ABSTRACT:
A novel heat exchanger structure, for a hand-held adhesive gun of the type adapted to discharge a heated thermoplastic adhesive through a discharge valve located in the gun's barrel. In preferred form, the novel heat exchanger includes a heat exchanger core fixed in location within a heater body's bore. The heat exchanger core has spiral threads on the outer surface thereof, and the bore's surface has spiral threads thereon, too. The heat exchanger core's threads are sized relative to the inlet bore's threads such that the core can be threaded into the bore, and such that the threads cooperate to define a spiral path about the core through the bore from one end to the other, thereby defining a spiral heat exchange path through the gun's heater body. This novel heat exchanger is particularly adapted to elevate the temperature of the molten adhesive, just prior to dispensing it, above that temperature level at which the molten adhesive is supplied to the hand gun.
