ABSTRACT:
A method for assembling heat exchanger plate pairs by snap fitting with counter-rotating rotors move heat exchanger plates two at a time through paths which converge in a vertical mating plane. Arcuate guides engage the plate ends to control the plate path. The rotors are servomotor controlled to synchronously index the rotor in increments separated by dwell periods. After assembly the merged pairs drop between spaced guides into an assembly fixture. At a subsequent brazing operation each plate pair becomes a tube for carrying refrigerant.
