A concave parabolic fin with vertically cut fin tip is analyzed using a two-dimensional analytical method. Heat loss and fin efficiency are presented as a function of the actual fin length, the ratio of actual fin length to imaginary fin length, the fin base height, and the convection characteristic number. For equal amounts of heat loss, the relationship between the convection characteristic number and the fin base height as well as that between the actual fin length and the fin base height is presented. One of the results shows that heat loss decreases at first and then increases as the ratio of actual fin length to imaginary fin length increases.
