Enhancing heat transfer in a plate-fin heat sink using delta winglet vortex generators

In this study, both experiments and simulations are performed to investigate the thermal-fluid characteristics of a flat-fin heat sink with a pair of vortex generators installed in a cross flow channel. The effects of the distance between the trailing edges of the vortex generators, the distance between each vortex generator and the heat sink, the attack angle of the vortex generators, the height of the vortex generators, the configuration of the vortex generators, and the Reynolds number on the thermal-fluid performance of the plate-fin heat sink are elucidated. The performance of the heat sink with the vortex generators was compared to that without.
