Definitions

  • the invention relates to a heat exchanger with a plurality of parallel flat tubes of the type specified in the preamble of claim 1.
  • a heat exchanger is known for example from EP-A-0 255 513.
  • the ends of extruded flat tubes are guided into elongated slots in a tubular connection box and are soldered to the connection box.
  • the ends of the flat tubes must correspond exactly to the dimensions of the slots so that the tightness of the solder joint is achieved.
  • the corrugated fins are provided with a solder layer in order to be soldered to the flat tubes which have no solder.
  • it is necessary to manufacture different connection boxes for different pipe cross sections a universal use a uniform type of junction boxes for different pipe cross sections is therefore not possible.
  • US Pat. No. 3,689,972 describes a method by which, in a flat tube heat exchanger, after the tubes have been soldered into the terminal boxes, the terminal boxes are deformed to a desired cross-sectional shape. Since the soldering of flat tubes into corresponding slots in connection boxes, in particular in the area of the parallel flat sides, is fraught with problems, it was proposed in EP-A-0 198 581 to provide the bottom of the connection boxes with bulges, which results in better soldering of the Flat tubes with the junction boxes should result.
  • a heat exchanger is also known from FR-A-2 605 726, in which the ends of oval tubes are fastened in a tube sheet and the cover of the connection box is fastened to the bottom of the connection box with the interposition of a sealing cord.
  • FR-A-2 605 726 in which the ends of oval tubes are fastened in a tube sheet and the cover of the connection box is fastened to the bottom of the connection box with the interposition of a sealing cord.
  • the ends of the flat tubes are held in the passages by radial pressure, the radial pressure being generated by widening the tube end or by constricting the passage. This completely eliminates tolerances in the section with radial pressure.
  • connection box is expediently soldered to the connection plate, this solder connection taking place simultaneously with the soldering of the heat exchanger block.
  • the flat tube, the connection plate and / or the connection box consist of a light metal alloy and that these parts are solder-plated.
  • the flat tubes made of a light metal alloy can be attached to the Pipe ends, the connection plate and possibly also the connection box must be covered with a solder foil at the points to be connected.
  • connection box is mechanically fastened to the connection plate with the interposition of a sealant.
  • This sealant is preferably a rubber sheet with a number of openings corresponding to the number of flat tubes, the openings being adapted to the outer circumference of the passages. This results in a large-area seal between the connection plate and the bottom of the connection box, which guarantees reliable tightness.
  • profile strips can be used, which grip laterally over the edge of the connection plate and the connection box and press these two parts against one another. The profile strips are preferably mutually clamped.
  • connection boxes preferably consist of an extruded profile part which is provided in the area of the floor with corresponding openings for receiving the passages of the connection plate.
  • the side ends of the junction boxes are provided with locking pieces.
  • Fig. 1 the section through a heat exchanger 10 is shown, which comprises a plurality of parallel flat tubes 11 and corrugated fins 12 arranged between them.
  • the flat tubes 11 have ends 13 with a round cross section, which are formed directly on the flat tubes 11 without a transition region and project into corresponding openings 14 in a connecting plate 16.
  • the openings 14 in the connection plate 16 are formed by passages 17 which in turn protrude into corresponding openings 18 in the bottom 15 ′′ of the connection box 15.
  • the connection box 15 consists of an extruded profile which, in addition to the base 15 ′′, also includes the cover 15 ′.
  • the lateral end of the connection box 15 is closed by means of a closure piece 20.
  • a side part 19 is soldered on to limit the lateral face of the heat exchanger 10 and to support the respective outer corrugated fin 12.
  • FIG. 2 shows a section along the line II-II of FIG. 1 on an enlarged scale.
  • the connection box 15 consists of an extruded profile having a substantially square cross section, at the end of which a closure piece 21 with a connection 22 is provided for a supply line for the heat exchanger fluid.
  • the passage 17 of the connecting plate 16 projects through the opening 18 in the base 15 ′′ and the round end 13 of the flat tube 11 projects through the opening 14 formed by the passage 17.
  • the round end 13 is fastened in the passage 17 by radial expansion before the Junction box is placed on the connection plate 16.
  • the flat tubes 11, the connection plate 16 and the connection box 15 are soldered together. These solder connections are designated 23.
  • Fig. 3 shows a section along the line III-III in Fig. 1. From this illustration, the completely closed extruded profile that forms the junction box 15 can be seen. It is clear from this that the bottom 15 ′′ of the connection box 15 only has openings 18 where the connection plate 16 has passages 17. Otherwise, this representation corresponds to that in Fig. 2, so that the reference numerals for the same parts also match.
  • Fig. 4 shows a section along the line IV-IV in Fig. 1. This illustration clearly shows that the ends 13 of the flat tubes 11 are round, and the passages 17 are also annular, which through the bottom 15 '' of the Terminal box 15 protrude. On the side of the terminal box 15, the closure piece 20 is attached.
  • the extruded profile can also have a different cross-sectional shape, so that a junction box 25 with a domed lid 25 ', but with a flat bottom 25' 'is created. Openings 24 are provided in the bottom 25 ′′ and are conically tapered towards the inside of the connection box. Due to this shape of the opening 24, when the connection box 25 is placed on the connection plate 16, the passage 17 is pressed radially inward, so that there is a pressure between the end 13 of the flat tube 11 and the passage 17. The junction box 25 is of course pressed onto the passages 17 until the bottom 25 ′′ bears on the connection plate 16.
  • FIG. 6 shows a section through a heat exchanger 30 - similar to that in FIG. 2 - in which a flat tube 31 with a round end 32 is fastened in a passage 33 of a connecting plate 34.
  • a junction box 35 which comprises a cover 35 'and a base 35'', has openings 36 in the base 35''through which passages 33 of the connection plate 34 protrude onto the inside of the connection box 35.
  • a rubber plate 37 is inserted between the bottom 35 ′′ and the connecting plate 34 and has openings 38, the size of which is dimensioned such that the sealing material also bears against the passage 33.
  • an essentially U-shaped profile strip 39 is provided, which laterally engages over the bottom 35 ′′ and the connection plate 34. If the inner contour of the U-shaped profile strips 39 have an opening angle, increasing pressure between the base 35 ′′, the sealing plate 37 and the connection plate 34 can be achieved by pressing the profile strips in the direction of the connection box 35.
  • FIG. 7 shows a section along the line VII-VII in FIG. 6. This illustration shows that the passages 33 with the pipe ends 32 protrude through the bottom 35 ′′ of the connection box 35.
  • the lateral end of the connection box 35 is closed by means of a closure piece 40.
  • the ends of the profile strips 39 protrude beyond the length of the terminal box 35 and each have a bore through which a clamping bolt 41 projects, which has a screw head at one end and can be clamped at the other end by means of a screwed-on nut 42.
