A total of 51 patents were examined and compared. Fin patterns like convex-louver, enhanced wavy, enhanced slit, enhanced louver, vortex generators, and several special fin patterns are reported in the present report. It is recommended that further detailed examinations via numerical simulation or experimental investigation be carried out in the future to gain further insight of these fin designs. %8 2018-04-23
