W121004 Multi-objective Optimization Technique in Thermal Design Inspires Japanese MONOZUKURI

Abstract

We present the multi-objective optimization method for thermal design. A pinfin heatsink is considered as an example of thermal design. Thermal resistance and pressure drop were the objective functions, and four geometric parameters, height, diameter, longitudinal pitch, and transverse pitch, were the design variables. The relationship between the objective functions and the design variables for pinfin heatsink was calculated. We claim and prove that this method is applicable to obtain design rules.
