  • Patent number: 10500673
    Abstract: In a main metal piece 60 and an inner cylinder 70 serving as cylindrical bodies before welding, a second end surface 75 is an inclined surface that inclines toward an end portion opposite from the second end surface 75 as the second end surface 75 extends toward the center axis, and an angle ?2a is 5° to 15°. Thus, the distance between a first end surface 65 and the second end surface 75 positioned in resistance welding increases toward the center axis, and an angle ?c (=angle ?2a) between the first end surface 65 and the second end surface 75 is 5° to 15°.

    Abstract: A variety of methods of forming polymer manifolds and the resulting manifold structures are described. The described manifolds are well suited for use in heat exchangers and a variety of other applications. In one aspect a polymer manifold includes a multiplicity of tubes having first ends that are received by a manifold housing. A polymer film is secured to the manifold housing and to the ends of each of the tubes. The film is arranged to seal the housing while leaving the openings of the tubes exposed to thereby create a manifold. In some embodiments, a potting material is used to reinforce the film. In a method aspect, a manifold may be formed by positioning first ends of the tubes in a manifold housing and welding a polymer film to the manifold housing and to distal tips of the tubes. Openings for the tubes are then formed in the film by directing heat towards the film which melts or vaporizes the film in the regions of the tube openings.

    Abstract: The present invention provides a system and method that allows use of the same or similar material as the flow tubes for the supports and without requiring more expensive stainless or higher alloy supports. The disclosure provides one or more temperature moderated support tubes that allow the process fluid in the flow tubes to also pass through the support tubes. The benefit is that the process fluid moderates the temperature of the support tubes and hence the thermal expansion of the support tubes to be relatively consistent with the expansion of the flow tubes of the coil, and further benefits from additional heat transfer area using the support tubes. Thus, the support tubes can be made from the same or similar material as the flow tubes. The ledges/brackets could be also of the same material as the coil material.

  • Patent number: 8408284
    Abstract: A heat exchanger assembly that includes an outlet header/manifold defining an outlet cavity, an outlet tube in fluidic communication with the outlet cavity, and a heat exchanger core. The outlet tube and the outlet cavity cooperate to reduce a temperature value range across the heat exchanger core by equalizing refrigerant distribution between the refrigerant tubes within the heat exchanger core. The length of the heat exchanger headers/manifolds may be increased for a predetermined packaging width because the outlet tube and inlet conduit may exit the headers/manifolds perpendicularly rather than axially, allowing the heat exchanger core width to be increased. The increased heat exchanger core width allows additional refrigerant tubes to be included in the heat exchanger core, providing decreased air pressure difference for air flowing through the heat exchanger assembly and increased heat capacity of the heat exchanger assembly.

  • Publication number: 20120305229
    Abstract: A heat exchanger and related methods are provided. An example heat exchanger has moveable or flexible joints between tubular members that contain flowing heating medium. The moveable joints allow the overall structure of the heat exchanger to adapt to expansion, contraction, and other stresses of high-temperature, high thermal-gradient operation. The moveable joints also provide breaks in the structure, enabling repair or replacement of parts. A negative internal pressure is maintained to prevent flue gases and heat from escaping through the moveable joints, and prevents contamination of the ambient environment and products being dried. Moveable support measures also allow each tier of tubes to expand or contract independently of each other to accommodate thermal gradients within a given tier of tubes, within a given manifold, and between tiers of tubes, so that virtually all of the thermal stresses associated with conventional heat exchangers are mitigated or eliminated.

  • Patent number: 8276401
    Abstract: An evaporator includes a refrigerant inlet header section, a refrigerant outlet header section, and a refrigerant circulation path connecting the two header sections. A refrigerant inlet-outlet member composed of a first plate, a second plate, and an intermediate plate is joined to the two header sections. The refrigerant inlet-outlet member has an inflow channel whose one end communicates with the refrigerant inlet of the refrigerant inlet header section and whose other end is opened to a rear edge of the refrigerant inlet-outlet member, and an outflow channel whose one end communicates with the refrigerant outlet of the refrigerant outlet header section and whose other end is opened to the rear edge. The first and second plates each have inflow-channel-forming and outflow-channel-forming outward swelled portions. Cutouts and a through hole are formed in the intermediate plate such that the inflow channel and the outflow channel cross each other.

  • Patent number: RE45113
    Abstract: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.
