Definitions

  • the invention relates to a condenser for an air conditioner, in particular a motor vehicle according to the preamble of patent claim 1.
  • Condensers for vehicle air conditioners consist mostly of aluminum materials and are therefore brazed in a soldering process.
  • the capacitor has an integrated collector, d. H. a tubular collecting container, which is arranged parallel to one of the two manifolds of the capacitor and connected to the manifold manifold side.
  • a dryer cartridge d. h a container or cage in which a dryer material, in particular in the form of a dryer granules is arranged. The granules extract moisture from the refrigerant.
  • the dryer cartridge is - due to the design - used after soldering the capacitor in the open collector and positioned there. Subsequently, the collector, z. B. closed by a screw cap. Thus, the dryer cartridge is also interchangeable later, z. B. for maintenance purposes.
  • the dryer is soldered simultaneously with the capacitor and the collector.
  • the dryer granulate is made of a heat-resistant material, which survives the temperatures occurring during the soldering process without damage.
  • solderable or mitlötbaren dryers This is referred to as so-called solderable or mitlötbaren dryers, which have the advantage that the subsequent installation of the dryer cartridge and the closing of the collector omitted.
  • a problem in the production of solderable dryers is that the dryer granules absorb moisture from the environment in the period between the filling of the granules into the collector and the beginning of the soldering process. During the soldering process, the moisture enters the soldering atmosphere as water vapor, which impairs the quality of the soldering process. It has therefore been proposed in JP-A 2001-141332 to heat (preheat) the dryer material immediately before the soldering process, so that the moisture escapes before the dryer material reaches the soldering atmosphere. The disadvantage of this solution is that an additional step before the soldering process is necessary.
  • a capacitor of the type mentioned, d. H. to provide with solderable dryer, in which eliminates the disturbing influences of moisture contained in the dryer material or at least significantly reduced. It is another object of the invention to provide a corresponding method, according to which a soldering process can be carried out without Moisture effect.
  • the dryer material after the deposit in the collector to the atmosphere is lockable, this being done advantageously by a temperature-sensitive closure means.
  • this may be a paint which is sprayed on a screen of the dryer and thus closes the openings of the screen, or a plastic film which closes an end face of the collector.
  • the temperature-sensitive sealing means in the form of paint, PU binder or film dissolve without residue under the action of temperature of the soldering process, at least without harmful residues. It would also be possible, for example, to include the dryer granules in a film-like shell before filling into the collector, which also dissolves under the effect of the soldering temperature. After the soldering process, the refrigerant then - during operation of the condenser - the required access to the dryer granules.
  • the object of the invention is also achieved by a method wherein the dryer material is sealed immediately after filling with respect to the atmosphere. During the subsequent soldering process, the seal due to heat wine effect is eliminated, so that the refrigerant of the refrigerant circuit has access to the dryer granules. The quality of the soldering is thus improved.
  • Fig. 1 shows a tube 1 of a not fully shown collector for a capacitor.
  • the latter corresponds in its structure known capacitors, as shown and described in the aforementioned prior art, ie DE 102 13 194 A1 and DE 103 38 526 A1 of the applicant. The content of these two applications is fully incorporated in the disclosure of this application.
  • the tube 1 shown in Fig. 1 which has a lower open tube end 2, connected to a preferably extruded, not shown pipe section, which completes the collector.
  • the latter is in a known manner with a manifold, not shown, of the capacitor mechanically and cold side connected via overflow openings, not shown.
  • the refrigerant via the lower tube end 2 access to the interior of the tube 1.
  • the latter further comprises an upper tube end 3, which is closed by a cover 4 having a holding arm 4a for attachment to the adjacent manifold, not shown.
  • the upper portion of the tube 1 is formed as a chamber 5, which is bounded below by a sieve 6.
  • the sieve 6 is fixed with its circumference to the inside of the tube 1, for example, by beads 7 in the tube 1.
  • the chamber 5 is filled with a dryer granules 8, which has the task to extract moisture from the refrigerant.
  • the aforementioned parts 1 to 8 form an assembly, which is referred to as a dryer unit 9.
  • the thus pre-assembled dryer unit 9 is completed with the rest of the capacitor and soldered. So that the dryer granules 8 does not absorb moisture from the environment in the period between pre-assembly of the dryer unit 9 and the transfer to a brazing furnace, this must be done as quickly as possible. Nevertheless, a moisture absorption can not be excluded.
  • the invention begins by the chamber 5 with the dryer granules 8 to the outside, d. H. in the direction of the lower tube end 2 gas or moisture-tight is completed. This is done according to the invention by a seal or coating of the screen 6 with a suitable paint, which closes the openings of the screen 6. This is shown in greater detail in FIG. 3 and will be described in connection with FIG. 2.
  • Fig. 2 shows a second embodiment of the invention, shown on the same tube 1 for the same dryer unit 9.
  • the lower tube end 2 by a film 10, preferably made of plastic moisture-tight (the sieve 6 is not sealed here).
  • Fig. 3 shows two sections A (before soldering) and B (after soldering) of the screen 6 in Fig. 1.
  • the screen fabric with a polyurethane binder (PU) is sealed, ie the meshes are characterized by a thin Closed layer of PU binder and thus form a moisture seal.
  • the pre-assembled dryer unit 9 for mounting with provided with the condenser and the soldering process moisture can not penetrate from the environment into the interior of the granule-filled chamber.
  • the lower section B shows the screen fabric after the soldering process, d. H.
  • the capacitor has been soldered with collector and dryer in a Lötatmospotrore at soldering temperatures of about 580 ° Celsius.
  • the polyurethane binder dissolves or evaporates. This is harmless for the soldering atmosphere or the soldering process.
  • the sieve is fully functional again, d. H. the refrigerant of the refrigeration cycle has access to the dryer granulate through the sieve, which can thus fulfill its task of drying.
  • the dryer granules remain "dry" during the waiting time before the soldering process, ie. H. it can not absorb moisture from outside.
  • the dryer unit 9 with film 10 is completed with the extruded end of the collector and the rest of the capacitor and spent in the Lötatmospotrore. In this case, the film 10 melts. Moisture can not get into the soldering atmosphere, since no moisture was contained in the granules during the soldering process. After soldering, the refrigerant has access to the dryer granules due to dissolution of the film.
