1. The ornamental design for a “heat exchanger fin,” as shown and described.

Description:

FIG. 1 is a front perspective view of the heat exchanger fin shown as a section because the pattern repeats;

FIG. 2 is a left end view of the heat exchanger fin of FIG. 1;

FIG. 3 is a right end view of the heat exchanger fin of FIG. 1;

FIG. 4 is a front side view of the heat exchanger fin of FIG. 1;

FIG. 5 is a backside view of the heat exchanger fin of FIG. 1;

FIG. 6 is a top view of the heat exchanger fin of FIG. 1; and,

FIG. 7 is a bottom view of the heat exchanger fin of FIG. 1.

The broken lines depict boundaries of the heat exchanger fin and form no part of the claim.
