碩士 / 國立高雄應用科技大學 / 機械工程系 / 105 / The thesis of optimization theory and field synergy principle is applied to to explore the relationship between the performance of heat transfer and field synergy angle with the heat fins under forced convection (fan cooling).
First, the thermal transfer enhancement of fins at different fin height, fin angle and fin circumference of three design parameters utilizing multi-objective response surface methodology to identify the most suitable simulation equations.
The goal of the response value is to make the overall average field co-angle and the fin average temperature is small. The Taguchi method was used to verify the contribution of the factor level, the noise ratio and the variance of the factors displayed at the synergistic angle and the average temperature of the fins. The optimal solution of the response surface methodology and the Taguchi method is simulated by two kinds of experimental design methods. The optimal temperature of the fins under different optimization methods is obtained. The global average field synergy angle difference, to explore the model of heat transfer efficiency and physical properties.
The results show that the average temperature of the fins is 2.28% and the overall average field synergy angle is improved by 3.15%. In the field of Taguchi, the average temperature of the fins is improved for the fin temperature target Fin average temperature: 7.26%; overall average field synergic angle: 1.75%; for the overall average field synergistic angle to improve the fin average temperature: -0.16%; the overall average field synergy angle: 4.47%, so take the most Good combination of fin height: 50mm; fin angle: 60∘; fins aliquot: 4. (5.25%)> fin angle (1.58%), the contribution rate of the factor is less than the average of the fineness of the fins, and the contribution rate of the fins is 93.17% : Fin angle (79.92%)> fins equal (16.13%)> fin height (3.95%).
