Definitions

  • the field to which the disclosure generally relates to includes retention device.
  • Retention devices may be used in a variety of applications.
  • Document EP 2 522 941 A1 which is considered as the closest prior art, discloses a device for reducing vibrations of a tube core of a heat exchanger inside a shell. The device allows a secure and quick insertion after the core has been manufactured and yields that high temperatures - to which the core is subjected for the attachment by means of brazing - do not affect the properties of the device, particularly the elasticity achieved by means of tempering. It is an object underlying the present invention to provide products with a retention device having an improved retention reliability and easy handling.
  • a product according to independent claim1 and alternatively by a product according to independent claim 7.
  • Preferred embodiments are defined in the respective dependent claims.
  • a number of variations may include a product comprising a retention device comprising a plurality of members, including an arch member and a spring member defining multiple contact points.
  • Oxides of Nitrogen (NOx) and particulate matter are two components of the engine exhaust emissions that must be controlled.
  • EGR exhaust gas recirculation
  • the engine 1 may have an intake manifold 2 and an exhaust Manifold 3.
  • the EGR system may include an exhaust gas recirculation (EGR) valve 4 that controls the flow of exhaust gas to intake manifold 2.
  • the heat exchanger 5 may be used to reduce the temperature of the exhaust gas.
  • Conduits 6, 7, 8, 9 and 10 may provide the interconnection between the exhaust manifold 3, heat exchanger 5, EGR Valve 4, and Intake manifold 2.
  • the system shown may use an electrically controlled EGR valve.
  • An electronic control unit (ECU) 11 may provide a signal that will control the opening/closing of the valve. As the EGR valve opens and closes it will increase or decrease the flow rate of exhaust gas to the intake manifold.
  • a throttle valve 12 may be provided to control airflow into the intake manifold.
  • a portion of the exhaust gas may be recirculated back to the intake manifold where it will be combined with incoming air and fuel.
  • the exhaust gas portion of the mixture does not support combustion and when this mixture is compressed and ignited in the cylinder, the inert exhaust gas will control the combustion temperature and limit the formation of NOx and particulate in the exhaust.
  • the temperature of the recirculated exhaust gas may be a factor that determines the effectiveness of the NOx and particulate reduction. It is common for an EGR system to include a heat exchanger to remove heat from the exhaust gas and provide an optimize exhaust gas temperature for controlling emissions.
  • FIG. 2 One type of heat exchanger 13 is shown in Figures 2, 3 , and 4 . It may include a number of tubes 15 in a rectangular array 16. Tube 15 may have an inner surface 29, wall 30, and outer surface 25, as shown in Figures 3, 3A View A and 4. This rectangular array 16 may also be referred to as the core and exchanger 13 may include one or more cores.
  • the tubes 15 may be made of a metal such as stainless steel, aluminum or other suitable material.
  • the core 16 may include metal headers 17 and 18 located at either end of the tubes 15.
  • the headers 17 and 18 may also be made of a metal such as stainless steel, aluminum or other suitable material.
  • the tubes 15 may be secured and sealed to metal headers 17 and 18 by brazing, soldering, or other suitable means.
  • the core 16 may be placed in a housing 14 and may be sealed into the housing by a gasket 19, O-ring 20 or other suitable means. At one end, header 18 may be attached to a cone 21 to transition to the O-ring seal 20. Housing 14, core 16, cone 21, gasket 19, and O-ring 20 may define a sealed space 22 within the housing 14. Sealed space 22 may be suitable for introducing a cooling fluid 24 that may contact tubes 15 in the rectangular array 16. Header 17 and gasket 19 may have a first opening 23 to allow a cooling fluid 24 to flow into sealed space 22. Cooling fluid 24 may contact the outer surface 25 of tubes 15. Header 17 and gasket 19 may also have a second opening 26 that may allow cooling fluid 24 to exit sealed space 22.
  • a fluid or gas 27 may enter tubes 15 from a first end 28.
  • the fluid or gas 27 may be exhaust gas from an internal combustion engine.
  • the exhaust gas 27 may be at a first temperature, for example 600°C.
  • Exhaust gas 27 may flow through tubes 15 and may exit at a second end 29.
  • Cooling fluid 24 may enter sealed space 22 and may contact the outer surface 25 of tubes 15 as shown in Figure 3 . Cooling fluid 24 may be at a lower temperature than exhaust gas 27, for example 100°C.
  • the first effect may be the exhaust gas 27 exiting tubes 15 at second end 29 may be at a lower temperature than the exhaust gas 27 entering tubes 15 at the first end 28.
  • exhaust gas 27 entering tubes 15, at first end 28, may be at 600°C and the exhaust gas 27 exiting tubes 15, at second end 29, may be at 200°C.
  • the reduction in temperature may, in part, be due to the transfer of heat from exhaust gas 27, to tubes 15, and to cooling fluid 24 in sealed space 22.
  • the second effect may be the cooling fluid 24 exiting sealed space 22 at second opening 26 may be at a higher temperature than the cooling fluid 24 entering sealed space 22 at the first opening 23.
  • the cooling fluid 24 exiting sealed space 22, at second opening 26, may be at 110°C and the cooling fluid 24 entering sealed space 22, at first opening 23 may be at 100°C.
  • the increase in temperature may, in part, be due to the transfer of heat from exhaust gas 27, to tubes 15, and to cooling fluid 24 in sealed space 22.
  • Both first and second effects may be influenced in-part by parameters such as; the temperature of exhaust gas 27 entering tubes 15, the flow rate of exhaust gas 27, the materials of tubes 15, the wall thickness of tube 15, the length of tube 15, the surface area of tube 15, the fluid properties of the cooling fluid 24 in sealed space 22, the flow rate of the cooling fluid 24 in sealed space 22, or other parameters.
  • a baffle 31 shown in figures 4 and 5 may be located along the length of tubes15.
  • the baffle 31 may be a metal plate with multiple openings 32 that will receive and support tubes 15. Baffle 31 may add support but it may not be sufficient with high levels of vibration that may cause movement of the tubes 15 and the potential for fatigue of the tubes, the brazing joints, or other components.
