  • Patent number: 6874569
    Abstract: Higher heat-exchange capacity and greater vapor-liquid throughflows are attained in a downflow condenser. The increased capacity is achieved by a new design in the manifold to encourage condensation and lessen entrainment of gas phase matter in subcooling flows of condensed liquid. The increased capacity is also achieved by tailoring the flowpaths for a two-phase mixture to avoid reduce liquid film buildup on tubewalls.

  • Patent number: 4546824
    Abstract: There is disclosed a tube-to-header joint arrangement for a heat exchanger wherein the tubes include an oblong or flattened body which is off-set to one side with respect to cylindrical ends formed on the tubes. The off-set bodies facilitate staggering alternate rows of collared openings formed in the header to thereby maintain a predetermined minimum distance between adjacent collars to avoid fatigue or failure of the header, while permitting maximum diameter openings to be employed for maximum surface area contact between each tube and header collar for a stronger joint therebetween.

  • Patent number: 4546825
    Abstract: The drawings and description disclose a heat exchanger including two half circle shells, each having corrugated walls, with the half circle shells being welded together at their mating edges to form a full round shell. Prior to the welding operation, a perforated header is mounted in the half shells in the first corrugation adjacent each end thereof, and a plurality of perforated baffles are mounted within the half shells intermediate the headers in corrugations at alternate equally spaced intervals therein. The perforations in the headers and baffles are formed to be aligned, and a tube is mounted through each series of aligned openings to form a tube bundle within the half shells. The two half shells are welded together at their mating edges to form the full round shell, and the headers are brazed to the shell and the tube end portions brazed to the headers.

  • Patent number: 4546823
    Abstract: There is disclosed herein a radiator wherein grooves formed in a tank flange and in a header match each other and a mound formed on an associated clamping strip. Tapered edges formed on locking tabs cut in the tank flange cooperate with a sloped surface on the clamping strip when bent inwardly to urge the clamping strip and header toward the tank flange so as to compress a sealing gasket between the header and tank flange grooves, eliminating the need for solder.

  • Patent number: 4485867
    Abstract: There is illustrated and described herein a heat exchanger including rows of tubes, a pair of headers secured to the ends of the tubes, a groove formed in each of the headers adjacent the peripheral wall thereof and intermediate adjacent rows of tubes, a recessed portion formed along the full length of the centerline of each groove, a pair of tanks having walls aligned with and mounted in the grooves of the respective headers, a ledge formed around the outside wall of each header, a chamfer formed along each of the inner and outer edges of the tank walls to form a blunt edge at the ends of the chamfers, and a gasket mounted in each groove and depressed along its centerline into said recessed portions by the blunt edge, the tanks being retained in position by bending spaced extensions of the peripheral wall of each header onto the ledge.

  • Patent number: 4458749
    Abstract: The drawings and description disclose a radiator having top and bottom tanks with their respective headers, and a core assembly therebetween. The latter includes a group of fins and tubes, wherein each tube has a flattened, oblong body section, cylindrical end sections for connection with the respective headers, and transition sections between the flattened body and the cylindrical ends. Reinforcement means is provided for preventing collapsing or pinching at the ends of the flattened body section due to stressing of the tube or flexing of the headers. The reinforcement means is in the form of various shaped pairs of outwardly extending reinforcement ribs formed on opposite sides of the transition section, or inwardly extending dimples formed on opposite sides of the flattened body section adjacent the transition section.

  • Patent number: 4382464
    Abstract: The radiator illustrated includes a core assembly with a headsheet, gasket and tank bolted on the top and bottom ends thereof, as well as side channels for the opposite sides thereof. A "horseshoe" shaped bracket is secured to the headsheet and tank at each corner of the radiator. Each pair of upper and lower brackets is adapted to having one of the side channels removably mounted thereon and is further adapted to permitting repair of any corner leaks without having to break the tank-to-headsheet sealed joint to remove the side channel therefrom.

  • Patent number: 4332068
    Abstract: A heat exchanger assembly and the method of making same wherein the heat exchanger assembly includes a heat exchanging core having spaced headsheets adjacent opposite extremities with fluid conveying tubes extending between the headsheets and having heat transfer fins disposed upon the tubes. Two plastic radiator components are disposed in mating engagement with one another with each component encasing one-half of the core and disposed in mating engagement with one another and defining spaced open cavities. Each of the components is in fluid-tight or sealed relationship with one another and with each of the headsheets disposed within the opening of each of the cavities so that the cavities and the headsheets define a pair of spaced tanks whereby fluid may flow between the tanks through the heat exchanging core. The headsheets are disposed in grooves within the components with a seal engaging the periphery of the headsheets and disposed in the grooves for sealing the headsheets to the respective components.
