Definitions

  • the invention relates to a capacitor, in particular for a motor vehicle air conditioning system according to the preamble of claim 1 - known from DE-A 103 06 192.
  • the known from DE-A 103 06 192 capacitor has a collector arranged parallel to a collector, in which a filter and / or dryer cartridge is arranged and positioned by an annular retaining rib in the axial direction in the collector.
  • the retaining rib is elastically deformable and held in an annular groove of the collector so that the retaining rib and the annular groove form a snap or latching connection. It can not be ruled out that the known locking connection dissolves during assembly or during operation of the capacitor, so that the dryer and / or filter cartridge is no longer fixed in the collector and can not perform their function. The operation of the air conditioner can be affected.
  • the known collector has a releasable closure part, so that the dryer and / or filter cartridge after soldering of the capacitor mountable and interchangeable during operation for maintenance reasons.
  • the closure member is preferably formed as an axially movable sealing plug, which is fixed by a retaining ring in an axial direction (outward). Such a sealing plug was known from DE-A 100 39 260.
  • the stop is formed as an annular disc which is fixed axially relative to the collector, preferably by a non-positive or positive connection, in particular by caulking.
  • the disc advantageously has passage openings on its circumference and does not form a substantially increased flow resistance for the refrigerant.
  • the dryer-filter cartridge can thus be supported with its end face relative to the disk, wherein an axial gap is left as a game, which corresponds to the mobility of the dryer-filter cartridge, due to the primary positioning means, preferably a latching connection.
  • the dryer cartridge thus only supports against the stop or the disc if the primary positioning means fail, ie. H. the retaining rib emerges from the associated annular groove. In the other direction, the dryer-filter cartridge is secured by the closure part.
  • the stopper is formed integrally with the collector, for example by non-cutting forming or cutting machining produced.
  • the collector is - as known per se - made of a profile piece and a tube, wherein the one-piece stop is arranged in the profile piece, advantageously as an inwardly projecting annular rib on which the sealing lip of the dryer-filter cartridge is supported.
  • the annular stop can be incorporated into the bore of the profile piece without significant additional effort.
  • between the sealing lip and the annular rib is an axial gap provided so that a support occurs only in case of failure of the primary holding means.
  • the one-piece solution and a two-piece solution is possible, for. B. such that a retaining ring is inserted into an annular groove - similar to the sealing plug.
  • Fig. 1 shows a collector 1 partially shown in longitudinal section and as a 3-D representation, wherein the collector 1 is composed of a tube 2 and a profile piece 3.
  • the profile piece 3 preferably produced by extrusion, has an upper end opening 3a and is closed by a sealing plug, not shown, which is known, for example, from DE-A 100 39 260 of the Applicant mentioned above.
  • a filter-dryer cartridge 4 is arranged, which is preferably designed as a plastic cage and accommodates a dryer material, not shown.
  • the plastic cage has - as known from the aforementioned DE-A 103 06 192 of the Applicant - a retaining rib 5 and a sealing lip 6, wherein the retaining rib 5 is held in an annular groove of the profile piece 3, not shown.
  • Retaining rib 5 and annular groove form a latching connection and are referred to as primary holding or positioning means which fix the dryer-filter cartridge 4 in its axial position in the collector 1.
  • the collector 1 and the dryer-filter cartridge 4 are parts of a capacitor, as described for example in DE 103 06 192 A1 - the subject of this patent application of the Applicant is therefore incorporated in the disclosure of the present Registration included.
  • the dryer-filter cartridge 4 has a (in the drawing) upper end-side end 4a, which is supported against the closure part, not shown, and a (in the drawing) lower Stimende 4b, which is supported against a pipe 2 fixed to the ring disc 7 , which is shown enlarged as a detail X n Fig. 2.
  • Fig. 2 shows the annular disc 7 as a detail in an enlarged view, which rests with its outer periphery on the inner wall of the tube 2 and is caulked against the tube 2, ie by non-cutting deformation of the tube 2, z. B. radially directed impressions is fixed in the axial direction. The pressure points or caulking are conical and occupied by the reference numbers 8.
  • the annular disc 7 has distributed over the circumference through openings 9 in order to minimize the flow resistance and the weight.
  • the annular disc 7 forms a stop for the front end 4b of the dryer-filter cartridge 4, wherein between the end face 4b and the end face of the annular disc 7, an axial gap is left as a game.
  • the stop 7 becomes effective only when the primary holding means 5 (see Fig. 1) fail. In this case, the axial path of the dryer-filter cartridge 4 is blocked by the annular stop 7. The function of the dryer-filter cartridge 4 is thus secured in the event of failure of the primary holding means 5.
  • Fig. 3 shows a further embodiment of the invention for a collector 10, which has a profile piece 11 and an only incomplete and dashed tube 12 shown.
  • a dryer-filter cartridge 13 is arranged, which is designed as a plastic cage and filled with not shown dryer material.
  • the profile piece 11 has an upper end opening 11a, which is releasably closed with a closure plug 14, shown by a dashed line.
  • the profile piece 11 has two pairs 15, 16 of overflow openings, which produce a connection to a collecting pipe, not shown here, of the capacitor, as known from the aforementioned prior art.
  • the dryer-filter cartridge 13 is by primary holding or positioning means in the form of a retaining rib 17 and an annular groove 18 in the profile piece 11th fixed in the collector 10 in the axial direction, resulting in a certain axial play due to the elasticity of the retaining rib 17 and the width of the annular groove 18.
  • a circumferential sealing lip 19 is arranged, which is preferably integrally molded with the plastic cage 13, as well as the retaining rib 17.
  • a ring-shaped stop 20 is arranged, which preferably integrally with the Collector 11 is formed, for. B. made by cutting deformation of the material of the profile piece 11.
  • Fig. 4 shows the embodiment according to FIG. 3 as a 3-D representation, and wherein the profile piece is shown with a shell-shaped projection 21 11 which accommodates an unillustrated here manifold in a known manner, which is connected to unillustrated flat tubes of the condenser block ,
  • the illustration shows that the overflow openings 15, 16 connect collector and manifold together.
  • the annular rib 20, which serves as a stop for the dryer-filter cartridge 13 is shown hatched for clarity. Above are the sealing lip 19 and the retaining rib 17th
