Abstract: In a method of manufacturing a condenser for a refrigerator, a heat discharging tube is attached to a heat discharging plate made of ABS resin to improve a heat discharging effect of the condenser, while a back portion of the refrigerator is covered with the heat discharging plate to improve an external appearance. A heat discharging tube is disposed on a lower molding jig, and the heat discharging tube is covered with a heat discharging plate. An upper molding jig and a lower molding jig are combined with each other, and air is discharged between the lower molding jig and the heat discharging plate to create vacuum therebetween so that the heat discharging plate is combined to the heat discharging tube by a vacuum-sucking force. The heat discharging plate is refrigerated in a state of combining the heat discharging plate to the heat discharging tube after separating said upper molding jig and said lower molding jig from each other, and then the heat discharging plate integrally combined to the heat discharging tube is separated from the lower molding jig.

Abstract: A plurality of heat transfer tubes are disposed at certain intervals, in-tube operating fluid (such as coolant) passes therethrough, and a plurality of small-gage wires are used as a heating fin. One small-gage wire is wound at a pair of heat transfer tubes 1a and 1c in a spiral manner, and another small-gage wire is wound at a pair of heat transfer tubes 1b and 1c in the spiral manner, and still another small-gage wire is wound at a pair of heat transfer tubes 1b and 1d in the spiral manner. Thereby, while higher heat transfer coefficient can be achieved, and a heating surface area is ensured, clogging can be avoided even when moisture in air condenses on a surface of a heat exchanger. As a result, it is possible to realize a high-performance and compact heat exchanger used for air conditioning.

Abstract: A motor-vehicle latent-heat storage unit is made by first positioning an elongated rectangular sheet-metal blank over a longitudinally extending slot formed in a die and then pressing an elongated anvil bar forming one of a pair of ultrasonic welding tools down against the blank over the slot to push the bar and the blank into the slot. This imparts to the blank a U-section and leaves longitudinally extending edge regions of the blank projecting out of the slot past the anvil bar. These edge regions are then folded transversely one after the other inward over the bar to form the blank into a tube with the edge regions overlapping each other. The other of the ultrasonic welding tools is subsequently pressed against the overlapped edge regions and therethrough against the anvil bar to ultrasonically weld together the overlapped edge regions along a full length of the tube. Finally the welded tube and the bar are moved longitudinally relative to each other to separate the tube from the bar.

Abstract: It is common practice to assemble heat exchangers from a multitude of pre-formed and sometimes extremely delicate pieces. The pieces have to be held in jigs along with appropriately placed braze material and then heated to achieve brazing. The invention takes advantage of the ability which some materials have to considerably extend their areas without rupturing by using such materials in that they are assembled in the flat condition and then diffusion bonded, followed by inflation of the parts of the assembly which are to provide the fluid passageways, inlet manifolds and headers. The construction of heat exchangers is thus considerably simplified.

Abstract: A muffle furnace assembly for brazing aluminum heat exchanger workparts comprises a tubular muffle having a workpart conveyer extending therethrough. A pair of fans disposed inside the muffle circulate high temperature atmosphere through the workparts. The muffle is surrounded by an insulative outer shell spaced to form an interstitial cavity therebetween. High temperature combustion gasses are directed into the interstitial cavity and flow in a helical path about the muffle. Louvers are provided in the muffle, between the workparts and the fans, for regulating the amount of inert gas flow within the muffle. Inlet and exit vestibules usher workparts into and out of the furnace assembly to minimize oxygen contamination within the muffle.

Abstract: A heat exchanger includes exchanger tubes which are narrow in flow direction of an outer exchanger medium. Always two adjacent exchanger tubes are connected to each other by fins which are either U-shaped individual or are components of a meander-like fin strip. The tube sides are connected to bases of the individual fins or to contact portions of the fin strips by welding, particularly by fusion welding on the inner surfaces of the tube sides. The exchanger tubes are formed by two tube shells which are welded together at the longitudinal edges thereof after two adjacent tube shells have been connected to each other by the fins. The ends of the tubes are placed in tube plates. The resulting heat exchanger is completely galvanized and does not require support structures.

Abstract: A method of brazing a temporarily assembled heat exchanger includes the steps of spraying an ionized fluid such as water on one surface. A powdered electrostatically charged flux is blown onto the opposite surface of the heat exchanger. A portion of the powdered flux is attracted to the one surface by the ionized fluid. Therefore, the flux material is uniformly spread across the heat exchanger. Finally, the heat exchanger is heated and brazed.

Abstract: The fillet-forming ability of brazeable aluminum alloy materials, such as brazing sheet or heat exchanger components, for example fins, tubes and headers, is significantly improved by treating the material, prior to brazing, with an aqueous acid solution containing a dilute mixture of HF and HNO.sub.3. The treatment generally takes place for a period of not less than 5 seconds within the temperature range from about 15 to about 98.degree. C.
