Abstract: A method and apparatus especially useful for supplying inert gas to a highly pressurized pressure vessel, such as a hybrid inflator for an automotive airbag module, and weld sealing the gas passage or opening therein to avoid or substantially eliminate weld cracks. The apparatus for accomplishing same comprises no moving parts and the welding is accomplished by utilizing either a groove or a conical rise feature formed into the end plug or wall surface of the pressure vessel wall surrounding the gas passage or opening so that no additional filler material is required to obtain the weld seal. The method and apparatus may also be used to weld seal low or non-pressurized vessels as well as vacuum vessels.

Abstract: A heat exchanger for an automobile air conditioning system and a method for manufacture of the same. The heat exchanger a plurality of refrigerant flowing tubes, a plurality of corrugated fins sandwiched between the tubes and a pair of header pipes liquid-tightly brazed and jointed to the opposite ends of the tubes respectively. Each of the header pipes is a hollow solid body produced by an extrusion of an aluminum material and having a flat section and a rounded section. The flat section includes a plurality of apertures for receiving the tubes and is thicker than the rounded section. Top and bottom support beams are not only brazed to the outermost corrugated fins but also jointed at their opposite ends to the flat sections of the header pipes. A plurality of brazing beads braze and liquid-tightly joint the opposite ends of the tubes to the first and second header pipes. The brazing beads are formed by melting in a brazing furnace a pair of brazing metal plates respectively interposed between the opposite ends of the tubes and the header pipes. This heat exchanger is prevented from burst, deformation and refrigerant leakage.

Abstract: A heat exchanger has two collecting pipes and a streamlined-section tube matrix connected with these two pipes. The collecting pipes comprise several thin sheet metal shells connected with one another which permits simplified and higher speed manufacture of the collecting pipes, particularly since manufacture of cutouts in the collecting pipes for fitting through the small streamlined-section tubes, which is otherwise very time-consuming, can be significantly simplified.

Abstract: 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 intent 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.

Abstract: An arrangement for soldering aluminum objects which are coated with solder, especially coolers and heat exchangers, comprises at least one oven section and a cooling chamber. A transporting arrangement, especially a carriage, advances the objects to be soldered in succession through the oven section and the cooling chamber. A heating arrangement and a controllable blower are arranged in each of the oven sections provided, being operative for directing heated air against the objects advancing through the respective oven section. A first temperature sensor measures the temperature upstream of the objects as considered in the flow direction of the heated air, while at least one second temperature sensor is arranged at the opposite side of the object from the first sensor and is operative for measuring the temperature of the air that has been discharged from the object after it has intimately contacted and heated the same. An auxiliary radiation heating arrangement may be provided, so that the objects are heated both by convection heat carried by the air flow that has been heated by the heating arrangement, and by radiation heat emanating from the radiation heating arrangement to thereby achieve a uniform temperature increase and thorough heating of the object from both sides.

Abstract: This invention relates to a heat exchanger structure in which a passage for the cooling or heating fluid is formed. The inner surface of the passage is roughened, and provided with a plurality of lengthwise-extending, inwardly-projecting, linear or spiral, continuous or intermittent fins. The cooling or heating fluid is passed through the passage to promote an increase in the heat exchange rate. In order to manufacture such a heat exchanger structure, a pipe provided on its inner surface with a plurality of lengthwise-extending, inwardly-projecting, continuous or intermittent fins is inserted between a plurality of complementary members to combine these parts in the shape of a mold. The exposed portions of the joint surfaces of these complementary members and such portions of the complementary members and pipe are then hermetically vacuum-sealed. The resultant complementary members and pipe are diffusion-welded unitarily by the hot isotropic pressure welding. A nickel plate or a nickel alloy plate or a stainless steel plate, which is laminated on the portion of the assembled parts which requires to have the wear resisting properties is also diffusion-welded at the same time.

Abstract: An improved plate-type heat exchanger and a method for joining the plates thereof is disclosed. The heat exchanger includes a core containing a plurality of spaced parallel plates. The core is attached to the housing of the heat exchanger by means of a spray weld process and a standard weld process. In the spray weld process a filler metal is deposited on the core and the housing frame at the joint where the end portion of the plates and the housing frame meet. The filler metal used in the spray weld process forms a spray weld fillet which increases the thickness of the plates. The standard weld process further secures the plates to the heat exchanger housing frame.
