Definitions

  • the invention relates to a heat exchanger profile made of aluminum or an aluminum alloy, in particular for a CO 2 evaporator, and to an evaporator with such a heat exchanger profile.
  • evaporators are widely used in air conditioning systems of motor vehicles.
  • An air conditioning system generally has a compressor, a condenser, an expansion device and an evaporator, wherein these components are usually arranged successively and connected to each other via a fluid-conducting tubes to a circuit.
  • refrigerants such as R134a had proven successful.
  • these refrigerants are harmful to the environment because of their CFC components and should be replaced by less problematic refrigerants.
  • An alternative fluid for the refrigerant circuit of an automotive air conditioning system is, for example, carbon dioxide (CO 2 ).
  • CO 2 carbon dioxide
  • a known flat tube evaporator according to DE 10 2005 004 284 A1 comprises a collecting box, which is divided in the longitudinal direction at least into two chambers and in the bottom of which the ends of the individual flat tubes are inserted. Slats are arranged between the individual flat tubes so that a good heat exchange can take place between the refrigerant flowing through the evaporator and a fluid flowing on the outside of the evaporator.
  • the disadvantage of such an arrangement is that each flat tube individually inserted into a designated opening in the bottom of the header tank, positioned and connected to the collection box.
  • the document DE 101 50 213 A1 discloses such an extruded composite profile of aluminum or an aluminum alloy.
  • This composite profile has two juxtaposed flat tubes, which are connected to one another in the longitudinal direction of the composite profile on their narrow sides via webs. In this bridge can be made for better heat exchange punching.
  • this web is removed at the end. This regional separation of the web at the ends of the composite profile must be very precise.
  • the object of the invention is to provide an improved heat exchanger profile available, which can be produced in a simple manner and meets the high requirements of a CO 2 evaporator.
  • This object is achieved by a heat exchanger profile with the features of claim 1.
  • This heat exchanger profile made of aluminum or a Aluminum alloy is, like the known integrally extruded composite profile, produced with at least two flat tubes, which are connected to one another at their narrow sides via a web. These two flat tubes may have the same or different outer and inner geometries, preferably flat tubes are used with the same height.
  • the flat tubes are connected to one another in the longitudinal direction of the composite profile via a relatively thick web. This web is preferably provided with a small width.
  • the wall thickness of the web is reduced by a one-sided or two-sided narrowing, for example a notch. The wall thickness is thus less than the wall thickness of the web at this point of constriction and it is also less than the wall thickness of the adjacent flat tube.
  • a composite profile can be easily produced by extrusion and cut to the intended length of the evaporator profiles.
  • Such a composite profile may have flat tubes with one or more continuous channels, wherein preferably the channels are formed by perpendicular to the broad sides of the flat tubes arranged channel walls.
  • the size and number of channels for belonging to a composite profile flat tubes can be chosen the same or different.
  • the heat exchanger profile according to the invention can be used in an advantageous and simple manner for high-pressure air conditioning systems, in particular for a CO 2 evaporator.
  • the web is partially removed at the two ends of a composite profile, so that a groove is formed which is sufficiently large that the ends of the flat tubes can be inserted into openings provided the collector profile.
  • This means that the web is removed in a length which corresponds at least to the insertion depth of the flat tubes in the collector profile.
  • the separation of the web or a part of the web is simple but exactly possible because the constrictions of the web represent breaking points for the separation process and thus no It must be ensured that the separating tool between the web and the flat tube engages in order to possibly damage the side wall of the flat tube.
  • the side wall of the flat tube remains unaffected and there is no chip at the radius of this side wall.
  • the flat tubes retain their geometry and can be inserted directly into the openings of the collector profile.
  • the composite profile is provided on its outer surfaces with a solder and / or flux coating, preferably on the broad sides of the flat tubes, in order to achieve a good connection with the arranged between the flat tubes fins during brazing.
  • a brazed joint between the collector profile and the flat tubes can also be achieved, brazing preferably being carried out between the flat tubes and lamellas and between the flat tubes and the collector profile in one production step.
  • a CO 2 evaporators with the inventive heat exchanger profiles is easy to manufacture so.
  • the simultaneous installation of two flat tubes and the simple but precise processing of the ends of the composite profiles saves production time.
  • a known extruded composite profile 1 is shown.
  • the composite profile is preferably made of aluminum or aluminum alloy.
  • This integrally extruded composite profile 1 consists of two flat tubes 2, 3, in this case with the same external and internal geometry.
  • the flat tubes 2, 3 are arranged side by side and connected to one another at its narrow side via a web 4.
  • Such a composite profile 1 is obtained by extrusion, wherein the extruded from the extruder strand is fed to a separator, where the extruded profile is divided into desired lengths of the composite profile 1.
