Definitions

  • the invention relates to a dryer-filter insert for a collector of a capacitor according to the preamble of claim 1 - known by the DE 199 12 381 A1 the applicant. Furthermore, the invention relates to a capacitor according to the preamble of claim 11.
  • a dryer cartridge is arranged, which extracts moisture from the refrigerant Similar arrangements with lower subcooling line and associated filter-dryer cartridge were arranged by the FR 2 750 761 A1 as well as the EP 1 132 695 A1 known.
  • the condenser on a collector which can be equipped with an insert, consisting of a riser, a partition wall and optionally from a dryer-filter element.
  • the condenser has a condensation section underneath the upper subcooling section, which is flowed through in multiple flows from bottom to top. Thereafter, the largely liquefied refrigerant passes through an overflow into the collector, flows through the dryer-filter element and passes through the riser in an overhead sealed by the partition chamber, which is in communication with the subcooling via a further overflow in refrigerant connection
  • DE 1 0250 384 also discloses a dryer-filter insert according to the preamble of claim 1.
  • the riser is designed as a support element and carries both the partition between the subcooling and condensation section and the dryer-filter unit.
  • the riser is designed as a support element and carries both the partition between the subcooling and condensation section and the dryer-filter unit.
  • the partition is designed as a separating plug, d. H. a disc of aluminum or plastic, which preferably carries on its periphery one or more sealing rings. This results in a secure seal between the uppermost chamber of the collector, which is in communication with the lower cooling section, and the underlying chamber, which is in communication with the condensation section.
  • the dryer-filter unit is designed as a known plastic cage, softer with a dryer material in the form of granules can be filled.
  • a relatively large peripheral surface is created for the entry of the refrigerant, whereby an effective drying of the refrigerant is achieved.
  • the plastic cage in its lower region on a circumferential sealing lip, which seals an annular gap between the cage and the inner wall of the collector.
  • the plastic cage is pushed onto the riser and held there in a positive fit.
  • both parts can be easily joined and positioned to each other.
  • a perforated sleeve which communicates on the one hand with the lower riser and on the other hand with the subcooling.
  • a sealing plug is attached to the perforated bush, which forms the conclusion of the dryer-Filtet insert according to the invention upwards.
  • the upwardly open collector of the capacitor can thus be closed and sealed by mounting the insert according to the invention by the sealing plug, wherein a fuse in the axial direction by a locking ring can.
  • the insert is therefore also exchangeable, ie it can be removed for repair or maintenance purposes.
  • the bushing forms the connecting piece between separating plug and sealing plug, which at the same time causes the positioning of the riser pipe and of the dryer attached to the riser pipe.
  • the object of the invention is also solved by the features of claim 11, by a capacitor with overhead subcooling with the inventively constructed dryer-filter insert is equipped.
  • the advantage here is that the dryer-filter insert is easy, quick and safe to install and exchangeable.
  • Fig. 1 shows a dryer filter insert 1 for use in a Fig. 3 illustrated collector of a condenser for a motor vehicle air conditioning.
  • the dryer-filter insert 1 consists of a riser 2, a plastic cage 3, a separating stopper 4, a perforated sleeve 5 and a sealing plug 6. All parts are joined into a unit.
  • the riser 2 may be formed as a plastic tube and frictionally carries the known plastic cage 3, which is filled with a dryer material in the form of granules in the lower part of the plastic cage 3 is a circumferential, preferably molded sealing lip 7 is arranged, the plastic cage 3 against the here not shown inner wall of the collector seals.
  • the refrigerant is forced to flow through the plastic cage 3 inside and thus to contact the dryer material.
  • a sealing ring 8 At the upper end of the riser pipe 2 formed as a disc separating stopper 4 is fixed, which on its circumference a sealing ring 8, z. B. carries an O-ring.
  • the socket 5 is perforated, so that the through the riser 2 rising refrigerant from the socket 5 can escape to the outside, ie in the subcooling section, not shown here.
  • the sealing plug 6 is fixed, which also carries on its circumference at least one sealing ring 9, which may be inserted into an annular groove, not shown.
  • the bushing 5 is preferably made of plastic, while the sealing plug 6 for reasons of strength preferably consists of an aluminum alloy - as well as the collector.
  • Fig. 2 shows the dryer-filter insert 1 in a side view, it being understood that the riser pipe 2 penetrates the plastic cage 3 inside and protrudes with a lower end 2a above the bottom of the plastic cage 3.
  • the bushing 5 acts as a connecting piece between separating stopper 4 and sealing plug 6, is inserted into the two plugs at the front end and fastened there
  • Fig. 3 shows a condenser 10 with an overhead subcool 11 and a condensation section 12 arranged underneath, which, as shown by arrows, is flowed through in three columns from bottom to top.
  • the condenser 10 has two lateral collecting pipes 13, 14 and a collector 15 arranged parallel to the collecting pipe 14, which is connected to the collecting pipe 14 via two overflow openings 16, 17.
  • Such a capacitor 10 is known from the above DE 199 12 381 A1 the applicant known, in particular, as regards its function. The content of this disclosure of the applicant is therefore fully incorporated in the disclosure of the present application.
  • the above-described dryer-filter insert 1 is used, wherein the sealing plug 6 is fixed in the axial direction relative to the collector 15.
  • the lowest end 2a of the riser 2 is located slightly above the bottom of the collector 15, so that refrigerant can be sucked.
  • the separating plug 4 is located between the overflow openings 16, 17, so that a seal between the upper subcooling 11 and the underlying condensation section 12 and the communicating chamber of Collector 15 is administratgestallt.
  • the circumferential sealing lip 7 is arranged, which rests against the inner wall of the collector 15 and thus forces the refrigerant to flow through the plastic cage 3 inside. Below the sealing lip 7 thus collects the dried refrigerant, which is sucked in via the suction port 2 a of the riser 2 and conveyed upwards into the bushing 5, from where it enters the subcooling 11.
