Definitions

  • the invention relates to a heat exchanger, in particular for motor vehicles, having the features of the preamble of claim 1 and of claim 5.
  • the known cooler has an advantageous embodiment of a divided by a partition in two parts collection box in which a series of flat tubes opens with its one end, the flat tubes are divided by a longitudinal separating web in opposite directions through channels.
  • the longitudinal divider ends in front of the closed other end of the flat tubes.
  • the longitudinal divider is there formed as an inserted rod or as a bead in the wall of the flat tubes, which was leveled at the other end of the flat tubes a piece. Both the rod to be inserted and the piece of the bead to be leveled pose an obstacle to a cost-effective production process.
  • the object of the invention is, based on the cited prior art, to achieve manufacturing advantages and / or the applicability of such heat exchanger widening advantages.
  • the solution according to the invention results from both the characterizing features of independent claim 1 and by the characterizing features of independent claim 5.
  • the claim 1 provides primarily manufacturing advantages, because the closure of the ends of the flat tubes can be made easier. Producing the cutouts is easier than the leveling of the bead, which is done in the prior art. This is especially true when the flat tubes are extremely flat, as provided for example in coolant coolers of the motor vehicle engine. (clear width 1 mm or less) The production of the cutouts can, for. B. simultaneously with the cutting or cutting of endless flat tubes.
  • the claim 5 adds these advantages nor the extension of the usability of the heat exchanger.
  • the mentioned in claim 5 closure of the other end of the flat tubes can also be prepared simply by the fact that the ends are folded, squeezed wide and later sealed.
  • the claim 7 provides that the flat tubes should have different lengths.
  • heat exchangers are made available by very simple means, the front surface has a deviating from the usual rectangle or square design.
  • the front surface has a deviating from the usual rectangle or square design.
  • such a design of the front surface can be realized, which is adapted exactly to the example round or arcuate shape of the opening in a fan cover.
  • This proposal makes it possible, more generally speaking, to provide heat exchangers which are also better suited, ie. H. easier to be adapted to the space, for example in the vehicle.
  • the heat exchanger has at least two rows of flat tubes, one row being connected to one side or compartment of the header tank and a second row being connected to another side or compartment of the header tank. All flat tubes
  • the flat tubes may be extruded multi-chamber tubes.
  • the flat tubes can also be manufactured as an endless metal strip, d. H. formed and soldered or welded, flat tubes may be formed with a L Lucasstrennsteg.
  • the longitudinal separating web is preferably formed in that the longitudinal edges of the sheet metal strip form the longitudinal separating web. Both longitudinal edges touch approximately in the middle of the flat tube and form there the longitudinal separating web.
  • the heat exchanger according to the invention also promises a very good heat exchange efficiency, because the heat exchange is provided by the so-called cross-countercurrent principle.
  • the cooling liquid flows back within the flat tubes in a channel and in a parallel channel of the flat tubes in countercurrent and cooling air flows transversely to the flat tubes between them and through heat exchange body (corrugated fins) therethrough.
  • At least one collecting box which has at least one partition which divides this collecting box into an inlet part and an outlet part.
  • the heat exchanger according to the invention has "at least one" collecting box, it should include, for example, two directly adjacent or associated collecting boxes, wherein an inlet box and an outlet box are present.
  • the figures refer to different versions of air-cooled cooling liquid coolers, which are made entirely of aluminum, without thereby limiting the applicability of the heat exchanger to the stated purpose.
  • the cooling liquid flows through the flat tubes 2 and the cooling air flows transversely through it through heat exchanger body 3 (corrugated ribs), which are arranged between the flat tubes 2 and connected therewith in a heat-conducting manner.
  • the corrugated fins 3 were not shown in FIG. 1 , they have been indicated for this purpose in FIG. 4.
  • the heat exchanger according to FIG. 1 has a collecting box 1, in which there is a partition wall 11 , which can be seen by a dashed line.
