Definitions

  • the invention relates to a water / air heat exchanger made of aluminum or an aluminum alloy for motor vehicles, in particular on a heating heat exchanger or engine cooler, according to the preamble of claim 1.
  • the characteristics of the generic term are from DE-A-34 40 489 in a radiator of a motor vehicle known per se in a double flow arrangement.
  • the Features of the first paragraph of the characterizing part are also in the unpublished older European patent application Applicant's EP-A-632 245.
  • the engine cooler has one Plastic cover on an elastic molded seal tightly connected to an otherwise metallic radiator block becomes.
  • the tube plate of the water box faces outwards collar up.
  • the inserted in slots in the tube sheet Flat tubes end flush with the flat surface of the Tube sheet facing the interior of the water tank is.
  • the partition in the water tank is also over the elastic molded seal against which the two floods from each other separating partitions sealed in the flat tubes.
  • the alloys in particular come within the scope of the invention AlMnl or AlMgSi or A199.5 in question, the two former alloys preferably for pipes, water boxes and plates and the latter alloy are preferred can be used for zigzag slats.
  • Pipes and Water boxes are expediently braided on both sides with AlSi7 pre-coated.
  • This solder coating is made after assembly with flux, e.g. a sodium fluoride and potassium aluminum fluoride sprayed. The soldering to the final product after the invention is protected, then takes place in a soldering furnace under protective gas without adding further solder to the precoating.
  • Water / air heat exchangers such as engine coolers or in particular Heating heat exchanger on which the invention specifically related are also heat exchangers, which are in contrast for example to evaporators or condensers in a cooling circuit be arranged within a motor vehicle.
  • a cooling circuit is used as an internal heat exchange medium Water or water with an anti-freeze additive such as Glycol.
  • the ambient air serves as the external heat exchange medium.
  • Such water / air heat exchangers for motor vehicles are thus operated at a relatively low internal pressure, and at an operating pressure of about 1.5 to a maximum of 2 bar and an inlet pressure of 4 bar in particular.
  • Evaporator and condensers of air conditioning systems in motor vehicles on the other hand, a non-water-based coolant, e.g.
  • the water / air heat exchangers, to which the invention relates operated in cross-countercurrent.
  • Required for such countercurrent operation one at least double-flow heat exchanger.
  • DE-A-34 40 489 is for the manufacture of a cooler from Manufactured from aluminum or a motor vehicle Aluminum alloy not disclosed.
  • the invention is the general task based on a heat exchanger in the preamble of claim 1 designated type both in terms of cost and function to optimize with minimal use of materials.
  • the invention is concerned with the task, the tightness of a solder joint between different To further improve areas of the heat exchanger, paying particular attention to the tightness between the upstream and downstream departments of the Water box and in its connection area to the flat tubes is placed.
  • the tube sheet of the water tank is like this built as thin as possible. Build yourself during manufacturing thereby tension in the tube sheet, which during its manufacture Made of light metal, especially aluminum and the alloys AlMnl or AlMgSi or A199.5, during the soldering process loses tension again but becomes wavy. This makes it difficult to separate the partition in the water tank tight with the tube sheet under tight communication to be soldered to the openings of the individual flat tubes.
  • a corresponding one that promotes tolerance compensation Connection of the partition in the water tank with its Lid shows claim 6 in the event that partition and cover consist of separate components.

  • the rejuvenation the tongues on the partition also an insertion assembly aid represents.
  • Claim 3 takes into account the fact that a optimal soldering of the partition to the collar under immediate These elements are soldered and not under Interposition of wall elements of the free ends of the Flat tubes.
  • the slot-like design of the respective cutout in the flat tube is dimensioned accordingly, so that both the Cutouts in the flat tube as well as the cutouts on the collar are dimensioned so that they are just the partition of the water tank can include.
  • the reason of the cutouts in the collar as well as the free end face of the respective partition in the flat tube no longer need to be adapted to each other level-wise to be, so that in particular such tolerances are compensated can be caused by warping of the tube sheet come from.
  • the slit-like cutout on the respective flat tube prevents by its dimensioning that the Tightness in the collar area is not due to leakage in the area the common level of the partition of the water tank on the one hand and the level through the partitions of the flat tubes on the other hand is rendered ineffective.

Even so, the lid can collapse of the water box counteracted during the soldering process become.
  • the end plate each has a receiving groove for the respective free open end of a flat tube. In the preparation of these grooves in the end plate are very demanding the deformability of the metal sheet, which is used for the end plate, which either not allow a large groove depth, which leads to insecure seat of the Can lead flat tubes, or with sufficient groove depth There is a risk of the metal tearing.
