Definitions

  • the invention relates to a collector for the liquid phase the working medium of an air conditioner, with a first and second connection channel, with diametrical distance and parallel vertical to each other through a massive head-end wall a provided for vertical arrangement, cylindrical Collector containers are guided and with a with the second connection channel connected Leitrohrsystem, the is guided through the interior of the collector tank and with a deflection passes through the bottom area and be End piece in the upper region of the header container opens open, wherein the guide tube system in the region of the deflection at least has an opening for the return of collected oil in the Cycle of air conditioning.
  • a collector of this kind is known by EP 1046872. Since the Inflow opening of the open end of the guide tube this Collector the head-side inflow channel arranged opposite is, the open tail is enclosed by a hood, the also a deflection of the inflowing medium to the container wall and down. A separation of the liquid Phase and in particular their oil content is by such Flow control not favored. A use of this collector for higher pressures and with reverse flow direction is not scheduled.
  • the invention has for its object to find a collector of the type mentioned, which has an improved separation efficiency with a simple structural design and is particularly suitable for the heating operation of a CO 2 air conditioning.
  • the collector 1 for the liquid phase 2 of the working medium An air conditioner has a cylindrical, for the vertical Arrangement, preferably in the engine compartment of a vehicle provided Collector tank 3, to which a first and second connection channel 4.5 are provided for the connection of the collector 1 to the pipe system of an air conditioner.
  • the cyclone chamber is opposite the arranged under it, intended for storing the liquid phase Area of the collector tank (3) through an open End piece 9 of the guide tube 6 collar-shaped and circular disk-shaped enclosing and up to a circumferential discharge gap 22 at the cylindrical wall 17 of the header tank 3 reaching horizontal partition 23 shielded.
  • the length of the peripheral opening 19 having pipe socket 18 chosen so that this reaches up to this partition wall 23 and for example closed by this end.
  • the air conditioning whose specific weight is smaller as that of the liquid phase 2 of the working medium, is in Extension of the pipe socket 18 according to the embodiment according to Fig.2 extending through the partition wall 23 Nozzle tube 24 is provided, so that the outlet beam 25 on the surface of the liquid medium accumulated in the container meets and there a floating oil layer with the liquid Phase 2 of the operating medium mixed.
  • This allows the oil over the suction port 11 of the guide tube 6 in the cycle of the air conditioner and thus be returned to the compressor, as in Fig.2 is indicated by the oil drops 27.
  • the designed as a high-pressure tank for a CO 2 air conditioning with heating and thus for a test pressure of much more than 200 bar collector tank 3 has a massive end wall 28 through which the connecting channels extend 4.5, and a relatively thick container wall 20, which after below smoothly merges into a bottleneck-like, massive bottom wall 29, which was made from a previously cylindrical sleeve wall as shown in Figure 7 by material deformation.
  • a massive end wall 28 through which the connecting channels extend 4.5
  • a relatively thick container wall 20 which after below smoothly merges into a bottleneck-like, massive bottom wall 29, which was made from a previously cylindrical sleeve wall as shown in Figure 7 by material deformation.
  • the massive end wall 28 allows a reliable Coupling of coupling blocks 33,34 each a high-pressure pipe connection for connection to the pipe system of the air conditioner.
  • a clamping screw 35 engages in the thread of a Blind hole 36, which in a central, to a greater extent thickened wall portion 37 of the end wall 28 is provided and braces the coupling blocks 33,34 so that provided on them Connecting piece 38,39 with its end face in sealing contact be held with a flat gasket 40,41, on the other hand at the radial surface of an inwardly offset, the connecting pieces 38.39 receiving bore of the connection channels 3.4 is applied.
  • An over the central bottom-side opening 30 connected additional device 32 consists for example of a bursting closure 42 having overpressure protection 43 according to the Embodiment of Figure 1 or from a Berstver gleich 42, remote-actuated accident protection 44 after Fig.2 and Fig.3. Both have a threaded pin 31 having Housing body 45 and 46, the housing space 47,48 at least a transverse to the housing axis directed discharge 49,50 or 51, through which the operating medium after destruction of the bursting stopper 42 can flow to the pressure in the pipe system to suspend the air conditioning within a short time.
  • the burst closure 42 covered with an outwardly arched Closure wall membrane-shaped a central, in the housing space 47,48 and thus to the outflow 49,50 and 51 leading bore 52 and is with a collar-shaped circumferential edge 53 after Type of flat gasket on the front side of a threaded sleeve 54th held in a threaded bore 55 of the thus hollow threaded pin 31 is screwed.
  • this has an internal engagement profile 56.
  • a substantial amount of CO 2 can flow into the passenger compartment as a result of an accidental destruction of the pipe system of the air conditioning vehicle surrounding area
  • Accident protection 44 is provided, is dissipated by the destruction of the bursting closure 42 within a very short time, most of the amount of CO 2 within the engine compartment of the vehicle to the outside.
  • the triggering device 57 for destroying the bursting closure has an explosion body 58, which is arranged on the front side of a housing body 46 enclosed by the plastic body 59 and thus the Berstver gleich 42 opposite.
  • This plastic body 59 encloses an electrical, guided via an electronic control unit 60 trip connection 61 which is connected via an external connection cable 62 with a connector 63 through which the accident protection to the airbag system of the vehicle is connected.
  • an O-ring 64 which bears sealingly against the cylindrical inner surface of the housing chamber 48.
  • the outlet opening of the at least one radially outwardly directed outflow channel 51 to protect the bursting closure 42 against corrosion influences by a housing body 46 enclosing sealing strip 65 is covered.
  • the embodiment of the invention according to Fig.4 to Fig.6 shows a variant for the execution of the guide tube system and for the tangential inflow and central outflow for training the cyclone flow.
  • the draft tube system 66 of this embodiment has an inner tube 67 and an equiaxial to this Outer tube 68, which is arranged in the axis of the header tank 3 ' are and extend into the bottom region 69.
  • the Deflection 70 for the flow is formed by the Inner tube 67 at a distance from the lower, closed end portion 71st the outer tube 68 open ends.
  • the suction port 72 for oil and / or for the liquid phase of the resource is located in the hemispherical lower end wall 73 of the outer tube 68th
  • the open end 74 of the outer tube 68 extends through the dividing wall 23, so that the cyclone flow above the dividing wall 23 can flow through the pipe opening 75 centrally.
  • this guide tube system In the middle region of its axial extent is this guide tube system by three radially extending, flat ribs 76 supported on the inner surface 17 of the header tank 3.
  • connection to the second connection channel 5 extends from the receiving bore 80 for the Connecting piece 39 a second inclined bore 81 through the massive upper end wall 79 of the header tank 3. Since the connection to the inner tube 67 below the for the clamping screw 35th provided blind hole 36 is arranged, has the upper massive end wall 79 of the collector tank 3 a central, inwardly directed, conical extension 82 with an end-side Socket attachment 83 for receiving the inner tube 67.
