Heat exchanger fin

Description

FIG. 1 is a front, perspective view of a heat exchanger fin embodying the principles of my new design;

FIG. 2 is a front view thereof;

FIG. 3 is a rear view thereof;

FIG. 4 is a side view thereof as seen from the right-hand side of FIG. 2;

FIG. 5 is a side view thereof as seen from the left-hand side of FIG. 2;

FIG. 6 is a top view thereof;

FIG. 7 is a bottom view thereof; and,

FIG. 8 is a cross-sectional view taken along line 8--8 of FIG. 1.

The broken lines illustrate portions of the heat exchanger fin and form no part of the claimed design. The heat exchanger fin is shown with a symbolic break in its length and its width. The appearance of any portion of the article between the break lines forms no part of the claimed design.

Claims

CLAIM The ornamental design for a heat exchanger fin, as shown and described.
