equipment. In this study, we focused on the effect of hole shape and presence or absence of holes near the outer edge as the shape parameters of a perforated plate. The study is about electronic equipment designed to be air-cooled by natural convection. To demonstrate the effect of hole shape as a usable parameter for design engineers, the design of experiment (DoE) method was used to design the experimental samples of perforated plate. The effect of the outer edge was evaluated by comparing the flow resistance of perforated plates with and without holes on the outer edge. In addition, the flow resistance data obtained in this study was arranged as an empirical formula.
