Definitions

  • Such a filter dryer cartridge is in the EP 1 147 930 A1.
  • the filter cage just a single set of window openings that are all at the same axial height.
  • the sieves everyone who covers these window openings can radial over their entire area in the same way are blown by the refrigerant. It has in the Practice has shown that these screens are proportionate quickly clog with dirt, so that after relatively exchanged the filter dryer cartridge for a short time or needs to be cleaned.
  • the object of the present invention is a filter dryer cartridge of the type mentioned at the beginning that their service life is longer.
  • the filter holder provided according to the invention also provides the one at the bottom of the filter cage is already in place the existing annular shell for a Kind of "dirt trap" in which entrained by the refrigerant Dirt particles, for example abrasion from the desiccant, retained and collected for a long time can be without the flow through the filter cage to hinder.
  • Dirt trap entrained by the refrigerant Dirt particles, for example abrasion from the desiccant, retained and collected for a long time can be without the flow through the filter cage to hinder.
  • These dirt particles can namely the relatively coarse-mesh sieve of the portafilter from Step down through the top, vibrating and Shocks that the entire capacitor in operation exposed, promotes the passage of dirt particles.
  • the return of the dirt particles from the bottom up that is not supported by such vibrations on the other hand with a much lower probability, so that the sieve of the portafilter is similar in a sense a check valve acts.
  • the filter cage is a set of first window openings arranged at the same axial height and a sentence from below in another axially height arranged further window openings having.
  • the flow cross-section for the refrigerant becomes very large in this way, so that the throttling losses stay small.
  • the sieve surfaces of the filter cage and / or the portafilter can either consist of sieve mesh or through Perforations in the filter cage and / or the filter holder be educated.
  • the portafilter on its Provide a radially outer edge with a sealing lip is.
  • This sealing lip lies in the assembly position the filter dryer cartridge on the inner surface of the collector housing and ensures that the refrigerant actually on its way down flow through the sieves carried by the portafilter got to.
  • FIG. 1 with the reference numeral 1 is the housing Called collector, which is part of a capacitor, as described in EP 1 147 930 A1 mentioned above is. Attached to the housing 1 is to be thought of a tube-fin block, through which refrigerant flows becomes. Partly in the liquid phase, partly refrigerant present in the gaseous phase the upper area of the tube-fin block and enters via an inlet opening 2 into the interior of the housing 1 of the collector, flows through it in the following to be described and passes through an outlet opening 3 out of the housing 1 of the collector and into one lower section of the tube-rib block.
  • the filter dryer cartridge 4 comprises a cylindrical, tubular desiccant housing 5 that with a variety radial through openings 6 is provided.
  • a Bed 7 of desiccant the grain of which is so large that the individual desiccant particles the through openings 6 do not pass through the desiccant housing 5 can.
  • the desiccant housing 5 is at its lower edge, which has projections 8 projecting radially inwards for this purpose, in a circumferential groove 9 with a total of Reference number 10 provided elastic filter cage locked.
  • the filter cage 10 has the shape of a pot upside down, i.e. open to the bottom. It has a first set of large window openings 11, made of screen material 12 are covered. Axially below the first sentence of window openings 11 is a second set of window openings 13 provided, also with screen material 14 are covered.
  • axially parallel Web 15 which are also at the same axial height Window openings 13 through axially parallel webs 16 from each other separated while those in different axial Elevated window openings 11 on the one hand and 13 on the other hand by a circumferential Web 17 are separated from each other.
  • a ring shell 18 extending radially outwards is formed, in its radially outermost area into one Sealing lip 19 runs out.
  • the sealing lip 19 is elastic resilient on the inner surface of the housing 1 of the Collector.
  • the upper window openings 11 of the separates lower window openings 13 is in the outer
  • a groove 20 is formed in the outer surface of the filter cage 10.
  • this groove 20 is an annular, downward conically expanding filter holder 21 is used. This has in its conical surface, as in particular 4 shows four ring segment-shaped Openings 22, 23, 24, 25, each with a coarse mesh Screen material 26 are covered.
  • the lower, radially outer edge of the filter holder 21 is after bent back at the top and designed as a sealing lip 27, which is elastically resilient on the inner surface of the Housing 1 of the collector is present.
  • the liquid phase of the refrigerant flows mainly in the direction shown by the arrows in the annular gap between the filter dryer cartridge 4 and the housing 1 of the collector down and then with a first partial flow in the radial direction through the upper window openings 11 of the filter cage 10 after inside, there again changes its direction of flow and flows axially downwards out of the filter cage 10 and through the outlet opening 3 of the housing 1 from the collector and in the not shown Tube-fin block of the condenser.
  • a second partial flow of the liquid refrigerant passes through the mesh of the screen material 26 then flows radially inwards through the lower window openings 13 of the Filter cage 10 and that covering these openings 13 Sieve material 14 through, combines with the refrigerant flow, who pass through the upper window openings 11 has and flows together with it over the Outlet opening 3 from.
  • the up directional movement of dirt is - different from that downward movement - not by the vibrations the sieve cage 10 supports, so that by the Sieve carrier 21 and the sieve material located on it a kind of "check valve" for the movement of dirt particles is formed.
  • this prevents movement in the backward direction is not complete but only makes it less likely than the movement the dirt particles in the forward direction, i.e. downwards.
  • the filter holder 21 therefore meets in interaction with the annular bowl 18 of the filter cage 10 the function a "dirt trap".
