本研究发展一实用的模型来预测板翅式散热器的水力与热力性能。该一体化渐近模型适用于各种雷诺数，包括Re<5000时的层流、转捩和湍流。它可以预测压降，精度在-13.87%至8.4%之间。当雷诺数在2000 ~ 4000之间时，该渐近模型解释了过渡流的传热行为，误差范围在-14%至12%以内。此外，本研究实现了几何优化与本模型。当压降固定在10 mmAq，翅片高度固定在24 mm时，提供了翅片间距、基部厚度、基部宽度、基部长度和翅片厚度的最佳值。
This study develops a practical model to predict the hydraulic and thermal performance of a plate-fin heat sink. This all-in-one asymptotic model was developed for a wide range of Reynolds numbers, including laminar, transition, and turbulent flows as Re<5000. It can predict pressure drops with an accuracy within −13.87% to 8.4%. This asymptotic model interprets the heat-transfer behavior of transition flow to within −14% to 12% of error range when Reynolds number ranges from 2000 to 4000. Furthermore, this study achieves optimization in geometry with the present model. While the pressure drop is fixed at 10 mmAq, and the fin height is fixed at 24 mm, optimal values for fin spacing, base thickness, base width, base length, and fin thickness are provided.
