1. A heat dissipation fin, comprising at least two corrugated sheets arranged in a first direction, wherein two adjacent corrugated sheets are arranged opposite to each other, each of the at least two corrugated sheets has a length extending in a second direction, a first corrugated portion with a central line extending in a third direction is formed on each of the at least two corrugated sheets, a cross section of the first corrugated portion has a peak and a trough; and the first direction is perpendicular to the second direction,
wherein the heat dissipation fin satisfies the following relational expressions:
20°≤α≤40°;
A<−0.0138λ4+0.1911λ3−0.9145λ2+1.8944λ−0.5195; and
A>0.0064λ4−0.1003λ3+0.589λ2−1.4138λ+1.6181, where
α is an angle between the central line and the second direction;
A is a wave amplitude, i.e., a distance between the peak and the trough in the first direction; and
λ is a wavelength, i.e., a distance between two adjacent peaks in a fourth direction, wherein the fourth direction is perpendicular to the first direction and the third direction.
