Definitions

  • Heat exchanger unit in particular for a motor vehicle
  • the invention relates to a heat exchanger unit with at least two heat exchangers, in particular for a motor vehicle, according to the preamble of claim 1.
  • a heat exchanger unit in particular in the form of a monoblock; consists of at least two heat exchangers in one unit, which saves installation space and manufacturing costs compared to a design with separate heat exchangers, and at least two side parts which enclose the heat exchanger unit.
  • mechanical stresses occur between the individual heat exchangers as a result of their differently large thermal expansion, which can lead to leaks, as a result of temperature changes and the associated temporarily different temperature levels in the heat exchangers.
  • the associated tensions between the heat exchangers and the side parts stress the ends of pipes in the heat exchanger unit, which can also lead to leaks here.
  • DE 197 53 408 A1 proposes a heat exchanger which has a ribs / tube block, the side parts of which are provided with expansion joints outside a network structure.
  • at least one expansion section is arranged at the level of the network structure of the fins / tube block.
  • the expansion section can be designed as a fold-like expansion joint or as expansion beads with cutout sections, tensioning straps being passed through the cutout sections for the assembly and soldering of the ribs / pipe block in order to hold the unit together.
  • a heat exchanger unit consists of at least two heat exchangers and has a plurality of tubes and corrugated fins interconnected in the manner of a network structure.
  • at least two side parts enclosing the heat exchanger unit are provided, at least one side part having at least one expansion section.
  • the at least one expansion section preferably extends essentially in a longitudinal direction of the side part. Such an expansion section enables transverse decoupling in the side part of mechanical decoupling of two heat exchangers.
  • a heat exchanger unit according to the invention has a sufficiently large stability of the side parts for transport and manufacture.
  • At least one further stretch section is preferably provided in the at least one side part. seen that runs in the transverse direction of the side part and enables longitudinal decoupling to protect the pipe ends. Such a configuration enables the two heat exchangers to be completely decoupled from one another.
  • At least one opening is preferably provided in the side part, which is arranged between two expansion sections.
  • the expansion section is preferably formed by one or more fold-like beads. If several beads are provided, they are preferably separated from one another by openings. The beads or openings are preferably aligned with one another. This results in better soldering of the two nets due to the hinge effect of the side parts, since the different setting behavior of the two nets is compensated for due to the unequal pipe geometries.
  • the openings are preferably wider than the beads.
  • the width of the openings in the longitudinal direction is preferably between five and ten times as large as the width of the beads in the longitudinal direction of the side surface.
  • the beads are preferably designed such that they are shaped towards the outside. This results in a relatively flat surface on the inside of the side parts.
  • an edge region of the side part is bent by approximately 90 ° along the longitudinal edge of the side part and the expansion section for the longitudinal decoupling is formed by two fold-like beads.
  • the beads are preferably designed such that they are mirror images, wherein they are shaped towards each other.
  • the expansion regions are preferably arranged in a region which is arranged on the outside of the side parts. This results in a relatively flat surface on the inside of the side parts.
  • 1 is a partial perspective view of a monoblock
  • Fig. 2 is a plan view of the monoblock of Fig. 1 and
  • Fig. 3 is a perspective view of a side part.
  • a heat exchanger unit 1 according to the invention in the form of a soldered all-aluminum monoblock has a flat tube condenser 2, a coolant cooler 3, which comprise a plurality of flat tubes and corrugated fins connected to one another in the manner of a network structure, and two side parts 4 lying opposite one another.
  • the side parts 4 have a transverse decoupling 10 in the form of an expansion section 11 for decoupling the flat tube condenser 2 and the coolant cooler 3 and a longitudinal decoupling 20 for protecting the flat tube ends in the form of an expansion section 21.
  • the expansion section 11 for decoupling the flat tube condenser 2 and the coolant cooler 3 is formed by a plurality of fold-like beads 12 which are spaced apart from one another by openings 13 in one
  • Line aligned in the longitudinal direction of the side parts 4 are arranged.
  • the expansion section 11 is arranged closer to the flat tube condenser 2 than to the coolant cooler 3.
  • the width of the openings 13 in the longitudinal direction of the side parts 4 is greater than the width of the fold-like beads 12 in the longitudinal direction of the side parts 4, the width of the openings 13 being approximately six times the width of the fold-like beads 12.
  • the fold-like beads 12 are bent outwards, ie away from the flat tube condenser 2 and from the coolant cooler 3 (see FIG. 1).
  • the expansion section 21 for the longitudinal decoupling 20 for protecting the flat tube ends is formed by part of an edge region of the side parts 4 which is bent outwards by approximately 90 ° and which is provided with a fold-like bead 22.
  • the side parts 4 have a slot-like opening 23 which runs in the transverse direction and extends from one edge region to the opposite edge region.
  • the fold-like beads 22 are designed such that they point towards one another (see FIG. 2).
  • the beads 12 and 22 lie on the outside of the side parts 4, so that an essentially flat surface is provided on the inside.
  • FIG. 3 shows a side part 100 for a heat exchanger unit (not shown) with two different heat exchangers as a further exemplary embodiment in a perspective view.
  • the side part 100 also has a transverse decoupling between an area 110 which is assigned to a first heat exchanger and an area 120 which is associated with a second
  • Heat exchanger is assigned to.
  • the transverse decoupling is accomplished by means of openings 130, so that the areas 110 and 120 are connected to one another only by webs 140, the webs 140 being designed in a curved shape for improved decoupling.
  • edges 150 of the through breaks 130 set up, so that the effect of the raised side panel edges 160 and 170 is enhanced.
  • the side part 100 has transverse openings 180 in addition to the openings 130.
  • Brackets 190 are used to mount the entire heat exchanger unit in a motor vehicle and, for simplification, are formed in one piece with the side part 100.
  • the side parts 4 have a transverse decoupling 10 in the form of an expansion section 11 for decoupling the flat tube condenser 2 and the coolant cooler 3 and a longitudinal decoupling 20 for protecting the flat tube ends in the form of an expansion section 21.
  • the expansion section 11 for decoupling the flat tube condenser 2 and the coolant cooler 3 is formed by a plurality of fold-like beads 12 which are arranged in a line in the longitudinal direction of the side parts 4, spaced apart from one another by openings 13.
  • the expansion section 11 is arranged closer to the flat tube condenser 2 than to the coolant cooler 3.
  • the width of the openings 13 in the longitudinal direction of the side parts 4 is greater than the width of the fold-like beads 12 in the longitudinal direction of the side parts 4, the width of the openings 13 being approximately six times the width of the fold-like beads 12.
