ABSTRACT:
A multi-row, finned tube heat exchange coil is made in a process particularly useful where the tubes and end fittings are both of aluminum, by arranging all of the hairpin-shaped tubes with their bights on the one end of the coil along with all of the complex connecting fittings such as tripods, inlet and outlet distributor headers and crossovers, and with the return bends all being arranged at the other end of the coil, and then soldering all of the return bends to the open ends of the tubes at that end of the coil.
