Definitions

  • the invention relates to a heat exchanger with a rib - flat tube - Block consisting of flat tubes and ribs arranged between them, whereby the ends of the flat tubes in opposite collection or deflection boxes lead; the ends of the flat tubes are shaped so that one broad side each the flat tubes with the adjacent broad side of the next flat tube is connectable, the collecting or deflection boxes at least partially complete, with the ends of the flat tubes with their narrow sides with Connection edges of the collecting or deflection boxes in contact and by means of Soldering are connected.
  • the invention further relates to production processes for such heat exchangers.
  • the object of the invention is to provide heat exchangers with the characteristics mentioned at the outset and suitable Manufacturing processes for the redesigned heat exchangers indicate that they have much less pressure loss, with the other advantages should be preserved.
  • the ends of the flat tubes are formed such that the broad sides of adjacent flat tube ends at their former inner pages are connected, or that the connection in each case between the outside of the broadside of a flat tube end and the previous one Inside of the broad side of the adjacent flat tube end is provided. It So either two former inner pages are connected to each other, or it is a former inside of the broad side of one Flat tube end with the outside of the broadside of the neighboring Flat tube end connected.
  • the collection or deflection boxes are down (to flat tube ends) through the connected broad sides of the flat tube ends locked. The end faces of the collection or deflection boxes can be opened be locked in another way.
  • the invention is a comparative low pressure loss realized because such a formation of the connection almost flat or wavy, definitely a streamlined and for Collection box-facing area results from the inside of the broadsides is formed.
  • the connection of the broad sides is over the entire width of the Flat tubes provided. In other words, the flat tubes are on the Ends not constricted in their large diameter, which is why there is none Pressure loss is caused.
  • the former inner sides of the broad sides are those sides that are in the flat tube the deformation of the ends are inside the flat tube.
  • the Broad sides are "turned inside out” at the ends, so to speak, with that of Former connection with the adjacent flat tube end
  • Inner sides preferably approximately parallel to the broad sides of the flat tubes are arranged. This also means the distance between the flat tubes of the heat exchanger, which is covered with corrugated fins.
  • the broad sides are in the area of their connection arranged perpendicular or parallel to the flat tubes, whereby they two Have bends of approximately 90 °.
  • the broad sides are in the region of their Connected with an inclined position to the flat tubes, the broad sides have a bend of about 90 ° and a second that corresponds to the angle of the Inclined position corresponds.
  • the roughly flat or preferably corrugated surface has one or two Outflow funnel into the flat tubes.
  • the surface is definitely designed that if possible only a negligible pressure drop when the By means of the flat tubes.
  • the flat tubes themselves are made of two in one embodiment Half shells formed.
  • the former inside of the broadside is in this Embodiment then the side with an assembled flat tube represents the inside broad side of the flat tube or the half-shell. Because of for further details, reference is made to DE 100 16 113.8, which as of this Place disclosed should apply.
  • drawn or welded flat tubes are provided at the ends in their narrow sides have at least one cut that divides the ends into two parts that are reshaped. The deeper the separating cut is made, the larger it can be already mentioned distance between the flat tubes can be executed. Conversely, a smaller distance can consequently be realized with a smaller depth become.
  • a manufacturing method sees if welded or drawn flat tubes are used before that the narrow sides of the Flat tube ends are separated that the two broad sides of the Flat tube ends are deformed so that their former inner sides are outside and are at a distance from the broad side of the flat tube that the Flat tubes with the flat tube ends thus shaped with the ribs for ribbing - Flat tube block are joined together, the former inner sides of the Broad sides of adjacent flat tube ends joined together and when soldering the Ribs - flat tube blocks are connected.
  • the flat tube ends can be sharpened beforehand , rectangular cross section. This step can be taken for granted omitted if the flat tubes already have an approximately rectangular cross section have relatively sharp bending edges.
  • the rectangular cross section creates better conditions to fit the narrow sides of the flat tubes with the To be able to solder the connection edges of the collection boxes tightly and durably.
  • the narrow sides are at least where the broad sides are adjacent Flat tube ends are connected by squeezing or similar deformation been eliminated.
  • Another manufacturing method according to the invention for heat exchangers Flat tubes from half-shells provides that the ends of the half-shells Flat tubes are deformed so that the former inside of the broad sides outside and at a distance from the broad side of the half shells that the Half-shells to the flat tube and the flat tubes with the ribs to rib - Flat tube block are joined together, the former inside Adjacent half-shells of adjacent flat tubes joined together and at Soldering the finned flat tube block.
  • FIG. 1 shows a heat exchanger in which only the upper header box 5 is shown.
  • the lower collecting box 5, not shown, at the opposite ends 4 of the flat tubes 2 can be identical or similar.
  • the entire heat exchanger, consisting of the flat tubes 2 arranged in series, with corrugated fins 3 arranged in between, the collecting boxes 5 and connecting elements, not shown, was produced from solder-coated aluminum sheet, which has long been part of the prior art.
  • the exemplary embodiments shown are welded flat tubes 2 with a longitudinal seam, not shown, which are relatively thin-walled and very inexpensive to manufacture.
