ABSTRACT:
A method of assembling a plate-fin heat exchanger including the steps of providing a plurality of like substantially straight elongated plate-fins with spaced holes, bowing the plate-fins to increase their stability and accumulating a plurality of bowed plate-fins in stacked contiguous relationship to provide a bundle, providing a plurality of elongated substantially parallel tubes spaced from each other substantially the same distance as the spaced holes and oriented substantially perpendicularly to the bundle of plate-fins, transferring the bundle of bowed plate-fins to a carriage, straightening the bundle of contiguous plate-fins from the bowed condition to a straightened condition, and transferring the bundle of plate-fins in the stacked contiguous straightened condition onto the plurality of elongated substantially parallel tubes.
