Definitions

  • the invention relates to a refrigerant condenser, in particular for a Air conditioning system of a motor vehicle according to the preamble of claim 1 - known from FR-A 2,757,610.
  • Refrigerant condensers are known components of refrigerant circuits for automotive air conditioning systems.
  • the refrigerant occurs as overheated Steam under high pressure in the condenser and is there under levy condensed by heat to the ambient air, sometimes also a Subcooling of the refrigerant is provided before exiting the condenser is.
  • Another component of the refrigerant circuit is a so-called Collector or collecting container, on the one hand as a memory and on the other hand serves as a filter and / or dryer for the refrigerant.
  • They are essentially two designs known in which the collector either with the Capacitor is integrated into a unit or a separate part to Capacitor forms. The integrated collector was through numerous pamphlets the Applicant known, z.
  • DE-A 42 38 853, DE-A 43 19 293 and DE-A 198 48 744 In these types of collector is parallel arranged to one of the two manifolds of the capacitor and over Refrigerant passage openings connected to the manifold. This construction Although very compact, but under certain installation conditions not always the cheapest solution. In such cases, a separate or external collectors be more advantageous.
  • FR-A 2,757,610 such a capacitor with separate Collector known about refrigerant pipes with one of two header pipes the capacitor is connected.
  • the latter is flowed through with multiple flooding and therefore has partition walls partitioned chambers, one behind the other be flowed through, wherein before the exit of the refrigerant from the Condenser is provided a so-called subcooling, in which the refrigerant is cooled below the condensation temperature.
  • the refrigerant before entering the subcooling section via a refrigerant suction line the collector and a Kälteschzuloom impart the subcooling or the chamber assigned to it.
  • the collection container has a bottom and a lid, wherein between bottom and Cover a filter unit is arranged.
  • Both the refrigerant inlet as also the refrigerant outlet for both connecting lines are arranged in the cover.
  • the refrigerant flows through the filter from top to bottom, passes in the bottom of the collector, then flows through a filter piercing riser back up and finally passes through the refrigerant supply line in front of the subcooling section.
  • a disadvantage of this known construction is the riser, which is virtually the entire height the collection container interspersed, resulting in a relatively long refrigerant return line leads to the manifold and means an increased pressure drop.
  • the refrigerant outlet in the bottom of Collecting container is arranged and leads from there directly to the capacitor.
  • a riser and a long refrigerant return are obsolete. from that There are weight and cost advantages and a lower pressure drop for this assembly consisting of collecting container and capacitor.
  • the refrigerant inlet of the collecting container is in its lid arranged and the filter / dryer unit is located between the Inlet and outlet, d. H. it is from the refrigerant, which here largely condensed, flows through from top to bottom.
  • the filter / dryer unit is located between the Inlet and outlet, d. H. it is from the refrigerant, which here largely condensed, flows through from top to bottom.
  • the filter / dryer unit closed up and down through perforated sheets and also kept in the collection container.
  • the perforated plates allow a passage of the refrigerant and take a granule for drying between themselves.
  • one Diverter provided which allows a direct passage of the refrigerant from top to bottom, so without adequate filtering and drying prevent should.
  • This can be done, for example, by a below the refrigerant inlet cross-section arranged baffle made, which is the refrigerant condensate distributed radially outwards and thus for a uniform Flow through the dryer / filter unit ensures.
  • the baffle plate and part of the perforated plate be in which some openings or pores of the perforated plate, the are located below the refrigerant inlet cross-section, closed are. Thus forms in the middle of the perforated plate a stagnation point, the causes a radial outflow of the condensate to the outside.
  • the collecting container between the penultimate and the last flow passage, d. H. between the condensation area and the subcooling distance of the condenser connected ensures that only condensate, d. H. liquid Refrigerant enters the subcooling and effective subcooling takes place.
  • the single figure shows a soldered capacitor 1 with a Tube / rib block 2, called block for short, and two header pipes 3, 4.
  • the Block 2 consists of flat tubes 5 and corrugated ribs arranged between them 6.
  • the flat tubes 5 have on both sides pipe ends, which in the Collecting pipes 3, 4 open.
  • the collecting tube 3 has an inlet chamber 7 with a refrigerant inlet 8 and an outlet chamber 9 with a refrigerant outlet 10 on. Between the two chambers 7, 9 is a deflection chamber 11 arranged.
  • the manifold 4 has three Umlenkkammem 12, 13, 14 on.
  • the refrigerant entering through the refrigerant inlet 8 flows through the condenser 1 in total in four flow passages, wherein the upper area of the condensation area and the lower area between the Chambers 9, 14 located area of the subcooling area.
  • a separate collector or collecting container 15 is arranged, which via a refrigerant supply line 16 with the chamber 13 and a refrigerant return line 17 to the chamber 14 of the manifold 4th connected is.
  • the collecting container 15 has a bottom 18 and a Lid 19 and a dryer / filter unit 20, which is slightly below the Cover 19 is arranged and up through a perforated plate 21 and after is closed at the bottom by a perforated plate 22.
  • the refrigerant inflow pipe 16 opens into the lid 19 and forms there the Refrigerant inlet 16a.
  • the refrigerant drain pipe 17 is at the bottom 18 connected there and forms the refrigerant outlet 17a.
  • Refrigerant inlet and outlet 16a, 17a are formed as screw connections and preferably arranged on the central axis of the container 15.
  • a baffle plate 23 is arranged below the Refrigerant inlet 16 a, which schematically should represent a Strömungsumsch Republic.
  • this Baffle plate 23 is disposed in the upper perforated plate 21, a central region 24, the closed, d. H. is refrigerant impermeable. With this opaque Region 24 or with the baffle plate 23 is a deflection of the condensate exiting the refrigerant inlet 16a in the manner be caused to spread radially outwards and not directly the Filter / dryer unit 20 flows from top to bottom. Below the Perforated metal 22 is a space 25, the storage volume for the Refrigerant can be used.
  • the function of the capacitor 1 with a separate collector 15 is the following: the refrigerant enters the gaseous state through the refrigerant inlet 8 in the condenser 1, flows through the upper portion of the capacitor in alternate directions, d. H. from the chamber 7 to the chamber 12, is deflected there, enters the chamber 11, where it is deflected again is and enters the chamber 13.
