Definitions

  • the invention relates to a heat exchanger with at least one connection element according to the preamble of claim 1.
  • the invention also relates to a Process for the connection between heat exchanger and Connecting element.
  • a stacked heat exchanger is e.g. B. from DE 93 09 741 known.
  • This heat exchanger consists of trough-shaped, nested Stacking washers and end plates. The components are soldered together and in this way result in a dense system towards the outside. Inlets and outlets are for the coolant circuit and for the circuit of the fluid to be cooled intended.
  • the heat exchanger is at least one of the end plates as Flange formed.
  • This can be provided with holes and z. B. with help be fastened by screws at the intended installation location.
  • Disadvantage of this The solution is the additional process of providing the hole in the end plates. There must also be a hole at the installation location, possibly with provided with a thread. Even as a fastener The screws used mean an additional outlay on components.
  • the heat exchangers are usually manufactured in an oven. With Components of the heat exchanger coated with a solder material become loose pre-assembled and provisionally fixed. There is a temperature in the oven at which the Solder material melts and flows into the connection points of the individual components. On in this way the components are connected and the Liquid circuits sealed against each other and against the environment.
  • WO 86/05866 also describes a heat exchanger, the connection between connection and heat exchanger are produced by deformation got to.
  • the object of the invention is a combination of heat exchanger or to create its connecting elements, the manufacturing costs the assembly effort or the functional reliability is optimized.
  • the combination of heat exchanger and connection element according to the invention has a link mechanism that consists of holding devices on There is a heat exchanger with receptacles on the connection elements interact. Additional connecting means such. B. screws are not necessary.
  • the holding device are designed as part of the housing.
  • the holding device and the receptacles have a simple geometry.
  • the Recordings can therefore already in the master tool of the connection elements be provided. This eliminates additional operations such. B. provide for that of holes that are not provided in the master tool without undercuts can be gone.
  • Holding device by deformation of certain parts of the heat exchanger, especially the end plates.
  • the end plates are in general stamped parts and are often provided with beads to stiffen them. These process steps can also be carried out without additional manufacturing effort Holding device are integrally formed on the end plate. By providing Holding devices of this type therefore generate almost no additional effort.
  • Another variant of the holding device which is not claimed consists of profiled strips which are fixed to the Housing are soldered.
  • the profile strips can be inexpensively Manufacture semi-finished products. You can with insignificant Additional effort in the loosely preassembled stacked plate package of the heat exchanger to get integrated.
  • the treatment in the oven creates between the profile strips and the housing a firm connection.
  • Treatment of the heat exchanger in the Oven is a manufacturing step that is due to the stacked disc structure of the Heat exchanger results. So there is no additional one in this variant Process step for fixing the holding device to the heat exchanger necessary.
  • connection elements are made of plastic, the inherent elasticity of this material be used, e.g. B. by providing elastic snap noses.
  • a provision of locking has the advantage that the connection between connection elements and heat exchanger can be made detachable.
  • connection elements correspond with each other.
  • This can, according to the invention, for. B. can be solved in that grooves or flanges be provided on the connecting element, which with the holding devices on Heat exchangers are engaged. Is it the connecting elements z. B. around oil filters with essentially symmetrical geometry, they can Grooves or flanges through a shape division running through the axis of symmetry Manufacture without undercuts.
  • the connector is provided on the Installation site brought to the heat exchanger. Then the Holding devices plastically deformed, e.g. B. by bending. This creates a Positive connection between the connection element and the heat exchanger. The connector remains largely undeformed.
  • connection between the heat exchanger and the connecting element is cannot be removed unless the holding device is brought into its original shape back.
  • the assembly process is due to deformation of the holding elements very economical, especially for large quantities.
  • the assembly can be done mechanically take place in a device provided for this purpose.
  • a heat exchanger 10 is shown with connection elements 11.
  • the Connection elements can, for. B. an oil filter 12 or the mounting location in the engine compartment, for. B. the engine block or the oil pump.
  • the heat exchanger has one Coolant inlet 13 and a coolant outlet 14, which in this case as Hose connectors are designed for coolant hoses, not shown.
  • the Connection elements are available via an inlet 15 and an outlet 16 for the cooling fluid in connection with the heat exchanger.
  • connection elements 11 and the heat exchanger 10 are due to an interaction of holding devices 17 on the end plates 18 of the heat exchanger 10 and receptacles 19 on the connection elements 11 guaranteed. Different variants of this connection are shown in the following Figures described in more detail.
  • FIG 2 is a mounted connector 11 on a heat exchanger in the Section shown.
  • the heat exchanger is trough-shaped stacking disks 21 formed on their contact surfaces 22nd are soldered together. Furthermore, there is a contact surface between the top stacking disc and the end plate 18, which completes the Forms heat exchanger and also a soldered contact surface 22 has the top stacking disc.
  • An edge 23 is at the edge of the end plate folded outwards and thereby forms one of the holding devices 17.
  • a second holding device is formed by a profile strip 24, which is also a Has contact surface 22 with the end plate 18, via which it is soldered.
  • the edges 23 of the holding devices 17, one of the holding device being Profile bar 24 is shown in dashed lines in Figure 2. These positions take the edges before installing the connector 11.
  • the Connection element is inserted between the holding device and the edges of the Holding device bent.
  • the holding devices 17 are shown in FIG assembled state of the connecting element 11 shown.
  • the holding devices are with the receptacles 19 of the connecting element 11 in Connection.
  • FIG. 3 shows an alternative, not claimed geometric configuration of the holding device shown. Similar to that shown in FIG. 2, this consists of a profile strip 24, which is soldered to the end plate 18 via the contact surface 22. The one in Legs 26 protruding from the surface of the end plate 18 of the holding profile 24 is partially cut out. The cut parts 27 can after insertion of the connecting element 11 by plastic deformation in it provided grooves 28 are pressed into the connecting element. The groove assumes the function of the receptacle in the connecting element 11.
  • FIG. 5 a version of the holding devices 19 is shown, which as Bayonet lock is formed.
  • the holding devices are, similar to that in FIG. 2 shown, formed from the end plate 18 and the profile strip 24.
  • the filter 12 has a flange-like approach that takes over the function of the receptacles 19. So that the oil filter can be placed between the holding devices, the flange-like approach recesses 29.
  • the oil filter can be in a designated Guide 30 are used.
  • the receptacles 19 come into engagement at 90 ° under the holding devices 17. there engages a lock 31, which by corresponding indentations 32 in the Holding device or in the oil filter is formed.
  • FIG. 6 shows a further alternative embodiment for the holding device which is not claimed. This exists from a socket 33, the z. B. is soldered into the inlet 15.
  • the oil filter 12 is with its inner opening 34 pushed onto the socket, this by plastic Deformation clamps the oil filter.
  • the edges 23 before the assembly Deformation of the socket 33 is shown in dashed lines in FIG. 6.
