The arrangement configuration of delta wing and elliptical cylinder were cautiously carried out on spiral warped channel wall layers of combination vortex generator. Based on numerical simulation FLUENT to study the influence of three parameters on heat transfer

including assembly distance s

triangle wing angle of attack α and elliptical cylinder angle of attack β which were discussed within the Reynolds number Re range from 4000 to 7000. Then using Orthogonal experiment methods to optimize the vortex generator structure entirely

obtaining the order of priority and optimum composition structure on heat transfer. Comparing with experimental test

the intensified heat transfer effect was reinforced by optimizing structure and normal structure of composite. The results show that α=45°

β=45°

s=90mm can have the comprehensive effect on heat exchanger optimum. what’s more

the intensified heat transfer is higher 18.9%~38.3% than ordinary .Therefore

the accuracy and validity had been confirmed definitely.
