A new enhancement technique was developed for natural convection heat transfer from a horizontal heated plate. In order to enhance the heat transfer, the grid fins made of copper plates were soldered to the base plate. These grid fins function not only as an extended surface but also as heat transfer promoters. The apparent heat-transfer coefficients of the above enhanced plate were measured and compared with those of a nontreated, flat plate and a conventional plate with vertical straight fins. It was found that the highest performance is achieved for the present plate. By adopting grid fins with appropriate size and height, the heat-transfer coefficient at the central portion of the present plate is increased by 35% compared to that of the conventional finned plate with the same fin area and fin height.
