Definitions

  • the invention relates to a water / air cooler according to the preamble of claim 1.
  • a water / air cooler of this type is known (FR-A 2 465 986).
  • the expansion tank provided there made of plastic is attached to the upper water tank by means of two elastic claws arranged approximately in its center.
  • the expansion tank sits on two pegs that protrude upwards from the water tank, which is also made of plastic, with corresponding recesses.
  • the side claws have locking hooks at the free end, which engage behind corresponding projections in the middle of the length of the water tank.
  • the connection from the water tank to the expansion tank is made via two tubular connecting pieces, which each engage in openings of the water tank provided with seals.
  • the invention has for its object to perform the attachment of the expansion tank on the water tank more stable despite easy installation.
  • the characterizing features of claim 1 are provided in a water / air cooler of the type mentioned. This configuration makes it possible to attach the expansion tank only for pressing the connecting pins and the locking hooks into the assigned openings. Alignment of the position is not necessary.
  • the laterally protruding locking eyelets act as lateral brackets, which form additional support surfaces for the expansion tank and are thus able to safely absorb any tilting moments that may occur.
  • the direct assignment of the locking hooks to the hollow spigot which can already provide excellent positional protection, also ensures a firm connection between the water tank and the expansion tank, which also ensures tightness.
  • claim 3 offer security against unwanted loosening of the locking hook.
  • claims 5 to 8 allow to use the stable hollow connector arrangement according to claim 4 at the same time to establish the fluid connection between the water tank and the expansion tank, so that in addition to the easier attachment of the expansion tank also simplification occurs in that insofar as the attachment of a separate Connection line becomes unnecessary.
  • claims 10 to 12 enable a stable arrangement of the expansion tank on the water tank, with which acceleration forces can be absorbed, which occur transversely to the cooler through which the headwind flows.
  • the arrangement is such that one of the two hollow socket assemblies forms a floating bearing in the longitudinal direction of the water tank, so that movement expansion is possible due to thermal expansion due to different materials, without the position adjustment of the expansion tank being impaired.
  • the upper area of a water / air cooler (1) with the upper water tank (2) is shown, the two side parts (31 and 32) with the lower water tank, not shown, and with the between the two Water boxes arranged, also not shown finned tube block is connected.
  • the water tank (2) which in the exemplary embodiment is made of plastic, for example glass-fiber-reinforced polyamide, an expansion tank (4) is placed, which is also made of plastic, for example polypropylene.
  • the water / air cooler (1) which is preferably suitable for a commercial vehicle, can be attached to the vehicle in the usual way.
  • the side parts (31 and 32) are connected to the longitudinal beams of a vehicle frame, a third attachment point being in the middle of the upper water tank (2) and being connected to a holder screwed to the vehicle engine via a rod (not shown).
  • the rod can penetrate the water space of the water tank (2) at the point (33), where a piece of pipe with a square cross section firmly in the What serkasten is used, which seals the water space.
  • the expansion tank (4) is attached to the water tank via hollow connectors (5 or 6), of which the hollow connector (5) is assigned to the expansion tank (4) and the hollow connector (6) to the water tank (2).
  • the hollow connectors (5 and 6) are designed so that they fit into one another. They each form a bowl which, as will be described in detail with reference to FIG. 3, is in each case inserted into the associated bowl of the other part.
  • the expansion tank (4) are also assigned latching hooks (7) which are integrally molded onto the expansion tank (4) and which lie diametrically opposite the axis (27) of the connecting piece (5) of the expansion tank (4). The locking hooks (7) in the position shown in FIGS.
  • locking eyelets (8) which are firmly connected to the plastic water tank (2) and are preferably also integrally molded on this plastic water tank.
  • These locking eyelets (8) are in the form of laterally projecting tabs with rectangular channels through which the relatively wide locking hooks (7) with their clamping lugs (34) provided at the lower end project.
  • the clamping lugs (34) are provided with contact webs (35) which bear against a counter-latch (36) in the inserted position, which prevents the clamping lugs (34) from being inadvertently in the latched position detach from the lower edge (15) of the eyelets (8).
