摘要： A method and apparatus for automatically assembling hairpin tubes in the tube receiving holes of a fin pack unit. Pre-assembled fin pack units are serially moved from one station to the next to receive hairpin tubes, to have bells formed in the open ends of the laced hairpin tubes, to have expansion tools inserted upwardly through the open ends of the hairpin tubes to expand the walls of the tubes outwardly into contact against the fin plates and tube sheets with sufficient force to lock the tubes into the unit, and to have return bends interconnect the bell-like seats of adjacent hairpin tubes and thus complete the heat exchanger flow circuit.

摘要： Apparatus for automatically loading a series of hairpin tubes into a magazine that is used to temporarily store the tubes so that they can be later laced into a fin pack. The magazine contains individual open-ended compartments for receiving and storing the tubes therein. The compartments are indexed into a loading station having a ram for driving hairpins into the indexed compartment. A gripping mechanism is also located in the loading station having fingers that engage the extended legs of the hairpin and guide the legs into the magazine compartment.

摘要： A method of manufacturing a heat exchanger using fluidic expansion, the heat exchanger having tubing sections interconnected to form at least one circuit for transporting a first heat transfer fluid and conductive fins secured to the circuit for increasing the surface area thereof and increasing the heat transfer between the first fluid and a second fluid flowing among the fins. The tubing sections are positioned in a predetermined manner and the fins are disposed therewith and along the length thereof. The inlets and outlets of the tubing sections are then interconnected to form said the fluid circuit. Next, the fins are secured in place so as not become damaged during the sealing of the interconnections, which follows immediately thereafter. Finally, the entire circuit is expanded to enmesh said fins by enclosing the volume of the circuit and introducing an expansion fluid therein at a pressure which surpasses the tube yield strength of the tubing and causes the walls thereof to expand radially outward.

摘要： An apparatus for expanding the tubes in a heat exchanger of the plate fin and tube type. The expander is of the type that expands the tubes by driving an expansion "bullet," attached to and driven by an expander or bullet rod, through the tube. The expander rod in turn is driven by a ram. The expander has a rod support apparatus that prevents the expander rod from buckling under compressive stress. The axes of movement of the ram and the expander rod are offset with the ram imparting its force to the rod through a connector link. A rod support member has a passage to support the expander rod, a passage to allow the ram to pass through the support member and a slotted passage, to allow the connector link to pass through the support member, joining the rod support passage and the ram passage. The rod support apparatus restrains the expander rod from buckling while requiring no increase in the overall length of the tube expander.
