ABSTRACT:
A method for making a heat exchanger assembly (10) includes the steps of simultaneously extruding hollow tubes (12) and bridges (14) integrally connecting adjacent tubes (12) through a die; and cutting holes (16) into the bridges (14) to allow airflow through the holes (16). The holes (16) are cut into the bridges (14) by cutting tongues (18, 118) into the bridges (14) and bending the tongues (18, 118) transversely to the tubes (12). Fin modules (20) are then inserted into each hole between the hollow tubes (12) to provide alternative heat exchange characteristics to those of the tongues (20) acting as the fins.
