Definitions

  • the invention relates to a heat exchanger, in particular a Condenser for an air conditioning system for motor vehicles according to the preamble of claim 1.
  • Soldered heat exchangers in particular condensers for motor vehicles consist of aluminum parts, which at first mechanically joined, then in a soldering oven spent and soldered there in one operation.
  • the Parts of such a heat exchanger are flat tubes, often extruded Multi-chamber tubes, corrugated ribs, which together with the flat tubes the so form said block, and headers, which are called passages have, in which the flat tubes are inserted with their ends.
  • These Heat exchangers, in particular capacitors are usually Laflutig flows through, d. H. the headers are separated by partitions Chambers, inlet chamber, deflection chambers and outlet chamber, divided. The partitions are additional parts that are mounted with the manifolds become.
  • the partitions by extension the flat tube ends are formed by the extended flat tube ends Completely fill in the cross-section of the manifold and at the edge with are soldered to the manifold.
  • the passage extends in its longitudinal direction from a flattened Inner wall to the other flattened inner wall of the manifold, so the extended flat tube end with its narrow sides on the flattened Inner wall portions of the manifold is applied and soldered there can.
  • the extension of the flat tube end opened laterally, so that the fluid which the Flat tubes flowed through, from the extended flat tube end in the Pass collecting pipe or enter from the manifold in the flat tube can.
  • the opening takes place in such a way that a longitudinal wall of the Flat tube, which is advantageously designed as a multi-chamber tube, is subsequently removed, for. B. by cutting removal or others Method.
  • a longitudinal wall of the Flat tube which is advantageously designed as a multi-chamber tube, is subsequently removed, for. B. by cutting removal or others Method.
  • an edge remain standing, which surrounds the opening or crossover cross section.
  • the longitudinal wall of the flat tube is in the area of extension only so far removed that the webs, which the individual flow channels form, remain standing. This will be a Stiffening of the relatively thin remaining longitudinal wall achieved.
  • the object of the invention is also characterized by the features of Claim 8 solved.
  • the Heat exchanger has formed as flat tubes side parts, which form with their extended ends the end walls of the headers and close them.
  • the advantage is achieved that additional cover or caps do not have to be used as end walls.
  • the heat exchanger receives a higher stability.
  • the extended Flat tube ends which form the end walls of the headers, inside open, so that formed as a flat tubes side parts also from the fluid of the heat exchanger can be flowed through.
  • This will be two additional tubes in connection with a side part (double function) won.
  • the flat tube used as the side part d. H. With Extension also for the production of partitions, as above described, are used. This also results in another Simplification, as thus partitions and end walls to complete the Collecting tubes with the same flat tube type can be produced.
  • Fig. 1 shows a condenser 1 which can be used for an air conditioning system of a motor vehicle.
  • the condenser 1 consists of a block 2, which is constructed from flat tubes 3 and corrugated fins 4.
  • manifolds 5, 6 are arranged, in which the flat tubes 3 open with their ends.
  • the manifold 5 is divided by two partitions 6, 7 and the manifold 6 by two further partitions 8, 9 in chambers 5a - 5c, 6a - 6c.
  • the condenser 1 is traversed by a refrigerant of a refrigerant circuit, not shown, of an air conditioner, wherein the entry is indicated only by an arrow E and the exit by an arrow A.
  • the condenser 1 is thus traversed in a serpentine and five-flute from the input to the output.
  • Fig. 1a shows a view from the side, from which it can be seen that the width of the manifolds 5, 6 corresponds approximately to the depth of the flat tubes.
  • the condenser 1 is flowed through by ambient air, represented by an arrow L, via the ribs 4, wherein the heat of condensation of the refrigerant is discharged to the ambient air.
  • Fig. 2 shows the detail X of Fig. 1, ie the partition 6 in the manifold 5, in which the flat tubes 3 open.
  • the manifold 5 is integrally formed, for. Example, as a welded tube, and has on its underside 5 d a plurality of passages 10, in which the ends 3 a of the flat tubes 3 are used and soldered.
  • the partition 6 is part of an elongated flat tube 11, wherein the partition wall 6 forms the extension of the flat tube.
  • the extended flat tube 11 is also inserted in a passage.
  • the flat tube 11 is formed as well as the other flat tubes 3 as a multi-chamber tube and thus has two longitudinal walls 6a, 6b in the region of the partition wall 6.
  • the longitudinal wall 6a of the flat tube 11 thus forms the partition wall 6 to the adjacent chamber 5b.
  • the distance between the flat tubes 3, 11 is equal and corresponds to the pipe pitch t R.
  • Fig. 3 shows a section along the line III-III in Fig. 1, ie with a view of the partition wall 7 between the chambers 5a and 5b.
  • the partition 7 corresponds to the partition 6 and is part of an elongated flat tube 12, which is inserted through a passage in the manifold 5.
  • the cross section of the collecting tube 5 is substantially circular, but has flattened side regions 13, 14.
  • the flat tube 12 is - as already mentioned - as a multi-chamber tube with a plurality of flow channels 12 i formed and has narrow sides 12a, 12b, which bear against the inner sides of the flattened side regions 13, 14.
  • the flat tube 12 is extended so far and adapted in its final contour that it fills the entire inner cross section of the manifold 5.
  • the partition wall section 7 of the flat tube 12 has a crossing cross-section 7a, ie an area where the longitudinal wall of the flat tube 12 has been removed.
  • a circumferential edge 7b is left (see also FIG. 6).
  • Fig. 4 shows the detail Y of Fig. 1a, ie the partition 6 in a view from above.
  • the flat tube 11, whose extension forms the partition wall 6, has a plurality of flow channels 11 i, which are delimited by longitudinal walls 6 a, 6 b, wherein in the region of the cross section of the collecting tube 5, the longitudinal wall 6 b is removed.
  • the partitions 6 and 7 are so on the inner wall of the manifold 5 that a dense soldering is achieved.
  • FIG. 5 shows a further exemplary embodiment of the invention, namely an elongate flat tube 15, which functions as a side part of the condenser 1 and at the same time as an end wall end 16 of the collecting tube 6.
  • the flat tube 15 is just like the previously described elongated flat tubes 11, 12 formed with their partition wall approaches 6, 7, ie a longitudinal wall 16 a, ie the interior of the manifold 6 facing side is removed, while the outer longitudinal wall 16 b forms the end wall 16.
  • the collecting tube 6 has for receiving the flat tube 15 end no pulling, but only an outwardly open notch 17, which receives the elongated flat tube 15.
  • the latter thus fulfills three functions, namely that of a flow-through flat tube, a side part and an end wall for the manifold 6.
  • Fig. 6 shows an elongate flat tube 18 with an extension 19, which can be used both as a partition wall and as an end wall.
  • the flat tube 18 is - as mentioned above - formed as a multi-chamber tube and has an upper curved end contour 20, from which flow channels 18i emerge.
  • the flat tube 18 has a front lying in the plane of the longitudinal wall 18a, which is removed in the region of the partition wall portion 19, so that a window in the form of a transfer opening 21 is formed, through which the flow channels 18i and webs 18k are exposed.
  • a peripheral edge 22 surrounds the overflow opening 21 as a frame, whereby a stiffening of the partition wall portion 19 and a protection against the sharp burrs of the webs 18k is achieved. By the webs 18k, which are not removed, there is a further stiffening of the partition wall in the region of the window 21st