  • the configuration is such that the counter detents (36) are provided with inclined run-up surfaces for the contact web (35), which also contribute to the clamping lugs (34) of the detent hooks (7) engaging behind the edge (15), when the expansion tank (4) is placed on the nozzle (6) of the water tank (2).
  • each of the hollow connecting piece (5 and 6) consists of two concentrically arranged collars (9 and 10) (for the hollow connecting piece (5)) and (11 and 12) (for the hollow connecting piece (6)) , which each leave an annular gap (13) or 14) between them, into which the collar assigned to the other hollow connector can be firmly inserted.
  • the arrangement is such that the inner collar (9) of the hollow connector (5) is held in the annular gap (14) between the collars (11 and 12) of the hollow connector (6), while the outer collar (12) of the hollow connector (6) is held in the annular gap (13) between the collars (9 and 10).
  • the inner collar (11) of the hollow socket (6) also sits in a further annular gap (37), which is formed by the collar (9) and an inner ring socket (38) on the expansion tank (4).
  • This configuration creates a stable connection in all directions deviating from the axis (27) by pushing the hollow connecting pieces (5 and 6), which secures the position of the expansion tank (4) with respect to the axis (27) on the water tank (2).
  • the hollow connections (5 and 6) can be freely moved in the direction of the axis (27). The locking in this direction is taken over by the locking hooks (7) and the locking eyelets (8).
  • a second hollow socket arrangement for securing the position of the expansion tank (4) is also provided, in which locking hooks (7) and locking eyelets (8) in the diametrically to the axis (27 ') same design as in Fig. 3 are provided.
  • a floating bearing is formed in the exemplary embodiment, which interacts with the fixed bearing shown in FIG. 3.
  • a hollow pin (21) is provided which engages in a groove (22) on the expansion tank, the width shown in Fig. 4 is selected so that it corresponds to the width of the hollow connector (21), the Fig. 5 apparent length (1) but greater than the length of the hollow connector (21) measured in the same direction.
  • FIGS. 1 to 5 therefore enables a very simple assembly of the expansion tank (4) on the water tank (2), but also secures the position and ensures an extremely stable connection between the water tank (2) and the expansion tank (4).
  • the new arrangement is therefore particularly suitable for water / air coolers, such as those used for commercial vehicles, where the stress is relatively high.
  • FIG. 6 shows a modified embodiment of the connection between the expansion tank (4) and a plastic water tank (2), in which the cup-like interlocking of collars (9 ', 10', 11 'and 12') of two hollow sockets is also shown (5 and 6) is provided, which is intended to secure the position with respect to the axis (27), but in which both hollow connectors (5 and 6) are each provided with a passage opening (17) which provides a fluid connection between the interior of the water tank (2) and the interior of the expansion tank (4).
  • the edge (9 ') of the hollow connector (5) penetrates into the Annular gap (14) when the expansion tank (4) is pushed onto the water tank (2) in the direction of the axis (27).
  • the collar (12 ') is pushed into the annular gap (13) and the annular connector (38') penetrates into the cylinder space (39) inside the collar (11 ').
  • the dimensions are chosen so that the walls of the collars to be pushed into each other touch, so that after pushing one another they form a dense labyrinth, which in addition to securing the position of the expansion tank (4) on the water tank (2) also for sealing the fluid connection between the expansion tank (4) and water tank (2). It is also still possible to provide sealing rings (18) which come to rest on shoulders (19 or 19a) and additionally ensure a good seal. Corresponding sealing rings (18) can of course also be provided in the embodiment of FIGS. 1 to 5, where, however, they do not need to produce the sealing effect, but because of their installation they can then provide damping when absorbing acceleration forces.
  • the remaining structure of the arrangement according to FIG. 6 with regard to the locking eyes (8) and the locking hooks (7) corresponds to that of FIG. 3.
  • FIG. 7 another variant is shown in which the hollow connecting piece (5 or 6) is also shown.
  • the expansion tank (4) or water tank (2) are simultaneously designed as a liquid connection.
  • a hollow collar (6) in the area of the inner collar (11 ") is also assigned a flange (40) projecting inwards like a flange, in the opening of which a valve (20) is inserted.
  • This valve (20) is used
  • the remaining latching by latching hooks (7) and eyelets (8) which is no longer shown here in FIG. 7, corresponds to that of FIGS. 1 to 5.
