The interruption of a fin surface causes renewed boundary layers starting from the leading edge of each interrupted fin. This results in boundary layer thinner in the average over entire length of fin surfaces compared to the uninterrupted case. Therefore, a higher degree of interruption is normally expected to lead to a higher degree of heat transfer. However, to realize this expectation actually, care must be taken of the geometrical allocation of each fin in an array so as to avoid other undesirable effects relating to the fin geometry. Numerical computation of flow and thermal fields have been made for two-dimensional models of two types of parallel louver fins and an offset fin. Heat transfer characteristics of parallel louver fins are discussed in comparison with those of an offset fin based upon the results obtained from the performed numerical computation. It is demonstrated that a cartain type of parallel louver fin has a higher heat transfer performance than that obtained with an offset fin.
