Definitions

  • the present invention relates to an operating fluid unit, comprising a container with a temperature-sensitive vehicle operating fluid contained therein, especially for exhaust-gas treatment, with a container mantle open at least on one side, into which the vehicle operating fluid is introduced and the opening of which is closed by means of a container lid. Furthermore, the invention relates to a method for manufacturing such a container.
  • temperature-sensitive operating fluids such as catalytic or exhaust-gas treatment substances based on metallic hydrides or ammonia, which are generally present in granular or powdered form.
  • sealed-joint connections are required, which, according to the prior art, are manufactured by fusion welding or gluing.
  • fusion welding has the disadvantage of a high input of heat, which can damage the temperature-sensitive operating fluid.
  • gluing is a very time-consuming process which does not allow a rapid manufacturing rate.
  • the object of the invention is to provide a operating fluid unit of the type named, which can be manufactured rapidly and in a manner protective of the operating fluids contained therein.
  • Friction stir welding causes a substantially reduced input of heat by comparison with conventional fusion welding.
  • Magnetic pulse welding magnetic pulse welding, MPW
  • magnetic pulse crimping magnetic pulse crimping, MPC
  • the connecting seam has a distance from the contained vehicle operating fluid. Especially in the case of friction stir welding, any slight input of heat is further reduced before it can reach the vehicle operating fluid by maintaining such a distance relative to the interior of the container.
  • One embodiment of the invention which is particularly preferred for the same reason, is characterised in that the container lid is connected to the container mantle by magnetic pulse crimping with the interposition of a gasket ring into a groove of the container mantle and/or container lid.
  • the connecting seam is disposed at an edge of the container lid facing outwards away from the container opening with a distance from the interior of the container. This achieves a good thermal spacing between the connecting seam and the interior of the container.
  • the edge is profiled on the external peripheral side, preferably tapered, in order to provide a form-fit engagement after the crimping of the container mantle.
  • the container lid is preferably made of sheet metal and the edge is manufactured by reshaping or beading; as an alternative, the container lid is preferably made of cast synthetic material or cast metal, and the edge is made by moulding. Both variants achieve a cost-favourable manufacture.
  • the invention achieves its object with a method for manufacturing a container containing a temperature-sensitive the vehicle operating fluid, especially for exhaust-gas treatment, with the steps of providing a container mantle open at least on one side, introducing the vehicle operating fluid into the container mantle, and closing the container mantle opening by means of a container lid, which is characterised in that the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding or magnetic pulse crimping.
  • FIG. 1 shows, in half section, a first embodiment of an operating fluid unit according to the invention, which is manufactured by friction stir welding;
  • FIGS. 2 a and 2 b show, in fact, in each case in half section, a second embodiment of the operating fluid unit of the invention during two successive manufacturing steps by means of magnetic pulse welding;
  • FIGS. 3 a and 3 b show, also in each case in half section, a third embodiment of the operating fluid unit of the invention during two successive manufacturing steps by means of magnetic pulse crimping.
  • FIG. 1 shows a operating fluid unit 1 comprising a container 2 with a temperature-sensitive vehicle operating fluid 3 contained therein, for example, a granular ammonia salt.
  • vehicle operating fluid 3 can also occupy only a part of the container 2 ; however, by preference, it is firmly pressed into the latter.
  • the container 2 is made up from a container mantle 4 , which is approximately cylindrical in this case, and a container lid, which is inserted into an end opening 6 of the container mantle 4 in a sealing manner.
  • the container mantle 4 can provide any required cross-section and can also have more than one container opening 6 , each with a container lid 5 . Conventional connections of the container 2 have not been illustrated for reasons of simplicity.
  • the container lid 5 provides a folded edge 7 facing outwards away from the container opening 6 , with which it is in close contact at the internal periphery of the mouth region of the container mantle 4 .
  • a connecting seam 8 is generated between the container mantle 4 and the container lid 5 , in fact, by friction stir welding by means of a fiction stir welding tool 9 , by holding against a contact block 10 .
  • the connecting seam 8 preferably maintains a distance A from the interior of the container and accordingly from the vehicle operating fluid 3 contained therein.
  • the distance A is preferably within the range from 1 to 50 mm, by particular preference 3 to 20 mm.
  • the container lid 5 in an inverted manner, that is, with the edge 7 facing inwards into the container mantle 4 , in which case, the distance A does not occur.
  • FIGS. 2 a and 2 b show a further alternative embodiment and an alternative manufacturing method for the operating fluid unit 1 .
  • the container lid 5 here is a cast synthetic material or cast metal part with an edge 7 moulded or formed by milling, with a slight conical tapering at the external periphery.
  • a magnetic pulse welding method magnetic pulse welding, MPW
  • MPW magnetic pulse welding
  • FIGS. 3 a and 3 b show a further embodiment, in which the external side of the edge 7 is profiled, especially tapered, facing in the direction away from the container opening 6 , and the connecting seem 8 is provided by form-fit folding of the mouth region of the container mantle 4 onto the profiled edge 7 by means of a magnetic pulse crimping method (magnetic pulse crimping, MPC).
  • MPC magnetic pulse crimping
  • an O-ring gasket can be inserted between the container mantle 4 and the container lid 5 , and, in fact, into a groove 12 of the container mantle 4 and/or of the edge 7 .
  • the container lid 5 can also be provided with a moulded sealing lip.
