  • Patent number: 6722422
    Abstract: A heat exchange system utilizing flow reducers at 180 degree bends in the tubes includes a first set of media tubes in which heating/cooling media flows, and a set of product tubes positioned concentrically within the media tubes and in which liquid product flows in a counter direction to the heating/cooling media. The tubes are arranged in a serpentine, back and forth manner, and U-shaped tubes interconnect successive pairs of product tubes to achieve the 180-degree change in flow direction. The U-shaped tubes are of a cross-sectional diameter greater than the product pipes. Tapering flow reducers extend between the opposing ends of the U-shaped tubes and the product tubes. The exit flow reducer is eccentrically formed to facilitate a smooth transition of the product from the U-shaped bend to the product tube and prevent liquid product from becoming entrapped along the bottom of the flow reducer.

  • Patent number: 6390185
    Abstract: An annular flow concentric tube heat exchanger for heating two counter flowing fluid streams has been devised. Although capable of heating gases or liquids, the primary purpose of the invention is to function as an improved recuperator for recovering exhaust heat from a Brayton Cycle gas turbine engine, Ericsson Cycle engine or similar recuperated engine. The basic element of the recuperator is a concentric tube assembly that, in the preferred embodiment, is comprised of four concentric tubes that enclose three concentric annular flow passages. The low pressure exhaust flows through the inner and outer annular passages while the high pressure compressor exit air flows through the annular passage that is between the two low pressure passages. The high and low pressure flows are in opposite directions to achieve the high effectiveness that is only available with a counterflow heat exchanger.

    Abstract: A heat engine is constructed from sheet metal and the like. The heat engine has an outer container and inner container which contains a displacer and a power piston. A plurality of positioning members are provided to dimensionally stabilize the inner and outer containers. By providing positioning members that extend between the inner and the outer containers, a sandwiched construction is obtained which allows the inner and outer containers to reinforce each other thus permitting the use of thin walled containers and improving the thermal efficiency of the heat engine and decreasing the weight of the heat engine.

  • Patent number: 5107919
    Abstract: An improved air dryer for pneumatic systems (10). The improved air dryer (10) employs air-to-air and an air-to-refrigerant heat exchanger portions (12-14) that are substantially parallel and coextensive. Each heat exchanger portion (12-14) is made up of a plurality of tube units (16-52), each tube unit (16-52) having three concentric tubes (22-24-26-58-60-68). The intermediate tube (60) of the air-to-refrigerant portion (14) includes a helically deformed central portion (66) to increase surface area and create turbulence within adjacent passageways (70-74). The tubes (16-52) terminate at each end in separate header units (34-40-46-80-86-92). Incoming air is passed co-currently, then countercurrently, in the-air-to-air portion (12) with air that has been dried, whereupon a pre-cooling stage is achieved. This pre-cooled air is then passed counter-currently, then co-currently, to refrigerant in the air-to-refrigerant portion (14) for causing condensation of moisture therein.
