ABSTRACT:
A method of making an automotive heat exchanger comprises the steps of assembling a heat exchanger core having a plurality of interleaved tube and fins disposed between a pair of endsheets and expanding the diameter of the tubes a predetermined distance by forcing an expansion tool therethrough. The tubes of the heat exchanger include a plurality of internal projections of predetermined height and the expansion process decreases the height of the projections by less than 25% of its original height. A heat exchanger formed in accordance with this method is also disclosed.
