Résumé

This article exposes the problem of determining the shape of a straight cooling fin of minimum volume without the "length of arc" assumption. Proceeding from the conventional assumptions of one-dimensionality of the temperature distribution and its linearity for the minimum volume fin, the authors found the profile of the optimum fin to be a circular arc and computed its geometric parameters. The volume of the optimum circular fin found in the paper is 6.21-8 times smaller than the volume of the corresponding Schmidt's parabolic optimum fin. The optimum circular fin tends to be shorter and to have a greater base height than Schmidt's fin.
