Abstract

Abstract

In order to find a heat fin which matches well to the waist tube, the four main structural parameters including fin spacing(F_p), louver spacing(L_p), louver width(L_w) and louver angle(L_a), are optimized by using the orthogonal test and simulation. Then the influence of the each structural parameter on the heat transfer and pressure drop performance of radiator is obtained. It is found that the louver angle has the greatest influence on the performance of radiator, while the louver spaceing has the smallest influence. Based on the above results, the improved design structure is put forward. Finally, the wind tunnel experiments are carried out to compare the wasp waist tube radiator with the optimized radiator. The results show that the optimal louvered fin structure can obviously improve the air-side heat transfer and reduce the pressure drop.
