ABSTRACT:
Apparatus and method of venting a plate fin coil during the ultrasonic soldering of aluminum return bend tubes to the heat exchange tubes in the coil. The apparatus includes a snorkel member arranged on the heat exchanger carrying mechanism whereby one end of the snorkel is telescoped in the open end of a heat exchange tube forming an end of a circuit in the coil, with the other end communicating with the atmosphere, whereby pressure in the interior of the circuit is relieved when the coil is immersed in the solder bath.
