<p>P R O C E S S F O R F A B R I C A T I N G A H E A T E X C H A N G E R An ultrasonic dip soldering process for bonding the tubular joints of a heat exchanger made up of tubular components joined together to form flow circuits within a fan coil. The joints are positioned adjacent to one of the tube sheets of the fan co 1 structure and the joints preheated by means of a remote heating process. The joints are then immersed in a molten bath of solder and treated to ultrasonic energy while in the bath.</p> |
