A method of assembling a plate fin coil by making sheets of single pass single row plate fins from plate fin stock. The fins within each sheet are connected by tabular portions and have openings for the receipt of hairpin tubes which form part of the flow circuitry of the heat exchanger. A plurality of sheets are arranged in registration so that hairpin tubes may be inserted through the openings within the fins to form partially assembled heat exchanger coil cores. The adjacent coil cores may be separated at this point by rupturing the tabular portions connecting the fins within the various sheets or additional process steps may be completed simultaneously upon the entire coil bundle having many coil cores. At some time in the plate fin coil assembly process the rows of plate fins are separated into single or multi-row coils by rupturing the tabular portions to form the appropriate row size coil core. A coil bundle formed by partially assembling coil cores having sheets of connected fins is also disclosed. |
