  • the invention relates to a ventilation device of a motor vehicle according to the preamble of claim 1.
  • the ventilation device has several ventilation zones that can be temperature-controlled independently of one another.
  • the mixing rooms of the ventilation zones are separated from each other by a partition.
  • the partition extends up to an electrical auxiliary heater which is arranged in the exemplary embodiment shown between the heat exchanger and the partition.

  • the heating water heat exchanger has a heat exchanger grid with a depth, seen in the direction of flow, than the overall depth of the two heating water tanks of the heat exchanger.
  • the electrical auxiliary heater from the heat exchanger grid of the heating water heat exchanger can be installed, which results in an air gap due to assembly between the heat exchanger grid of the heating water heat exchanger and the downstream components and the air supplying the two mixing rooms of the ventilation zones separately.
  • the result of this is that, for example, when the hot air flaps are closed one zone and the resulting overflow of hot air from the heating water heat exchanger zone there via the air gap to the hot air flaps of the other zone, there is a mutual thermal influence and coupling of the two ventilation zones.
  • the object of the invention is to provide such a ventilation device, in particular equipped with a heat exchanger inserted transversely to the extension of the water tanks, which has improved thermal decoupling of the ventilation zones.
  • the partition wall can be designed in various ways on the heat exchanger. For example, it can be soldered to the heat exchanger grid, to the water tanks or to a heat exchanger tube.
  • edges of the sealing wall and partition are arranged in the housing of the ventilation device along an insertion direction of the heat exchanger. This ensures that the associated flat contours of the sealing wall and partition wall abut against one another or slide into one another during insertion of the heat exchanger and thus seal securely in position when inserted.
  • the sealing wall and partition form a tongue and groove connection, as a result of which there is a sealing overlap area in the region of the separating edge between the sealing wall and partition.
  • this results in an improved sealing effect and thus better thermal decoupling
  • a tongue and groove connection aligned along the insertion direction of the heat exchanger can engage in one another in a particularly good manner when inserted and can thus be brought into sealing engagement simply and securely.
  • the sealing wall is designed as a mounting part and can be attached to the heat exchanger.
  • standardized heat exchanger blocks can be adapted to different climate boxes by means of the installation of sealing walls with different designs.
  • An embodiment of the ventilation device in the heat exchanger grid in particular due to the missing or partially executed fins, has cutouts which are provided for receiving sealing wall holders.
  • the sealing wall holders reach for support on the opposite side of the heat exchanger tubes through the cutouts and thus encompass the heat exchanger tubes.
  • FIG. 1 is a partial sectional view of a ventilation device with a direction of view transverse to the heat exchanger tubes and transverse to the flow through the heat exchanger
  • Fig. 2 shows the section II-II of Figure 1 and
  • FIG. 3 shows the section III-III from FIG. 1.
  • Figure 1 is a section through a ventilation device 1 with a viewing direction along the elongated extension of an upper water tank 21 and a lower water tank 22 of a heating water heat exchanger 2 of the ventilation device and thus at right angles to the partition and sealing wall. Extending transversely to the water tanks 21 and 22 are the heat exchanger tubes 23, which connect them on the water side. Between two heat exchanger tubes 23, wave-shaped curved fins 24 are arranged across the sectional plane of the illustration.
  • the air to be heated flows through the heat exchanger 2 in the air-side flow direction A.
  • the section on which the illustration is based is arranged in the space between two heat exchanger tubes, a sealing wall 25 of the heat exchanger 2 being fastened to the heat exchanger tube lying in the viewing direction by means of holders 26 in the region of the upper water container 21 and holders 27 in the region of the lower water container 22.
  • the housing 11 of the ventilation device 1 has an opening on its upper side in the installed position, through which the heat exchanger 2 is pushed into the housing in the insertion direction X.
  • a formally corresponding recess is provided for the sealing wall 25 of the heat exchanger 2 in the top of the housing 11, through which the sealing wall 25 together with the in the insertion direction X.
  • Heat exchanger 2 can be inserted.
  • the cutout of the upper side of the housing 11 of the ventilation device 1 provided for the sealing wall 25 forms a bay-shaped extension of the insertion opening of the heat exchanger 2.
  • the cutout is sealed off by the sealing wall 25 inserted with the heat exchanger 2.
  • the area of the insertion opening in the housing 11 which is penetrated by the local water container 21 is sealed by this. Additional sealing elements, such as foam seals, can be provided for this.
  • the insertion direction of the heat exchanger X can, as in the present exemplary embodiment, take place transversely to the elongated extension of the water tanks 21 and 22, that is to say along the elongated extension of the heat exchanger tubes 23, or also along the elongated extension of the water containers 21 and 22 and thus transverse to the elongated extension of the heat exchanger tubes 23.
  • the sealing wall 25 of the heat exchanger 2 can be aligned along or transversely to the direction of insertion X of the heat exchanger. If the sealing wall is aligned transversely to the direction of insertion, it is pushed towards the partition wall and comes to the partition wall in the sealing position in the inserted position of the heat exchanger.
  • the sealing wall 25 can thus depend on the mutual alignment of the elongated extension of the water tank and the direction of insertion relative to one another and the elongated extension of the sealing wall and the insertion direction relative to one another or be arranged transversely to the elongate extent of the water tanks 21 and 22 on the heat exchanger grid.
  • the inserted partition wall 25 engages around a central partition wall 13 of the housing of the ventilation device 1 with a groove shape not shown in the illustration in FIG. 1.

  • FIG. 2 shows a section along the line II-II of Figure 1.
  • the sealing wall 25 of the heat exchanger 2 has a groove-shaped receptacle 28 for the central partition wall 13 of the housing of the ventilation device.
  • the sealing wall 25 is fastened to a heat exchanger tube 23 by means of a holder 27, the holder 27 encompassing two clamp arms which engage behind on the side of the heat exchanger tube 23 facing away from the sealing wall 25.

  • the feed-through openings 29 form recesses for the holder 27 of the sealing wall 25 there.
  • the sealing wall 25 lies with one edge directly on the heat exchanger tube 23 and thus forms a sealed separation of the air heated by the heat exchanger into two separate warm air zones.
  • the sealing wall 25, which is brought up to the heat exchanger tube 23, is in contact with the water tanks of the heat exchanger 2 in the area of the joining surfaces of the heat exchanger tubes in the water tanks 21 and 22 and is supported in this way on the water tanks 21 and 22 of the heat exchanger.
  • the forces that occur during insertion along the sealing wall for example due to friction of the center partition 13 in the groove-shaped receptacle 28, are essentially passed on to the base body of the heat exchanger 2 in a dimensionally stable manner through these contact points of the sealing wall 25 on the water tanks 21 and 22.
