Through the appropriate assumptions, The mathematical model was derived in circumferential fin of rectangular profile , and then its modified conduction solution was amended, and the corresponding heat flow calculation formula was given. With the original formula, this solution enhance the accuracy and simple form of expression, can be easily used in engineering practice. Frosting fin on the design of a theoretical guide. and it can be extended to other heat transfer problems of fin.