  • the web 4 is to be removed in regions at the end of the respective composite profile 1 so that a groove 7 is formed between the flat tubes 2 and 3 at the end.
  • Fig. 1 the desired separation seam 5 is shown for such a groove 7 in dashed line.
  • the separation is achieved with a punching or cutting tool.
  • a cutting tool directly meets this separation seam 5 and the separation cut is made precisely. A slight deviation from the intended separation seam 5 leads to rework or rejects. If, in fact, the separation cut is made to the left of the separation seam 5, the wall of the flat profile 2 is weakened and the applicable pressure for this profile 2 is reduced, so that it may no longer be usable for a CO 2 evaporator. If the actual operating pressure in the evaporator exceeds this value, the profile may burst.
  • the separation cut is made to the right of the intended separation seam 5, then a remainder of the web remains at the radius of the profiled section 2 or 3, which must be removed so that the end face 8 or 9 of the flat tube 2 or 3 into the appropriate opening on the collector profile can be introduced.
  • a burr usually remains at the radius of the flat profile 2 or 3. This burr must be removed because a CO 2 evaporator is a sensitive system that is very sensitive to contamination. Chips can damage the compressor or clog valves or nozzles. The post-processing to remove the burrs can lead to bending of the narrow side of the flat tubes.
  • This is preferably made of aluminum or an aluminum alloy and consists of the flat tubes 12, 13, in this case, the same outer and inner geometry, namely four channels, which are formed by three channel walls 16.
  • the flat tubes 12, 13 are arranged side by side and connected to one another at their narrow side via a web 14.
  • the web 14 has at the junction with the flat tubes 12 and 13, ie immediately adjacent to these flat tubes 12, 13 a constriction 15.
  • the constriction 15 is generated by a notch on both sides.
  • the thickness w1 of the constriction 15 is less than the thickness w3 of the web 14, and the thickness w1 of the constriction 15 is less than the thickness w2 of the constriction 15
  • the constriction 15 thus represents a so-called predetermined breaking point and it is possible to selectively separate the web 14 in the region of constriction 15 of the flat profile 12 and on the other side in the region of constriction 15 from the flat profile 13.
  • the constriction 15 allows a chipless detachment of the web 14, ie a separation that requires no post-processing.
  • the provision of the constrictions 15 has the advantage that the width b of the web 14 can be selected to be very small.
  • This web 14 serves as an assembly aid, namely for the introduction of two flat tubes 12, 13 simultaneously in the collector profile 20, but otherwise does not contribute to the operation of the CO 2 - evaporator.
  • the width b of the web 14 can be chosen so small that the width b of the wall thickness of the partition wall 24 of the collector 20 corresponds.
  • the web 14 has approximately the cross section of a wire. The choice of such a small width b of the web 4 is not possible with composite profiles 1 according to the prior art, since there must be sufficient space between the flat tubes 2, 3 for the application of the cutting tool.
  • the detachment of the web 14 can take place over the entire extent of the composite profile 10, for example, to separate a flat tube from the composite profile, for example, to share a composite profile with four flat tubes in two composite profiles with two flat tubes.
  • the web 14 can also be separated out in regions, preferably at the ends of the composite profile 10 and there in a length which corresponds at least to the insertion depth t of the flat tubes 12, 13 in the collector tube 20.
  • FIG. 4 shows a connection of the composite profile 10 with a collector profile 20.
  • the collector profile 20 is divided into two chambers 22, 23 by a partition wall 24.
  • the end 18 of the flat tube 12 of the composite profile 10 is inserted into the chamber 22 at an insertion depth t.
  • the flat tube 13 is inserted with its end 19 into the chamber 23. Therefore Furthermore, it is visible that the web 14 connecting the flat tubes 12, 13 is taken out at the end, so that a groove 17 is created, which has made it possible to mount the composite profile 10 on the collecting profile 20.
  • the vaporizer further includes fins, not shown in FIG. 4, which are arranged above and below the composite profile 10, ie, of the flat tubes 12, 13, and are connected to the flat tubes 12, 13 via a brazed joint.
  • the composite profile 10 is preferably provided during manufacture with a solder and flux coating.
  • the connection between the composite profile 10 and the collector profile 20 is achieved via a brazed joint, wherein the good positioning of the composite profile 10 in the collector profile 20 ensures optimal soldering.
  • Such an evaporator is used in particular for a motor vehicle air conditioning system, wherein the cross-sectional shape of the collector profile 20 is independent of the use of the heat exchanger profiles according to the invention, as far as the openings 21 in the collector profile 20 adjacent to each other and the cross sections of the openings 21 and the cross sections of the flat tubes 12, 13 to each other are coordinated.
