Claim:
A universal fin for use in a fin on tube heat exchanger, the universal fin comprising: a sheet of heat conducting material configured to be separated to form one or more continuous fins for use on the fin on tube heat exchanger regardless of a number of vertical and horizontal pairs of tubing segments in said heat exchanger, said sheet having a width and a height; and a plurality of openings in said sheet, each of said openings configured to allow a pair of generally parallel tubing segments of the heat exchanger to pass therethrough, each of said openings being canted relative to said width and height of said sheet, each of said openings being arranged on said sheet into a plurality of rows and into a plurality of columns with adjacent rows being generally equally spaced apart and with adjacent columns being generally equally spaced apart, and said spacing between adjacent rows and between adjacent columns being dimensioned to allow said sheet to be separated between at least one of said adjacent rows and said adjacent columns to form one or more continuous fins each containing a plurality of openings at least equal to a total number of pairs of tubing segments in the heat exchanger.
