  • the invention relates to an exhaust-gas turbocharger according to the preamble of claim 1.
  • An exhaust-gas turbocharger of said type may be equipped with a charger housing which comprises a cooling jacket.
  • Said cooling jacket may in this case be arranged either in the bearing housing, in the compressor housing, in the turbine housing or else in attached regulating elements.
  • a coolant connection is provided which comprises a connection flange.
  • the connection flange in turn has multiple connection fittings, wherein the connection flange is fixed to the charger housing such that the connection fittings are aligned with a respectively associated housing bore in order to be able to produce the required flow connection.
  • an exhaust-gas turbocharger which has a coolant connection with at least one integrated feed pipe and one integrated discharge pipe which, after the installation process, extend through a single connection opening of the charger housing.
  • "Charger housing” refers to a housing part of the exhaust-gas turbocharger, which may be a bearing housing, a turbine housing, a compressor housing and an actuator housing.
  • connection opening or insertion recess in the charger housing can be implemented in a simpler manner, in particular formed as a cast opening which can be produced during the course of the casting of the charger housing.
  • the at least one feed pipe has a bent pipe region which projects into the charger housing or into the cooling jacket thereof, it is made possible for a preferred flow direction to be imparted to the coolant that is fed via the feed pipe.
  • the connection opening or introduction recess in the charger housing can be formed in a simpler manner and, by contrast to conventional known designs, short-circuited cooling that bypasses those regions of the charger housing which are to be cooled can be prevented.
  • the discharge pipe is provided with a rounded inner pipe region which projects into the cooling jacket, it is made possible for pressure losses to be reduced and for the autosiphoning effect to thus be assisted in an effective manner.
  • connection flange For the fastening of the connection flange, it is possible for the latter to be welded to the charger housing or else to be arranged and welded within the connection opening. In principle, however, other fastening means, for example a screw connection, soldered connection or adhesively bonded connection, are also conceivable. Further details, advantages and features of the present invention become apparent from the following description of an exemplary embodiment with reference to the drawing, in which:
  • Figure 1 shows an exemplary embodiment of an exhaust-gas turbocharger according to the invention
  • Figure 2 is a schematically simplified illustration of a coolant connection of the exhaust-gas turbocharger as per Figure 1, depicted on an enlarged scale, and
  • Figure 3 is a further illustration of a further exemplary embodiment of a coolant connection such as can be provided on an exhaust-gas turbocharger as per Figure 1.
  • FIG. 1 illustrates an exhaust-gas turbocharger 1 according to the invention in a schematically simplified illustration.
  • the exhaust-gas turbocharger 1 has charger housings, specifically a compressor housing 12 with compressor wheel 16 arranged therein, a bearing housing 11 with charger shaft 17 mounted therein, an actuator housing 40, and a turbine housing 13 with turbine wheel 15 arranged therein.
  • a device (not illustrated) for actuating a regulating element in the form of a wastegate 39.
  • the actuator 40 has a cooling jacket 43 by means of which heat generated in the actuator 40 itself, and externally supplied heat, can be dissipated to a coolant.
  • a cooling jacket 3 is likewise arranged in the bearing housing 11.
  • a cooling jacket of said type it is also possible for a cooling jacket of said type to be arranged in the compressor housing 12 and/or in the turbine housing 13.
  • the cooling circuit 43 of the actuator 40 may be connected to a low-pressure circuit.
  • the exhaust-gas turbocharger 1 furthermore has a coolant connection 4; 4' which has a connection flange 5 fastened to the charger housing (in the example illustrated, to the bearing housing 11 thereof).
  • connection flange 5 is, in the example, equipped with a feed pipe 6 for coolant and with a discharge pipe 7.
  • feed pipe 6 and discharge pipe 7 are integrated components which are connected to and extend through the connection flange 5.
  • connection opening 8 through which both the feed pipe 6 and the discharge pipe 7 extend, such that according to the invention, it is adequate for a single such connection opening 8 to be provided in the bearing housing 11 or actuator 40.
  • the feed pipe 6 is equipped with a bent pipe region 9 which engages into the charger housing or the cooling jacket 5.
  • a bent pipe region 9 of said type makes it possible for the coolant that is fed to have a preferred flow direction imparted to it.
  • the discharge pipe 7 to have an internal geometric formation for reducing flow resistance, which geometric formation makes it possible for the coolant to be discharged from the cooling jacket 3 of the bearing housing 11 or from the cooling jacket 43 of the actuator 40 in an expedient manner in terms of flow, said geometric formation being in the form of an inlet diffuser 10, for example.
  • a coolant connection 4' of alternative design is illustrated in Figure 3, said coolant connection having a single pipe 18 in which a feed line 6' and discharge line 7 may be formed. It can be seen that the pipe 18 has a bend in the interior of the bearing housing 11; 40 or actuator 40. An imaginary elongation of the feed line 7 ends at a housing section 19 which is formed as a means for diverting the coolant flow and which correspondingly diverts the coolant flow.
  • the housing section 19 may be a thermally highly loaded region of the exhaust-gas turbocharger 1.
  • the seal 14' illustrated in figure 3 is for example in the form of a flat seal (paper or FiNBR or NBR seal), though alternative seals are possible.
  • the coolant connection 4' with the elements described in this paragraph can be used, with the same effectiveness as the coolant connection 4 described in conjunction with Figure 2, for cooling the charger housing 11 ; 40 illustrated in Figure 1.
  • a seal 14; 14' is provided between the connection flange 5 and the charger housing 11; 40.
  • the seal 14 illustrated in Figure 2 is in the form of an O-ring.
  • the coolant connection 4, 4' is fixed to the bearing housing 11 or to the actuator 40 by means of a fixing element 50 which acts on the connection flange 5. It is self- evidently also possible for a welded connection (not illustrated) to be used for fixing purposes.
  • a welded connection (not illustrated) to be used for fixing purposes.
