Definitions

  • the invention relates to a condenser for the air conditioning system of a motor vehicle, the tubes of which flow through the refrigerant in several stages, for which it has two manifolds, and has a collector connected to one of the manifolds via inlet and outlet openings between the stages, having an outer sheath.
  • a condenser with vertically extending heat exchanger tubes is shown in FIG. 7 of the EP 769 666 A1 known.
  • the headers are arranged horizontally.
  • the collector runs parallel to the heat exchanger tubes of the condenser and is arranged vertically upright. The vertical position of the collector is favorable with respect to the separation therein between still gaseous and already liquefied refrigerant, and is therefore the most widespread.
  • the heat exchanger tubes are horizontal and thus arranged the manifolds of the local condenser vertically.
  • the collector is located horizontally parallel to the heat exchanger tubes, below the tube - fin block of the condenser.
  • the collector is releasably connected via a soldered connection block to one of the manifolds.
  • the collector has the function of separating gaseous and liquid refrigerants and of collecting a desiccant. This feature may not work as well in the JP publication as it is desired.
  • the inventor has set itself the task of designing its condenser with a collector so that the separation function and / or drying function of the collector is improved.
  • the collector has an inner jacket, the inner jacket and outer jacket being arranged coaxially with one another, so that a flow channel for the refrigerant is formed between the inner jacket and the outer jacket, wherein the one inlet or outlet opening communicates with the space enclosed by the inner jacket and the other inlet or outlet opening is arranged in the outer jacket.
  • a dryer In the room, which is enclosed by the inner shell, there is a dryer and according to an embodiment, a filter.
  • the filter is arranged above the dryer, wherein the cleaned refrigerant after flowing through the filter reverses its direction of flow and enters the said stage of the condenser via the flow channel and the other inlet or outlet opening.
  • only the dryer is located in the space which is enclosed by the inner jacket, and that the filter is arranged in the flow path in front of the outflow opening.
  • the other inlet or outlet opening of the collector is provided approximately at the front end of the collecting tube.
  • Each stage consists of several parallel heat exchanger tubes of the condenser. Furthermore, the provision of the transfer line improves the position of the collector.
  • the collector In Fig. 7 of the EP 769 666 A1 the collector is located in front of or behind the tube - fin block, so that the heat exchange between the cooling air flowing in perpendicular to the tube - fin block and the refrigerant flowing inside the tube - fin block is impaired.
  • the collector is laterally adjacent to the tube-and-finned block, thereby improving the efficiency of heat exchange.
  • the transfer line the refrigerant is transferred from one stage to the other via the other stage into the collector. After flowing through the collector the refrigerant enters the mentioned other stage and flows through it.
  • This other stage may, for example, be a subcooling stage.
  • the transfer line may be located either within the header or outside the header.
  • the compactness is further improved when a transfer line disposed within the manifold is selected.
  • This may be an approximately coaxial tube.
  • the manifold could be divided in the transfer line but also only by a wall.
  • the other inlet or outflow opening is preferably provided directly between the jacket of the collector and the front end of the collecting tube.
  • the collector is located in the immediate vicinity of the tube - fin block, and in particular in the immediate vicinity and parallel to one of the side parts, which usually reinforce the tube - rib block on the sides. If necessary, an additional mounting of the collector can be provided on these side parts.
  • FIGS. 1-4 show an exemplary embodiment with an external transfer line and with a filter located below the container.
  • FIGS. 5-8 show an exemplary embodiment with a transfer line integrated in the collecting tube and with a filter present in the container.
  • Fig. 9 shows a flared manifold with integrated transfer line.
  • stages 1 and 2 each consist of a plurality of flat heat exchanger tubes 15 , wherein between the heat exchanger tubes 15 corrugated fins 18 are arranged, which are flowed through by the cooling air to cool the refrigerant in the heat exchanger tubes 15 and to condense.
  • the refrigerant leaves the condenser 30 in the fully liquefied and supercooled state.
  • the sections of the condenser 30 shown in FIGS. 1 and 5 are therefore in the stage 1 by several stages, which are connected upstream, as can be seen in principle from FIGS. 2 and 6.
  • the steps 1, 2 are formed by the appropriate arrangement of partitions 7 in the headers 3 and 5 .
  • the refrigerant 25 enters the condenser 30 through the inlet and outlet flange 26 . It flows through several stages 1 before it enters the transfer line 10 through the inlet opening 27 . Through the transfer line 10 , the entire refrigerant 25 is guided past the stage 2 and transferred to the collector 4 .
  • the transfer line 10 enters the collector 4 and passes through the space 28 , the filter 29 and above the filter 29, the liquid mixed with small amounts of gas refrigerant 25 via the inflow opening 14 into the interior of the collector 4 from.
  • the desiccant is in a container 12th
  • the refrigerant flows through the filter 29 to separate the smallest particles and into the return flow 28th
  • the dividers 36 are to guarantee that the entire refrigerant 25 flows through the filter 29 .
  • the refrigerant 25 leaves the collector 4 and flows through the front end 35 of the collecting tube 3 into the stage 2 of the condenser 30 .
  • the subcooling in stage 2 After the subcooling in stage 2 , it passes via the collecting pipe 5 and the outlet 19 to the inlet and outlet flange 26, in order then to continue its travel in the air conditioning circuit (not shown). 4, an alternative to the first embodiment is shown. In some cases it may be necessary to place the collector 4 slightly in front of or behind the plane 33 of the tube-fin block of the condenser 30 . The collector 4 is then offset by the distance 32 from the plane 33 to the front or rear, but otherwise identical to the first embodiment.
  • the refrigerant 25 enters the condenser 30 through the inlet and outlet flange 26 . It flows through several stages 1 before it enters the transfer line 10 through the inlet opening 27 . Through the transfer line 10 , the entire refrigerant 25 is passed to the stage 2 over and transferred to the collector 4 . At the flange 8 , the transfer line 10 enters the collector 4 a. The flange 8 is also the inflow opening 14 , through which the refrigerant 25 flows into an inner shell 20 . In the inner jacket 20 , the desiccant is in a container 12th On his way It happens to the above the dryer arranged filter 29 to separate the smallest particles.
  • FIG. 8 also shows an alternative to the second exemplary embodiment. In some cases it may be necessary to place the collector 4 slightly in front of or behind the plane 33 of the tube - fin block of the condenser 1 . The collector 4 is then offset by the distance 32 from the plane 33 to the front or rear, but otherwise identical to the second embodiment.
  • FIG. 9 an alternative embodiment of a transfer line is shown.
  • the manifold 3 was enlarged on the collector 4 side facing 35 in diameter.
  • the manifold 3 has been widened to accommodate the transfer line 10 so that the returning refrigerant 25 undergoes no unnecessary pressure loss through a too narrow manifold 3 .
  • the installation of the transfer line 10 is easier to accomplish.
