Abstract
Apparatus for 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 process snorkel member comprising a bored plug for telescoping inside an extension tube extending from an open end of a heat exchange tube forming an end of a circuit in the coil, and a venting tube defining an air conduit from the plug to the atmosphere, whereby the pressure in the interior of the plate fin coil assembly is relieved when the fin coil is immersed in the solder bath.
