摘要： A condenser having two piece die formed condenser tube parts that are joined along a beveled outer edge. The tube material is braze cladded on both sides for corrosion resistance and for high quality internal braze bonding of (1) longitudinal tube webs for optimizing burst strength, and (2) the tubes to associated air centers which are not cladded for an economical unit. The tubes can be readily made in a multiport or single port design by die forming the longitudinal webs in each tube part, and at discreet lengths along the tube length to provide a cut off area for sizing the tube and a smooth circumferential area where the tube parts with a beveled outer edge enter the header providing a close fit and high quality brazed joints. This tube design provides material and cost advantages over the conventional extruded tubes or roll formed condenser tubes and is readily fabricated using corrosion resistant alloys providing long service life. The number and spacing of the webs in this construction can be readily made by changing the spacing of the dies for forming the tube parts. The method provided by this invention provides increased output with higher machine speeds as compared to extrusion type processes.

摘要： A convection braze furnace for brazing aluminum heat exchangers in an inert gas rich atmosphere includes entrance and exit vestibules forming atmosphere barriers of suspended stainless steel strips. The interior of the braze furnace is divided into multiple zones for progressively heating the heat exchangers to a brazing temperature and then cooling the heat exchangers in the final zone. An impeller circulates the heated inert gas atmosphere within each zone to accelerate heat transfer. A chain type conveyor supports the heat exchangers as they are moved through the braze furnace. An isolated return tube surrounds the lower return side of the conveyor chain as it passes through the braze furnace. The braze furnace housing is comprised of inner and outer shells having an inert gas pressurized cavity interstitial therebetween. The inner shell includes a plurality of expansion strips having generally ellipsoidal corner expansion joints.

摘要： A high capacity condenser for automotive application is built up from two layers or modules so as to make maximum use of standard components. The tanks of header tank and tube type condensers are extruded with interfitting clearance notches and stand-off flanges along the length of the tanks that maintain the two modules spaced apart and aligned. A specially designed cross-over pipe interconnects the two modules in a fluid sense and also cooperates in mechanically joining the two.

摘要： 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.

摘要： An improved method for assembling a brazed heat exchanger unit suitable for use in an automobile air conditioning system. Prior to assembly, a sufficiently viscous flux-brazing composition is selectively applied to the internal and external features of the heat exchanger which serve as the joining surfaces of the heat exchanger. The flux-brazing composition is specifically applied to the internal surfaces of the aluminum alloy header and the external surfaces of the tubes so as to form uniformly and consistently brazed internal and external joints. The flux-brazing composition of this invention consists of potassium tetrafluoroaluminate particles, an aluminum-silicon powder, zinc and a binder. The flux-brazing composition enables the selective application of both a flux compound and a brazing compound, eliminating excessive use of flux and eliminating the need to clad the components of the heat exchanger with an aluminum alloy brazing material.
