摘要

Aiming at improving the air-side thermal-hydraulic performance of the assembled compact fin-and-tube radiator, an innovative wasp waist tube is proposed which is deformed from the traditional flat tube. The thermal-hydraulic performance of the wasp waist tube with different aspect ratios was compared with the flat tube using numerical analysis. The results showed that the heat transfer capacity of the wasp waist tube was better than that of the flat tube. The wasp waist tube with an aspect ratio of L/W = 5 was then selected with consideration of heat transfer capacity and manufacturing factors. Furthermore, the geometrical parameters of the louvered fin associated with the wasp waist tube were also optimized using the orthogonal experiment method. Various simulations were carried out using different models of varying air velocities and optimal parameters, namely, Fp = 2.52 mm, Lp = 1.5 mm, Lw = 3.58 mm, La = 23 degrees, were found among the cases studied. Finally, wind tunnel experiments were also carried out to compare the wasp waist tube radiator with the circular, oval, and flat tube radiators. The results showed that the proposed wasp waist tube and louvered fin structure could improve the air-side heat transfer of the compact radiator, which can be applied not only in the automobile industry but also in other potential applications.