  • the partition wall 11 separates the collecting tank 1 into an inlet side 12 and an outlet side 13.
  • an inlet 31 is located on the inlet side 11 , and consequently an outlet 32 is arranged on the outlet side 1 were.
  • Fig. 1 a single row of flat tubes 2 with corrugated fins 3 .
  • the flat tubes 2 are connected at one end 21 fixed and tight with the collection box 1 such that the cooling liquid can flow as described.
  • All flat tubes 2 have a longitudinal separating web 23 which divides the flat tubes 2 into two channels 24 and 25 through which they flow in opposite directions.
  • dashed lines were only drawn in the first flat tube 2 for this purpose.
  • the position of the partition wall 11 in the collecting box 1 is matched to the position of the longitudinal separating web 23 such that adjusts the opposite direction of flow.
  • the other ends 22 of the flat tubes 2 are formed accordingly.
  • the formation of the ends 22 can be done, for example, as shown in Figs. 4-8.
  • Characteristic and the various representations in common is that a cutout 30 in the wall 26 of the flat tubes 2 is present, which has been sealed by means of a closure piece 10 .
  • the longitudinal separating web 23 in the region of the cutout 30 has been removed so that the cooling liquid can pass from the one channel 24 into the other channel 25 .
  • the cutout 30 with a semi-circular shape has been made in both wide walls 26, 27 of the flat tubes 2 .
  • the closure piece 10 was there, roughly speaking, formed as a single deformed metal strip whose width corresponds to that of the flat tubes 2 .
  • the sheet metal strip has a corresponding plurality of folds that correspond in dimension to the distances of the individual flat tubes 2 and the depth of the cutouts 30 .
  • the metal strip thus has a meandering shape. It may additionally be provided with impressions directed towards the flat tube ends 22 , each impression fitting into the end 22 of a flat tube in order there to improve the tightness of the connection. (Not shown)
  • FIG. 5 only one broad side 26 of the flat tube ends 22 has always been provided with a cutout 30 .
  • the flat tubes 2 are arranged so that there are always opposite two cutouts 30 , which can then be closed with an approximately U-shaped closure piece 10 ', which is in each case to be inserted into the distance between two flat tube ends 22 .
  • the cutouts 30 are designed there so that in the broad side 26, which has the cutout 30 , at the end 22 of the flat tubes 2 still a web is obtained.
  • each flat tube 2 has been cut out and each flat tube end 22 has been allocated its own closure piece 10 ' , which is correspondingly shaped.
  • Fig. 8 shows the end 22 of a multi-chamber flat tube.
  • Such flat tubes 2 are preferably produced by extrusion processes.
  • the cutout 30 is approximately triangular. There, too, a jetty was left at the end of 22 .
  • FIGS. 2 and 3 two heat exchangers have now been shown, the flat tubes 2 and flat tube ends 22 are formed as described. With regard to the design of the flat tube ends 22 , however, another embodiment could also be provided.
  • 2 and 3 show two heat exchangers that agree that there are two rows of flat tubes 2 , which are connected at opposite sides 1.1 and 1.2 of the header tank 1 with its one ends 21 , in such a way that the drawn and already flow through the heat exchanger described sets, because a partition wall is also located in the collection box 1 to 11.
  • the pipe lengths L up in two rows on continuously in such a way that the longest flat tubes 2 are provided in two diagonally opposite corner regions of the heat exchanger once and the other in the two corner regions the shortest flat tubes 2 are present, as both figures show.
  • FIG. 2 The difference between FIG. 2 and FIG. 3 consists in the fact that in FIG. 2 a collection box 1 with approximately triangular cross-section was used, so that the two rows of flat tubes 2 and heat exchanger bodies 3 are at a corresponding angle to one another. This also leads to a better utilization of space under the hood of a motor vehicle. In FIG. 3, in contrast, both rows are in a common plane.
