Definitions

  • the present invention relates to exhaust gas coolers and methods of making and using same.
  • the high temperature of the exhaust gas that enters an exhaust gas cooler combined with the cyclic nature of the gas flow creates a thermal stress within the cooler core. This will lead to fatigue failure depending on the temperature and number of cycles. A way to reduce the stress in the core is required in order to prolong the of the cooler.
  • the present invention provides a solution that is much less complicated and does not require the sliding arrangement of the prior art, as well as providing additional benefits, namely an intermediate seal or gasket between the header plate and the individual tubes of the exhaust gas cooler. While other heat exchangers are known to have a gasket between the tubes and header to form a seal, the gasket on these units is to allow a unit to be assembled without brazing. Like gaskets are used at both ends of the tubes. The present invention is still brazed, but the seal allows for thermal expansion of non-brazed tube ends.
  • the cooled medium of the invention is exhaust gas through the tubes cooled by coolant over the tubes,
  • the present invention is of an exhaust gas cooler and a method of manufacturing an exhaust gas cooler, comprising: providing a shell; disposing within the shell a tube bundle/core through which exhaust gas passes; and situating a seal or gasket assembly providing a liquid-tight sea! between the shell and the tube bundle/core and between each tube of the tube/bundle core, in the preferred embodiment, the seal or gasket assembly is situated proximate an end of the tube bundle/core, most preferably proximate the cold end of the tube bundle/core.
  • the seal or gasket assembly preferably comprises a seal or gasket comprising one or more of rubber, silicone, and a polymer, and the assembly preferably comprises a header between the shell and the seal or gasket.
  • the seal or gasket preferably comprises a notch accepting the header and has a rounded interior profile.
  • the tube bundle/core preferably comprises tubes with unbrazed ends.
  • the tubes are preferably flared and have fins recessed to accommodate the flared ends,
  • Fig. 1 is a front perspective view of an exhaust gas cooler according to the invention.
  • Fig. 2 is a front perspective detail of the invention shown in Fig. 1.
  • the present invention allows the tubes of an exhaust gas cooler to expand and contract without restraining them within the core bundle. This is achieved by the use of an intermediate seal or gasket between the header plate and the individual tubes.
  • the seal prevents coolant from leaking out of the cooler and lets the tube length increase and decrease with the variation of the exhaust gas temperature.
  • the seal is applied to the cold end of the core, where the temperatures are low enough on the tube wall to allow a polymer to be used without degradation over time.
  • the geometry of the arrangement also encourages corrosive condensate to run away from the seal.
  • the cooier core is preferably brazed before assembly of the gasket seal onto the tubes.
  • the gasket is preferably pushed over the tube ends and through the header. After assembling the gasket onto the tubes and header plate the tube ends are preferably expanded (flared) to resist the tendency of the pressurized coolant to force the gasket off the ends of the tubes.
  • the fin In a cooler with a secondary surface within the tubes the fin are preferably recessed within the tube to allow passage for the expansion punch.
  • the exhaust gas cooler 10 of the invention comprises shell 12, tube bundle/core and seal or gasket 16 .
  • the seal preferably comprises rubber, silicone, or polymer able to withstand the temperature ranges expected to be encountered by the particular exhaust gas cooler at issue.
  • Inset 18 of Fig. 1 is shown in detail in Fig. 2.
  • Header 20 is placed within the shell and fits into a corresponding notch in the seal or gasket, forming a seal or gasket assembly.
  • It fins 24 are employed within one or more tubes of the tube bundle/core, then the fins are preferably recessed to allow for flaring 22 of the tubes at the ends with the sea! or gasket.
  • the seal or gasket preferably has a rounded profile on its interior, as shown In Fig. 2, to ease insertion onto the tube bundle/core.
