Definitions

  • the invention relates to a receptacle with collector for the desiccant of the refrigerant in an air conditioning system for motor vehicles, which has the features further listed in the preamble of claim 1.
  • This collecting device with collector is known from FR 2 750 761 A1.
  • Further recording devices are known from EP 1 147 930 B1 and from a number of other publications.
  • the drying agent is usually housed in a flow-through container.
  • the receiving device is usually made of a suitable plastic with openings in the entire wall, so that it represents a closed, cage-like container in which the flow-through container with the desiccant is.
  • This known design has little functional disadvantages, however, it has been found that the use of such recording devices is a not inconsiderable cost factor.
  • the manufacturers and the users are different companies, with the manufacturers offering the receiving device with the desiccant included as a product.
  • a significant functional disadvantage of the known receiving device is that the granular drying agent is ground in a relatively short time due to abrasion, whereby its effect wears off. The abrasion must be filtered out of the refrigerant.
  • the present invention has for its object to provide a recording device with collector, which delays or reduces the abrasion of the drying agent.
  • the solution according to the invention is carried out with the features of the plate in claim 1. It is provided that the side of the receiving device closest to the inflow opening is formed substantially closed by the wall at least in the area of the inflow opening / s for the purpose of flow diversion and that between the side of the wall and the wall remote from the inflow opening (s) the collector of the receiving space is formed for the drying agent, wherein the wall of the receiving device is either a one-sided open profile whose cross-section, for example, arcuate shape, or the wall is flat.
  • the wall is substantially closed towards the inlet opening, it is achieved that the refrigerant can not flow directly onto the desiccant, which has proven to be the cause of the rapid abrasion of the desiccant.
  • the closed design of the wall represents a flow deflection.
  • the refrigerant can be deflected laterally and / or upwards and downwards and thus more uniformly wets the desiccant.
  • the desiccant remains operational for a long time.
  • the flow deflection promotes the separation of the still gaseous portions of the refrigerant from the liquid portions.
  • the desiccant and the receiving device can be provided as individual parts and, in addition, much more cost-effectively, in the completion of the condenser, together in the Collectors are used.
  • the cross section of the wall of the receiving device is a one-sided open profile and has approximately arcuate shape.
  • the drying agent can be used easily.
  • the wall can also be unprofiled, d. H. just be trained without having to accept significant disadvantages.
  • the two edges of the profile or the wall against the wall of the collector are provided above the inlet opening with openings, whereby the flow resistance for the refrigerant is kept within limits. This training is required at adjacent edges, so that the refrigerant can flow.
  • a filter basket is preferably releasably attached to the wall of the collector towards a seal and below the seal is a filter.
  • the filter basket is preferably cylindrical in cross section.
  • filtered residues can accumulate from the refrigerant, which can be removed by loosening the cap and removing the recording together with the filter basket.
  • the lateral flow around the wall 7 has been substantially prevented, because, as shown in FIG. 3, the wall 7 rests with its two edges 32 on the wall 12 of the collector 4 approximately on the median plane 50 .
  • This Concern of the wall 7 on the wall 12 improves the positional stability of the receptacle 1 in the collector. 4
  • was dispensed with the two-sided concern of the edges 32 whereby the lateral flow around the wall 7 is possible. In this embodiment, then could possibly be dispensed with the openings 11 in the wall 7 .
  • FIG. 7 an alternative embodiment in a section, similar to FIG. 2, shown, in which case the representation of a collecting tube 2 has been omitted.
  • the receiving device 1 consists of a cage-like container in which the desiccant 34 is in the dryer bag 33 , which, however, was not shown in Fig. 7.
  • the container 1 and the collector 4 have a round cross-section, as the sketched section is to show just above the inlet opening 8 .
  • the wall 7 has a plurality of openings 11 in a freely selectable manner.
  • the wall 7 was formed without openings 11 , ie as a closed wall 27 , in order to prevent the flow (arrows) from hitting the drying agent directly. Therefore, the desiccant remains effective for a longer period of time.
