Definitions

  • the invention relates to a refrigerant condenser with a network consisting of tubes and fins, manifolds arranged on both sides of the network and with at least one inflow and at least one outflow opening connected to one of the manifolds and arranged parallel to the manifold, in particular according to the preamble of claim 1 or of claim 10.
  • the invention also relates to an insert for a collector of a condenser of an air conditioning system for motor vehicles, in particular according to the preamble of patent claim 13.
  • the capacitor known from DE-A 197 12 714 by the applicant is a so-called capacitor module, which is characterized by a collector integrated with the capacitor.
  • This collector is tubular, is arranged parallel to one of the two collector pipes of the condenser and is in fluid communication with the adjacent collector pipe via an inflow opening and an outflow opening.
  • a dryer / filter cartridge is positioned in the collector, which is positively and releasably connected to a sealing plug via a snap-in connection. The dryer / filter cartridge is removed after soldering the
  • the dryer / filter cartridge has a plastic housing with a circumferential sealing lip which is arranged between the inflow and outflow openings and divides the collector into an inflow space and an outflow space. After flowing through the dryer / filter cartridge, the refrigerant then flows from the inflow space into the outflow space and thus back into the condenser network.
  • a detailed description of such a capacitor module can be found in DE-A 44 02 927 by the applicant.
  • dryer / filter cartridges were known from DE 200 04 438 U1, FR-A 2 750 761 and EP-A 0 921 022.
  • the DE '438 requires spacers to position the dryer / filter cartridge in the collector.
  • the dryer / filter cartridge according to EP '022 and FR 761 requires a partition in the collector into which the lower end of the dryer / filter cartridge is inserted, while the upper end is connected to the sealing plug.
  • a disadvantage of these designs is that the cartridge is relatively long and is not easy to handle with regard to installation and removal.
  • the solution to this problem results from the features of independent claim 1.
  • the spatial separation of drying and filtering of the refrigerant results in a lower pressure drop for the refrigerant that flows through the collector. This reduced pressure drop has a positive effect on the performance of the entire condenser.
  • the drying / filtering functional unit is simplified in its structure because additional individual parts such. B. spacers are omitted.
  • the length of the entire insert is shortened by the arrangement of the sealing plug and the insert connected to it in the lower region of the collector, that is to say in the region of the inflow and outflow opening.
  • the insert is cup-shaped and constructed as a separate filter unit, which is either clipped with the sealing plug as an assembly unit or is formed in one piece as an injection molded part.
  • the filter effect is functionally improved in so far as the refrigerant first flows into the interior of the cup-shaped insert, from there radially outwards via filter screens into an annular space and from there back into the condenser.
  • Filter screens on the circumference result in a larger filter passage area and thus a lower pressure drop for the refrigerant. Dirt particles that are retained by the sieve can collect on the bottom of the pot-shaped insert and therefore do not clog the filter.
  • the production costs can be reduced by producing the insert and sealing plug as a one-piece molded part, be it from plastic or from an aluminum alloy.
  • the insert is positioned in the collector at the same time, which is particularly important for the sealing lip, since this must be arranged between the inflow and outflow opening.
  • drying is carried out by means of a dryer bag positioned above the filter insert, which is refrigerant-permeable and accommodates a dryer assembly in its interior. This small bag is supported on the edge of the cup-shaped insert, so that the cavity inside the filter insert remains free.
  • the filter insert is extended as a one-piece plastic injection-molded part to form a dryer cartridge which receives the dryer granulate. It is thus possible to insert the dryer and filter as one part with the sealing plug from below into the collector and to position it there in its operating position.
  • the top of the dryer cartridge i. H. Above the sealing lip has a relatively large circumferential surface, which is pierced by windows and covered by a relatively coarse-mesh filter fabric. This will keep larger dirt particles outside the cartridge.
  • the lower part of the cartridge, i.e. H. below the sealing lip also has window-like openings, which, however, are covered by a relatively close-meshed filter screen. The combination of a coarse and fine mesh filter reduces the pressure drop in the cartridge.
