Abstract: Provided are a heat dissipation fin construction method, a related apparatus, and a heat dissipation fin. The heat dissipation fin construction method comprises: setting a plurality of structural parameter sets according to the preset numerical ranges of the twill angle, the wave amplitude, and the wavelength of a heat dissipation fin; separately obtaining respective heat transfer coefficients and air side pressure drops of the structural parameter sets, and establishing a fitting relationship between the heat transfer coefficients and the air side pressure drops for structural parameters; generating a corresponding performance map and a corresponding contour map on the basis of performance data of the fitted structural parameter sets; and determining an optimization interval of the wave amplitude and the wavelength of the heat dissipation fin according to the contour map, and constructing the heat dissipation fin according to the optimization interval.
