An experimental study to enhance heat transfer by generating a longitudinal vortex with a rectangular winglet has been investigated. Two angles presented (70°, 35° ) in rectangular winglet placed at the entrance of heated channel the study shows the pointing (Down and Upstream) and the effect of attack angle depends on the heat transfer (Nu)and the friction factor (f ) for each angle and two sides, the Reynolds number range from 5000 – 23000. It was found that angle was a significant effect on the heat transfer coefficient and the 70° angle is more efficient in heat transfer at high velocity and the pointing downstream make a good result in heat transfer.