  • flat tubes 2 are used, which consist of two half-shells, which are joined together in the narrow sides 8 , on the center 30 , and are later soldered.
  • flat tubes 2 with relatively narrow narrow sides 8 are used.
  • a separating cut 20 is made on the center 30 of the narrow sides 8 , the parts 20a and 20b being formed, and then the parts 20a and 20b , as shown in FIG. 8, are gradually formed.
  • the edge on the formed broad sides 6 which is a hindrance for the later connection of the broad sides 6 to one another, has been approximately leveled by pressing.
  • the forming it must be said that the same is carried out in a forming machine equipped with a follow-up tool, with a completely formed flat tube 2 being ejected with each working stroke.
  • the flat tubes 2 prepared in this way are assembled in an alternating sequence with corrugated fins 3 to form a fin-flat tube block, the previous inner sides 10 of the broad sides 6 of the flat tube ends 4 being in contact in this exemplary embodiment, so that they can be connected later when soldering the heat exchanger.
  • Suitable mechanization and automation means are also available for the assembly process, the use of which is intended according to economic aspects.
  • the heat exchanger described so far is the coolant cooler of a motor vehicle.
  • the exemplary embodiments shown in the other figures are an air-cooled intercooler.
  • flat tubes 2 with wider narrow sides 8 are used, which are usually later equipped with inner inserts, not shown, in order to improve the efficiency of the heat exchange.
  • 7 shows that the flat tube ends 4 are first brought to a sharp-edged rectangular cross-section by inserting a corresponding tool. This operation is optional and depends on the shape of the flat tubes 2 present. Thereafter, as shown in FIG. 6, in contrast to the exemplary embodiment described above, two separating cuts 20 are made on all flat tube ends 4 in their two narrow sides 8 . This results in the parts 20a , 20b and 20c at the flat tube ends 4 which were designated in FIG. 6.
  • the two side parts 20a and 20b are then, as already described, formed.
  • the middle relatively wide part 20c is folded inwards, which is also not a necessary measure.
  • the rigidity in the narrow sides 8 can thus be increased and the later connection to the connecting edges 7 of the collecting boxes 5 can be influenced positively.
  • all parts 20a and 20b of the flat tube ends 4 are each provided with two fairly sharp-edged bevels 15 , so that the surface 11 (FIGS. 3 and 4), which after the assembly of the flat tubes 2 with the corrugated fins 3 and the then the following attachment of the collecting boxes 5 results is relatively flat. It is interrupted at regular intervals by inflow funnels 12 in the flat tubes 2 . This can be seen from FIGS. 2 and 4. Such a flat surface 11 with inflow funnels 12 creates good flow conditions which make it possible to expect a very low pressure loss of the medium flowing through the flat tubes 2 .
  • the broad sides 6 were deformed such that two broad sides 6 each form approximately a semicircle.
  • Further exemplary embodiments show a semi-elliptical design in this regard.
  • the design shown in the figures mentioned is very favorable not only in terms of the low pressure drop but also in terms of stability, since the wall thickness of the flat tubes 2 is usually substantially less than 1 mm.
  • an additional measure has been provided to increase the stability, which, as shown there, consists in that one of the two adjacent broad sides 6 has been bent over 50 at the bottom.
  • the bend 50 also contributes to the fact that the soldering to the connecting edges 7 of the collecting boxes 5 is improved.
  • connection between the broad sides 6 of adjacent flat tube ends 4 takes place in that when the ribbed flat tube block is joined together, the former inner side 10 of the broad side 6 of the one flat tube end 4 is applied the outside 13 of the broad side 6 of the adjacent flat tube end 4 is applied.
  • the connecting surface formed between the outside 13 and the former inside 10 is arranged approximately perpendicular to the longitudinal direction of the flat tubes 2 .
  • Such variants are provided, for example, because in some applications the flat tubes 2 are made of aluminum plate that is solder-plated only on the outside 13 . Furthermore, it is advantageous if, as shown in FIGS.
  • a pre-fixation 40 is carried out in the connection between the adjacent flat tube ends 4 , which unites the ribbed flat tube block before it is assembled with the header boxes 5 and before soldering provides temporary support.
  • the pre-fixation 40 can be produced with a tool that partially interleaves the adjacent surfaces.
  • equivalent pre-fixations 40 are available to the person skilled in the art.
  • a pre-fixation 40 is also possible in the previously described exemplary embodiments.
  • the bend 50 described above also acts like a pre-fixation 40 .
  • connection of the broad sides 6 is provided over the entire width of the flat tubes 2 .
  • the flat tubes 2 are not constricted in their large diameter D at the ends 4 , which is why no pressure loss is caused there either.
  • FIGS. 5 and 11 each of which shows plan views of a single flat tube 2 with a deformed end 4 , which belong to the first exemplary embodiment, in which the former inner sides 10 of the broad sides 6 of adjacent flat tube ends 4 are connected to one another.
  • the connection over the entire width of the flat tubes 2 has also been provided in the second exemplary embodiment (FIGS. 12-15), in which the former inner side 10 is connected to the outer side 13 .
