Experimental study on the performance of a novel fin-tube air heat exchanger with punched longitudinal vortex generator

► Two novel fin-tube heat exchangers with delta winglet pairs are experimentally studied. ► Heat transfer enhancement accompanying with a reduction of pressure loss is achieved. ► Optimization of the location, orientation and size of delta winglet should be done for practical use. To enhance the hea...
