Definitions

  • the invention relates to a heat exchanger for evaporators, in particular for air conditioning systems, with a structure corresponding to the preamble of patent claim 1.
  • the present invention is based on a heat exchanger, as proposed in DE-B-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 was increased such that for the knowledgeable Specialist the application of this design could now also be considered for evaporators with their higher pressure loads.
  • DE-A-2 735 647 discloses a heat exchanger as known, in which distribution and collection spaces, each with a plurality of insertion and return openings, are arranged in aluminum connection boxes.
  • a heat exchanger for evaporators in which a distribution of the liquid coolant or refrigerant, which is as uniform as possible for the good efficiency of an evaporator, over the multiplicity of heat exchanger tubes by a complex multi-part design of the connection box to be solved, in which two heat exchanger tubes are combined via a dome called an inlet tank and several of these domes are combined again via a pipe.
  • the pipeline and the domes are enclosed by an outer connection box, which forms the return space.
  • connection box In its known evaporators, a costly, multi-part construction of the connection box is required for the favorable distribution of the coolant or refrigerant, the individual sheet metal components of which have to be connected to one another in labor-intensive soldering operations.
  • the object of the invention is to develop such a connection box for a heat exchanger for evaporators, starting from the use of plastic connection boxes known in normal heat exchangers, which meets the special requirements for evaporators, namely the most uniform distribution of the liquid coolant or refrigerant a corresponding constructive design takes into account, is much simpler and cheaper to manufacture and enables an improvement in the efficiency of the evaporator by avoiding undesirable cold losses outside the actual heat exchanger zone.
  • 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.
  • 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.
  • the evaporator block shown in the figures consists of a junction 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 one of the tube ends, which is hardenable plastic 4.
  • connection box 1 here consists of a distributor part 5 and a connection part 6, the structure of which is explained in more detail below in connection with the corresponding figures.
  • the connecting part 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 divided, 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.
  • the distributor part 5 is shown. It has a base 16, 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).
  • a plurality of injection openings E or a plurality of return openings R are correspondingly merged via tubular injection and return spaces Eo or Ro located parallel to one another on the connection side of the distributor part 5 via two collecting spaces Es or Rs.
  • the course of the grooves 14 and 15 on the connection side of the connection part 6 is in agreement with the course 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 joined with hardenable plastic and subsequent hardening of the plastic sealed with the junction box 1 and firmly connected.
  • junction box 1 enables simple manufacture the respective individual components, the distributor part 5 and the connection part 6 and 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 curable plastic can be introduced into the grooves 14 and 15 of the connection part 6 at about the same time as the plastic is introduced into the annular 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 entire evaporator block can be completed in one 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 curable plastic cannot run in an undesirable manner until the curing process.
  • the tongue and groove connection of the two components of the junction box 1 ensures a connection of high strength, which fully meet the operating stresses of an evaporator.
