Definitions

  • the invention relates to a heat exchanger for evaporators, in particular for air conditioning systems, with a structure corresponding to the preamble of claim 1.
  • the present invention is based on a heat exchanger, as has been proposed in the older DE-AS 27 28 827 by the applicant, in which the strength of the connection between the water pipes made of metal and the connection boxes made of plastic has been increased so that the application this design can now also be considered for evaporators.
  • the invention is based on a heat exchanger, as can be seen from DE-OS 21 35 647, in which distribution and collection spaces, each with a plurality of insertion and return openings, are arranged in aluminum connection boxes.
  • connection boxes made of plastic have become known in the obvious technical fields of heat exchangers in recent years, this design, which has meanwhile been introduced into large-scale production in heat exchangers, could not be used for evaporators, since the strength of the connection between the water pipes made of metal and the connection boxes made of plastic were not sufficient to withstand the operating pressures of up to approx. 40 bar that occur with evaporators, especially for air conditioning systems.
  • the object of the invention is to apply such a simpler design also for evaporators, whereby this should not only be taken over, but further measures which reduce the production costs and improve the cooling capacity should be carried out.
  • connection box consists of a distributor part and a connection part, which are sealed and firmly connected to one another via a tongue and groove connection by means of a hardenable plastic, simplifies the manufacture of such a connection box and thus reduces its production costs.
  • a plurality of injection openings or a plurality of return openings parallel injection and return spaces are formed in the distributor part, which are combined again via two corresponding end merging collecting spaces, the injection and return paths of the refrigerant one kept to a desired small size and on the other hand guided in insulating plastic, so that the loss of cold, which is hardly avoidable in known evaporators, is prevented and thus the effective digging power of the evaporator is increased.
  • connecting pipes for the injection valve and the compressor suction line in one piece with the connecting part and with molded-on collars enables a further simplification of the production, the assembly by means of split, foldable union nuts still being able to be carried out simply and reliably.
  • connection box 1 made of plastic, which is sealed and firmly connected to a tube bundle of evaporator tubes 3 made of metal, which is held together by air-guiding fins 2 made of aluminum, via a hardenable plastic 4 embedding the tube ends.
  • the Ansohlußkasten 1 consists of a distributor part 5 and a connecting part 6, the structure of which is explained in more detail below in connection with the corresponding figures.
  • the connector 6 is shown. It has a connecting pipe 7 for the injection valve 8 and a connecting pipe 9 for the compressor suction line (not shown). Both connecting pipes 7 and 9 are provided at their ends with integrally formed collars 10, by means of which they can be fastened via split, foldable union nuts 11 with the interposition of a sealing ring 12 in a threaded bore 13 in the injection valve 8 or on the compressor suction line.
  • connection side of the connection part 6 is provided with grooves 14 and 15 which merge into one another and form endless loops, the purpose of which will be explained below.
  • FIG. 4 shows the distributor part 5. It has a base 6, from which a plurality of pipe sockets 17 protrude, which are surrounded by ring webs 19 which form axially open annular grooves 18.
  • the pipe socket 17 form a plurality of injection openings labeled E and a plurality of return openings labeled R.
  • one pipe socket of an injection opening E is connected to the inlet end of a U-shaped evaporator pipe 3, the outlet end of which is connected to the adjacent pipe socket of the return opening R indicated in broken lines (FIG. 4).
  • the course of the grooves 14 and 15 in the connection side of the connection part 6 is in accordance with the recall of the springs 20 and 21 on the connection side of the distributor part 5.
  • the axially open annular grooves 18 present at the bottom 16 of the distributor part 5 can be filled with a hardenable plastic 4 and then the tube ends of the tube bundle consisting of a plurality of evaporator tubes 3 made of metal by sinking into the annular grooves filled with hardenable plastic and subsequent hardening of the plastic sealed with the junction box 1 and firmly connected.
  • connection box 1 enables simple manufacture of the individual components, the distributor part 5 and the connection part 6 and enables the connection of these two components practically in the course of establishing the connection between the connection box 1 and the tube bundle of evaporator tubes 3.
  • the introduction of the curable Plastic in the grooves 14 and 15 of the connection part 6 can take place at about the same time as the introduction of the plastic into the ring grooves 18 on the distributor part 5, after which the two parts of the connection box 1 and the evaporator tubes 3 can be brought together with the connection box 1 and the whole Evaporator block can be completed in a curing operation.
  • the depths of the grooves 14 and 15 in connection with the height of the springs 20 and 21 and the flange-like design of the connection sides of the two components of the connection box 1 ensure that the hardenable plastic cannot run in an undesirable manner until the hardening process.
  • the tongue and groove connection of the two components of the connection box tens 1 ensures a connection of high strength, which fully meet the operating stresses of an evaporator.
