Definitions

  • the invention relates to a heat exchanger, in particular according to the preamble of claim 1.
  • Heat exchangers for air conditioning systems with R134a as the refrigerant consist of a heat exchanger network with flat tubes and corrugated fins and collecting tubes arranged on both sides of the network, preferably with a circular cross section - as known from DE-A 42 38 853 by the applicant.
  • a heat exchanger network with flat tubes and corrugated fins and collecting tubes arranged on both sides of the network, preferably with a circular cross section - as known from DE-A 42 38 853 by the applicant.
  • Extruded manifolds with increased wall thickness have therefore been proposed in WO 98/51983, a manifold consisting of four flow channels arranged next to one another with a circular cross section. The production of such an extruded manifold is expensive because of the tools required for it.
  • Another type of manifold for high internal pressures has been proposed in DE-A 199 06 289, the
  • Collector tube is composed of two or three extruded or pressed parts and has two longitudinal channels with a circular cross section.
  • this known manifold is made of extruded parts, the relatively high tool costs are disadvantageous; if the known manifold is composed of pressed parts, the appears
  • BESTATIGUNGSKOPIE Shape still imperfect, ie not adapted to the expected loads due to the high internal pressure.
  • FIG. 1 Another design for the header box of a conventional capacitor was known from US-A 5,172,761.
  • the condenser has flat tubes which are received in a slot-shaped openings by an essentially flat, but profiled tube sheet.
  • An essentially flat, but also profiled cover part is connected to the tube sheet.
  • Bottom and lid form individual chambers, which are divided by transverse walls, in which the refrigerant flows or is deflected.
  • this shape of a collecting box does not appear to be suitable for higher pressures, such as those that occur in particular in a CO2 refrigerant circuit.
  • the collection box is made from two stamped or bent sheet metal plates, ie there is no machining. This results in low manufacturing costs. Furthermore, the stamping process of the sheet results in work hardening, which increases the internal pressure resistance of the collecting container.
  • longitudinal partition walls with contact surfaces and transverse channels are formed both on the cover and on the base, the contact surfaces being arranged in each case between the tubes or the openings in the base. When joining the cover and base, the contact areas lie flat on top of each other and thus form a large number of soldering areas in the area of the longitudinal partition.
  • Bottom and lid are thus soldered on the one hand in the edge area and on the other hand in the area of the dividing wall, where the soldered contact surfaces form "tie rods" with respect to the internal pressure occurring in the collecting container.
  • the end faces of the longitudinal channels can be closed, for example, by plugs, covers or end walls and, if necessary, then soldered, or they are provided with refrigerant connections.
  • the longitudinal channels can also be sealed at the end by a corresponding deformation of the cover and / or base by soldering them to one another.
  • the flat tube ends, which protrude into the floor or collecting box, are bridged in the area of the longitudinal partition by the arch-shaped transverse channels, so that the refrigerant can escape from the flat tubes over the entire cross-sectional area or enter the flat tubes.
  • the contact surfaces on the inside of the collecting box are designed as elevations and on the outside of the collecting box as depressions or impressions, with depressions or impressions and elevations or expressions corresponding in their position. This production and formation of the elevations on the inside ensures a flat contact surface and thus a secure and firm soldering.
  • the transverse channels that is to say the connections from one longitudinal chamber to another, are designed as depressions on the inside and correspondingly as elevations on the outside.
  • the shape of the transverse channels on the inside ensures free outlet cross-sections of the flat tubes and good solderability of the flat tube ends on the inside due to the formation of a meniscus.
  • the wall thickness in the region of the longitudinal partition walls of the base and lid is approximately constant, and the elevations and depressions are preferably formed symmetrically to a central division plane, a trapezoidal contour being shown in a longitudinal section.
  • the bottom (or also the lid) has marginal ridges or rags in the edge region.
  • the cover and base are thus fixed over the strips or rags before they are soldered together with the entire heat exchanger.
  • three or more longitudinal chambers with two or more longitudinal partition walls are provided, the longitudinal partition walls being designed analogously to the single longitudinal partition wall described above.
  • the collecting container according to the invention can thus also be used for greater flat tube depths without the longitudinal channels taking on an excessively large diameter. This results in advantages in terms of installation space and the strength of the collecting container.

  • a gas cooler is used in refrigerant circuits operated with CO2 as the refrigerant for motor vehicle air conditioning systems, but can also generally be used as a pressure-resistant heat exchanger.
  • Fig. 2 shows a side view of the gas cooler 1 with the header box 2, which is composed of a bottom 4 and a cover 5.
  • Bottom 4 and lid 5 are approximately W-shaped and arranged symmetrically to a parting plane 6, the bottom 4 having edge strips 7 which grip around and fix the lid 5 laterally.
  • Floor 4 and decorative angle 5 form two longitudinal channels 8, 9, both of which essentially have a circular cross section.
  • the flat tubes 3 are picked up from the bottom 4 and project with their flat tube ends 3a into the longitudinal channels 8, 9 approximately up to the dividing plane 6.

  • individual tabs (not shown) can also be provided, since these essentially only have a fixing function for the subsequent soldering process.
  • corrugated fins can be arranged between the flat tubes 3, over which ambient air flows in the direction perpendicular to the plane of the drawing.
  • Fig. 4 shows a section along the line IV-IV in Fig. 3, i. H. a cross section through the collecting box 2 with bottom 4, which receives a (not cut) flat tube 3.
  • a transverse channel 10, which forms a passage, is arranged between the two longitudinal channels 8, 9.
  • Fig. 5 shows the collecting box 2 in an enlarged view without the flat tube 3 with a slot-shaped opening 11 in the bottom 4 for receiving the flat tubes 3.
  • the collecting box 2 has a division level 6, with the exception of the bottom 4 and lid 5 the edge strips 7 and the receiving openings 11 are approximately symmetrical, in particular in the region of a longitudinal partition wall separating the two longitudinal channels, which is formed from a longitudinal partition wall region 12 of the base 4 and from a longitudinal partition wall region 13 of the cover 5, which form superimposed contact surfaces 14, 15.
  • the superimposed contact surfaces 14, 15 are each arranged between the flat tubes 3 and are therefore behind the plane of the drawing in which the Cross channel 10 and - symmetrically to this - another cross channel 16 is located. Both cross channels 10, 16 complement each other to form a common passage cross section.
  • Fig. 6 shows a section along the line VI-VI in Fig. 2, i. H. in the region of the longitudinal partition wall or the two longitudinal partition wall regions 12, 13. The latter abut one another in the region of the parting plane 6 with their contact surfaces 14, 15, which are each arranged between the flat tubes 3.

  • the elevations and depressions result in a trapezoidal meandering profile with an approximately constant wall thickness s for the longitudinal dividing wall regions 12, 13 of the bottom and cover. Since the elevations and depressions - as already mentioned - are produced by embossing, this results in a favorable fiber orientation and high work hardening, which is particularly advantageous for absorbing tensile forces in this area.
