Abstract
A method for manufacturing a heat exchanger is provided. The heat exchanger includes a plurality of plate-like fins that are stacked with a predetermined fin pitch, and a plurality of flat heat exchanger tubes that are disposed with a predetermined spacing from one another along the longitudinal direction of the plate-like fins and extend through the plate-like fins along the stacking direction. The plate-like fins each have a plurality of notches provided in an end portion along the long side. The plate-like fins have a shape corresponding to the cross-sectional shape of the flat heat exchanger tubes, and the flat heat exchanger tubes are inserted into the notches. The manufacturing method includes disposing the flat heat exchanger tubes with a predetermined spacing from one another, and attaching the plate-like fins to the flat heat exchanger tubes one by one by inserting the flat heat exchanger tubes into the notches of each of the plate-like fins.
