Definitions

  • the invention relates to a heat exchanger, in particular a cooling liquid cooler for a motor vehicle, having two collection boxes arranged on opposite sides with longitudinal and end walls and having a multiplicity of openings each receiving a tube through which a medium flows, with an inlet and an outlet , And with a partition wall in the collecting box, in which there is a breakthrough, which can be closed by means of a drain member, and with a closable opening in a wall of the collecting tank.
  • the heat exchanger is asdestattkeitkühler from the EP 818 663 B1 known.
  • a partition is arranged in one of the collecting boxes, the opening of which is closable with a sealing plug.
  • the cooler can be formed with or without low temperature range. It is in the EP 818 663 B1 always just a single cooling circuit, which is passed through thedeckenkeitkühler.
  • the known solution can not be adopted, ie for the emptying of the circuits would have independent organs, possibly even in several heat exchangers, are used, which requires appropriate effort.
  • the object of the invention is to heat exchanger, in particular for a motor vehicle, in such a way that the emptying is further simplified.
  • a second partition wall approximately at the same height, is arranged in the other collection box, wherein the first and the second partition wall separates two cooling circuits from each other and in that the discharge member is designed so that the contents of both circuits can be emptied with a discharge member, the emptying of both circuits was achieved and simplified.
  • Fig. 1 shows a view of a cooling module of a motor vehicle.
  • 2 shows schematically the lower part of the cooling liquid cooler present in the cooling module in one first embodiment.
  • Fig. 3 shows in a section a second embodiment.
  • the cooling module comprises several heat exchangers, all of which are in the form of aluminum as all-metal heat exchangers and which can therefore be recycled without expensive material separation.
  • a cooling liquid cooler 1 and above a charge air cooler 20.
  • the cooling air flows through the cooling module, which is usually arranged in the front region of the motor vehicle.
  • a condenser for the air conditioning system and, if required, further heat exchangers, for example oil coolers, which are not clearly visible in FIG.
  • the left header 3 of the cooling liquid cooler 1 has an inlet 5 for the cooling liquid and the right header 2 a corresponding outlet 6.
  • the inlet 5 and the outlet 6 are in an embodiment not shown on one and the same collecting box, which belongs to the prior art and therefore should be included in the preamble of claim 1.
  • the described embodiment forms part of a first circuit not otherwise shown.
  • Another separate circuit is present, which is also not shown further.
  • the cooling liquid enters the lower part of the cooling liquid cooler 1 via the inlet 50 at the right collecting box 2 and leaves this lower part via the outlet 60 at the left collecting box 3. Since both circuits (not shown further) are independent of one another, the direction of flow is optional. It was indicated by arrows for this embodiment.
  • the cooling liquid flowing through the lower part of the cooling liquid cooler 1 leaves the same at a lower temperature, therefore, there is noted "low-temperature flow”.
  • main flow is noted, which expresses that the local first circuit has a much larger mass flow. Above all, it serves to cool the engine.
  • Fig. 2 shows now the lower part of thedeckenkeitskühlers 1 a little closer, with details have been omitted.
  • the coolant radiator 1 is known to have one or more rows of flat tubes 4. Located between the flat tubes 4 corrugated fins 15 or the like, through which the cooling air flows. The lower part of the coolant radiator 1 is bounded by a side part 40 which connects the two header tanks 2, 3 . Side parts 40, flat tubes 4, corrugated fins 15 and
  • Collector boxes 2, 3 are, like the other heat exchangers of the cooling module, designed as a solder joint, so that an intimate contact is present, which allows efficient heat exchange between cooling air and coolant.
  • the mentioned two circuits are separated by a partition 10 in the left header 2 and another partition 14 in the right header 3 . This should be indicated by means of the flow arrows with solid (above) or dashed lines (below).
  • the discharge member 12 closes in this position at the same time the opening 13 in the wall of the collecting tank 2. It can be seen from the illustration that after removal of the drain member 12, the contents of both circuits can be emptied, since the hydraulic separation between the circuits canceled and the discharge opening 13 is no longer closed.
  • Fig. 3 shows an alternative to the embodiment described above, wherein only a section is shown, showing the design of the discharge member 12 and its interaction in the immediate region thereof.
  • the rest is identical to FIG. 2.
  • the drain member 12 is formed in two parts. It has a sealing plug 17, which sits in the opening 13 of the wall of the collecting tank 2 .
  • the closure plug 17 has a pin 9 which blocks the passage opening 7 in the second part of the discharge member 12, for example in a pipe piece 8 . After removal of the sealing plug 17 from the opening 13 also both circuits can be emptied, the liquid flows from the upper circuit through the passage opening 7 and on to the opening 13 and the liquid from the lower circuit will flow directly through the opening 13 .
  • the pipe section 8 can remain in its position.
