An experimental study of natural convection heat transfer within a rectangular enclosure from the heated triangular fin array has been performed. The present study reported that increasing Ra (365214 ≤ Ra ≤ 683826) and fin height the Nu increases continuously. While Nu increases initially up to an extreme value, then tends to decrease by decreasing in fin spacing. The fin effectiveness increases with increase in fin height and it increases initially up to a maximum value, then tends to decrease with a decrease in fin spacing. The correlations are developed for Nu and verified with experimental data.
